Abstract
A scroll compressor includes a plurality of fixing protrusions that are provided spaced apart from each other in a key that constitutes an Oldham ring, and an orbiting scroll, to which the key is coupled, or a ring body of the Oldham ring may be provided with a plurality of fixing grooves which are spaced part from each other and into which the plurality of fixing protrusions are respectively inserted and fixed.
Claims14
A scroll compressor comprising:
- an orbiting scroll, as at least one scroll of a plurality of scrolls engaged with each other, coupled to a rotational shaft to perform an orbiting motion;
- and
- an Oldham ring slidably coupled to the orbiting scroll to induce the orbiting motion of the orbiting scroll,
- wherein a key groove is formed in one of the orbiting scroll and the Oldham ring, and a key is disposed on another one to be slidably inserted into the key groove,
- wherein the key comprises a plurality of fixing protrusions spaced apart from each other,
- wherein the orbiting scroll or the Oldham ring comprises a plurality of fixing grooves which are spaced apart from each other and in which the plurality of fixing protrusions are fixedly inserted, and
- wherein the plurality of fixing protrusions are connected into an annular shape and the plurality of fixing grooves are connected into an annular shape.
