MOTION CONTROL: Ogura general purpose clutches are being used more frequently on a variety of mobile and light construction equipment. Clutches are available in 3 torque ranges of 100 lb-ft, 250 lb-ft, and 350 lb-ft. Clutches are made to mount on standard engine shafts of 1 inch, 1 1/8 inch, 1 ¼ inch and 1 7/16 inch and are normally suited for engines from 14hp to 35hp and speeds up to 4,000 RPM. Electric clutches are normally belt driven but models are available with universal mounts to accept coupling or universal joint flanges.
These clutches are used on a variety of outdoor power, farming and light construction equipment such as trenchers and mixers. They allow for the disconnection of a driving component such as a pump, fan or blade when not in use providing lower fuel consumption and increasing the driven components life. The other advantage with the electric clutch is the workers safety. Since both engagement and disengagement can be accomplished in fractions of a second, machinery can be fitted with operator presence controls or remote engagement switches to help prevent an injury that could be caused by accidental machine engagement.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
