Plastic and Rubber Extruder Speed Reducer

Plastic and Rubber Extruder Speed Reducer (ZLYJ112 ZLYJ630): I. Introduction ZLYJ reducers are a kind of high-precision rigid gear assembly specially designed for the single-screw plastic/rubber extruder. Taking the JB/T 8853-2001 Cylindrical Gear Reducer as a reference for design, the products applies the high-strength low-carbon alloy steel for gears and gear shaft, with tooth flank carbureted, quenched and ground, to meet the gear precision at Level 6 (GB/T 10095) and hardness of tooth flank HRC54 62. A huge thrust bearing is mounted on the front of the output shaft to bear the thrust from the screw. II.Applicable Scope 1. The input rotation of prime mover shall be no less than 1500rpm. 2. The peripheral speed of gear drive shall be no less than 20m/s. 3. The working ambient temperature shall be within -40°C 45°C. Preheat the lubricating oil to above 0°C or choose the low temperature lubricating oil when the ambient temperature is below 0°C. Rotation is available both forwards and backwards. However, the high-speed shaft of some types of reducers has a single-way oil pump directing as defaulted to the output shaft which rotates clockwise. III. Speed Reducer Type a.
