Abstract

An oil supply device for a hermetic compressor, which comprises: a crankshaft connected with the motor rotor so as to rotate together with it and having a lubricating oil passage inside; a sleeve connected with the lower part of the crankshaft for It is integrated with the crankshaft and rotates together; an oil-absorbing member arranged to maintain a uniform interval with the inner peripheral surface of the above-mentioned sleeve, which rotates in the direction opposite to the rotation direction of the sleeve to complete the oil-absorbing work; and an oil-absorbing member for supporting the above-mentioned oil-absorbing member The rotation force transmission device of the component is used to make the oil-absorbing component rotate together with the sleeve, and the device receives the rotational force from the sleeve so that the oil-absorbing component rotates in the direction opposite to the direction in which the sleeve rotates. The increased relative rotational speed between the sleeve and the oil absorbing member increases the amount of oil supplied to the sliding parts and friction parts, thereby improving the lubricating performance of the compressor. When the compressor vibrates, the oil-absorbing member and the sleeve vibrate with the same amplitude, so that the gap between the sleeve and the oil-absorbing member can be kept uniform. Therefore, the present invention can improve the reliability of 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.
