Abstract

The utility model discloses a motor shaft coupling device, belonging to the technical field of motor shaft connection. The motor shaft coupling device provided by the utility model comprises a pressing cover and a shaft sleeve; a bolt is arranged in the middle of the pressing cover; a through hole I is formed in the bolt; a shaft sleeve main body comprises a stopping ring; a boss and a casing pipe are respectively manufactured on the both faces of the stopping ring; a thread hole which is adapted with the bolt is manufactured on one face of the shaft sleeve, which is provided with the lug boss; a through hole II is manufactured on one face of the shaft sleeve, which is provided with the casing pipe; and the through hole I and the through hole II are located on the same axis and are adapted with a motor shaft. The motor shaft coupling device provided by the utility model has the beneficial effects as follows: a working piece is tightly clamped by the pressing sleeve and the shaft sleeve, which are in threaded connection, so that the motor shaft coupling device is connected with the motor shaft under the condition of not damaging the working piece or not drilling a hole on the working piece; and compared with the manners of welding, gluing or flange connection and the like, the motor shaft coupling device has the advantages of simple structure, convenience in mounting and dismounting, long effect and the like.

Description

The motor hitch bar

Technical field

The utility model relates to a kind of motor shaft jockey, belongs to motor shaft interconnection technique field.

Background technology

Need connecting motor shaft on the workpiece such as flabellum, disk and rotate with motor, in general, is in the hole of parts intermediate fabrication such as flabellum, disk with the motor shaft coupling, follows motor shaft directly to connect through modes such as screw, draw-in grooves then.Sometimes, the interior ring or the diameter of bore at workpiece middle part are big more a lot of or not adaptive than motor shaft, to this structure; Prior art generally is to connect with motor shaft through on interior ring limit, opening several screw holes, be connected with ring flange through bolt or screw, having in the middle part of the ring flange with the hole of motor shaft coupling; But, do not having the perforate condition as filter screen disk etc. is this, and other can not destroy under the occasion of workpiece; This mode just is not suitable for usefulness, therefore needs a kind of new connecting mode.

Summary of the invention

In order to overcome the weak point of above-mentioned prior art, the utility model provides a kind of motor hitch bar, can be implemented in not destroy under the occasion that does not have the perforate condition on workpiece or the workpiece to connect motor shaft.

The utility model is realized through following technical scheme: a kind of motor hitch bar, and it comprises gland and axle sleeve, there is double-screw bolt the centre of described gland; The through hole I is arranged in the double-screw bolt; Described axle sleeve body comprises back-up ring, and the two sides of back-up ring is manufactured with boss and sleeve pipe respectively, has from axle sleeve in the one side of boss to be manufactured with the screwed hole suitable with double-screw bolt; Have from axle sleeve in the one side of sleeve pipe to be manufactured with the through hole II, described through hole I and through hole II are on same axis and suitable with motor shaft.

The outer rim of described boss has several keys.

Some floors are arranged between described sleeve pipe and the back-up ring.

The interior ring of the shape of described boss, size and workpiece is suitable.

The beneficial effect of the utility model is: gland and axle sleeve through being threaded are tightly clamped workpiece such as filter screen disk, are not destroying under the occasion that does not have the perforate condition on workpiece or the workpiece, and realization is connected with motor shaft; Compared with modes such as welding, splicing or flange connections, have advantages such as simple in structure, easy accessibility, effectiveness be permanent.

Among the figure, 1, gland, 11, double-screw bolt, 12, the through hole I, 2, axle sleeve, 21, boss, 22, back-up ring, 23, sleeve pipe, 24, screwed hole, 25, the through hole II, 26, floor, 27, key.

Embodiment

As shown in the drawings a kind of it comprise gland 1 and axle sleeve 2; There is double-screw bolt 11 centre of described gland 1, and through hole I 12 is arranged in the double-screw bolt 11, and described axle sleeve 2 bodies comprise back-up ring 22; The two sides of back-up ring 22 is manufactured with boss 21 and sleeve pipe 23 respectively; Have from axle sleeve 2 to be manufactured with the screwed hole 24 suitable with double-screw bolt 11 in the one side of boss 21, have from axle sleeve 2 in the one side of sleeve pipe 23 to be manufactured with through hole II 25, described through hole I 12 and through hole II 25 are on same axis and suitable with motor shaft.

In order to make workpiece more effectively with axle sleeve 2 interlocks, can in workpiece, encircle the inboard and drive several keyways, the outer rim at axle sleeve 2 boss 21 has several suitable keys 27 simultaneously.

Some floors 26 are arranged between described sleeve pipe 23 and the back-up ring 22, both can improve intensity, screw during convenient again the installation.

The interior ring of the shape of described boss 21, size and workpiece is suitable.

During assembling, the double-screw bolt on the gland passes the interior ring of workpiece, screw in the axle sleeve 2, tightly piece-holder in the centre, motor shaft can pass in through hole I 12 and through hole II 25, whole device is realized and being connected of motor shaft through modes such as nut or pin keies.
