Product Description

NMRV  REDUCTION WORM GEARBOX
NMRV 150 CZPT motor for general industrial use refers to angular type drives. The unit provides high output torque (up to 1760 N * m), withstands significant radial loads (up to 18 000 N). Robust cast iron body gear motor has a protective coating. Mounting options: feet / flange.
Additional options:

  • reactive rod for reactive torque compensation
  • outlet flange for securing to the frame
  • variator attachment for regulating the output shaft rotation speed
  • torque limiter

Materials parts:
Body – iron, flanges – iron, worm – steel crown worm wheel – bronze. 
Type of lubricant: synthetic ISO VG 220. 
Weight: 84 kg.

Type designation scheme

NMRV – 150 – 7.5 – 186.7 – 15 – B7

  • NMRV – CZPT motor
  • 150 – size (center distance, mm)
  • 7.5 – gear ratio
  • 186.7 – output shaft rotation speed, rpm
  • 15 – electric motor CZPT , kW
  • B7 – mounting position
