Bearing box of heavy slurry pump and shafting transmission structure thereof

Abstract

The invention discloses a bearing box of a heavy slurry pump and a shafting transmission structure thereof and particularly relates to an integral bearing box of a horizontal abrasion-resistant slurry pump and a shafting transmission structure thereof, which belongs to the field of a mechanical transmission technique. The shafting transmission structure disclosed by the invention comprises a pumpshaft, a cooler, a front bearing gland, a rear bearing gland, a front dustproof disk, a rear dustproof disk, a carrier, a bearing box, a second regulating bolt, rear locking stud nuts and a compression ring. In order to reduce the machining area and matching area among a carrier body, a bearing bush and a carrier cover, the bearing bush and the carrier cover are cast into an integral; in order toconveniently regulate the gap between an impeller and an flow passage component, the arrangement of the second regulating bolt is optimized; and a second shaft regulating bolt is changed to be arranged between the rear lower end of the bearing box and the rear rib plate of the carrier, and the regulating space is enlarged, therefore thicker and longer bolts, studs and nuts can be adopted, therebyenlarging the regulating space. In the invention, the machining load can be reduced; the machining cost is lowered; the machining and finishing accuracy is improved; the oil leakage risk is reduced; and the coaxially of the bearing box and the carrier can be better guaranteed.

Description

technical field [0001] The invention relates to a bearing box and a shaft transmission structure of a heavy-duty slurry pump, in particular to an integral bearing box and a shaft transmission structure of a horizontal wear-resistant slurry pump, belonging to the technical field of mechanical transmission. Background technique [0002] Slurry pump is a kind of centrifugal pump that can transport the slurry containing large particle size impurities, or slurry containing granular abrasive and corrosive impurities. It is mainly used in metallurgy, petrochemical industry, mining, coal mine, building materials, light industry, Papermaking and other industries transport material (slag) slurry that contains particles and is corrosive. The transmission form of the horizontal slurry pump is mainly the bracket type transmission. The motor end can adopt various connection methods such as coupling, pulley or adding a hydraulic coupling. The structure is suitable for series or parallel c...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the bearing box and its bracket structure of the heavy-duty slurry pump have large processing area, high processing cost, difficulty in ensuring processing accuracy and coaxiality, poor interchangeability of parts, high risk of oil leakage, and difficulty in adjusting the impeller and The purpose of the present invention is to solve the above-mentioned problems and disclose a heavy-duty slurry pump bearing box and its shaft transmission structure.
