Product Introduction

Application scope and advantages

This ZQ Series Cylindrical Gear Gearbox Speed Reducer is widely used in all kinds of lifting, transportation, mining machinery and other industrial machinery for deceleration. The linkage mode can be directly linked by coupling or flexible linkage of triangle belt. The machine has the advantages of strong versatility and interchangeability, simple maintenance, efficiency coefficient of 0.94, small starting resistance, flexible movement and so on.

Structure overview and main components

The structure of the machine is a two-stage three-axis cylindrical helical tooth horizontal division full seal. The lubricating oil is filled in the interior of the reducer, the oil baffle is provided on the drive shaft and the intermediate shaft, the rolling bearing is used in the fulcrum of each shaft, and the axial clearance can be adjusted by the internal adjustment ring. The upper part of the machine has a check cover, and the lower part has the oil marker pointer and the oil plug for discharging waste oil.

Gear and shaft are made of high quality carbon steel, and after tempering treatment, gear is made of high-grade cast steel, and after normalizing treatment, the box material is gray cast iron HT-200 and after aging treatment, gear according to 8 precision manufacturing of hobbing helical gear.

Main specification:

This series of reducer is divided into the following types according to the size, speed ratio and assembly type:

• According to the active shaft, passive shaft center distance divided into eight models :JZQ250, JZQ350, JZQ400, JZQ500, JZQ650, JZQ750, JZQ850, JZQ1000. (PM250, PM350, PM400, PM500, PM650, PM750, PM850, PM1000)
• According to the speed ratio size, each model is divided into the following nine speed ratios:48.57 40.17 31.50 23.34 20.49 15.75 12.64 10.35 8.23
