Description

The invention relates to a toothed belt axle with a clamping device.In toothed belt axles known from the prior art, a force-transmitting connection between an end region of a toothed belt and a carriage by means of a clamping device is known. With the clamping device, the tensile forces introduced by a drive device onto the toothed belt can be transmitted to the slide accommodated in a profiled body so as to be linearly movable. A known clamping device has a clamping body which is provided with a slot for receiving the end region of the toothed belt, wherein the toothed belt can be received in the slot in a force-fitting and / or form-fitting manner. Furthermore, a connecting means is provided for fastening the clamping body to the slide.EP 2 110 579 B1 discloses an electric linear drive with a housing which has two end-face end covers and an intermediate piece extending therebetween, which together delimit a housing interior in which a toothed belt wound around two deflection rollers arranged in the region of the end covers is arranged, which toothed belt is motion-coupled through a longitudinal slot formed in the wall of the intermediate piece to an output part arranged outside the housing, wherein a strand of the toothed belt covers the longitudinal slot formed narrower than the toothed belt from the inside and wherein at least one deflection roller is arranged in the interior of the end cover assigned to it, wherein the longitudinal slot merges at least one end face into a slot-shaped mounting recess adjoining it in axial extension, the side wall of the cover receiving the deflection pulley adjoining the intermediate piece is formed in the side wall of the cover, the width of which is greater than the width of the toothed belt, so that the toothed belt can be passed through the mounting recess for its mounting and dismantling.The object of the present invention is to provide a toothed belt axle which is simple to handle and inexpensive to produce.The object is achieved by a toothed belt axle having the features listed below:The toothed belt axle according to the invention has a toothed belt, a toothed belt pulley, a deflection element, a profile body extending along an axis of movement, a carriage and a clamping device, wherein the carriage has a first end face into which a first receiving opening, extending along the axis of movement, is introduced for receiving the clamping device, wherein the profile body is designed for linearly movable guidance of the carriage, wherein the toothed belt can be driven by means of the toothed belt pulley and deflected by means of the deflection element, wherein the carriage can be moved in the profile body by means of the toothed belt, wherein the clamping device has a clamping body, a pressure plate, an annularly designed supporting body and a pressure element, wherein the clamping body has a front side, a rear side, a receiving space designed as a slot and a supporting section, wherein the receiving space extends from the front side along the movement axis and passes through the clamping body transversely to the movement axis, wherein the receiving space has a first inner surface and a second inner surface opposite the first inner surface, wherein the pressure plate has a pressure plate top side with toothing and a pressure plate bottom side, wherein the toothed belt has a toothed belt inner side with toothing, a toothed belt outer side and at least one end region, wherein the pressure plate and the end region are received in the receiving space in such a way that the toothed belt outer side faces the second inner surface, the pressure plate bottom side faces the first inner surface and the toothed belt inner side faces the pressure plate top side, wherein the toothing of the pressure plate top side is formed complementary to the toothing of the toothed belt inner side, wherein the pressure plate is pressed against the toothed belt with the pressure element abutting the pressure plate bottom side in order to press the toothed belt outer side against the second inner surface, wherein, wherein the supporting body surrounds the supporting section in order to prevent widening of the receiving space, which widening is caused in particular by the pressure element.Widening of the clamping body can lead to the toothed belt slipping out of the receiving space, as a result of which the operational reliability for the toothed belt axle would be questioned. Furthermore, an expansion of the clamping body could lead to a clamping of the clamping device in the receiving opening, so that a simple dismantling of the clamping device from the slide would be questioned and possibly damage to the slide and / or the clamping device could occur.The widening of the receiving space appears as an increase in the distance between the first inner surface and the second inner surface and is prevented according to the invention in that a force flow introduced into the clamping body by the pressure element and the pressure plate is diverted from the support ring by means of the support ring, so that this force flow does not lead to a deformation of the clamping body.By providing the first receiving opening, the clamping device can be lowered at least in regions into the carriage, whereby the required installation space can be