摘要:
A wrap of an orbiting scroll member and a wrap of a fixed scroll member are each provided with a non-rigid surface coating layer having a predetermined thickness. An orbiting radius varying mechanism is provided between a driving shaft and the orbiting scroll member, thereby gradually increasing the orbiting radius of the orbiting scroll member at the initial stage of running, and thus positively allowing the surface coating layers to wear by rubbing against each other. A stopper mechanism is provided between the driving shaft and the orbiting scroll member to regulate the rotation angle of a variable crank relative to the driving shaft to a predetermined rotation angle, thereby preventing the surface coating layers from being excessively worn as the orbiting radius of the orbiting scroll member increases.

In the scroll-type fluidic machine according to the present invention, a slider is slidably disposed between a casing and a rear surface of a orbiting scroll member, and a sliding movement of the slider relative to the casing and the orbiting scroll member is regulated to two (X-axis and Y-axis) directions by means of X-axis and Y-axis guides. Balls received in through holes of the slider are formed from material harder than that of the slider and are rollingly contacted with a slide surface of a flange portion of the casing and a slide surface of a rear plate of the orbiting scroll member. The through holes are filled with grease. The balls are adapted to roll smoothly, thereby greatly decreasing frictional resistance between surfaces of the slider and the slide surfaces of the casing and the orbiting scroll member.

A scroll fluid machine comprises a fixed-side member including a cylindrical casing and a fixed scroll fixed to the casing, and an orbiting scroll and a plurality of ball coupling devices provided between the fixed-side member and the orbiting scroll to prevent self-rotation of the orbiting scroll on its axis and receive a thrust load between the fixed-side member and the orbiting scroll. Each of the ball coupling devices comprises a first ball coupling mechanism for supporting the thrust load generated between the fixed-side member and the orbiting scroll and a second ball coupling mechanism disposed with a space from the first ball coupling mechanism to prevent the self-rotation of the orbiting scroll.

Inner peripheral projections are provided on the inner peripheral surface of a wrap portion of an orbiting scroll member, and outer peripheral projections are provided on the outer peripheral surface of the wrap portion. The inner and outer peripheral projections each have an approximately triangular transverse sectional configuration defined by a narrow top of the projection and a pair of concavely arcuate surfaces extending with a wide overall width so that the projections can prevent stress concentration with the concavely arcuate surfaces to increase the mechanical strength and can be readily machined by using a tool, e.g. an end mill. When contacting the mating wrap portion, the narrow tops of the projections are readily crushed or worn. Therefore, the tops of the projections can become fit to the wrap portion without strongly contacting it many times.

A scroll fluid machine includes: a casing; a fixed scroll having an end plate, a spiral wrap part provided on the end plate, and a flange provided outside the wrap part and fitted to the casing; and an orbiting scroll having an end plate and a spiral wrap part provided on the end plate with a plurality of compression chambers formed in a space up to the wrap part of the fixed scroll, which is provided to perform an orbiting motion, wherein the flange is provided with a deformation absorbing part which absorbs deformation due to thermal expansion of the end plate. The scroll fluid machine is improved in reliability while the compression efficiency is maintained by preventing the fixed scroll and the orbiting scroll from coming into contact with each other without increasing a clearance between the wrap parts of both scrolls.
摘要:
A scroll fluid machine includes a fixed scroll member having an end plate which is formed such that a central portion of the end plate which corresponds approximately to 1.5 to 2 turns of a wrap portion from its spiral starting end (innermost end) is a thick-walled portion having a relatively large plate thickness, and an outer peripheral portion of the end plate which lies radially outside the thick-walled portion is a thin-walled portion. The thickness of the thick-walled portion is set to be about 1.4 to 1.6 times the thickness of the thin-walled portion. By reducing thermal resistance at the thick-walled portion of the end plate, heat from compression chambers are conducted to radiating fins, thereby suppressing the transfer of the heat to the thin-walled portion.

A scroll-type fluid machine reduces intrusion of abrasion powders, generated by sliding of a conductor causing an orbiting scroll side and a fixed scroll side to be conducted, into a compression chamber, and improves reliability of a compressor. The scroll-type machine includes a casing, a fixed scroll having a flange surface attached to the casing, and a wrap portion provided at an end plate, an orbiting scroll having a wrap portion provided at the end plate, and provided in an opposed relationship with the fixed scroll, a drive shaft connected through a crank portion to the orbiting scroll, an orbiting bearing, a face seal portion arranged between the orbiting scroll and the fixed scroll, a cooling fan, and an orbiting scroll side conductive brush.

The production of semiconductor devices manufactured through a plurality of manufacturing sites is unitarily managed and an appropriate production plan is instructed. A computer projects a production plan of an entire company based on various information. The production plan is provided to each manufacturing site as a production instruction and provided to each business person or customer as a storing reply or an order accepting period reply. If the projected production plan (possible production volume) does not coincide with a production plan (necessary production volume), parameters obtained by correcting production allocation, production capability, lead time, yield and the like are re-input from a parameter input terminal. Based on the corrected parameters, the computer re-projects the production plan and projects an optimum production plan.
