| 20080292393 | PLASTIC SEMI-PERMANENT RETAINER RING - A semi-permanent retainer mechanism for securing a shaft within a component by forming a semi-permanent ridge on the shaft is provided. The mechanism includes a ring made from a heat shrinkable polymer that will heat shrink into a radial groove on the shaft. The heat shrinkable polymer of the ring has a release temperature wherein the ring shrinks in size when heated to a temperature above the release temperature. The ring has a pre-release size that is larger than the radial groove and a release size that is smaller than the outer circumference of the shaft. | 11-27-2008 |
| 20100092237 | SHAFT-GEAR CONNECTION - A shaft-gear connection and method for producing the connection which includes a shaft ( | 04-15-2010 |
| 20120195679 | ROTATION TRANSMITTING MEMBER - With the aim of providing a rotation transmitting member that suppresses the occurrence of abnormal noises, a rotation transmitting member includes a fitting portion ( | 08-02-2012 |
| 20120282018 | SHAFT-GEAR CONNECTION - A shaft-gear connection comprises a shaft and a shrunk-on gear that has an axial first section, attached by a first shrink-fit bond, and an axial second section, attached by a second shrink-fit bond. The second shrink-fit bond is greater than the first shrink-fit bond so that a greater maximum torque to be transmitted from the gear to the shaft by the second shrink-fit bond than by the first shrink-fit bond. An axial intermediate section, attached by a third shrink-fit bond, is located between the axial first section and the axial second section. Both a surface pressure and a maximum torque that can be transmitted by the third shrink-fit bond are greater than the surface pressure and the maximum torque that can be transmitted by the first shrink-fit bond, but are less than the surface pressure and the maximum torque that can be transmitted by the second shrink-fit bond. | 11-08-2012 |
| 20140234018 | CONNECTING MEMBER OF STRUCTURE - A bracket includes a cylindrical portion and a plate-shaped portion that are integrally formed. The cylindrical portion is provided at one end side of a blank along one direction and is provided with a slit extending over an entire length of the cylindrical portion in the one direction as a result of forming a portion at the one end side of the blank along the one direction into a cylindrical shape extending in the one direction. The plate-shaped portion is provided at the other end side of the blank along the one direction. The cylindrical portion of the bracket is inserted in the cylindrical body member formed of an aluminum alloy material, and the body member and the cylindrical portion are clinched by electromagnetic tube compression. | 08-21-2014 |
| 20150345504 | METHOD FOR FORMING A COATING MATRIX ON A SHAFT AND DISK ASSEMBLY FOR A TURBINE - A method for forming a coating matrix on a bore surface of a turbine disk wherein the coating matrix is applied at an interface between the disk and a turbine shaft. The coating matrix enhances thermal conductivity to increase heat transfer from the disk. The method includes providing a receiving surface on the bore surface. The receiving surface is then heated to melt the receiving surface. Next, at least one coating matrix layer is deposited on the receiving surface. The coating matrix layer includes a graphene layer. A pulsed laser system or a robot welding system may be used to melt the receiving section. | 12-03-2015 |
| 20160003280 | ASSEMBLIES INCLUDING SHAPE MEMORY ALLOY FITTINGS AND COMPOSITE STRUCTURAL MEMBERS - Provided are assemblies having composite structures interlocked with shape memory alloy structures and methods of fabricating such assemblies. Interlocking may involve inserting an interlocking protrusion of a shape memory alloy structure into an interlocking opening of a composite structure and heating at least this protrusion of the shape memory alloy structure to activate the alloy and change the shape of the protrusion. This shape change engages the protrusion in the opening such that the protrusion cannot be removed from the opening. The shape memory alloy structure may be specifically trained prior to forming an assembly using a combination of thermal cycling and deformation to achieve specific pre-activation and post-activation shapes. The pre-activation shape allows inserting the interlocking protrusion into the opening, while the post-activation shape engages the interlocking protrusion within the opening. As such, activation of the shape memory alloy interlocks the two structures. | 01-07-2016 |
