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 speed 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.

I. Features

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.
