4244 results about "Washer" patented technology

A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). Washers often have an outer diameter (OD) about twice their inner diameter (ID), but this can vary quite widely.

Bone anchor and deployment device therefor

A rivet-like bone anchor has a floating washer at its head that can adapt to an angled bone surface and, thereby, better secure a tissue thereto. The anchor includes a rivet, an expandable sleeve, and a washer. The rivet includes a head and an elongate body having proximal and distal ends, the head being mounted on the proximal end of the elongate body. The expandable sleeve has an inner bore adapted to receive the rivet body. The washer “floats” at a proximal end of the sleeve. As the rivet is inserted into sleeve, the sleeve expands into an interference fit with the bone. The head of the rivet, moreover, forces the floating washer into contact with the tissue at an angle that conforms to that of the underlying bone surface. A deployment tool permits the anchor to be deployed without application of unnecessary counterforce. The tool includes an outer tube, the distal end of which can hold the anchor housing, e.g., via a screw fit. A rod, which is slidably disposed within the bore of the tube, can be used to push the rivet into the expandable sleeve so that the sleeve expands into the bone, so that the floating washer is forced into position against the bone surface, and so that anchor is broken away from the housing. This can be effected, for example, by squeezing the distal ends of the outer tube and the rod together, e.g., in the manner that the end of a syringe is squeezed.

Bearing washer

The invention discloses a bearing washer, which comprises a main body workbench, a washing chamber arranged on the main body workbench, a spraying pump and a drive motor, wherein the main body workbench is provided with an inlet-outlet path of the washing chamber; the inlet-outlet path is provided with a feed-discharge trolley; the inlet-outlet path is connected with an inlet-outlet cylinder; an upper spraying pipe is arranged at the top position in the washing chamber, and a lower spraying pipe is arranged at the bottom position in the washing chamber; the feed-discharge trolley is provided with an inner stationary fixture, an outer stationary fixture and an upper drive carriage, and the inner and outer stationary fixtures can adjust and clamp a large-size bearing; a rotary spindle, which can be jointed with the centre of the inner stationary fixture, is arranged at the top position in the washing chamber; and the rotary spindle is connected with the drive motor. The bearing washer has the advantages of reducing intermediate links, automatically completing the whole process of product washing, effectively washing dead corners in the products, greatly improving the cleanness of the product, along with high automation, high washing efficiency, low operation and labor intensity, quick, convenient and flexible clamping and fixing operation and complete washing.
