Where is an expert to know how the roller of deep groove ball bearings fit into the bearing sleeve? Has been very confused!!
4, small amount of interference in the case, at room temperature can be used to suppress sleeve bearing ring face, beating with a hammer sleeve, the sleeve will be pressed into the ring balance. If installed in large quantities, the hydraulic press can be used. When pressing, the outer end surface of the outer ring and the outer shoulder of the shell face shall be ensured, and the inner ring end face is tightly pressed with the shoulder end of the shaft platform, and no gap is allowed.5, when the interference is large, the oil bath heating or inductor heating bearings can be used to install the heating temperature range of 80 degrees -100 DEG C, the maximum can not exceed 120 degrees centigrade. At the same time, the nut or other appropriate method is used to fasten the bearing so as to prevent the contraction of the bearing in the direction of width and to create a gap between the collar and the shaft shoulder.6, the installation should be carried out after the rotation test, the first for the rotary shaft or bearing box, without exception, then the power for no load, low speed operation, and then gradually increase as the functioning of the rotation speed and load, and to detect noise, vibration and temperature, abnormal, stop operation and check. The running test is normal and can be used before delivery.
1. Must be installed in a dry, clean environment. Before installation, the machining quality of each part should be carefully inspected. All mating surfaces must be carefully cleaned and removed, and the cast surface must be clean.2, before installation, should be cleaned with gasoline or kerosene, dry after use, and ensure good lubrication, bearings generally grease lubrication, oil lubrication can also be used.3, the installation must be in the circumference of the end of the ring to apply equal pressure, the ring into the press, shall not be directly hit with tools, so as not to damage bearings.
Hey, there are ideas, this year I asked a very experienced teacher to me, he said the method still use the method of thermal expansion and contraction can be related to large and small, the inner and outer side of first contact with the other side, there is space into the deep groove ball bearing ball. There is only a limited number of ball, unfillable, for more than six, the first few are not a problem, the last one is the most troublesome, only the first five balls on the same side of the other, then the other side of the inner ring and the outer ring contact, so there is a lot of space to put a ball into the final, which may cause the elastic deformation of the ball, after the last loading in the fixed frame, the fixed position of the ball
