Helical cylindrical gear transmission is superior to straight gear transmission, and can be used in high-speed and heavy-duty situations with tight center distance. Helical gear reducer is a new type of reduction transmission device. The optimized and advanced modular combined system design concept has the advantages of small volume, light weight, large transmission torque, smooth start, fine transmission ratio classification, etc., and various installation positions can be connected and selected at will according to user requirements.
Extended data:
The greater the helix angle, the more the coincidence degree, which is more conducive to smooth motion and noise reduction. Everything has two sides. Although increasing the spiral angle brings many benefits, the axial force also increases during machining, so it depends on the quality requirements of the workpiece and the machining accuracy. In general, if there are special requirements, the value of noise 8-25 is larger.
Axial force is harmful to gear transmission, which increases the friction between devices and makes the devices easy to wear or damage. The main disadvantage of helical gears is that they generate axial components when meshing. The axial force is caused by the helix angle. The greater the helix angle, the greater the axial force. In order to prevent the helical gear from generating excessive axial force, it is generally set to = 8 ~ 15 in design.
