457 Gear

PRODUCT PARAMETERS:

Yiwu heavy truck cylindrical gear is an important part of the mechanical structure, Yiwu heavy truck cylindrical gear used in the helical gear in the truck helix Angle is relatively large, it is the same as the hyperboloid gear, driving smoothness is very good, unlike the old cone teeth that drive only the side torque load, the transfer coefficient is relatively small. The hyperboloid spiral gear 99 of Yiwu heavy truck cylindrical gear moves with both side drive torque and axial spiral torque, which plays a part of the role of worm driving worm gear, and the positive and negative drive of Yiwu heavy truck cylindrical gear is also very free.
