Abstract
The utility model relates to a roller-type overrunning clutch of an outer star wheel for a loader, which belongs to the field of mechanical transmission. The utility model has the main technical characteristics that an external ring is of a star wheel type, a roller, a pressure spring, a top cap and a spring seat are arranged between an inner ring and the outer ring. The utility model has the advantages of reasonable structural design, simple manufacturing process and suitability for batch production. Due to the reduction of the centrifugal force of the roller, the roller-type overrunning clutch has the advantages of strong operational reliability, large torque, long service life, flexible disengagement and capability of long-time operation under the condition of high-speed heavy load.
Description
Technical field:
The utility model relates to a kind of free wheel device, relates in particular to a kind of loader out star wheel roller-type overrunning clutch, belongs to the mechanical transmission technical field.
Background technique:
Free wheel device has been widely used in the mechanical transmission technical field, and at present, the free wheel device that loader generally uses mainly is a star-wheel formula free wheel device.Though star-wheel formula clutch also is a roller type, its star-wheel processed complex, transmitting torque is less, and especially during the star-wheel high speed rotating, the centrifugal force that roller produces can't overcome, and therefore the complete machine quality to loader forms fatal influence.
Summary of the invention:
The purpose of this utility model just is a kind of reasonable in design is provided, and manufacturing process is simple, and functional reliability is strong, and bearing torque is big, the loader of long service life out star wheel roller-type overrunning clutch.
For achieving the above object, the utility model can be realized by following scheme: loader out star wheel roller clutch comprises outer ring gear (inner is the eccentric arc star wheel type), interior ring, roller, stage clip, top cap and spring seat.
The utility model is outer eccentric arc out star wheel roller clutch.
Spring seat, spring, top cap, roller circumference are corresponding one by one, evenly distribute, and between eccentric arc outer shroud star-wheel and interior ring.
Spring seat is embedded in the outer ring gear eccentric arc groove, and spring is loaded in the spring seat, front end dress crown cap.
Original state, spring apply certain starting force, during the work of active member forward, overcome spring power, can realize that forward surmounts; During the active member reverse operation, then the roller wedging in interior ring and outside between the eccentric arc, realize torsion pass.
The utility model has the advantages that: project organization is reasonable, and manufacturing process is simple, and functional reliability is strong, and bearing torque is big, long service life.Clutch can bear bigger moment of torsion and impact force, can work for a long time under the situation of high-speed overload.
Description of drawings:
Accompanying drawing one is the utility model overall structure schematic representation;
Accompanying drawing two is local enlarged diagrams in the utility model accompanying drawing one circle.
Embodiment:
Now in conjunction with the accompanying drawings the utility model is described in further detail:
The utility model comprises: the back-up ring of ring, (2) axial limiting, (3) outer ring gear (inner is the eccentric arc star-wheel), (4) spring seat in (1), support spring to give certain starting force, (5) stage clip of roller, (6) top cap, (7) roller, be evenly distributed on the circumference, by the even application of force of stage clip, make that roller is realized on the eccentric arc freeing outside, wedging.The utility model changes primary plane star-wheel roller clutch into eccentric arc out star wheel clutch, and the big free wheel device bearing torque that loader is used increases substantially.The characteristics of the utility model maximum are to free freely, reliable operation, because angle of wedge variation is less, prolong working life, effectively solved loader and existed moment of torsion little with free wheel device, the problem that the life-span is short.
Claims (2)
1, loader out star wheel roller-type overrunning clutch, comprise that outer ring gear is eccentric arc star wheel structure (3), interior ring (1), it is characterized in that: be provided with roller (7) between outer ring gear (3) and the interior ring (1), roller applies starting force by stage clip (5), stage clip is contained in that spring seat (4) is gone up, spring front end dress crown cap (6), spring seat are set on the outer ring gear (3).
2, a kind of loader speed reducer out star wheel roller-type overrunning clutch as claimed in claim 1, it is characterized in that outer ring gear (3) endoporus is a star-wheel, inside is roller type, star-wheel designs for eccentric arc, outer shroud studs with stage clip (5) and top cap (6) is housed on spring seat (4), the spring seat, guarantees the clutch wedging or surmounts.
