CN201786917U - High-load full ball bearing - Google Patents

Abstract

The utility model relates to a high-load full ball bearing, which comprises an inner ring, an outer ring and balls, wherein the balls are placed in a raceway between the inner ring and the outer ring. The high-load full ball bearing is characterized in that a left half inner ring and a right half inner ring are connected with each other through a bolt to form the inner ring, a raceway formed by an outer peripheral surface of the inner ring and an inner peripheral surface of the outer ring is a four-point contact type peach-shaped raceway, and inner sides of the left half inner ring and the right half inner ring are concave and convex surfaces which are joggled with each other. The high-load full ball bearing has the advantages that when balls are loaded, the left half inner ring is disconnected with the right half inner ring so that the balls can be loaded smoothly, and after the bearing is fully loaded with the balls, the concave and convex surfaces of the left and right half inner rings are fastened and are fixedly connected via bolts and nuts so as to form the total inner ring. The raceway consisting of the inner ring and the outer ring is the four-point contact type peach-shaped raceway, and gaps at matching positions of the left and right half inner rings do not affect operation of the balls, thereby guaranteeing performances of the bearing, preventing the balls from being worn in advance, and prolonging service life.

Description

The full ball bearing of a kind of high capacity

Technical field

The utility model relates to a kind of bearing, the full ball bearing of particularly a kind of high capacity.

Background technique

For improving the load capacity of bearing, need fill spin in the inside and outside circle raceway with bearing, cutting one local outer ring on the outer ring usually, by removing opening that local outer ring forms with the spin raceway of packing into, more local outer ring being resetted after filling seals.It exists shortcoming to be: after resetting, local outer ring and outer ring overall co-ordination are poor, have certain matching gap, and spin is moved unsmooth in raceway, rotate not freely, easy to wear, have influenced the performance and the working life of bearing.

The model utility content

The technical problems to be solved in the utility model provides a kind of functional, full ball bearing of the nonabradable load of spin.

For solving the problems of the technologies described above, the technical solution of the utility model is: the full ball bearing of a kind of high capacity, comprise inner ring, outer ring and ball, ball places in the raceway between the inside and outside circle, and its innovative point is: described inner ring is connected and composed by bolt by a left side half inner ring and right half inner ring; The raceway that the outer peripheral surface of described inner ring and the inner peripheral surface of outer ring constitute is 4 contact-type peach shape raceways; In the described left side inner side surface of inner ring and right half inner ring be can be chimeric mutually concave, convex face structure.

Advantage of the present utility model is: during ball, left and right half inner ring does not connect at dress so that spin can pack into smoothly, fill ball after, the concave, convex face of left and right half inner ring fastens, and is connected into an inner ring integral body with bolt, nut.Because big 4 the contact-type peach shape raceways of raceway that inner ring and outer ring constitute, the gap, cooperation place of left and right half inner ring can not produce any influence to the operation of spin, has guaranteed the performance of bearing, avoids spin to wear and tear in advance, has prolonged working life.

Description of drawings

Accompanying drawing is the full ball bearing structure schematic representation of the utility model high capacity.

Embodiment

As shown in drawings, comprise outer ring 1, inner ring 2, socket head screw 3, hexagon nut 4, spin 5.

Above-mentioned inner ring 2 mainly comprises left half inner ring 2a and right half inner ring 2b, the inner side surface of this left side half inner ring 2a and right half inner ring 2b is respectively equipped with concave surface and convex surface, the concave, convex face of a left side half inner ring 2a and right half inner ring 2b can be chimeric mutually, and can be connected into an integral inner ring 2 by socket head screw 3 and hexagon nut 4.

The raceway that the inner peripheral surface of the outer peripheral surface of inner ring 2 and outer ring 1 constitutes is 4 contact-type peach shape raceways, fills spin 5 in the raceway.During spin 5, left half inner ring 2a and right half inner ring 2b do not fasten earlier at dress, fasten after treating spin 5 filled raceway again, and utilize socket head screw 3 and hexagon nut 4 to be connected and fixed.4 contact-type peach shape raceways make the gap, cooperation place of left half inner ring 2a and right half inner ring 2b can not produce any influence to the operation of spin 5, have guaranteed the performance of bearing, avoid spin to wear and tear in advance, have prolonged working life.

Claims (1)

1. the full ball bearing of a high capacity comprises inner ring, outer ring and ball, and ball places in the raceway between the inside and outside circle, and it is characterized in that: described inner ring is connected and composed by bolt by a left side half inner ring and right half inner ring; The raceway that the outer peripheral surface of described inner ring and the inner peripheral surface of outer ring constitute is 4 contact-type peach shape raceways; In the described left side inner side surface of inner ring and right half inner ring be can be chimeric mutually concave, convex face structure.
