Abstract
Apparatus and methods for achieving a high strength bonded joint between a stub connector and a shaft.
Claims24
An apparatus for transmitting mechanical power to a device, the apparatus comprising:
- a shaft having a shaft length, an outer diametral surface, an inner diametral surface, a first end, a second end, at least one of the first and second ends being open, the shaft including an adhesive injection injection port located a first distance from the first end, the shaft including an adhesive injection venting port located a second distance from the first end, the first distance not being about equal to the second distance;
- a stub adapted and configured for adhesive connection to said shaft, said stub having a first end adapted and configured to fit within the opened end of said shaft and a second end adapted and configured for connection to the device, the outer surface of the first end including means for increasing the surface area available for adhesion;
- wherein the open end of the shaft is placed over the first end of said stub and an adhesive material is placed in the gap between the outer surface of the first end of said stub and the inner diametral surface of said shaft.
The apparatus of claim 22, wherein the helical groove is adapted and configured to provide less resistance to flow of adhesive material in the helical direction than in the axial direction.
