Flexible transmission system for use in agricultural machines and tools in general

Abstract

A flexible transmission system having a connection element for cables, which transmit rotation from the drive shaft to the dispensers, transmission housings are used. These are arranged in a manner to allow that possible vertical oscillations of the equipment, caused by irregularities in the ground, so not to interfere in the consistency and regularity of the rotation transmission, maintaining the product deposition rate for which the machine was initially regulated, to guarantee its productivity and using, to achieve this, a reduced number of component parts. This facilitates not only the assembly but also the maintenance of the equipment, with direct consequences on its production cost.

Claims

1. A flexible transmission system for application in agricultural machinery, the transmission system comprising: a first transmission housing, which couples axially to a drive shaft; wherein the drive shaft is coupled tangentially to an end of a first transmission cable, in whose opposite end is coupled to an intermediate shaft located in a second transmission housing, wherein the intermediate shaft also couples axially to a third transmission housing, which couples tangentially to one end of a second transmission cable, in whose opposite end is coupled a fourth transmission housing to rotatably drive a shaft of a dispenser.
