Double helical gears overcome the problem of axial thrust presented by single helical gears by using two sets of teeth . 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.
The teeth on helical gears are cut at an angle to the face of the gear.
When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement. This gradual engagement makes helical gears operate much more smoothly . Gears are a crucial part of many motors and machines. We have two different types of KHK helical gear products, one is a. KKHG gear type, and the other is a KSH gear type. Each type of gear has different module systems, pressure angle designations and helix angles.
Metric ground helical gears are available in alloy steel or mild steel material. Order our helical gears online.

They are designed to distribute pressure gradually along the whole tooth. Because of their tooth inclination, helical gears run smoother and quieter than other gears and are able to carry heavy loads efficiently. Spur gears and helical gears work identically to transfer power from one gear to another. But what are the strengths and weaknesses, and advantages and disadvantages of each design?
I think that is to demonstrate the axial load that developes as torque increases. We can help you with product identification. How to get your parts identified. See how we go from raw metal to .
Bevel- helical gear units. Energy efficiency was a priority when developing the ZAE bevel helical range of gear units. The modular design accepts servomotors and can alternatively be supplied with an input shaft option.
