Introduction to Precision Helical Gear Judgment and Copying Methods

Judging replication method: Along the axis of the helical gear, looking towards the direction of the external helical gear development, the helix forms a diagonal line from the bottom left corner to the top right corner, that is, the direction of clockwise movement; The opposite is also true.

The helical gear has a compact center distance and can withstand high-speed loads. The helical gear reducer is a new type of reduction gear. It has a compact structure, light weight, high transmission torque, smooth starting, small transmission ratio, and can choose any connection method and multiple installation positions according to user requirements.

The larger the helix angle and the greater the overlap, the more conducive the movement is to reducing quietness and noise, and either side will bring a larger helix angle, which depends on the size, machining quality, and machining accuracy of the helix. Yes, a typical tap is 8-25. Yes, in some cases, tap values may be higher when there are special noise requirements.

Axial force distribution is not conducive to gear transmission, increases friction between equipment, and is prone to wear or damage to equipment. The main drawback of helical gears is that they produce axial components when engaged. On the other hand, axial force is caused by the helix angle, and the larger the helix angle, the greater the axial force. When designing diagonal gears, excessive axial force will not be generated.
