Fluid-actuated roller assembly with adjustable circumference
The patent US12043505B2 describes an innovative apparatus designed around a central axis, featuring a roller and a bushing. The roller has an outer surface and an inner bore, while the bushing is partially housed within this bore. Key components of the bushing include a sleeve with a bladder that expands radially when fluid is introduced, thereby reducing the inner bore's operative circumference. The bushing also features a flange that acts as a vessel for the fluid, which is in communication with the bladder. An actuator, comprising a piston and a screw, facilitates the flow of fluid from the flange to the bladder, allowing for controlled engagement between the bushing and a shaft inserted into the sleeve. The design includes an alignment feature to ensure proper rotational positioning of the roller relative to the bushing.
Further claims detail the structural aspects of the roller and bushing, including the use of a hollow cylindrical tube and an annular body, which can be coupled via weldment. The apparatus can accommodate multiple bushings and shafts, with provisions for frictional engagement to inhibit unwanted rotational movement. The patent also outlines methods for inserting a shaft into the bushing and actuating the system to engage or disengage the bushing from the shaft. Additionally, the patent describes a system comprising multiple such apparatuses, which can be utilized in applications like yarn or cloth feed roller systems, enhancing their functionality and operational efficiency.
