摘要： The object of the present invention is to improve sealing performance of a seal under a specific environment. The seal is arranged in an annular space A in which a rotary shaft 1 and a housing 2 face each other, and partitions the annular space in axial direction into a vacuum space B and an atmospheric pressure space C. The seal is constituted such that a main lip 6 of the seal has an axial contact width W0 with which the main lip slides on and contacts with the rotary shaft 1 and which is set to be equal to or larger than an axial contact width W1 necessary to secure minimum sealing performance with respect to a sealed portion and equal to or smaller than an axial contact width W2 with which sliding resistance against the rotary shaft becomes a permissible upper limit, to thereby prevent the axial contact width W0 from influencing rotation characteristics with respect to the rotary member and to allow securing required sealing performance.
摘要翻译：本发明的目的是提高密封在特定环境下的密封性能。密封件布置在旋转轴1和壳体2彼此面对的环形空间A中，并且将环形空间沿轴向分隔成真空空间B和大气压力空间C.密封件构成为密封件的主唇缘6具有轴向接触宽度W0，主唇部与主旋转轴1滑动并与旋转轴1接触，并且被设定为等于或大于确保最小密封性能所需的轴向接触宽度W1 到等于或小于轴向接触宽度W2的轴向接触宽度W2，通过该轴向接触宽度W2与旋转轴的滑动阻力成为允许上限，从而防止轴向接触宽度W0相对于旋转构件影响旋转特性，并且允许确保所需的密封性能。

摘要： A process for forming a lubricating film on a direct acting bearing includes the steps of forming a liquid film on at least the rolling and sliding portions of the direct acting bearing by using a solution prepared by diluting a fluorine-containing polymer in a solvent. The liquid film is then cured to form a solid film of a fluorine-containing polyurethane high molecular compound on the direct acting bearing.

摘要： A traction drive spindle device includes an input shaft connectable to a drive main shaft for rotation therewith. A hollow holder shaft is connected to an output end of the input shaft in coaxial relation thereto, the hollow holder shaft having a plurality of planetary rollers mounted thereon intermediate opposite ends of the holder shaft. A high-speed spindle is rotatably received in a bore of the hollow holder shaft, the high-speed spindle having an inner end portion which is received in the bore and serves as a sun shaft disposed in rolling contact with the planetary rollers. A housing is mounted on the outer periphery of the holder shaft through a first ball-and-roller bearing so as to be rotatable relative to the holder shaft, the housing having a fixed ring fixed to an inner periphery thereof. The planetary rollers are disposed in rolling contact with the fixed ring. A second ball-and-roller bearing is interposed between the holder shaft and the high-speed spindle. Only the balls and both the balls and the rollers of the second ball-and-roller bearing are made of ceramics.

摘要： A rolling bearing is used for supporting a rocking mechanism or a rotating mechanism, and a film comprising a fluorine-containing polymer having a functional group(s) under a fluidizied state or a film comprising a fluorine-containing polyurethane compound under a solid state is formed on at least the track surface of the rolling bearing. Since this film does not contain ions for uniformly dispersing a thickner having non uniform particle sizes such as fluorine based grease of the prior art, breakage of the film between a rolling element and a race is not likely to occur, and wear of a rolling element race resulting from the direct contact between them due to breakage of the film can be reduced. When this film is tha same kind of a film as a protective film of the surface of an information recording disk, dust generating components of the film are the same kind of components as those of the protective film, and information recording/reproduction of the information recording disk is not impeded.

摘要： A solid film of a fluorine-containing polyurethane polymer is formed on at least one of the constituent elements (inner and outer rings, rolling member and retainer) of a rolling-contact bearing. The molecules of the solid film of the fluorine-containing polyurethane polymer have urethane bonds, and form a three-dimensional reticular structure. Therefore, the film is unlikely to separate, peel off or wear. The occurrence of the dust can be restricted, and lubrication property can be improved.
