ZLYJ Hard-Toothed Surface Gearbox Speed Reducer

The ZLYJ series plastic single-screw extruder gearbox is a high-precision hard-toothed surface transmission component with thrust seat specially designed for plastic screw extruders, and it complies with the technical specification JB/T8853-2001. The gears and shaft parts are made of high-strength low-carbon alloy steel and processed through carburizing, quenching and gear grinding. The gear accuracy reaches grade 6 of GB10095-88, and the tooth surface hardness is HRC54-62. An oversized thrust bearing is configured at the front end of the hollow output shaft, which can withstand the axial force of the screw working.
