Worm NMRV

For general industrial applications in engineering are widely used worm gears.

Depending on the accuracy of performance, design features (profile round, the number of thread starts, the number of stages, etc.), lubrication efficiency worm gear may reach 92-94%, while the worm gear designed for exceptional smoothness and quiet operation.

Worm motor - reducer PMRV differ upgraded universal housing allows for installation of the motor - reducer in any position. Worm-stage motor - PMRV series reducer is a modernized series, manufactured using injection molding technology. Combines high reliability and an affordable price. Thanks to standardized connection dimensions can serve as a replacement of defective motor - reducers other companies.

Worm gearboxes Lenker can dock into a pair with each other by using KIT-sets, allowing you to get the gear ratios up to 4000 and beyond. Often, to improve torque and gear ratio used compact parallel shaft gear, mounted between the engine and the worm gear.

The most important competitive advantage gearboxes Series PMRV:

  • compactness;
  • high efficiency;
  • low noise;
  • high specific power and torque transmitted;
  • resistance to alternating loads and frequent starts;
  • resistance to high radial loads on the output shaft;
  • increased operational durability - from 3 to 10 years;
  • gearbox commissioning under the full load, ie, without the running speed of the worm gear;
  • equipment forced cooling and lubrication systems;
  • diagnostic equipment and alarm systems (oil temperature gauge, oil quality monitoring device, vibration monitoring of bearings, etc.).
