Reducer: This reducer is a kilowatt reducer mainly used with mining-type scraper conveyors. Reducer: Three-stage spiral gear reducer. The reducer is installed on the side of the conveyor head frame and arranged parallel to the conveyor. The four shafts of the reducer are the output shafts, and the splines of the four shafts drive the conveyor sprocket. The first shaft of the reducer is connected to the motor through a coupling to complete deceleration and power transmission.
It consists of a first arc bevel gear shaft, a second helical gear shaft, a third cylindrical gear shaft and a fourth output shaft. The four shafts are fixed in the upper and lower boxes of the reducer by rolling bearings. The material of the upper and lower boxes of this reducer is gray cast iron.

The reducer can be used in reverse and adopts natural cooling.
Technical requirements
. Gear accuracy level
Both bevel gears and cylindrical gears are manufactured with level 1 precision.
.Materials used for gears and shafts
The reducer shaft gears and gears are all made of high-strength alloy materials for quenching and tempering, and the tooth surfaces are carburized and quenched to extend the service life of the gears
. The four shafts of the reducer are quenched and tempered with high-strength alloy steel.
Advantages and Features
Main parameters such as center distance and nominal transmission ratio have been optimized and designed, and the main parts are interchangeable.
The gears are made of high-quality alloy steel through carburization and quenching, and the tooth surface hardness is up to 100%.
Small size, light weight, high precision, large load-bearing capacity, high efficiency, long life, high reliability, smooth transmission and low noise.
Bearing total axial clearance requirements
The first axis clearance is mm, the second axis clearance is mm, the third axis clearance is mm, and the fourth axis clearance is mm.
The clearance of each shaft bearing is adjusted by an adjusting pad.
The assembled reducers should be subjected to no-load test, temperature rise test and noise test one by one. They should meet the requirements of the general technical conditions and standards for reducers for scraper conveyors and scrapers.
