Abstract
A floor sanding machine is proposed, which consists of a case body (11) and a plurality of sanding tools (30) arranged eccentrically in the case body (11). The axes of the tool shafts (31) rotate about the axis of a central shaft (12), and the sanding tools (30) rotate about the axis of the tool shaft. The construction consists essentially of a belt drive, of which the unilaterally grooved drive belt (3) is driven on the grooved side of the main drive pulley (2) and drives a gear mechanism (5). Also on the grooved side of the drive belt (3), a belt tensioner (6) ensures that the drive belt (3) is always under sufficient tension. The tools (4) are driven via the non-grooved side of the drive belt (3).
Claims3
Floor sanding machine having a case body (11) and a plurality of grinding tools (30) arranged eccentrically in the case body (11) with tool shafts (31), in conjunction with which the axes of the tool shafts (31) are rotatably mounted about the axis of a central shaft (12) and the sanding tools (30) are rotatably mounted about the axis of the tool shaft (31), wherein the drive shaft of a drive (1) is rigidly connected via a central axis (12) to a main drive pulley (2), the main drive pulley (2) being maintained in positive engagement by means of a unilaterally and longitudinally grooved drive belt (3) with a gear mechanism drive pulley (10), tool drive pulleys (4) and a belt tensioner (6), the positive engagement being effected on the main drive pulley (2), the gear mechanism drive pulley (7) and the belt tensioner (6) via the side of the drive belt (3) provided with longitudinal grooves, and the positive engagement on the tool drive pulleys (4) being effected via the non-grooved rear side of the drive belt (3).
