However, hypoid gears are usually less efficient (90 to 95%) than a similar set of spiral bevel gears, which can have efficiency ratings up to 99%. The efficiency of hypoid gears decreases as the axis offset increases and special attention must be given to lubrication to prevent gear wear as a result of the sliding action of hypoid gear teeth.

Jun 08, · Hypoid gears are a type of spiral bevel gear that are used to transmit rotational power between two shafts at right angles. Their efficiency at transferring power is typically 95%, especially at high reductions and low speeds, while efficiency for worm gears varies between 40% and 85%. Greater efficiency means smaller motors can be used

Oct 30, · As the name suggests, a straight bevel gear has straight teeth like a spur gear that are cut along the axis on a cone. For this reason, it can be quite noisy as the teeth of the mating gears collide upon making contact. On the other hand, a spiral bevel gear has spiral teeth that are cut in a spiral curve across the pitch cone.

When the transmission ratio is less than 2, the hyperboloid driving gear is too large compared with the spiral bevel gear, occupying too much space. At this time, the spiral bevel gear transmission can be selected, because the spiral bevel gear transmission has a large differential available space. For medium ratios, both gear drives are available.
