The process flow of sprocket as below:
This sprocket is used for Bulldozer, material is 50Mn or 45SIMN, the hardness is about HRC55-58, having wide choice range, the sprocket is applicable to special model of crawler type excavators and bulldozer from 0.8T-100T, it is widely applied in bulldozers and excavators of Caterpillar, Komatsu, Hitachi, Kobelco, VOLVO, Hyundai, Daewoo etc, adopts precision processing technology and special heat treatment technique, so reach the best wear-resistance and prolong life time to maximum extent. The cause of driving wheel block and broken teeth 1. There are problems in casting and heat treatment of the driving wheel; 2. The material strength does not meet the quality standard; 3. The driving wheel is too soft or too hard, resulting in deformation or brittle hard block; 4. The driving wheel structure design is not reasonable, resulting in local stress concentration.
