摘要:
A transmission (111) for a working machine including a drive transmission mechanism (123) and a working transmission mechanism (122) operated by swinging a shift lever (36) is provided. The drive transmission mechanism has a key-sliding transmission mechanism (138A) axially mounted on a drive shaft (78). The key-sliding transmission mechanism causes a selected one of a plurality of gears (139B) rotatably mounted on the drive shaft and the drive shaft to rotate together to transmit power to drive wheels (13, 14).

An auger snow-removing machine includes a forward rotation shaft and a reverse rotation shaft disposed on the same axis and aligned in a width direction of an auger housing within the auger housing, and a transmission (35) disposed inside the auger housing such that the forward rotation shaft and the reverse rotation shaft are rotated concurrently in opposite directions by a driving force transmitted from the transmission. A case (63) of the transmission is divided into a front case member (64) and a rear case member (65) at a position behind a reverse rotation drive shaft (73) extending in the width direction of the auger housing. The front case member has a first gear unit (61) ass4mbled therein, and the rear case member has a second gear unit (62) assembled therein. The first and second gear units are assembled together when the front and rear case members are assembled together.

An auger snow-removing machine (10) includes left and right forward rotation augers (41L, 41R) rotatable in a first direction (Ra) during snow removal and left and right reverse rotation augers (42L, 42R) rotatable in a second direction (Rb) opposite the first direction during the snow removal. The forward and reverse rotation augers are coaxially disposed in alignment in a width direction of an auger housing (21) within the housing. Distal ends (51a, 57a; 52a, 58a) of the left forward rotation auger and the right reverse rotation auger have phases set to substantially simultaneously reach a lowermost location when the forward and reverse rotation augers rotate. Distal ends (53a, 55a; 54a, 56a) of the right forward rotation auger and the left reverse rotation auger have phases set to substantially simultaneously reach the lowermost location when the forward and reverse rotation augers rotate.

An operating lever unit (30) for a walk-behind working machine includes an operating lever (50) pivotally disposed adjacent to a grip (18) of a handlebar (16a) for being gripped with a human operator together with the grip, a swing arm (70) pivotally disposed adjacent to the grip for operating an operated member of the walk-behind working machine, and a lock lever (60) pivotally mounted on the operating lever for operation by the human operator to releasably lock the swing arm in position relative to the operating lever. The lock lever includes a lock pin (65) adapted to be engaged with a part of the swing arm when the lock lever is operated by the human operator.

In an auger snow plow, right and left forward rotating augers (41, 41) and right and left backward rotating augers (42, 42) are disposed on a same axis and aligned in a width direction of an auger housing (21). A blower housing (22) is disposed at a rear portion of the auger housing and also positioned at a widthwise center of the auger housing. A blower (24) is disposed inside the blower housing. The right and left forward rotating augers (41, 41) are positioned at least in an entire range of a width (Wb) of the blower housing (22). The right and left backward rotating augers (42, 42) are separately positioned on both sides of the right and left forward rotating augers (41, 41) and positioned only at a more outer side than the width of the blower housing (22) in the width direction.

摘要:
A transmission (111) for working machines having a drive transmission mechanism (123) and a working transmission mechanism (122) which are operated by swinging a shift lever (36) is provided. The transmission has a drive shift member (157) for connecting the shift lever to the drive transmission mechanism and a working shift member (145) for connecting the shift lever to the working transmission mechanism. The shift lever (36) has a first protrusion (191) constantly engaging the drive shift member and a second protrusion (192) arranged to engage with or disengage from the working shift member. When the first protrusion engages the drive shift member with the second protrusion not engaged with the working shift member, only the drive transmission mechanism operates. When the first protrusion engages the drive shift member with the second protrusion also engaging the working shift member, both the drive transmission mechanism and the working transmission mechanism operate.
