DESCRIPTION
PD ISO/TS 31657-2:2020
This standard PD ISO/TS 31657-2:2020 Plain bearings. Hydrodynamic plain journal bearings under steady-state conditions is classified in these ICS categories:
- 21.100.10 Plain bearings
This document specifies the characteristic values for selected two-, three- and four-lobe bearings.
The functions plotted and listed in table form below are required for the operationally safe design of hydrodynamic multi-lobed journal bearings according to ISO/TS 31657-1. They are based on the presumptions and boundary conditions indicated there and only apply to stationary operating states. The symbols used are explained in ISO/TS 31657-1; calculation examples are also included there.
