Description
Technical Field
The invention relates to the technical field of rolling bearing structures, in particular to a liquid oil lubrication rolling bearing structure for an electric motor. The bearing structure commonly lubricated by grease in the prior art is improved to a structure lubricated by liquid oil.
Background
The large and medium-sized high-voltage motor bearing is an important device for mechanical transmission, and the good lubrication of the bearing can effectively reduce noise and vibration acceleration, prolong the service life of the bearing and reduce the maintenance and replacement frequency of the bearing.
At present, all the prior large and medium-sized high-voltage motor bearing lubricants adopt universal lithium-based grease, a bearing inner cover, an outer cover and an oil baffle disc type oil thrower are adopted in a bearing assembly device, grease is accumulated in an inner cover oil cavity, grease accumulated in the inner cover oil cavity can be extruded out of a uniform track in bearing operation, the grease accumulated in the inner cover oil cavity is viscous, and an external forced oiling system is not added, so that the bearing cannot obtain continuous lubricant, an effective oil film cannot be formed, the bearing cannot be effectively protected in operation, intermittent abnormal noise occurs, the abnormal noise is generated along with the increase of vibration acceleration, and under the condition, the abnormal noise only needs to be filled with the grease by a filling oil gun, but the abnormal noise disappears again in 3-4 hours, and the phenomenon repeatedly happens. Due to the characteristics of the materials of the bearing assembly parts, the bearing assembly parts are not displayed and can not be seen in the grease filling process, so that more grease is extruded and leaked into the stator shell by frequent grease filling, serious pollution is caused to the winding coil of the motor, more grease can not be discharged and accumulated in the bearing, and the temperature rise of the bearing is kept high (about 45 ℃ under normal conditions and about 67 ℃ under normal conditions) due to the fact that more grease is not discharged and accumulated in the oil cavity of the outer cover. The common mode of bearing lubricating grease and filling lubricating grease can not meet the lubricating requirement in the running and using process of the bearing, so that the problem that the abnormal noise and the large vibration acceleration of the bearing are large can not be effectively solved.
Vibration data are detected according to maintenance of the motor, and generally only two vibration speeds (mm/s) and vibration amplitudes (mu m) are detected. But with the upgrade and reconstruction of the control system and the practical requirements of users, the monitoring of abnormal sound and acceleration of the bearing is particularly concerned. The abnormal sound of the bearing is a main cause of the large acceleration.
The abnormal sound of the bearing is mainly generated by the fact that good lubrication cannot be obtained in the running process of the bearing, and the fact that the residual quantity of lubricating grease in the rolling bodies and the track of the bearing (particularly the bearing with the rolling elements being rollers) is small is easily found in the motor maintenance, and most of lubricating grease is extruded out of the track in the running process, so that an oil film cannot be formed, and the rolling elements are fully and effectively protected.
In the past, the problem is solved, firstly, grease is continuously filled when abnormal noise exists, secondly, the bearing is replaced when the problem cannot be effectively solved after long-time oiling, the bearing replacement frequency is generally 6 months in turn, 3 months in severe cases and 1 year in the longest. The two solutions have the defects that the temperature of the oil added is 20-30 ℃ higher than the normal temperature of about 45 ℃ by more bearings, the oil cannot be discharged in time and can be extruded into the stator shell, the winding coil is polluted, the winding coil of the motor is aged rapidly, local insulation aging breakdown is caused by serious equipment damage, and the production is stopped.
