Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low and be convenient to process, be easy to the mounting structure of the novel The Cloud Terrace vertical drive shaft of installation and maintenance.
The technological scheme that the utility model is taked is:
A kind of mounting structure of novel The Cloud Terrace vertical drive shaft, comprise transmission shaft, optocoupler cover, setting sleeve, left bearing, right bearing, left riser, right riser and gearwheel, left and right riser respectively by left and right Bearing Installation on transmission shaft, on the transmission shaft of the outboard end of left riser, gearwheel is installed, its inboard end is installed the optocoupler cover, puts at optocoupler the optocoupler catch is installed; End is equipped with setting sleeve in the inboard of right riser, it is characterized in that: described transmission shaft is a cylindrical straight tube axle, radially is fixed with positioning retainer ring by made annular groove respectively on the straight tube axle of optocoupler cover and the inboard position of setting sleeve.
And described optocoupler cover, setting sleeve and gearwheel are all fixed by jackscrew and transmission shaft external peripheral surface.
And described transmission shaft is made one vertically and is walked line three-way hole, make at transmission shaft excircle middle part one with walk the wire outlet hole that line three-way hole is communicated with.
Advantage of the present utility model and good effect are:
1. this structure comprises transmission shaft, optocoupler cover, setting sleeve, left bearing, right bearing, left riser, right riser and gearwheel, and optocoupler cover and left bearing, setting sleeve and right bearing are all spacing by back-up ring.Wherein positioning retainer ring is the opening circlip, has played the effect of the shaft shoulder, has both made things convenient for the installing/dismounting of other parts, has reduced installation cost again, and is simultaneously safe and reliable.
2. the transmission shaft in this structure is a cylindrical straight tube axle, uses standard tubing or tube billet to be raw material, and cutting at one time is processed into, and has saved man-hour, has reduced difficulty of processing, has avoided existing multidiameter shaft to add the error in man-hour, has also saved raw material.
3. the utility model is simple in structure, design science is reasonable, profile is that the transmission shaft of cylindrical straight tube axle is easy to processing, unified outside dimension has guaranteed good stress distribution, the bulk strength height, and two positioning retainer rings and two risers cooperate with other parts and have realized transmission shafts spacing to radially, each parts that is sleeved on the transmission shaft excircle simultaneously can be adjusted angle of assembling flexibly, and what be provided with on the transmission shaft walks the installation that line three-way hole and wire outlet hole make things convenient for core of a cable.

Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of mounting structure of novel The Cloud Terrace vertical drive shaft, shown in Fig. 1～2, comprise transmission shaft 1, optocoupler cover 5, setting sleeve 14, left bearing 4, right bearing 15, left riser 3, right riser 13 and gearwheel 2, left and right riser respectively by left and right Bearing Installation on transmission shaft, on the transmission shaft of the outboard end of left riser, gearwheel is installed, its inboard end is installed the optocoupler cover, puts at optocoupler optocoupler catch 6 is installed; End is equipped with setting sleeve in the inboard of right riser, and innovation of the present utility model is: transmission shaft is a cylindrical straight tube axle, radially is fixed with positioning retainer ring by made annular groove respectively on the straight tube axle of optocoupler cover and the inboard position of setting sleeve.Make left annular groove 8 on the inboard straight tube axle of optocoupler cover, install location, left side ring washer 7 in this groove, make right annular groove 12 on the straight tube axle of setting sleeve inboard, install right location ring washer 11 in this groove.These two back-up rings are the opening circlip.Cooperating between two back-up rings and two annular grooves, played the effect of the shaft shoulder, both made things convenient for the installing/dismounting of other parts, reduced installation cost again, simultaneously safe and reliable.Setting sleeve and gearwheel are all fixed by jackscrew 16 and transmission shaft external peripheral surface, and the deck that the underpart of two risers installs is fixedlyed connected with other parts in the The Cloud Terrace.
In transmission shaft, make one vertically and walk line three-way hole 18, make at transmission shaft excircle middle part one with walk the wire outlet hole 10 that line three-way hole is communicated with.Wire harness 9 connects up in transmission shaft is walked line three-way hole and passes from wire outlet hole.
Assembling process of the present utility model is:
