Embodiment
Referring to figs. 1 through Fig. 5, the utility model low frictional torque bearing embodiment is described further.
As shown in Figures 1 to 5, a kind of low frictional torque bearing, comprise retainer 4 and roller 3, it is characterized in that: described retainer 4 is separated with roller 3 and puts, be provided with for reducing the rolling pearl 5 rubbing and keep roller 3 distance between described roller 3 and retainer 4, described rolling pearl 5 connection retainer 4 and roller 3.
Be separated with retainer 4 by roller 3, roller 3 is not contacting with retainer 4, decreases the friction between roller 3 and retainer 4; Rolling pearl 5 connection retainer 4 and roller 3, change original sliding friction into rolling friction, reduces friction, utilize rolling pearl 5 to control the spacing of roller 3, roller 3 is not offset in retainer 4, make bearing lower safer in working order, rub little, heating value is little.
Be connected by rolling pearl 5 between retainer 4 with roller 3, surface of contact is only two places, and during guarantee bearing working, generation vibration is less, reduces the noise that bearing sends.
Wherein, described retainer 4 is annular slice, retainer 4 comprises internal surface, described roller 3 is cydariform, and roller 3 comprises plane, and described plane is relative with internal surface, plane is provided with circular groove 31, described retainer 4 is provided with ball grooves 43, and described rolling pearl 5 is embedded in ball grooves 43, and the part that rolling pearl 5 exposes ball grooves 43 is conflicted with circular groove 31.
Rolling pearl 5 is embedded in ball grooves 43, make it rotation can only occur, rolling pearl 5 cannot be moved by retainer 4 relatively, and ball grooves 43 spacing is each other fixed, then the spacing between rolling pearl 5 is also fixed value, rolling pearl 5 is in circular groove 31 mobile, when roller 3 rotates, rolling pearl 5 rotates because of the effect of circular groove 31, and drives retainer 4 to rotate, the spacing of roller 3 is fixed, plays the effect that retainer 4 keeps roller 3 spacing.Retainer 4 is connected for rolling with the contact of roller 3, decreases the friction between retainer 4 and roller 3 and vibration, reduces heating value and the noise of bearing.
Wherein, described circular groove 31 and three rolling pearls 5 are conflicted, and the distance of center circle between described adjacent rolling pearl 5 is identical, and the center of circle of rolling pearl 5 is equilateral triangle arrangement.
Corresponding three the rolling pearls 5 of circular groove 31, not easily swing between retainer 4 and roller 3 and vibrate, reducing the noise between roller 3 and retainer 4.If rolling pearl 5 is 1, be then difficult to make it fix, and the friction of rolling between pearl 5 and roller 3 is sliding friction, frictional force is comparatively large, and heat yield is large; If rolling pearl 5 is 2, then easily there is double swerve in the relative retainer 4 of roller 3, and the vibration of generation is more, and rolling pearl 5 is not easily fixed, and noise is larger simultaneously; When rolling pearl 5 quantity is greater than 3, also easily there is rocking of multiple angle in roller 3 relatively retainer 4, rolling pearl 5 is not easily fixed, and easily produce larger vibration, noise is larger simultaneously.
Therefore adopt 3 rolling pearls 5, roller 3 can be made to keep a plane, and relative retainer 4 not easily shakes, and the structure of bearing is reliably safer, and the vibration of generation is little, and noise is little; Friction type between retainer 4 and roller 3 is rolling friction, and therefore rub little, heat yield is little.
Wherein, described internal surface is provided with joint 42, and described joint 42 connects two place's internal surfaces, and described joint 42 is connected by screw elasticity.
Be provided with prestressing force between two place's retainers 4, rolling pearl 5 is clamped between retainer 4 and roller 3, rolling pearl 5 is not easily deviate from, improve the Security of bearing; In the working procedure of bearing, can there is certain skew in joint 42, and have certain elasticity, prevents the vibration problem being rigidly connected and existing, and reduces while retainer 4 rubs with roller 3 and reduce the noise vibrating and bring.
Wherein, described retainer 4 also comprises outer surface, and the outer surface corresponding with ball grooves 43 is provided with fin 41.
Rolling pearl 5 rotation in ball grooves 43, produces larger heat, arranges fin 41 at the outer surface that ball grooves 43 is corresponding, is conducive to heat radiation.
Wherein, described retainer 4 is made up of copper material.
Copper has good thermal conductivity, better to the radiating effect of rolling pearl 5.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
