Number of teeth: 20 teeth-29 teeth
Outer diameter: 22-31mm
Inner hole: 4-15mm.
Total thickness: about 18mm
Top wire: 2 fixing screw holes M4
Surface: Blackening
Notes:
1. The gear material is 45 steel, and the inner holes are all with a positive tolerance of 0-positive 0.04. There may be a small amount of burrs in the spot, which is a normal phenomenon.
2. The gear surface has blackening treatment and high-frequency quenching treatment, which is the hardness of 45 steel materials. The surface hardness is about 40-45 degrees.
3. 1M 10 teeth-14 teeth Because the effective tooth height is 12mm, the remaining position seems to have teeth, but there is no rolling in place, so the two gears are not suitable for parallel occlusion!
4. The outer dimensions of the gear (except the accuracy of the inner hole) may vary slightly according to different batches.
The contact between the gears is firm, which ensures the normal operation of the machine and good bearing capacity.
Used widely in conveying, hardware, agricultural equipment, printing machinery, automotive applications, mechanical transmission, etc.
