Abstract
The utility model relates to a large overrunning clutch for loader, which relates to a roller type large overrunning clutch in an epicyclic gearbox of a loader, and basic elements are an intermediate input axis, an inner race cam, a roller and an external ring gear wheel. The utility model is characterized in that a slide block is increased under the roller. When it is in wedge-caulking, the line contact between the roller and the inner race cam is changed into the surface contact, decreasing contact stress and solving the main cause of damage, and thus solving the quality bottleneck of the national epicyclic gearbox of the loader.
Description
Technical field
The utility model relates to the big free wheel device of roller type in the loader planetary transmission, and basic building block is middle input shaft, interior ring cam, roller and outer ring gear.
Background technique
At present the big free wheel device of loader adopts is that roller is realized clutch function by the mode of wedging repeatedly between interior ring cam and outer ring gear.During wedging, contact stress height between roller and the interior ring cam, the working surface collapse-deformation of ring cam and roller distortion and wearing and tearing damage big free wheel device in causing, and working life is short.
Summary of the invention
The purpose of this utility model provides a kind of big free wheel device of loader of longer service life.The utility model is to realize like this, between roller and interior ring cam, increase slide block, roller contacts with the slide block intrados, and slide block and interior ring cam are plane contact, by wedging the time, make between roller and the interior ring cam to contact and make into now neither to change original function and character, the contact stress when having reduced wedging again by the face contact of slide block transition from line.And it is similar to the rolling bearing working condition when non-wedging.

1. outer ring gears among the figure, 2. interior ring cam, 3. roller, 4. slide block, 5. isolating frame, 6. spring, 7. spring, 8. input shaft.
Embodiment
To the big free wheel device of domestic two kinds of representative types, according to said method improvement at present.A kind of is the big free wheel device of traditional band isolating frame, be to install slide block (4) additional below the roller (3) between outer ring gear (1) and interior ring cam (2), the groove surface that is slidingly matched mutually with roller (3) is arranged on the slide block (4), roller (3) is placed in each rectangular hole slot of isolating frame (5) with slide block (4), is held out against in middle input shaft (8) by 3 springs (6) again. and between the isolating frame (5).
Another kind is improved traditionally in the above, mainly be that Hangzhou (Hangzhoupro tooth and army's connection) produces, be to install slide block (4) additional below the roller (3) between outer ring gear (1) and interior ring cam (2), the groove surface that is slidingly matched mutually with roller (3) is arranged on the slide block (4), 2 springs (7) are installed between every group of roller (3) and slide block (4) and interior ring cam (2), when making the two ends wedging of roller (3) stressed evenly, thereby saved isolating frame.
The utility model structure is uncomplicated, mainly increases a kind of of slide block, and cost increases few, selects suitable parameters and size, can realize than being easier to.
When loader is in the low-speed heave-load operating mode, interior ring cam (2) rotating speed is during less than the rotating speed of outer ring gear (1), and roller between them (3) and slide block (4) are by wedging; When loader is in the high speed light loading operating mode, interior ring cam (2) rotating speed is higher than the rotating speed of outer ring gear (1), just unclamps between roller (3) and the slide block (4).
Claims (3)
1. big free wheel device of loader, its main member has middle input shaft (8), interior ring cam (2), roller (3), isolation mounting, outer ring gear (1), spring assembly to form, and it is characterized in that: install slide block (4) additional between roller (3) and interior ring cam (2).
2. the big free wheel device of a kind of loader according to claim 1 is characterized in that: isolation mounting is by isolating frame (5), and an end of spring (6) withstands on the isolating frame (5), and the other end withstands on the middle input shaft (8).
3. the big free wheel device of a kind of loader according to claim 1 is characterized in that: isolation mounting is a mounting spring (7) between each slide block (4) and interior ring cam (2).
