Description

A kind of single-ended mechanical seal structure of motor

Technical field

The utility model is related to technical field of motors, is related specifically to a kind of single-ended mechanical seal structure of motor.

Background technology

There are motor cavity and mechanical seal chamber in motor internal, the inside is full of machinery oil, make mechanical seal and bearing in work In have good lubricating condition, while motor cavity fluid the heat of motor interior can rapidly be transferred out come, cooling effect Preferably, the temperature rise of motor is significantly declined, thus add the overload capacity of motor.

In the prior art in order to prevent the machinery oil for being injected at mechanical seal intracavitary from spilling, set in wearing for grease chamber lid at axis hole There is mechanical sealing member, and the mechanical sealing member of prior art is mostly to be bolted on to wear at axis hole, and use Bolt is difficult to the position for being accurately positioned mechanical seal, if mechanical sealing member is too loose easily to make machinery oil from mechanical annular seal space Spill, if mechanical sealing member tightly easily brings it about deformation very much, influence its sealing property and service life, so that close to machinery The seal operation of envelope chamber brings larger problem.

But in view of the shortcomings of the prior art, developer be necessary to develop it is a kind of it is reasonable in design, simple in construction, can be accurate The position of positioning mechanical seal, can effectively avoid mechanical sealing member too loose or the motor of too tight produced shortcoming is single Hold mechanical seal structure.

Utility model content

To solve the problem of prior art is present, the utility model purpose provides a kind of reasonable in design, simple in construction, energy Enough be accurately positioned the position of mechanical seal, can effectively avoid mechanical sealing member too loose or too tight produced shortcoming electricity The single-ended mechanical seal structure of machine.

To solve above technical problem, what the utility model was realized using following technical scheme：

A kind of single-ended mechanical seal structure of motor, including the mechanical seal chamber of motor one end is arranged on, in the machinery One end of annular seal space is covered with grease chamber lid, is offered in the middle part of the grease chamber lid and wears axis hole, and machine is provided with axis hole in described wear Tool seal, it is characterised in that being provided with the output shaft of the motor is used to mechanical sealing member being crimped on to wear on axis hole Crimp.

In a preferred embodiment of the present utility model, the crimp includes trim ring and snap ring, in the output of motor Annular groove is offered on axle, the snap ring is connected in annular groove, the trim ring is set on the output shaft of motor and positioned at machine Between tool seal and snap ring.

Compared with prior art, the utility model is provided with the output shaft of motor is used to mechanical sealing member being crimped on to wear Crimp on axis hole, crimp includes trim ring and snap ring, annular groove is offered on the output shaft of motor, snap ring is connected to card In annular groove, trim ring is set on the output shaft of motor and positioned between mechanical sealing member and snap ring, not only can adopted the structure Enough it is accurately positioned the position of mechanical seal, and can also effectively avoids mechanical sealing member too loose or too tight produced lack Point.

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is structural representation of the present utility model.

Embodiment

In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

Shown in reference picture 1, the single-ended mechanical seal structure of a kind of motor provided in figure, including it is arranged on motor one end Mechanical seal chamber 100.

Grease chamber lid 200 is provided with the right end cap of mechanical seal chamber 100, grease chamber lid 200 is fixedly mounted on machine by bolt 600 On the right-hand member of tool annular seal space 100, offered at the middle part of grease chamber lid 200 and wear axis hole for the output shaft 500 through motor 210。

Wearing at axis hole 210 be provided with mechanical sealing member 300, mechanical sealing member 300 be set on the output shaft 500 of motor and It is crimped on and wears on axis hole 210, being provided with the output shaft 500 of motor is used to mechanical sealing member 300 being crimped on to wear axis hole 210 Crimp.

Crimp includes trim ring 410 and snap ring 420, and annular groove 510, snap ring 420 are offered on the output shaft 500 of motor It is connected in annular groove 510, trim ring 410 is set on the output shaft 500 of motor and positioned at mechanical sealing member 300 and snap ring 420 Between, the position for being not only able to be accurately positioned mechanical seal is adopted the structure, and can also effectively avoid machinery close Sealing is too loose or too tight produced shortcoming.

The utility model is provided with the output shaft of motor in summary is used to mechanical sealing member being crimped on to wear axis hole Crimp, crimp include trim ring and snap ring, annular groove is offered on the output shaft of motor, snap ring is connected to annular groove Interior, trim ring is set on the output shaft of motor and positioned between mechanical sealing member and snap ring, adopts the structure and be not only able to essence It is determined that the position of position mechanical sealing member, and can also effectively avoid mechanical sealing member too loose or too tight produced shortcoming.

General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, the utility model can also on the premise of the utility model spirit and scope are not departed from There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.The utility model will Protection domain is asked to be defined by appended claims and its equivalent.
