Zhongyuan Bearing introduces you to bearing bearing pressure

The so-called bearing pressure is the bearing load of the bearing, the bearing load of the huge load divided by the pressure area, the so-called pressure area, when the bearing is cylindrical, take the bearing area of ​​the bearing contact area of ​​the projected area. According to experience, the influence of the sliding speed V on the rise of the friction surface temperature is much greater than the bearing pressure P. The heat generated by the speed V bearing is mainly caused by the friction of the bearing. Therefore, the life of the bearing is mainly determined by the value of P×V. To deal with the ring gear of the casing excavator bearing, first use a steel chisel to cut all the small broken tooth pieces (chips) that have not been detached from the ring gear, carefully clean it, and then use a portable electric angle grinder to grind the fracture. Chamfering to minimize the amount of swarf that may be generated on the broken surfaces of broken teeth; using a hand-held electric mold grinder to carefully grind the surface of the damaged tooth surface due to the intrusion of the broken teeth to ensure its surface There is a good contact surface with the planet wheels. After all tooth surfaces are smoothed with emery cloth. If conditions permit, a better method is to repair the fractured tooth tip with a suitable welding rod, then use an angle grinder to polish it, trim it, and correct the tooth profile to ensure smooth meshing between the ring gear and the planet gears. .
