Logan self-adjusting Bell Housing PTO clutches have been standard equipment on all Oshkosh H-Series Blowers manufactured since 2005. Hundreds of Logan units are in the field, operating at a high level of excellence and readiness for major
A major harbor tug operator in the US had a need to up-grade some of it’s old Detroit Diesel driven Gensets. This operator has the hydraulic requirements for the boat and deck winches provided by two hydraulic pumps mounted on the front of two redundant Gensets.
To develop a unit that can go through an oil pipeline that is capable of doing measurements and still be strong enough to carry a cable through the pipe-line. Besides the pipeline being limited in space there are sometimes small obstructions to past through larger welds and dirt in spots. The customer solution was to build a Robot to do this work. Inside the robot there would be an electrical motor connected to a gearbox. That gearbox is connected to 2 axles. On each axle there are 2 clutches (4 clutches in total) and when there is an obstruction in the line there can be a peak load on one of the axles. A second later the other axle will help and the torque will be divided on each axle The peak load is only for a short moment, usually less than 5 seconds to pass the obstruction. If longer the electrical power drops in half to a safety mode. This means the torque to the clutch or the unit will never be above specifications. The start and stop of the unit is always without load so a clutch that does not slip is required.
A clutch needed to be supplied that was small enough to fit in the required envelope and still meet the torque requirements of the customer. A Logan PTO direct drive clutch would be a first choice but due to space limitations there was not a standard unit small enough to fit that would have the required torque. Logan then moved to a P-style clutch. The clutch is self-contained but not enclosed with a separate drive cup. Working with
