Abstract
The utility model relates to a bearing structure of motor shaft. The motor shaft is supported on the oil-retaining bearing, the oil-retaining bearing is arranged in a bearing chamber of the motor end cover, a bearing gland is buckled and pressed on the outer side of the motor end cover, the bearing gland is fixedly connected with the motor end cover, a bearing elastic sheet is arranged in a cavity enclosed by the motor end cover and the bearing gland, an elastic claw of the bearing elastic sheet is tightly pressed on the oil-retaining bearing, and the bearing elastic sheet is fixed on the bearing gland. The utility model provides a problem that high temperature resistant grease fibre volume is too little in the bearing gland, prolonged oil bearing's life. In addition, the bearing chamber of the utility model is of a V-shaped structure, the spherical oil-containing bearing is in line contact with the bearing chamber, and the problems of vibration and noise caused by poor concentricity of the common oil-containing bearing structure are solved; in addition, grease fiber filled in the bearing gland makes the high temperature resistant oil circularly move due to friction between the spherical oil bearing and the shaft when the motor rotates, and the problem of axial oil leakage of a common oil bearing structure is solved.
Description
Technical field
The utility model is a kind of supporting structure of motor shaft, belongs to the renovation technique of the supporting structure of motor shaft.
Background technology
It is cheap that oiliness bearing is compared rolling bearing, oiliness bearing is applicable in the less demanding fan motor of service condition, so fan motor has more and more adopted oiliness bearing, but at present domestic owing to be subjected to the horizontal constraints of bearing arrangement design and manufacturing process, cause occurring that oiliness bearing structure concentricity is bad, motor oscillating and noise greatly, the situation of axial leakage of oil appears in the oiliness bearing structure.In addition, plain bearing airframe bearing gland places the inboard, because the influence of electric machine structure or electrical safety distance, bearing gland designs smallerly, and it is fewer to store the high temperature-resistant grease fiber in the bearing gland.So that often cause having shortened greatly the useful life of oiliness bearing because of the grease deficiency.Or strengthen because of spherical oiliness bearing oil starvation so that with the friction of motor shaft and to cause that motor is stuck can not to rotate.
The utility model content
The purpose of this utility model be to consider the problems referred to above and provide a kind of when guaranteeing the running of oiliness bearing and motor shaft the concentricity height, effectively prevent the axial leakage of oil of motor shaft, the supporting structure of motor shaft that prolongs the useful life of oiliness bearing.The utility model is reasonable in design, easy to use, long service life.
The technical solution of the utility model is: motor shaft is bearing on the oiliness bearing, oiliness bearing places in the bearing chamber of electric motor end cap, wherein bearing gland has been withheld in the outside of electric motor end cap, and bearing gland is fixedlyed connected with electric motor end cap, be provided with the bearing shell fragment in the cavity that electric motor end cap and bearing gland surround, the elastic claw of bearing shell fragment is pressed on the oiliness bearing, and the bearing shell fragment is fixed on the bearing gland.
Also be filled with the grease fiber in the cavity that above-mentioned electric motor end cap and bearing gland surround.
The bearing chamber of above-mentioned electric motor end cap is made and is that v-shaped structure, oiliness bearing are spherical oiliness bearing, and spherical oiliness bearing is that line contacts with the V-arrangement bearing chamber.
Be arranged with axle sleeve and packing ring between the cage rotor of suit and the spherical oiliness bearing on the above-mentioned motor shaft.
Above-mentioned packing ring includes buffer gasket.
Above-mentioned packing ring also includes the wear washer that contacts with oiliness bearing.
Also be set with adjusting washer (disk) between above-mentioned buffer gasket and the wear washer.
The utility model has solved high temperature-resistant grease fibre weight problem very little in the bearing gland owing to adopt bearing gland to place the structure in the electric motor end cap outside, has prolonged the useful life of oiliness bearing.In addition, bearing chamber of the present utility model is a v-shaped structure, and spherical oiliness bearing places the V-arrangement bearing chamber, and spherical oiliness bearing is that line contacts with bearing chamber, has solved the vibrations of the bad generation of common oiliness bearing structure concentricity and the problem of noise; In addition, the grease fiber of filling in the bearing gland, rub between spherical oiliness bearing and the axle during motor rotation and make the oil resistant shuttling movement, the oil that forward direction flows can be gone back by the absorption of grease fiber, the moving oil of backward current can be stopped back by wear washer, has solved the situation of common oiliness bearing axis of no-feathering to leakage of oil.The utility model is that a kind of design is ingenious, function admirable, the supporting structure of convenient and practical motor shaft.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment:
Structural representation of the present utility model as shown in Figure 1, motor shaft 10 is bearing on the oiliness bearing 4, oiliness bearing 4 places in the bearing chamber 1A of electric motor end cap 1, wherein bearing gland 2 has been withheld in the outside of electric motor end cap 1, and bearing gland 2 is fixedlyed connected with electric motor end cap 1, be provided with bearing shell fragment 3 in the cavity that electric motor end cap 1 and bearing gland 2 surround, the elastic claw 31 of bearing shell fragment 3 is pressed on the oiliness bearing 4, and bearing shell fragment 3 is fixed on the bearing gland 2.
Also be filled with grease fiber 9 in the cavity that above-mentioned electric motor end cap 1 and bearing gland 2 surround.
In the present embodiment, the bearing chamber 1A of above-mentioned electric motor end cap 1 makes and is v-shaped structure, and oiliness bearing 4 is spherical oiliness bearing, and spherical oiliness bearing is that line contacts with the V-arrangement bearing chamber.
In addition, be arranged with axle sleeve 8 and packing ring between the cage rotor 11 of suit and the spherical oiliness bearing 4 on the above-mentioned motor shaft 10.In the present embodiment, above-mentioned packing ring includes buffer gasket 7.Above-mentioned packing ring also includes the wear washer 5 that contacts with oiliness bearing 4.Also be set with adjusting washer (disk) 6 between above-mentioned buffer gasket 7 and the wear washer 5.
Operation principle of the present utility model is as follows: during the motor rotation, friction makes the oil resistant shuttling movement between spherical oiliness bearing 4 and the axle, the oil that forward direction flows can be adsorbed go back (it is forward direction that custom claims motor shaft to stretch out direction) by grease fiber 9, the moving oil of backward current can be stopped back by wear washer 5, has solved the situation of common oiliness bearing axis of no-feathering to leakage of oil.
