KHK USA Inc., distributor of the market leading KHK brand of metric gears, highlights its extensive line of helical gears, manufactured by Kohara Gear Industry Co., of Japan.
KHK’s large selection of stock helical gears are suitable wherever high-speed rotation is required, including in machine tools, speed reducers and other industrial machinery.
Helical gears are cylindrical disks which have involute-shaped teeth cut into their face at a helix angle. By slanting the teeth, helical gears can obtain a large contact ratio and the gradual change to the contact surface load which give helical gears their characteristic of smooth transmission of rotation. Consequently, compared to spur gears, helical gears generate less vibration and noise and perform better in high-speed rotation and high-load applications.
Unique to KHK USA is the KHG Ground Helical Gear series. These gears feature exceptional strength and wear resistance due to being constructed of alloy steel and being hardened and ground finished. The unique feature of these gears is that they allow designs to be more compact because the KHG ground helical gears use a “transverse” module. This permits the assembly distance to be the same as spur gear pairs with the same module and number of teeth, and therefore KHG ground helical gears are often used as drop-in replacements for spur gears to achieve all of the advantages of helical gears without the need to change the rest of the gear train.
