DBY Series Bevel-Helical Gear Reducer

Overview

Bevel-Helical gear reducer (hereinafter referred to as the reducer) is used for transmissions in which the input shaft and the output shaft are arranged in a vertical direction.

Mainly used in belt conveyors and various transportation machinery, but also in the transmission mechanism of various general machinery such as coal, metallurgy, mining, chemical industry, building materials, light industry, petroleum and so on.

Performance Characteristics

High carrying capacity, low noise, small size, light weight, high efficiency and long service life.

Parameter Range

DBY, DBYK, and DBZ reducers each have 12 specifications, the nominal center distance is: 160, 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560mm; each specification has 5 types The transmission ratio (8, 10, 11.2, 12.5, 14), two rotation directions, four assembly types, respectively constitute 240 types of reducers.

DCY, DCYK, and DCZ type reducers each have 15 specifications, the nominal center distance is: 160, 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560, 630, 710, 800mm; Each specification has 11 transmission ratios (16, 18, 20, 22.4, 25, 28, 31.5, 35.5, 40, 45, 50), two rotation directions, four assembly types, and 660 types of reducers.

This reducer series can meet all the power requirements of TD and DX belt conveyors and other transportation machinery and the working range of 0.8~6.5m/s belt speed.

Structure

The first-stage transmission of the reducer is Gleason-made spiral bevel gears, and the second and third-stage transmissions are involute cylindrical helical gears.

Lubrication of reducer: In general, the gears and bearings of the reducer are lubricated by splashing oil pool and naturally cooled. Only when the working equilibrium temperature of the reducer exceeds the specified value or the carrying power exceeds the thermal power PG1, the circulating lubrication or the oil pool lubrication with the cooling pipe is used.
