This document specifies methods and formulae for evaluating the risk of scuffing, based on Blok's contact temperature concept. The fundamental concept is applicable to all machine elements with moving contact zones. The flash temperature formulae are valid for a band-shaped or approximately...
ISO/TS 6336-20:2017 specifies methods and formulae for evaluating the risk of scuffing, based on Blok's contact temperature concept. The fundamental concept is applicable to all machine elements with moving contact zones. The flash temperature formulae are valid for a band-shaped or...
This document specifies a calculation method for oil-lubricated hydrodynamic plain bearings with complete separation of the thrust collar and tilting pad thrust bearing surfaces by a film of lubricant. This document applies to plain thrust bearings with tilting-type sliding blocks (tilting pads),...
1.1 This specification covers two classes of round and shaped quenched and tempered steel spring wire intended especially for the manufacture of mechanical springs and wire forms. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as...
1.1 This specification covers two classes of commercial quality round and shaped quenched and tempered steel spring wire intended especially for the manufacture of mechanical springs and wire forms. The quality level is lower than specialty spring quality (Specification...
This part of ISO 898 specifies mechanical and physical properties of flat washers, designed to be used in bolted joints in combination with bolts, screws, studs and nuts with a specified property class in accordance with ISO 898-1 and ISO 898-2. Washers that conform to the requirements of this part...
