Bevel gearboxes replace worm gears

摘要

Lenze GKR bevel geared motors are designed as replacements for worm geared motors and offer massive savings in energy costs. The extra purchase cost is paid back in only a few months of continuous running as the efficiency improves from 50-70% up to 96%. These geared motors are available for motor powers from 60W to 7.5kW with output torques up to 450Nm and ratios up to i = 76. The GKR bevel range actually contains two gear stages. The first stage is a helical gear with a small ratio.
