The four major series of gear servo WPWDKV155,WPWDKV175,WPWDKV200,WPWDKV250 planetary reducers are the R series, K series, F series, and S series, which are the most commonly used four types of gear servo planetary reducers. It has a long application time and a wide range of applications, playing a crucial role in the gearbox industry. Below, the editor will explain the connection methods between the four series of servo planetary reducers and motors:
Generally speaking, when customers purchase four series of servo reducers, they will purchase them together with the motor. At this time, production is usually arranged by directly connecting the motor and reducer. The reducer interface is a standard interface, and the motor interface is made into non-standard sizes according to the reducer standard (standard motor sizes cannot be directly connected to the reducer), and then directly connected and assembled.
Another option is to have the motor unchanged and equipped with a motor flange that is connected to the servo reducer. This situation is usually used when customers have special requirements and order non-standard products.
Suggest that those that can be directly connected should be directly connected, which is more stable than those connected with flanges.
The most basic requirements for selecting a servo reducer are as follows:
1. Installation size: refers to the size of the front end of the servo motor. When selecting a planetary reducer, the input end of the planetary reducer must fully match the size of the output end of the servo motor.
2. Reduction ratio: Rated output revolutions per minute of the motor/reduction ratio=how many revolutions per minute the reducer outputs. Planetary reducers should choose a reduction ratio as close to the ideal as possible to ensure the desired speed is achieved.
3. Torque: The rated output torque of the servo motor (the stepper motor maintains torque) * the reduction ratio. The rated output speed of the reducer must be greater than this value. If it is less than this value, the reducer may shorten its service life, and in severe cases, the shaft may break or teeth may collapse.
4. Return clearance: Return clearance (accuracy) → (The output shaft of the planetary reducer is divided into 360 degrees, one degree=60 arc minutes), which is commonly referred to as "arc minutes", unit: arcmin. The smaller the return gap, the higher its accuracy and cost. Users can choose a gearbox that meets their accuracy requirements. Also consider lateral/radial forces and average lifespan. Servo planetary reducers with large lateral/radial forces have relatively high reliability in installation and use, and are not prone to problems. Usually, its average lifespan far exceeds the lifespan of the equipped servo motor.
