Description

Gearbox Pulley Basic Technical Parameter:

 

Specification of  gearbox pulley:
The diameter and other dimensions of the pulleys of various types of mechanical equipment are all matched according to the reduction ratio, and they are designed by the working speed and the speed of the motor.

SDT gearbox pulley from sdtgear.com

SDT gearbox pulley, groove number from 1 to 8 .

 

Working speed/motor speed = driving wheel diameter / driven wheel diameter * 0.98 (sliding factor), such as the belt pulley using steel material, the linear speed is not required to be higher than 40m / s if the material uses cast iron, the linear speed is not higher than 35m / s.
The pulley must produce various grooves according to the shape of the triangle belt; these different grooves determine the O-type pulley, A-type pulley, B-type pulley, C-type pulley, D-type pulley, E-type pulley, etc. model.
The Chinese national standard stipulates that the models of the V-belt are O, A, B, C, D, E, and F. The corresponding pulley wheel groove angles are three kinds of 34 °, 36 °, and 38 °. The minimum diameter of the small pulley corresponding to each type of groove angle is not specified for the large pulley. The groove angle of the pulley is divided into 32 degrees, 34 degrees, 36 degrees, and 38 degrees. The specific choice depends on the groove type and the reference diameter of the pulley;
