Cylindrical Gear Speed Reducer

Hard tooth surface cylindrical gear speed reducer mainly includes parallel shaft series and vertical shaft series. Parallel shaft reducer is in accordance with national standards (JB/T8853-200). 1) Production, product optimization design. It has advanced international level in the 1980s. It mainly includes four series: ZDY (single stage), ZLY (double stage), ZSY (three stage) and ZFY (four stage). The vertical shaft reducer is produced according to the national standard ("B/T9002-1999). It is used for transmission devices arranged vertically between input and output shafts. It mainly includes three series: DBY, DCY and DFY.

Cylindrical Gear Speed Reducer

1. Product description

Cylindrical gear speed reducer is a power transmission mechanism, the gear speed converter, the motor rotation number reduction to rotation number, and get a larger torque device. Cylindrical gear reducer is a relatively sophisticated machinery, the use of its purpose is to reduce the speed, increase the torque.


Technical parameters:

Transmission rate: Single-stage      1.25-6.3

                   Double-stage       6.3-20

                   Three-stage       22.4-100


Output mode:

Hollow shaft、Hollow shaft with straight key、Hollow shaft with shrink disc

2. Performance characteristics

 (1).The main parameters such as center distance, nominal transmission ratio and so on are all optimized by design.

 (2).The gears are made of high quality alloy steel by carburizing and quenching. The hardness of the gear surface is 54 ~ 62HRC.

 (3).Small size, light weight, high accuracy, large bearing capacity, long life, high reliability, smooth transmission and low noise.

 (4).The transmission efficiency of each gear can reach 98%-99%.

 (5).Oil pool lubrication and natural cooling are usually used. When the thermal power can not be satisfied, the circulat

ing oil skid or fan can be used. Cooling coil cooling.


3. Application scope

 (1).The input speed is generally less than 1500r/min.

 (2).The circumferential speed of gear transmission is not more than 20mis.

 (3).Working environment -40℃~+50℃. If it is below 0℃, the lubricant should be preheated to above 0℃ before start-up. The reducer can be equipped with a backstop for running in both positive and negative directions.

 (4).It can be widely used in metallurgy, mining, chemical industry, building materials, lifting, transportation, textile, paper-making, instruments, plastics, rubber, construction machinery, energy and other industrial sectors.
