Description
Technical field
The axial safety device for being driven overload and generating is prevented the utility model relates to a kind of.
Background technique
When axial transmission, the case where axial load factor can be generated, easily integral device is damaged, therefore design a kind of axial direction
The generation of overload situations is effectively prevent in transmission, to protect to whole setting very necessary.
Summary of the invention
The axial safety device for being driven overload and generating is prevented the utility model proposes a kind of.
The utility model solves scheme used by technical problem, a kind of to prevent the axial safety dress for being driven overload and generating
It sets, including driving shaft, driven shaft, sleeve, hollow formation axis hole is set inside the driving shaft, the driven shaft front is elongated
Axle portion, rear portion are the thick axle portion that diameter is greater than elongated shaft, and elongate shift insertion axis hole is interior and can rotate relative to axis hole, and sleeve is arranged
In thick axle portion and driving shaft junction, the sleeve side is provided with the square hole of a connection sleeve inner, sets on front side of square hole
It is equipped with bayonet, forms step surface between bayonet and square hole, the driving shaft rear portion week lateral edge has been configured active pin shaft, main
Dynamic pin shaft is pierced by by square hole, and cylindrical cam portion is arranged in the sleeve rear portion, and the rear end face in cylindrical cam portion is provided with cam surface,
Thick axle portion side has been disposed radially driven pin shaft, and driving shaft front periphery is successively arranged with axle sleeve, spring, thrust from front to back
Bearing, axle sleeve are connected and fixed with driving shaft, and thrust bearing trailing flank is supported against sleeve, spring leading flank against axle sleeve, trailing flank
By thrust bearing.
Further, axle sleeve periphery is disposed radially the screw hole inside communicating the shaft sleeve, and lock-screw is arranged in screw hole,
Axle sleeve is through lock-screw and active shaft locking.
Compared with prior art, the utility model has the following beneficial effects: structure is simple, design rationally, can effectively be prevented
Only axial transmission overload.

Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Figs. 1-2, a kind of to prevent the axial safety device for being driven overload and generating, including driving shaft, driven shaft, set
Hollow formation axis hole is arranged in cylinder, the driving shaft inside, and the driven shaft front is elongate shift, and rear portion is greater than elongated for diameter
The thick axle portion of axis, elongate shift insertion axis hole is interior and can rotate relative to axis hole, and sleeve is set in thick axle portion and driving shaft junction,
The sleeve side is provided with the square hole of a connection sleeve inner, is provided with bayonet on front side of square hole, bayonet and square hole it
Between form step surface, the driving shaft rear portion week lateral edge has been configured active pin shaft, and active pin shaft is pierced by by square hole, described
Cylindrical cam portion is arranged in sleeve rear portion, and the rear end face in cylindrical cam portion is provided with cam surface, and thick axle portion side has been disposed radially
Driven pin shaft, driving shaft front periphery are successively arranged with axle sleeve, spring, thrust bearing, axle sleeve and active axis connection from front to back
Fixed, thrust bearing trailing flank is against sleeve, and spring leading flank is against axle sleeve, and trailing flank is against thrust bearing.
In the present embodiment, axle sleeve periphery is disposed radially the screw hole inside communicating the shaft sleeve, and locking screw is arranged in screw hole
Nail, axle sleeve is through lock-screw and active shaft locking.
In use, axle sleeve is fastened on actively after passing through the compressing force of mobile axle sleeve adjustment spring and pushing down thrust bearing
On axis, to make sleeve by pressure from left to right.Active pin shaft is caught in buckle, cam of the driven pin shaft against sleeve ends
Face, this pressure are born by the cam surface and driven pivot pin of square hole and active pivot pin and sleeve right end on sleeve, from
And the rotary motion of driving shaft is made to pass to driven shaft by sleeve and two pivot pins, it is in working condition at this time.
When the load increases, driven pivot pin is just cross over the top of cam surface, active pivot pin just slide into bayonet and square hole it
Between formed on step surface, so that driving shaft and driven shaft is detached from drive connection, form free state, thus play safeguard protection work
With being at this time overload protection state.
During remaining in operation, after the overload on driven shaft releases, under the action of the spring, device is by overloading
Guard mode is restored to working condition and continues to transmit power.
Above-listed preferred embodiment has been further described the purpose of this utility model, technical solution and advantage,
It should be understood that the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical
Within novel protection scope.
