Abstract
The invention discloses an end cover for a high-power small-sized asynchronous traction motor. The end cover comprises a bearing outer cover, an end cover, an oil injection channel and an oil draining channel, wherein the bearing outer cover and the end cover are connected integrally; the oil injection channel and the oil draining channel are embedded into an end cover arm, and are sealed together with a bearing housing through oil grooves. The end cover disclosed by the invention is compact in structure, and occupies a small space in the motor. The oil injection channel and the oil draining channel are embedded, so that the functions of injecting oil and draining oil can be realized without detaching to maintain a bearing, and operation becomes easy. By adopting the end cover, the service life of the bearing can be prolonged. Meanwhile, the end cover has high airtightness, the oil injection maintenance process of the bearing is simplified greatly, and the labor force and cost are saved.
Description
Technical field
The invention belongs to vehicle traction field, relate to a kind of high power small size asynchronous traction motor end cap.
Background technology
Traditional electric motor end cap, mainly play the effects such as spring bearing, sealed electric-motor and buffering absorbing, and for motor cavity space is increased, prevent that it from contacting with coil, traditional electric motor end cap is designed to convex, this kind of structure increased inner space and the volume of end cap, also increased the volume of motor.
Vehicle traction to the power of motor, volume, bear vibrations and shock loading etc. has stricter requirement, this just requires end cover structure compact, existing motor oiling is from bearing end cover process end cap and coordinates an oil inlet passage of formation with internal bearing cover, from bearing end cover, discharge again, complicated operation, cannot meet the requirement of vehicle traction motor special to end cap.
Summary of the invention
In order to overcome above-mentioned not enough problem, the invention provides a kind of high power small size asynchronous traction motor end cap, this end cover structure is compact, and volume is little, without dismounting, can realize oiling and oil extraction function to safeguard bearing.
The technical scheme that the present invention adopted is for achieving the above object: a kind of high power small size asynchronous traction motor end cap, comprises bearing end cover and end cap, the integrated connection of bearing end cover and end cap; Also comprise oiling passage and oil drain passage, described oiling passage and oil drain passage embed in end cap arm, and itself and bearing chamber pass through oily ditch seal.
The invention has the beneficial effects as follows: end cover structure of the present invention is compact, the volume that takies motor is little, the embedded oiling of the present invention and oil drain passage, without dismounting, can realize oiling and oil extraction function to safeguard bearing, and easy operating, application the present invention can promote the useful life of bearing, simultaneously, good airproof performance of the present invention, has greatly simplified the process that bearing oiling is maintained, and has saved manpower and cost.

Wherein: 1, oil duct, 2, oiling passage, 3, oil drain passage.
Embodiment
By drawings and the specific embodiments, the present invention is further described.
Embodiment 1
As shown in Figure 1, a kind of high power small size asynchronous traction motor end cap, comprises bearing end cover and end cap, the integrated connection of bearing end cover and end cap; Also comprise oiling passage 2 and oil drain passage 3, described oiling passage 2 and oil drain passage 3 embeds in end cap arms, and it seals by oil duct 1 with bearing chamber is interior.
Its oiling maintenance bearing process is as follows:
Described end cap is arranged on motor, under the cooperation of internal bearing cover, by oiling passage 2, lubricating grease is noted into bearing chamber, new lubricating grease constantly pours in, and old grease is constantly discharged along oil drain passage 3.
By oiling passage 2 and oil drain passage 3 are set, while avoiding bearing maintenance, need dismantle the problem of end cap, oiling passage 2 and oil drain passage 3 adopt oil duct 1 sealing, have improved the environment of bearing chamber, have increased the useful life of bearing.
As shown in Figure 2, the whole plane form that adopts of electric motor end cap, bearing chamber is outstanding, when end cap coordinates with the support of motor, the redundant space that bearing chamber can abundant sharp motor internal, thus make electric machine structure compactness, also optimized the outward appearance of motor.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and the design of exploitation thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
Claims (1)
