Definitions

• the invention relates to a toothed-washer holder for door drives, in particular electromotive garage door operator, the door leaf of which is connected to a slide which is held in a guide rail which extends in the direction of drag of the door leaf between its closed and open positions and which engages with a toothed disk which is normally engaged in a form-fitting manner
• Drag link such as a roller chain, toothed belt, in particular a toothed belt, is connected, the toothed disk bolt or the hub of the toothed disk being accommodated on the two end faces thereof in bearing configurations of the holder
• Toothed lock washer holders for door drives have the task of positioning a lock washer - drive lock washer - in the guide rail of the drive
• Conventional toothed washer holders of this type have the disadvantage that the driving forces and the pretensioning forces of the drag link lead to a high perforation reveal pressure between the bearing designs and the toothed disk bolts or hub of the toothed washer penetrating them and thus lead to wear.
• the bearing designs can be designed as semicircular cylindrical shells in the groove bases a fork-shaped receiving device for the toothed disk can be formed, which is used in its entire thickness between its end boundary planes in the fork from the outside.
• the invention has for its object to provide a lock washer of the type in question, which has a much lower bearing pressure with simple assembly of the lock washer and drag link, especially in the form of a toothed belt, in which the drag link is guided in the engagement area with the lock washer and that can be easily and securely positioned in the guide rail
• the holder has, in addition to at least one of the bearing configurations, a belt guide formed in one piece therewith and that the bearing configurations on the toothed disc bolt or the hub are each supplied a distance from outside the toothed disc in the assembled state have between their mutually facing end faces, which is narrower than the distance between the end boundary planes of the toothed disk
• the toothed lock washer is constricted on both sides in the ring area between the pin or hub and the ring gear For this reason, bearing designs, in particular bearing collars, can be fed into the front of the toothed disc in the direction of the axis of rotation by penetrating the respective end boundary planes into the spaces set back from the planes by the constrictions and thus be more closely spaced with their facing end faces than the end boundary planes Bearing coils are formed axially longer, whereby the bearing pressure is distributed over a significantly larger bearing area than this with a fork-shaped mounting device with bearing half-shell formation in the fork groove base, between their Fork legs the lock washer is the case with the same overall extent in the axial direction
• the holder consists of two half-shells which can be fitted together in a fitting manner, each of which has a bearing collar as a bearing configuration, the bearing axes of which are aligned in the assembled state.
• the positioning of the bearing collars on the toothed-disk bolts or the toothed-disk hub is simplified and preferably dimensioned so that the bearing collars are mirror-symmetrical to the center of rotation in the assembled state, so that a uniform load distribution can be achieved on both bearings
• both half-shells can be provided with interlocking shapes.
• both half-shells are provided with a tongue and groove cross formation and can be fitted together to fit them.
• the half-shells are connected by means of a hinge arranged between them, that in the unfolded, not assembled state, the one half-shell as the lower part, on which the belt guide is formed, the insertion of one projecting end of the toothed-disk bolt or hub of the toothed disk together engaged toothed belt is accessible in the associated one bearing collar and that the folded-over other half-shell as upper part, approximately in the axial direction of the toothed disc, with its bearing collar receives the facing end of the toothed-disc bolt or the hub.
• the hinge is in particular formed as a film hinge in one piece between the half-shells and has a sufficient length that at least in the final phase enables the two half-shells to be joined vertically, so that the bearing collars can be used in their bearing position on the axis or hub of the toothed disc without tilting.
• This connectivity can be facilitated by the fact that Film hinge is formed on the narrow sides of the half-shells connecting these, which are the furthest from the bearing collars
• the toothed pulley holder with integrated toothed belt guide and in particular in one-piece design with bearing flanges and film hinge preferably consists of plastic and is in particular a plastic molded part
• FIG. 1 the toothed-disk holder glued on with an inserted toothed disk and toothed belt
• FIG. 2 shows a section through the toothed disk holder in the folded, fully assembled state within a guide rail indicated by dash-dotted lines,
• FIG. 3 shows a comparable section to illustrate the transfer from the opened to the closed, assembled state in different transfer positions
• the toothed-disk holder designated overall by 1 consists of an upper part 11 and a lower part 12, which are pivotally connected to one another on narrow sides facing one another by a film hinge 13 formed integrally thereon.
• the flat areas which come into contact with one another in the folded state - FIG. Feather cross formation into one another, the spring cross formation of which is formed on the upper part 11 and the groove-cross formation on the lower part 12 - FIG.
• the bearing collars 112 and 121 reach beyond the respectively assigned end-side boundary plane 22 of the toothed disk 2 towards each other, so that the distance between the mutually facing end faces of the bearing collars 112 and 121 is significantly smaller than the distance between the Frontal boundary planes 22 of the toothed disc 2 In this way, an axially correspondingly long design of the bearing cylinder surface of each of the bearing collars is obtained, on which the toothed disc bolt 21 engages with a correspondingly axially long bearing surface, so that the specific bearing pressure by the prestressing and de n Operation of the toothed belt 3 is small in accordance with the large area of the storage
• the toothed belt 3 In the engaging area between the toothed belt 3 and the toothed pulley 2, the toothed belt 3 is secured in its engaging position by a belt guide 122 which, as the wall area of the lower part 12, overlaps the width of the toothed disk 2 at a distance in which the toothed belt 3 in engagement can be accommodated during movement of the toothed belt 3 in the radial direction of the toothed pulley 2 away from it, the toothed belt 3 arrives at the belt guide 122, clearly before the tooth engagement between the toothed pulley 2 and the toothed belt 3 is left.
• a belt guide 122 which, as the wall area of the lower part 12, overlaps the width of the toothed disk 2 at a distance in which the toothed belt 3 in engagement can be accommodated during movement of the toothed belt 3 in the radial direction of the toothed pulley 2 away from it, the toothed belt 3 arrives at the belt guide 122, clearly before the tooth engagement between the toothed pulley
• the holder 1 In the collapsed position under the engagement of the tongue and groove cross connection 11 1 and 123, the holder 1 is secured in this position by means of two screws 4 and held at the same time, the wall of the guide rail 5 on which the toothed disc holder 1 together with toothed disc 2 and toothed belt 3rd to be arranged, also reach through, as shown in Figure 2.
• Corresponding holes in the wall of the guide rail 5, through the lower part 12 of the holder 1 and, in contrast, narrowed in its upper part 11 are aligned with one another, so that the screws 4 are inserted and preferably self-tapping in the narrowed holes of the upper part 11 so that the fixing of all with this screw connection of successively detected parts is simultaneously achieved.
• the film hinge 13 is folded towards itself.
• FIGS. 1 and 2 the toothed disk 2 is equipped with a toothed disk bolt, while in FIG. 3 a hub is shown instead of this bolt.
• a toothed belt shown in FIG. 1 is used made of a plastic band with teeth molded onto it, which fit into corresponding tooth formations in the jacket area of the Engage toothed lock washer 2 This type of toothing is easily interchangeable with others
