ABSTRACT:
A belt-type power transfer assembly for driving the separating mechanism of a rotary combine harvester is disclosed wherein the assembly includes spaced apart driving and driven pulleys, an endless flexible belt interengaged between the pulleys to transfer rotational power therebetween and spring-loaded tensioning means operably engaged with the flexible belt to take up the slack thereof and to maintain proper tension therein when transferring rotational power. Stop means are associated with the spring-loaded tensioning means for restricting biasing movement thereof in the direction of the flexible belt, causing the tensioning means to act as fixedly positioned tensioning means after an initial belt tensioning movement thereof. The power transfer assembly according to the invention may be used to drive the separating mechanism of a rotary combine harvester.
