Description
Technical field
The present invention relates to a kind of gear drive, particularly relate to the transition gear installation structure in gear drive.
Background technique
Existing transition gear installation structure, comprise driving gear, transition gear and driven gear, described driven gear drives rotation by driving gear by transition gear, described driving gear is driven and is rotated by drive unit, described active and passive gear is arranged on respectively master, is transmitted on axle, this master, be transmitted axle and by bearing and support plate, be rotationally connected respectively, described transition gear is arranged in rotating shaft, and this rotating shaft is rotationally connected by bearing and support plate.When transmission, driving gear makes the sense of rotation of driven gear identical with the sense of rotation of driving gear by the transitional function of transition gear.Although this transition gear installation structure is simple, but defect aspect two below existing in processing and transmission process, on the one hand, for guaranteeing driving gear, transmission accuracy between transition gear and driven gear, on support plate, processing is for installing the rotary shaft hole of rotating shaft and bearing and processing for master is installed, be transmitted the master of axle and bearing, while being transmitted axis hole, rotary shaft hole and master described in necessary strict guarantee, be transmitted relative positional accuracy higher between axis hole, so not only greatly increased the difficulty of processing of support plate, processing cost and production time, but also increased reject rate, so that a large amount of raw material have been wasted, on the other hand, because described rotary shaft hole and master, the relative position that is transmitted between axis hole are fixed, it is unadjustable with the relative position of active and passive gear after transition gear is arranged in described rotating shaft, again due to transition gear very easily wearing and tearing with active and passive meshed transmission gear simultaneously when working, thereby this transition gear installation structure is after being used certain hour, usually the wearing and tearing due to transition gear cause transmission accuracy greatly to reduce.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of difficulty of processing that can not only greatly reduce support plate, processing cost and shortens the production time, even and after transition gear wearing and tearing, can also guarantee a kind of transition gear installation structure of transmission accuracy.
For solving the problems of the technologies described above, the present invention adopts a kind of like this transition gear installation structure, comprise driving gear, transition gear and driven gear, described driven gear drives rotation by described driving gear by transition gear, described driving gear is driven and is rotated by drive unit, described active and passive gear and support plate are rotationally connected, described transition gear is arranged in rotating shaft, and this mounting structure also comprises that one for adjusting the elastic supporting mechanism of relative position between described transition gear and described active and passive gear.
As a kind of preferred implementation of the present invention, the little iron block of supporting, bolt and spring that described elastic supporting mechanism comprises bearing, symmetry and is arranged on regularly the contiguous block of these bearing both sides, is arranged on described contiguous block below and is fixedly connected with described support plate accordingly; Described bearing is arranged in described rotating shaft; On the little iron block of described supporting, offer a through hole, the threaded end of described bolt is threaded with described contiguous block through described through hole; Described spring housing is contained on described bolt and between described contiguous block and the little iron block of supporting.
In the present invention, on described support plate, can offer a through hole, described rotating shaft is placed in the both sides of described support plate through this through hole, described driving gear, transition gear and driven gear are positioned at a side of described support plate, and described elastic supporting mechanism is positioned at the opposite side of described support plate.
Adopt after such structure, because the present invention is provided with one for adjusting the elastic supporting mechanism of relative position between transition gear and active and passive gear, described elastic supporting mechanism preferably consists of bearing, contiguous block, the little iron block of supporting, bolt and spring; When mounted, by spanner, twist described bolt, the bearing that makes bolt drive contiguous block and be fixed together with it moves towards active and passive gear direction, described bearing drives rotating shaft and is arranged on transition gear in rotating shaft and towards active and passive gear direction, moves simultaneously while moving, by adjusting the amount of movement of transition gear, can accurately control the accuracy of mesh between transition gear and active and passive gear like this, thereby guarantee the transmission accuracy between driving gear, transition gear and driven gear.As can be seen here, the present invention is by adopting elastic supporting mechanism to adjust transition gear and active, relative position between driven gear, can guarantee driving gear, transmission accuracy between transition gear and driven gear, having overcome must be by strict guarantee rotary shaft hole and master in prior art, be transmitted high-precision relative position requirement between axis hole, guarantee driving gear, the defect of the transmission accuracy between transition gear and driven gear, therefore the present invention greatly reduces the difficulty of processing of support plate, processing cost has also shortened the production time, but also reduced reject rate, a large amount of raw material have been saved.In addition, while there are wearing and tearing after transition working gear certain hour, only need dwindle the distance between transition gear and active and passive gear by described elastic supporting mechanism, make transition gear and active and passive gear engagement fit better, and can guarantee the transmission accuracy between three without the transition gear more renewing, thereby greatly reduce, produce and maintenance cost.
As a modification of the present invention, described driving gear, transition gear and driven gear and described elastic supporting mechanism are positioned at the same side of described support plate.Adopt such structure, on support plate without offering again for interting the through hole of rotating shaft, thereby further reduced difficulty of processing and the cost of support plate, and made the production time of support plate shorter.
As a further improvement on the present invention, described elastic supporting mechanism also comprises nuts and washers, described nut is screwed on described bolt, and described gasket sleeve is contained on described bolt and is placed in the bottom of described nut, and described spring is between described packing ring and the little iron block of supporting.Adopt such structure, only need on the one hand can regulate easily the tension force between bearing and the little iron block of supporting by tightening or unscrewing described nut, can shorten on the other hand the use length of spring, thus the use amount of saving spring.
