摘要： The invention relates to an arrangement for a mobile surfacing machine, preferably for the surfacing of stone floors. A frame supports a drive motor with a motor shaft. A planet disc is rotatably mounted in the fame, with three surfacing discs arranged on shafts rotatably mounted on the planet disc. The surfacing discs are in operative connection with a belt pulley arranged on the drive shaft of the motor via a drive belt running around first belt pulleys arranged on the aforementioned shafts. The shafts of the surfacing discs are so arranged, for the purpose of controlling the rotation of the planet disc, as to be in operative connection with the frame. The operative connection comprises, for example, a belt pulley attached to the frame, second belt pulleys arranged on the shafts of the surfacing discs, and a second belt running around these and the belt pulley attached to the frame.

摘要： An oscillating spindle sander having a spindle rotatably mounted in a cabinet. An external end of the spindle is adapted to receive a sanding drum. An upper cam pulley is fixedly attached to the spindle and a lower cam pulley is rotatably attached to the spindle within the cabinet. The upper and lower cam pulleys have face-to-face annular cam surfaces having complementary sinusoidal contours with diametrically opposite lobes and diametrically opposite valleys. The upper and lower cam pulleys have a toothed rim connected by individual drive belts to a common drive pulley rotated by an electric motor. The number of teeth on the toothed rims of the upper and lower cam pulleys are different, causing the upper and lower cam pulleys to rotate relative to each other. The annular cam surfaces cause the upper cam pulley and the spindle to be oscillated in a vertical direction in response to the relative rotation between upper and lower cam pulleys.

摘要： In order to achieve a compact spindle drive which is also lightweight and consisting of few components, and where the drive motor (8) is mounted in a stationary manner in relation to the spindle drive, the spindle drive according to the invention is configured with two sets of bevel gears comprising a first larger pair of gears (11, 13) and a second smaller pair of gears (12, 14).The spindles (15, 17) can hereby be mounted in star formation in the housing and alternately enter into engagement with the first gear (11) and the second gear (12), and thus alternatively rotate the one way and the other way.At the same time, all of the spindles (15, 17) are suspended in the same plane, whereby a very uniform machining operation is achieved.Finally, the housing can be provided with a turning motor (21), which via a pinion (2, 19) can revolve the housing (1) at the same time that the spindles rotate.

摘要： A drive mechanism for a wafer processing machine of the kind which holds a silicon wafer on a vacuum chuck and rotates the wafer for processing operations on the wafer periphery or upper surface incorporates a low-speed motor, a high-speed motor and an overrunning clutch. The low-speed motor is connected to a drive shaft for the chuck through the overrunning clutch and rotates the chuck and wafer at a relatively low and precisely-controlled speed while the edge of the wafer is contoured by a grinding wheel or while the upper surface is mechanically cleaned by a brush engaged with the upper surface of the wafer. The high-speed motor is directly connected to the drive shaft and, when energized for a rinsing and drying operation, rotates the chuck and wafer in the same direction of rotation as the low-speed motor but at high speed while the wafer is being rinsed and dried after the grinding or cleaning operation. During the grinding or cleaning operation the high-speed motor is energized toward rotation in a direction opposed to the direction of rotation produced by the low-speed motor. The biasing torque so produced insures against any slack or rebounding through the overrunning clutch which could result in skipping or chattering of the engagement of the grinding wheel with the periphery of the wafer during the contouring of the periphery of the wafer or which could result in loss of clamping contact between the chuck and the wafer.
