Low speed, high torque hydraulic motors - 2

Hydraulic Motors » » High power density - high power level considering the relatively small size. Axial piston motors are used in restricted space of precision cylindrical forgery machines to control the working hub onforgery tools. The strongest RM5000 radial piston motor can move weights of 100 tonnes in steelworks transport carts. » Jerk-free start up. Ideal in the operation of fire engine turntable ladders or fork-lift trucks which need to position heavy loads safely and quickly, often at extreme lifting heights. » Low operating noise of these hydraulic motors make them particularly...

AE series » Axial piston motors » Type AE3 - AE45 displacement 3 - 45 cm3/rev operating pressure 210 bar speed up to 3000 rpm torque 34 - 134 Nm Design modifications in the flow control inside the motor as well as in the arrangement of the pistons have led to significant improvement of the constancy of the rotational speed. In addition, the speed range was clearly extended downwards. For the standard motor which is already precise in competitive comparison, the ability to run is ensured for a minimum speed of 5 min-1. The high precision motor can achieve speeds of significantly less than...

Sectional drawing / description of function The force is transmitted from the piston (14) to the connecting rod (14.1) via cylindrical, pressure lubricated reciprocating bearing. A special design feature is the bending stress relieved gudgeon pin. This design is superior to a ball connection since friction losses are lower and all moving contact surfaces have a constant velocity. Control Design: The oil flow to and from the cylinders is arranged through a flat faced distributor (4) which operates in the following manner: Control rings (6 & 15) are mounted on eccentric (38) over roller...
