Tips: Difference between a 45 teeth ratchet and a 72 teeth ratchet

What are differences between a 45 teeth ratchet and a 72 teeth ratchet? The force tolerance of two types of teeth is different, and the ratchet have different material requirements and different characteristics.

1. Different force tolerance.
45 teeth ratchet are better than 72 teeth ratchet. With fewer teeth, the force-bearing area is larger, and the occlusion area between the teeth and the pawl is larger.

2. Different material requirements.
The 72 teeth ratchet have high requirements on the material. The high density of the teeth facilitates the verification of the ratchet.

3. Different characteristics
45-tooth ratchet features: short-tooth gear addendum coefficient 0.8, head clearance coefficient 0.3; short-tooth gears can adopt a larger positive displacement, so that the minimum number of gear teeth can be reduced (less than 17 teeth), and It will not cause the tip of the tooth to become sharp, undercut, etc., but it will reduce the coincidence coefficient of the gear mesh.75-tooth ratchet wrench features: addendum height coefficient 1, head clearance coefficient 0.25.

However, the torque is the same. The number of teeth should refer to the number of teeth of the ratchet on the head of the wrench. 72 teeth and 45 teeth have no effect on the torque value.
