Description
technical field:
the utility model relates to electrical generator fields, particularly relates to the transmission system of generator.
background technique:
in engine driving system, power is delivered on driving gear by driving shaft, drive described driven tooth to rotate by described driving gear again, described driven gear rotates thus drives drive axis, and last described transmission shaft is rotated is delivered to (as tire, propeller cavitation etc.) on rotating member.
In existing driven tooth, often by the clutch sheathed for described rotating member, then be located on described transmission shaft by described clutch sleeve, described clutch is connected with described splined driveshaft.When described rotating member is in the process of motion, if receive the impact of external force, this impact force just can be delivered on described transmission shaft by described clutch, described clutch just can produce a power contrary with described transmission shaft sense of rotation, thus in order to avoid impacting driving shaft, just can there is " skidding " phenomenon with described transmission shaft in described clutch, described transmission shaft provides power just no longer can to described rotating member, and the phenomenon that dallies will occur described rotating member.
Occur that idle running phenomenon will cause the situation of rotating member stall, no matter at automotive field or aviation field or navigational field, will the danger that cannot estimate be there will be.
model utility content:
the purpose of this utility model is to provide a kind of buffer structure for engine driving system can avoiding idle running phenomenon.
To achieve these goals, the utility model is achieved in that a kind of buffer structure for engine driving system, comprise transmission shaft and driven tooth, also comprise resilient member and stop wheel hub, described resilient member, stop wheel hub and driven tooth are set on described transmission shaft successively; Wherein, described driven gear and described transmission shaft are Spielpassung, and described stop wheel hub circumference is fixed on described transmission shaft, and described resilient member and described transmission shaft are Spielpassung, are curved face contact between described stop wheel hub and described driven tooth.
Sheathed described resilient member, stop wheel hub and described driven tooth successively on described transmission shaft, can avoid occurring " skiddings " when rotating member receives external impacts time and to dally phenomenon.
When transmission system normally works, described follower rotates forward, owing to being curved face contact between described follower and described stop wheel hub, thus drive described stop wheel hub to rotate forward, and described stop wheel hub and described transmission shaft axial restraint, described transmission shaft then can be driven to rotate forward, and then the rotating member be connected with described transmission shaft is rotated forward.When described rotating member is subject to the impact of external force, stop wheel hub and driven tooth generation relative movement, play buffer function, due between described transmission shaft with described stop wheel hub for curved surface is connected, an axial rebounding force can be produced when described stop wheel hub reversion, this axial rebounding force is passed to resilient member and is absorbed by resilient member, and after absorbing, described transmission shaft continues to drive described stop wheel hub to rotate forward, thus drives described rotating member proper motion.Both protect bent axle, turn avoid the danger of rotating frame generation skid.
In order to make to optimize described curved surface further, the curved surface A that the end face of described stop wheel hub is formed for having the ratchet A that extends in the axial direction, the end face of described driven tooth is the curved surface B with the ratchet B coordinated with described ratchet A.
In order to increase stability further, described ratchet A and described ratchet B has three respectively and is evenly distributed on the end face of stop wheel hub and the end face of driven tooth.
Better in order to make at cushioning effect further, between the side of described ratchet A and the side of described ratchet B, there is space, between the bottom surface of described ratchet A and the end face of described ratchet B, there is gap.
In order to make structure compacter further, the gap between the bottom surface of described ratchet A and the end face of described ratchet B is 0.9-1.1mm.
Preferably, described resilient member is spring structure.
Preferably, described resilient member is for playing mat structure.
In order to make cushioning effect better further, be provided with clutch at described stop wheel hub overcoat.
The beneficial effects of the utility model are: adopt buffer structure of the present utility model, can, when rotating member receives external impacts, bent axle can either be protected not come to harm, can also avoid the dangerous phenomenon of rotating member generation skid.
