Metric Helical Gears
KHK USA Inc., distributor of the market leading KHK® brand of metric gears, announces its extensive line of helical gears, manufactured to the highest quality standards 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.Two categories of KHK helical gears are available. Ground Helical Gears (KHG) feature exceptional strength and wear resistance that allow designs to be more compact. KHG ground helical gears use a "transverse" module. The assembly distance is 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.KHK also offers Helical Gears (SH) that feature larger contact ratios compared to stainless steel spur gears. SH helical gears.
