Abstract: Embodiments of the invention provide systems and methods for monitoring and removing contaminants from a conveyor surface based upon predicted frictional engagement qualities detected on a conveyor surface. In some examples, the methods may include monitoring the conveyor surface with at least one sensor configured to sense a condition on the conveyor surface. The sensor may detect the presence of a contaminant, and communicate the location of the detected contaminant to a processor. A treatment cycle may then be initiated to remove or displace the contaminant from the conveyor surface after the presence of a contaminant has been detected.

Abstract: A bearing assembly includes an outer race and an inner race. The outer race has a body extending between a pair of axial faces and defines a radially-inward facing bearing surface. The inner race is received in the outer race and has a radially-outward facing bearing surface that bears against the radially-inward facing bearing surface of the outer race. The radially-outward facing bearing surface has one or more flat surfaces removed from it. These flats on the inner race can reduce the dimensional entry requirements for insertion of the inner race into the outer race and either permits the receiving slots in the outer race to be reduced in dimension (thereby relatively thickening the wall of the outer race, which structurally strengthens the outer races) or permits the receiving slots to be eliminated altogether.

Abstract: An accumulation system for a conveyor that supports an object for movement along a path. The accumulation system including a clutch mechanism that selectively manipulates the operation of the conveyor via eddy currents to affect the movement of the object.

Abstract: A method of manufacturing a slotted entry bearing assembly includes inserting an inner race into a central space of an outer race. The outer race is configured to receive the inner race through at least one slot. Once the inner race is fully inserted into the outer race, it is rotated approximately ninety degrees within the center space, effectively locking the inner race within the outer race. After the inner race is rotated ninety degrees, a molded seal is molded between the inner race and the at least one slot. The molded seal adheres to the at least one slot and is made of a polymeric material. The molding process used to mold the molded seal may be compression molding.

Abstract: A gripper (12) is disclosed having a base (24) that extends from a first end a second end and includes resilient (32) fingers that extend from the base between the first end and the second end. The resilient fingers (32) may be configured to generally conform to and engage with articles (34) being transferred when the base is mounted to a conveyor.

Abstract: A transmission having improved heat dissipation components is disclosed. The transmission includes a housing having housing walls defining an internal chamber and a rotatable input shaft extending through one of the housing walls into the internal chamber. Power transmission components are disposed in the internal chamber and rotatably driven by the input shaft. An output shaft extends through one of the housing walls from the internal chamber and is rotatably driven by the power transmission components. A lubricating fluid is disposed in the internal chamber and lubricates the power transmission components. A cooling shroud surrounds the housing and includes a cooling passageway in fluid communication with the internal chamber. The lubricating fluid flows out of the internal chamber into the cooling passageway, through the cooling passageway, and back into the internal chamber.
