Japan develops out centering pulley to be able to be used at electromagnetism clutch and CVT

Slope east chemical industry (Bando Chemical Industries) be in " exhibition of energy-saving environmental protection 2007 " (on July 11, 2007 ～ 13 days, tokyo has bright international exhibition center) on, revealed but self-correcting and rotate the smooth belt that pulley contacts dynamical main transfer machinery of the position (graph) . This orgnaization also can regard the central line that is slide annulus and smooth belt to keep consistent " from centering pulley " . Book the commodity that applies to blower motivation main transfer machinery appears on the market inside year. In addition, still plan to apply at the domain such as electromagnetism clutch and CVT. The pulley construction that develops this is, peg installation is in go up by the runner shaft of motor drive, turn coming back is propped up by peg. Axis and stock to fold deserves to move component and bearing between turn coming back. Peg tilts on the way that installation uses power to turn coming back in smooth belt. Accordingly, turn coming back can tilt for the axis with peg center. Such, although smooth belt does the labyrinthian exercise of center of deviate turn coming back, also can realize those who pass turn coming back to tilt make smooth belt returns a center automatically from centering function. Built-in pulley groove waits through taking V all the time before this, the smooth zone that prevents to advance zigzag orbit deviate turn coming back. Accordingly, smooth belt can be come from lateral bear, bring about transmission efficiency to drop thereby. If use this technology, won't get lateral bear, can make transmission efficiency rises to be controlled to 98 ％ (when power input is 10kW) . The use that this company develops so the blower that 3 V take, its drive efficiency is 96 ％ about. If undertake turning over using from centering function to this, parallel is for instance mobile pulley, smooth belt can follow to this moves and move automatically. Come so, applicable is mixed at electromagnetism clutch the domain such as CVT. CNC Milling
