1511177219125 - Helical gear

Helical gears are one type of cylindrical gears with slanted tooth trace. Compared to spur gears, they have the larger contact ratio and excel in quietness and less vibration and able to transmit large force. A pair of helical gears has the same helix angle but the helix hand is opposite.

1. Type:1,1.25,1.5,2,2.5,3,4,5,6,8,10,12,16,20,25,32,40,50.

2. Standard: DIN; GB, GOST, AISI, etc.

3. Certification: ISO9001, Form E, Form A, CO

4.Report: Material Report; Hardness Report; UT/MT Report; Dimensions checking report; Mechanical Property Test Report

1511178328216 - Helical gear

Helical gears last longer and are ideal for high-load applications, since they have a higher amount of teeth in contact. Load is at all times distributed among several axes, which produces less wear. They can transfer motion and power both among parallel and straight-angle axes.
