Let’s talk about the maintenance key points of the two main components of a precision electric sliding table.

2022-12-23

This section discusses the maintenance key points of the two main components of precision electric sliding tables. The two key points for maintaining precision electric sliding tables are as follows: We know that precision electric sliding tables are generally used as mechanisms in parallel motion transmission systems. They are particularly important mechanical components within the internal structure of linear modules. Their condition and reliability are related to the speed and accuracy of reciprocating motion of all linear module transmission systems. Therefore, we must perform moisture retention and maintenance after the equipment has been tested and is in good condition. So how should we maintain them? Here are the maintenance key points for the two main components of precision electric sliding tables. Why is it important to pay attention to the daily maintenance of ball screws and guide rails? The main reason is that proper maintenance can ensure the precision and efficiency of the precision electric sliding table and the reliability of its application research process. It can also extend the machine's lifespan. In fact, the daily management and maintenance of precision electric sliding tables are not too complicated unless the usage scenarios make it seem overly chaotic. Precision electric sliding tables come in two types: fully enclosed and semi-enclosed. The fully enclosed module does not require daily maintenance, as it uses a special self-lubricating bearing mechanism that can operate for 3000 kilometers under light load. On the other hand, the daily maintenance of the semi-enclosed DK series products' screws and guide rails can be divided into dust removal and lubrication maintenance.

How to choose a precision electric sliding table module?

2022-12-13

How to choose a precision electric sliding table module? Precision electric sliding table modules are widely used in active industrial fields and are developed in various active industries. When selecting a linear module, various factors must be comprehensively considered. Here are some key factors to check: 1. Vibration resistance and stability: Stability refers to the ability to avoid self-excited oscillation under given operating conditions; vibration resistance refers to the ability of the precision electric sliding table module to withstand forced oscillation and impact. 2. Stiffness is particularly important for precision machinery and instruments. The deformation of the precision electric sliding table module includes the deformation of the guide rail body, the contact deformation of the guide rail pair, and the ability of the guide rail to resist stress deformation. Deformation can affect the relative position between components and guiding accuracy, and two servo cylinders should be considered. 3. Motion sensitivity and positioning accuracy: The motion sensitivity of the linear guide rail refers to the smallest stroke that the moving parts can complete; positioning accuracy refers to the ability of the moving parts to stop at the specified position as required. Motion sensitivity and positioning accuracy are related to factors such as guide rail type, friction characteristics, motion speed, transmission stiffness, and the quality of moving parts. 4. Accuracy sustainability: This refers to the ability to maintain the original accuracy during operation. The accuracy sustainability of the module mainly depends on the wear resistance of the guide rail and...

Let's talk about how to reinforce a hollow reducer. What are some effective methods?

2022-12-05

Let's talk about how to reinforce a hollow reducer. What are some effective methods? With the continuous advancement of technology, many production industries now pay great attention to the characteristics of equipment and instruments. Because of this, we can provide consumers with trust and protect products, establishing a good brand image. Therefore, it is very important to develop good management and safety methods, and the regulations of hollow turntable manufacturers are also very strict. Many manufacturers need to improve the protection level of hollow reducers to enhance efficiency, reduce assets, and protect products in experimental equipment. Below, I will share effective methods to enhance equipment. 1. The center of gravity for everyone needs to be reinforced. If stainless steel plates and heating are used for specific adjustments, as long as quality protection can be enhanced in one operational cycle, this method applies to using key bearings to enhance output power. This can strengthen the rated power applied to the overall strength of large labor and work, thereby improving the total production and quality. 2. In the application research of general bearings, it is generally necessary to discard them and replace them with precision bearings. This may improve the asset management of enterprises, but the effect has greatly improved. Now, it can reduce noise in production.

What are the reasons for the looseness and leakage of the hollow reducer?

2022-11-23

What are the causes of looseness and leakage in hollow reducers? Hollow reducers are mechanical transmission devices used in many sectors of the national economy, with product categories including various gear hollow reducers, planetary gear hollow reducers, worm hollow reducers, and various specialized transmission devices such as speed-increasing devices, speed-regulating devices, and various composite transmission devices including flexible transmission devices. The service areas include industries such as metallurgy, non-ferrous metals, coal, building materials, shipbuilding, water conservancy, electric power, engineering machinery, and petrochemicals. 1. Leakage occurs Due to the loosening of parts and vibrations, as well as the heating effects of hollow tapered pipes, the sealing surfaces and pipe joints of the hollow tapered pipes may leak. Some defects, such as casting issues, are difficult to detect during assembly and debugging, but due to vibrations and impacts during operation, these defects become apparent, manifesting as oil leakage (seepage). Therefore, occasional leakage may occur during the break-in period. 2. Loosening occurs There are deviations between the geometric shapes and assembly dimensions of newly assembled parts. In the initial usage phase, due to alternating loads from impacts and vibrations, as well as factors such as heating and deformation, combined with excessive wear, it is easy for previously tightened parts to become loose. 3. Many operational errors Due to a lack of understanding of the hollow...

What are the causes of gear shaft wear in hollow reduction gears?

2022-11-14

What are the causes of gear shaft wear in hollow reducers? Hollow reducers are generally used in low-speed, high-torque transmission equipment. High-speed motors, internal combustion engines, or other power sources can engage with a small gear on the input shaft and a large gear on the output shaft through the reducer. However, after years of operation, the gear shafts of hollow reducers inevitably experience wear, which is generally caused by improper operation during use. We all know that quality issues with gears can increase gear wear, but few people know what aspects constitute unqualified gears. Generally speaking, the reasons for abnormal wear of hollow reducer gears are as follows: 1. The material of the forged gear does not meet design requirements, leading to abnormal wear. Gears should be made from materials with high strength, high toughness, and good wear resistance. 2. Poor forging processes can result in defects such as sand holes, gas holes, loose holes, and insufficient surface hardening. A good forging process is very important for gears. 3. If the heat treatment process is poor, the hardness may be insufficient, or if no heat treatment is performed, carburizing and quenching can be used to improve gear hardness. 4. Unreasonable gear design or mismatched gears can lead to failure in achieving the required gear meshing accuracy and motion precision. Only through precise gear design can this issue be reduced.

