Title: (EN) VARIABLE SPEED TRANSMISSION AND SYSTEM USING SAME
Abstract:
(EN) The system (1) comprises: a driver (3); a rotating load (5) configured to be driven into rotation by the driver (3); a controller (12), for controllably changing a rotation speed of the load (5); and a variable speed transmission (11), arranged between the driver (3) and the load (5). The variable speed transmission (11) comprises a speed summing gear arrangement (21) with a first input shaft (23), a second input shaft (25) and an output shaft (27). The output shaft (27) is drivingly coupled to the rotating load (5). The first input shaft (23) is drivingly coupled to the driver (3). A continuous variable transmission device (43; 143; 243; 343) is mechanically coupled to the driver (3) and to the second input shaft (25) of the speed summing gear arrangement (21). The continuous variable transmission device (43; 143; 243; 343) is functionally coupled to the controller (12).Fig.l
