CVT PULLEY SHEAVE, module 2, Teeth 21, The gear industry has mature technology, among them, the gear precision refers to the shape of gear integrated error divided by one level, including tooth, tooth, some important parameters such as diameter jump which refers to the radial tooth shape of tooth profile, tooth to refers to the longitudinal tooth shape, diameter jump refers to the distance between the adjacent two tooth error.
Normally we automotive gear can be made of gear hobbing machine processing is completed, 6 ~ 7 magnitude can be used, and some of the printing press due to high speed running and batch printing, so the high precision gear to reduce the accumulated error caused by the gear and make the printing effect to decline, while domestic production of gear grinding machine for processing to 4 ~ 5, imported high precision gear grinding machine for processing to 3, or 4, Some can be processed to level 2. The Japanese standard DIN 0 level is equivalent to level 4 of Chinese evaluation, and the general error is in μm, 1μm=0.001mm.
