Abstract
The invention discloses a kind of single-ended mechanical seal structure of motor, mechanical seal chamber including being arranged on motor one end, grease chamber lid is covered with the one end in the mechanical seal chamber, offered in the middle part of the grease chamber lid and wear axis hole, mechanical sealing member is provided with axis hole in described wearing, is provided with the output shaft of the motor for mechanical sealing member to be crimped on the crimp worn on axis hole.The present invention can be accurately positioned the position of mechanical seal, can effectively avoid mechanical sealing member too loose or too tight produced shortcoming.
Description
Technical field
The present invention relates to technical field of motors, a kind of single-ended mechanical seal structure of motor is related specifically to.
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 can by the heat of motor interior transfer out rapidly come, cooling effect
Preferably, the temperature rise of motor is significantly declined, thus increased the overload capacity of motor.
In the prior art in order to prevent the machinery oil being injected in mechanical seal chamber from spilling, set at axis hole in being worn for grease chamber lid
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 be accurately positioned the position of 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 for sealing chamber brings larger problem.
But in view of the shortcomings of the prior art, developer be necessary to develop a kind of reasonable in design, simple structure, 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
End mechanical seal structure.
The content of the invention
To solve the problems, such as prior art, the object of the invention provides a kind of reasonable in design, simple structure, Neng Goujing
It is determined that the position of position mechanical sealing member, can effectively avoid mechanical sealing member too loose or the motor of too tight produced shortcoming is used
Single-ended mechanical seal structure.
To solve above technical problem, what the present invention 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 wearing
Tool seal, it is characterised in that be provided with the output shaft of the motor and wear on axis hole for mechanical sealing member to be crimped on
Crimp.
In a preferred embodiment of the invention, the crimp includes trim ring and snap ring, on the output shaft of motor
Annular groove is offered, the snap ring is connected in annular groove, the trim ring is set on the output shaft of motor and close positioned at machinery
Between sealing and snap ring.
Compared with prior art, the present invention to be provided with the output shaft of motor and wear axis hole for mechanical sealing member to be crimped on
On 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 between mechanical sealing member and snap ring, is adopted the structure and is not only able to essence
It is determined that the position of position mechanical sealing member, and also can effectively avoid mechanical sealing member too loose or too tight produced shortcoming.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is structural representation of the invention.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.

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。
Mechanical sealing member 300 is provided with axis hole 210 wearing, mechanical sealing member 300 be set on the output shaft 500 of motor and
It is crimped on and wears on axis hole 210, is provided with the output shaft 500 of motor and wear axis hole 210 for mechanical sealing member 300 to be crimped on
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 also can effectively avoid machinery close
Sealing is too loose or too tight produced shortcoming.
The present invention is provided with the output shaft of motor for mechanical sealing member to be crimped on the pressure worn on axis hole in sum
Fitting, crimp includes trim ring and snap ring, and annular groove is offered on the output shaft of motor, and snap ring is connected in annular groove, pressure
Snare is located on the output shaft of motor and between mechanical sealing member and snap ring, is adopted the structure and is not only able to be accurately positioned
The position of mechanical sealing member, and also can effectively avoid mechanical sealing member too loose or too tight produced shortcoming.
General principle of the invention, principal character and advantages of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited to the above embodiments, simply explanation described in above-described embodiment and specification this
