COUPLING MECHANISM FOR DRIVESHAFT TRANSMISSION ASSEMBLY |
摘要 |
A driveshaft transmission assembly may include a coupling mechanism for coupling a radial bearing assembly to a driveshaft. The coupling mechanism may include a bearing cap for creating an interference fit with a downhole portion of the radial bearing assembly. The coupling mechanism may include locking pins and a retention sleeve to retain the locking pins in grooves of the driveshaft and openings in the radial bearing sleeve. The radial bearing assembly may include a catch mechanism for preventing the loss of certain driveshaft transmission assembly components downhole in the event of a failure of the driveshaft transmission. The coupling mechanism may prevent the loss of the driveshaft downhole subsequent to separation of certain driveshaft transmission assembly components. |
