The tooth height of CVT PULLEY SHAFT is 2 and the tooth width is 36, The tooth height of CVT PULLEY SHAFT is 1 and the tooth width is 35,

Failure modes of gears:

1, tooth surface wear

For open gear drive or closed gear drive containing dirty lubricating oil, due to the relative sliding between meshing tooth surfaces, some hard abrasive particles enter the friction surface, so as to change the tooth profile and increase the backlash, so that the excessive thinning of the gear leads to tooth fracture. In general, only when the lubricating oil is mixed with abrasive particles, it will cause abrasive wear on the tooth surface in operation.

2. Tooth surface bonding

For high-speed and heavy-load gear transmission, due to the large friction between tooth surfaces, the relative speed is large, resulting in high temperature in the meshing area, once the lubrication condition is poor, the oil film between tooth surfaces will disappear, making the metal surface of the two teeth contact directly, so as to bond with each other. When the two tooth surfaces continue to move relative, the harder tooth surface will be softer tooth surface along the sliding direction of part of the material torn down to form grooves.
