<p>PURPOSE:To enable speed convertors to follow a moment of inertia of a blower sufficiently by constituting to adopt a non-step conversion for one belt, while a fixed reduction ratio for others, and thus stabilizing and ballancing a transmission ability charged for each belt. CONSTITUTION:The first belt of a core unit 4 fitted with a rib is wound to an input shaft 1 being provided with a pully 10 with a conversion ratio of a driving side with a pair of a fixed and a sliding pullies and also to an end of an intermediate shaft 2 provided with a pulley 20 with a follower's conversion ratio constituted in a similar manner. The second belt composed of V belts 51, 52, 53, is wound being provided with a pulley 30 of a fixed speed ratio at another shaft end of the intermediate shaft 2 while a pully 40 of a fixed speed ratio to an output shaft 3. A contact position of pullies 10, 20 in a driving side and in the follower's side is changed by a control motor 60 and the first belt is driven as a non-step speed increasing and decreasing convertor, and the second belt as a fixed speed ratio reducer, thereby stabilizing the transmission power for each belt allowing them to follow a moment of inertia of a blower sufficiently.</p> |
