Idler pulley adjustment device

摘要

A device for adjusting idler pulleys to insure proper alignment of two or more pulleys to prevent belt slippage. The device has a first adjustable member attached to a frame with a second adjustable member attached to the first. The first and second members are adjustable about mutually perpendicular axes. The idler pulley is supported on a shaft attached to the second member for rotation about a third axis, substantially perpendicular to the first two axes. An adjusting arm having a pair of substantially perpendicular slots controls rotation of the first member within limits.
