Abstract
The invention relates to a one-way clutch of a split type structure. The one-way clutch comprises a sleeve, a blocking ring, a cover, a curve disk and a blocking piece, wherein a spiral spline is arranged on the inner hole wall of the sleeve, 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, an inner hole of the blocking ring is tightly matched with and fixed on the first outer step of the sleeve, a curve-shaped boss at the second outer step of the sleeve is matched with the curve surface of the curve disk, the outer circle of the blocking ring is matched with the curve surface of the curve disk, and the cover is in sleeve connection out the sleeve, the curve disk and the outer circle of the blocking piece. The sleeve and the curve disk are in the split type structure design, so that the one-way clutch is more convenient to install and dismount and lower in using cost. The sliding flexibility of the one-way clutch is greatly improved. When the one-way clutch is used, resistance is hardly felt in manual sliding. Furthermore, the noise is reduced.
Description
Technical field
The present invention relates to a kind of overrunning clutch, especially a kind of overrunning clutch of split-type structural.
Background technique
Make the material of splined sleeve in one-way element, 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 the individual, and the amount of miniature gasoline engine progressively enlarges, and technical requirements and quality are more and more higher.Because this petrol engine is that the 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, and some catching phenomena can not be arranged.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 objective of the invention is to overcome the deficiencies in the prior art, provide a kind of sleeve and curved discs to adopt Split type structure design, slippage overrunning clutch flexibly.
According to technological scheme provided by the invention, 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 the curve form at the second outer step place of sleeve matches with the curved surface of curved discs, 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 present invention, 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 the 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of middle sleeve of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
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 present invention, the boss of the curve form at the second outer step place of sleeve 1 and the curved surface of curved discs 4 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, be fixed together 1 sleeve, 2 packing rings, 4 curved discs, 5 catch and other part, guarantees that sleeve 1 and curved discs 4 are not loosening and axially unshift.
In the present invention, sleeve 1 use engineering nylon material is made, and the endoporus of sleeve 1 has helical spline and motor shaft spline to be complementary, and the large outer circular bosses of sleeve 1 becomes curve form and curved discs 4 shapes to be complementary, 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 be complementary.
Curved discs 4 use alloy steel materials are made, and it is designed to chip shape, and cylindrical is the 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, first be washed into basin shape, then be pressed in gear grooved by frock.
