Description

Main shaft adds the mining dust catcher of key

Technical field

The utility model relates to the mining dust catcher that a kind of main shaft adds key.

Background technology

In the field such as colliery, metallurgy, the equipment such as hopper, feed bin all adopts and unloads the equipment such as ash, dedusting, the use of these equipment is very frequent, intensity is also very large, and due to base bearing too large by moment of torsion, main shaft easily damages, cause maintenance cycle very short, cost of production is high, and production efficiency is low.

Utility model content

The purpose of this utility model is to provide the mining dust catcher that a kind of main shaft adds key, and apparatus structure is simple, and handling safety is reliable, extension device application life, reduces maintenance frequency, greatly reduces costs.

Main shaft described in the utility model adds the mining dust catcher of key, comprises motor, and motor is connected with reductor, and reductor is connected with impeller assembly, arranges bearing (ball) cover after impeller assembly; Arrange main shaft and the first axle in mining dust catcher, main shaft runs through bearing (ball) cover, impeller assembly and reducer pedestal, and the first axle is in reducer pedestal; Main shaft is provided with the first keyway, and the another side of the main shaft relative with the first keyway arranges the second keyway; Reductor rear end arranges reducer pedestal.

Main shaft is connected by shaft coupling with the first axle.

Flange joint is passed through between motor and reductor.

Main shaft arranges specification identical, the keyway that position is opposing, greatly can increase the ability of base bearing by torsional forces, reduce the wearing and tearing to main shaft, extend the life-span of main shaft.

Compared with prior art, the utility model has following beneficial effect:

The utility model main shaft adds the mining dust catcher of key, and apparatus structure is simple, and handling safety is reliable, extension device application life, reduces maintenance frequency, greatly reduces costs.
