1. Reducer introduction

ZLYJ series hard surface reducer is a high-precision hard-toothed belt thrust seat transmission component designed for plastic screw extruder. The product design adopts the technical specifications specified in JB/T8853-2001. It features high-strength alloy steel for gear and shaft parts. The gear is processed by carburizing, quenching and grinding. Gear accuracy is GB10095-88.6. Tooth surface hardness HRC54-62. An over-sized thrust bearing is arranged at the front end of the hollow output shaft to withstand the working axial force of the screw. The main standard parts such as bearings and oil seals are made of domestic high-quality products, and can also be equipped with imported products according to user needs. The whole machine has the characteristics of small volume, high carrying capacity, stable transmission, low noise and high efficiency. Product performance has reached the international advanced level.

 

1. The main parameters

Type: parallel axis and orthogonal axis

Transmission series: 2~3

Power range: 10~1,6000kW

Speed ratio: 6.3~11.2

Rated torque: 0.05~400kNm

 

1. Performance characteristics
2. The combination of the box and the thrust bearing counteracts the axial force, and the inferential bearing is arranged at the oil chamber of the reducer to improve the operational reliability.
3. Small adjustments can be used to adjust the center distance
4. High transmission power, can withstand high torque and axial force

 

1. Applicable conditions
2. The speed of the high speed shaft of the reducer is not more than 1500r/min.
3. Gear drive cylinder speed is not more than 20 m / s
4. The working environment temperature is -40~45°C. If it is lower than 0°C, the lubricating oil should be preheated to above 0°C before starting.
5. ZLYJ series hard surface reducer can be used in both forward and reverse directions, but some models have high-speed shaft with single-phase oil pump. The default direction is: facing the output shaft, the output shaft rotates clockwise.

1. Lubrication and cooling, heating

Gears and bearings are lubricated with oil pools and splashes. In addition to splash lubrication, ZLYJ series hard surface reducer and above bearings have been added to the oil pump lubrication system for forced circulation lubrication.

The lubricating oil grade is medium-grade pressure gear oil N220 or other high-quality skating oil with similar viscosity.

When the ambient temperature is lower than 0 °C, an electric heating pipe is added to the oil pool to preheat the lubricating oil.

When the ambient temperature is higher than 35 °C, our company performs heat balance calculation according to the temperature value provided by the user to determine whether to increase the cooling device.
