Abstract

PURPOSE: To automatically put a speed change gear to a low speed transmission position upon stopping of transmission to make succeeding operations of an operating machine smooth by providing the speed change gear with a mechanism responsive to stopping of transmission by an operational lever for displacing a pair of transmission pulley members from each other and a mechanism for urging a transmission belt to a required direction.
CONSTITUTION: A speed change gear 12 includes a drive pulley 13 mounted on an output shaft 9, an idle pulley 14, a pair of transmission pulley members 15a mounted on an output shaft 10 for relative displacement in the direction of the rotational axis thereof, a tension pulley 19 supported for rotation on an arm 18, and a transmission belt 17 extended around these pulleys. In this speed change gear 12, infinite variation of speed and stopping of transmission can be effected by operating a lever 11 to engage or disengage the tension pulley 19 with or from the transmission belt 17. The speed change gear 12 additionally includes a pulley member displacing operating mechanism wherein a tapered roller 20 is mounted on the arm 18 and is operable in response to an operation of the tension pulley 19 to a transmission stopping position to engage between the paired pulley members 15a to displace them from each other, and a mechanism for urging the belt 11 in a diametrically outward direction of the transmission pulley 15 by an urging force of the weight of the belt 17.
