Hägglunds hydraulic industrial and marine mo tor COMPACT is of the radial-pis ton type with a ro ta ting
cylinder block/hollow shaft and a stationary housing. The cylinder block is mounted in fi xed rol ler bearings
in the housing. An even number of pis tons are radially located in bores in si de the cy lin der block, and the
valve plate directs the incoming and outgoing oil to and from the working pis tons. Each pis ton is working
against a cam roller.
When the hydraulic pressure is acting on the pis tons,
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 roll ers transfer
the reaction force to the pistons which are guided in
the cy lin der block. Ro ta tion therefore occurs, and
the torque available is pro por tio nal to the pressure
in the system.
Oil main lines are connected to ports A and C in
the connection block and drain lines to ports D1,
D2 or D3
in the motor housing.
The motor is connected to the shaft of the dri ven
machine through the hollow shaft of the cy lin der block.The torque is
transmitted by using a mechanical shrink disc, or alternatively by splines.
The symmetrical design of the motor has made it possible to design it as a two dis pla ce ment mo tor. This
means that two dif fe rent displacements and speeds can be obtained for a given fl ow. To get the 2-speed
function, a motor prepared for two speeds has to be ordered together with a 2-speed valve.
