Abstract
The utility model discloses a low friction ball type slewing bearing, which comprises an outer ring, an inner ring, a steel ball and a retainer; the steel ball is arranged on a raceway formed by enclosing the inner ring and the outer ring; two spigot positioning steps for fixing the retainer are arranged on the outer diameter of the inner ring; the retainer body is an annular frame body formed by stamping a steel plate and comprises a retainer body and a pocket; the pocket is formed on the retainer body; two rabbets matched with the rabbets positioning step are arranged on the upper end face and the lower end face of the retainer, and 4 isolating arcs used for isolating the steel balls are arranged in the pocket holes. The utility model discloses reduced the area of contact between steel ball and the holder, fixed the holder and circled in slewing bearing, avoided holder and slewing bearing outer lane and inner circle to take place the friction, greatly reduced slewing bearing the frictional resistance when doing slewing motion, satisfied equipment to slewing bearing low frictional resistance's requirement.
Description
Technical Field
The utility model relates to a slewing bearing accessory field specifically is a low friction ball formula slewing bearing.
Background
The slewing bearing is an important transmission part which is necessary for machinery which needs to do relative slewing motion between two objects and simultaneously bears axial force, radial force and tipping moment, and is widely applied to the fields of engineering machinery, mining machinery, light industry packaging machinery and the like.
The main use market of the slewing bearing in the prior art is the engineering machinery market, the product of the slewing bearing is standardized and generalized, but for the light industry, such as packaging machinery or assembly lines driven by manpower, and other working occasions, the general product can not meet the use requirements that the requirement on the bearing capacity is relatively low, but the requirement on the low friction resistance is higher when the slewing bearing does slewing motion.
Disclosure of Invention
The utility model aims at providing a low friction ball formula slewing bearing can reduce its frictional resistance when doing the slewing motion.
The utility model adopts the technical proposal that: a low-friction ball type slewing bearing comprises an outer ring, an inner ring, a steel ball and a retainer;
at least one steel ball is arranged on a roller path formed by the enclosing between the inner ring and the outer ring and is separated by the retainer; an upper wear-resistant platform is arranged on the non-mounting surface of the outer ring, and a lower wear-resistant platform is arranged on the non-mounting surface of the inner ring; two spigot positioning steps for fixing the retainer are arranged on the outer diameter of the inner ring;
the retainer body is an annular frame body formed by stamping a steel plate and comprises a retainer body and a pocket; the pocket is formed on the retainer body; two rabbets matched with the rabbets positioning step are arranged on the upper end face and the lower end face of the retainer, and 4 isolating arcs used for isolating the steel balls are arranged in the pocket holes.
Furthermore, the outer diameter of the outer ring is of an L-shaped structure, and a sealing groove for mounting a sealing strip is formed in a mounting surface of the outer ring.
Furthermore, the inner diameter of the inner ring is of an L-shaped structure, and a sealing groove for mounting a sealing strip is arranged on the mounting surface of the inner ring.
The utility model discloses a low friction ball formula slewing bearing, with slewing bearing inner and outer lane and sealing strip contact site process the wear-resisting platform that the cleanliness is higher than slewing bearing installation face alone, it becomes four sections disjoint isolation arcs to process the pocket hole of holder, area of contact between steel ball and the holder has been reduced, fix the holder and circle in slewing bearing, the holder has been avoided taking place the friction with slewing bearing outer lane and inner circle, greatly reduced slewing bearing's frictional resistance when doing the slewing motion, satisfy the requirement of equipment to slewing bearing low frictional resistance.

in the figure, 1, an outer ring, 2, an inner ring, 3, a steel ball, 4, an upper wear-resistant platform, 5, a lower wear-resistant platform, 6, a retainer, 7, a spigot positioning step and 601, an isolation arc.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a low-friction ball type slewing bearing comprises an outer ring 1, an inner ring 2, a steel ball 3 and a retainer 6;
at least one steel ball 3 is arranged on a roller path formed by the enclosing between the inner ring 2 and the outer ring 1 and is separated by a retainer 6; an upper wear-resistant platform 4 is arranged on the non-mounting surface of the outer ring 1, and a lower wear-resistant platform 5 is arranged on the non-mounting surface of the inner ring 2, so that the friction coefficient of the sealing strip in contact with the end surface is reduced; the outer diameter of the inner ring 2 is provided with two spigot positioning steps 7 for fixing the retainer 6;
the retainer 6 body is an annular frame body formed by stamping steel plates and comprises a retainer 6 body and a pocket; the pocket is arranged on the body of the retainer 6; two rabbets matched with the rabbets positioning step 7 are arranged on the upper end face and the lower end face of the retainer 6, and 4 isolating arcs 601 used for isolating the steel balls 3 are arranged in the pocket holes.
The outer diameter of the outer ring 1 is of an L-shaped structure, and a sealing groove for mounting a sealing strip is formed in the mounting surface of the outer ring. The inner diameter of the inner ring 2 is of an L-shaped structure, and a sealing groove for mounting a sealing strip is arranged on the mounting surface of the inner ring. The L-shaped opening structure is used for reducing the self weight of the slewing bearing and reducing the pressure born by the slewing bearing raceway and caused by the self weight.
