Abstract
The utility model relates to a rolling pin slope type uni-directional bearing with a folding edge structure plate spring. The bearing comprises a bearing outer ring and a bearing inner ring, wherein a pin-shaped retaining frame and a spherical retaining frame are arranged between the bearing outer ring and the bearing inner ring; a steel ball is arranged on the axial inner side of the spherical retaining frame; and a rolling pin and the plate spring are arranged on the axial inner side of the pin-shaped retaining frame. The bearing is characterized in that: one plane of the plate spring is contacted with the pin-shaped retaining frame; the other plane of the plate spring is contacted with the rolling pin; and folding edges are respectively arranged on the end parts of the two planes, contacted with the pin-shaped retaining frame and the rolling pin, of the plate spring. The plate spring is S-shaped. The efficiency of assembling springs is improved and the production cost is reduced; the phenomenon that the rolling pin is scraped by broken burrs of the primary spring is effectively avoided, the anti-noise performance of a product is improved, and finally, the service life of the bearing is prolonged; and the phenomenon that the fixation of the broken burrs of the primary spring is not reliable can be effectively avoided, the stop performance of the product is improved, and the performance of the bearing is improved.
Description
Technical field
The utility model relates to a kind of bearing with new flat spring, and especially a kind of unidirectional axis of a cylinder of needle roller ramp type with flanging structural panel spring holds.
Background technique
Concerning present bearing manufacturing, the kind of bearing is more, and the bearing of some specific uses also uses comparatively extensive; Especially a kind of needle-type unilateral bearing; In the washing machine industry, use particularly outstandingly, the unidirectional running through bearing realizes the work of washing machine.And for the working principle of existing unilateral bearing, as shown in Figure 1, reach a stop requirement through needle roller 8, lasso inclined-plane 9, S template spring 10 threes; But in actual course of working, can often find that S template spring 10 processing incision positions (B place) can be jagged, to such an extent as to spring stress is inhomogeneous; Influence bearing stop performance; And burr scratches the needle roller surface easily, influences the noise of bearing, finally influences the function of use and the life-span of bearing.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology; Provide a kind of unidirectional axis of a cylinder of needle roller ramp type with flanging structural panel spring that can improve assembling work efficient to hold; Can be very effectively with the burr of spring incision position away from working surface; Guarantee spring, needle roller, retainer triangular stressed evenly, make bearing reach the stop performance requirement of expection; Reduce the needle roller surface simultaneously and contact the situation that is scratched, produces different sound, guarantee the stable performance of bearing because of burr with the spring incision position.
The technological scheme that provides according to the utility model; The said unidirectional axis of a cylinder of needle roller ramp type with flanging structural panel spring holds; Comprise bearing outer ring and bearing inner race; Aciculiform retainer and spherical retainer are arranged between bearing outer ring and bearing inner race, be provided with steel ball, be provided with needle roller and leaf spring in the axial inboard of aciculiform retainer in the axial inboard of spherical retainer; Characteristic is: a plane of said leaf spring contacts with the aciculiform retainer, and another plane contacts with needle roller, and said leaf spring is respectively equipped with flanging with the end on two planes that the aciculiform retainer contacts with needle roller.
Said leaf spring is S-type.
The utlity model has following advantage:
(1) because of not being bonded together between spring and spring, when mounting spring, solved the problem of installing again after former need separate spring with tweezers, thereby improved mounted elastically efficient greatly, reduced cost of production;
(2) can solve the phenomenon of the fracture burr of former spring effectively, thereby improve the noise abatement performance of product, the working life of finally improving bearing the needle roller scuffing;
(3) can solve the fixing insecure phenomenon of fracture burr of former spring effectively, thereby improve the stop performance of product, improve the performance of bearing;
(4) this spring structure is simple and reliable.

Embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
Like Fig. 2 ~ shown in Figure 5: the unidirectional axis of a cylinder of needle roller ramp type with flanging structural panel spring is contracted and is drawn together bearing outer ring 1, bearing inner race 2, aciculiform retainer 3, needle roller 4, leaf spring 5, spherical retainer 6, steel ball 7 etc.
The utility model comprises bearing outer ring 1 and bearing inner race 2; Aciculiform retainer 3 and spherical retainer 6 are arranged between bearing outer ring 1 and bearing inner race 2; Axial inboard at spherical retainer 6 is provided with steel ball 7, is provided with needle roller 4 and leaf spring 5 in the axial inboard of aciculiform retainer 3, and said leaf spring 5 is S-type; One plane of leaf spring 5 contacts with aciculiform retainer 3, and another plane contacts with needle roller 4; Said leaf spring 5 is respectively equipped with flanging with the end on two planes that aciculiform retainer 3 contacts with needle roller 4.
Bearing outer ring 1 that the described unidirectional axis of a cylinder of the utility model holds and bearing inner race 2 are fixed through steel ball 7 and spherical retainer 6 assembling backs, and needle roller 4 is pressed in the groove of bearing outer ring 1 after assembling with aciculiform retainer 3, leaf spring 5, thereby are fixed on bearing inside.The stop performance system that the unidirectional axis of a cylinder of the utility model holds is by bearing outer ring 1, bearing inner race 2, needle roller 4, aciculiform retainer 3, spherical retainer 6 and the assembling of leaf spring 5 cooperating structures.Needle roller 4 is packed into leaf spring 5 behind the aciculiform retainer 3, through leaf spring 5 elastic force, the three is fixed into an assembly; This moment, leaf spring 5 one planes contacted the location with aciculiform retainer 3, and another plane then contacts with needle roller 4, through the improvement to leaf spring 5 structures; Change the situation that contacts of leaf spring 5 and aciculiform retainer 3 and needle roller 4; Can improve the location of leaf spring 5 effectively, also can reduce the problem that needle roller 4 is scratched effectively, reach one and do not influence the effect of product noise and stop performance because of there is the fracture burr in leaf spring 5; Thereby improve the usability of product, the working life that can improve bearing.
