Sliding injection system, wherein injection system includes: the oil filling pipeline (6) and oil outlet pipe (9) of plain bearing (1 ') in Fig. 2, oiling
Device (10) and oil discharging device (11) further include the oil sealing (12) that many places are arranged in.In actual use, main maintenance
Work is exactly to give the bearing of motor (1) oil injecting lubricating, needs 30~50 grams/times of oiling within every 1000~3000 hours.In coal mine
In the operation of lower adverse circumstances, the complexity of injection system structure is inconvenient, can not quantify.Gross data and actual conditions are difficult
With consistent, ideal maintenance effects can not be reached.Cause bearing fault to take place frequently, reduces actual life and the use of motor
Effect.In addition motor, which occasionally has, occurs rotor axial impact, causes damage of the bearing, easy oil leakage at axle envelope finally causes bearing to scrap.
Need to pay biggish the cost of manual maintenance and Material Cost in the life cycle management of motor, whens maintenance shut-downs will cause life again
It produces and stagnates, influence production task, bring direct economic loss.Therefore it is badly in need of designing a kind of without shutting down oiling and bearing mounting structure
Simplified New-type electric machine.
Summary of the invention
It is a kind of without shutting down oiling, reducing artificial and Material Cost non-maintaining motor the purpose of the present invention is designing.
In order to achieve the above object, the present invention provides a kind of non-maintaining mining development machine motor, including casing, setting in institute
The rotor for stating the stator of casing internal, being arranged in outside shaft and rotating in the stator, the both ends of the shaft are by exempting from
Maintenance bearing is fixed on the two sides of the casing；
The two sides of the casing are respectively equipped with an inner cover；
The non-maintaining bearing is mounted in the inner cover by the bearing holder (housing, cover) of outside setting, and the non-maintaining bearing
It is fixedly connected on the bearing holder (housing, cover) by outer cover.
Preferably, junction is equipped with washer between the outer cover and the bearing holder (housing, cover).
Advantages of the present invention: complicated oiling and sealing oil system are eliminated, Leakage, assembly environment adaptability are eliminated
It is good；Lubricating grease resistance and oil sealing friction are eliminated simultaneously, improve motor bearings temperature rise；Motor no longer generates waste oil, solves
It handles the problem of environmental pollution of waste grease, reduce expense.Electric machine structure is simplified, easy to produce and maintenance improves electricity
The reliability of machine.Make motor within non-maintaining bearing validity period (generally 9000~27000 hours) from attended operation, even if
Chance failure occurs for bearing, also being capable of quick-replaceable in a short time.Motor can be continuously run, and be avoided because motor stopping misses
The loss of work bring, has high efficiency-cost ratio.The material and structure of non-maintaining bearing are better than plain bearing, Selection of Bearings Merck KGaA
The non-maintaining bearing series of IMROK, general plain bearing material are bearer ring GCr15, rolling element GCr15SiMn.It can preferably support
The axial impact of anti-rotor, the problem of alleviating rotor axial direction impact injury bearing to a certain extent.Relative to
Using the cost of non-maintaining bearing, the production and application cost of motor is reduced.Reduce actual use in manual maintenance at
Sheet and Material Cost.
