Because it has properties such as electrical properties and hot water resistance, it is used in a number of applications including the electrical and electronic fields, the mechanical field, the automobile field, the aircraft field, and the medical food industry field. In addition to the above-mentioned properties, compositions containing aromatic polysulfone and a fluorocarbon polymer, preferably polytetrafluoroethylene, have self-lubricating properties, and therefore have various applications in the above-mentioned fields. used in

となどの特性が要求される。However, in order to use a composition consisting of aromatic polysulfone and a fluorocarbon polymer in oil-free bearings, etc. 11% property is insufficient. Generally, in order to use plastic as a sliding material such as a bearing, in addition to having a low and stable friction coefficient, it must also have high limit P and v values, and a low wear coefficient that indicates wear resistance properties. characteristics are required.

しなから限界PV値内での使用条件下でも、必す少しず
つ摩耗は進行するので寿命を考慮しなければならない。The PV value is the product of the pressure P applied to the bearing and the sliding speed ■, and the limit PV value is the generation of frictional heat at the contact end surface with the bearing, resulting in a significant increase in T+, -; This is the limit PV value at which plastic softens, melts, chemically decomposes, etc., and normal frictional motion cannot continue. However, even under usage conditions within the limit PV value, wear inevitably progresses little by little, so the service life must be taken into consideration.
このために軸受設計の資料としては、限界PV値より摩
耗係数の方が重要であり、限界PV値は軸受などの使用
限界の1つの目安として使われている。For this reason, as a material for bearing design, the wear coefficient is more important than the limit PV value, and the limit PV value is used as a guideline for the usage limit of bearings, etc.
ところで賑粍係数には一般的に次式で表わされる。By the way, the buzz coefficient is generally expressed by the following formula.

In other words, even the same PV value varies depending on high pressure and low speed conditions and low pressure and high speed conditions.

AS Percules Co., Ltd. was mixed in a Henschel mixer to the composition ratio shown in Table 1, and then mixed in a twin-screw extruder (
Ikegai Tekko PCM-80) was used to set the temperature at the center of the cylinder to 3.
The temperature was set at 10 to 880°C, and extrusion granulation was performed to obtain pellets. Using a J, OZ injection molding machine (Neomat 47/28 manufactured by Sumitomo M Machinery), the temperature at the center of the cylinder was set at 840 to 370°C, and bending test pieces and wear links (outer diameter 25.6 degrees, inner diameter 20 layers, height 15U) was molded. The bending properties were measured from the bending test piece, and the pressure P = 5 was measured using a precious wood type abrasion tester from the wear ring.
The mating material is 8KH-2 under the conditions of K17cm2 and speed 40ψ.
