Abstract
The utility model relates to a one-way clutch grease anti-seepage sealing structure. According to the technical scheme, the one-way clutch grease anti-seepage sealing structure is characterized in that the outer surface of a driving gear is sheathed with a guiding cylinder; the inner peripheral surface of the guiding cylinder is provided with a plurality of wedge-shaped grooves at intervals; the wedge-shaped grooves between the outer peripheral surface of the driving gear and the guiding cylinder form a plurality of ring-shaped wedge-shaped spaces; each ring-shaped wedge-shaped space is internally provided with a rolling column and a spring; and the ring-shaped wedge-shaped space is filled with lubricating grease. The one-way clutch grease anti-seepage sealing structure is characterized in that the inserting piece is positioned at the left end surface of the guiding cylinder; the sealing gasket is sealed outside the inserting piece; and the cover covers outside the sealing gasket and the left end of the guiding cylinder. The one-way clutch grease anti-seepage sealing structure has the advantages of: using the sealing gasket to cover the gap of the inserting piece, sealing the grease in the wedge-shaped grooves of the curved surface of the one-way clutch guiding cylinder, avoiding the grease from seeping earlier and prolonging the service life of a product.
Description
Technical field
The utility model relates to a class overrunning clutch grease sealed architecture advances, especially a kind of overrunning clutch grease antiseepage sealing configuration.
Background technique
Grease in the overrunning clutch curved surface plays a part key to the working life of overrunning clutch, and in use it not only will stand the test of high low temperature, and key also needs encapsulation preferably, can prevent from use not lose efficacy because of seepage.At present, the capping of domestic and international common overrunning clutch all adopts two semicircle inserted sheets to add the fixing structure of outer cover.The function of two semicircle inserted sheets, the one, the axial displacement of stationary drive gear, the 2nd, play seal grease.Because capping is made up of two semicircles, the centre certainly exists certain slit, and in use grease is easy to spill from the slit, because the too early leakage of grease, make lacking of actuation gear, roller and guide cylinder curved surface lubricated, cause overrunning clutch early failue to occur.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above, increases by a gasket seal in existing product.The sealing pad adopts oil resistant, the higher paper paper tinsel of intensity, and the sealing pad is covered on the two semicircle inserted sheets, has sealed the slit between the two semicircle inserted sheets, can effectively solve the phenomenon of grease from gap leakage.
According to the technical solution of the utility model, described overrunning clutch grease antiseepage sealing configuration, comprise actuation gear, cover cap, gasket seal, inserted sheet, roller, guide cylinder and spring, offer axis hole in the described actuation gear, the outside socket guide cylinder of actuation gear along its axial direction; Inner circumferential surface at guide cylinder is provided with several wedge-shaped impressions at interval; Wedge-shaped impression between actuation gear external peripheral surface and the guide cylinder has constituted the several ringlike wedge shape space, in each ring-type wedge shape space roller and spring is arranged; Filling lubricating grease in the described ring-type wedge shape space; It is characterized in that: described inserted sheet is positioned at the left side of guide cylinder; Described gasket seal is sealed in the outer surface of inserted sheet; Described cover cap covers on the left end outside of gasket seal and guide cylinder.
Described inserted sheet is two semi-annular shapes, and the inserted sheet of two semi-annular shapes is plugged in the left side of guide cylinder respectively; The inserted sheet junction point of two semi-annular shapes forms the slit; Described gasket seal is sealed on the slit.
Described gasket seal is the higher paper paper tinsel of oil resistant, intensity.
The utility model has the advantages that: on the roller-type one way clutch inserted sheet, covered the inserted sheet slit with gasket seal, grease in the overrunning clutch guide cylinder curved wedge shape groove is sealed, avoided the overrunning clutch too early seepage of grease in use, the working life of effectively having improved product.This gasket seal does not have influence substantially to product structure simultaneously, is convenient to extensive use.

Fig. 1 is a longitudinal section of the present utility model erection drawing.
Fig. 2 is guide cylinder, actuation gear, roller and spring connection diagram.
Embodiment
As shown in Figure 1, 2: 1, actuation gear, 2, cover cap, 3, gasket seal, 4, the semicircle inserted sheet, 5, roller, 6, guide cylinder, 7, spring, 8, the ring-type wedge shape space, 9, the slit.
Described overrunning clutch grease antiseepage sealing configuration comprises actuation gear 1, cover cap 2, gasket seal 3, inserted sheet 4, roller 5, guide cylinder 6 and spring 7, offers the axis hole along its axial direction on the actuation gear 1, the outside socket guide cylinder 6 of actuation gear 1; The external peripheral surface of described actuation gear 1 is provided with several wedge-shaped impressions at interval at the inner circumferential surface of guide cylinder 6; Wedge-shaped impression between actuation gear 1 external peripheral surface and the guide cylinder 6 constitutes several ringlike wedge shape space 8, places roller 5 and spring 7 in each ring-type wedge shape space 8; Filling lubricating grease in the described ring-type wedge shape space 8; For the axial displacement of stationary drive gear 1 and roller 5, the spring 7 in the ring-type wedge shape space 8, at the peg graft inserted sheet 4 of two semi-annular shapes of the end face of guide cylinder 6, because inserted sheet 4 is two semi-annular shapes, so form slit 9 at splicing position, for avoiding the grease in the ring-type wedge shape space 8 to spill from slit 9,9 places cover gasket seal 3 in the slit; Described gasket seal 3 is the higher paper paper tinsel of oil resistant, intensity, and gasket seal 3 is by cover cap 2 fixing seals, and cover cap 2 is fixed on the cylindrical and end face of guide cylinder 6.
9 places cover gasket seal 3 to the utility model in the slit, solved effectively grease from the slit 9 leakage problems, the working life of having improved product.This gasket seal does not have influence substantially to product structure simultaneously, is convenient to extensive use.
