Description
Technical field
The present invention relates to a kind of gear drive, particularly relate to the transition gear mounting structure in the gear drive.
Background technique
Existing transition gear mounting structure; Comprise driving gear, transition gear and driven gear, said driven gear is driven through transition gear by driving gear and rotates, and said driving gear is driven by drive unit and rotates; That said active and passive gear is installed in respectively is main, by on the transmission shaft; This master, be rotationally connected through bearing and support plate respectively by transmission shaft, said transition gear is installed in the rotating shaft, and this rotating shaft is rotationally connected through 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 through the transitional function of transition gear.Though this transition gear mounting structure is simple; But defective aspect two below in processing and transmission process, existing; On the one hand, be to guarantee the transmission accuracy between driving gear, transition gear and the driven gear, that the rotary shaft hole that processing is used to install rotating shaft and bearing on support plate and processing are used to install is main, during by the master of transmission shaft and bearing, by the transmission axis hole; Must the said rotary shaft hole of strict guarantee and the master, by relative positional accuracy higher between the transmission axis hole; So not only increase difficulty of processing, processing cost and the production time of support plate greatly, but also increased reject rate, so that wasted great deal of raw materials; On the other hand; Owing to said rotary shaft hole and master, fixed by the relative position between the transmission axis hole; It is unadjustable after transition gear is installed in the said rotating shaft with the relative position of active and passive gear; Again since transition gear in the very easily wearing and tearing with active and passive meshed transmission gear simultaneously of when work, thereby this transition gear mounting structure is after using certain hour, usually the wearing and tearing owing to transition gear cause transmission accuracy to reduce greatly.
Summary of the invention
The technical problem that the present invention will solve provides a kind of difficulty of processing that can not only reduce support plate greatly, processing cost and shortens the production time, even and after the transition gear wearing and tearing, can also guarantee a kind of transition gear mounting structure of transmission accuracy.
For solving the problems of the technologies described above; The present invention adopts a kind of like this transition gear mounting structure; Comprise driving gear, transition gear and driven gear; Said driven gear is driven through transition gear by said driving gear and rotates, and said driving gear is driven by drive unit and rotates, and said active and passive gear and support plate are rotationally connected; Said transition gear is installed in the rotating shaft, and this mounting structure also comprises an elastic supporting mechanism that is used to adjust relative position between said transition gear and the said 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 the contiguous block of these bearing both sides regularly, is arranged on said contiguous block below and is fixedly connected with said support plate accordingly; Said Bearing Installation is in said rotating shaft; Offer a through hole on the little iron block of said supporting, the threaded end of said bolt passes said through hole and is threaded with said contiguous block; Said spring housing is contained on the said bolt and between said contiguous block and the little iron block of supporting.
In the present invention; Can offer a through hole on the said support plate; The both sides that this through hole places said support plate are passed in said rotating shaft, and said driving gear, transition gear and driven gear are positioned at a side of said support plate, and said elastic supporting mechanism is positioned at the opposite side of said support plate.
After adopting such structure, because the present invention is provided with an elastic supporting mechanism that is used to adjust relative position between transition gear and the active and passive gear, said elastic supporting mechanism preferably is made up of bearing, contiguous block, the little iron block of supporting, bolt and spring; When mounted; Twist said bolt through spanner; The bearing that makes bolt drive contiguous block and be fixed together with it moves towards active and passive gear direction; The transition gear that drives rotating shaft when said bearing moves and be installed in the rotating shaft moves towards active and passive gear direction simultaneously, can accurately control the accuracy of mesh between transition gear and the active and passive gear through the amount of movement of adjustment transition gear like this, thereby guarantees the transmission accuracy between driving gear, transition gear and the driven gear.This shows; The present invention is through adopting the relative position between elastic supporting mechanism adjustment transition gear and the active and passive gear; Can guarantee the transmission accuracy between driving gear, transition gear and the driven gear; Overcome in the existing technology and must could guarantee the defective of the transmission accuracy between driving gear, transition gear and the driven gear, so the present invention greatly reduce difficulty of processing, the processing cost of support plate and shorten the production time through strict guarantee rotary shaft hole and master, by high-precision relative position requirement between the transmission axis hole; But also reduced reject rate, saved great deal of raw materials.In addition; When behind the transition working gear certain hour and when wearing and tearing occurring; Only need to dwindle the distance between transition gear and the active and passive gear through said elastic supporting mechanism; Make transition gear and active and passive gear engagement fit better, and the transition gear that need not more to renew can guarantee the transmission accuracy between the three, produce and maintenance cost thereby greatly reduce.
As a kind of improvement of the present invention, said driving gear, transition gear and driven gear and said elastic supporting mechanism are positioned at the same side of said support plate.Adopt such structure, then on support plate, need not to offer again the through hole that is used for interspersed rotating shaft, thereby further reduced the difficulty of processing and the cost of support plate, and make the production time of support plate shorter.
As further improvement of the present invention; Described elastic supporting mechanism also comprises nuts and washers; Said nut is screwed on the said bolt, and said gasket sleeve is contained on the said bolt and places the bottom of said nut, and said spring is between said packing ring and the little iron block of supporting.Adopt such structure, only need on the one hand can shorten the use length of spring on the other hand through tightening or unscrewing said nut and can regulate the tension force between bearing and the little iron block of supporting easily, thus the use amount of saving spring.
