Abstract
The utility model is the adverse circumstances and the safeguard structure designed of filling the air for dust granules and dust, a kind of electric motor end cap protector being applicable to dirty environment specifically, this structure is by end cap, bearing end cover, internal bearing cover, cover plate, axial plane oil sealing, outside framework oil seal, disc, the compositions such as connecting bolt, pass through cover plate, axial plane oil sealing, outside framework oil seal and the protection of disc four road, this zigzag structural shielding can effectively prevent dust from entering bearing, ensure that bearing can safe operation, extend the useful life of motor, be specially adapted to coal, metallurgical, stone crushers etc. mechanically.
Description
Technical field
The utility model relates to field of motor manufacturing, specifically a kind of electric motor end cap protector being applicable to dirty environment.
Background technology
The motor worked under the work under bad environment that the dusts such as stone crusher, coal, metallurgy, mining machinery are more, the motor of general degree of protection, its structure processes a groove at bearing end cover place exactly, for installing sealing ring or axial plane oil sealing, actual effect is very poor, major part motor is all because bearing enters dust, causes bearing damage, then motor damage.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides one to be provided with Multiple Protective Structure, reasonable in design, easy to maintenance, the to improve durability electric motor end cap protector being applicable to dirty environment.
The utility model solves the problems of the technologies described above taked technical scheme: a kind of electric motor end cap protector being applicable to dirty environment, be provided with axle, end cap, bearing end cover, internal bearing cover, cover plate, axial plane oil sealing, outside framework oil seal, disc, connecting bolt, it is characterized in that: this device adopts four road protection, between the end cap of bearing end cover lateral, be provided with cover plate protection successively, axial plane oil sealing protects, outside framework oil seal protects, disc protects, described cover plate is fixed on bearing end cover, described axial plane oil sealing is fixed on axle, described axial plane oil sealing is provided with rubber lip, rubber lip is close on bearing end cover side, the metal-back of axial plane oil sealing and bearing end cover radial clearance are about 1mm, described outside framework oil seal is fixed on bearing end cover inner groovy, two rubber lips in described outside framework oil seal axis hole place contact with the surface pressing of axle, described disc is arranged on the outside of bearing.
The utility model, owing to taking said structure, by the protection of cover plate, axial plane oil sealing, outside framework oil seal and disc four road, prevents dust from entering bearing, ensures that bearing can safe operation, extends the useful life of motor.
Accompanying drawing explanation
Fig. 1 is the utility model end cap safeguard structure schematic diagram;
Fig. 2 is partial structurtes schematic diagram of the present utility model.
Be labeled as in figure: 1. axle; 2. cover plate; 3. axial plane oil sealing; 4. connecting bolt; 5. outside framework oil seal; 6. bearing end cover; 7. disc; 8. internal bearing cover; 9. end cap.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in the figure, the utility model relates to a kind of electric motor end cap protector being applicable to dirty environment, other motor is made up of parts such as stator, rotor, front and rear cover, front and back bearings enclosing cover, front and back bearings inner cap, bearings at both ends, accompanying drawing is depicted as front end housing safeguard structure, and rear end cap safeguard structure is identical therewith.This device is by axle, end cap, bearing end cover, internal bearing cover, cover plate, axial plane oil sealing, outside framework oil seal, disc, connecting bolt forms, cover plate is arranged on bearing end cover, as first sealing protection, outside the dust of external environment is isolated in, axial plane oil sealing is fixed on axle, axial plane oil sealing is made up of metal shell and rubber lip, the radial clearance of metal shell and bearing end cover controls at about 1mm, rubber lip is attached on the side of bearing end cover groove, high temperature resistant lubricating grease need be smeared in side, rotate with the axis, air-flow is produced when axle rotates, the dust entered by cover plate is isolated in outside bearing end cover groove.
Outside framework oil seal is fixed on bearing end cover inboard groove, does not rotate with the axis, and outside framework oil seal axis hole place is with two rubber lips, and rubber lip contacts with the surface pressing of axle, as the protection at axis hole place, prevents the dust upstream end cover cavity entered by axial plane oil sealing.
Disc is arranged on the outside of bearing, when the shaft is rotated, due to the rotation of bearing, lubricating grease on bearing can under the centrifugal action of ball and bearing rotary, lubricating grease is extruded outside disc, adding under the suitable state of lubricating grease, lubricating grease is full of between the external diameter of disc and bearing end cover, by the dust gear by three road protection outside, during time-based maintenance, add lubricating grease at the injection system of motor, the lubricating grease of pollution passes through drain oil, get rid of outside motor, extend the useful life of bearing.
Claims (1)
