Torque Calculation:
The lifetime of a gearbox is greatly influenced by torque calculation. It’s crucial to consider that the acceleration torque (tp) exceeds the maximum load torque of the gearbox. The applicable power is usually the servo model's applicable power in the market. The adaptability of the gearbox is high, and the service factor can generally be maintained above 1.2, but selection can be based on individual needs:
A. The output shaft diameter of the servo motor should not be larger than the output shaft diameter on the workbench.
B. If the torque calculation is normal and the speed meets normal operation, but the servo motor is insufficient for full output, it is necessary to implement current limiting control on the motor side or torque protection for the mechanical shaft. This is important.
The selection process for general gearboxes involves the following steps:
- Propose the initial conditions.
- Select the type.
- Determine the specifications.
In comparison, the selection process is relatively simple. The key to choosing the correct and reasonable specifications for a general gearbox is to provide the working conditions for the gearbox and understand the design, manufacturing, and operational characteristics of the gearbox.
Selecting Specifications Based on Strength, Heat Balance, and Axial/Radial Load Conditions:
Choosing the right planetary gearbox will make the gearbox operate more smoothly in practice and ensure its service life. Planetary gearboxes are known for their small size, high transmission efficiency, wide reduction range, and accuracy. They are widely used in servo, stepper, DC, and other transmission systems.
