Abstract

1405398 Abrading E B HEFFRAN Jnr 5 March 1974 [8 March 1973] 9849/74 Heading B3D A compound motion rubbing machine comprises a drive shaft 14 journalled in a frame 11, a second shaft 25 eccentrically carried by the drive shaft, a gear-wheel 31 stationarily mounted on the frame in coaxial relation with the drive shaft, a ring gear 32 internally larger than the exterior of the gear-wheel rotatably mounted on the second shaft 25 in coaxial relation therewith, the ring gear being disposed around and in rolling engagement with the gearwheel, and a rubbing shoe 12 carried by the ring gear for simultaneous eccentric and turning movement relative to the frame whereby points on the shoe move along generally epicycloidal paths. As described, the machine is a portable sander and the rubbing shoe consists of a sheet of sandpaper 30 fastened to a pad of yieldable material 28 on a backing plate 29. The shaft 14 depends from a motor, such as a rotary air motor, in the frame 11, the shaft being journalled in a bearing 15 in a plate 18 of the frame. The plate is formed with the gear 31 coaxial with the axis 13 of the drive shaft 14. The second shaft 25 is eccentric of shaft 14 and carries a ball bearing 36 on which a casing 26 is journalled. The lower part of the casing is secured to the rubbing shoe and the upper part has a recess 39 in which the ring gear 32 is located. The gears 31, 32 engage, gear 31 having 36 teeth and gear 32 having 39 teeth. A counterweight 37 is secured to the second shaft 25. During rotation of the drive shaft 14, the shaft 25 and rubbing shoe orbit around the axis 13, and the gears 31, 32 cause rotation of the casing and shoe about the axis 27 of the second shaft so that abrasive particles on the sandpaper move along epicycloidal paths.
