摘要： A scroll compressor having an extended life due to the support structure for the orbiting scroll, even when using a chlorine-free substitution refrigerant. The support structure includes an Oldham ring for supporting an orbiting scroll so as to allow the orbiting scroll more orbiting motion without rotating about a fixing scroll. The Oldham ring is formed of a different material from both a fixing member and the orbiting scroll. Hence, if a boundary lubrication state occurs in mutually sliding parts, only sliding between different materials occurs, and mutual adhesion in the portion of the boundary lubrication state is avoided. As a result, the shortening of the life due to the wearing of the support structure of the orbiting scroll is prevented.

摘要： A compressor for a refrigeration machine is provided without any problems of reduction in the life of a thrust bearing structure even when a substitutive coolant not containing any chlorine is used. In the compressor for a refrigeration machine having a thrust bearing made of steel for supporting a thrust load applied to a drive shaft, a thrust bearing surface made of a material different from that of the drive shaft is formed in the thrust bearing by means of a surface treatment. Alternatively a washer defining the thrust bearing surface may be surface treated to provide a material different from that of the drive shaft. The washer may also be made of a material different from that of the drive shaft. According to the the present invention, even when a boundary lubricating state is produced between the drive shaft and the thrust bearing surface sticking is prevented. As a result, the life of the thrust bearing structure of the drive shaft can be made longer and a problem of reduction in the life of the thrust bearing structure can be avoided even when a substitutive coolant not containing any chlorine is utilized.
摘要翻译：提供一种用于制冷机的压缩机，即使使用不含氯的替代冷却剂，也不会产生推力轴承结构的寿命降低的问题。在具有用于支撑施加到驱动轴上的推力负载的由钢构成的推力轴承的制冷机的压缩机中，由推力轴承形成的与驱动轴不同的推力轴承表面形成在推力轴承中表面处理。或者，限定止推轴承表面的垫圈可以被表面处理以提供与驱动轴不同的材料。垫圈也可以由与驱动轴不同的材料制成。根据本发明，即使在驱动轴与推力轴承面之间产生边界润滑状态，也能够防止粘着。结果，即使使用不含氯的替代冷却剂，驱动轴的推力轴承结构的寿命也可以更长，并且即使使用不含氯的替代冷却剂，也能够避免推力轴承结构的使用寿命的问题。

摘要： A cleaning device includes a fixing portion provided on a frame, a cleaning member, and an accommodating portion. The cleaning member includes a blade portion contacted to an image bearing member (drum) and a supporting member. The supporting member includes one end portion where the blade portion is provided, another end portion including a portion-to-be-fixed for being fixed at the fixing portion, and a bent portion between the one end portion and the other end portion in a side remote from a surface of the drum toward an outside with respect to a line connecting the portion-to-be-fixed and a contact portion where the blade portion is contacted to the drum. The portion-to-be-fixed is provided downstream of the contact portion with respect to movement direction of the drum. Between the frame and the other end portion, a gap for permitting elastic deformation of the other end portion is provided.
