Abstract: A pulley assembly for an automative machine and methods for the same are disclosed. The pulley assembly may include a monolithic body, an actuation assembly, and a pulley. The body may define a recess extending from a first end surface toward a second end surface thereof. The recess may separate an upper portion from a lower portion of the body. The body may define a bore extending through the upper and lower portions of the body. The bore may be threaded along a length thereof. The actuation assembly may include a mechanical biasing element having a threaded portion. The mechanical biasing element may be disposed in the bore such that the threaded portion thereof is threadably coupled with the threaded portion of the bore. The pulley may be rotatably coupled with the upper portion of the body such that the pully moves when the upper portion is actuated.

Abstract: A pulley assembly for an automative machine and methods for adjusting the pulley assembly are disclosed. The pulley assembly may include a monolithic body, an actuation assembly, and a pulley. The monolithic body may define a recess extending from a first end surface toward a second end surface thereof. The recess may at least partially separate an upper portion of the monolithic body from a lower portion of the monolithic body. The actuation assembly may be operably coupled with the monolithic body and configured to apply a biasing force to the upper portion of the monolithic body to actuate the upper portion of the monolithic body towards or away from the lower portion of the monolithic body. The pulley may be rotatably coupled with the upper portion of the monolithic body such that the pulley moves when the upper portion of the monolithic body is actuated.
