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 22):
A method for the installation of a driving system as defined in  claim 1  on the snow removal device, the method comprising the steps of:\n rotatably mounting on the frame or the auger housing the at least one driving gear adapted to be rotatably supported by the frame or the auger housing; \n mounting the at least one output gear adapted to be mounted on the shaft element of the at least one auger; \n installing the roller chain to link the at least one driving gear and the at least one output gear; \n installing the at least one means for the tensioning the roller chain; \n removably securing the first guard to the first lateral wall to form with the first lateral wall the first casing to prevent snow or debris contained in the auger housing to contact said first portion; \n removably securing to the frame the second guard to cover the second portion and to prevent snow or debris present around the snow removing device to contact the said second portion; and \n optionally providing a third opening in the auger housing; \n a first portion of the driving system for driving the auger being positioned within the auger housing and a second portion of the driving system for driving the auger being positioned outside the auger housing, the roller chain being adapted to be moved across the third opening of the auger housing.
