Designed to fit into high-torque applications where space is restricted, and featuring either a 1.25inch (31.75mm) bore hollow shaft or a 1.25inch diameter solid shaft in u-shaped or s-shaped configurations, Bison Gear & Engineering Corp is introducing its new FlexTorq 762 series hollow shaft offset DC gearmotors. Driven by 1/20, 1/4 or 1/2 HP (37, 186 or 373W) permanent-magnet 90V DC variable-speed motors, the FlexTorq 762 series is available in nine standard off-the-shelf models from Bison Gear and its distribution partners.
Todd Lucich, Bison Gear vice president for sales, says: "With over 1800 in-lbs (204Nm) of output torque, these new FlexTorq gearmotors are a solid value and a more energy-efficient alternative to large, expensive right-angle worm drives. This is a robust, flexible design that is ideal for conveyors, gate operators, machine tools, and foodservice equipment."
Fixed output speeds on the standard FlexTorq units range from 1.2-65rpm and Bison can provide matched variable-speed drives for the PMDC gearmotors. As part of its Robusticity design philosophy, Bison's pinion gears are integral to the motor shaft. Carbide cutting tools are used to hob the pinion teeth on automated hobbers. The pinions are then heat treated in a carbonitriding process that offers a hardened, wear-resistant surface. Bearing and gear life are maximised with oil bath lubrication, rather than grease.
FlexTorq gearmotors are manufactured in Bison Gear's Chicago facility to high quality standards in order to ensure a short supply chain and reliable, long-life operation. In addition, Bison's Innopreneurial application and design engineering capabilities to customise standard models to meet specific OEM needs are readily available.
