Technical field
The present invention relates to a kind of transmission device with adaptation function.
Background technique
Transmission device (Transmission device) the transmission of power of power plant to the intermediate equipment of operation mechanism etc.The basic training of transmission system, with being the driving wheel that the power sent by motor passes to automobile, produces driving force, automobile can be travelled on certain speed.
Existing friction gearing in use, transmission device can not adjust automatically with load variations, so the adaptive capacity of existing transmission device to load is poor, when load changes, transmission device is often difficult to adapt to load, as when heavier loads, friction disk relative sliding and misplacing, makes whole transmission device quit work; When load is comparatively light, the frictional force between friction disk is still comparatively large, and friction disk easily damages.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of transmission device with adaptation function.
For achieving the above object, technological scheme of the present invention is:
There is the transmission device of adaptation function, comprise driving shaft, driven shaft, wherein, also comprise active friction cone pulley, driven friction cone pulley, stage clip and coarse thread nut, described driving shaft is coaxially fixedly connected with active friction cone pulley, described driven shaft and driving shaft are arranged vertically, driven shaft comprises path section and large footpath section, described driven friction cone pulley and stage clip are all set in path section, and stage clip one end and driven friction cone pulley offset, the conical surface of driven friction cone pulley and active friction cone pulley offsets, described large footpath section is provided with coarse thread in the side near path section, described coarse thread nut coordinates with the coarse thread in the section of large footpath, described stage clip offsets away from the end face of driven friction cone pulley one end and coarse thread nut one end.
When adopting technique scheme, when transmission device runs, driving shaft drives active friction cone pulley to rotate, because the conical surface of driven friction cone pulley and active friction cone pulley offsets, so active friction cone pulley drives driven friction cone pulley to rotate by frictional force, because driven friction cone pulley is connected to the path section of driven shaft, and one end of stage clip and driven friction cone pulley offset, the end face of the other end and coarse thread nut one end offsets, and driven friction cone pulley is crushed on active friction cone pulley.When the load on driven shaft is greater than specified value, then driven friction cone pulley and active friction cone pulley generation relative sliding, now the active friction cone pulley frictional force be applied on driven friction cone pulley is not enough to drive driven friction cone pulley synchronous axial system, and the rotational velocity of coarse thread nut is greater than the rotational velocity of driven shaft, so coarse thread nut moves axially along driven shaft, and stage clip is compressed further, the power that stage clip is applied on driven friction cone pulley increases, the positive pressure that same driven friction cone pulley is applied on active friction cone pulley increases, so the frictional force between active friction cone pulley and driven friction cone pulley increases, the rotating speed of final driven friction cone pulley is synchronous with active friction cone pulley, when the load on driven shaft reduces, the speed that active friction cone pulley drives driven friction cone pulley to rotate is larger, driven shaft and driven friction cone pulley synchronous axial system, and the rotational velocity of coarse thread nut is slightly less than the rotational velocity of driven shaft, with increase during load contrary, the relative driven shaft of coarse thread nut rotates backward, therefore coarse thread nut along driven shaft axially, and move away from the direction of driven friction cone pulley, so the decrement of stage clip reduces, stage clip is applied to the frictional force also corresponding reduction on driven friction cone pulley, positive pressure between same driven friction cone pulley and active friction cone pulley reduces, frictional force between the two reduces.When the load of the present invention on driven shaft changes, transmission device can have self-adjusting function, thus adapts to the load of Different Weight.
Further, described active friction cone pulley and driven friction cone pulley are equipped with thermal vias.Active friction cone pulley and driven friction cone pulley carry out transmission mainly through violent friction, can produce a large amount of heats in friction process, and thermal vias then can promote that heat distributes.
Further, described driven shaft is provided with radiator shutter.Radiator shutter has the effect of forced heat radiation, improves radiating effect.
Further, described driven friction cone pulley is connected with path paragraph key, and can slide axially along driven shaft.Can prevent in transmission process like this, driven friction cone pulley rotates relative to driven shaft.
