Abstract: A flexible coupling device is disclosed adapted to connect a first rotatable shaft with a second rotatable shaft. The coupling device generally includes a pair of opposing hubs, each of which is adapted to be secured to a respective shaft. A continuous and flexible coupling element extends between the hubs. The coupling element is nonremovably associated with a pair of inner clamp rings, each adapted to be connected to one of the hubs. The coupling element can be molded about the inner clamp rings and can be adhesively secured to the rings.

Abstract: The present invention is generally directed to a take-up frame assembly that is adapted to maintain a conveyor belt under constant tension. The take-up frame assembly, in one embodiment, can include a fluid cylinder having a retractable piston. The piston is interconnected with a bearing mounted to a shaft supporting the conveyor belt. The fluid cylinder includes a fluid regulator which can be used to maintain constant pressure within the cylinder and to thus apply a constant force to the bearing. The take-up frame assembly can also be used in combination with a controller and belt alignment devices which sense the relative position of the conveyor belt. When the conveyor belt falls out of alignment, the controller is capable of varying the pressure within the fluid cylinders in order to realign the belt.

Abstract: The present invention is generally directed to a bearing assembly suitable for use in a wet or harsh chemical environment. The bearing assembly includes a bearing housing that is resistant to corrosion, oxidation, contamination and deterioration when exposed to water, bacteria and various chemicals. Specifically, the bearing housing in accordance with the present invention is made from sintered stainless steel. In one embodiment, the housing can also be impregnated with a polymeric sealant which prevents the housing from entrapping bacteria and chemicals to which it may be exposed.

Abstract: The present invention is directed to a flexible coupling device adapted to connect a first rotatable shaft with a second rotatable shaft. The coupling device generally includes a pair of opposing hubs, each of which is adapted to be secured to a respective shaft. A connecting sleeve made from an elastomeric material extends between and engages each of the hubs. According to the present invention, the connecting sleeve also contains a rigid member defining at least one failsafe element or rigid engaging element that prevents the hubs from disengaging the connecting sleeve should the elastomeric material begin to wear and fail.
