Abstract
A ledger mechanism for a rod cutting apparatus comprises a ledger; a coupling rod on which the ledger is fixedly mounted; and a pair of spaced gear arrangements each having a gear ratio of 2:1 to generate a pair of points, one point on each gear arrangement, which reciprocate in synchronism along straight parallel paths, wherein the coupling rod is pivotally coupled at one end to one of said pair of points on one gear arrangement, and at its opposite end to the other of said pair of points on the other gear arrangement so that the ledger reciprocates linearly.
Claims7
A ledger mechanism for a rod cutting apparatus, comprising a ledger;
- a coupling rod on which the ledger is fixedly mounted;
- and a pair of spaced gear arrangements each having a gear ratio of 2:1 to generate a pair of points, one point on each gear arrangement, which reciprocate in sycnhronism along straight parallel paths, wherein the coupling rod is pivotally coupled at one end to one of said pair of points on one gear arrangement, and at its opposite end to the other of said pair of points on the other gear arrangement so that the ledger reciprocates linearly, each gear arrangement comprising a planetary gear which orbits around an axis of a fixed gear and meshes with said fixed gear through an idler gear, first adjustment means for adjusting a first distance between the axes of said fixed and planetary gears, and second adjustment means for adjusting a second distance between the axis of said planetary gear and said point on said gear arrangement.
