Title: Differential gear assembly
Inventor: WHITE STANLEY B
IPC: F16H48/285
Filed: 1992-11-25
Abstract: A limited slip differential gear assembly has a rotating housing (1) containing meshing spur gears (16, 17) each turning a gear element (e.g. 23) which is externally helically toothed. Each gear element (e.g. 23) meshes with its own externally helically-toothed gear member (e.g. 30) which has a larger diameter and drives one of two output shafts (26, 27) between which differential movement is to take place. The meshing helical gear teeth have the characteristic that the efficiency of drive transmission in opposite directions is different and this provides the limited slip. As the axes of rotation of all rotating parts of the assembly are parallel, reduced constructional and operating costs are claimed.

IPC: G02B6/42
Filed: 1993-07-30
Abstract: ABSTRACT OF THE DISCLOSURE    In one embodiment, the present invention includes a method of increasing the attachment bond strength between a first and second object comprising respective first and second materials.  Each of the first and second materials has a respective first coefficient of thermal expansion at an assembly temperature, and a second coefficient of thermal expansion at an operational temperature.  The method has various steps (Fig. 4).  An attachment surface of the first material is configured to be nonplanar (Fig. 3a, 36, 37).  The second material is brought to a contact point with the attachment surface of the first material (Fig. 3b, 46).   The first and second materials are heated at the contact point to the assembly temperature wherein at least one of the materials is caused to flow in response to the heat.  Finally, the first and second materials are brought to the operational temperature, wherein at least one of the first and second materials is placed in a compressive state at the contact point due to the relative change in size of at least of the first and second materials as compared with the change in size of the other of the first and second materials.     In a second and third embodiment, the present invention pertains to a method of sealing an end of a sleeve having an axial channel and a fiber extending through the axial channel and outward from the sleeve end.
