Title:
FREE-MASS AND INTERFACE CONFIGURATIONS OF HAMMERING MECHANISMS
Document Type and Number:
WIPO Patent Application WO/2012/058375
Kind Code:
A3
Abstract:
The design of the free-mass in an ultrasonic driller/corer (USDC) has been refined in order to improve the performance and operational reliability of the system. In one embodiment, the improvements in performance and operational reliability include decreasing the impact surface area of the free-mass to increase the transfer of impact energy from the piezoelectric transducer and reductions in the likelihood that the system will jam.
