Product Details

Uses

Conical cylindrical gear reducer (hereinafter referred to as reducer) for the input shaft and output shaft in a vertical direction of the transmission device. Mainly used in belt conveyors and various transportation machinery, but also used in coal, metallurgy, mining, chemical, building materials, light industry, oil and other general machinery transmission mechanism.


Performance characteristics

The utility model has the advantages of high load capacity, low noise, small size, light weight, high efficiency and long service life.


Parameter range

There are 12 specifications for DBY, DBYK and DBZ reducers. The nominal center distance is 160180200224250280315355400

450500560mm: each specification has 5 kinds of transmission ratio (8, 10112125, 14), two kinds of rotation, four kinds of assembly form 240 kinds of reducer respectively.

There are 15 specifications for DCY, DCYK and DCZ reducers. The nominal center distance is 160180200224250280315355400.

450500560630710800mm: each specification has 11 transmission ratios (16, 18, 20, 22.4, 25, 28315, 35.5, 40,45), two kinds of rotation, four types of assembly, respectively, consisting of 660 kinds of reducer.

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


Structure

The first stage transmission of the reducer is Gleason spiral bevel gear, and the second and third stage gear is involute cylindrical helical gear.

Reducer lubrication: generally idle conditions, reducer gear and bearings, the use of oil splash lubrication, natural cooling. Only when the working balance temperature of the reducer exceeds the specified value or the carrying capacity exceeds the heat power pG, the circulating lubrication or oil tank with cooling pipe is adopted.


Models and markings

The type of reducer is composed of type code, nominal center distance, a (final center distance), nominal transmission ratio, assembly type code number, input shaft and rotation direction code.

D- belt conveyor class group code B-, two stage transmission, c- three stage transmission, Y- hardened surface gear, Z- medium hard surface gear, K- output shaft is hollow shaft type.

Nominal center distance, expressed in actual figures, is mm.

The transmission ratio is expressed by nominal transmission ratio.

The assembly type shall be expressed in figures I, II, III and IV of Rome.

The rotation direction of the input shaft: in the direction of the input shaft, the S is clockwise, and the N is counterclockwise
