Hydraulic Motors

Radial Piston Cam Curve Design

Multi Stroke Hydraulically Balanced motor

An even number of pistons work in radial bores in cylinder housing.

The symmetrical design allows forces to be balanced - radial forces oppose each other.

Cam roller is Hydrostatic bearing.

Roller bearing acting on the guide plate unloads the piston from side forces

Advantages of DHDs in various applications

A. Soft Start - extremely smooth start and stop. Load sharing on start up - excellent.

B. Fluid couplings and associate problems disappear -trimming/balancing of coupling not required, balancing of E.M. not required.

C. Excessive stretch of belt avoided due to soft start acceleration. Particularly valid on twin drive machines.

D. No alignment problems - simple installation, lining up of three components, fluid coupling, gearbox and motors avoided.

E. Replacing of drive is simple, i.e. friction coupling on shaft and torque arm - fluid coupling, top up of fluid of change a substantial down time is experienced.



F. Power unit can go anywhere - allows flexibility in positioning.

G. Variable speed - in maintenance mode allows inching of the belt forward and reverse directions for inspection - superb for belt positioning when slicing belt, etc.

H. Simple system - hydraulic components with "off the shelf" availability. Spares as simple compared to conventional drives.

I. Drive is silent compared to conventional system.

J. Stop/start logic and control is simple compared to conventional drive. i.e. easily alter ramp times compared to fluid controls.
