Abstract
The utility model relates to a one-way clutch of a split type structure. The one-way clutch comprise a sleeve, a check ring, a cover cap, a curved surface disc and a stop sheet, wherein the inner hole wall of the sleeve is provided with a spiral spline, the sleeve is provided with a first outer step and a second outer step, the second outer step of the sleeve is arranged outside the first outer step of the sleeve, an inner hole of the check ring and the first outer step of the sleeve are fixed in a close fit mode, a boss, in a curved surface shape, on the second outer step of the sleeve is matched with the curved surface of the curved surface disc, an outer circle of the check ring is matched with the curved surface of the curved surface disc, the cover cap is connected outside the sleeve, the curved surface disc and the outer circle of the stop sheet in a sleeved mode. The split structure design is adopted for the sleeve and the curved surface disc, so that the one-way clutch is assembled and disassembled more conveniently, and using cost is lower; sliding flexibility of the one-way clutch is greatly improved, when using the one-way clutch, a user almost feels no resistance in the manual sliding process, and noise is lowered.
Description
Technical field
The utility model relates to a kind of overrunning clutch, especially a kind of overrunning clutch of split-type structural.
Background technique
In one-way element, make the material of splined sleeve, the noise that the slippage flexibility for one-way element on splined shaft and slippage produce plays an important role.At present, what domestic and international most of one-way elements adopted is the structure of sleeve and curved discs one, and is made with alloyed steel.Along with the raising of national economy and living standards of the people, the progressively prosperity of show business and environmental protection industry is got up.Yacht and mowing machine are progressively had by individual, and the amount of miniature gasoline engine progressively expands, and technical requirements and quality are more and more higher.Because this petrol engine is that artificial hand pull-up is moving, one-way element moves axially engagement by inertia.Slippage requirement on flexibility to one-way element is very high, can not have some catching phenomena.With original sleeve and curved discs integrative-structure, adopt alloy steel material to make, through test of many times, can not meet technical requirements.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of sleeve and curved discs to adopt Split type structure design, slippage overrunning clutch flexibly.
The technological scheme providing according to the utility model, the overrunning clutch of described split-type structural, comprise sleeve, back-up ring, cover cap, curved discs and catch, the inner hole wall of described sleeve has helical spline, sleeve has the first outer step and the second outer step, the second outer step of sleeve is arranged on the first outer step outside of sleeve, the first outer step close-fitting of the endoporus of back-up ring and sleeve is fixed, the boss of curve form and the curved surface of curved discs at the second outer step place of sleeve match, the cylindrical of back-up ring matches with the curved surface of curved discs, at sleeve, the cylindrical outer cover of curved discs and catch is connected to cover cap.
The cylindrical of described catch is concordant with the cylindrical of curved discs.
Large 2 ~ the 3mm of combined overall thickness of depth ratio sleeve, curved discs and the back-up ring of described cover cap.
Described sleeve is made by engineering nylon.
Described curved discs is made by alloyed steel.
In the utility model, due to sleeve and the design of curved discs employing Split type structure, make the installation and removal of overrunning clutch become convenient, user cost is lower; And sleeve has adopted engineering nylon making, its friction ractor is reduced to 0.02 by original 0.1, makes sleeve and rotor axis of electric move frictional resistance and is decreased to 1/5, greatly improved the slippage flexibility of overrunning clutch, during use, manual slippage is imperceptible resistance almost, and has reduced noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of the utility model middle sleeve.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
The overrunning clutch of this split-type structural, comprise sleeve 1, back-up ring 2, cover cap 3, curved discs 4 and catch 5, the inner hole wall of described sleeve 1 has helical spline, sleeve 1 has the first outer step and the second outer step, the second outer step of sleeve 1 is arranged on the first outer step outside of sleeve 1, the first outer step close-fitting of the endoporus of back-up ring 2 and sleeve 1 is fixed, the boss of the curve form at the second outer step place of sleeve 1 matches with the curved surface of curved discs 4, the cylindrical of back-up ring 2 matches with the curved surface of curved discs 4, at sleeve 1, curved discs 4 is connected to cover cap 3 with the cylindrical outer cover of catch 5.
The cylindrical of described catch 5 is concordant with the cylindrical of curved discs 4.
Large 2 ~ the 3mm of combined overall thickness of the depth ratio sleeve 1 of described cover cap 3, curved discs 4 and back-up ring 2.
Described sleeve 1 is made by engineering nylon.
Described curved discs 4 is made by alloyed steel.
In the utility model, the boss of curve form and the curved surface of curved discs 4 at the second outer step place of sleeve 1 are inlayed, and the first outer step close-fitting of the endoporus of back-up ring 2 and sleeve 1 is fixed, and the cylindrical of packing ring 2 and 4 curved discs curved surfaces are inlayed.Catch 5 is a ring washer that is pressed in advance the gear diameter of axle, the external diameter of catch 5 is concordant with 4 curved discs, cover cap 3 riveting buttons for cylindrical, are fixed together 1 sleeve, 2 packing rings, 4 curved discs, 5 catch and other part, guarantee that sleeve 1 and curved discs 4 are not loosening and axially unshift.
In the utility model, sleeve 1 use engineering nylon material is made, and the endoporus of sleeve 1 has helical spline and motor shaft spline to match, and the large outer circular bosses of sleeve 1 becomes curve form and curved discs 4 shapes to match, and it can be shaped with mould on common molding machine processed.
The chill steel plate materials punching press of back-up ring 2 use 50# is made, and the cylindrical of back-up ring 2 becomes curve form and curved discs 4 shapes to match.
Curved discs 4 use alloy steel materials are made, and it is designed to chip shape, and cylindrical is light circle, and bore design becomes curved surface, and curved surface can be broached or cold-extruded.
Catch 5 use 50# chill plate materials processings, are first washed into basin shape, then are pressed in gear grooved by frock.
