Abstract:
A driving system for driving at least one auger of a snow removing device comprising at least one at least one self-adjusting chain tensioner. A first portion of the driving system is positioned within an auger housing and a second portion of the driving system is positioned outside the auger housing. The roller chain is adapted to move across a third opening provided in the auger housing. The first portion is covered by a front guard to prevent snow or debris contained in the auger housing to contact said first portion. The front guard is provided with an opening adapted to surround a portion of a shaft element of the auger with a play between periphery of the opening and the periphery of a corresponding portion the shaft element. The play is either small enough to prevent water and or debris to enter the first casing, or filled with a filling element and/or covered with a sealing element secured to the front guard or the corresponding portion of the shaft element of the at least one auger, to have the play small enough to prevent water and/or debris to enter the first casing. The second portion prevent snow or debris present around the snow removing device to contact the said second portion. A snow blower provided with the driving system, a kit comprising parts and/or components of the driving system, a method for assembling the driving system, and a method for manufacturing some components or parts of the driving system.

Claim (Index 1):
A driving system for driving at least one auger of a snow removing device, said snow removing device comprising:\n a frame an auger housing supported on the frame or being part of the frame, and comprising a first opening defining a front opening, a second opening defining a rear opening, a first lateral wall and a second lateral wall; an auger comprising a shaft element having opposite ends which are respectively rotatably supported by the first lateral wall and the second lateral wall; means adapted for attaching the frame to a vehicle; and the driving system for driving the at least one auger, said driving system for driving the at least one auger comprising\n at least one driving gear rotatably supported by the frame; \n at least one output gear mounted on the shaft element of the at least one auger, close one of the first lateral wall of the auger housing; \n a roller chain linking the at least one driving gear and the at least one output gear; and \n at least one means for tensioning the roller chain comprising at least one self-adjusting chain tensioner; \n wherein a first portion of the driving system for driving the at least one auger is positioned within the auger housing and a second portion of the driving system for driving the at least one auger is positioned outside the auger housing, wherein the roller chain is adapted to move across a third opening provided in the auger housing; wherein the first portion is covered by a front guard secured to the first lateral wall and forming with the first lateral wall a first casing adapted to prevent snow or debris contained in the auger housing to contact said first portion; wherein the front guard is provided with at least one opening adapted to surround a portion of the shaft element of the at least one auger with a play between periphery of the at least one opening and the periphery of a corresponding portion the corresponding shaft element, wherein the play is either small enough to prevent water and or debris to enter the first casing, or filled with a filling element and/or covered with a sealing element secured to the front guard or the corresponding portion of the shaft element of the at least one auger, to have the play small enough to prevent water and/or debris to enter the first casing; and wherein the second portion is covered by at least one rear guard forming a casing secured to the frame and/or the auger housing, and adapted to prevent snow or debris present around the snow removing device to contact the said second portion.
