Problems solved by technology

At present, a set of self-aligning roller bearings or a pair of tapered roller bearings are used in China. The use of self-aligning roller bearings has low reliability under vibration loads, and the use of a pair of tapered roller bearings cannot meet the bearing life under the condition of shaft eccentricity. , the installation is more difficult

Embodiment 1

[0014] according to figure 1 As shown, a double-row tapered roller bearing capable of bearing axial and radial combined loads described in this embodiment includes an inner ring 1, an outer ring 2, and two sets of rollers installed between the inner ring and the outer ring. Each group of rollers is respectively installed on a cage 4; the outer wall 21 of the outer ring is a convex spherical surface.

Embodiment 2

[0016] according to figure 1 and figure 2 As shown, the installation structure of a double-row tapered roller bearing capable of bearing axial and radial combined loads described in this embodiment,

[0017] It includes an organic casing 5, a double-row tapered roller bearing P and an output shaft 6.

[0018] The double-row tapered roller bearing includes an inner ring 1, an outer ring 2, and two sets of rollers 3 installed between the inner ring and the outer ring, and each set of rollers is respectively installed on a cage 4; The outer wall 21 of the outer ring is a convex spherical surface; the casing is formed with an inner concave spherical surface that is slidably connected with the outer wall of the outer ring; the output shaft is connected with the inner ring.

[0019] The outer wall of the outer ring is a convex spherical surface, which is essentially used as the inner ring of the joint bearing and plays a role of self-alignment; the bearing has improved radial and...

Abstract

The invention discloses a double row tapered roller bearing and an installing structure thereof. The double row tapered roller bearing comprises an inner ring, an outer ring and two sets of rollers installed between the inner ring and the outer ring; each set of rollers are installed on a holder; and the outer wall of the outer ring is a spherical face protruding outwards. The outer wall of the outer ring is the spherical face protruding outwards, is used as an inner ring of a joint bearing in essence and has an alignment effect. The bearing improves the radial and axial bearing capacity, and performance is more excellent and obvious in a vibration impacting load environment. The requirement of the bearing for the assembly precision of a complete machine is lowered, assembly is easy, the structure is simple, and universality is high.

Description

technical field [0001] The invention belongs to the field of bearing structures, and in particular relates to a non-standard outer spherical double-row tapered roller bearing used for mixer truck reducers and other engineering machinery. Background technique [0002] A bearing is a component used in a rotating mechanism to support, reduce friction and bear loads. This product is mainly designed for mixer truck reducer and other construction machinery. Because it can bear large radial load, axial load and impact load, it is easy to assemble and disassemble, and has a strong bearing capacity, so it is widely used in mixer truck reducer, etc. construction machinery. At present, a set of self-aligning roller bearings or a pair of tapered roller bearings are used in China. The use of self-aligning roller bearings has low reliability under vibration loads, and the use of a pair of tapered roller bearings cannot meet the bearing life under the condition of shaft eccentricity. , t...
