ZDY, ZLY, ZSY series hardened cylindrical gear reducer

Product overview

ZDY series gear reducer is a hard-toothed cylindrical gear reducer produced in accordance with the national professional standard JB/T8853. It has the advantages of small size, light weight, high carrying capacity, long life, high efficiency and low noise. It is an ideal deceleration transmission device, with the international level in the 1980s; it is widely used in metallurgy, mining, petrochemical, energy, transportation, cement, construction and light industry industries.

Conditions of use

The ambient temperature is -40~+45℃. If it is below 0℃, the lubricating oil needs to be preheated to above 0℃ before starting. The high-speed shaft speed is not greater than 1500r/min.;

The circular speed of gear transmission is not greater than 20m/s.

Product features

This series of reducers has been optimized for design.The gears are made of high-quality alloy steel. After forging, tooth making, and strict heat treatment, THE gears ARE ground by the Swiss REISHAUER gear grinding machine, and the accuracy can reach GB/T10095-88 standard level 5.

Wide speed ratio range: nominal speed ratio single-stage 125 to 56. two-stage 63 to 20. three-stage 224 to 100

High mechanical transmission efficiency: single stage is greater than 96:5%, two stages are greater than 93%, and three stages are greater than 90%

The reducer can be used for operation in both positive and negative directions. When the user has one-way operation and reverse braking requirements for the reducer, a backstop can be configured at the high-speed shaft end.

Smooth operation and low noise

Small size, light weight, long service life and high carrying capacity

Easy to disassemble, easy to maintain, and easy to install.
