Definitions

  • the present invention relates to sliding material, particularly sliding material comprising fluorine plastic and binder resin for bonding the fluorine plastic, more particularly, the sliding material, which is suited for depositing on the sliding surface of a swash plate of the swash-plate compressor.
  • Fluorine plastic exhibits excellent low-friction property under the dry lubricating condition.
  • the fluorine plastic is blended with a solid lubricant such as MoS 2 , graphite and the like and they are bonded with base resin.
  • a sliding material which consists of from 50 to 73% by weight of at least one of polyamide resin and polyimide resin, from 3 to 15% by weight of polytetrafluoroethylene (PTFE) resin as solid lubricant, from 20 to 30% of molybdenum disulfide (MoS 2 ) and from 2 to 8% by weight of graphite, exhibits improved wear resistance and initial compatibility under the conditions of lubrication by graphite contained in the gray cast iron, low sliding speed of from 0.08 to 1 m/second, and relatively low load.
  • PTFE polytetrafluoroethylene
  • MoS 2 molybdenum disulfide
  • This material is appropriate for use as the surface layer of a piston skirt.
  • sliding material which contains from 10 to 40% by weight of calcined granular PTFE and from 3 to 40% by weight of graphite, the balance being a binder resin, i.e., polyimide and/or polyamide imide, exhibits improved sliding properties under the dry condition, and is appropriate as the sliding material of a wiper arm, which is operated under a low speed of 20 mm/s and relatively low load.
  • a binder resin i.e., polyimide and/or polyamide imide
  • the granular calcined PTFE is prepared by means of forming PTFE powder by suspension polymerization or emulsion polymerization, heating the resultant PTFE powder to melting temperature, i.e., calcining, and then pulverizing the calcined PTFE powder.
  • a swash-plate type compressor comprises the following members: cylinder block 1 ; valve plates 2 ; cylinder heads 3 ; a driving shaft 4 ; thrust bearings 5 ; radial bearings 6 ; a mechanical seal 7 ; a swash plate 8 ; a swash-plate chamber 10 , in which the swash plate 8 is mounted; a cylinder bore 11 ; a piston 12 ; balls 13 ; ports 15 formed through the valve plates 2 ; and ejecting chambers 16 ; ports (not shown) communicated with the ejecting chambers 16 ; the ejecting chambers (not shown); and suction chambers 21 .
  • the driving shaft 4 is rotary driven so as to rotate the swash plate 8 which is integral with the driving shaft 4 .
  • the piston 12 is reciprocated, thereby compressing cooling media within the cylinder bore 11 .
  • the compressed cooling media are ejected into the respective ejection chambers 16 A, 16 B via the ports 15 A, 15 B, respectively.
  • the compressed cooling media is then sucked into the cylinder bore 11 via the ports 17 , the ejection ports 19 , ports 20 , a pair of the suction chambers 21 A, 21 B, not-shown sucking valves, and ports 15 A formed through the valve plate 2 A.
  • the lubricating oil contained in the compressed cooling media is introduced into the swash-plate chamber 10 under a mist condition and is fed to the sliding portions of the swash plate 8 , the thrust bearings 5 and the like.
  • the prior art related to the surface treatment of a swash plate of the swash-plate type compressor includes the following.
  • a coating film consisting of a mixture of a solid lubricant and PEEK resin is formed on the swash plate.
  • the PTFE contained in the coating composition according to the prior art (2) mentioned above exhibits a low-friction effect at the sliding with shoes, under such a lubricating-oil poor sliding condition that a swash-plate type compressor mounted in a vehicle is started and driven to rotate and is lubricated only by the cooling media. Specifically, heat generation is suppressed by PTFE.
  • the swash-plate type compressor is operated under the sliding conditions of high speed and high load. In this case, the PTFE contained in the coating composition undergoes serious peeling wear so that the surface is drastically damaged and seizure occurs.
  • the surface treatment according to the prior art (1) mentioned above provides the coating film consisting only of metal. There is a possibility that the swash plate subjected to this surface treatment may seize with respect to the opposite member, i.e., the shoes, under poor lubricating-oil operating conditions.
  • the surface treatments according the prior arts (3), (4), (6), and (7) mentioned above provide a solid-lubricant coating film on the surface of metal.
  • This coating film may incur under such recent sliding conditions as high-speed rotation and high load a problem of peeling.
  • the surface coating of DLC according to the prior art (5) mentioned above may crack under the reciprocating load like the case of resin coating film.
  • the prior art (8) mentioned above provides a resin coating layer or a plating layer on the sintered metallic layer. Since the contact area between the resin coating layer and the sintered metal is larger than that of such layer and the non-sintered and hence non-porous metal, peeling of the resin coating layer is impaired. However, fundamentally, the peeling of the resin coating cannot be prevented, because the resin is of low strength and cannot withstand the load from the shoes.
  • an object of the present invention to improve the sliding properties of a sliding material which is subjected to high speed and high load and is used under varying sliding conditions from the lubricating-oil free condition to the lubricating-oil condition and vice versa.

  • FEP perfluoroethylene propylene tetrafluoroethylenen hexafluoropylene
  • ETFE ethylene-tetrafluoroethylene copolymer
  • PVdF polyvinyldenefluoride
  • ECTFE
  • the granular PTFE particles have smaller surface area than the flat PTFE particles.
  • the bonding strength of the former particles with the binder is, therefore, lower than that of the latter particles.
  • the former particles are, therefore, liable to separate from the binder, so that peeling of PTFE is induced.
  • the sliding material comprising the flat PTFE particles bonded with the binder has improved compatibility such that fluid lubrication can be realized on the surface of the sliding material.
  • PTFE exhibits low-friction property independently upon the shape of PTFE particles.
  • the friction between the PTFE-containing sliding material and a shoe is, therefore low during sliding.
  • the extremely thin surface of the PTFE particles having a thickness of few atom-layers is subject to cleavage. This process takes place even under extremely weak external force, so that satisfactorily low friction is realized.
  • FIG. 1 is a cross-sectional drawing of a swash-plate type compressor according to an example.
  • FIG. 2 is a graph showing a relationship between the average aspect ratio of the PTFE particles and the seizure time of the PTFE based sliding material.
  • the average aspect ratio in a range of from 1 to 5 is shown in a larger scale than that of from 5 to 10 and 10 to 15.
  • FIG. 3 is a schematic drawing of a sliding layer, which contains flat PTFE, graphite and MoS 2 .
  • the granular PTFE particles can be flattened by means of imparting strong shear blending.
  • a bead mill blender which can perform strong shear blending, was used to prepare the solid-lubricant coating-mixture, which may be referred to as the paint.
  • the average aspect ratio of PTFE particles and the blending time of the paint were investigated.
  • the seizure time in dependent on the average aspect ratio was also investigated.
  • composition of the paint was 60% by volume of PAI, 20% by volume of PTFE, and 20% by volume of graphite for every blended mixture with the varied average aspect ratio.
  • the testing condition was as follows.
  • the seizure time increases with increase in the average aspect ratio up to approximately 0.2.
  • the seizure time then decreases because the strength of PTFE decreases excessively due to flattening.
  • the average aspect ratio of the PTFE particles is limited in a range of from 1.5 to 10 according to the present invention.
  • a preferable average aspect ratio is from 2 to 5.
  • the PTFE particles present on a surface area of 1 mm ⁇ 20 ⁇ m were measured in terms of the ratio of long diameter/short diameter, and the average value of the measured values was calculated as the average aspect ratio.
  • the binder is selected from a heat-resistant resin and is preferably at least one selected from polyamide imide and polyimide.
