A VARIABLE SPEED DRIVE |
摘要 |
A variable speed drive comprising two drives A and B, an output drive wheel (62) and an endless, extendible member (66) that is driven by the drive A an d B and extends round and rotates the output drive wheel (62). The drives A an d B are operable to move the endless member (66) around an endless path at a first speed at a first driving position and at a second speed at a second position. This causes local expansion or contraction of the endless member (66) round the output drive wheel (62) and so varies its speed.
