Abstract
The utility model relates to the technical field of electric machine, especially indicate a pretightning force adjusting device for motor, including the motor main part, the motor main part includes shell, coil, bearing, pivot, front end housing and rear end cap, the rear end cap inboard is equipped with the cylindricality chamber, the cylindricality intracavity is located to the bearing, the cylindricality intracavity still is equipped with wave spring piece and pressure adjusting pad, be equipped with a plurality of screws on the rear end cap, the screw passes the rear end cap and is connected to on the pressure adjustment gasket. The utility model discloses an above -mentioned technical scheme's beneficial effect as follows: simple structure, the technique is reasonable, and low cost adjusts the pressure of wave spring piece through adjusting screw, need not disassemble the motor moreover, and it is very convenient to operate to shi yeke in the motor operation carries out interim adjustment, makes the motor all can be in optimum running state always, thereby has guaranteed the life of motor.
Description
Technical field
The utility model relates to technical field of motors, refers to a kind of pre-tightening force adjusting device for motor especially.
Background technology
Total institute is known, and wavy spring sheet is one of parts of motor, and it has a certain impact to motor oscillating and noise, larger on the impact of axial movement of motor.Because bearing also exists end-play, when motor runs, rotor can be subject to an axial electromagnetic force, therefore axial vibration and noise can be produced in motor runs, solution applies certain axial precompression to motor bearings, and in order to regulate the end-play of bearing, the axial electromagnetic force born about rotor provides a resistance, thus the vibration & noise of motor is inhibited, therefore the precompression selection of wavy spring is improper, and effect is just bad, and even noise strengthens on the contrary.When precompression is too small, still there is larger end-play in bearing, also cannot the balance motor rotor axial force of bearing, and axial transmission still exists, and the buzz that the low frequency of reflection axial endplay, cycle occur also can not reduce.When precompression is excessive, the end-play of bearing diminishes and even disappears, and affect the normal use of bearing, make bearing operation dumb, motor sends high frequency shriek, causes noise of motor very large, even makes the lost of life of bearing.
To sum up state, in prior art, there are two shortcomings:
1, the pressure of wavy spring sheet is determined by decrement, and this decrement is then determined by the cumulative limit of parts multiple in motor, so accordingly, this decrement cannot strict guarantee.And under the prior art, wavy spring sheet is all, after putting into motor, forever cannot adjust pressure, as needed adjustment, then need motor to disassemble.
2, along with the operation of motor, the play in bearing can strengthen, and the pressure that wavy spring sheet produces then can reduce, and corresponding precompression then can be not enough, thus affect the effect of motor operation, shortens electrical machinery life.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of pre-tightening force adjusting device for motor, along with motor runs, can carry out interim adjustment, make motor be in optimized operation state always.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of pre-tightening force adjusting device for motor, comprise motor body, described motor body comprises shell, coil, bearing, rotating shaft, front end housing and rear end cap, be provided with bearing chamber inside described rear end cap, described bearing is located in bearing chamber, is also provided with wavy spring sheet and pressure adjustment cushion block in described bearing chamber, described rear end cap is provided with some screws, and described screw is connected to pressure through rear end cap and regulates on pad.
As preferably, described pressure regulates cushion block, wavy spring sheet and bearing to be circulus, described pressure regulate cushion block, wavy spring sheet and bearing suitable be socketed in rotating shaft one end.
The beneficial effect of technique scheme of the present utility model is as follows: structure is simple, technology is reasonable, with low cost, regulated by the pressure of adjustment screw to wavy spring sheet, and do not need to disassemble motor, operation is very easy, and also can carry out interim adjustment when motor runs, make motor all can be in optimized operation state always, thus ensure that the useful life of motor.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of pre-tightening force adjusting device embodiment for motor of the present utility model.
In figure 1, pressure regulates cushion block, and 2, screw, 3, wavy spring sheet, 4, rear end cap.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of pre-tightening force adjusting device for motor for existing deficiency, as shown in Figure 1, comprise motor body, described motor body comprises shell, coil, bearing, rotating shaft, front end housing and rear end cap 4, be provided with cylinder chamber inside described rear end cap 4, described bearing is located in cylinder chamber, is also provided with wavy spring sheet 3 and pressure adjustment cushion block 1 in described cylinder chamber, described rear end cap 4 is provided with some screws 2, and described screw 2 is connected to pressure through rear end cap 4 and regulates on pad 1.Described pressure regulates cushion block 1, wavy spring sheet 3 and bearing to be circulus, and what described pressure adjustment cushion block 1, wavy spring sheet 3 and bearing were suitable is socketed in rotating shaft one end.
When motor is assembled, cushion block 1 is regulated by pressure to load between back end cover for motor 4 and wavy spring sheet 3; After having assembled, screw 1 that rear end cap 4 is screwed on, keeps relaxed state, when motor runs, by adjustment screw 2 position, and reads empty load of motor current value, noise level, vibration values, thus reaches optimum state.
After motor is filled to terminal equipment, according to ruuning situation, adjustment screw 2 screw-in depth in good time, thus adjustment wavy spring sheet 3 decrement, make motor all can be in optimized operation state always, thus ensure that the useful life of motor.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
