Abstract
The utility model provides a sealing structure of excavator motor belongs to mechanical technical field. The problem that the sealing effect of an existing excavator motor is poor is solved. The motor in the sealing structure of the excavator motor comprises a shell, a stator, a rotor, a coil winding and a motor shaft are installed in the shell, the front end of the shell is fixedly connected with a front end cover, the inner end face of the rear end of the front end cover is fixedly connected with a front outer cover, and a shaft face oil seal is installed between the front outer cover and the motor shaft. The sealing structure of the excavator motor has the advantages of simple structure and good sealing effect.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of motor, particularly a kind of motor seal structure that is applicable in the development machine.
Background technology
The development machine motor is in long-term use; The phenomenon that the market reflection often has bearing failure, insulation resistance is low and burns motor; These all are that the motor seal weak effect causes; So that the user stops production and repairs and the replacing motor, causes enormous economic loss to the user, and this is the ubiquitous problem of this type of motor.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of development machine motor seal structure of simple in structure, good sealing effect.
The purpose of the utility model can realize through following technical proposal: a kind of development machine motor seal structure; This motor comprises casing; Stator, rotor, coil windings and motor shaft are installed in the described casing, and described casing front end is fixed with front end housing, it is characterized in that; Be fixed with preceding enclosing cover on the inner face of described front end housing rear end, between described preceding enclosing cover and the motor shaft axial plane oil sealing be installed.
Compared with prior art, this development machine motor seal structure passes through between motor shaft and preceding enclosing cover, to increase the axial plane oil sealing, motor shaft and axial plane oil sealing interference fit, and the rubber part of axial plane oil sealing and preceding enclosing cover fit together, and have reached the water proof and dust proof effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structure for amplifying sketch map at A place among Fig. 1.
Among the figure, 1, casing; 2, stator; 3, rotor; 4, coil windings; 5, motor shaft; 6, front end housing; 7, preceding enclosing cover; 8, axial plane oil sealing.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As depicted in figs. 1 and 2; Motor in this development machine motor seal structure comprises casing 1; Stator 2, rotor 3, coil windings 4 and motor shaft 5 are installed in casing 1; Be fixed with front end housing 6 at casing 1 front end, enclosing cover 7 before on the inner face of front end housing 6 rear ends, being fixed with is equipped with axial plane oil sealing 8 between preceding enclosing cover 7 and the motor shaft 5.This development machine motor seal structure passes through between motor shaft 5 and preceding enclosing cover 7, to increase axial plane oil sealing 8, motor shaft 5 and axial plane oil sealing 8 interference fit, and the rubber part of axial plane oil sealing 8 and preceding enclosing cover 7 fit together, and have reached the water proof and dust proof effect.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
