Stability is poor.
Summary of the invention
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, to provide that a kind of stability is high and structure is tight
The high temperature resistant vehicle air-conditioning bearing to gather.
The purpose of this utility model can be realized by the following technical scheme:
A kind of high temperature resistant vehicle air-conditioning bearing, including outer ring, inner ring and ball, inner ring are located on the inside of outer ring, the ball
Quantity be several, several balls are evenly arranged between outer ring and inner ring, which is characterized in that are had on the inside of the inner ring recessed
Positioning recess further includes the attachment base being in U-shape, and the U-shaped bottom of attachment base matches with positioning recess and attachment base and positioning are recessed
Tight-lipped mating connection, the U-shaped recess of the attachment base are the keyway being connected for flat key, further include a gasket flexible, on
Gasket is stated to be pressed between positioning recess and attachment base.
Due to having several balls between outer ring and inner ring, outer ring can be relative to the smooth rotation of inner ring.
It is creative in this bearing that positioning recess has been opened up on inner ring, and gasket and company are connected at positioning recess
Joint chair is avoided that attachment base and inner ring rigid contact by gasket.Make to be stably connected between inner ring, flat key and axis by attachment base
Together.
In above-mentioned high temperature resistant vehicle air-conditioning bearing, the gasket is flameproof fabric.
In above-mentioned high temperature resistant vehicle air-conditioning bearing, the gasket is mineral wool.
In above-mentioned high temperature resistant vehicle air-conditioning bearing, the U-shaped end of the attachment base has the gear protruded outward
Edge, above-mentioned gear edge are resisted against on the inside of inner ring.
By keeping off along the contact area that can increase between attachment base and axis, guarantee its connective stability.
Have in above-mentioned high temperature resistant vehicle air-conditioning bearing, at the port of the positioning recess is in step-like recessed platform
Rank seat, above-mentioned gear is along at mount.
In above-mentioned high temperature resistant vehicle air-conditioning bearing, the gear edge and flush on the inside of inner ring.
The setting of mount can be to gear along stable position, while can also improve the structural compactness of entire bearing.
In above-mentioned high temperature resistant vehicle air-conditioning bearing, the gear has the contact portion of concave-convex surface along end.
Such structure can increase the frictional resistance between contact portion and axis, improve the stable connection between inner ring and axis
Property.
That is, there are two types of usage modes for this bearing:
One, flat key two sides be connected on attachment base and axis, since attachment base is stably connected on inner ring, finally
It is stably connected with inner ring with axis；
Secondly, the frictional resistance between inner ring and axis improved by contact portion, do not need to make by flat key yet inner ring with
Axis is stably connected with.
In above-mentioned high temperature resistant vehicle air-conditioning bearing, there is recessed deformation hole on the inside of the U-shaped of the attachment base.
Contact portion in loading process, play certain buffering and make by the appropriate deformation of attachment base energy under the action of deformation hole
With.
In above-mentioned high temperature resistant vehicle air-conditioning bearing, the attachment base and gear edge are an integral structure and are polyimides
Material.
The attachment base of this material not only high temperature resistant, and intensity is high and has proper toughness.
In above-mentioned high temperature resistant vehicle air-conditioning bearing, the quantity on the gear edge is two and two gears along symmetrical distribution
In connection seat both sides, above-mentioned mount is arranged in a one-to-one correspondence with gear edge.
Structural compactness can not only be improved in this way, and also ensures the connective stability between inner ring and axis.
Compared with prior art, in this high temperature resistant vehicle air-conditioning bearing can make after the U-shaped recess of attachment base connects flat key
Circle is stably connected with axis.Or directly guaranteeing that inner ring is stably connected with axis by attachment base, usage mode is more, applicability
It is high.
Simultaneously as attachment base and axis contact area are big, therefore, connective stability is high, and structure is compact, tool
There is very high practical value.
