Abstract
The utility model provides a mute type deep groove ball bearing for a motor, which comprises an outer ring (1), steel balls (2), a retaining frame (3), a sealing ring (4) and inner rings (5), wherein an outer roller way is arranged at the center of the inner end face of the outer ring; the curvature radius of the outer roller way is equal to the product of 0.55 and the radius of the steel balls; an inner roller way is arranged at the center of the outer end face of the inner ring; the curvature radius of the inner roller way is equal to the product of 0.53 and the radius of the steel balls; a plurality of steel balls are arranged between the outer roller way and the inner roller way and limited by the retaining frame; and irregular trapezoidal grooves used for installing the sealing rings are arranged at two ends of the inner end face of the outer ring and the outer end face of the inner ring. In the mute type deep groove ball bearing, four design parameters of pockets of the retaining frame are optimized; the mute type deep groove ball bearing is beneficial for effectively reducing centrifugal force generated during the high-speed rotation of the deep groove ball bearing; therefore, the friction between the steel balls and the pockets of the retaining frame is reduced, and heat generation, the scratch of the surfaces of the steel balls, and produced vibration or noise are reduced.
Description
Technical field
The utility model belongs to technical field of bearings, especially a kind of motor squelch type deep groove ball bearing.
Background technique
Motor generally uses at household electric appliance with deep groove ball bearing, and its working condition is the running of underloading, middling speed, and the load that bearing bears is general≤0.1%Cr (dynamic load rating of bearing), that is to say that the work loads of bearing is very little, fatigue ruption can not take place generally.
But the dynamic load rating that traditional motor is pursued bearing with deep groove ball bearing is bigger, the fatigue life of bearing is longer, therefore may cause the increase of bearing vibration, noise and friction torque, environment is caused adverse effect, and the power loss of household electric appliance is increased.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of motor squelch type deep groove ball bearing, and it is little that this squelch type deep groove ball bearing has friction torque, and vibrating noise is little, the characteristics of life-span length.
In order to realize the foregoing invention purpose, the utility model adopts following technological scheme:
Described motor comprises outer ring, steel ball, retainer, seal ring and inner ring with the squelch type deep groove ball bearing, the interior edge face center design of outer ring has outer raceway, the radius of curvature of described outer raceway equals 0.55 and multiply by the steel ball radius, center, the exterior edge face design of inner ring has interior raceway, the radius of curvature of described interior raceway equals 0.53 and multiply by the steel ball radius, outside described raceway and described in be equipped with several steel balls between the raceway, spacing between several steel balls by retainer, in the design of the two ends of outer ring interior edge face and inner ring exterior edge face the irregular trapezoidal groove that seal ring is installed is arranged.
Described motor squelch type deep groove ball bearing, two of the pocket hole of retainer seamlessly transit chamfering and equate, and described two seamlessly transit the pocket hole height of chamfering, retainer and the pocket hole radius of curvature of retainer is determined by the value of steel ball size.
Owing to adopted technological scheme as mentioned above, the utility model produces following good effect:
1, steel ball size, steel ball number and steel ball are installed in pitch diameter behind the retainer through optimal design with choose, can effectively reduce the friction torque of deep groove ball bearing or the heating of control deep groove ball bearing, the power consumption of deep groove ball bearing can be reduced greatly.
2, the Curvature Radius Coefficient of outer raceway and interior raceway is optimized vibration or the noise that design can reduce deep groove ball bearing, thereby and revolving of steel ball is rolled than the heating that reduces to reduce deep groove ball bearing.
3, the shifting amount in retainer pocket hole is to influence the key factor that deep groove ball bearing produces noise, four design parameters in retainer pocket hole are optimized design, help effectively reducing run up the down generation of centrifugal force of deep groove ball bearing, reduce the friction at steel ball and retainer pocket hole place, reduced vibration or noise that heating, steel ball surface scratch, produce.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the expansion schematic representation of retainer;
Fig. 3 is the I place enlarged diagram of Fig. 2.
Among the above-mentioned figure: the 1-outer ring; The 2-steel ball; The 3-retainer; The 4-seal ring; The 5-inner ring.
Embodiment
In conjunction with Fig. 1, motor of the present utility model comprises outer ring 1, steel ball 2, retainer 3, seal ring 4 and inner ring 5 with the squelch type deep groove ball bearing.
The design of the interior edge face of outer ring 1 center has outer raceway, the radius of curvature of described outer raceway to equal 0.55 to multiply by the steel ball radius, wherein 0.55 be the Curvature Radius Coefficient of outer raceway.
The design of center, the exterior edge face of inner ring has interior raceway, described in the radius of curvature of raceway equal 0.53 and multiply by the steel ball radius, wherein 0.53 be the Curvature Radius Coefficient of interior raceway.
The Curvature Radius Coefficient of outer raceway and the Curvature Radius Coefficient of interior raceway can reduce the vibration or the noise of deep groove ball bearing through optimization of matching, thereby and revolving of steel ball are rolled than the heating that reduces to reduce deep groove ball bearing.
Outside described raceway and described in be equipped with several steel balls 2 between the raceway, spacing between several steel balls 2 by retainer 3.The number that is provided with of steel ball draws by optimization, is the deep groove ball bearing of 6309-2RZ as model, and it is 8 that its steel ball is provided with number, and the diameter of steel ball is got 16.669mm, and pitch diameter of ball set Dwp gets 72mm.The diameter of steel ball, the quantity of steel ball and steel ball are installed in the pitch diameter process optimal design behind the retainer and choose, can effectively reduce the friction torque of deep groove ball bearing or the heating of control deep groove ball bearing, the power consumption of deep groove ball bearing can be reduced greatly.
In the design of the two ends of outer ring interior edge face and inner ring exterior edge face the irregular trapezoidal groove that seal ring 4 is installed is arranged, the irregular trapezoidal groove at interior edge face two ends, outer ring is symmetrical arranged, and the irregular trapezoidal groove at two ends, inner ring exterior edge face also is symmetrical arranged.
In conjunction with Fig. 2-3, retainer pocket of the present utility model hole has increased by four design parameters, be that retainer pocket hole seamlessly transits chamfering r1 and r2, retainer pocket hole height K and retainer pocket hole radius of curvature SR, the thickness S of retainer is a conventional parameter, and the value of r1, r2, K and SR and steel ball size is determined.Such as at steel ball size being desirable r1=r2=0.3 mm under the 16.669mm, and K=8.68 mm, SR=8.74 mm, r1, r2, K and SR value mainly are in order to control the radial-play amount of deep groove ball bearing, to reduce the vibration and the noise of deep groove ball bearing.
