Embodiment Construction

[0023] The drawings show various preferred embodiments of the invention for purposes of illustration only. It will be readily apparent to those skilled in the art from the following discussion that alternative embodiments of the structures and methods described herein may be employed without departing from the principles of the invention as described herein.

[0024] Such as Figure 3-6 As shown, a sleeved ultrasonic transducer 40 according to the present invention has a two-piece end piece 42 comprising an internally threaded sleeve 44 of one material and a counterbore housing of the other. 46. Preferably, the threaded sleeve 44 is composed of a material such as titanium or other metal that has sufficient strength for the threads. Additionally, preferably, the housing is comprised of materials such as aluminum, other metals, or ceramics or other non-metallic materials that provide favorable thermal and / or acoustic properties, including thermal conduction, thermal expansion,...

Abstract

The sleeved ultrasonic transducer (40) has a two-part head end block (42), which includes a threaded sleeve (44) and a housing (46) made of different materials. The threaded sleeve (44) is preferably a metal such as titanium, which provides superior thread strength for mating with the extrusion bolt (24), while the housing (46) is preferably aluminum or ceramic or other metal or Non-metallic material that provides good heat sink capacity and / or transmission of vibration energy. The combination of these two components (44, 46) provides an improved ultrasound transducer.

Description

technical field [0001] The present invention relates generally to ultrasonic generators, transducers, and transducers, and more particularly, to ultrasonic transducers having a two-piece tip block or front end driver, wherein one block provides good thread integrity and the other A block provides good acoustic and / or heat transfer properties. Background technique [0002] Typical prior art stacked ultrasound transducers or transducers 10 and 12 are shown in FIGS. 1 and 2 . Both transducers 10 and 12 have a plurality of piezoelectric crystals or transducers (PZT) 14 in the shape of a ring located between a trailing block or back end driver 16 and a head end block or front end driver 18 (FIG. 1) or between 20 (Figure 2). Bolts 22 are threaded into internal threads in the head end block 18 or 20 to hold the transducer together and squeeze the PZT 14 between the head end block and the tail block. An insulating sleeve 23 insulates the PZT 14 from the bolt 22, and electrical co...
