Abstract
A scroll compressor is provided that may include a fixed scroll having a fixed wrap, an orbiting scroll engaged with the fixed wrap to define a compression chamber, a rotation shaft having a shaft portion eccentrically located with respect to the orbiting scroll, a pin portion located at an end of the shaft portion and having a diameter smaller than a diameter of the shaft portion, and a bearing located at an end of the pin portion, and a drive that drives the rotation shaft. The pin portion may be inserted through one of the fixed scroll or the orbiting scroll, and the orbiting scroll may be rotatably coupled to the bearing.
Claims22
A scroll compressor, comprising:
- a fixed scroll having a fixed wrap formed at an upper surface of a disk;
- an orbiting scroll disposed on top of and engaged with the fixed wrap to define a plurality, of compression chambers;
- an upper frame disposed above the orbiting scroll;
- a rotational shaft comprising a shaft portion eccentrically located with respect to the orbiting scroll, a pin portion located at an end of the shaft portion and having a diameter smaller than a diameter of the shaft portion, and a bearing located at an end of the pin portion;
- and
- a drive that drives the rotation rotational shaft, wherein the pin portion is inserted through the orbiting fixed scroll, and the orbiting scroll is rotatably coupled to the bearing, wherein the pin portion is coaxially disposed with respect to the shaft portion, wherein a diameter of a shaft insertion hole of the disk is smaller than a diameter of the shaft portion, wherein the end of the shaft portion is disposed so as to face a lower surface of the disk, and the pin portion is inserted through the shaft insertion hole, and wherein the bearing is eccentrically disposed with respect to the pin portion.
A scroll compressor, comprising:
- a fixed scroll having a fixed wrap formed at an upper surface of a disk;
- an orbiting scroll engaged with the fixed wrap to define a plurality of compression chambers;
- a high pressure chamber disposed above the fixed scroll;
- a rotational shaft having a shaft portion eccentrically located with respect to the orbiting scroll, a pin portion located at an end of the shaft portion and having a diameter smaller than a diameter of the shaft portion, and a bearing located at an end of the pin portion;
- and
- a drive that drives the rotational shaft, wherein the pin portion is inserted through the fixed scroll, and the orbiting scroll is rotatably coupled to the bearing, wherein the pin portion is coaxially disposed with respect to the shaft portion, wherein a diameter of a shaft insertion hole of the disk is smaller than a diameter of the shaft portion, wherein the end of the shaft portion is disposed so as to face a lower surface of the disk, and the pin portion is inserted through the shaft insertion hole, and wherein the bearing is eccentrically disposed with respect to the pin portion.
