Rectangular rubber ring adaptive temperature variable quantity is small, and the variable quantity that expands with heat and contract with cold is big；The bad control of axial clearance of motor, easily causes motor
It is axial stuck.Drawbacks described above affects the using effect of Related product.
Utility model content
The utility model technical problem of being solved is to provide a kind of reduction motor vibration because of caused by rotor axial play
Dynamic and noise, meets motor to the electric machine vibration reducer for requirement of expanding with heat and contract with cold.
The utility model adopts the following technical solution:
The utility model includes electric machine casing, shaft, stator and rotor, installs axle sleeve in shaft outer circle, in the axis
It covers end and recess slot is set, rubber damping circle is installed in recess slot, the section of the rubber damping circle is circle；In the rubber
Graphite pad is installed between glue damping ring and spherical oiliness bearing end.
End cap shaft hole is arranged in the middle part of electric machine casing end face in the utility model, in electric machine casing inner sidewall outside end cap shaft hole
It is in bowl-shape bearing support bowl that side setting is integrally formed with electric machine casing, is arranged on the outside of bearing support bowl and is integrally formed with it
Annular oil storage tank, the spherical shape oiliness bearing side end sleeve is in the bearing support bowl, in annular oil storage tank outboard end
Bearing tabletting is fixedly mounted, lubricating oil is set in annular oil storage tank.
The utility model good effect is as follows: the section of the utility model rubber damping circle is circle, such rubber damping
It is big to enclose the magnitude range that vibration damping elastic force changes and changes with stroke, tends to flat linear variation, adaptation range is wide, effectiveness in vibration suppression
Preferably；Section is that circular rubber damping circle has variable quantity compensation function on spatial volume, and adaptive temperature variable quantity is big, more
Adapt to the requirement that motor expands with heat and contract with cold.
Annular oil storage tank is directly set on electric machine casing, and bearing support bowl and annular oil storage tank are integrally formed and are arranged, save
Material, when installation, are time saving and energy saving, and reduce production cost；End-cap assembly is few, and the processing is simple, and work efficiency is high, is applicable in
Produce in enormous quantities in automation, improves economic benefit.

Specific embodiment
As illustrated in the accompanying drawings from 1 to 3, the utility model includes electric machine casing 1, shaft 2, stator 3 and rotor 4, in 2 outer circle of shaft
Upper installation axle sleeve 5 installs axle sleeve 5 in 4 two sides of rotor respectively, recess slot 14 is arranged in 5 end of axle sleeve, in recess slot 14
Rubber damping circle 6 is installed, the section of the rubber damping circle 6 is circle；In the rubber damping circle 6 and spherical oiliness bearing 7
Graphite pad 8 is installed between end.
As shown in Fig. 4, end cap shaft hole 9 is arranged in the utility model in the middle part of 1 end face of electric machine casing, in electric machine casing 1
It is in bowl-shape bearing support bowl 10 that side wall is arranged integrally formed with electric machine casing 1 on the outside of end cap shaft hole 9, in bearing support bowl
10 outside settings are mounted in bearing support with its integrally formed annular oil storage tank 11, the spherical shape 7 side end sleeve of oiliness bearing
In bowl 10, bearing tabletting 12 is fixedly mounted in annular 11 outboard end of oil storage tank, 12 middle through-hole of bearing tabletting is pressed in spherical shape
On 7 the other end of oiliness bearing；Lubricating oil 13 is set in annular oil storage tank 11.Lubricating oil 13 is wool malthoid or permawick
Oil.
First axle sleeve 5 is inserted in the shaft 2 of rotor 4 when processing, then rubber damping circle 6 is inserted in axle sleeve 5 from shaft 2
Recess slot 14 in, then Graphite pad 8 is inserted in rubber damping circle 6 from shaft 2 and is affixed;8 other side of Graphite pad
It is affixed with spherical 7 end face of oiliness bearing, and there are appropriate gaps.
The section of the utility model rubber damping circle 6 is circle, is symmetrically mounted on 5 end of axle sleeve of 4 two sides of rotor, in this way
6 vibration damping elastic force of rubber damping circle is big with the magnitude range that stroke changes and changes, and tends to flat linear variation, adaptation range
Width, effectiveness in vibration suppression are preferable；Section is that circular rubber damping circle 6 has variable quantity compensation function on spatial volume, adapts to temperature
Spend the requirement that variable quantity is big, and more adaptation motor expands with heat and contract with cold.
