Composite carrier roller of rubber belt ore conveyor

Abstract

The invention discloses a composite carrier roller of a rubber belt ore conveyor and aims to improve the ore conveying reliability and prolong the service life of the carrier roller of the rubber belt ore conveyor. The composite carrier roller comprises a middle carrier roller shaft, hollow conical carrier rollers, wear-resistant rubber, bearing seats, supporting covers, a carrier roller shaft, lip-shaped sealing rings, lubricating oil cups, shaft end ring washers, rolling bearings and sealing covers; the middle carrier roller shaft is cylindrical, the hollow conical carrier rollers are arranged at two ends of the middle carrier roller shaft, and the middle carrier roller shaft is connected with the hollow conical carrier rollers in a V-shaped groove welding way; the surfaces of grooves are in smooth circular arc transition; two outer ends of the hollow conical carrier rollers are provided with the supporting covers, the rolling bearings are arranged at two ends of the carrier roller shaft, two ends of the carrier roller shaft are provided with annular grooves, the shaft end ring washers are arranged on the annular grooves at two ends of the carrier roller shaft, the bearing seats are arranged at two ends of the carrier roller shaft through the rolling bearings, the lip-shaped sealing rings are used as sealing devices for protecting the rolling bearings at the inner sides of the bearing seats, two ends of the carrier roller shaft are provided with anti-creeping steps, and the bearing seats are provided with the lubricating oil cups; and the wear-resistant rubber is coated outside the hollow conical carrier rollers.

Description

technical field [0001] The invention relates to a composite roller device for a belt conveyor in a mine. Background technique [0002] The belt conveyor is an important transportation equipment for many iron ores in my country. Usually, multiple belt conveyors are used to connect the upper and lower processes of iron ore and transport the ore. However, in the production process, there are often problems such as frequent idler failures, fast wear, and mud ore easily destroying the sealing ring and entering the bearing, resulting in poor lubrication of the bearing, resulting in large machine vibration, heavy load, and even sudden accidents such as tearing of the rubber belt. . One of the main reasons is that the roller structure of the belt conveyor is thin, insufficient in strength and rigidity, and easy to twist and deform. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide...

Problems solved by technology

However, in the production process, there are often problems such as frequent idler failures, fast wear, and mud ore easily destroying the sealing ring and entering the bearing, resulting in poor lubrication of the bearing, resulting in large machine vibration, heavy load, and even sudden accidents such as tearing of the rubber belt.

One of the main reasons is that the structure of the roller of the belt conveyor is thin, the strength and rigidity are insufficient, and it is easy to distort and deform.
