Abstract

The utility model discloses a clamping hoop used for motor connection, which comprises an Omega-shaped clamping hoop body, a bolt inserted into the connecting lugs at the two ends of the opening of the clamping hoop body and a nut arranged on the bolt, wherein the inner surface of the clamping hoop body (5) is a trapezoid-shaped annular groove. The utility model not only the defects in the prior art, such as strict requirement for accuracy, trouble fabrication and difficulty in assembly and disassembly, but also allows relative rotation between a motor and a reduction gearbox. Accordingly, the included angle (alpha) between a brake handle and the central plane of the reduction gearbox can be adjusted freely in circumference, so as to improve interchangeability and versatility between the motor and the reduction gearbox. The clamping hoop is an ideal structural part suitable for connecting a motor and a reduction gearbox.

Description

Motor connects uses clip

Technical field

The utility model relates to a kind of clip, relates in particular to a kind of clip that is used to connect motor and reduction box.

Background technology

As everyone knows, be to realize being connected mostly between motor and the reduction box by ring flange and bolt.Though this traditional connected mode is more firm, must on the front end housing of motor, processes one group of bolt via hole, also will process one group of screw accordingly at the faying face of reduction box and motor front end housing; Not only processing capacity is bigger, and position accuracy demand is higher, and dismounting simultaneously is also cumbersome.In addition, owing to be located between brake handle and the reduction box median plane on the wheelchair motor angle α requirement is arranged, and motor is more fixing with respect to the position of reduction box in assembling process, so the adjustment of angle α is relatively more difficult.

Summary of the invention

At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of motor connection clip simple in structure, easy to process, easy-to-disassemble and assemble.

To achieve these goals, the utility model is by the following technical solutions: it comprises the clip body that is the Ω shape, intert bolt on this clip body openings two ends engaging lug, be located at the nut on this bolt; The inner surface structure of clip body is the annular groove of trapezoidal shape.

Between two engaging lugs, be provided with the spacer that is enclosed within on the bolt.

Compared with the prior art, the utility model is owing to adopted technique scheme, therefore only need the back side of motor and reduction box faying face is processed into and the suitable inclined-plane of the annular groove of clip body internal surface, can utilize clip that motor and reduction box conveniently are connected as a single entity; Many defectives such as traditional connected mode position accuracy demand height, processing trouble, dismounting difficulty have not only been overcome, and owing to can relatively rotate between motor and the reduction box, therefore the angle α between brake handle and the reduction box median plane can regulate arbitrarily on circumference as required, has improved the exchange versatility between motor and the reduction box.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

In Fig. 1～6, clip body 5 is Ω shape structure, and the inner surface of this clip body is the circular groove structure of trapezoidal shape; Both ends open place at clip body 5 is provided with engaging lug 2 respectively, and each engaging lug 2 is provided with through hole.It is protruding that bolt 4 passes the described through hole of each engaging lug 2, and turning the nut 1 that is located on the bolt 4 can tighten up clip body 5 openings at two ends or unclamp.For fear of because of the nut 1 overtighten engaging lug 2 that causes is out of shape, be provided with the spacer 3 that is enclosed within on the bolt 4 between two lugs 2.

From Fig. 3, Fig. 5 and Fig. 6 as can be seen, the front of motor 6 front end housings is that planar structure, the back side are and the suitable ramp structure of clip body 5 inner surface annular grooves, and reduction box 7 is that planar structure, the back side are and the suitable ramp structure of clip body 5 inner surface annular grooves with the faying face of motor 6 front end housings.During use, clip body 5 is enclosed within the junction of motor 6 and reduction box 7, fastening nut 1 can be by clip body 5 with motor 6 and reduction box 7 fastenings.

As can be seen from Figure 7, adopt ring flange to fixedly connected between motor 6 and the reduction box 7, so position accuracy demand is higher with four bolts 1; And be located at angle α between the median plane of brake handle 8 on the motor 6 and reduction box 7 also because the restriction of four bolts 1 adjusts the comparison difficulty.

Claims

1. a motor connects and uses clip, comprise the clip body that is the Ω shape, intert bolt on this clip body openings two ends engaging lug, be located at the nut on this bolt; It is characterized in that: the inner surface structure of clip body (5) is the annular groove of trapezoidal shape.

2. motor according to claim 1 connects uses clip, it is characterized in that: be provided with the spacer (3) that is enclosed within on the bolt (4) between two engaging lugs (2).
