Gear motor is generally called gear motor immediately. For the new gear reducer, gear is an indispensable transmission part. Equipped with good gear can improve the mechanical equipment of gear motor, which can not only improve the transmission efficiency, but also make the transmission more stable. However, we found that the gears in gear motors are basically helical, and spur gears are rarely used. Why?

According to the comparison of helical gear and spur gear in gear motor, it can be found that the position of helical gear is relatively casual. In the case of using helical gear, the transmission shaft of differential of double shaft reducer and rear tire of gear motor may not have a horizontal position, but if using spur gear, then that position is vertical as far as possible. Compared with the straight gear, the coincidence degree of the helical gear motor is larger, and the number of teeth entering the meshing is also large, which can drive with high speed and load. In the production and processing operation steps, the capacity of the speed reducing motor with helical gear should be more refined, which is convenient for everyone to install and move.

Helical gear has low noise. According to the comparison of helical gear transmission ratio, the noise from DCY gear reducer is much lower. The key is that the whole process of helical gear in contact is contact force, surface contact and contact force, and the butt joint is smooth, while the spur gear belongs to line surface contact. Compared with helical gear, the reliability of spur gear motor is not good, and the noise is relatively large in operation. In the operation process, there are many difficulties, so the vast majority of gear motor uses helical gear.
