Abstract
The utility model discloses a unidirectional needle bearing with a single-foot leaf spring. The unidirectional needle bearing comprises a stamped outer ring made from sheet steel, a nylon retainer, a quill roller and a ferrule. The nylon retainer is arranged between an inner rolling path of the stamped outer ring and the ferrule. The quill roller is arranged in a window of the nylon retainer. The leaf spring is arranged in the nylon retainer and has a single foot. One end of the leaf spring is fixedly connected with the nylon retainer, and the other end of the leaf spring makes contact with the quill roller. The unidirectional needle bearing has the advantages that the frictional force between the quill roller and a shaft after the leaf spring abuts against the quill roller is reduced, the requirement of a customer for bearing performance is met, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of unilateral bearing of novel retainer, especially a kind of unidirectional needle bearing of single pin spring sheet.
Background technique
Lower at unilateral bearing height overall, under the restricted condition of installing space, due to the total height of bearing, needle roller length is shorter (general <6mm length) also, now, if use again conventional double-legged spring sheet, make needle roller be subject to two forces, the frictional force that needle roller is withstood between rear and axle by spring sheet so strengthens, and in operation process, according to meeting, causes heating, reduces the working life of bearing.
Model utility content
Technical problem to be solved in the utility model is: when restricted for installing space, bearing height overall is corresponding will be reduced, thereby cause needle roller length shorter, as re-use conventional double-legged spring sheet, the frictional force that needle roller is withstood between rear and axle by spring sheet strengthens, cause heating, therefore propose a kind of unidirectional needle bearing of single pin spring sheet.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of unidirectional needle bearing of single pin spring sheet, comprise the drawn cup, nylon cages, needle roller and the lasso that by sheet metal, are processed into, between the interior raceway of described drawn cup and lasso, be provided with nylon cages, in the fenestra of described nylon cages, be provided with needle roller, and be provided with spring sheet in described nylon cages, described spring sheet is single pin, one end of described spring sheet is fixedly connected with nylon cages, and the other end contacts with needle roller.
In preferred embodiment of the utility model, described spring sheet is Compress Spring or clockwork spring.
In preferred embodiment of the utility model, the length of described needle roller is 1-5mm.
The unidirectional needle bearing of single pin spring sheet of the present utility model, has reduced needle roller and has been withstood the frictional force between rear and axle by spring sheet, meets client to bearing performance needs, has improved the working life of bearing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the unidirectional needle bearing of the utility model list pin spring sheet;
Fig. 2 is a view of the retainer of this bearing;
Fig. 3 is the partial view A seeing from top to bottom from Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, drawn cup 2, nylon cages 3, needle roller 4, lasso, 5, spring sheet.
Embodiment
Below be only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with a preferred embodiment and accompanying drawing, the technical solution of the utility model is further described.
Consult Fig. 1, a kind of unidirectional needle bearing of single pin spring sheet, comprise the drawn cup 1, nylon cages 2, needle roller 3 and the lasso 4 that by sheet metal, are processed into, between the interior raceway of described drawn cup 1 and lasso 4, be provided with nylon cages 2, in the fenestra of described nylon cages 2, be provided with needle roller 3, and be provided with spring sheet 5 in described nylon cages 2, described spring sheet 5 is single pin, one end of described spring sheet 5 is fixedly connected with nylon cages 2, and the other end contacts with needle roller 3.
Further illustrate, described spring sheet is Compress Spring or clockwork spring, and the length of described needle roller is 1-5mm.
The unidirectional needle bearing of a kind of single pin spring sheet of the present utility model, comprises the punching press needle roller clutch bearing that the drawn cup, nylon cages, needle roller and the lasso that are processed into by sheet metal form.In drawn cup, between raceway and lasso, be provided with nylon cages, in the fenestra of nylon cages, be provided with needle roller, and in nylon cages, be provided with spring sheet, one end is fixedly connected with nylon cages, the other end contacts with needle roller, makes spring sheet and nylon cages form an integral body, and the feature of its nylon cages is that its spring sheet is single pin, make that needle roller is stressed is unlikely to excessive, thereby after having reduced needle roller and being withstood by spring sheet and the frictional force between axle.Advantage is: one, because the spring sheet contacting with needle roller is single pin, therefore reduce starting torque, and reduced noise; Its two, due to spring sheet and retainer as a whole, reduced the manufacturing procedure that shoots reed, eliminated the possibility of workman's neglected loading spring sheet, guaranteed the quality of bearing.Be mainly used in unilateral bearing height overall lower, under the restricted condition of installing space, due to the total height of bearing, needle roller length is shorter (general <6mm length) also, now, if use again conventional double-legged spring sheet, make needle roller be subject to two forces, the frictional force that needle roller is withstood between rear and axle by spring sheet so strengthens, and in operation process, according to meeting, causes heating, reduces the working life of bearing.The utlity model has reduced needle roller and withstood by spring sheet after and the frictional force between axle, meet client to bearing performance needs, improved the working life of bearing.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; everyly utilize equivalent structure or the equivalent flow process that the utility model specification and accompanying drawing content are done to slow down; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
