Now, the tensioning and damping devices 16 will be referred to to the figures 4 and 5 explained in detail, wherein functional to the main bearing receiving device described above identical parts generally have the same reference numerals wear:

Each tensioning and damping device 16 includes a than on the Rails 18 movable carriage trained base element 20 with four wheels 34. This car 20 is from a driven in the figures not visible electric motor. In a central recess 142 of the carriage 20 are transversely to the plant longitudinal direction running substantially horizontal Rails 52 and 54 arranged. On this one is designed as a carriage intermediate element 22 via Guide pieces 148 slidably mounted. That too Intermediate member 22 is not one in the figures visible electric motor movable.

The intermediate element 22 has upwardly open trough-shaped Shape with a bottom plate 150. To these are four in a line extending transversely to the plant longitudinal direction arranged fork flaps 152 formed, which are in Specify plant longitudinal direction extending pivot axes. Two of these bearing plates 152 are in the vicinity of the lateral Edge of the intermediate element 22 is arranged. In them is in each case a connection portion 154 of a cylinder housing 156 of a hydraulic cylinder 157 via a bolt 158th held pivotally. The hydraulic cylinders 157 each comprise Piston rods 159 and form vertical support elements 24. The upper ends of the piston rods 159 each carry a support device 28, the present case as a bearing angle is trained.

At the upper ends of the cylinder housing 156 are respectively extending in plant longitudinal direction journals 160 molded. In the bearing pin 160 grip fork straps 162, which in turn respectively to the distal end of Piston rod 164 mounted on a hydraulic cylinder 166 are. Its cylinder housing 168 in turn has a Terminal portion 170, which in each case with one of the inner Bearing plates 152 connected to the bottom plate 150 is. Through the bearing plates 152 and the connection sections 154 and 170, the hydraulic cylinders 157 and 166 are tip-proof held.

By the hydraulic cylinder 166, the angle between the hydraulic cylinders 157 and the plane of the bottom plate 150 and thereby the lateral position of the bearing angle 161 can be adjusted.

The hydraulic cylinders 157 and 166 are with a valve block 174 connected, in turn, of the tax and Data acquisition device 120 is driven. This one gets also signals from position or displacement sensors 176, 178, 180 and 182, through which the actual stroke of the hydraulic cylinder 157 and 166 is displayed.

The system 10 is operated as follows:

First, to adjust the main bearing receiving devices 14:

Then be from the tax and Data acquisition device 120, the electric actuators 64 of the vertical support members 24 driven so that these adjust vertically and the upper intermediate element 26 and the support device 28 in the desired Move vertical position. It is by the Forced synchronizing 68 ensures that the stroke the vertical support elements 24 is the same, the upper intermediate element 26 so in every vertical position parallel to lower intermediate element 22 is aligned. From the tax and data acquisition device 120 are further the Electric motors 88 of the main bearing receiving devices 14th so controlled that the base plate 82 of the respective Auflagereinrichtungen 28 in the desired position to the pivoted by the bearing pin 86 predetermined vertical axis.

In the same way, the electric motors 100 of the respective main bearing receiving devices 14 so controlled, that the distance between the support elements 110 of the respective main bearing receiving device 14 the individual main bearing 30 of the respective track element 32 corresponds.

A review of the actual settings of the various Electric control elements is through the displacement sensors 122 to 132 possible, which the current positions the control elements of the control and data acquisition device 120 show. This is for achieving the desired high production accuracy and due to the requirements especially helpful for quality assurance.

After the settings have been made this will be the setting corresponding track element 32 lowered from above so that the main bearings 30 on the support plates 112 of the support elements 110 of the three main bearing receptacles 14 of Appendix 10 come to rest.

Of the load cells 134 and 136 are the bearing loads of each support element 110 determined individually. From the control and data acquisition device 120 are then the electric motors 118 of each support element 110 so controlled and thereby the height the support plates 112 of the respective support elements 110 so finely adjusted that the desired distribution of Auflagerkräfte exists.

Then, the valve block 174 of the control and data acquisition device 120 so controlled that the hydraulic cylinder 157 and 166 of the total of eight tensioning and damping devices 16 in the course of the individual Fahrwegelements 32 corresponding position to be moved, in which the respective bearing angles 161 on the base body 172 of the track element 32 attack. In this way, the between two main bearing receiving devices 14 lying section the Fahrwegelements 32 additionally supported. This has the Advantage that by the processing of the preassembled Fahrwegelements 32 occurring vibrations of the track element 32 be damped or possibly completely suppressed, whereby the manufacturing accuracy is increased.
