Описание Особенности Высокая удельная мощность High torque density Energy efficient Flexible, many sizes, few mechanical interfaces Insensitive for shock loads Very low moment of inertia Small footprint (total occupied volume) Freewheeling possibility Through hole diameter 270 мм Tandem mounting possibilty High starting torque 4-quadrant operation Dynamic brake Constant torque throughout speed range Frequent start/stop capacity Описание продукта When it comes to production, everyone wants more. But these days there’s less of everything else: from available time to the energy and resources for the job. With the Hägglunds CBm direct drive from Bosch Rexroth, the equation is easier to solve. The Hägglunds CBm packs 50 % more torque into a motor that’s smaller and 50 % lighter than its predecessor. That gives it the world’s highest torque-to-weight ratio. Even so, it has all the advantages you’d expect from a direct drive. Full torque from zero, protection from shock loads and fourquadrant operation are part of the same small package. Put simply, the Hägglunds CBm does more with less – and lets you do the same. From industry to offshore, you can handle more work with less space, less energy and less weight on the driven shaft. That means greater productivity with a smaller footprint. And that’s an ingenious solution. Bosch Rexroth hydraulics technology is counted on worldwide to deliver outstanding performance in industrial and mobile applications. As the technology leader, we refine each system to incorporate the quality and capabilities you need to help maximize your system performance.

The cylinder block is mounted in fixed roller bearings in the housing. An even number of pistons are radially located in bores inside the cylinder block, and the distributor directs the incoming and outgoing oil to and from the working pistons. Each piston is working against a cam roller. When the hydraulic pressure is acting on the pistons, the cam rollers are pushed against the slope on the cam ring that is rigidly connected to the housing, thereby producing a torque. The cam rollers transfer the reaction force to the pistons which are guided in the cylinder block. Rotation therefore occurs, and the torque available is proportional to the pressure in the system. Oil main lines are connected to ports A1 and C1 in the connection block and drain lines to one of the D-ports in the motor housing. The motor is connected to the shaft of the driven machine through the hollow shaft of the cylinder block. The torque is transmitted by splines.
