Abstract
1,007,128. Expanding wheel gear and control. ETABLISSEMENTS A. CAZENEUVE and H. R. BRUET. April 3, 1962 [April 4, 1961], No. 12655/62 addition to 889,445. Heading F2D. In an expanding V-belt pulley variable-speed gear for a machine tool, wherein a driving pulley 1, 3 is manually controlled through a follow-up liquid pressure servomotor as in the parent Specification, the servomotor comprises a cylinder 7 secured to an axially fixed pulley flange 1 fixed on a driving shaft 2 and an annular piston 8 integral with a slidable pulley flange 3 slidably keyed at 4, 5 to the driving shaft within the cylinder, and a distributer valve arranged outside the pulley 1, 3 and comprising a fixed body 18, a pilot spool 34, 35 actuated by a lever 40 located by a spring detent 42 engaging a notched sector 41, and a follow-up ported sleeve 23, the position of which is determined by the slidable pulley flange 3 connected thereto by a lever 29, 31. Actuation of the spool 34, 35 connects the cylinder 7 to pressure or exhaust lines 19, 21 through sleeve ports 25, 26, in accordance with the direction of movement, such connection persisting until cut off by the follow-up movement of the sleeve 23. If, e.g. due to leakage, the flange 3 is shifted leftward by belt tension, the sleeve 23 is rightwardly moved to connect the cylinder 7 to the pressure line 19 through the port 25 to return the flange 3 to its original position determined by the lever 40, thereby automatically correcting abnormal displacement of the flange 3.
