Abstract
The utility model discloses a kind of wear-resisting type large torque freewheel clutches, including interior ring support and outer race, inner ring seat is located at the inner ring of outer race, and the inner ring of the outer race is equipped with card slot, the side of card slot offers deep-hole slot, and the inner wall of deep-hole slot is connected to one end of plunger by cylindrical spring.The utility model structure is simple, when interior ring support is rotated clockwise with respect to outer race, frictional force between stop roller and interior ring support, stop roller is driven to slide to the relatively narrow side of card slot, collective effect between stop roller, card slot and interior ring support three, realize that outer race and interior ring support rotate in same direction, when interior ring support is rotated counterclockwise relative to outer race, stop roller can slide to the wider side of card slot, due to lacking restraining force, realize that outer race and the movement of interior ring support are separated from each other, simultaneously as its wearability can be improved in the presence of wear-resistant block and wear rib.
Description
Technical field
The utility model relates to Clutch Technology field more particularly to a kind of wear-resisting type large torque freewheel clutches.
Background technique
Freewheel clutch is the development with electromechanical integrated product and the basic part occurred, it is for prime mover and work
Make between machine or power transmits the important component with separation function inside machine between driving shaft and driven shaft.It is using it is main,
The velocity variations of secondary part or the transformation of direction of rotation have the device of voluntarily clutch function；Existing clutch wearability compared with
Difference, and be once damaged replacement and be not easy.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the big torsion of a kind of wear-resisting type proposed
Square freewheel clutch.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of wear-resisting type large torque freewheel clutch, including interior ring support and outer race, inner ring seat are located at the inner ring of outer race,
The inner ring of the outer race is equipped with card slot, and the side of card slot offers deep-hole slot, and the inner wall of deep-hole slot is connected by cylindrical spring
It connecing in one end of plunger, the other end of plunger is connected to the side of curved splint, and the other side of curved splint is equipped with stop roller,
The inner wall of the card slot is removably connected with wear-resistant block.
Preferably, the card slot is equipped with mounting groove far from two inner walls of cylindrical spring, and the wear-resistant block is located at mounting groove
In, wear-resistant block is connected by the inner wall of screw and mounting groove.
Preferably, the outer ring of the stop roller is embedded with wear rib, wear rib at least there are five, and between multiple wear ribs
In being angularly distributed.
Preferably, the number at least three of the stop roller, and be in angularly to be distributed between multiple stop rollers.
Compared with prior art, the utility model has the beneficial effects that the utility model structure is simple, interior ring support is relatively outer
When seat ring rotates clockwise, frictional force between stop roller and interior ring support drives stop roller to slide to the relatively narrow side of card slot,
Collective effect between stop roller, card slot and interior ring support three realizes that outer race and interior ring support rotate in same direction, when interior ring support is opposite
When outer race rotates counterclockwise, stop roller can slide to the wider side of card slot, due to lacking restraining force, realize outer race and
Interior ring support movement is separated from each other, simultaneously as its wearability can be improved in the presence of wear-resistant block and wear rib.
Detailed description of the invention
Fig. 1 be the utility model proposes structural schematic diagram；
Fig. 2 is part A schematic enlarged-scale view in Fig. 1.
In figure: cylindrical spring 1, outer race 2, interior ring support 3, plunger 4, wear-resistant block 5, curved splint 6, stop roller 7, wear-resisting
Item 8.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of wear-resisting type large torque freewheel clutch, including interior ring support 3 and outer race 2, interior ring support 3 are located at
The inner ring of the inner ring of outer race 2, outer race 2 is equipped with card slot, and the side of card slot offers deep-hole slot, and the inner wall of deep-hole slot passes through
Cylindrical spring 1 is connected to one end of plunger 4, and the other end of plunger 4 is connected to the side of curved splint 6, curved splint 6 it is another
Side is equipped with stop roller 7, and the inner wall of card slot is removably connected with wear-resistant block 5, and card slot is one large one small structure.
Card slot is equipped with mounting groove far from two inner walls of cylindrical spring 1, and wear-resistant block 5 is located in mounting groove, and wear-resistant block 5 passes through
The connection of the inner wall of screw and mounting groove, is conveniently replaced, and improves wearability.
The number at least three of stop roller 7, and frictional force is improved in being angularly distributed between multiple stop rollers 7, into
And enhance brake force.
In this case, when the opposite outer race 2 of interior ring support 3 rotates clockwise, the frictional force between stop roller 7 and interior ring support 3,
Stop roller 7 is driven to slide to the relatively narrow side of card slot, collective effect between 3 three of stop roller 7, card slot and interior ring support is realized
Outer race 2 and interior ring support 3 rotate in same direction, and when interior ring support 3 is rotated counterclockwise relative to outer race 2, stop roller 7 can slide to card
Realize that outer race 2 and the movement of interior ring support 3 are separated from each other, simultaneously as wear-resistant block 5 due to lacking restraining force in the wider side of slot
Its wearability can be improved in presence with wear rib 8.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
