there In this situation, are there many factors that can affect the choice of gearbox? Applications include torque, output shaft radial load, input Output speed, gap, noise, installation layout, and operation Conditions. Considered the following considerations and steps.

torque：

 The torque of the planetary gearbox includes rated output torque, maximum torque, and emergency shutdown torque.

1. Rated torque

usually The planetary gearbox can operate at a load of 20000. Working for several hours at rated input speed without damage.

2. Maximum torque

Also This is called peak torque or acceleration torque. The planetary gearbox can immediately transmit torque. If this is Exceeding the torque may damage the planetary gearbox or The impact on the service life.

3. Emergency stop torque

The torque limit for gearbox design is usually three times the rated output torque.

name Output torque is the most important indicator of exceeding the rated value The output torque reduces the service life or accuracy of the gearbox, Internal components were also damaged. Planetary gearbox The size is usually determined based on the torque parameters listed in the table. Technical specifications. Therefore, it is necessary to choose the appropriate one The size of the gearbox is based on the torque applied to the output shaft.

Radial and axial loads

Radial Axial load is the maximum force applied to the output shaft. Radial and axial. This load comes from Transmission components installed on the output shaft, such as chains Chain wheels, pulleys, belts, gears, and other driving components. Radial and axial loads depend on the strength and stiffness of the structure transmission case& #  39;  Output shaft, bearings, gears, and gearbox. Overload capacity The gearbox and its components are damaged.

Accuracy level

here The accuracy of planetary gearboxes is usually expressed as Tooth clearance is one of the main indicators of planetary gearboxes. The clearance is mainly due to the gap between gears when they mesh, This results in insufficient transmission speed. The level of accuracy is related to the price of the planetary gearbox, and The accuracy depends on your specific application. Requirements for high performance and precise positioning High precision level (low clearance) gearbox. For the following applications Focusing on torque or not requiring high precision, more economical Models can be considered.

Noise

here The noise of the gearbox is related to gear materials, machining accuracy, transmission ratio, etc. D. Gear contact coefficient, clearance, tooth profile, smoothness Tooth surface and operating conditions. Generally speaking, higher levels Reduce noise with precision during operation, tilt gears It is usually quieter than direct transmission. Users can choose the most suitable one According to actual needs.

Transmission adjustment

planet The gearbox can be divided into parallel output shafts (straight) Type and rectangular type. Linear form is more commonly used, but when Due to limited installation space, rectangular type can be chosen. Direct and rectangular gearboxes are available for selection. Shaft or flange output. Both methods can be universal. Transmission components such as gears, pulleys, and chains. Generally speaking, shaft output can meet most transmission requirements. However, when Applications require special large axial or radial forces, flanges You can choose to output to provide higher bandwidth.

Other preventive measures

although Planetary gearboxes are mainly used for automation In many harsh working conditions, such as, High or extremely low temperature, corrosive environment, high dust content Due to its high torque, it has high requirements for IP. Density, stiffness, accuracy, and efficiency. In this situation, especially Materials, protection level, and surface must be considered Processing components, seals, lubricants, and part dimensions Maintain its performance and lifespan in different operations Conditions.
