Bosch Rexroths GFT 45 T2/T3 offers a two- and three-stage planetary drive in one package.
Bosch Rexroth Corp.s Hydraulics Technology group is unveiling a number of products for the heavy equipment market. Drives, pumps, and development tools bring a variety of benefits to system designers.
Engineers in construction, agriculture and forestry who need to reduce speed and increase torque delivered by a hydraulic motor to drive a sprocket, drum, or wheel might want to check out the GFT 45 T2/T3. It combines both a two- and three-stage planetary drive in one compact package.
Its dual-ratio drive provides two stages for low-ratio, high-speed operation and the third stage can be engaged for high-ratio, low-speed operation. Offering shift-on-the-fly capability, it has a maximum intermittent output torque of 45,000 Newton-meters and maximum output speed of approximately 150 rpm. The drive can operate at high speeds without an external cooling circuit.
Hydraulics Technology worked with Bosch Automotive to develop the BODAS mobile electronic system, a software system designed for use in the harsh mobile machinery field. Its programming interface makes it easy to set up, while a building block software architecture design helps engineers configure application software modules for their requirements. The hardware side includes sensors such as the intelligent DSM speed sensor and PR2 pressure sensors as well as joysticks and a durable graphical display.
The G Series Pump can handle rotational speeds of up to 2800 rpm and can work with a broad range of hydraulic fluids, simplifying purchasing and inventory requirements for companies that now use multiple pumps. It comes in displacement sizes from 32 to 63cc, handling high pressures and operating at a broad range of speeds.
