Title: Friction bush preventing the direct contact of a lipped sealing ring on a revolving shaft, and a device for locking it on the shaft
IPC: F16J15/32
Filed: 1986-01-27
Abstract: Friction bush 1 for a lipped sealing ring e, which can be fitted to a revolving shaft a. The invention relates to a type of friction bush 1 for a lipped sealing ring e, provided with a device capable of locking it axially and rotationally in both directions on a revolving shaft a. One of the ends of the bush 1 comprises a reduction in thickness 2. In this reduction, a transverse tab 4 is produced by machining from a cutout 3 and a narrow slit 5. Thus, the axial locking in both directions is ensured, as soon as the transverse tab 4 enters a groove 7 made in the revolving shaft a. The rotational locking in both directions is ensured by an O-ring 6 situated in a groove made in the revolving shaft a. The friction bush 1 according to the invention is intended to prevent the direct link between the lipped sealing ring e and the revolving shaft a, which direct link is highly ill-advised, by providing a very simple, low-bulk and very economical solution.

Patent FR-2598226-A1 (FR)
Inventor: CHERBUY JEAN
IPC: G01L1/22
Filed: 1986-04-30
Abstract: A resistance-gauge force transducer comprises a resilient bar having one end adapted to be fixed to a stationary support and the other end subjected to the force to be measured. The bar carries two pairs of resistance gauges symmetrically disposed on both sides of the center of gravity of the bar. The direction of the lines of current of a gauge of one pair is parallel to the bar axis and perpendicular to that of the other gauge of the same pair. The gauges are electrically connected together so as to form a wheatstone bridge delivering a signal which is a function of the force applied to the end of the bar. The two gauges of one pair are adjacent and connected to each other in the wheatstone bridge. This arrangement renders the force transducer insensitive to thermal variations.
