Static Analysis of Stator Housing of Screw Drilling Rig

Abstract:

Screw drilling rig’s hard core is motor unit assemblage. Stator housing’s thread tool recess is a key component and a weak link of motor unit assemblage. The finite-element method was used to do some static analysis of the thread tool recesses which were in the same conditions and different shapes, in order to improve the screw drilling rig’s operating life and reduce the failure accident. According to the nephograms and curves about the tool recesses’ stress, the most dangerous position is thread root. Minimizing the sectional dimension’s changing and increasing the chamfering’s radius are effective way to reduce thread tool recess’ stress concentration.