reduced. In addition, the clamping device can be inserted into the first receiving opening to such an extent that, starting from a functional position in which it surrounds the support section, the support ring does not risk slipping off the support section, as a result of which the function of the support ring would be questioned. The front side is the side of the clamping body which during operation faces away from the carriage and via which the toothed belt can be introduced into the receiving space. The rear side is the side of the clamping body which faces the carriage during operation, i.e. the side which first enters the first receiving opening when the clamping device is inserted into the latter. The inner side of the toothed belt is the side of the toothed belt which, during operation, bears against the toothed belt pulley. The toothed belt outer side is the side of the toothed belt which during operation points away from the toothed belt pulley. By pressing the pressure plate against the toothed belt, the positive connection between the toothed belt and the clamping body is reinforced, whereby the risk of the toothed belt slipping out is reduced.The support body can preferably be moved into the functional position by means of pushing on, but also by means of screwing on or pressing on. Between the outer contour of the clamping device and the inner contour of the first receiving opening, a clearance fit is preferably provided. The length of the support ring extending along the movement axis and / or a thickness of the support ring can be selected depending on the load thereof to be expected. Thus, a short support ring with a small thickness can be provided under low load and a long support ring with a large thickness can be provided under high load.The pressure element is preferably designed as a screw, in particular as a space-saving threaded pin, and the clamping body has a thread for screwing in the screw. The thread extends transversely to the movement axis from an outer circumferential surface, in particular a circular cylindrical outer circumferential surface, of the clamping body into the receiving space.The deflecting element is preferably designed as a deflecting roller or as a toothed belt pulley.Preferably, the support body is of circular ring-shaped design. The mounting of the supporting body on the supporting section can thus take place in any desired rotational orientation.The support section is preferably at least partially annular, in particular at least in regions in the form of a circular ring.Preferably, the first inner surface and the second inner surface are oriented parallel to each other.Further features which develop the invention are the subject matter of the dependent claims with the features listed below:Preferably, a first stopper is protruded outward from the outer circumferential surface in the radial direction, which is disposed between the front side and the support portion. The first stop has, at least in regions, an outer diameter which is greater than the inner diameter of the supporting body. This makes it possible to prevent the support body from slipping off from the support portion toward the front side. Furthermore, the clamping body is designed in such a way that the support body can be brought along the movement axis via the rear side to the support section.Preferably, a second stop protrudes from the first inner surface in the direction of the second inner surface, in particular adjacent to the front side. The second stop is configured such that, when the toothed belt and the pressure plate are accommodated in the accommodating space, the pressure plate is prevented from slipping out in the axial direction along the movement axis.Preferably, the clamping body has a through bore extending from the front side to the rear side for receiving a clamping screw, and the carriage has a clamping thread which extends from the first receiving opening along the movement axis, wherein a clamping screw is screwed into the clamping thread in order to adjust the tension of the toothed belt. Furthermore, during operation, when maintenance work is carried out on the toothed belt axle, the toothed belt tension can be kept in the required range by actuating the clamping screw. Preferably, the clamping screw and the clamping thread are designed in such a way that the toothed belt tension is increased by screwing the clamping screw into the clamping thread and the toothed belt tension is reduced by screwing the clamping screw out of the clamping thread.The through bore preferably has a, in particular circular cylindrical, counterbore into which the head of the clamping screw can be received, whereby it can be avoided that elements protrude on the front side, which elements risk injury and / or damage.Preferably, the first receiving opening has a guide contour and the clamping body has a guide section complementary to the guide contour. By way of example, it is provided that the receiving opening has a non-round profile in a cross-sectional plane oriented transversely to the movement axis, and that the clamping body has a corresponding profile at least in sections. This realizes a specification for a spatial orientation between the slide and the clamping body and, associated therewith, a rotation prevention for the toothed belt