g500-H helical gearboxes 3–14,000 N·m

Country: Germany · Model: g500-H

The g500-H is an in-line helical gearbox for 3–14 000 N·m, for motors of 0.12–55 kW. The input and output shafts lie on the same axis, so the drive is laid out along the machine axis. Versions are two-, three- and four-stage, with a ratio up to i=3240.

Description

The high permissible radial force on the output shaft, closely spaced ratio steps and low backlash make it possible to select the gearbox precisely for the load without excess margin. Shaft dimensions are standard for the market and flanges are standardised, so the gearbox is built into the machine and replaces gearboxes of other manufacturers without rework. It is supplied with m500 IE2/IE3 motors (0.12–55 kW, 3–14 000 N·m), MF at 120 Hz (0.55–22 kW, 4–3000 N·m), m550-U and m650-U of class IE5, m550-V of class IE6, MCS, MCA and m850 servo motors, and with the Smart Motor m300. Units with built-in i550/i650 motec inverters are available. They are controlled by i510/i550 cabinet, i550 protec and i550/i650 motec inverters. Selection is done in the EASY Product Finder and EASY System Designer.

How to choose

The torque on the output shaft determines the frame size, and the motor is selected within 0.12–55 kW. For the flat shaft-mounted version there is the g500-S, for the bevel version the g500-B. In the B.L.U. Line quick-delivery programme (0.37–2.2 kW, assembled in the USA) the g500-H is offered in frame sizes H100…H450 (100–450 N·m), alongside the g500-B110, B240, B450 and shaft-mounted g500-S. The lubricant is standard CLP 460 (460 mm²/s), positions M1–M6. The m550-H and m550-P IE2/IE3 motors have brakes of 4–23 N·m on AC 400–460 V or DC 205 V from the i550 motec.
