Delta Line adds three-stage option to GP42-S and GP56-T planetary gearboxes
Delta Line now offers an additional option to their popular GP42-S and GP56-T planetary gearboxes. Both of these gearboxes are now available with a 3-Stage option. Planetary gearboxes have the advantage of being compact with high efficiency, low backlash and provide a high torque-to-weight ratio, especially when compared to other types of gearboxes. The Delta […]
Gearmotors driving the timber industry
Rugged innovative gears and gearmotors along with other drive technologies rise to the challenge in demanding wood-processing applications. By Oscar Lopez • Service manager — industrial gearing | SEW Eurodrive Applications in the timber industry are varied and demanding — consisting of debarking, sawing, drilling, milling, and grinding operations. The machines used in these processes […]
New adopter-combined gearhead from Nidec-Shimpo
Nidec-Shimpo Corporation has added adopter-combined gear-head types to its FLEXWAVE series of precision control reducers currently on sale. Conventional FLEXWAVE reducers, which are intended to be installed in robots, have frequently been sold as individual or assembly components, and installing a FLEXWAVE reducer in a commercially available servo motor would require the user to prepare […]
How to get zero backlash out of gearing?
Gearmotors use gears to reduce speed, which makes more torque available. The kind of gears used in gearmotors have an impact on the available torque, but also on things like noise levels and accuracy. In fact, one of the more common sources of inaccuracy in gearmotors is due to gear backlash. So reducing the amount […]
What determines worm gear efficiency, and is it really that low?
Worm gears are often used for their ability to provide very high reduction ratios (and high torque multiplication) in a compact, single-stage design. But traditional thinking says that these benefits come at the expense of efficiency. Here, we’ll look at the factors that determine worm gear efficiency and how to get the benefits they provide […]
New mini planetary gearmotors for small stepper motors
Applied Motion Products’ new PH Series mini planetary gearmotors are used with small step motors in NEMA 8, 11, and 14 frame sizes. The small design of the gearheads allows them to be paired with small motors and doesn’t adversely affect the outside dimensions of the combined gearmotor. These gearmotors are used in applications where […]
New gearboxes for electric motors in mobile machines
As part of its new, extensive eLION platform for the electrification of mobile working machines, Bosch Rexroth has developed spur gearboxes which vehicle manufacturers can use to unlock the full potential of new electric motors. The 1-speed spur gearbox (eGFZ 9100) and the 2-speed shift gearbox (eGFZ 9200) are installed in the central section of […]
Leading motion-control and actuation options for robotics
Advanced robotics for industrial and consumer applications demand sophisticated power-dense motion components for joints and linkages that must run smoothly, often at high torque and relatively low speed. The challenge is compounded when the robotic application must also make precise moves. At the core of most leading robotic-actuator options are electric motors. That’s because motor-driven designs […]
Basics of wave and cycloidal gearing for robotics and servo designs
Many of today’s precision applications necessitate gears capable of dramatic speed reductions, power densities, and transmission accuracies. Leading choices in these designs include trochoidal and cycloidal gearing as well as gearsets relying on wave-inducing subcomponents having an elliptical or Reuleaux or other polygonal shape. Trochoidal and cycloidal gearing includes elements that rotate and trace curves around […]
