Description
Technical field
The present invention relates to reductor technical field, more particularly to a kind of reductor bearing forced lubrication structure.
Background technology
It is well known that machine operation is required for being lubricated using oil or grease, reductor is no exception, and some subtracts
Fast machine scene can not arrange that Lubricating-oil Station just can only rely on self-lubricating, and due to the reasons such as reductor placement location, some internal teeth
Wheel or bearing can not obtain abundant splash lubrication, therefore need extra oil supply to be lubricated.
In the past, two bearings are provided with reductor, in hollow shaft, outside sets a bearing, two in hollow shaft
Bearing touch can not realize lubrication less than lubricating oil.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided a kind of reductor is forced with bearing
Lubrication system.
The technical solution adopted for the present invention to solve the technical problems is：A kind of reductor bearing forced lubrication structure,
Including casing and hollow shaft, the hollow shaft is rotatably arranged in casing, and clutch shaft bearing, the sky are set outside the hollow shaft
Second bearing and 3rd bearing are provided with mandrel, the hollow shaft has the shaft shoulder, and the second bearing and 3rd bearing are located at
On the inside of the hollow shaft shaft shoulder, the clutch shaft bearing is located at hollow shaft shaft shoulder upper end；
The hollow shaft shaft shoulder opens up fuel feed hole, and the hollow shaft shaft shoulder is socketed with into oil ring, the fuel feed hole be located at into
On the inside of oil ring, the fuel feed hole of the shaft shoulder connects with entering oil ring inner chamber, it is described enter oil ring inner chamber connect oil inlet pipe, the oil inlet pipe
It is connected through casing with outside oil pump.
Further, upper isolating ring and lower isolating ring are respectively sleeved in the hollow shaft of the clutch shaft bearing upper and lower ends, it is described
Lower isolating ring is shelved on shaft shoulder upper end, and the lower isolating ring is located at into oil ring upper end, and the lower isolating ring limits to move on oil-feed ring, institute
State upper isolating ring upper end and locking nut is set, the locking nut is screwed in hollow shaft, and the locking nut is screwed first axle
Hold and be fixed on outside hollow shaft.
The beneficial effects of the invention are as follows：
1st, this lubrication system just additionally need not periodically take maintenance apart in assembling once installation, need to only follow reductor to tie up
Shield.
2nd, design of part is simple, does not influence remaining parts normal operation.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is reductor bearing forced lubrication structure schematic diagram；
Wherein, 1, casing, 2, hollow shaft, 3, clutch shaft bearing, 4, second bearing, 5, fuel feed hole, 6, enter oil ring, 7, oil-feed

Embodiment
Presently in connection with specific embodiment, the present invention is further illustrated.These accompanying drawings be simplified schematic diagram only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of reductor bearing forced lubrication structure, including casing 1 and hollow shaft 2,2 turns of hollow shaft
It is dynamic to be arranged in casing 1, clutch shaft bearing 3 is set outside hollow shaft 2, second bearing 4 and 3rd bearing are provided with hollow shaft 2, it is empty
Mandrel 2 has the shaft shoulder, and second bearing 4 and 3rd bearing are located on the inside of the shaft shoulder of hollow shaft 2, and clutch shaft bearing 3 is located at the shaft shoulder of hollow shaft 2
Upper end.
The shaft shoulder of hollow shaft 2 opens up fuel feed hole 5, and the shaft shoulder of hollow shaft 2, which is socketed with into oil ring 6, fuel feed hole 5, to be located at into oil ring 6
Side, the fuel feed hole 5 of the shaft shoulder connect with entering the inner chamber of oil ring 6, enter the inner chamber of oil ring 6 connection oil inlet pipe 7, oil inlet pipe 7 is through casing 1 and outside
Portion's oil pump connection.
Upper isolating ring and lower isolating ring 8 are respectively sleeved in the hollow shaft 2 of the upper and lower ends of clutch shaft bearing 3, lower isolating ring 8 is shelved on axle
Shoulder upper end, lower isolating ring 8 are located at into the upper end of oil ring 6, and lower isolating ring 8 limits to move upwards into oil ring 6, and upper isolating ring upper end sets locking screw
Mother 9, locking nut 9 is screwed in hollow shaft 2, and locking nut 9, which screws, is fixed on clutch shaft bearing 3 outside hollow shaft 2.
During operation, hollow shaft 2 rotates, lubricating oil by oil inlet pipe 7, enter oil ring 6, fuel feed hole 5 enter hollow shaft 2 in,
Lubricate second bearing 4 and 3rd bearing, be fixed structure between oil inlet pipe 7 and casing 1, oil inlet pipe 7, enter oil ring 6 and casing 1 it
Between geo-stationary, relatively rotated with hollow shaft 2, three bearings are used to aid in hollow shaft 2 to rotate, and make its rotation more steady.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
