Description
Technical field
The invention belongs to power tool accessory field, and in particular to a kind of push-down motor bearings.
Background technology
Bearing（Bearing）It is a kind of important spare part in contemporary plant equipment.Its major function is support machinery rotation
Swivel, reduces the coefficient of friction in its motion process, and ensure its rotating accuracy.By the difference of motor element frictional property, axle
Rolling bearing and the major class of sliding bearing two can be divided into by holding.Wherein rolling bearing is normalized, seriation, but with sliding bearing phase
More larger than its radial dimension, vibration and noise, price is also higher.Rolling bearing is typically by outer ring, inner ring, rolling element and holding
The part of frame four forms, and is strictly speaking made up of outer ring, inner ring, rolling element, retainer, sealing, six big part of lubricating oil.Mainly
Possess outer ring, inner ring, rolling element can determine mean rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and rolling
The sub- major class of bearing two.
And it is well known that the dynamic connection of rotary shaft and bearing composition of most of motors, supports and constrains rotation by bearing
The rotation or swing of axle.Wherein, push-down motor is in line by the convert rotational motion of motor and moved repeatedly, and push rod exists
The load of rotary shaft is transmitted by bearing by the translation power of all directions, push-down motor in straight reciprocating motion.Push-down
The bearing of motor, rotary shaft translation, rotation, vibration, and continuity and alternation when translation, rotation, vibration are met, because
This, the bearing of push-rod electric machine receive all size, all directions power effect, it is rigidity, load resistance ability to bearing, resistance to
Fatigue capability, service life have very high requirement.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to now provide, one kind is simple in construction, sealing effectiveness is good, uses
The push-down motor bearings of long lifespan.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of push-down motor bearings, including bearing
Outer ring and bearing inner race, its innovative point are：Steel ball, a left side for the steel ball are installed between the bearing outer ring and bearing inner race
Right both sides are provided with retainer, and the upper and lower side of the steel ball is provided with slipmat, and the positive and negative both sides of the bearing outer ring are provided with
Annular seal groove, dust cap is installed on the seal groove, the inner end of the dust cap is installed with sealing blend stop, described
Oil duct is installed, the oil duct is communicated with the steel ball, and the outer surface of the bearing outer ring is also installed with bearing inner race
One wearing layer, the thickness of the wearing layer is 1-3mm.
Further, the dust cap and the seal groove are inserted connection, and the dust cap is arcuate structure, and arc
Spend it is outward-dipping, the arc angle be 45-80 °.
Further, the end-play between the bearing outer ring, bearing inner race, steel ball is 0.002-0.004mm.
Beneficial effects of the present invention are as follows：
（1）The present invention have simple in construction, cost is relatively low, safe to use, good airproof performance, rigidity will strong, load resistance ability it is relatively strong,
The advantages that fatigue resistance is relatively strong, service life is longer, by strictly controlling the footpath between bearing outer ring, bearing inner race, steel ball
To clearance scope, the loaded area of rolling element can be increased, bearing is born larger load, relatively small end-play
The rigidity for increasing support after installation can be made, vibration and noise is reduced, prevent the steel ball caused by moment of inertia relative to interior
The slip of outer ring.
（2）The present invention can effectively strengthen the close of dust cap by being installed with a sealing blend stop inside dust cap
Effect is sealed, and by adding wearing layer in bearing outer ring, can effectively extend the service life of bearing.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.

Dingan County is provided with oil duct 8, oil duct 8 communicates with steel ball 3, the outer surface of bearing outer ring 1 equipped with blend stop 71 is sealed on bearing inner race 2
A wearing layer 11 is also installed with, the thickness of wearing layer 11 is 1-3mm.
Dust cap 7 and seal groove 6 are inserted connection, and dust cap 7 is arcuate structure, and radian is outward-dipping, and arc angle is
45-80°.The present invention can effectively strengthen the close of dust cap 7 by being installed with a sealing blend stop 71 inside dust cap 7
Effect is sealed, and by adding wearing layer in bearing outer ring 1, can effectively extend the service life of bearing.
End-play between bearing outer ring 1, bearing inner race 2, steel ball 3 is 0.002-0.004mm.
The present invention have simple in construction, cost is relatively low, safe to use, good airproof performance, rigidity will strong, load resistance ability compared with
By force, the advantages that fatigue resistance is relatively strong, service life is longer, by strictly control bearing outer ring 1, bearing inner race 2, steel ball 3 it
Between end-play scope, the loaded area of rolling element can be increased, bearing is born larger load, relatively small footpath
Increase the rigidity of support after making installation to clearance, reduce vibration and noise, prevent the phase of steel ball 3 caused by moment of inertia
Slip for Internal and external cycle.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as
The technical scheme that can be realized on the basis of above-described embodiment without creative work, it is regarded as falling into patent of the present invention
Rights protection scope in.
