NMRV REDUCTION WORM GEARBOX
The NMRV 090 worm equipment motor is an angular travel in which the input and output shafts are at appropriate angles to each other. A gearbox with one equipment phase provides gear ratios of 7.5 – 100. Electrical motor electricity: .37 – 4 kW. The travel can be mounted in an arbitrary spatial place. Mounting alternatives: flange or toes.
The unified mounting dimensions give the NMRV 090 gearmotor interchangeability with Varvel SRT 85, STM UMI ninety, SITI MU90 models.
Components components:
Situation – aluminum, flanges – aluminum, worm – metal, worm wheel crown – bronze.
Sort of lubricant: synthetic ISO VG 320.
Fat: 13 kg.
