Title: Production of pulley for multiple V-belt drive - by forming grooves with contoured rollers in sequence of operations
Inventor: FRIESE UDO
IPC: B21D53/26
Filed: 1990-04-26
Abstract: The invention concerns a method of producing a pulley for a multiple V-belt drive. A blank in the form of a disc (3) with a central hub and a thick rim is first produced. A shallow groove is formed in the rim by rotating the blank and pressing a contoured roller radially against the rim so that the two flanges (4, 4a) are formed. The blank is subjected to a second forming operation which produces a rim with raised edges and a flat central region. A third operation increase the radial height of the flanges and a fourth operation produces the V grooves (5). USE - V-belt pulleys.

Patent DE-4103116-A1 (DE)
Inventor: KUEBERT MICHAEL DIPL ING DR
IPC: F16C33/12
Filed: 1991-02-01
Abstract: Highly wear-resistant sliding bearings with good sliding properties are difficult to manufacture by electrochemical deposition of the sliding alloy, because the corresponding electrolyte solutions are unstable. Conventional sliding alloys are also too hard for a run-in period and wear too rapidly when used in accordance with specifications. The new sliding layer is simple to manufacture and has an extremely favorable run-in period. The soft constituent of the sliding layer is present in a concentration which decreases along a concentration gradient perpendicular to the effective surface of the sliding layer as the distance from the effective surface increases. The sliding layer is particularly suitable for use as a lead-tin-copper alloy in a multilayered bearing.
