How to adjust the mounting angle of the precision gear hob?
Jul 11, 2018

How to adjust the mounting angle of the precision gear (grinding) hob? The following small series will explain you in detail.

 

When cutting the helical gear (including the helical gear), the spiral direction of the hob is reasonably selected, which has a certain influence on the precision of the hobbing precision gear.

 

When cutting the teeth, it is desirable that the mounting angle of the hob is smaller (the hob spiral is in the same direction as the cut gear spiral, and the mounting angle is small). Because of this, the hob is in the opposite direction to the machine tool table in the direction of the tangent of the cut gear. That is, the hobbing machine indexing worm has the opposite axial direction of the worm wheel.

 

This can eliminate the gap of the worm wheel pair, and is not easy to cause vibration, thereby improving the cutting precision and reducing the surface roughness. At the same time, the hob can participate in cutting more cutting teeth, the cutting condition is better, and the quality of the cut precision gear is higher.

 

If the mounting angle of the hob is large, the number of teeth participating in the cutting is reduced, the cutting load is concentrated, the teeth are easily worn, vibration is likely to occur, and the quality of the cut precision gear is poor.
