Abstract

PURPOSE: To obtain a small and stable, direct operated type variable-speed feeding mechanism, which can feed a turning shaft by a mechanism capable of giving continuous, variable-speed feed to a turning shaft, while holding the turning shaft by two driving rollers disposed in the manner that their axes intersect to each other, the feeding speed of said turning being varied by changing the angle of intersection of the above two driving rollers.
CONSTITUTION: There is provided a mechanism for giving continuous and variable- speed feed to a turning shaft 1, which can be used for feeding a tool rest of a machine tool, a blank of a press, etc. The turning shaft 1 is held between two rolllers 2, the axes II and II' of which intersect to each other so that the shaft 1 can be turned and also fed along its axis I by the drive of the rollers 2. Further, arrangement is such that the angle θ of intersection of axis I and axis II can be changed simultaneously on both sides of the shaft 1. With such an arrangement, the driving force of rollers 2 is used directly as the feeding force of the shaft 1, and any gears or cams are not employed in the mechanism. Therefore, it is enabled to reduce the size of the apparatus, to operate the same in a stable manner, and to obtain an economical direct-operated type stepless speed changing apparatus.
