Apex Dynamics expands into hypoid gearboxes

Automotive Industry

Apex Dynamics has expanded into hypoid gearboxes with its BKM Series of high precision hypoid gearboxes which offer high torque, superior accuracy, excellent radial load capacity and low backlash in a design compatible with any motor.

Hypoid gearboxes are a type of spiral bevel gearbox. In contrast to traditional bevel gearboxes, they have non-intersecting axes, meaning they are not parallel, but rather are offset from one another. This provides them with hyperbolic rather than conical geometry.

Due to the tooth design, there is a greater contact area, meaning higher torques and gear ratios are possible, delivering greater precision. Hypoid gearboxes are compact and also offer smoother running properties, have quiet operation and can achieve lower backlash ratings than traditional bevel or worm type gearboxes. They tend to be used where speeds exceed 1000 rpm, or for lower speed applications that demand extreme smoothness or quietness.

Although hypoid gearboxes are currently a relatively small segment of the overall precision gear market, it is likely to grow faster than the general rate as a range of industries continue to see the benefits of the technology. This includes high-growth sectors such as robotics and automation. .

A range of industry sectors employ hypoid gearboxes in a variety of applications. Some of the key markets for hypoid gears are outlined below, along with the main benefits each industry derives from their use.

Hypoid gearboxes provide unmatched performance to the automotive industry when it comes to power transmission and are often used in rear-wheel-drive and all-wheel-drive systems to ensure efficient torque transfer between the engine and the drive wheels.
