准双曲面齿轮相对于锥齿轮和蜗轮的另一个巨大优势是精度或以齿轮齿隙测量的精度。锥齿轮,尤其是螺旋锥齿轮,可以成套制造,非常,齿隙低至约 6 弧分。然而,大多数蜗杆和蜗轮传动装置在齿轮啮合中具有更大的齿隙,使其不适用于动力传输以外的许多应用。
准双曲面齿轮可以实现低至 3 弧分的背隙规格,使其比锥齿轮或蜗轮布置更。这种精度水平与许多其他既定优势相结合,使准双曲面齿轮超越了动力传输并渗透到运动控制市场。
准双曲面齿轮用途最广
准双曲面齿轮现在广泛用于自动化和运动控制应用。它们的性能特点使其成为低速和高速应用以及需要极高精度的高循环率应用的理想选择。准双曲面齿轮箱提供单级和两级布置,配备行星齿轮级,提供从 3:1 到 100:1 的广泛传动比。
精密行星齿轮箱多年来一直存在于运动控制行业。为了将直列行星布置转换为直角减速器,齿轮箱制造商采用了一组螺旋锥齿轮来实现 90 度转弯。在过去的几年里,多级直角行星齿轮箱内的这些锥齿轮组正在被准双曲面齿轮所取代,从而使齿轮箱更加紧凑、高效和。
大多数制造商都在这些准双曲面齿轮箱的输入端设计了电机法兰,以允许各种电机(包括公制和 NEMA 伺服电机)直接安装到齿轮箱外壳上。无论是用于单级直角齿轮箱还是与行星级结合使用,准双曲面齿轮在运动控制行业中的应用越来越广泛。

Another enormous advantage that hypoid gearing has over both bevel gears and worm gears is precision or accuracy measured in gear tooth backlash. Bevel gears, particularly spiral bevel gears, can be made in sets to be very accurate, down to about 6 arc minutes backlash. Most worm and worm wheel gearing, however, have far more backlash in the gear tooth mesh, making them unsuitable for many applications beyond power transmission.
Hypoid gears can achieve backlash specifications as low as 3 arc minutes, making them far more accurate than either bevel or worm gear arrangements. This level of precision, combined with the many other established advantages, has allowed hypoid gearing to go beyond power transmission and to penetrate the motion control market.
HYPOID GEARS HAVE THE LARGEST RANGE OF USES
Hypoid gears are now commonly used across a wide spectrum of automation and motion control applications. Their performance characteristics make them ideal for both low- and high-speed applications as well as high-cycle-rate applications that require extreme precision. Available in single- and two-stage arrangements, packaged with a planetary gear stage, hypoid gearboxes offer a wide range of ratios from 3:1 up to 100:1.
Precision planetary gearboxes have been present in the motion control industry for many years. In order to convert an inline planetary arrangement into a right-angle reducer, gearbox manufacturers incorporated a set of spiral bevel gears to make the 90-degree turn. In the past several years, these bevel gear sets inside multi-stage, right-angle planetary gearboxes are being replaced with hypoid gears, resulting in more compact, efficient, and precise gearboxes.
Most manufacturers have designed motor flanges on the input of these hypoid gearboxes to allow for a variety of motors, including metric and NEMA servo motors, to mount directly to the gearbox housing. Whether used in a single-stage right-angle gearbox or in conjunction with planetary stages, hypoid gears have a growing presence in the motion control industry.
