Abstract

An orbital shaker apparatus is provided, including a first shaft connected to a first bearing assembly at a first end and a mounting portion at the other. The first shaft is rotatable about a first shaft axis, and is connected to a motor. The second shaft has a bearing assembly on the mounting portion at one end and a platform at the other, and is aligned parallel to and offset from the first shaft by a distance. A counterweight rotor assembly is coupled to the mounting portion, and rotated by a belt driven by a pulley connected to the rotating shaft of a counterweight motor. The counterweight assembly includes two counterweight bearings, each having a counterweight wedge. The platform also includes supports for objects to be secured thereto. In use, as the counterweight rotor rotates, the second shaft, second bearing assembly, and platform describes a circular orbit with diameter 2R.