accommodated on the clamping body. The profiles corresponding to one another can be designed, for example, as planar surfaces.The clamping body is preferably formed from a light metal, in particular from aluminum. In this way, the mass moved during operation can be reduced, as a result of which the energy requirement can be lowered. In addition, manufacturing costs can be reduced in this way. A loss of strength associated with the provision of light metal, in particular aluminum, in comparison with the use of a stainless steel can be compensated for by the supporting body with which the loads described above are accommodated.Alternatively, the clamping body can be formed from a plastic, wherein the above-mentioned applies analogously with respect to light metals.The support section preferably has a larger outer diameter than the remaining outer circumferential surface of the clamping body. In this way, the application of the supporting body to the supporting portion can be facilitated, whereby the handling can be increased. In addition, it is possible to prevent such a fit as well as a fit provided with respect to the support portion from being provided with respect to the outer circumferential surface extending up to the support portion, whereby manufacturing costs can be reduced.Preferably, the outer diameter of the support section and the inner diameter of the support body are the same. In this way, widening of the receiving space can be prevented even further, as a result of which the operational reliability can be increased. Further preferably, a fit is provided between the support section and the support body. This fit is still more preferably a transition fit in order to enable a low-resistance sliding-on and at the same time minimize the play between the supporting body and the supporting section.Preferably, the clamping body is designed rotationally symmetrical at least in regions. In this way, cost-effective production methods can be used, for example. The method of rotation can reduce the manufacturing cost.Preferably, the toothed belt axle further comprises a further clamping device, wherein the carriage further comprises a further end face into which a second receiving opening arranged opposite the first receiving opening is introduced for receiving the further clamping device, wherein the toothed belt comprises a further end region which is received in the receiving space of the further clamping device.The toothed belt can be clamped and preferably tensioned as follows: first, an end region of the toothed belt is inserted into the receiving space of a clamping body. The corresponding pressure plate is then introduced into the receiving space, preferably via the openings of the slot present on the outer circumferential surface. Alternatively, the pressure plate can be inserted into the receiving space first and then the end region of the toothed belt. Subsequently, the support body is applied to the support section. Then, with the pressure element abutting on the pressure plate bottom side, the pressure plate is pressed against the toothed belt, whereby the toothed belt outer side is pressed against the second inner surface. The clamping device is then introduced into a receiving opening, i.e. inserted into the latter and fastened therein, preferably by means of the clamping screw. Finally, by screwing the clamping screw into or out of the clamping thread, the tension of the toothed belt can be adjusted.An advantageous embodiment of the invention is shown in the drawing. The following shows: FIG. 1 shows a toothed belt axle according to the invention, FIG. 2 shows a profile body and a carriage of the toothed belt axle illustrated in FIG. 1, FIG. 3 is an abstract sectional view of a toothed belt axle according to the invention, FIG. 4 shows the carriage shown in FIG. 2 and a clamping device of the toothed belt axle shown in FIG. 1 in an exploded perspective view, FIG. 5 is an abstract illustration of a clamping device with a supporting body surrounding a supporting section, FIG. 6 shows the clamping device shown in FIG. 5 with a support body arranged next to a clamping body.FIG. 1 shows a toothed belt axle 200 according to the invention with a carriage 300 and a profiled body 230. The profile body 230 is oriented along a movement axis 500 and is designed to guide the carriage 300 linearly along this movement axis 500. The carriage 300 is driven by means of a toothed belt 210 (cf. FIG. 3 ), not shown in FIG. 1. In this case, the toothed belt 210 is driven via a toothed belt pulley 220, not shown in FIG. 1 (cf. FIG. 3 ), which is accommodated in a deflection housing 232 attached to the end side of the profiled body 230. The toothed belt pulley 220 is connected to a motor flange 250, not shown in FIG. 1 (cf. FIG. 3 ), on which, for example, an electric motor for driving the toothed belt pulley 220 can be provided. In this case, the toothed belt pulley 220 rotates about a first axis of rotation 510. On the side of the profile body 230 opposite the toothed belt pulley 220, a deflecting element 240 (cf. FIG. 3 ), which is not illustrated in FIG. 1 and by means of which the toothed belt 210 is deflected, is provided in a further deflecting housing 234 attached to the profile body 230 on the end side. In this case, the deflecting element 240 rotates