Abstract
The invention relates to a high-voltage motor rolling bearing. A ball bearing and a roller bearing are sleeved on a shaft, a bearing outer cover and a bearing inner cover are respectively installed at two ends of the roller bearing and the ball bearing, the shaft at the outer end of the roller bearing is provided with an oil thrower wheel, and bearing housings are sleeved on outer rings of the ball bearing and the roller bearing. The high-voltage motor rolling bearing is characterized in that: a washer is arranged at the inner ring between the ball bearing and the roller bearing, and a waveform spring sheet is arranged at the outer ring between the ball bearing and the roller bearing. The bearing outer cover, the bearing housing and the bearing inner cover are fixed together by a hexagon bolt and an elastic washer. An oiling pipe and an oil discharging device are arranged on the bearing outer cover. A check ring is arranged between the oil thrower wheel and the shaft. The invention has simple and compact structure and obvious effect; and the waveform spring sheet and the washer are added, and a light series of bearings are selected, thus the service life of the motor is qualified, various performance requirements on the motor also can be met, and the cost of the motor can be reduced.
Description
Technical field
The present invention relates to a kind of rolling bearing, especially a kind of bearing that is used for four utmost points and above high-voltage three-phase asynchronous motor.
Background technology
Motor shaft extension end bearing is selected the main shaft extension end diameter of considering, next considers bearing useful life, in general, shaft extension end diameter of shaft all has regulation in national standard, so each producer when selecting bearing in this unanimity of physa, unique difference is that some producer's selection series is different, such as selection thin that has etc., but the price factor of bearing directly influences the cost of motor, ten times of the price of bearing the chances are motor price, therefore, the assembly structure of the selection of bearing and adaptation bearing just seems more outstanding.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of high-voltage motor rolling bearing that can reduce motor cost is provided.
According to technical scheme provided by the invention, described high-voltage motor rolling bearing, sheathed ball bearing and axis of a cylinder hold on axle, hold with the two ends of ball bearing at axis of a cylinder bearing end cover and internal bearing cover are installed respectively, hold at axis of a cylinder on the axle of outer end and be provided with disc, on the outer ring that ball bearing and axis of a cylinder hold, be arranged with bearing holder (housing, cover); Feature is: the inner ring position between described ball bearing and axis of a cylinder hold is provided with packing ring, and the position, outer ring between ball bearing and axis of a cylinder hold is provided with the wavy spring sheet.
Described bearing end cover, bearing holder (housing, cover) and internal bearing cover are fixed together by hex bolts and spring washer.
On described bearing end cover, be provided with oil fuel tube and discharge equipment.
Utilize retaining ring sealing between described disc and the axle.
The present invention is simple in structure, compact, and action effect is obvious; Under the situation that does not change structural material, under the condition that guarantees motor safety and reliability, by increasing wavy spring sheet and packing ring, select the thin bearing for use, can reach motor useful life, can satisfy the requirement of motor various aspects of performance again, can reduce motor cost again.
