Compact drive | Series 045

Compact drive | Series 045

The Ortlinghaus compact drive from the series 045 and 046 is a ready-to-install drive unit consisting of a clutch-brake unit, a flywheel and a gearbox. This drive unit is used in metal-forming machinery such as eccentric presses in which the work capacity of the machine is derived from a flywheel. In comparison to spur gearing, the planetary gears used in the compact drives save installation space and have smaller rotating masses. High rotational speeds make it possible to keep the size of the flywheels to a minimum and, when used with Ortlinghaus clutch-brake unit, results in compact drive units with a broad power spectrum. The individual components (clutch-brake unit, flywheel with bearings and planetary gearing with output hub) are matched to each other in order to suit the characteristics of the machine in a space-saving assembly. These series have proven themselves in thousands of metal-forming machines over the years.

Two different compact drive designs can be used:

  • Pneumatically actuated single-plate clutch-brake unit (dry-running) for machines which mainly work in continuous operation.
  • Hydraulically actuated clutch-brake units (wet-running). These virtually wear-free, low-maintenance units are particularly well suited for medium and large presses which also work in single-stroke mode.

Main drive locking clutch | Series 055

Main drive locking clutch | Series 055

According to DIN EN 692, the relevant safety standards for press engineering, a mechanical restraining device must be present in mechanical presses for repair work and work between the two halves of the tool. The Ortlinghaus linear motion lock from the series 055 is an approved restraining device according to the German employers’ liability insurance association. The linear motion lock is used to positively lock a shaft to the fixed housing of a clutch so that the shaft cannot rotate. This is particularly desirable for presses to ensure that the press ram will not move in an uncontrolled or unintended manner during servicing or maintenance work between the two halves of the die. 

The Ortlinghaus ram locking mechanism enables a variable locking of the press ram in any position, with a short actuating time of about three seconds. The linear motion lock is matched to and integrated into the machine’s drivetrain. It is engaged or disengaged hydraulically. The state of the ram locking mechanism actuated by oil pressure, either locked or unlocked, is detected using inductive travel sensors and transmitted to the machine control unit.

Torque:
11,000 - 100,000 Nm
Outside diameter:
480 - 900 mm
Bore diameter:
120 - 260 mm
Length:
195 - 325 mm

Rotary inlet | Series 086/087

Rotary inlet | Series 086/087

Ortlinghaus has been manufacturing single and multi-channel rotary inlets for several decades and these are frequently supplied as accessories for air and oil actuated and also for oil cooled clutches. These tried and tested machine components for the feeding of air, pressurised oil and cooling oil into rotating shafts are standard products and are not only for use in conjunction with clutches. In addition to this Ortlinghaus also develops and manufacturers rotary inlets to customers own requirementswhich cannot be met from standard products listed in the catalogue. It is thus possible for example to manufacture rotary inlets with up to eight channels with the channels being able to carry different media (air / oil; air / water).

Hydraulical clutch-brake unit | Series 123

Hydraulical clutch-brake unit | Series 123

The hydraulically actuated clutch-brake units from the series 123 work exclusively with wet-running, oil-cooled plates with friction pairing steel/sinter. 

The advantages of having a multi-plate construction and oil-cooled friction pairing steel/high-performance sinter in addition to actuation with pressure oil at 60 bar are seen in the product’s extraordinarily compact design and high operating efficiency. The series offer high torque, low moment of inertia and high switching speeds with a minimal need for maintenance.  Model series 123 represent a good alternative to dry-running combinations. They operate in sealed housings which prevent leakage and keep switching noise to a minimum.

With these benefits, the clutch-brake units are suitable for a broad range of applications in press, shear press, and large press engineering as well as in embossing presses and drawing presses. 

The series was designed and constructed according to international safety regulations and approved by the German employers’ liability insurance association.

Torque:
3,000 - 630,000 Nm
Rotations per minute:
350 - 1,700 min-1
Outside diameter:
199 - 1,180 mm
Bore diameter:
58 - 375 mm
Length:
135 - 650 mm
