Description
Technical field
The present invention relates to a kind of unilateral bearing, relate in particular to a kind of clutch coupling of washing machine unilateral bearing.
Background technique
As seen from Figure 1: combination bearing is made up of the needle roller limit of a steel ball limit of playing the carrying effect and a braking action, steel ball 4 is dispersed in the raceway of first outer ring 1 and inner ring 2 by spherical retainer 5, needle roller 6 and spring sheet 9 are evenly distributed on the periphery of the serrate slot of second outer ring 3 and inner ring 2 by cages for needle 7, first Sealing 68 and second Sealing 69 are sealed in bearing inside with lubricant grease, seal 8 is pressed in the dustproof groove of second outer ring 3 fixing and cooperates with the dustproof groove of outer ring 2 and to seal, and prevents the infiltration of bearing leakage fat and extraneous steam.But this structure since during bearing working first outer ring 1 and second outer ring 3 can relatively rotate and make and can cause that washing machine steam infiltrates by seal 8 wear out failures.Simultaneously,, make the bearing support housing difficulty of processing that cooperates with it increase, not only expended material, and increased the overall cost of clutch because bearing width is longer.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of light unidirectional bearing for washing machine clutch, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: the outer ring of one, inner ring, retainer lid, conjuncted retainer, steel ball, first Sealing and second Sealing; Described steel ball is placed in the ball pocket of conjuncted retainer; Shift to install some special-shaped pockets at the conjuncted retainer the other end and ball pocket, one side of special-shaped pocket adopts a cambered surface and positioning boss to be connected to the retainer end face, the another side of special-shaped pocket is provided with the stage body of a placement spring sheet, the boss be connected to the retainer external diameter and the boss that is connected to the retainer internal diameter are set on the stage body, are connected to the boss of retainer external diameter and are connected to the space that forms between the boss of retainer internal diameter and be used for fixing the placement spring sheet with the plane of stage body; Have several on the retainer end face in addition, be used for becoming interference fit that special-shaped son is constrained in pin-and-hole in the special-shaped pocket with bearing pin that retainer covers; Two circular arc working surfaces of described special-shaped son form a long diagonal angle cambered surface and short diagonal angle cambered surface by side-play amount, and special-shaped sub-bottom surface platform is provided with a recessed plane by step; The another side of special-shaped son is provided with a cydariform projection and a positioning groove.
Compared with prior art, the invention has the beneficial effects as follows: make that the unilateral bearing wall is thin, compact structure; Rotation Noise is low, and braking ability is good; Owing to reduced the axial length of clutch shaft bearing, the manufacture cost of having saved clutch greatly.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
By Fig. 2 A, Fig. 2 B, Fig. 3 A, Fig. 3 B, Fig. 4, Fig. 5 as seen: the present invention includes: the outer ring 10 of one and inner ring 20, retainer lid 40, conjuncted retainer 30, steel ball 70, first Sealing 80 and second Sealing 90; Described steel ball 70 is placed in the ball pocket 310 of conjuncted retainer; Shift to install some special-shaped pockets 309 at conjuncted retainer 30 the other ends and ball pocket 310, one side of special-shaped pocket adopts a cambered surface 306 and positioning boss 307 to be connected to retainer end face 301, the another side of special-shaped pocket is provided with the stage body 308 of a placement spring sheet 50, boss 303 that is connected to the retainer external diameter and the boss 304 that is connected to the retainer internal diameter are set on the stage body, and the space 305 that forms between outer lug boss 303 and the inner convex platform 304 is used for fixing placement spring sheet 50 with the plane of stage body 308; Have several on the retainer end face 301 in addition, be used for becoming interference fit with special-shaped son 60 pin-and-holes 302 that constrain in the special-shaped pocket with the bearing pin that retainer covers;
Described special-shaped 60 two circular arc working surfaces of son (601,602) form a long diagonal angle cambered surface bb ' and short diagonal angle cambered surface cc ' by side-play amount a, and special-shaped sub-bottom surface platform 607 is provided with a recessed plane 604 by step 603; Its objective is that the arc round angle 503 avoided on the spring sheet and 604 planes offset causes special-shaped sub stressed position not to causing braking failure; The another side of special-shaped son is provided with cydariform projection 606 and positioning groove 605;
Described spring sheet 50 is S shape spring sheets; One end of S shape spring sheet forms elastic angle α by inclined-plane 504 and plane 501.
When the present invention installs, special-shaped son is installed in the special-shaped pocket of retainer, special-shaped sub-cydariform boss forms with the arc surface 306 of retainer and cooperates; Convex body 307 on the retainer forms with the positioning groove 605 of special-shaped son and cooperates, and purpose is to make special-shaped son be easy to rotate around it; Spring one end is installed in the space 305 of retainer, and the inclined-plane 504 of the other end gently contacts with the plane 607 of special-shaped son.
During work, inner ring rotates toward the clockwise direction, and the arc surface 602 and 601 of special-shaped son is rotated counterclockwise an angle at the convex body 307 on keeping under the frictional force action of inner ring periphery and outer ring inner headed face respectively and forms short diagonal angle arc cc ' and make spring sheet be subjected to force compresses; At this moment, special-shaped son is being subjected to four descending one-tenth transient equiliblium of active force, and bearing is realized rotating.When inner ring when counterclockwise rotating, turn clockwise under the effect of special-shaped son circle frictional force in inner ring cylindrical and outer ring, at this moment, special-shaped son and retainer and spring sheet break away from that to form long diagonal angle arc bb ' stuck with inner ring and outer ring, bearing realization braking state.
This bearing adopts the outer ring of one and uses the structure of dual face seals, can effectively avoid the infiltration of steam to cause bearing failure.And the Internal and external cycle wall of bearing is thin, and compact structure is in light weight, and the braking angle is little, has particularly shortened the axial width of bearing, has saved the manufacturing material greatly.
