Description
Technical field
The utility model relates to a kind of clutches, more particularly to a kind of pearl posture freewheel clutch.
Background technique
Freewheel clutch is that power transmitting and isolated important component are realized between driving shaft and driven shaft.It is to utilize
The velocity variations of driving and driven part or the transformation of direction of rotation have the device of voluntarily clutch function.Existing freewheel clutch
Including the housing and ontology being connected, the end face of housing is located at the ontology side, and ontology is annular, sets on the internal perisporium of ontology
Be equipped with the groove for placing roller and pressure spring, groove has multiple and is uniformly distributed, due to existing reeded bottom wall, antetheca and
Rear wall is to be process on the body, and shape is complex, so that the broaching tool structure of broaching body upper groove is also more multiple
Miscellaneous, wire pulling method surplus is big, and processing efficiency is low and broaching tool is at high cost, and because the reason of groove antetheca and rear wall consumes ontology
Take that material is more, these all make the production cost of existing freewheel clutch higher.Moreover, because ontology inner circumferential space is limited,
The axis of pressure spring is longer, and the axis of pressure spring is perpendicular to roller, if being intended to by increasing roller quantity come the carrying of lifting clutch
Ability, roller quantity are limited.
To solve this problem, Chinese patent literature CN108561455A discloses a kind of torsion spring type freewheel clutch, including
Ontology, housing, roller and baffle, the housing and baffle are separately mounted to the two sides of ontology, and the ontology is annular, ontology
It is provided with roller slot on internal perisporium, roller is placed in roller slot, is provided with and roller phase between two adjacent rollers
Parallel torsional spring, the torsional spring are supported in mounting post set on housing, and the baffle is inserted into the front end of the mounting post
In upper set support holes, the torque arm of torsional spring and the rear end of previous roller offset.This torsional spring is supported on housing, on ontology
It can not have to the rear wall for processing bearing spring, eliminate the process for processing deep trouth on the body, it is only necessary to process shallower
Roller slot, process tool chipping allowance is small, and high in machining efficiency, cutter life is long, can reduce being produced into for product
This, it is often more important that in the case where ontology inner periphery restricted diameter, the quantity of roller can be increased, thus not increasing ontology
In the case of outer dimension, the bearing capacity of clutch is improved as far as possible.But this clutch, due to spring be supported on
In the thinner and longer spring mounting post of housing one bending forming, when further increasing the load of clutch, because of installation
The stability of column is short of, and will lead to spring and deflection occurs and prevent roller from according to the movement of scheduled track, roller can not be complete
Reach design runlength entirely, the reduction of roller impulse stroke causes clutch bearing capacity to decline.In addition, the two sides of ontology are respectively
The housing and baffle essentially identical with body peripheral diameter, housing include end plate and circumferential part, and housing circumferential part will coat chimeric
In the excircle of ontology, housing and baffle cover the two sides of ontology substantially, are unfavorable for the lubrication of ontology heat dissipation and roller, influence
The service life of clutch, and housing and baffle materials are more, and cost does not tend to decrease.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of pearl posture freewheel clutch, can accommodate compared with
More rollers, and can guarantee effective impulse stroke of roller, the bearing capacity of clutch is high, long service life.
To reach above-mentioned purpose, technical solution provided by the utility model is: a kind of pearl posture freewheel clutch, including
Ontology and roller, the ontology are annular, and roller-type face slot is provided on the internal perisporium of ontology, is placed in the slot of roller-type face
Roller, the two adjacent rollers are by spring intervals, and spring is mounted on the pearl frame mutually chimeric with ontology, and the spring applies roller
Add spring force and each roller is stuck in an inactive state between two springs；The pearl frame includes the first of ring plate shape
Side cover and the second side cover, first side cover is covered with second side is provided with opposite spring mounting post, and spring mounting post is flat
In the axis of the roller, each spring is installed in a pair of opposite spring mounting post row, first side cover and
Second side is covered to be additionally provided with claw and be inserted into the ontology by claw and be connected and fixed with ontology.
Each spring that the utility model is bonded with roller installs elastic supports, a pair of of bullet by a pair of of the spring being arranged on pearl frame
Spring mounting post covers opposite spring mounting post with second side by the first side cover and forms, and the length of each spring mounting post is not
Greater than the half of spring mounting hole length, spring mounting post long but also thin state not only, the intensity of spring mounting post are changed
It with rigidity height, is unlikely to deform, stability is strong, even if improving the load of clutch, mounting axis, that is, spring mounting post of spring
It is able to maintain reset condition, without because spring mounting post and the deflection of spring cause roller cannot be according to scheduled track
The problem of mobile, roller not fully reaches design runlength, and roller impulse stroke is reduced, and makes the decline of clutch bearing capacity.And
And constitute pearl frame the first side cover and the second side cover connected and fixed by claw and ontology, the outer diameter of the first side cover and the second side cover
As long as the diameter being distributed slightly larger than each spring mounting post, the installation site of the intensity and claw and ontology that can guarantee two side covers is i.e.
Can, the reduced diameter of the first side cover and the second side cover is conducive to the profit of ontology heat dissipation and roller without covering the two sides of ontology
It is sliding, improve the service life of clutch, also improve the globality of product appearance, and eliminate the more housing of former materials and
Baffle can be reduced materials, reduce production cost.
Further, to optimize structure, heat dissipation and the lubricant effect of clutch, the spring are improved in reasonable disposition space
