What is hypoid axle?

Hypoid gearboxes are a type of spiral bevel gearbox, with the difference that hypoid gears have axes that are non-intersecting and not parallel. This provides more contact area and better tooth strength, which allows more torque to be transmitted and high gear ratios (up to 200:1) to be used.

What is the reason for using hypoid gears in the rear axle?

The hypoid gearset redirects rotation and torque and provides the final reduction at the drive axle. The advantage of this concept is the lower torque in the complex shift or automatic transmission and the high torque only at the ring gear at the drive axle.

What case is hypoid gear used in?

A Hypoid gear is used when the included angle is square and distance between axes are relatively small. The hypoid gear is viewed as an intermediate between a bevel gear and a worm gear machine.

What is hypoid oil used for?

Commonly found in axle differentials, hypoid gears are used to transmit power from the driveline to the axle shafts. They are basically spiral bevel gears, where the pinion engages below the centerline of the ring gear. This lowers the driveshaft away from the bottom of the vehicle.

Is Penrite gear oil hypoid?

GEAR OIL: Penrite’s range of premium mineral automotive gear oils are manufactured with modern extreme pressure additives and friction modifiers. This new formulation allows the one range of gear oil to be used in both limited slip and hypoid type differentials, eliminating the need for multiple products.

Is hypoid the same as WORM drive?

A hypoid gear has a 25:1 ratio range. A hypoid gear set, in this ratio range, is approximately 90% efficient per stage. Worm gears (Figure 4) consist of a non-intersecting shaft with a spiral thread that engages with and drives a toothed wheel. Worm gears are typically comprised of a bronze wheel and a steel worm.

Is hypoid gear oil the same as gl5?

GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.
