Abstract
A belt assembly which, in operation, can be tensioned along a path, comprising a belt having a toothed surface and a back surface and one unit or a plurality of units fastened to the belt on the side of the back surface. In the area of the or each unit, parts of the belt are bent out of the path of the belt assembly in the direction of the unit. The unit comprises a retention element which is in engagement with the toothed surface of the bent belt parts. Further disclosed are units for use in the belt assembly according to the invention.
Claims26
A belt assembly for mounting under tension on a belt path, comprising:
- a toothed gear,
- a belt having a toothed surface for driving by the toothed gear and an oppositely located back surface, and
- at least one unit fastened to the belt on the side of the back surface, wherein, in the area of the at least one unit, parts of the belt are bent out of the path of the belt assembly in the direction of the unit, said unit including a contour against which the back surfaces of the bent belt parts abut and at least one retention element which is in engagement with the toothed surface of the bent belt parts, the retention element and the contour positioning the belt parts so that teeth of portions of the toothed belt on either side of the unit define a toothed profile extending over both belt portions and across the unit, a distance between teeth of one belt portion and teeth of the other belt portion across the unit being a whole multiple of a pitch of successive teeth of each belt portion.
A belt assembly for mounting along a belt path in tensioned condition, comprising a belt having a toothed surface and an oppositely located back surface and at least one unit fastened to the belt in a position on the side of the back surface,
- wherein, in the area of said unit, portions of the belt are bent out of the path of the belt assembly in the direction of the unit, and
- said unit comprises at least one retention element in engagement with the toothed surfaces of the bent belt portions, said unit having supporting contours against which the back surfaces of the bent belt portions abut, and having a connecting portion carrying said supporting contours in substantially fixed positions relative to each other and defining at least one passage for receiving said bent belt portions, said at least one retention element projecting from said connecting portion into said passage in a substantially fixed position relative to said support contours.
A unit for connection to portions of an elongated toothed belt having a tensioned belt path, comprising:
- oppositely arranged supporting contours for supporting portions of a toothed belt bent out of the belt path,
- at least one retention element located opposite at least one of said supporting contours and adapted for engagement with the toothed surfaces of the bent belt portions,
- and a connecting portion carrying said supporting contours in substantially fixed positions relative to each other and extending about at least one channel for receiving the bent belt portions, and said at least one retention element projecting from said connecting portion into said channel in a substantially fixed position relative to said support contours.
