摘要：Gear-changing device for altering the rotating speed of an output gear shaft (13) by the selective engagement of a sliding gearwheel (21) with the constituent gearwheels of a reducing gear arrangement (10) which comprises a number of gearwheels which are mounted on parallel shafts and are engaged with one another, the gear-changing device being composed of an arm (17) which can be pivoted about the output gear shaft (13), of a sliding shaft (19) which can be rotated and is mounted on the arm, of a sliding gearwheel (21) which can be made to engage with a selected constituent gearwheel of the reducing gear arrangement (10), of a coupling gearwheel (20) which is mounted on the sliding shaft (19) and is in engagement with an output gearwheel (11), of a lifting element (22) which supports the sliding gearwheel (21) from the bottom and from the top and can be vertically displaced to make the sliding gearwheel (21) adopt one of a number of predetermined positions, and of a vertical positioning device for guiding the lifting element (22) to a predetermined position and for setting the lifting element (22) in the said position. <IMAGE>
