1)Descriptions of Transmission Gear Shaft
The transmission gear shaft is an integrated transmission component where the gear tooth profile is directly machined onto the shaft body. According to the tooth profile, it can be classified into various types such as straight teeth, helical teeth, and herringbone teeth. The structural design of this component needs to comprehensively consider key parameters such as transmission ratio, torque, and rotational speed.
2)Advantages of Transmission Gear Shaft
a)Transmission efficiency is as high as 98-99%
b)Can withstand torque ranging from 1000 to 10,000 N·m.
c)The maximum rotational speed can reach up to 5000 - 10000 rpm.
d)The service life is extended by 30-50% compared with the separate design.
3)Applications of Transmission Gear Shaft
a)Rail transit drive system
b)Marine propulsion device
c)Power transmission of mining machinery
d)Aerospace and aeronautical transmission systems
