Gear reducer is an external meshing involute helical cylindrical gear reducer produced according to the national professional standard ZBJ19004. Gear reducer is widely used in East China as a rotary mechanism for tower introduced crane machinery, and is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields.

1、 Product Introduction

Gear reducers are generally used for low-speed and high torque transmission equipment. Even ordinary reducers for electric motors have several pairs of gears with the same principle to achieve the desired reduction effect. The ratio of the number of teeth between the large and small gears is the transmission ratio. With the continuous development of the gearbox industry, more and more enterprises are using gearboxes.

1. The R series coaxial helical gear reducer is manufactured in accordance with international technical requirements and has high technological content

2. Space saving, reliable and durable, high overload capacity, power up to 132KW;

3. Low energy consumption, superior performance, and gearbox efficiency of over 95%;

4. Low vibration, low noise, and high energy efficiency;

5. Select high-quality forged steel materials, steel cast iron box body, and high-frequency heat treatment on the gear surface; 6. After precision machining to ensure shaft parallelism and positioning bearing requirements, the reducer of the helical gear transmission assembly is equipped with various types of motors, combined into electromechanical integration, fully ensuring the quality characteristics of product use.

2、 Scope of application

1. The high-speed axle rotation shall not exceed 1500 revolutions per minute.

2. The circumferential speed of gear transmission shall not exceed 20 meters per second.

3. The working environment temperature is -40-45 ℃. If it is below 0 ℃, the lubricating oil should be preheated to above 0 ℃ before starting.

4. Gear reducers can be used for operation in both forward and reverse directions.

3、 Machine features

1. The gears are made of high-strength low-carbon alloy steel through carburizing and quenching, with a tooth surface hardness of HRC58-62. The gears are all machined using CNC grinding technology, with high precision and good contact.

2. High transmission rate: single-stage greater than 96.5%, two-stage greater than 93%, three-stage greater than 90%.

3. Smooth operation and low noise.

4. Small size, light weight, long service life, and high load-bearing capacity.

5. Easy to disassemble and inspect, easy to install
