Description
Technical field
This utility model is related to technical field of motor manufacture, the adjustable motor bearings component of particularly a kind of precompression.
Background technology
For many years, motor manufacturing factory fills in the ball bearing room of armature spindle and has resilient wave washer with a kind of,
Achieve the effect for reducing noise and vibration.When motor ball bearing is assembled, wavy spring packing ring is made bearing by the compression of part
Outer shroud stress, by ball, presses to bearing inner ring with diagonal, makes the rolling of ball closer to perfect condition, while
Suppress or reduce the axial float of motor using its elastic restoring force, so as to reduce vibration and the noise of motor.
Using traditional ball bearing assembling structure, after the completion of motor assembling, due to the product of rotor axial direction dimension chain
Tired error, the decrement of wavy spring packing ring is changeable, i.e. the precompression of ball bearing is uncontrollable.If pressure is too small,
During motor operation, the electromagnetic force of stator and rotor automatic aligning makes rotor axially have slight play, produces the buzz of low frequency, if
Pressure is excessive, and the ball of bearing is easily produced between inside and outside rolling element and clashes into and encourage electric machine casing vibration and produce noise,
Meanwhile, pressure crosses the work oil clearance that conference decreases or even eliminates bearing, so as to reduce the service life of ball bearing.
Content of the invention
For the deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of structure letter
Single, vibration and the noise of motor can be reduced, and the motor bearings component of motor bearings service life can be improved.
For achieving the above object, technical solution adopted in the utility model is a kind of adjustable motor shaft of precompression of design
Bearing assembly：Including armature spindle 1, end cap 5, ball bearing 8 and wavy spring packing ring 7；
A, also include adjustment block 2 that external screw thread 4 is machined with external cylindrical surface；
Bearing chamber on B, the end cap 5 is designed as through hole 6, and the left part in the through hole 6 is machined with and is coordinated with external screw thread 4
Female thread；
C, the ball bearing 8, wavy spring packing ring 7 and adjustment block 2 are sequentially arranged at the rotor in through hole 6 from inside to outside
On axle 1.
The axial via hole 3 of more than two is provided with the adjustment block 2.
The adjustable motor bearings component of precompression of the present utility model, is that the bearing chamber on end cap is designed as through hole, profit
The positioning to ball bearing and precompression adjustment is realized with the step of armature spindle, wavy spring packing ring and adjustment block, thus, its
Structure is relatively simple.Motor assembling after the completion of, by rotate adjustment block, can real-time regulation motor ball bearing precompressed
Power, makes the ball of bearing run in rational work oil clearance, and then reduces vibration and the noise of motor, and improve motor bearings
Service life.
Description of the drawings
Fig. 1 is main cross-sectional schematic diagram of the present utility model.
In figure：1 is armature spindle, and 2 is adjustment block, and 3 is axial via hole, and 4 is external screw thread, and 5 is end cap, and 6 is through hole, and 7 are
Wavy spring packing ring, 8 is ball bearing, and 9 is rotor, and 10 is stator, and 11 is stator seat, and 12 is another end cap.
Specific embodiment
Below in conjunction with drawings and Examples, this utility model is further described.Description below is using enumerating
Mode, but protection domain of the present utility model should not be limited to this.
The adjustable motor bearings component of the precompression of the present embodiment, is by armature spindle 1, end cap 5, ball bearing 8, waveform bullet
Spring packing ring 7 and adjustment block 2 are constituted.
Bearing chamber on end cap 5 is designed as through hole 6, and the through hole 6 left part (i.e.：One not connected with stator seat 11
Side) it is machined with female thread.
Adjustment block 2 is the cylinder with axis hole, is machined with external screw thread 4 on its external cylindrical surface, the external screw thread 4 and through hole 6
The screw-internal thread fit of left part；On the end face of adjustment block 2, the axial via hole of more than two (this example is designed as two) is also provided with
3 (can be through hole, alternatively blind hole, this example are designed as through hole).
During installation, the armature spindle 1 with rotor 9 is installed on the centre of the stator 10 of stator seat 11, and another end cap 12 is installed
In the right-hand member of stator seat 11, the right-hand member of the axis hole rotor bushing axle 1 of another end cap 12 (including another ball bearing).
Left end of the end cap 5 installed in stator seat 11, ball bearing 8 are sleeved on 1 left part of armature spindle in the through hole 6 of end cap 5
Step at (step props up the inner ring of ball bearing 8), and wavy spring packing ring 7 and adjustment block 2 are sleeved on rotor successively
1 left part of axle, allows the right side of wavy spring packing ring 7 to prop up the outer ring of ball bearing 8, adjustment block 2 (its external screw thread 4 and 6 left part of through hole
Screw-internal thread fit) the right side then prop up the left side of wavy spring packing ring 7, form the positioning to ball bearing 8.
During use, by axial via hole 3, adjustment block 2 is rotated so as to precession or back-out, and then change adjustment block 2
With the gap length between ball bearing 8, the decrement of wavy spring packing ring 7 changes with the size in gap, and then changes rolling
The precompression of pearl bearing 8, makes the ball of ball bearing 8 run in rational work oil clearance.
Preferred embodiments of the present utility model are the foregoing is only, this utility model is not limited to, for this
For the technical staff in field, this utility model can have various modifications and variations.All of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements that is done etc. are should be included within protection domain of the present utility model.
The adjustable motor bearings component of precompression of the present utility model, is suitable for all kinds of motors using ball bearing.
