Abstract
The utility model discloses a push -down motor bearing, including bearing inner race and bearing inner race, be equipped with the steel ball between bearing inner race and the bearing inner race, the left and right sides of steel ball is equipped with the holder, the last lower extreme of steel ball is equipped with the slipmat, bearing inner race's positive and negative both sides are equipped with the ring packing groove, be equipped with the shield on the seal groove, the last oil duct that is equipped with of bearing inner race, the oil duct with the steel ball communicates with each other, the present invention has the characteristics of simple structure, and lower cost, high safety, and sealing performance good, the rigidity will be strong, the withstand load ability is stronger, resistant fatigue capability is stronger, long service life, etc, through close check bearing inner race, bearing inner race, end -play scope between the steel ball, can increase the loaded area of rolling element, make the bearing can bear great load, end -play less relatively enables the installation back increases the rigidity that supports, reduce vibration and noise, prevent because the slip for interior outer lane of steel ball that inertial moment caused.
Description
Technical field
The utility model relates to power tool accessory field, particularly a kind of push rod motor bearings.
Background technique
Bearing (Bearing) is a kind of important spare part in contemporary machinery.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two.Wherein rolling bearing standardization, seriation, but its radial dimension, vibration & noise is comparatively large compared with sliding bearing, and price is also higher.Rolling bearing is generally made up of outer ring, inner ring, rolling element and retainer four part, is made up of strictly speaking outer ring, inner ring, rolling element, retainer, sealing, the large part of lubricant oil six.Mainly possess outer ring, inner ring, rolling element and just surely can mean rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and the large class of roller bearing two.
And well-known, the rotatingshaft of most of motor and bearing formation are dynamically connected, and are supported and retrain rotation or the swing of rotatingshaft by bearing.Wherein, push rod motor is in line by the convert rotational motion of motor and repeatedly moves, and push rod is subject to the translation power of all directions in straight reciprocating motion, and push rod motor transmits the load of rotatingshaft by bearing.The bearing of push rod motor, meet rotatingshaft translation, rotation, vibration, and translation, rotation, vibration time continuity and alternation, therefore, the bearing of push-rod electric machine receives the effect of power of all size, all directions, has very high requirement to the rigidity of bearing, withstand load ability, fatigue resistance, working life.
Model utility content
The purpose of this utility model is to provide a kind of rigidity by strong, that withstand load ability is comparatively strong, fatigue resistance is comparatively strong, working life is longer push rod motor bearings.
The technical solution adopted in the utility model is:
A kind of push rod motor bearings, comprise bearing outer ring and bearing inner race, its innovative point is: be provided with steel ball between described bearing outer ring and bearing inner race, the left and right sides of described steel ball is provided with retainer, the upper and lower end of described steel ball is provided with bath mat, and the positive and negative both sides of described bearing outer ring are provided with annular seal groove, and described seal groove is provided with dust cover, described bearing inner race is provided with oil duct, and described oil duct communicates with described steel ball.
Further, described dust cover and described seal groove are inserted connection, and described dust cover is arcuate structure, and radian is outside.
Further, the radial internal clearance between described bearing outer ring, bearing inner race, steel ball is 0.002 ~ 0.005mm.
The beneficial effects of the utility model are as follows:
The utility model has that structure is simple, cost is lower, use safety, good airproof performance, rigidity will strong, the advantages such as withstand load ability is comparatively strong, fatigue resistance is comparatively strong, working life is longer, by the radial internal clearance scope between strict Control Shaft bearing outer-ring, bearing inner race, steel ball, the loaded area of rolling element can be increased, bearing is enable to bear larger load, relatively little radial internal clearance can make installation increase the rigidity of support afterwards, reduce vibration & noise, prevent the steel ball caused by moment of inertia relative to the slip of Internal and external cycle.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 is the utility model structural representation.
Embodiment
A kind of push rod motor bearings as shown in Figure 1, comprise bearing outer ring 1 and bearing inner race 2, steel ball 3 is provided with between described bearing outer ring 1 and bearing inner race 2, the left and right sides of described steel ball 3 is provided with retainer 4, the upper and lower end of described steel ball 3 is provided with bath mat 5, and the positive and negative both sides of described bearing outer ring 1 are provided with annular seal groove 6, and described seal groove 6 is provided with dust cover 7, described bearing inner race 2 is provided with oil duct 8, and described oil duct 8 communicates with described steel ball 3.
Working principle of the present utility model is:
In use, by the radial internal clearance scope between strict Control Shaft bearing outer-ring 1, bearing inner race 2, steel ball 3, the loaded area of rolling element can be increased, bearing is enable to bear larger load, relatively little radial internal clearance can make installation increase the rigidity of support afterwards, reduce vibration & noise, prevent the steel ball caused by moment of inertia relative to the slip of Internal and external cycle.
The above is preferred implementation of the present utility model, can not limit the interest field of the utility model with this.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified or equivalent replacement, do not depart from protection domain of the present utility model.
Claims (3)
