Worm Reducer

A worm reducer, also known as a worm gear reducer, is a type of gearbox that is used to reduce the speed and increase the torque of a rotating shaft. It is made up of a worm, which is a screw-shaped gear, and a worm wheel, which is a ring with teeth that mesh with the worm. As the worm turns, it drives the worm wheel forward, which in turn reduces the speed and increases the torque of the output shaft.

What are the precautions when connecting the reducer with the motor?

Several aspects that should be paid attention to when connecting the reducer and motor: there are several ways to connect the reducer and motor, such as direct connection, that is, the flange plate is directly connected to the motor, or the belt pulley or coupling can be used.Our worm gear reducer is directly connected with the synchronous motor. We provide you with supporting products, which can also be customized according to your needs

What are the precautions when connecting the reducer and the motor?

  • Allowable input shaft diameter:
    The input shaft hole of the reducer and the output shaft of the motor are generally connected by a sleeve ring with variable thickness. When no collar is added, the input shaft hole of the reducer is large.
  • Large input speed:
    The high input speed of the motor shall be less than the large input speed of the reducer
  • Rated output torque:
    After the rated output torque of the adaptive motor is multiplied by the reducer reduction ratio, the output torque of the reducer shall be less than or equal to the rated output torque of the reducer.
  • Allowable input flange:
    It shall not be greater than or less than the standard size of the primary reducer. For example, the standard flange of the reducer PLE80 is 80mm, and the primary reducer is PLE60 and PLE120. The allowable flange of the PLE80 shall not be less than 60mm nor more than 120mm

Select the reducer model after meeting the main data. The reducer with a small outer diameter can be equipped with a motor with a large outer diameter. On the contrary, a suitable connecting flange can be selected to ensure the correct connection between the motor and the reducer

Synchronous Motor

Synchronous motor is an AC motor that rotates at synchronous speed with torque generated by interaction between DC supplied excitation magnetic field and armature rotating magnetic field.

Synchronous motor is an AC motor, which generates torque through the interaction of the excitation magnetic field provided by DC current and the rotating magnetic field of the armature, and rotates at synchronous speed.) It is an AC motor, which generates torque through the interaction of DC excitation magnetic field and armature rotating magnetic field, and the armature rotates at synchronous speed.
The synchronous motor drives the gearbox to rotate, thus driving the equipment to operate
