Stator inserts, methods of fabricating the same, and downhole motors incorporating the same |
摘要 |
The present invention recites a downhole motor and method of manufacture wherein a mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator is provided. A flexible sleeve is provided over the mandrel and the flexible sleeve and the mandrel are provided into a mold. Additionally, a reinforcing material is introduced into the mold to fill space between the flexible sleeve and the mold. Said material is then solidified to bond the reinforcing material and the flexible sleeve. The solidified reinforcing material and flexible sleeve are then removed from the mold such that a stator insert is fabricated. |
