Gear Boxes

Bevel Gear Box

At KHK, we offer three types of bevel gear box, which are pre-lubricated and freely mountable in any direction, and they can be selected according to intended use and load torque.

Standard Miter Gears

Standard Bevel Gears

Standard Worm Gears

Screw gears, also sometimes called crossed helical gears, are helical gears used in motion transmission between non-intersecting shafts. The helical gears used in parallel shafts have the same helix angle but in the opposite directions. For shaft angles other than parallel, an arbitrary helix angle can be chosen, and, assuming no profile shift, the intersecting angle of the shafts is the sum of the respective helix angles. Helical gears have point contacts and have lower efficiency than parallel or perpendicular shaft gears and cannot transmit heavy loads.

Standard Stock Gears

Just as the name suggests, stock gears are defined as gears which are always stocked. When the gears of machines in operation break, the person in charge of the maintenance of the machines can immediately replace them if gears of the same shape are in stock at a suppliers base. Also, for the machine designers, when designing machines they can check the specifications of already designed stock gears and adopt stock gears as the gears to use when the specifications of said stock gears match the needs of the machine they are designing. In such cases there is no need for the machine designers to design new gears, and furthermore it is possible to procure the small amount of gears needed to produce a prototype of the machine quickly and affordably.
