Description
Technical Field
The utility model belongs to the technical field of the bearing, mainly relate to a low friction tapered roller bearing punching press holder.
Background
The tapered roller bearing has the characteristics of wide application, various bearing types and the like, and generally comprises an outer ring, an inner ring, rollers, a retainer and other parts, the stamping retainer of the conventional tapered roller bearing generally performs slope pressing treatment on two sides of a beam between retainer window holes to generate a slope pressing surface, the rollers are in contact with the slope pressing surface, and the slope pressing surface is formed on the whole beam.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a low friction tapered roller bearing punching press holder makes it reduce the friction between roller and the holder, improves bearing life.
The purpose of the utility model can be realized by adopting the following technical scheme:
a low-friction tapered roller bearing stamping retainer is provided with a retainer body stamped by a steel plate; the retainer body is provided with a plurality of window holes which are uniformly distributed along the circumferential direction and used for mounting the tapered rollers; the retainer beam is arranged between two adjacent window holes, N grooves are formed in two sides of the retainer beam, a slope pressing surface which is used for being in contact with the roller is machined on the two sides of each retainer beam close to the inner diameter portion, the slope pressing surface is divided into a plurality of portions by a plurality of grooves which are located on the same side of the retainer beam, when the tapered roller is assembled, the roller is in contact with the retainer beam on the slope pressing surface, and the grooves in the two sides of the retainer beam are not in contact with the roller.
The thickness of the pressure slope surface is half of that of the retainer plate, and the depth of the groove is required to ensure that the roller and the retainer beam are not contacted with the beam at the groove.
The utility model provides a pair of low friction tapered roller bearing punching press holder has reduced the area of contact of roller with the holder, has increased the lubricating oil circulation, has improved the lubricating property between holder and steel ball, and when holder expansion and receipts cover, the existence of recess has reduced the metal and has flowed the change to holder fenestra size, has improved the precision of holder fenestra, has reduced the friction in the bearing working process, has improved the life-span of bearing.