about a second axis of rotation 520. The profile body 230 shown in FIG. 1 preferably has a cover in order to protect the toothed belt 210 from soiling and damage.FIG. 2 shows the profile body 230 and the carriage 300 of the toothed belt axle 200 illustrated in FIG. 1. The profile body 230 is preferably designed with a constant profile along the movement axis 500, in particular as an extruded aluminum profile.The carriage 300 has a cuboidal carrier body 302, the upper side 304 of which can be used to accommodate a workpiece or workpiece carrier, not shown. Starting from an underside 305 facing away from the top side 304, a coupling body 307 extends, with which the carriage 300 projects into a recess 236 bounded by the profile body 230. Below the upper edge of the profile body 230, which is located at the top in the illustration, a first receiving opening 312 extending along the movement axis 500 is introduced on the coupling body 307 into a first end face 310 of the coupling body 307, which is aligned in the axial direction purely by way of example. This first receiving opening 312 serves, as will be described in more detail below, to receive a clamping device 100.FIG. 3 shows an abstract sectional illustration of a toothed belt axle 200 according to the invention. Starting from the representations of FIGS. 1 and 2, it can be seen in FIG. 3 that the carriage 300 with the carrier body 302 is arranged at least in regions outside the profile body 230 shown only in dashed lines, while the coupling body 307 is accommodated in the recess 236 of the profile body 230. The toothed belt pulley 220 and the deflecting element 240, which can likewise be designed as a toothed belt pulley, are each mounted rotatably about the first or second axis of rotation 510, 520 in the deflecting housings 232, 234 attached in each case on the end side to the profile body 230.The toothed belt pulley 220 and the deflecting element 240 are each surrounded in regions by a toothed belt 210 which extends starting from a first clamping device 100 as far as a further clamping device 100. For the following description, it is assumed that the first clamping device 100 and the further clamping device 100 are of identical design, so that a separate description of the further clamping device 100 is superfluous.The two clamping devices 100 are each introduced into mutually opposite receiving openings (not shown in more detail in FIG. 3, cf. FIGS. 2 and 4 ) of the coupling body 307.The toothed belt 210 has two end regions 216, of which one end region 216 is clamped in one of the two clamping devices 100 in each case. The toothed belt 210 illustrated in FIG. 3 has, in the lower region, a lower strand 218, which is located between the toothed belt pulley 220 and the deflecting element 240, and, in the upper region, two upper strands 219, which are located, on the one hand, between the toothed belt pulley 220 and the left clamping device 100 and, on the other hand, between the deflecting element 240 and the right clamping device 100. The two upper strands 219 and the lower strand 218 are aligned along the movement axis 500.By means of the toothed belt 210, the carriage 300 can be moved to the right along the movement axis 500. For this purpose, the toothed belt pulley 220 is driven in the clockwise direction. In addition, the carriage 300 can be moved to the left along the movement axis 500 by means of the toothed belt 210, for which purpose the toothed belt pulley 220 is driven in the counterclockwise direction.FIG. 4 shows the carriage 300 illustrated in FIG. 2 and the clamping device 100 of the toothed belt axle 200 illustrated in FIG. 1 in an exploded perspective view.A first receiving opening 312 extending along the movement axis 500 is introduced into the first end face 310. The first receiving opening 312 has, in succession along the movement axis 500, starting from the first end face 310, a first, circular and upwardly open section, a second end face 311, and a second section which has a guide contour 324. The first section has a larger inner diameter than the second section. In addition, the inner diameter of the first portion is larger than an outer diameter D 5, not shown here, of the support body 140 (cf. FIG. 6 ), so that the support body 140 can be accommodated in the first portion. Further, the outer diameter D 5 of the support body 140 is larger than the inner diameter of the second portion, so that the support body 140 can abut on the second end surface 311 without entering the second portion. This support only occurs if the support body 140 should slip off the clamping body 110 described in more detail below in an undesired manner.In addition, the carriage 300 has a further end face (not shown in FIG. 4 ) which is oriented, purely by way of example, opposite the first end face 310, and a second receiving opening 314 (concealed in FIG. 4 ) which is introduced into this further end face. For the following description, it is assumed that the first receiving opening 312 and the second receiving opening 314 are formed identically, so that a separate description of the second receiving opening 314 is omitted.The clamping device 100 has a substantially rotationally symmetrical clamping body 110 with a circular cylindrical outer circumferential surface 119. In addition, the clamping