Abstract
The utility model belongs to the construction applications of elevator, specifically a kind of rotation-prevention backgear of elevator, comprise backgear assembly, backgear axle, driver plate, connecting element, backgear assembly is installed on backgear axle, connecting element is successively through driver plate and backgear axle, and driver plate and backgear axle are fixed, the end face that backgear axle contacts with driver plate has backgear axle and embeds step, driver plate has and to embed the counterbore or through hole that step adapts with backgear axle, be positioned at driver plate and reinforcement backing plate for fixing backgear axle is set relative to the opposite side of backgear axle.The beneficial effects of the utility model are: eliminate the eccentric bushing be welded on driver plate, fixed cover, make driver plate stressed evenly, improve stability during running, and simplified structure, reduce manufacturing procedure, reduce costs.
Description
Technical field
The utility model belongs to the construction applications of elevator, specifically a kind of rotation-prevention backgear of elevator.
Background technology
In existing design, general employing eccentric bushing coordinates with fixed cover, fixed cover is welded on the version on driver plate, because fixed cover is important stressed member, during welding, weld seam is comparatively large, and driver plate can be caused to be out of shape, when making the driving gear wheel and rack engagement be arranged on driver plate, tooth trace is not parallel, causes cage to run shake.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of rotation-prevention backgear of elevator, make driver plate stressed evenly, improve running time stability.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of rotation-prevention backgear of elevator, comprise backgear assembly, backgear axle, driver plate, connecting element, backgear assembly is installed on backgear axle, connecting element is successively through driver plate and backgear axle, and driver plate and backgear axle are fixed, the end face that backgear axle contacts with driver plate has backgear axle and embeds step, driver plate has and to embed the counterbore or through hole that step adapts with backgear axle, be positioned at driver plate and reinforcement backing plate for fixing backgear axle is set relative to the opposite side of backgear axle.
And described connecting element is bolt or bearing pin.
The beneficial effects of the utility model are: eliminate the eccentric bushing be welded on driver plate, fixed cover, make driver plate stressed evenly, improve stability during running, and simplified structure, reduce manufacturing procedure, reduce costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, backgear assembly, 2, backgear axle, 3, driver plate, 4, connecting element, 5, backgear axle embeds step, 6, counterbore or through hole, 7, backing plate is strengthened.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment provides a kind of rotation-prevention backgear of elevator, as shown in Figure 1, comprise backgear assembly 1, backgear axle 2, driver plate 3, connecting element 4, backgear assembly 1 is installed on backgear axle 2, connecting element 4 is successively through driver plate 3 and backgear axle 2, and driver plate 3 and backgear axle 2 are fixed, the end face that backgear axle 2 contacts with driver plate 3 has backgear axle and embeds step 5, driver plate 3 has and to embed the counterbore or through hole 6 that step 5 adapts with backgear axle.Be positioned at the opposite side setting of driver plate 3 relative to backgear axle 2 for the reinforcement backing plate 7 of fixing backgear axle 2, strengthen backing plate 7 and driver plate 3 can be allowed to increase area of thrust surface in this local, reduce local stress.Described connecting element 4 can be bolt or bearing pin.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement or distortion, these improve or distortion also should be considered as protection domain of the present utility model.
