The principle – the technology

All-round superiority: the omsHypoid bevel gear technology

A drive principle that keeps its promise – maximum efficiency with a minimum of backlash and extremely quiet operation. omsHypoid bevel gear units, similar to the differentials in automobiles, have high load capacities and arc-shaped teeth.
The tooth geometry is the crucial factor for quiet operation and low backlash. Developed using the GLEASON process, this geometry is implemented in powerful drive technology based on optimized calculation, manufacturing, grinding and testing.
The rolling and lateral sliding of the meshing teeth produces a perfect hydrodynamic lubricant film and ensures practically wear-free operation with an efficiency of η > 96%.

Building on this, the proprietary SYNTECTM toothing facilitates high gear ratios with a bevel gear without a downstream spur gear for ultra compact drives.
The omsHypoid bevel gear technology: An economic principle with a powerful drive

Uncompromising quality
– economic, convenient and reliable.

Whether in escalators or elevator drives – omsHypoid gears pay for themselves fast. All possible savings potentials, including compact space requirements, minimal maintenance and energy recovery are used to ensure economical operation.
Cost-effective and quiet: thanks to the remarkable quietness of operation and low noise emissions, people using your system will enjoy an extraordinarily comfortable ride.
And all this with quality you can rely on:
omsHypoid gears are proving themselves on a daily basis in over 100,000 escalators and elevator systems - even under the toughest conditions.

    The idea

    Intelligent solutions at sensible prices

    The modular principle makes this possible. OMS Antriebstechnik offers complete drive solutions with perfectly coordinated components from a single source. Thanks to the modular system, the drives of the omsHypodrive series meet nearly any utilization and application requirements you may have. Thus, for example, controlled drives with particularly low backlash are used in elevators with constantly changing directions of rotation, while the drives for subway escalators are designed especially for long-term continuous operation.
    The experienced designers at OMS Antriebstechnik work closely with the system engineering specialists to adapt omsHypodrives drives optimally to elevator and escalator architecture.
    This collaboration ensures the best possible configuration of the drives, which is essential to the durability and safety of the entire system.
