Abstract
A floor care machine realized in the form of a floor polishing machine contains a driven pad, the height of which pad can be adjusted automatically to adjust the application pressure to take the characteristics of the floor into consideration. For this purpose, between the driving element and the driven element, there is a transmission element which forms a torque regulator. For this purpose, the driven element can be rotated with respect to the driving element opposite to the working direction of rotation and can also be displaced axially, whereby the transmission element with a clamping element automatically regulates the displacement and rotation, thereby acting as a torque regulator to regulate the height of the pad with respect to the floor as a function of the torque.
Claims14
A rotating disc-type floor polishing machine with at least one floor polishing disc in the form of a pad that can be driven in rotation, which is designed in particular in the form of a high-speed machine, whereby a frame supports a drive with the pad, and is supported by means of guide elements so that it can be moved over the floor, and the height of the pad can be adjusted with respect to the floor to set the application pressure, taking the characteristics of the floor surface into consideration, wherein the drive is connected with a driving element that is rotationally mounted in the axis of rotation of the pad, which driving element is connected by means of transmission elements with a coaxial driven element as the drive shaft for the pad, and that the driven element is mounted so that it can rotate with respect to the driving element and can be displaced axially, whereby the transmission element with a clamping element automatically regulates the displacement and rotation, thereby acting as a torque regulator to regulate the height of the pad with respect to the floor as a function of the torque.
A floor polishing machine, such as a floor buffing machine, with at least one disc-like floor polishing element like a pad or brush wholly or partially in contact with the floor that can be driven in rotation, whereby a frame supports a drive with the floor polishing element or elements, and is supported by means of guide elements so that it can be moved over the floor, and the height of the floor polishing element or elements can adjust with respect to the floor to set the application pressure, taking the characteristics of the floor surface into consideration, wherein the drive system is connected with a driving element that is rotationally mounted in the axis of rotation of each floor polishing element, which driving element is connected by means of a transmission element with a coaxial driven element as the drive shaft for the floor polishing element, and that the driven element is mounted so that it can rotate with respect to the driving element and can be displaced axially, whereby the transmission element with a clamping element automatically regulates the displacement and rotation of the driven element in respect of the driving element, thereby acting as a torque regulator to regulate the height of the floor polishing element with respect to the floor as a function of the torque.
