Abstract
An eccentric slider for a crankshaft, a scroll compressor, and a temperature control device are provided. The eccentric slider has a slider body. An assembly hole is formed in the slider body. The assembly hole allows insertion of an eccentric shaft segment of the crankshaft. An outer peripheral wall surface of the slider body has a bearing surface and a non-bearing surface opposite to the bearing surface. The bearing surface drives an orbiting scroll. A hollow portion is formed on the non-bearing surface. The hollow portion accommodates an oil.
Claims15
An eccentric slider for a crankshaft, the eccentric slider comprising:
- a slider body comprising:
- a bearing surface configured to drive an orbiting scroll;
- and
- at least one non-bearing surface opposite the bearing surface,
- wherein:
- the slider body forms:
- an assembly hole configured to allow for an insertion of an eccentric shaft segment of the crankshaft;
- and
- a hollow portion on the non-bearing surface configured to accommodate an oil, wherein the hollow portion is a plurality of through grooves extending in an axial direction of the slider body and spaced apart from each other;
- and
- an angle formed between a plane passing through one of two sides of the hollow portion and a central axis of the slider body and a plane passing through another side of the two sides of the hollow portion and the central axis of the slider body ranges from 60° to 120°.
A scroll compressor comprising:
- a crankshaft comprising:
- an eccentric shaft segment forming an oil passage that penetrates the eccentric shaft segment and extends in an axial direction of the crankshaft;
- an orbiting scroll forming a mounting portion;
- and
- an eccentric slider mounted between the eccentric shaft segment of the crankshaft and the mounting portion of the orbiting scroll, the eccentric slider comprising:
- a slider body comprising:
- a bearing surface configured to drive the orbiting scroll;
- and
- at least one non-bearing surface opposite the bearing surface,
- wherein:
- the slider body forms:
- an assembly hole interfacing with the eccentric shaft segment of the crankshaft;
- and
- a hollow portion on the non-bearing surface configured to accommodate an oil, wherein the hollow portion is a plurality of through grooves extending in an axial direction of the slider body and spaced apart from each other;
- and
- an angle formed between a plane passing through one of two sides of the hollow portion and a central axis of the slider body and a plane passing through another side of the two sides of the hollow portion and the central axis of the slider body ranges from 60° to 120°.
An eccentric slider for a crankshaft, the eccentric slider comprising:
- a slider body comprising:
- a bearing surface configured to drive an orbiting scroll;
- and
- at least one non-bearing surface disposed opposite the bearing surface and comprising a hollow side surface,
- wherein:
- the slider body forms an assembly hole configured to allow for an insertion of an eccentric shaft segment of the crankshaft;
- the non-bearing surface forms a hollow portion configured to accommodate an oil, wherein the hollow portion is a plurality of through grooves extending in an axial direction of the slider body and spaced apart from each other;
- and
- the hollow side surface is convex away from a central axis of the slider body.
