Task support equipment for correcting deformed bicycle wheel

Abstract

A bicycle wheel consists of a hub, spokes, nipples and a rim. The rim deforms from true circle to irregular circle when a worker assembles the wheel. People can ride a bicycle in safety when the rim is the true circle. The worker needs to correct the deformed rim. The worker can correct the deformed rim through the use of a relation between a nipple position to rotate a nipple rotation angle and rim displacements. I developed a task support equipment to correct the deformed rim through the use of the relation. The worker does not need to know the relation through the use of the developed task support equipment. The worker can correct the deformed rim through the use of the developed task support equipment. The developed task support equipment shows the worker the nipple position to rotate the nipple rotation angle. The worker rotates the nipple as shown by the developed task support equipment. I measured the relation between the nipple rotation angle and the rim displacements. I suggested a method to calculate the corrected rim displacements through the use of the relation. I made up a hardware and a software in the task support equipment. I implemented the method in the software. I checked performance of the developed task support equipment. I corrected the deformed rim through the use of the developed task support equipment. The results have shown the usefulness in the developed task support equipment for correcting the deformed rim.
