Abstract

A kind of sealed double-row full-complement cylinder roller bearing with spherical outside surface, including outer ring and inner ring, it is uniformly distributed with two column rolling elements along the circumference between outer ring and inner ring, seal assembly is respectively equipped on the outside of each column rolling element, the seal assembly includes the dustproof cover being mounted between outer ring and inner ring, it is equipped with annular groove in dustproof cover, is placed with the circlip being set on the outside of inner ring in a ring groove；By the way that circlip to be hidden to the structure for being placed in dustproof cover and original dustproof cover and outer ring being replaced to be interference fitted, the axial space of bearing is saved, the rated load of bearing is increased；It prevents circlip from sliding in bearing action between inner ring and outer ring by the limiting slot of inner ring two sides, guarantees the normal use of bearing；Axial displacement is sealed and limited to bearing by dustproof cover and circlip, has the advantages that rated load is big, long service life.

Description

A kind of sealed double-row full-complement cylinder roller bearing with spherical outside surface

Technical field:

The utility model relates to a kind of sealed double-row full-complement cylinder roller bearing with spherical outside surfaces.

Background technique:

A kind of sealed double-row full-complement cylinder roller bearing with spherical outside surface is a kind of structure type of cylindrical bearing, such as Fig. 1 institute Show, it includes outer ring 1, inner ring 2, rolling element 3, dustproof cover 4 and circlip 6, and wherein dustproof cover plays sealing function, elasticity gear Enclose the effect of component axial displacement outside limitation bearing.Due to the design of this structure, axial space be remove it is dust-proof Lid obtains after being added with circlip axial dimension, considers further that length dimension and rib size of rolling element etc. on this basis, The design for limiting rolling element length dimension in this way, rolls the reduction of body length, to influence the rated load of bearing, bearing The reduction of rated load reduces the service life of bearing；And because of the limitation of dustproof cover and circlip in the axial direction, Bearing axial displacement is reduced, the axial adjustability of bearing is influenced, also will affect the service life of bearing.

Utility model content:

The utility model in order to make up for the deficiencies of the prior art, provides a kind of sealed double-row full-complement cylinder roller ectosphere Spherical bearing, it is reasonable in design, bearing axial space is saved, rolling body length has been increase accordingly, increases the specified of bearing Load improves the axial adjustability of bearing, increases the service life of bearing, solves existing in the prior art ask Topic.

Used technical solution is the utility model to solve above-mentioned technical problem:

A kind of sealed double-row full-complement cylinder roller bearing with spherical outside surface, including outer ring and inner ring, between outer ring and inner ring It is uniformly distributed with two column rolling elements along the circumference, is respectively equipped with seal assembly on the outside of each column rolling element, it is characterised in that: the sealing Component includes the dustproof cover being mounted between outer ring and inner ring, and annular groove is equipped in dustproof cover, is placed with set in a ring groove The circlip being located on the outside of inner ring.

It is equipped with annular retaining ring respectively inwards at the inner surface both ends of outer ring.

Respectively there is a fitting plane at the outer surface of dustproof cover is 180 ° opposite, two fitting planes are parallel, two fitting planes Between linear distance matched with the internal diameter of annular retaining ring.

The limiting slot matched with circlip is respectively equipped at the outer surface both ends of inner ring.

The limiting slot is vertically arranged far from the groove face of circlip, and the groove face close to circlip is obliquely installed.

The utility model using the above structure, by circlip is hidden be placed in dustproof cover it is original anti-to replace The structure of dirt lid and outer ring interference fit, saves the axial space of bearing, increases the rated load of bearing；Pass through inner ring two The limiting slot of side prevents circlip from sliding in bearing action between inner ring and outer ring, guarantees the normal use of bearing；It is logical It crosses dustproof cover and circlip and axial displacement is sealed and limited to bearing, have rated load big, with long service life excellent Point.

Specific embodiment:

In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality It is described in detail with novel.

As shown in figures 2-6, a kind of sealed double-row full-complement cylinder roller bearing with spherical outside surface, including outer ring 1 and inner ring 2, It is uniformly distributed with two column rolling elements 3 along the circumference between outer ring 1 and inner ring 2, is respectively equipped with sealing group in the outside of each column rolling element 3 Part, it is characterised in that: the seal assembly includes the dustproof cover 4 being mounted between outer ring 1 and inner ring 2, is equipped in dustproof cover 4 Annular groove 5 is placed with the circlip 6 for being set in 2 outside of inner ring in annular groove 5.

It is equipped with annular retaining ring 7 respectively inwards at the inner surface both ends of outer ring 1.

Respectively there is a fitting plane 8 at the outer surface of dustproof cover 4 is 180 ° opposite, two fitting planes 8 are parallel, and two assembly are flat Linear distance between face 8 is matched with the internal diameter of annular retaining ring 7.

The limiting slot 9 matched with circlip 6 is respectively equipped at the outer surface both ends of inner ring 2.

The limiting slot 9 is vertically arranged far from the groove face of circlip 7, and the groove face close to circlip 7 is obliquely installed.

The assembling steps of sealed double-row full-complement cylinder roller bearing with spherical outside surface are as follows:

S1, circlip 6 is placed in the annular groove 5 of dustproof cover 4；

S2, it is matched using fitting plane 8 disposed in parallel on dustproof cover 4 with the annular retaining ring 7 on 1 inner surface of outer ring, Dustproof cover 4 is vertically put into the side of outer ring 1；

S3, rotation dustproof cover 4, dustproof cover 4 is placed in outer ring 1, a column rolling element 3 is packed into outer ring 1；

S4, the step of S2 and S3 is repeated, dustproof cover 4 is mounted on to the other side of outer ring 1, and be packed into another column rolling element 3.

S5, it is put into inner ring 2.

The fitting plane 8 on annular retaining ring 7 and dustproof cover 4 on outer ring 1 matches, and improves original mounting means, Bearing axial space is saved, the length of rolling element 3 is increased, increases the rated load of bearing, improves the axial direction of bearing Regulating power improves the service life of bearing；The groove face being vertically arranged on 2 outer surface both ends limiting slot 9 of inner ring can be to prevent Only circlip 6 falls off from bearing, during the groove face being obliquely installed can guarantee that dustproof cover 4 can return to after shifting Between initial position.

Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model It protects in range.

Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
