Advantages of Bevel Gears
Advantages of Bevel Gears

Spur Gear Advantages. They offer constant velocity ratio; Spur gears are highly reliable; Spur gears are simplest, hence easiest to design and manufacture; A spur gear is more efficient if you compare it with helical gear of same size; Spur gear teeth are parallel to its axis. Hence, spur gear train does not produce axial thrust.

Applications of Bevel Gears
Applications of Bevel Gears

Bevel gears are modified to serve in many different applications. Gears with different numbers of teeth on each gear half change the speed of rotation as they change the angle. This type of bevel gear helps automobiles and other vehicles turn corners.

The teeth on bevel gears can be straight, spiral or hypoid. Straight bevel gear teeth actually have the same problem as straight spur gear teeth -- as each tooth engages, it impacts the corresponding tooth all at once.

Hypoid bevel gears in a car differential This feature is used in many car differentials. The ring gear of the differential and the input pinion gear are both hypoid. This allows the input pinion to be mounted lower than the axis of the ring gear.

Disadvantages of Bevel Gears
Disadvantages of Bevel Gears

An obvious disadvantage of the helical gears is a resultant thrust along the axis of the gear, which needs to be accommodated by appropriate thrust bearings, and a greater degree of sliding friction between the meshing teeth, often addressed with additives in the lubricant. Thus we can say that helical gears cause losses due to the unique geometry along the axis of the helical gear’s shaft.

Helical Gearbox
Helical Gearbox

Helical Gears. Unlike Spur gears, Helical gears and Helical Gearbox both have the capacity to conduct a smooth operation. The teeth on a helical gear cut at an angle to the face of the gear.

Hypoid Gearboxes
Hypoid Gearboxes

Hypoid gearboxes are a type of spiral bevel gearbox, with the difference that hypoid gears have axes that are non-intersecting and not parallel. Hypoid gearboxes are a type of spiral bevel gearbox, with the difference that hypoid gears have axes that are non-intersecting and not parallel.
