Abstract
The utility model discloses a rotation prevention gasket used for a motor shaft. The rotation prevention gasket comprises a gasket body, and the gasket body is provided with a central axle hole through which the motor shaft passes. A side of the gasket body is provided with a rotation prevention boss, and the other side of the gasket body is provided with a positioning clamping foot. The rotation prevention boss and the positioning clamping foot are integrally disposed on the gasket body. Through the above method, the rotation prevention gasket used for a motor shaft is simple in connection and convenient in installation, and radial forces the motor shaft bears are increased, excessive friction is reduced, relative rotation of the motor shaft is reduced. The rotation prevention gasket has a good fixing function on the motor shaft, shaking phenomenon of the motor shaft in an operation process is reduced, and service life of the motor shaft is prolonged.

In service at motor, motor shaft can rotate together with the accessory being arranged on axle, and its frictional force increases, and when motor shaft running, rocks increasing, has affected useful life.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of motor shaft Anti-rotating grommet, connect simple, easy for installation, increase the radial load that motor shaft bears, reduce unnecessary friction, reduced relatively rotating of motor shaft, motor shaft has been played to good fixation, reduce the shaking phenomenon of motor shaft operation process, extended the useful life of motor shaft.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of motor shaft Anti-rotating grommet is provided, comprise: packing ring body, on packing ring body, be provided with the central shaft hole passing for motor shaft, a side at packing ring body is formed with anti-rotation boss, be formed with location card base at the opposite side of packing ring body, card base is one-body molded is arranged on packing ring body for described anti-rotation boss and location.
In preferred embodiment of the utility model, described central shaft hole is flat position through hole, and motor shaft is connected with packing ring body by flat position through hole.
In preferred embodiment of the utility model, on the card base of described location, be formed with groove, the cross section of described groove is circular arc setting.
In preferred embodiment of the utility model, described packing ring body adopts 45# steel to make.
In preferred embodiment of the utility model, wax machine is one-body molded to be arranged on packing ring body by penetrating for described anti-rotation boss and location card base.
The beneficial effects of the utility model are: the utility model motor shaft connects simple with Anti-rotating grommet, easy for installation, increase the radial load that motor shaft bears, reduce unnecessary friction, reduce relatively rotating of motor shaft, motor shaft is played to good fixation, reduced the shaking phenomenon of motor shaft operation process, extended the useful life of motor shaft.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of a preferred embodiment of motor shaft of the present utility model Anti-rotating grommet;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, packing ring body, 2, central shaft hole, 3, anti-rotation boss, 4, location card base, 5, groove.
Embodiment
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 3, the utility model embodiment comprises:
A kind of motor shaft Anti-rotating grommet, comprising: packing ring body 1, is provided with the central shaft hole 2 passing for motor shaft on packing ring body 1.
Described central shaft hole 2 is flat position through hole, and motor shaft is connected with packing ring body 1 by flat position through hole, and it connects simple, easy for installation.
A side at packing ring body 1 is formed with anti-rotation boss 3, has increased the radial load that motor shaft bears, and has reduced unnecessary friction, has reduced relatively rotating of motor shaft, has extended the useful life of motor shaft.
Be formed with location card base 4 at the opposite side of packing ring body 1, on described location card base 4, be formed with groove 5, the cross section of groove 5 is circular arc setting, and groove 5 is connected on motor shaft, motor shaft is played to good fixation, reduced the shaking phenomenon of motor shaft operation process.
Described packing ring body 1 adopts 45# steel to make, and has improved fatigue performance and the anti-wear performance of Anti-rotating grommet, has extended the useful life of motor shaft.
Wax machine is one-body molded to be arranged on packing ring body 1 by penetrating for described anti-rotation boss 3 and location card base 4, simple to operate, energy-saving safe, and environment-friendly high-efficiency, automaticity is high, and Anti-rotating grommet surface smoothness also improves.
Before penetrating wax, first make cere, be welded with multiple Anti-rotating grommet modules on cere, adjacent Anti-rotating grommet modular spacing is 8mm ~ 10mm, and when welding, wax-pattern layback, is convenient to dewaxing so more.After packing ring body forms, overlap is repaiied totally, and push rod prints equating.
The utility model motor shaft with the beneficial effect of Anti-rotating grommet is:
Connect simply, easy for installation, increase the radial load that motor shaft bears, reduce unnecessary friction, reduced relatively rotating of motor shaft, motor shaft has been played to good fixation, reduce the shaking phenomenon of motor shaft operation process, extended the useful life of motor shaft.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
