Abstract
The utility model discloses a bearing fixing structure of a booster pump motor. The bearing fixing structure comprises a bearing, an end cover and a bush, wherein the end cover is provided with a bearing base, the lower part of the bush is provided with a bush limiting platform, the lower part of the bearing base is provided with a bearing base limiting platform, the bush is fixed in the bearing base, and the bearing is fixed in the bush. According to the bearing fixing structure of the booster pump motor, the vibration produced by operation of the motor is not directly transmitted to the end cover but counteracted through the bush, the noise is reduced, the bearing base can be formed by lathing the end cover roughly, the structure is simple and the cost is reduced.
Description
Technical field
The utility model relates to a kind of bearing fixing structure, particularly relates to a kind of booster motor bearing fixing structure.
Background technology
Traditional booster motor bearing fixed form is at the end cap bearing pedestal of getting on the bus out, then bearing is pressed in bearing pedestal.Which requires Vehicle Processing to have very high precision, the normal operation of guarantee bearing like this.In addition, end cap can be directly passed in the vibration in machine operation process, causes the generation of noise.
At present, the improvement rear bearing fixed form on market adopts mounting O-shaped rubber ring in bearing outer rim or bearing pedestal, for preventing the friction between bearing and bearing pedestal, reduces noise.But exist be easy to wearing and tearing, useful life low shortcoming.
Notification number is CN202188022U, the applying date is that the Chinese patent of 2011.07.28 discloses a kind of bearing fixing structure and had the motor of this bearing fixing structure, comprise the compensation arrangement that is provided with cavity, bearing is fixed in described cavity, described compensation arrangement and bearing pedestal are fixed by position-limit mechanism, reduce noise, improve bearing useful life.But, this bearing fixing structure relative complex, manufacturing cost is higher.
Summary of the invention
For solving the deficiency existing in prior art, technical problem to be solved in the utility model is to provide a kind of booster motor bearing fixing structure that can reduce noise.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of booster motor bearing fixing structure, comprises bearing and end cap, and described end cap has bearing pedestal, also comprise lining, described lining bottom is provided with lining limiting stand, and described bearing pedestal bottom is provided with bearing pedestal limiting stand, described lining is fixed in bearing pedestal, and described bearing is fixed in lining.
Preferably, the sectional tool of described bearing pedestal has about " L " type left part of center line symmetry and corresponding right part thereof, and the sectional tool of described lining has about " L " type left part of center line symmetry and corresponding right part thereof.
Preferably, described bearing pedestal and end cap one each other, described lining adopts soft materials.
The beneficial effect of technical solutions of the utility model is:
1, a kind of booster motor bearing fixing structure of the present utility model, owing to comprising bearing and end cap, described end cap has bearing pedestal, also comprises lining, described lining bottom is provided with lining limiting stand, described bearing pedestal bottom is provided with bearing pedestal limiting stand, and described lining is fixed in bearing pedestal, and described bearing is fixed in lining, like this, the vibration of motor rotation is not directly conducted to end cap, but offsets by lining, has lowered noise.
2, a kind of booster motor bearing fixing structure of the present utility model, because the sectional tool of described bearing pedestal has " L " type left part and the corresponding right part thereof about center line symmetry, the sectional tool of described lining has about " L " type left part of center line symmetry and corresponding right part thereof, like this, the fixed installation of bearing and lining, lining and bearing pedestal is more firm.
3, a kind of booster motor bearing fixing structure of the present utility model, due to described bearing pedestal and end cap one each other, described lining adopts soft materials.Like this, bearing pedestal can form by end cap is rough turn, simple in structure, reduces costs; Adopt soft materials, noise-decreasing better effects if; And the fixed installation of bearing and lining, lining and bearing pedestal is more convenient, more firm.
Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of a kind of booster motor bearing fixing structure of the present utility model.
Fig. 2 is the broken section structural representation of a kind of booster motor bearing fixing structure of the present utility model.
Embodiment
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
As depicted in figs. 1 and 2, a kind of booster motor bearing fixing structure of the present embodiment, comprises bearing 1 and end cap 2, and described end cap 2 has bearing pedestal 3, and described bearing pedestal 3 forms by end cap 2 is rough turn, is a part for end cap 2.
A kind of booster motor bearing fixing structure of the present embodiment also has lining 4, and the material of described lining 4 is soft metal, rubber, nylon or nonmetal polymer, can bear vibration, rub resistance.
As shown in Figure 2, the bottom of described bearing pedestal 3 has bearing pedestal limiting stand 31, the cross section of analysing and observe from it, and bearing pedestal 3 has about the left part of center line symmetry and right part, and this left part is " L " type;
Equally, the bottom of described lining 4 has lining limiting stand 41, the cross section of analysing and observe from it, and lining 4 also has about the left part of center line symmetry and right part, and this left part is " L " type.
Described lining 4 presses downward to bearing pedestal 3, until the bearing pedestal limiting stand 31 of bearing pedestal 3 props up the lining limiting stand 41 of lining 4, now, lining 4 outer walls mutually push both are fixedly connected with bearing pedestal 3 inwalls.
Described bearing 1 presses downward in lining 4, until bearing 1 is propped up by the lining limiting stand 41 of lining 4, now, bearing 1 outer wall mutually pushes both are fixedly connected with lining 4 inwalls.
When booster pump is normally worked, the motor shaft 51 of booster motor 5 is through bearing 1, and the vibration that motor 5 turns round is not directly conducted to end cap 2, but offsets through lining 4, has lowered noise.
Above specific embodiment of the utility model is described.It will be appreciated that, the utility model is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present utility model.
