At the National Manufacturing Week 2009, SEW Eurodrive , will launch W37 and W47 right-angle gear unit ranges, which are recent additions to their 7 series range of modular geared motor solutions. Featuring gear ratios of 3.2, the new W37 and W47 right-angle gearmotor ranges provide manufacturers with high output speeds and high levels of drive-train efficiency.
The W37 and W47 right-angle gearmotor ranges deliver torques from 70 to 110Nm and 100 to 180Nm respectively, making them suitable for a range of conveying applications. The W37 and W47 right-angle gearmotor ranges are energy-efficient and incorporate a two-stage gearing arrangement. The first stage comprises a helical gear arrangement, while the second stage incorporates SEW Eurodrive’s Spiroplan gearing configuration.
According to SEW Eurodrive, the W37 and W47 right-angle gearmotor ranges are suitable for the manufacturing sector. Across a number of manufacturing industry sectors, there is a trend of products getting smaller. This requires the modification of multi-conveyor production lines. By minimising the gap between each conveyor, small products are prevented from falling between them. One way to achieve this is to employ conveyors with small-diameter rollers. However, in order to maintain throughput, roller-speeds must be increased.
The W37 and W47 gearmotor ranges deliver the high-speed output required, and their right-angle configuration makes them suitable for mounting directly on the conveyor. Where conveyor gap-width is not an issue, the W37 and W47 gearmotor ranges can be incorporated into existing conveyor applications to increase throughput and maximise production rates.
Being part of SEW Eurodrive’s modular 7 series, the energy-efficient W37 and W47 gearmotor ranges provide users with gearbox/motor combinations customisable to suit manufacturing applications. Similar to all members of the 7 series family, the W37 and W47 gearmotor ranges are easily integrated with SEW Eurodrive’s direct-mounted asynchronous DR motors and synchronous servo CMP motor series, and are available with various mounting arrangements and shaft sizes.
The W37 and W47 gearmotor ranges’ hollow shaft mount housing features a compact, self-draining aseptic design free from crevices and contaminant trap-points, making them suitable for hygienic clean area manufacturing applications. The W37 and W47 right-angle gearmotor ranges are easily incorporated into SEW Eurodrive’s MOVIMOT decentralised drive system, which provides the flexibility, scalability and powerful connectivity required to support the manufacturing sector.
