As we know, bearing is an important part of diesel generator set and has a huge influence on the service life of diesel generator set, so what is the requirements of diesel genset bearing? Starlight Power generator manufacturer answers for you. 1.Bearing ring gear Because transmission accuracy of the bearing is low , and diameter of the ring gear and the module of the gear is bigger, the accuracy level of the gear is generally required to be 9 or 10 in GB / t10095.2-2001. However, due to the influence between the pinion and the bearing ring gear in the working state, the tooth surface of the bearing ring gear should be hardened, and the hardness of the pinion tooth surface is generally 60 HRC. Considering the equal life design, the hardening hardness of the gear tooth surface of the large gear is specified as no less than 45 HRC. 2.Clearance Yaw and pitch bearings have special requirements on clearance. Compared with the yaw bearing, the impact load of th...
