Abstract
An overrunning clutch device for an output shaft of a speed reducer integrates an overrunning mechanism, a shaft and a gear. A plurality of wedge grooves are arranged between a shaft and a gear, each wedge groove is composed of a gear arc surface and an oblique conical surface of the outer diameter of an output shaft, and a gap at one end of each wedge groove is small while a gap at the other end of each wedge groove is large. The wedge groove is provided with a roller, a spring and a top pin. When the gear rotates anticlockwise, the roller enters the small gap of the wedge groove to clamp the output shaft to rotate together; when the gear stops rotating, the output shaft still rotates to the original direction, the roller exits from the small gap of the wedge groove, the large gap at the other end of the wedge groove is propped by the spring and the jacking pin to slide, the output shaft is automatically separated from the gear, and the shaft exceeds the gear to rotate. The device is applied to the speed reducer, if the mechanism is damaged, the gear does not rotate, the shaft can rotate as is, and the normal operation of the whole machine is not influenced.
Description
The utility model is to make a kind of overrunning clutch in the output shaft of speed reducer and gear.
Do not have engaging and disengaging gear between existing speed reducer output shaft and the gear, adopt key connecting between gear and the axle, form secure fit, with changeing with stopping.On roller bed conveying line, certain driving is with breaking down in the speed reducer with speed reducer for speed reducer, particularly roller-way, if gear does not change, axle does not change yet, and the slow speed turbine stage gear that output shaft connects with it can not separate, and the whole piece conveyor line is subjected to speed reducer output shaft transmission restriction and can not runs well.
Existing overrun is not an one with axle, gear, because the speed reducer compact structure is not suitable for assembling and uses.
Also having a kind of one-way clutch, as the chain rear tooth disk of bicycle, belong to the pawl type clutch mechanism, is to adopt tooth type structures, and what tooth was flat one can slide, and the side that tooth is straight does not slide, the formation one-way clutch.Pawl type clutch mechanism and overrunning clutch mechanism are different, do not have to find that the axle that is applied to dynamic power machine uses with gear intercropping transmission and clutch at present.
The purpose of this utility model is to make a cover overrunning clutch between the gear on output shaft and the axle.
The utility model adopt gear with spool connect outside make several wedge slot, the wedge groove is made up of the tilted conical surface of gear arc surface and output shaft top external diameter, wedge groove one splaying is little, a splaying is big, in the wedge groove roller is arranged.
The utility model adopts and make wedge groove and roller between axle and gear, when roller when the little gap location of wedge groove blocks, axle together rotates with gear; When roller during at the big gap location of wedge groove, roller slides, and axle surmounts gear and separates.This making and settlement scheme uses the one-way element of wedge groove and roller to combine together between axle and gear, and axle is separated automatically with gear.Use on speed reducer, if mechanism damages, gear does not change, and axle can rotate in the same old way, does not influence the normal operation of complete machine.
Following example is described further with embodiment shown in the drawings:
Accompanying drawing is a roller-way speed reducer output shaft overrunning clutch schematic representation, and the inner ring of gear shown in the figure [1] is a circular arc, is output shaft [6] in the gear [1].Be equipped with several wedge slot [5] on the axle external diameter that output shaft [6] contacts with gear [1], wedge groove [5] is formed through last tilted conical surface by gear [1] inner ring arc surface and axle are outer.Wedge groove [6] one splayings are big, and a splaying is little.Roller [2] is housed in wedge groove [5], ejector pin [3] and spring [4] is housed at the big gap location of the other end of wedge groove [5].There is plate washer [7] outside, and the energy shelves are lived roller [2] and do not come out.When gear [1] counterclockwise rotation, drive little gap location that roller [2] enters wedge groove [5] and block output shaft [6] and rotate together; When gear [1] stall, still to counterclockwise direction (former direction) rotation, roller withdraws from the little gap location of wedge groove [5] to output shaft [6], withstands slip at the big gap location of wedge groove [5] the other end by spring [4], ejector pin [3], output shaft [6] separates automatically with gear [1], and axle [6] surmounts gear [1] rotation.That is: gear [1] stall, axle [6] are still being changeed, and gear [1] becomes to surmount the disengaging clutch state with axle [6].
This embodiment uses on log transporting dams machine roller bed conveying line, cuts off certain speed reducer power supply test through doing, and complete machine runs well, and timber still was transferred the dam.