Introduction to the structural characteristics of precision electric sliding tables, come and collect!

The precision electric sliding table is driven by a motor to automatically move the workpiece in a straight line. By combining multiple directional axes, it forms the motion execution mechanism on the equipment, commonly referred to as industrial robotic arms, XYZ axis manipulators, coordinate axis sliding tables, etc. The main features of the precision electric sliding table can be represented by three main parameters, which are introduced below: 1. Accuracy: Different industries have varying accuracy requirements for electric sliding tables, so there are no specific regulations on the accuracy of electric sliding tables. Accuracy can be classified based on large machine tools and medium to small machine tools. Large machine tools generally have an accuracy of around 1 millimeter, while the accuracy requirements for medium to small machine tools are generally higher than 0.1mm. 2. Speed: The speed of electric sliding tables during use is generally less than the theoretical value, as the speed is mainly affected by the load on the electric sliding table. Additionally, if speed is prioritized during production, accuracy may be compromised and decrease. 3. Load: Load is one of the main factors affecting the accuracy and speed of electric sliding tables. The effective stroke refers to the length of the effective path that the slider on the electric sliding table can move. The longer the electric sliding path, the greater the negative impact of the load. Due to the influence of different specifications on the structural development of electric sliding tables, it is impossible to unify the structure of electric sliding tables. However, they can be divided into external structures and internal structures.

Introduction to the installation method of precision electric sliding tables, come and bookmark it!

The precision electric sliding table, as an active drive component, is generally referred to as a linear module or sliding table module. Among many mechanical active devices, why is the precision electric sliding table widely used in fine motion control? What is its function? Today, I will introduce it to you. First, it is important to know that the role of the precision electric sliding table is to support and guide moving parts, allowing them to move back and forth in a given direction. The positioning accuracy is often much higher than that of general equipment. Therefore, the electric sliding table usually refers to the ball screw drive module. In this structure, rolling steel balls are used instead of the central medium between the moving and fixed components of the linear guide rail. This structure has many advantages, such as low friction, low maintenance workload, and high production capacity. The electric sliding table consists of a slider, ball screw or other drive mechanisms, guide rails, aluminum base plates, and various mechanism components. Through the combination of these units, it can achieve high-precision linear and curved motion with a load, and its accuracy and load capacity can also be effectively guaranteed. This equipment can completely replace cylinders and hydraulic cylinders to achieve the same working functions, thus enabling remote control, centralized control, or active control.

Products for both general environments and harsh working conditions have also been successfully developed. As automation continues to evolve, it will become increasingly intelligent, further liberating productivity and human hands. The precision electric sliding table module, as a fundamental component, will also receive the development and progress it deserves! The precision electric sliding table is a device that obtains driving force through ultrasonic stretching and vibration, and then uses sliding friction to drive the motor rotor.

The characteristics and uses of hollow shaft reducers.

2022-10-13

The hollow reducer is currently a blank space in the market, directly replacing CAM frequency converters and DD motors. The hollow reducer is a digital rotating platform with high positioning accuracy, offering advantages of low cost and high precision, and occupies a strong market position among rotating platforms. The six major uses of the hollow reducer include high precision positioning with varying load inertia, application of inertial loads, high precision positioning with hollow holes, use of hollow optics, and hollow suction. The hollow rotating platform reducer has different stiffness depending on the type of output platform, utilizing different types of bearings. Deep groove ball bearings are used for the 60MM model, while crossed roller bearings are used for the 85MM and 130MM models. The larger the model, the greater the allowable inertial load; conversely, the smaller the model, the lesser the allowable inertial load deviation. Direct connection: The design of the reliable hollow reducer for lifting is simple, allowing for direct installation of the equipment's workbench and robotic arm. When general equipment operates through pulley systems and other mechanical components, the precision of these components is often reduced due to the impact of transmission efficiency, or maintenance of the components may be required. The DG series can be directly installed without intermediate components, allowing for the direct use of the product's own precision while avoiding maintenance troubles. This is achieved by using a segment of the reduction gear mechanism to increase the efficiency.

Classification and Working Principle of Hollow Shaft Reducers

2022-10-10

Overview and Working Principle of Hollow Gear Reducers Hollow gear reducers, also known as speed reducers, are a type of mechanical device that is very simple yet essential. A hollow gear reducer is a gear set that sits between a motor and a machine, used to reduce the speed of power transmission. There are two main purposes for hollow gear reducers: to multiply the torque generated by the power source (input) and to reduce the input speed to achieve a precise output speed. Hollow gear reducers are generally used in low-speed and high-torque transmission system equipment, reducing the speed of power data from motors, internal combustion engines, or other economically high-speed network operations. Ordinary reducers also have several pairs of gears that operate on the same principle to achieve their desired effect. Hollow gear reducers are typically used in low-speed and high-torque transmission systems. The output gear of a hollow gear reducer has more teeth than the input gear. Therefore, while the output gear may rotate more slowly, it reduces the input speed, resulting in increased torque. In summary, the combination of large and small gears increases torque while reducing speed. The ratio of the number of rotations of the driving gear to the driven gear in the reducer structure is called the transmission ratio. By changing the output torque/speed, the machine (usually a motor or engine) can precisely control its speed. The output control torque analysis of the reducer can be...
