Abstract
The utility model discloses a worm and wheel-worm transmission device with adjustable transmission clearance. The transmission device comprises a transmission box; a worm wheel and a worm matched with each other, and a main shaft for mounting the worm wheel are arranged in the transmission box; one end of the main shaft is movably arranged in a main eccentric sleeve, and the other end thereof is movably arranged in a support eccentric sleeve matched with the main eccentric sleeve; and both the main eccentric sleeve and the support eccentric sleeve are arranged on the transmission box. The transmission device changes the wheelbase between the main shaft and the worm through rotating the main eccentric sleeve and the corresponding eccentric sleeve, so as to remedy the transmission clearance resulting from processing and assembly errors of the worm wheel and the worm, and conduct clearance compensation on abrasions caused during pre-running and/or normal use, thereby increasing the contact area between the worm wheel and the worm, improving the load bearing ability and the transmission precision of the worm wheel, and greatly prolonging the service life of the worm wheel and the worm.
Description
Technical field
The utility model relates to a kind of transmission device, refers more particularly to a kind of worm gearing.
Background technique
As everyone knows, error is difficult to avoid in the processing of worm and gear and assembling, and this just makes and has drive gap between the worm and gear.In order to reduce drive gap as much as possible, traditional solution is to improve processing and assembly precision.But this method can increase the fabricating cost of worm and gear greatly, and, mostly under the situation, worm and gear need to run in advance and, run and can strengthen drive gap usually afterwards.And drive gap is excessive, can reduce the area of contact of worm and gear, reduces the load ability to bear of worm gear, greatly reduces the transmission accuracy of worm and gear, shortens its working life.
The model utility content
Technical problem to be solved in the utility model is: a kind of worm gear having adjustable gearing clearance is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: worm gearing, comprise: transmission case, the main shaft that is provided with the worm gear that cooperatively interacts and worm screw in the transmission case and worm gear is installed, one end of described main shaft is movably arranged in the main eccentric bushing, the other end is movably arranged in the supporting eccentric bushing that matches with main eccentric bushing, and main eccentric bushing and supporting eccentric bushing all are arranged on the transmission case.
The structure of described main eccentric bushing comprises: eccentric sleeve body, the outer wall of sleeve body is provided with the tightening groove of at least one ring-type, the inwall of sleeve body is respectively arranged with a bearing position in the port of both sides, the outer wall of sleeve body one end is provided with the eccentric adjustment hole of several circumferential arrangement.
The beneficial effects of the utility model are: the utility model changes wheelbase between main shaft and the worm screw by rotating main eccentric bushing and supporting eccentric bushing accordingly, to remedy the drive gap that worm and gear processing and assembly error produce, and to run in advance and or normal the use in the wearing and tearing that cause carry out the gap compensation, to increase the area of contact of worm and gear, thereby can improve the load ability to bear and the transmission accuracy of worm gear, prolong the working life of worm and gear greatly.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, worm gearing described in the utility model, comprise: transmission case 1, the main shaft 3 that is provided with the worm gear 2 that cooperatively interacts and worm screw 4 in the transmission case 1 and worm gear 2 is installed, one end of main shaft 3 is movably arranged in the main eccentric bushing 5 by bearing, the other end of main shaft 3 is movably arranged on by bearing in the supporting eccentric bushing 6 that matches with main eccentric bushing 5, and main eccentric bushing 5 and supporting eccentric bushing 6 all are bearing on the transmission case 1; In the present embodiment, as Fig. 2, Fig. 3 and shown in Figure 4, the structure of described main eccentric bushing 5 comprises: eccentric sleeve body 51---its eccentric axis 55 is with respect to center line 56 off-centre, the outer wall of sleeve body 51 is provided with the tightening groove 52 of twice ring-type, the inwall of sleeve body 51 is respectively arranged with a bearing position 53 in the port of both sides, the outer wall of sleeve body 51 1 ends is provided with the eccentric adjustment hole 54 of several circumferential arrangement; Described supporting eccentric bushing 6 has the eccentric structure identical with main eccentric bushing 5, during adjustment and main eccentric bushing 5 adjust synchronously, adjust after the end, hold out against on the tightening groove 52 on sleeve body 51 outer walls of main eccentric bushing 5 with the puller bolt 7 that is located in the transmission case 1.
Adjustment process of the present utility model is: at first unclamp puller bolt 7, then, a regulating rod is inserted in the eccentric adjustment hole, and pull regulating rod, make winner's eccentric bushing 5 go to proper angle, tighten puller bolt 7 and get final product.
