Double-row cylindrical roller split bearing with spherical outer ring

Abstract

The invention relates to a double-row cylindrical roller split bearing with a spherical outer ring. The double-row cylindrical roller split bearing comprises an outer ring, rollers, a retainer and an inner ring; the outer ring consists of two double half outer rings which are connected through outer ring fasteners; the inner ring consists of two double half inner rings which are connected together; a double-row raceway is formed between the inner wall of the outer ring and the outer wall of the inner ring; and the rollers are arranged in the double-row raceway through the retainer. Compared with the prior art, the double-row cylindrical roller split bearing with a spherical outer ring replaces a common cylindrical roller bearing and is applied to a converter device, the bearing is convenient to install and maintain, the time and the money for exchanging bearings are greatly reduced; because the oil lubrication is changed to grease lubrication, the lubrication system is reduced, the cost is lowered, the lubrication environment is improved, and the working environment is more comfortable, so that the iron and steel industry is improved to a new stage and reaches the advanced level home and abroad.

Description

technical field [0001] The invention relates to a bearing, in particular to a split bearing with spherical double-row cylindrical rollers on the outer ring. Background technique [0002] At present, in the iron and steel industry, the bearing is an important part of the converter equipment. It is installed on the trunnion and used in the harsh environment of high temperature, high load, corrosion and corrosion. The integral cylindrical roller bearing is usually used. This bearing has the following disadvantages: 1. 1. The outer ring is a cylindrical surface, which has no self-aligning effect, resulting in low service life; 2. It is difficult to replace the bearing during maintenance, which reduces the work efficiency. Contents of the invention [0003] The object of the present invention is to provide a spherical double row cylindrical roller split bearing with a spherical outer ring that has a longer service life and is more convenient to use in order to overcome the abov...
