Parallel Shaft Gearboxes
1. Product description
The gears of the parallel shaft gearboxes are made of high strength low carbon alloy steel by carburizing and quenching. The surface hardness of the gears is high. The gears are all grinded by NC grinding process, with high accuracy, good contact, high transmission efficiency, smooth operation and low noise. They are small in size, light in weight, long in service life and high in carrying capacity. They are easy to disassemble and inspect, and easy to install.


Technical parameters:
Nominal ratio:


2.Assembly form:
--Level 2-4 all have solid shaft, flat key with hollow shaft, shrinkage disk with hollow shaft
--Three output modes, six mounting surfaces and four mounting positions can be equipped with backstop to meet the needs of one-way rotation, and can be equipped with high power to achieve high load-carrying capacity.


3.Competitive Advantages:
 1).High transmission efficiency and strong bearing capacity
 2).Flexible proportioning and convenient combination
 3).Easy installation
 4).Reasonable cost
