PROBLEM TO BE SOLVED: To provide an inexpensive revolution roller bearing using a both-head tapered roller of a scroll compressor by facilitating the assembly of the revolution roller bearing.SOLUTION: Since there is no need of the revolution of only a bearing, a both-head tapered roller is lightly press-fitted in an elliptical pocket hole formed by overlapping and decentering guide holes of a fixing and revolution sides to make a roller with a cage, which facilitates handling. The decentering is released before the start of an operation.SELECTED DRAWING: Figure 4 |
