摘要:
A spinning ring, in which a ring flange portion (101) making a track permitting a ring traveller to run thereon is divided into an inner flange (104) and an outer flange (106), the inner flange (104) is continuously formed from a sheet steel, the outer flange (106) is formed together and integral with a ring neck portion (109) and a mount portion (102) by cutting, the inner flange (104) and the outer flange (106) are secured to each other by a securing means, and a ring flange portion (101) is provided in an upper portion of the spinning ring (100). The spinning ring enables enhancing the ring flange portion in accuracy and wear resistance, and preventing fine vibrations of the ring flange portion from causing abnormal wear of and shortening of service life of a ring traveller and the ring flange portion and frequent yarn breakage leading to reduction in productivity and falling-off of the ring flange portion due to shock.
摘要:
A ring (1) for use in spinning machineries such as ring spinning machines and twisting machines, makes it possible to use at a high spindle revolutionary speed of 20,000 r.p.m. The ring comprising a ring flange (5), a neck part (4), a collar (3) and a trunk part (2) having ring fitting part is provided at the surface of the slide contact part of at least the ring traveller with a composite plated layer (6) of nickel and phosphorous alloy (7) containing hard fine grains (8). The ring is further treated with heating and polishing processes to increase hardness and smoothness of the surface thereby to improve anti-wearing properties and heat-proof properties.
