Abstract
The mounting for a roller shaft in the frame of a conveyor is designed to reduce the vibration of the shaft and the sound produced during conveyor operation. In several embodiments, the end of the shaft is provided with a taper, and a spring which is internal to the roller is used to bias the taper into the mounting hole. The resulting tight fit of the taper in the hole greatly reduces the vibration energy of the shaft. In another embodiment, a bushing separates the shaft and the hole and is designed to grip the shaft as it is pressed into place in the hole.
