1) Descriptions of Transmission Gear Shaft
In mechanical transmission systems, the gear shaft is a key
component that is responsible for efficiently transmitting power and adjusting rotational speed.
It has a compact structure and operates smoothly, and is suitable
for applications such as automotive gearboxes and industrial reducers.
It also enhances wear resistance through heat treatment processes.
2) Features of Transmission Gear Shaft
Compared with traditional transmission schemes:
a)Efficiency is improved by 5-8% (up to 95%+)
b)Volume is reduced by 30-40%
c)Bearing capacity is increased by 2-3 times
d)Operating noise is reduced by 15 decibels
3) Advantages of Transmission Gear Shaft
a)Precision solution: Guaranteed ±0.005mm machining tolerance by
German imported CNC gear grinding machine.
b)Maintenance solution: Standardized interface design, equipped with
intelligent lubrication reminder device.
c)Adaptation solution: Patent multi-directional connection structure,
capable of matching 98% of transmission system requirements.
