Sažetak
Positive Displacement Motor (PDM) is one of the most commonly used deep hole power drills. The thrust ball bearing unit is one of the vulnerable parts of the PDM. Failure of the thrust bearing greatly affects the PDM and can drastically reduce its drilling efficiency. In order to improve its service life, we have designed a new deep cavity tapered roller thrust bearing. In this analysis, we will evaluate the new product. In the past, results have shown that there is a serious stress concentration at both ends of the roller. The new deep cavity design will result in the improvement of the stress factor of tapered rollers. If the cavity depth and diameter are too small, the stress concentration at both ends of the roller becomes serious. If they are too large, the stress on the middle part of the roller is also too high. Deformation of the roller increases with an increase in the deep cavity’s length and depth. Consequently, the deep cavity design can improve the PDM.
