Abstract

The utility model relates to the technical field of bearings, and a tapered roller composite bearing is disclosed, including bearing inner race and bearing inner race, the bearing inner race is equipped with two, and bearing inner race movable sleeve establishes in two bearing inner races outsidely, and two bearing inner race lateral walls all have been seted up transversal coniform roller groove of personally submitting with the bearing inner race inside wall, and roller inslot portion movable mounting has the tapered roller rather than the looks adaptation, and bearing inner race both ends all can be dismantled and install and keep off the ring. This tapered roller composite bearing, through bearing inner race and bearing inner race disconnect-type design, simple structure makes the utility model discloses simple to operate keeps off the ring through demountable installation in bearing inner race and replaces traditional overall structure, can dismantle the fender ring of its one side and change when one of them tapered roller damages, reduces the wasting of resources.

Description

Tapered roller composite bearing

Technical Field

The utility model relates to a bearing technical field specifically is a tapered roller composite bearing.

Background

In the industries of automobiles, rolling mills, mines, metallurgy, plastic machinery and the like, matched bearing design is required, tapered roller bearings are often used and mainly bear radial and axial combined loads which mainly take the radial direction, the bearing capacity depends on the roller path angle of an outer ring, and the larger the angle is, the larger the bearing capacity is. The common outer ring of the double-row tapered roller bearing is of an integral structure, and once the outer ring is damaged, the whole bearing needs to be replaced to cause resource waste when the requirement of high load and high rotating speed is met.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a tapered roller composite bearing, in case damage, just need to change whole bearing, cause the problem of wasting of resources to the current ordinary double-row tapered roller bearing who proposes in having solved above-mentioned background art.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

the utility model provides a tapered roller composite bearing, includes bearing inner race and bearing outer lane, and the bearing inner race is equipped with two, and bearing outer lane movable sleeve establishes two bearing inner races outsidely, and two bearing inner race lateral walls all set up transversal personally submitting coniform roller groove with the bearing outer lane inside wall, and roller inslot movable mounting has the tapered roller rather than the looks adaptation, and bearing outer lane both ends all can be dismantled and install and keep off the ring.

Furthermore, the cross sections of the two bearing inner rings are conical, and the necking ends of the two bearing inner rings are oppositely and symmetrically arranged in the bearing outer ring.

Furthermore, a limiting ring is arranged between the two bearing inner rings, and the inner diameter of the limiting ring is equal to the inner diameter of the bearing outer ring.

Furthermore, the outer walls of the two bearing inner rings are sleeved with retainers, and the retainers are positioned between the bearing inner rings and the bearing outer rings.

Furthermore, a plurality of fastening bolts are arranged on the baffle ring, a plurality of threaded holes matched with the fastening bolts are formed in the baffle ring and the two ends of the bearing outer ring, and the inner diameter of the baffle ring is larger than the inner diameter of the bearing inner ring and smaller than the outer diameter of the bearing inner ring.

(III) advantageous effects

The utility model provides a tapered roller composite bearing possesses following beneficial effect:

this tapered roller composite bearing, through bearing inner race and bearing inner race disconnect-type design, simple structure makes the utility model discloses simple to operate keeps off the ring through demountable installation in bearing inner race and replaces traditional overall structure, can dismantle the fender ring of its one side and change when one of them tapered roller damages, reduces the wasting of resources.
