Nmrv Nrv Worm Gear Speed Reduction Gearbox Reducer

NMRV REDUCTION WORM GEARBOX
The NMRV 090 worm equipment motor is an angular drive in which the enter and output shafts are at appropriate angles to each and every other. A gearbox with a single gear stage gives equipment ratios of seven.five – 100. Electrical motor power: .37 – four kW. The push can be mounted in an arbitrary spatial position. Mounting alternatives: flange or feet.
The unified mounting dimensions supply the NMRV 090 gearmotor interchangeability with Varvel SRT 85, STM UMI 90, SITI MU90 models.
Parts supplies:
Circumstance – aluminum, flanges – aluminum, worm – metal, worm wheel crown – bronze.
Kind of lubricant: synthetic ISO VG 320.
Excess weight: 13 kg.
