Abstract
The utility model discloses a novel loader overrunning clutch and belongs to the technical field of loader clutches. The novel loader overrunning clutch comprises an intermediate input shaft, an outer ring gear, an inner ring cam, a roller, a sliding block and a spring. The sliding block is arranged below the roller, a spring and a pin are inserted in a small hole in the inclined plane of the inner ring cam, one end of the pin abuts against one side of the sliding block, the other end of the pin is connected with the spring, an angle formed by the center line of the spring and the pin and the small plane of the upper plane of the inner ring cam is smaller than 10 degrees, and oil draining holes are formed at the back of each small hole in the periphery of the inner ring cam and penetrate the small plane of the upper plane of the inner ring cam upwards. The novel loader overrunning clutch reduces abrasion between parts and solves the problem of oil trapping of a spring pin hole.
Description
Technical field
The utility model belongs to loader Clutch Technology field, in particular to a kind of novel loader free wheel device.
Background technique
The free wheel device of generally applying at present, mainly formed by intermediate input shaft assembly, outer ring gear, roller and interior ring cam, at work roller through be everlasting wedging and unclamp between conversion, between roller and interior ring cam, be that line contacts, when wedging, contact stress exceedes allowable stress, easily causes extrusion-deformation part failure.Chinese patent CN2735072 discloses the large free wheel device of a kind of loader, and it has added slide block below roller, in the time of wedging, between roller and interior ring cam, is contacted and is changed into face contact by linearity, has reduced damage parts degree.But above-mentioned patented technology scheme medi-spring immediate roof is on slide block, and spring stress motion and overall structure are unreasonable.And the facet of prior art medi-spring center line and interior ring cam is approximately 13 degree angles, make the distance of motion between spring or pin and slide block or friction larger, in addition, in using process often because the chip in oil in gearbox or greasy filth cause the draining aperture clogs on pin center, aperture oil pocket pocketed oil, motion is obstructed, and causes part stress imbalance and damage inefficacy, has reduced the working life of free wheel device.
Summary of the invention
The purpose of this utility model is to solve the above problem, and existing loader free wheel device is transformed, and a kind of novel loader free wheel device of longer service life is provided.
The technical solution of the utility model is for achieving the above object:
A kind of novel loader free wheel device, comprises intermediate input axle, outer ring gear, interior ring cam, roller, slide block, spring, is provided with slide block below described roller; In aperture in described interior ring cam ramp, be inserted with spring and pin, one end of described pin withstands on a side of described slide block, and the other end is connected with spring, and the center line of described spring and pin and the facet angulation above described interior ring cam are less than 10 degree; Be provided with draining hole at each aperture rear portion of interior ring cam periphery, described draining hole is upward through the facet above interior ring cam.
Described slide block contacts with the interior ring cam facet below it.
Describedly be arranged on the spring in aperture and pin in interior ring cam ramp and have two covers.
Above structure of the present utility model, make the center line of pin and spring and the facet angulation above interior ring cam be less than 10 degree, it is minimum that thereby the distance that makes the fricting movement between pin and slide block reduces to, in addition, be easier to process draining hole at the rear portion of each aperture, solve spring pin hole pocketed oil problem.In a word, the utility model structure arrangement is reasonable, makes the motion of part more reasonable, thereby between part, minimum degree is down in friction, and the concrete structure having solved because increasing after slide block reaches an appropriate design difficult problem, has extended the working life of free wheel device.
Brief description of the drawings
Fig. 1 is the assembly structure schematic diagram of the utility model loader free wheel device;
Fig. 2 is the cut-away view of the utility model loader free wheel device;
Fig. 3 is the local structure for amplifying schematic diagram in circular dashed line in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, 2, 3: 1. roller, 2. slide block, 3. spring, 4. pin, 5. bearing, 6. spacer, 7. outer ring gear, 8. intermediate input axle, 9. nut, 10. bullet pad, 11. bolts, 12. left back-up rings, 13. interior ring cams, 14. right back-up rings.
It comprises intermediate input axle, outer ring gear, interior ring cam, roller, slide block, spring, pin; Below roller 1, increase slide block 2, in the concave circular arcs of roller 1 on slide block 2, slide block 2 contacts with the facet on interior ring cam 13 below, thereby roller 1 is contacted with 13, interior ring cam; In aperture on interior ring cam 13 periphery inclined-planes, be inserted with spring 3, spring 3 the other ends and pin 4 linearly link together, spring and pin and the interior ring cam facet angulation above it are less than 10 degree, and the other end of pin 4 withstands on adjacent sliders 2 sides, promote slide block 2 and roller 1 and slide; Each aperture rear portion on interior ring cam 13 periphery inclined-planes is provided with draining hole, and draining hole is upward through plane above.
In prior art, pin and spring and the interior ring cam facet below it are the angle of approximately 13 degree, the utility model makes pin and spring and the interior ring cam facet angulation above it be less than 10 degree, make the distance of the fricting movement between pin and slide block reduce to minimum, reduced the wearing and tearing between part.In addition, the aperture rear portion that the utility model inserts at spring processes draining hole, and draining hole upwards directly passes plane above, solves spring pin hole pocketed oil problem.
Claims (3)
1. a novel loader free wheel device, comprises intermediate input axle, outer ring gear, interior ring cam, roller, slide block, spring, is provided with slide block below described roller; It is characterized in that: in the aperture in described interior ring cam ramp, be inserted with spring and pin, one end of described pin withstands on a side of described slide block, the other end is connected with spring, and the center line of described spring and pin and the facet angulation above described interior ring cam are less than 10 degree; Be provided with draining hole at each aperture rear portion of interior ring cam periphery, described draining hole is upward through the facet above interior ring cam.
