Abstract
The invention relates to a special single-row deep groove ball bearing for a guide wheel of an automobile door, which comprises an outer ring, an inner ring, rolling bodies and a connecting mandrel, wherein a seal ring is fixed on the outer ring; and excircle plastic is arranged on the outer ring. The special single-row deep groove ball bearing is characterized in that a retainer is also included; the inner ring is an integral inner ring; the rolling bodies are spherical ones which are uniformly distributed between the outer ring and the inner ring; the inner ring is mounted and fixed through the connecting mandrel; and the spherical rolling bodies are uniformly spaced by the retainer. According to the invention, the original two separable inner rings are converted into one integral inner ring; and the meanwhile, the ball bearing is changed from the original full balls with no retainer to full balls with the retainer. Thus, the bearing can bear the corresponding load, the rotation resistance is reduced, and the bearing is less prone to abrasion in case of high-load application. When the bearing is mounted on an automobile door, the resistance is smaller than before during movement of the door, and the service life of the bearing is longer than before; and due to satisfactory matching, no vibration or noise is generated when the automobile runs at a high speed.
Description
Technical field
The single-groove grooved ball bearing that the present invention relates to the models such as car door guide wheel special-purpose 5F1721F-2RS1STN1,6F2126F-2RS1STN1,10F3228F-2RS1STN1,8F2426F-2RS1STN1,6F2124F-2RS1STN1, is applied to automotive field.
Background technique
For business car moving door guide wheel bearing, mainly by outer ring, outer ring plastic cement, two separable inner rings, rolling element, grease, seal ring, connecting mandrels, formed.Employing is installed rolling element between outer ring and inner ring, rolling element adopts ball-type, fills up after two separated inner rings being installed to riveting by connecting mandrel after ball and is fixed, and seal ring is fixed on above outer ring, play dustproof and prevent that leaking outside effect of grease, grease from playing the effects such as lubricated and formation oil film.Former being assemblied in above business car moving door of this bearing used as guide wheel, because this bearing does not adopt retainer, inner ring is again to be formed by two halves riveting, when bearing rotates, resistance is excessive, use a period of time rear bearing wearing and tearing very fast, can produce axially and radial clearance, thereby make the gap of business car door also can become large, during high-speed running automobile, car door can produce vibration and noise.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of car door guide wheel special-purpose single-groove grooved ball bearing, this bearing can reduce the resistance that bearing rotates, and can bear corresponding load, reduce again the resistance rotating, can under high loading is used, be not easy wearing and tearing.
The technological scheme providing according to type of the present invention, the special-purpose single-groove grooved ball bearing of car door guide wheel comprises outer ring, inner ring, rolling element, seal ring, connecting mandrel and cylindrical plastic cement; Described seal ring is fixed on above outer ring, and cylindrical plastic cement is arranged on outer ring; Feature is: also comprise retainer, described inner ring is integrated type inner ring, and rolling element adopts ball-type, distributes and is arranged between outer ring and inner ring uniformly, and inner ring is installed fixing by connecting mandrel, and described retainer separates spherical rolling body uniformly.
As a further improvement on the present invention, the groove curvature of the curvature of described rolling element and inner ring, outer ring is consistent.
As a further improvement on the present invention, bearing top circle outside dimension is φ 17.45mm-φ 32mm, and width dimensions is 8mm-9mm, and endoporus internal diameter size is φ 4.65mm-10mm, and the spherical rolling diameter of bearing is φ 2.381mm-3.5mm.Connecting mandrel length dimension is 20.45mm-27.6mm, installation shaft socket end diameter phi 4.65mm-φ 10mm, and length is 8mm-9.6mm, and Outside diameter is φ 10mm-φ 14mm, and length is 3.45mm-11mm, and end diameter is φ 5.95mm-φ 8.93mm.
Type of the present invention is compared and is had the following advantages with original structure:
Profile shaft bearing structure of the present invention changes single-groove grooved ball bearing into, make original inner ring by two separable conversions for an integral inner ring, simultaneously original completely ball has made to have now retainer into without retainer.This bearing not only can bear corresponding load, has reduced again the resistance rotating, and bearing is not easy wearing and tearing under high loading is used.Bearing is installed to above car door, little when door is mobile before resistance ratios, the life-span that bearing uses than before extend, because mixing ratio is better, during high-speed running automobile, can not produce vibration and noise yet.
Accompanying drawing explanation
Fig. 1 is automobile moving door guide wheel special bearing structural representation of the present invention.
Embodiment
Type of the present invention is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, comprise outer ring 1, inner ring 2, rolling element 3, grease, seal ring 5, connecting mandrel 6 and cylindrical plastic cement 7; Described seal ring 5 is fixed on above outer ring 1, and cylindrical plastic cement 7 is arranged on outer ring 1; Also comprise retainer 4, described inner ring 2 is integrated type inner ring, and rolling element 3 adopts ball-type, distributes and is arranged between outer ring 1 and inner ring 2 uniformly, and inner ring 2 is installed fixing by connecting mandrel 6,
Described retainer 4 is arranged on rolling element 3, and described retainer 4 separates spherical rolling body 3 uniformly.The groove curvature of the curvature of described rolling element 3 and inner ring, outer ring is consistent.
Described bearing top circle outside dimension is φ 17.45mm-φ 32mm, and width dimensions is 8mm-9mm, and endoporus internal diameter size is φ 4.65mm-10mm, and the spherical rolling diameter of bearing is φ 2.381mm-3.5mm.Connecting mandrel length dimension is 20.45mm-27.6mm,, installation shaft socket end diameter phi 4.65mm-φ 10mm, length is 8mm-9.6mm, and Outside diameter is φ 10mm-φ 14mm, and length is 3.45mm-11mm, and end diameter is φ 5.95mm-φ 8.93mm.
The present invention improves original bearing structure, has increased retainer 4, and the number of rolling element 3 is than original minimizing to some extent, but is evenly distributed between outer ring 1 and inner ring 2, while having avoided bearing to rotate, and the wearing and tearing that the collision between rolling element produces.The interior profile size constancy of bearing, the inner retainer that increases, overall structure is consistent with deep groove ball bearing.Inner ring is as a whole, can be because of the excessive axial and radial clearance of the bad production of riveting.Rolling element adopts ball-type, be evenly distributed between outer ring and inner ring, the curvature of rolling element and the groove curvature of inside and outside circle are consistent, increased like this surface of contact of rolling element, this bearing makes the stressed even of each rolling element simultaneously, thereby reduced the resistance that bearing rotates, so can bear corresponding load, reduced again the resistance rotating, bearing is not easy wearing and tearing under high loading is used.Seal ring is fixed on above outer ring, plays dustproof and prevents that leaking outside effect of grease, grease from playing the effects such as lubricated and formation oil film.
