Description
Technical field
The present invention relates to a kind of motor, particularly relate to a kind of detachable motor.
Background technology
There is following problem in existing motor: one, bearing outer ring and electric motor end cap are tight fit, if bearing damage or kill can have influence on the precision of electric motor end cap, even if changed after bearing, concentricity reduces greatly; Two, after bearing damage, pull out bearing and whole rotor need be exited, be subject to the restriction of site environment, need outer power lifting, greatly increase maintenance dynamics and cost; Three, in use there is lubricating grease easy to leak, easily throw away, easily in outer bearing cover, pile up and easily cause extraneous foreign matter to enter the problem of bearing in existing bearing lubrication structure; If four, motor excess Temperature, internal lubrication oil runs off very fast, and conventional motors is refueled and only from fuel filler neck, refueled.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of detachable motor, and it changes bearing under the prerequisite of not dismantling motor front end cover, back end cover for motor, reduces maintenance dynamics and cost.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of detachable motor, it is characterized in that, it comprises motor shaft, motor front end cover, back end cover for motor, clutch shaft bearing gland, clutch shaft bearing body, the second bearing gland, the second bearing body, clutch shaft bearing gland, the second bearing gland is all enclosed within on motor shaft, clutch shaft bearing gland coordinates with clutch shaft bearing body space, the second bearing gland and the second bearing body matched in clearance, motor front end cover is positioned at the outside of clutch shaft bearing body, back end cover for motor is positioned at the outside of the second bearing body, in clutch shaft bearing body, be provided with clutch shaft bearing, in the second bearing body, be provided with the second bearing.
Preferably, described clutch shaft bearing body is provided with the first tank filler sleeve, and the second bearing body is provided with the second tank filler sleeve.
Preferably, described motor rear end covers cover a fan guard.
Preferably, the inner side end of described clutch shaft bearing gland is provided with the first labyrinth seal ring, and the inner side end of the second bearing gland is provided with the second labyrinth seal ring.
Preferably, described clutch shaft bearing body and motor front end cover tight fit.
Preferably, described the second bearing body and back end cover for motor tight fit.
Preferably, on described clutch shaft bearing body and the second bearing body, all there is top wire hole.
Positive progressive effect of the present invention is: one,, because bearing outside is independent bearing body, bearing can be taken out of, therefore need not dismantle the parts such as electric machine rotor when removing bearing body.The present invention changes bearing under the prerequisite of not dismantling motor front end cover, back end cover for motor, reduces maintenance dynamics and cost.Two, bearing has independent bearing body structure, bearing damage and exit and also can not have influence on other parts of motor.Three, change bearing and only bearing body need be ejected, from bearing, take out, without mobile motor rotor, time saving and energy saving.Four, the inner side end of the inner side end of clutch shaft bearing gland, the second bearing gland is all provided with labyrinth seal ring one, efficiently solve existing bearing lubrication structure in use lubricating grease easy to leak, easily throw away, easily in outer bearing cover, pile up and easily cause extraneous foreign matter to enter the problem of bearing.Five, clutch shaft bearing body, the second bearing body are all provided with independent tank filler sleeve, if need, fully refuel, also can be by clutch shaft bearing body, the whole taking-up of the second bearing body, convenient oiling.Six, bearing and motor front end cover, back end cover for motor, all for independently, do not need while changing consumable accessory to borrow outer power just dismountable, convenient and swift.
Accompanying drawing explanation
Fig. 1 is the structural representation of detachable motor of the present invention.
Fig. 2 is the structural representation of middle (center) bearing gland of the present invention, bearing body, tank filler sleeve.
