Angled drive for an agriculural header assembly |
摘要 |
A header is mounted on a separate tractor and takes drive from a PTO shaft of the tractor and communicates the drive to a main drive shaft of the header longitudinal of the main beam of the header. The angle drive necessary to communicate this power is formed by three CV joints. A first CV joint is connected to the PTO shaft and a third CV joint is connected to the main drive shaft of the header. Between the first and third CV joints is provided a first shaft extending to the second CV joint and a second shaft from the second CV joint to the third CV joint. The first shaft is carried on a hanger bearing which can pivot about a horizontal axis with the first shaft mounted in a spherical bearing on the hanger bearing plate. The second shaft is telescopic. The three CV joints pivot to divide the total angle approximately equally so that each can run within a reasonable angle. The pivoting hanger bearing and the telescopic shaft accommodate relative movement between the tractor and the header.
