Abstract
The invention discloses a one-way needle bearing of a one-foot spring piece. The one-way needle bearing comprises a stamping outer ring, a nylon holder, a needle roller and a ferrule. The stamping outer ring is made of sheet steel, the nylon holder is arranged between an inner rolling way of the stamping outer ring and the ferrule, the needle roller is arranged in a window hole of the nylon holder, the one-foot spring piece is arranged in the nylon holder, and one end of the spring piece is fixedly connected with the nylon holder while the other end of the spring piece is contacted with the needle roller. The one-way needle bearing of the one-foot spring piece has the advantages that friction force between a shaft and the needle roller jacked by the spring piece, requirements of clients on bearing performances can be met, and service life of the bearing is prolonged.
Description
Technical field
The present invention 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, frictional force after needle roller is withstood by spring sheet so and between axle strengthens, and in operation process, causes heating according to meeting, reduces the working life of bearing.
Summary of the invention
Technical problem to be solved by this invention 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, frictional force after needle roller is withstood by spring sheet and between axle 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 present invention 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 are processed into by sheet metal, 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 a preferred embodiment of the present invention, described spring sheet is Compress Spring or clockwork spring.
In a preferred embodiment of the present invention, the length of described needle roller is 1-5mm.
The unidirectional needle bearing of single pin spring sheet of the present invention, has reduced the frictional force after needle roller is withstood by spring sheet and between axle, 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 list pin spring sheet of the present invention;
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 solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, below with a preferred embodiment and accompanying drawing, technological scheme of the present invention 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 are processed into by sheet metal, 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 invention, 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 entirety, 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 reduced the frictional force after needle roller is withstood by spring sheet and between axle.Advantage is: one, because the spring sheet contacting with needle roller is single pin, therefore reduce starting torque, and reduce 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, frictional force after needle roller is withstood by spring sheet so and between axle strengthens, and in operation process, causes heating according to meeting, reduces the working life of bearing.The present invention have reduced needle roller and withstood by spring sheet after and frictional force between axle, meet client to bearing performance needs, improved the working life of bearing.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; everyly utilize equivalent structure or the equivalent flow process that specification of the present invention 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 invention.
