01 22 Explosion protected Hydraulic Motors RM250 - RM900 Series according to ATEX Directive 94/9/EC
an excellence in engineering www.jbj.co.uk/ .html hydraulic-motors These hydraulic motors have a high starting torque, ideal for instance, for safe operation of the heavy gates on the material lock in a nuclear power plant or to hand over the weighty coils in a rolling mill. Due to the low amount of revolving mass, the rotational direction can be quickly changed, a feature very important in many test benches; when performing vibration tests on motorcycle forks or when testing the adjustment of wing flaps on aircraft. The components can perform up to 50 rotational direction changes per second. An exact adherence to the specified rotational speed profile is of essential importance for many fields of application of hydraulic motors. Here is a new generation of motors, for which a significantly improved constancy of rotational speed is achieved compared to conventional motors. www.jbj.co.uk/hydraulicmotors.html » high starting torque » immediately reversible » total efficiency up to 96% » extremely low moment of inertia » low maintenance » full torque available over complete speed range » shaft end can be subjected to high radial and axial forces » only very few moving parts in the rotating group » instrument shaft may be fitted » low leakage-built in wear compensation » suitable for use with fire resistant fluids » no counterpressure necessary when operated as a motor » suitable for use as pumps with boosted system » eminently suitable for control systems » control of feed and discharge possible » may be operated in parallel » small ports are B.S.P. type G threads according to ISO 22811 » SAE Flange connection HYDRAULIC MOTORS low speed, high torque (LSHT) 01737 767493 info@jbj.co.uk www.jbj.co.uk - registered in England No: 1185469 - jbj Techniques Limited is ISO certificated, committed to international coordination & unification of industrial standards.

General Characteristics and Features Design: The radial piston hydraulic motor has been designed with a high load capacity. It is efficient, has a low moment of inertia, and is capable of very low speeds and has excellent reversing properties. The concept features make it extremely quiet, being suitable for servo control systems with facility to work either as a motor or pump in booth directions. Design and Operation Drive Motor Consists of a close grain, high strength, cast iron cylinder block. Eccentric crankshaft concept. Operating characteristics: Five radial piston/connecting rod assemblies (14) bear on the crankshaft (7) which is located by heavy duty tapered roller bearings. Crankshaft bearings (17 & 18): Pre-loaded to take the thrust in booth axial directions, ensures silent running and allows heavy radial and axial loading on the output shaft (e.g. gear drives). Connecting Rod (14.1): The computer optimated design is hydrostatically balanced on the crankshaft with sufficient leakage to ensure lubrication and cooling. Friction losses are reduced to a minimum and, stick slip action is avoided at low speeds. High starting torque and running torque combined with high speeds are important features of the design. Long service life is assured since con-rod slippers are unaffected by contamination and self adjustable. Noninflammable fluids have been used with success. Noise generation is also reduced by the cushioning effect of the hydrostatic bearing design. 9 1 21 29 3 7 25 10 24 11, 12 19 17 18 37 20 39 47, 50 42 8 23 52 26 27 38 40 22 14 31 32 4 15 35 36 43 45 49 6 46 51 44 48 RM 250X - RM 900X Sectional drawing / description of function www.jbj.co.uk/hydraulic-motors.html #DriveLineHarmony 1
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 bearings (27) and, together with the body (1) form two annular passages. When oil pressure is supplied to the motor, the crankshaft (7) and eccentric (38) rotate together, allowing the control rings (6 & 15) to open the inner and outer annular passages to the oil flow. Control rings (6 & 15) are axially loaded by means of wave springs (43) to maintain constant clearance across the face of the distributor block (4) under pressure. The eccentric (38) is also axially loaded by means of the hydraulic compensator (26) and spring (42). The design ensures low friction losses, self cleaning across the distributor face, immunity from the effects of contamination and a low leakage loss. The sinusoidal opening characteristics of the distributor results in smooth and quiet running at all speeds. A two way shuttle valve (35 & 36) ensures that the inner and outer annular spaces between control rings (6 & 15) are always at the higher pressure applied to the motor. Available Options: The range is comprehensive, and the following features can be provided: 1. Choice of shafts 2. Double shaft extension 3. Motor and brake combinations 4. Geared motors; gear motor and brake combinations 5. Tachometer and other measuring attachments 6. Couplings, flanges 7. Viton seals 8. Special models for HFB and HFC non-flammable fluids 9. Direct valve assembly possible 10. Connection SAE J 518 High pressure (Typ: A1) Special custom designs on application.

Design modifications of the flow control inside the motor, as well as in the arrangement of the pistons have led to a far more constant rotational speed with negligible fluctuations. 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 rev/min. This high precision motor can achieve speeds of significantly less than 1rev/min with a good constant speed in unregulated operation. The maximum speed is still up to 2,000 rev/min, depending on the motor size. AE series » KM series » available in a new High Precision version. Use as standard for stable speeds significantly less than 1rpm.

RM series » Radial piston motors Type RM80N - RM5000X 3 displacement 80 - 5278 cm /rev operating pressure 250 bar speed up to 800 rpm torque 288 - 19320 Nm The radial piston hydraulic motor has been designed with a high load capacity. It is efficient, has a low moment of inertia and is capable of very low speeds and has excellent reversing properties. The concept features make it extremely quiet, being suitable for servo control systems with facility to work either as a motor or pump in both directions. Drive Motor: consists of a close grain, high strength, cast iron cylinder block. Eccentric crankshaft concept. Operating characteristics: five radial piston/connecting rod assemblies bear on the crankshaft which is located by heavy duty tapered roller bearings. Crankshaft bearings: preloaded to take the thrust in both axial directions, ensuring silent running and allows heavy radial and axial loading on the output shaft (e.g. gear drives). Connecting rod: the computer optimized design is hydrostatically balanced on the crankshaft with sufficient leakage to ensure lubrication and cooling. Friction losses are reduced to a minimum and stick-slip action is avoided at low speeds. High starting torque and running torque combined with high speeds are important features of the design. Long service life is assured since con-rod slippers are unaffected by contamination and self-adjustable. Non-flammable fluids have been used with success. Noise generation is also reduced by the cushioning effect of the hydrostatic bearing design.
