The centrepiece of this solution is the drylin® ZLWseries of toothed belt axes , which are mounted along the longitudinal struts of the black window frame on the right and left. With a clearance height of just 31 millimetres, these toothed belt axes are the perfect choice for light adjustment and positioning tasks, especially when space is limited.
The windows are driven by a DC motor from igus®. With a flange dimension of 42 millimetres, this is also very space-saving, as it does not require a motor flange, coupling or complex external power electronics. It is also resistant in a wide temperature range between -10 °C and +60 °C. When the yacht passenger presses a switch, the motor starts up. The toothed belts now move on both sides of the window frame, connected to each other by a synchronised shaft. And thus the carriages mounted on the profile guides, to which the window pane is in turn attached.
The carriages slide on the aluminium rail via bushes made of high-performance plastic using theWJ200UM series housing bearings . Thanks to microscopically small solid lubricants, hygienic, low-friction and quiet dry operation is possible without external lubricants. This minimises the need for maintenance.
Glaskeil also uses the dryve D5, an igus® motor control system that enables fast commissioning. Designers only need to connect the voltage source, control signals and the motor to the output stage. A signal, triggered by a connected button, then starts and stops the motor. A second signal is used to change the direction of rotation. The speed of the output stage can be set via eight microswitches on the housing. Settings can also be made via smartphone, tablet or laptop. Glaskeil can then set the travel mode, positions, accelerations, speed and pause times of the linear axis in just a few minutes via an intuitive browser interface. The high rated current of 10 A and 30 A peak current also produces powerful and dynamic movements on request.
Another advantage: thanks to a sophisticated combination of materials and microchips, the power amplifiers operate particularly quietly and with low vibration at all speeds. "We don't have to worry about annoying noises, which can occur with many inferior power amplifiers," emphasises Mirco Eisenhauer. "This is an important point for our customers in the premium segment."
