Overview

This product is a hard street cylindrical gear reducer produced according to the national standard JB/T8853-2001.

This product is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical and other fields.

The range of the reducer is as follows:

1. The speed of the high speed shaft is not more than 1500 rpm.

2. The gear drive peripheral speed is not more than 20 m / s.

3. Working environment temperature is -40~45°C, if it is lower than 0deg; C before the start of the lubricating oil should be preheated to 0 or deg; above, the reducer can be used in both forward and reverse directions.

First, characteristics

1. The gear is made of high-strength low-carbon alloy steel by carburizing and quenching. The hardness of the tooth surface is up to HRC58-62. The gears are ground grinding technology with high precision and good contact.

2. High transmission efficiency: single stage is greater than 96.5%, double level is greater than 93%, and third level is greater than 90%.

3. Smooth operation and low noise.

4. Small size, light weight, long service life and poor carrying capacity.

5. Easy to disassemble. Easy to install.

Second, the reducer model, specifications and their representation methods

1. Models include: ZDY single-stage cylindrical gear reducer. ZLY two-stage cylindrical gear reducer, ZSY three-stage cylindrical gear reducer • ZFY four-stage cylindrical gear reducer.

2. Specifications:

Two levels: 112, 125, 140, 160. 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560, 630, 710;

Level 3: 160. 180. 200, 224, 250, 280, 315, 355, 400, 450, 500. 560, 630. 710-

Level 4: 180, 200. 225, 250, 280, 320. 360, 400, 450, 500. 560, 630. 710. 800

3. Example of representation method:

★ means single level, L means two levels, S means three levels, F means four levels, Y means hard tooth gears

4. Steering regulations: The speed reducer with backstop can only be operated in one direction. The steering regulation is: facing the output shaft, the output shaft runs clockwise to S and counterclockwise to N.
