Abstract

The utility model provides a special axial plane oil blanket of motor which characterized in that: it comprises metal casing and rubber circle, the metal casing is the ring form, is equipped with the recess that circumference was arranged in the ring periphery, and the ring internal diameter cooperates with the motor shaft, rubber circle inner circle is location portion, and is fixed with the recess cooperation on the metal casing, and the periphery is the sealing, is to the crooked structure in motor installation end cover one side. The utility model has simple structure, low cost and good dustproof performance, can reach IP65 of international protection level standard, and meets the requirements of European and American imports; meanwhile, the quality and the service life of the motor are greatly improved; the noise of the motor can be reduced, and the environment-friendly effect is achieved.

Description

The special-purpose axial plane oil sealing of motor
Technical field
The utility model relates to a kind of parts of motor, is specifically related to a kind of axial plane oil sealing that is used to seal gap between motor shaft and end cap.
Background technology
One end of motor is provided with end cap, and motor shaft passes through the hole of end cap central authorities, and has the gap between end cap, and motor shaft is freely rotated in the hole.Yet owing to there is the gap, the solid foreign materials ability that prevents in its international degree of protection can only reach 3 grades, and the dust even the little grains of sand can enter in the motor, are adsorbed in the lubricating oil of bearing, causes motor performance to descend, and noise increases.
When motor exports, in order to improve the degree of protection of motor, make it meet the import requirement of the European Union and the U.S., usually in the electric motor end cap inboard, the bearing front end adds outside framework oil seal, outside framework oil seal is fixed in the electric motor end cap inboard usually, and seal by seal between motor shaft, and by tightness, motor shaft and seal intercropping relative motion between elastic component control seal and motor shaft.This structure, can obtain well dustproof, waterproof effect, still, on the one hand, the structure relative complex of outside framework oil seal, motor cost is improved, on the other hand, when mounted, because motor shaft and seal are done relative motion, to the requirement on machining accuracy height of motor shaft, motor shaft must further increase cost through one grinding technology.Therefore, present domestic motor, most of mode with the reduction degree of protection reduces cost, and is affected the useful life of domestic electric machine.
Summary of the invention
The utility model purpose provides and a kind ofly can realize the special-purpose axial plane oil sealing of the motor that seals between motor shaft and end cap with simple structure, increases the degree of protection that effectively improves motor with lower cost.
For achieving the above object, the technical solution adopted in the utility model is: the special-purpose axial plane oil sealing of a kind of motor, form by metal-back and rubber ring, described metal-back is circular, and the annulus periphery is provided with the groove of circumferential arrangement, and internal radius cooperates with motor shaft, described rubber ring inner ring is the location division, fix with the groove fit on the metal-back, periphery is a sealing, is the structure that end cap one lateral bending song is installed to motor.
Further technical scheme, the lateral border of described metal-back groove is bending extension to the inside, constitutes rubber ring protection structure.
During use, axial plane oil-sealing sleeve of the present utility model is located on the motor shaft, makes the sealing of rubber ring be close to electric motor end cap, when motor rotates, the axial plane oil sealing rotates with motor shaft, and slide relative between the sealing of rubber ring and electric motor end cap constitutes the protection to the gap of electric motor end cap and motor shaft.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. the utility model simple structure of adopting metal-back to cooperate with rubber ring has realized the clearance seal between electric motor end cap and motor shaft, and anti-dust performance is good, can reach the IP65 of international degree of protection standard, meets the requirement of American-European import;
2. the utility model good seal performance protects bearing grease moist more than 3 years, has improved motor quality and useful life greatly;
3. the utility model is simple in structure, and cost is low, is suitable for using on all kinds of motors;
4. after using the utility model product, can also reduce motor noise, reach the effect of environmental protection.
Description of drawings
Accompanying drawing 1 is the structural representation (partly cuing open) of the utility model embodiment one;
Accompanying drawing 2 is the right view of Fig. 1;
Accompanying drawing 3 is installed on the partial schematic sectional view at electric motor end cap place for the product of embodiment one.
Wherein: [1], metal-back; [2], rubber ring; [3], groove; [4], location division; [5], sealing; [6], axle; [7], end cap; [8], gap.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to accompanying drawing 1 to shown in the accompanying drawing 3; the special-purpose axial plane oil sealing of a kind of motor; it is made up of metal-back 1 and rubber ring 2; described metal-back 1 is circular; the annulus periphery is provided with the groove 3 of circumferential arrangement; internal radius cooperates with motor shaft 6; described rubber ring 2 inner rings are location division 4; cooperate fixing with the groove 3 on the metal-back 1; periphery is a sealing 5; be the structure that end cap one lateral bending song is installed to motor, the lateral border of metal-back groove 3 is bending extension to the inside, constitutes rubber ring protection structure.
During installation, as shown in Figure 3, the present embodiment product is set on the motor shaft 6, the sealing 5 of rubber ring is close to electric motor end cap 7.Because internal radius cooperates with motor shaft 6, form a fixed connection between the two, metal-back 1 rotates with motor shaft 6, simultaneously, the sealing 5 of rubber ring slides with respect to electric motor end cap 7, and good protective action is played in the gap that sealing electric motor end cap 7 and motor shaft are 6.

Claims (2)

1. the special-purpose axial plane oil sealing of a motor, it is characterized in that: it is made up of metal-back [1] and rubber ring [2], described metal-back [1] is circular, the annulus periphery is provided with the groove [3] of circumferential arrangement, internal radius cooperates with motor shaft, and described rubber ring [2] inner ring is location division [4], cooperates fixing with groove [3] on the metal-back [1], periphery is sealing [5], is the structure that end cap one lateral bending song is installed to motor.
