Abstract
A thorn-shaped clamp spring connection type clutch release bearing relates to auto parts, in particular to a clutch release bearing connected through a thorn-shaped clamp spring. The clutch release bearing comprises an outer ring (1), a roller (2), an inner ring (3), a bearing support (4) and the thorn-shaped clamp spring (5); an outward flanging (6) is arranged at the lower end of the thorn-shaped clamp spring (5); downward thorn bodies (7) are uniformly distributed on the outer wall; an annular clamping groove (8) is formed at the inner edge of the lower end port of the bearing support (4); the inner ring (3) is sleeved on the outer side of the lower end port of the bearing support (4); the thorn-shaped clamp spring (5) is fixed on the inner side of the lower end port of the bearing support (4) through the thorn bodies (7); and an annular pressure spring (9) is arranged between the lower end surface of the inner ring (3) and the outward flanging (6) of the thorn-shaped clamp spring (5). The utility model has the advantages of reliable connection, low probability of being scattered, and good processing technique and assembly manufacturability; besides, compared with other conventional connection methods, the production efficiency is improved by about 40 percent; and the labor intensity is greatly reduced at the same time.
Description
Technical field
The utility model relates to auto parts machinery, is specifically related to a kind of clutch release bearing that adopts spine clamp-spring to connect.
Background technique
Generally speaking, clutch release bearing is made of bearing support, angular contact ball bearing, Sealing, resilient coupling etc., is the important component part of clutch release system.Clutch release system is a kind of mechanical device that cuts off power transmission between motor car engine and driver circuit.All use mechanical coupling or hydraulic pressure installation traditionally, exert pressure to clutch release bearing by clutch separation controlling rod (shift fork), clutch release bearing promotes or the pull-up clutch diaphragm spring again, motor is separated from the power conveying circuit, thereby realize purposes such as vehicle starting, stagnation of movement and gear shift.
Exist being connected between its bearing of existing clutch release bearing and bearing support or connect reliably inadequately, or processing technology and assembly process process are not ideal enough, and manufacturing efficiency is low, and has increased the shortcoming of labor intensity.
The model utility content
Technical problem to be solved in the utility model is: a kind of reliable, processing technology and good spine clamp-spring connected clutch release bearing of assembly process process of connecting is provided.
Technical solution of the present utility model is: it comprises outer ring, roller, inner ring, bearing support and spine clamp-spring, spine clamp-spring is the cirque body that the lower end is provided with flanging, the outer wall of spine clamp-spring be evenly equipped with towards under the quil body, the inner edge place of bearing support lower end mouth is provided with the annular slot that cooperates with the quil body, inner ring is enclosed within the bearing support lower end mouth outside, spine clamp-spring is fixed on bearing support lower end mouth inboard by the quil body, be provided with annular stage clip between the flanging of inner ring lower end surface and spine clamp-spring, the inner ring lower end surface is spacing by the flanging of stage clip and spine clamp-spring.
Technique effect of the present utility model is: it have connect reliable, be difficult for the sequence of sanqu songs within a particular musical mode and processing technology and the good advantage of assembly process process, manufacturing efficiency improves about 40% than other connecting mode commonly used, labor intensity also has largely and reduces simultaneously.
Description of drawings
Fig. 1 is a sectional structure chart of the present utility model;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is the A place partial enlarged view of Fig. 1.
Embodiment
As Fig. 1, shown in 2 and 3, the spine clamp-spring connected clutch release bearing of present embodiment, comprise outer ring 1, roller 2, inner ring 3, bearing support 4 and spine clamp-spring 5, spine clamp-spring 5 is provided with the cirque body of flanging 6 for the lower end, the outer wall of spine clamp-spring 5 be evenly equipped with towards under quil body 7, the inner edge place of bearing support 4 lower end mouth is provided with the annular slot 8 that cooperates with quil body 7, inner ring 3 is enclosed within the bearing support 4 lower end mouth outside, spine clamp-spring 5 is fixed on bearing support 4 lower end mouth inboards by quil body 7,6 of the flangings of inner ring 3 lower end surfaces and spine clamp-spring 5 are provided with annular stage clip 9, and inner ring 3 lower end surfaces are spacing by the flanging 6 of stage clip 9 and spine clamp-spring 5.
Be provided with retainer 10 between described outer ring 1 and the inner ring 3, roller 2 by retainer 10 at interval.
Be provided with 11,12 sealings of front and back ends seal ring between described outer ring 1 and the inner ring 3.
The utility model structure has the self-regulated heart function, wherein, the effect of stage clip 9 is that the angular contact ball bearing that will be made of outer ring 1, roller 2 and inner ring 3 etc. is clamped on the bearing support 4, when the rotating center of the misalignment clutch diaphragm spring of angular contact ball bearing, the contact force of diaphragm spring and bearing outer ring 1 (moving-coil) will produce differential slip, bearing centre is moved, until overlapping with the rotating center of diaphragm spring along the rotating center of spiral trajectory to diaphragm spring.Above-mentioned aligning process generally will be through several times clutch operation.In case aligning finishes, angular contact ball bearing just remains on concentric position by stage clip 9.Another effect of stage clip 9 is to prevent inner ring 3 (Jing Quan) rotation.The effect of spine clamp-spring 5 then is as coupling angular contact ball bearing and bearing support 4 to be linked together in this structure.Be filled with high temperature grease between the angular contact ball bearing front and back ends seal ring 11,12 to guarantee the sufficient lubrication in the life time.The thermoplastic material that bearing support 4 uses glass fibre to strengthen is made, and its endoporus that slides on conduit need not add lubricating grease.The effect of retainer 10 then is that rolling element is equally spaced, is distributed on the circumference of raceway to run foul of each other and to rub and to guide, to drive rolling element between rolling element when preventing work and roll on correct raceway.
Spine clamp-spring 5 its materials are made for the Steel Spring Plate punching press, require to quench temper.
The sour jujube shape of the spine clamp-spring 5 quil body 7 that turns up snaps in the bearing support annular slot 8, and its flanging 6 is pushed down stage clip 9 simultaneously, at this moment, will guarantee that whole angular contact ball bearing is close to bearing support 4 with suitable confining force, thereby reaches the whole purpose that effectively connects.
After this structure was in place, the sour jujube shape of the spine clamp-spring 5 quil body 7 that turns up withstood bearing support 4 concave station faces through stage clip 9 tensioners, and the sequence of sanqu songs within a particular musical mode risk of having evaded angular contact ball bearing has effectively strengthened reliability of structure.
This structure can adopt normal trap, again stage clip 9 is set on the spine clamp-spring 5, directly use hydraulic press that spine clamp-spring 5 is depressed in bearing support 4 annular slots 8, assembly process process is good, manufacturing efficiency improves about 40% than other connecting mode commonly used, and labor intensity also has reduction largely simultaneously.
