What are the factors associated with the heating of tapered roller bearings?
2, assembly, because the inner and outer ring of tapered roller bearings in the assembly before the separation, not finished or not, compared with other bearing, the requirement on assembly is especially high, the assembly process to avoid roller deformation, not with the percussion assembly, pay attention to the position of the outer ring and the bearing shaft must meet the manual requirements note that in accordance with the actual conditions to adjust the preload of the bearing assembly, ensure qualified clearance.3, lubrication way is not correct, high-speed running bearings on lubrication requirements are very high, if the corresponding improper lubrication, it is easy to cause the temperature rise, and even burned bearings.In fact, the general situation of temperature rise is not too big problem, especially when the temperature rises to a certain value can be stabilized, there will be no big problem.
The use of bearings and assembly is a very systematic project. There are many reasons for bearing heating, but we can consider the following aspects:1, design reasons, the use of speed exceeds the maximum speed of bearing or maximum load. Because the ball and tapered roller bearing raceway is line contact, compared with ball bearings, his bearing is very high, but the corresponding, the line speed is much smaller, can check to see whether the manual selection of bearings within the scope of its work.
Poor lubricationThe oil gap is too smallThere is no ultra fine racewayExcessive speedThe cooling condition is too badetc.
