Note:

1. n1 is the number of lubricating oil holes, evenly distributed: oil cup M10 × 1 JB/T7940.1-JB/T7940.2

2. Installation hole n-Φ can be replaced by screw hole; Tooth width B can be changed to H-h.

3. The circumferential force of the gear in the table is the maximum circumferential force, and the rated circumferential force is 1/2.
