Tandler hypoid gearboxes have a solid shaft as standard. Optionally available with hollow shaft with keyway. Thanks to the single-stage design with ratios up to 15: 1, this gearbox has a low tooth backlash and very high transmission accuracy. The input shaft of the Tandler hypoid gearbox has a two-part coupling for direct connection to any desired motor.

Hypoid gearbox


Tandler (represented by GBS Machining Services) introduces with the hypoid gearbox a total concept for constructions with limited installation space, or for situations where a single-stage gearbox with high transmission is required.

Hypoid gears are special bevel gears, where the two shafts intersect. The shafts are shifted, creating a conical torque. The advantage of this is that a transmission of 15: 1 can be realized with one set of gears. Due to the higher forces, a special bearing is necessary.


Hypoid gears are special bevel gears where the center lines of the gears intersect. They are used in cars and forklift trucks, for example, to transmit the rotation from the drive shaft to the rear axle, thus driving the wheels. Due to this principle, the teeth are always spiral.

Hypoid gears are special bevel gears where the center lines of the gears intersect. They are used in cars and forklift trucks, for example, to transmit the rotation from the drive shaft to the rear axle, thus driving the wheels. Due to this principle, the teeth are always spiral.


A hypoid is a type of bevel gear whose shaft does not intersect with the meshing gear's shaft. The shape of a hypoid gear revolved to a hyperboloid (that is, the pitch surface of the hypoid gear in hyperbolic plane), while the helical bevel gear is usually conical. The hypoid gear places the pinion gear off-axis towards the ring gear (crown gear) making the pinion gear larger in diameter and more contact area. In hypoid gear design, the pinion and gear are almost always on opposite sides, and the helix angle of the pinion gear is usually greater than that of the gear. The hypoid gear is then a diameter larger than an equivalent bevel pinion.

A hypoid gear comprises a number of sliders and can be thought of as being half way between a straight cut material and a worm gear. Special gear oils required for hypoid gears because the sliding action requires effective lubrication under extreme pressure between the teeth.

Hypoid gears are used in drive technology that is more efficient than conventional worm gearing. They are considerably stronger in that any load is transported simultaneously through several tines. In contrast, bevel gears are loaded one tooth at a time. The multiple contacts of hypoid gears, with proper lubrication, can be nearly silent, as well.

helix angle


helix angle of hypoid gears

The helix angle in a helical bevel gear is the angle between the tooth tracks and an element of the field cone, and corresponds to the helix angle of helical gearing. Unless otherwise stated, the term helix angle is understood to mean the mean helix angle.

• Helix angle means the specific designation for the helical angle of the cone mean distance in a bevel gear.

• Outer helix angle is the helix angle of a bevel gear at the outer cone spacing.

• Inner helix angle is the helix angle of a bevel gear at the inner cone distance.

Hypoid gears

Hypoid gears are special bevel gears where the two shafts intersect. They are used in various Cars to connect the Drive Shaft to the Rear Axle.

What is a hypoid gear?

A hypoid gear is a bevel gear with an axis that does not intersect with the axis of the meshing gear or pinion. Its primary application is in the differential drive of a wheeled vehicle, where the drive shaft must be at right angles to the wheels. The helical teeth in this gear produce less vibration than a gear with straight or straight teeth. Hypoid gears are manufactured in pairs and must be replaced in pairs.

A right hypoid gear is one where the outer half of the teeth tilt in a clockwise direction when looking at the plane of the gear. Likewise, a left has the outer half of its teeth counterclockwise. The gear and its pinion usually have opposite dexterity. This type of gear can also be classified according to its helix angle - the angle between an element of the pitch cone and the tooth track.

A hypoid gear is in the form of a twisted hyperboloid, which means that the pitch surface forms a hyperbolic surface. The pinion is off-axis to the gear, also known as the crown gear. This allows the pinion to be larger than the hypoid gear, allowing the pinion to have more contact with the gear.

This type of gear is generally stronger and quieter than a regular bevel gear. It can also handle a higher reduction ratio. The teeth experience some sliding, which causes friction, which means that the gear needs special oils to lubricate it under very high pressure.

A greater offset in the hypoid gear increases its torque at the expense of efficiency. The most common use is in older rear-wheel drive vehicles, especially trucks, as the greater torque is most beneficial in larger vehicles. Modern car designers have often appreciated the greater efficiency of a common helical bevel gear.

A bevel gear needs to be much larger to deliver the same torque as a hypoid gear. This generally means that a bevel gear transmission has less ground clearance and produces a larger bulge in the floor of passenger cars. It is normally not practical to replace a hypoid gear with a more efficient bevel gear.
