Abstract
The utility model discloses a but motor shaft self -lubricating motor, include motor casing, pivot and set up two roller bearing between the two, roller bearing includes outer lane and inner circle, about two roller bearing each other the symmetry stack place, bearing inner race's shaft hole is passed in and each other laminating of the flange facial features of inner circle, pivot, is equipped with the round oil duct at bearing inner race's flange face, the oil duct inner wall communicates with each other with bearing inner race's shaft hole, there are a plurality of oil grooves along radial opening on bearing inner race's flange, the oil groove communicates with each other with the oil duct, the pivot is a hollow shaft, in the pivot with the bearing inner race flange on oil duct assorted position open and to have a connecting hole, this connecting hole will change epaxial hollow position to be connected with the oil duct on the bearing inner race flange, a formation oil feed passageway. The utility model discloses a but motor shaft self -lubricating motor adopts axle oil feed structure, and the lubricated effect of oil feed is obvious, has avoided the bearing card condition of waiting indefinitely, the cost is reduced.
Description
Technical field
The utility model relates to a kind of motor shaft can self-lubricated motor.
Background technique
The rotating shaft of motor and motor can between be provided with bearing, after long in use, grease meeting approach exhaustion in its bearing, the roller in bearing and retainer is caused to damage like this, bearing is stuck, causes frictional force increase and produce abnormal sound, if carry out the replacing of bearing, the funds that will certainly increase enterprise sharply rise, but also can affect its daily production.
Summary of the invention
The utility model will solve bearing in existing motor due to grease approach exhaustion and cause the stuck and technical problem met accident of bearing.
The technical scheme in the invention for solving the above technical problem is:
A kind of motor shaft can self-lubricated motor, comprise motor casing, rotating shaft and be arranged on two roller bearings between the two, described roller bearing comprises outer ring and inner ring, placement is superposed symmetrically about described two roller bearings, and the rib face of inner ring is bonded to each other, rotating shaft is through the axis hole of bearing inner race, and be provided with a circle oil duct in the rib face of bearing inner race, described oil duct inwall communicates with the axis hole of bearing inner race; The rib of bearing inner race radially has some oil grooves; Oil groove communicates with oil duct; Described rotating shaft is a hollow shaft; The position that rotating shaft matches with the oil duct on bearing inner race rib has an attachment hole, and the hollow part in rotating shaft is connected with the oil duct on bearing inner race rib by this attachment hole, forms axle oil inlet passage.
Hollow axis hole external oil collecting mouth in rotating shaft.
The technique effect that the utility model can reach is:
Compared with prior art, machine shaft of the present utility model is hollow shaft, oil duct and oil groove is driven at bearing inner race, and hollow shaft communicates with oil duct, by realizing the oiling in bearing to oiling in hollow shaft, under the prerequisite without the need to changing bearing, avoid the stuck problem of bearing that in bearing, grease approach exhaustion brings, both ensure that safe handling, in turn save the funds difficult problem that replacing equipment brings.
Accompanying drawing explanation
Fig. 1 is that the utility model motor shaft can the schematic diagram of axle oil-inlet mechanism of self-lubricated motor;
Fig. 2 is that the utility model motor shaft can the schematic diagram in bearing inner race rib face of self-lubricated motor.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1, Fig. 2, the utility model provides a kind of motor shaft can self-lubricated motor, comprise motor casing 11, rotating shaft 1 and be arranged on two roller bearings 2 between the two, described roller bearing 2 comprises outer ring 4 and inner ring 3, described two roller bearings about 2 superpose placement symmetrically, and the rib face 7 of inner ring 3 is bonded to each other, and rotating shaft 1 is through the axis hole 8 of bearing inner race 3, be provided with a circle oil duct 5 in the rib face 7 of bearing inner race 3, described oil duct 5 inwall communicates with the axis hole 8 of bearing inner race 3; The rib of bearing inner race 3 radially has some oil grooves 6; Oil groove 6 communicates with oil duct 5; Described rotating shaft 1 is a hollow shaft; The position that rotating shaft 1 matches with the oil duct 5 on bearing inner race 3 rib has an attachment hole, and the hollow part in rotating shaft 1 is connected with the oil duct 5 on bearing inner race 3 rib by this attachment hole, forms axle oil inlet passage.
Hollow axis hole external oil collecting mouth 9 in rotating shaft 1.
After motor uses a period of time continuously, open the oil nozzle 9 in rotating shaft 1, by oiling equipment toward oiling in the hollow shaft of rotating shaft 1, due to the oil pressure of external oiling equipment, grease enters in the oil duct 5 of bearing inner race 3, after filling grease in oil duct 5, the oil groove 6 that grease with certain pressure intensity begins through bearing inner race 3 rib side is injected in bearing, then oil is filled in whole hollow shaft and bearing, then oil nozzle 9 is covered, when rotating shaft 1 rotates, owing to carrying out rolling friction between the roller 10 in bearing and bearing inner race 3, such roller 10 just can by oil groove 6, grease in oil duct 5 and hollow shaft is piecemeal to be transferred in bearing, reach the object of oiling.
In sum, motor shaft of the present utility model can self-lubricated electric machine structure simple, successful, saves replacement cost, also extends working life.
Above the motor shaft that the utility model embodiment provides can be described in detail by self-lubricated motor, apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment is just for helping to understand the technological scheme that the utility model discloses; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
Claims (2)
1. a motor shaft can self-lubricated motor, comprise motor casing, rotating shaft and be arranged on two roller bearings between the two, described roller bearing comprises outer ring and inner ring, placement is superposed symmetrically about described two roller bearings, and the rib face of inner ring is bonded to each other, rotating shaft is through the axis hole of bearing inner race, and it is characterized in that: be provided with a circle oil duct in the rib face of bearing inner race, described oil duct inwall communicates with the axis hole of bearing inner race; The rib of bearing inner race radially has some oil grooves; Oil groove communicates with oil duct; Described rotating shaft is a hollow shaft; The position that rotating shaft matches with the oil duct on bearing inner race rib has an attachment hole, and the hollow part in rotating shaft is connected with the oil duct on bearing inner race rib by this attachment hole, forms axle oil inlet passage.
