Embodiment Construction
[0029] In the following, preferred embodiments according to the present invention will be described in detail, said embodiments being shown in the drawings.
[0030] figure 2 is a cross-sectional view of a hermetic compressor according to the present invention; image 3 yes figure 2 Partial enlarged view of the oil supply device in ; and Figure 4 is along image 3 Cross-sectional view of line IV-IV in .
[0031] see figure 2 and image 3 According to the hermetic compressor of the present invention, the hermetic compressor includes the following components: a hermetic housing 101 forming a sealed space inside; a motor 103 installed inside said hermetic housing 101 to provide driving power; The driving power of the compression device 130 compresses the fluid; and the oil supply device 120 supplies lubricating oil to the inside of the sealed housing 101 to complete the lubrication and cooling functions.
[0032] The motor 103 includes a stator 104 around which an exci...

An oil supply apparatus for a hermetic compressor includes: a crankshaft coupled with a rotor of a motor so as to revolve together and having an oil flow path inside, a sleeve connected to a lower part of the crankshaft so as to revolve together with the crankshaft 107 in one body, a sucking member arranged to maintain a uniform interval with an inner circumference face of the sleeve so as to revolve in a direction opposite to that of the sleeve to carry out a suction of an oil, and a rotating force transferring means for supporting the sucking member so that the sucking member revolves together with the sleeve and receiving a rotating force of the sleeve so as to revolve the sucking member in a direction opposite to a revolving direction of the sleeve. The relative revolution speed between the sleeve and sucking member increases so as to increase the oil supply to the sliding and frictional parts, thereby enabling to improve a lubrication performance of the compressor. When the compressor generates vibration, the sucking member and sleeve vibrate with the same amplitude so as to maintain uniformly the gap between the sleeve and sucking member. Therefore, the present invention enables to improve a reliance of the oil supply.
Description
technical field [0001] The invention relates to an oil supply device of a hermetic compressor, more specifically, relates to an oil supply device of a hermetic compressor capable of increasing the amount of oil supplied and improving the lubricating performance of oil. Background technique [0002] Generally, a hermetic compressor, as a device for supplying compressed fluid, is mainly used in cooling systems, such as refrigerators, air conditioners, and the like. [0003] figure 1 It is a sectional view of a hermetic compressor in the prior art. [0004] see figure 1 , the hermetic compressor in the prior art comprises the following components: a hermetic casing 1 forming a sealed space inside; an electric motor 3 installed inside said hermetic casing 1 and used to provide driving power; A compression device 30 for compressing fluid; and an oil supply device 20 for supplying lubricating oil to the inside of the sealed housing 1 to complete lubrication and cooling.
