Increasing efficiency for car seating manufacturer


SEW Eurodrive has supplied and installed a bespoke new drive system on a production line at a first tier supplier of car seating and interiors to the luxurious 4x4 SUV market


T


he old drives were installed within the body of the conveyor and were connected to the head shaft with chain drives. These units had to be replaced with a more powerful solution to cope with the heavier, higher specification seating of modern luxury cars. New, more robust drives would not fit into the body of the conveyor and so SEW Eurodrive’s engineers designed a completely new solution. Four new energy efficient helical bevel geared motors, with Movimot decen- tralised control, were installed with specially designed torque arm brackets for mounting the units to the floor, adjacent to the conveyor. SEW’s engineers specified Torqloc,


the company’s patented hollow shaft mounting system. Normal hollow shafts are made of carbon steel which can be prone to corrosion over time, eventually making the removal of the drive difficult. The Torqloc system requires no key in order to connect to the drive shaft and remains corrosion- free even after years of service. It con- tacts the solid shaft in only two places - at the support and torque bushings. The installation of the new drives has made maintenance much easier, as well as reducing the number of moving parts. They have been operat- ing trouble-free for over four months and, according to a spokesperson for the customer, “Since the installation down-time has been reduced by 30%,
