Detailed description of the invention
Fig. 1 is utility model diagram.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
As shown in Figure 1, a kind of drive steering shaft rotating mechanism is mainly by clamp system 1, angle positioning 2, carrying
Bracket 3, driving motor 4, retarder 5, lever case 6, carrying roller 7, positioning screw 8, rotating mechanism length are 300mm, and width is
The characteristics of 40mm is highly 175mm, and the diameter of clamp system 1 is 150mm, due to the self structure of steering shaft is cylindrical body, because
This carries out head and the tail both ends using detachable clamp system 1 and fixes, and wherein clamp system 1 is assembled by four arcs section, and two
Duan great Yuan segmental arc respectively has a spill platform outstanding, matches with the outer surface of steering shaft, the clamping for steering shaft is fixed, recessed
Shape platform surface covers one layer of epoxide resin material, and such material property is excellent, and bending stiffness performance is good, soft or hard to be applicable in, Ke Yitong
Certain deformation is crossed to provide holding power, while the scuffing to steering shaft surface can be ensured against, is that a kind of application is extremely wide
There are threaded hole in general material, two sections of roundlet segmental arc middle sections, can be connected by installation holding screw with the positioning of steering shaft
Contact is connected, and further steering shaft is fixed, and four arcs section is by the cube block equipped with bolt come the company of being fixed
It connects, the fixation of cube block and arc section is realized by installing the bolt of vertical direction, outer surface of clamp system 1 or so is each
There are two gear ring identical with perimeter with the radian of four arcs section, clamp systems 1 to be propped up by two symmetrical carrying rollers 7 for dress
Support, while the gear ring on 7 surface of carrying roller and 1 surface of clamp system are intermeshed, motor imparts power to support by retarder
Roller 7, carrying roller 7 drive clamp system 1 to be rotated, along the circumferential direction revolve to realize steering shaft by gear engaged transmission
Turn.
While realizing that steering shaft clamp system 1 rotates, need in view of its axial limiting, to guarantee in rotary course
Safety, therefore with reference to roller bearing working principle and structure design basis on, most by the side of clamp system 1
Large circle week, strong point processed one and half ball grooves, while installing a small-sized lever case 6, lever in the middle of load support 3
Top is identical with half ball groove diameter hemisphere, and before the rotation of motor driven steering shaft, lever case 6 moves so that lever
Top meets with half ball groove, so not only can be while not influenced steering shaft rotation, but also can play the role of axial restraint, but
It is the effect only by lever case 6 or can not reach requirement, therefore there are two fixed for installation at the both ends of load support 3
Position screw rod 8 can be such that angle positioning 2 moves to apart from the suitable position of clamp system 1 by the spinning in and out of screw rod,
Angle positioning 2 is equipped with locking pliers, idler wheel is housed on the top of locking pliers, by the closure of locking pliers so that left and right idler wheel
It is contacted with steering shaft clamp system 1, with the rotation of clamp system 1, idler wheel can also be rotated with it, and will not be caused to rotary motion
It influences, while also clamp system 1 can be limited and be fixed.