body 110 has a front side 112, a rear side 115, a receiving space 120 which originates from the front side 112 and is designed as a slot and extends transversely with respect to an axis of rotational symmetry which, in FIG. 4, is aligned coaxially with the axis of movement 500, and a support section 129 which is designed in a circular cylinder.The clamping device 100 further comprises a pressure plate 130, a support body 140 formed in the shape of a ring, and a pressure element 150. In the operating state, the supporting body 140 surrounds the supporting section 129 and is thus in a functional position (cf. FIG. 5 ).The receiving space 120 extends from the front side 112 along the movement axis 500 and passes through the clamping body 110 perpendicular to the movement axis 500. The receiving space 120 has a first inner surface 123 and a second inner surface 124 opposite the first inner surface 123.The pressure plate 130 has a pressure plate upper side 132 with a toothing, not shown in more detail, and a pressure plate lower side 134, wherein the toothed belt 210 (cf. FIGS. 3 and 5 ) furthermore has a toothed belt inner side 212 with a toothing, likewise not shown in more detail (cf. FIG. 5 ), and a toothed belt outer side 214 (cf. FIG. 5 ). The toothing of the pressure plate upper side 132 is formed to be complementary to the toothing of the toothed belt inner side 212.Projecting radially outwards from the outer circumferential surface 119 of the clamping body 110 is a first, annularly formed stop 113 which is arranged between the front side 112 and the support section 129.Second stop 128 protrudes from first inner surface 123 in the direction of second inner surface 124, in particular adjacent to front side 112. The second stop 128 is designed in such a way that the end region 216 accommodated in the accommodation space 120 in combination with the pressure plate 130 is secured against slipping out along the movement axis 500 in the direction of the front side 112.The pressure element 150 is designed as a threaded pin.A clamping screw 400 is also provided, which can be received in a through bore 127 of the clamping body 110 and can be screwed into a clamping thread of the slide 300 (not shown in FIG. 4 ) in order to adjust the tension of the toothed belt 210. The clamping body 110 further comprises a guide region 117 which is purely exemplarily embodied as a planar surface and which is embodied in a complementary manner to the guide contour 324 of the first receiving opening 312. The planar surface of the guide region 117 is oriented, when the clamping device 100 is received in the first receiving opening 312, in such a way that a surface normal of the planar surface runs transversely with respect to the movement axis 500. In FIG. 4, purely by way of example, the planar surface of the guide region 117 is also oriented parallel to the upper side 304 of the carrier body 302. The details given with respect to the alignment of the planar surface of the guide region 117 apply analogously to the alignment of the guide contour 324. Furthermore, the guide region 117 and the guide contour 324 can also be formed in a serrated or arched manner. As a result, positive engagement between the clamping body 110 and the first receiving opening 312 ensures a clear rotational alignment of the clamping body 110 with respect to the first receiving opening 312 and thus with respect to the slide 300. Furthermore, this ensures a rotation prevention for the end region 216 of the toothed belt 130 received on the clamping body 110.FIG. 5 shows an abstract illustration of the clamping device 100 with the supporting body 140 surrounding the supporting section 129. The support body 140 is accordingly in the functional position. In the configuration illustrated in FIG. 5, the pressure plate 130 and the end region 216 are accommodated in the accommodating space 120 in such a way that the toothed belt outer side 214 faces the second inner surface 124, the pressure plate lower side 134 faces the first inner surface 123 and the toothed belt inner side 212 faces the pressure plate upper side 132. With the pressure element 150 resting on the pressure plate bottom side 134, the pressure plate 130 is pressed against the toothed belt 210, whereby the toothed belt outer side 214 is pressed against the second inner surface 124. In this case, the supporting body 140 surrounding the supporting section 129 prevents the receiving space 120 from widening, in particular caused by the pressure element 150. The rear side 115 has a chamfer, as a result of which the application of the supporting body 140 to the clamping body 110 and the introduction of the clamping device 100 into the first receiving opening 312 can be simplified.FIG. 6 shows the clamping device 100 shown in FIG. 5 with a support body 140 arranged next to the clamping body 110. The support body 140 has an inner diameter D 3 as large as an outer periphery D 1 of the support portion 129. The outer peripheral surface 119 has an outer diameter D 2 that is smaller than the inner diameter D 3 and the outer diameter D 1. The first stopper 113 has an outer diameter D 4 larger than the inner diameter D 3. In this way, it is possible to prevent the supporting body 140 from slipping along the movement axis 500 in the direction of the front side 112.
