Abstract:
The present invention provides a swash plate, for a swash plate compressor, which is excellent in a resistance to the occurrence of seizing in a condition where an extreme pressure is generated owing to local contact between the swash plate and a shoe which slides thereon and in a condition where lubricating oil is depleted, capable of preventing cavitation-caused erosion of a resin film when the swash plate is operated at a high surface pressure and a high speed in the presence of the lubricating oil and the swash plate compressor having the swash plate. A swash plate (3) for a swash plate compressor is so constructed that inside a housing (1) where a refrigerant is present, the refrigerant is compressed and expanded by converting a rotational motion of the swash plate (3) mounted perpendicularly and obliquely on a rotational shaft (2) by directly fixing the swash plate (3) to the rotational shaft (2) or indirectly fixing the swash plate (3) to the rotational shaft (2) through a coupling member into a reciprocating motion of a piston (5) through a shoe (4) which slides on the swash plate (3) into a reciprocating motion of a piston (5) through a shoe (4) which slides on the swash plate (3). A resin film containing 25 to 70 parts by weight of fluororesin and 1 to 20 parts by weight of graphite for 100 parts by weight of matrix resin and having a tensile shear adhesive strength not less than 25 MPa is formed on a sliding contact surface of the swash plate (3) on which the shoe (4) slides.
Abstract:
The invention concerns the field of polymer chemistry and relates to modified PTFE solid lubricants which can be used as additives, for example. The problem addressed by the present invention is to provide modified PTFE solid lubricants which are easier to handle and dispense. The problem is solved by a method, in which PTFE micro-powder, comprising groups which are at least functional and/or can be thermally activated, is mixed with at least one low molecular weight and/or oligomer compound, comprising at least one NH group that is reactive or thermally reactable and/or can be activated by a catalyst, in a ratio of 100 g PTFE micro-powder to

It is an object of the invention to provide a sliding material composition and a sliding member capable of achieving low friction property at starting time and during sliding and also being excellent in abrasion resistance, especially when a counterpart sliding member is a rubber-based material. The invention relates to a sliding material composition for use in a sliding member whose counterpart sliding member is configured of rubber, the sliding material composition comprising a binder resin, 5 to 25 vol% of an Nω-monoacyl basic amino acid, 5 to 25 vol% of molybdenum disulfide, and 5 to 20 vol% of polytetrafluoroethylene.
Abstract:
The invention relates to the field of chemistry and concerns long-term stable oil PTFE dispersions, as can be used for example in gears or bearings, and a method for their production. The aim of the present invention is therefore specifying long-term stable oil PTFE dispersion, and a simple and cost-effective method for its production. This task is solved by an oil PTFE dispersion comprising PTFE particles and a singly or multiply olefinically unsaturated oil, wherein molecules of the olefinically unsaturated oil an PTFE (primary) particle surfaces are coupled covalently/chemically by radical reactions, and wherein there is permanent charge separation between the PTFE particle surfaces and the coupled oil molecules and a fine dispersing of the PTFE particles in the oil or oil mixture. This task is further solved by a method in which modified PTFE (emulsion) polymers with persistent perfluor(peroxy) radical are mixed in with olefinically unsaturated oil, after which the modified PTFE (emulsion)polymers undergo mechanical stress.
