Abstract

PURPOSE:To contemplate stabilization of oil supply by inserting a twist plate into an oil supply piece secured to an end of a drive shaft and setting the distance between the end of the twist plate and the oil supply piece to not more than a half of the inner diameter of the oil supply piece, thus pumping up lubricating oil by a centrifugal pumping action. CONSTITUTION:The end portion of a twist plate 2' is inserted in an oil supply piece 3' secured to an end of a drive shaft 1'. Even when an oil level 4 is lowered under the drive shaft 1', lubricating oil may be pumped up by a centrifugal pumping action and supplied to machine parts. Furthermore, by setting the distance A between the end of the twist plate 2' and the oil supply piece 3' to not more than a half of the inner diameter d of the oil supply piece 3', oil feed conditions may be rendered more satisfactory, thereby improving reliability. With this arrangement, oil feed to machine parts especially upon lowering of an oil level may be stably carried out, and wear, scuffing or the like occurring on machine parts may be prevented.

Description

【発明の詳細な説明】 〔発明の利用分野〕 本発明は、密閉形圧縮機の給油機構に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an oil supply mechanism for a hermetic compressor.

〔従来技術〕[Prior art]

て行なっている。Generally, a hermetic compressor has five mechanical parts, an oil reservoir under the electric part, and the amount of oil is adjusted and sealed so that the oil level reaches the mechanical part. Lubricating the mechanical parts is accomplished by attaching a lubrication piece to the tip of the drive shaft and locking a pump such as a twist plate to the inside diameter of the drive shaft.

油が不充分となり機械部分の摩耗。However, in a single oil supply structure, if the oil level drops below the tip of the drive shaft, such as when starting the compressor, the oil supply will be insufficient and the mechanical parts will wear out.

咬りが発生することがあった。Occasionally bites occurred.

〔発明の目的〕[Purpose of the invention]

本発明は以上のような問題点を解決するための一方法を
提供するものである。The present invention provides a method for solving the above problems.

〔発明の概要〕[Summary of the invention]

駆動軸、駆動軸先端に係止した給油ピース、給油ピース
内に達し、駆動、軸内径に係止されたひねり板により構
成される密閉形圧縮機の給油機構。A lubrication mechanism for a hermetic compressor that consists of a drive shaft, a lubrication piece that is fixed to the tip of the drive shaft, and a twist plate that reaches inside the lubrication piece and is latched to the inner diameter of the drive and shaft.

〔発明の実施例〕[Embodiments of the invention]

以下１図面に従い説明する。 This will be explained below with reference to one drawing.

第１図は、従来の給油機構を示す図で、駆動軸１内径に

。FIG. 1 is a diagram showing a conventional oil supply mechanism, in which a twisting plate 2 attached to the inner diameter of the drive shaft 1 is fixed to the tip of the drive shaft 1.

給油ピース３とによって給油機構を成している。The oil supply piece 3 constitutes an oil supply mechanism.

る。If the oil level 4 suddenly drops below the tip of the drive shaft 1, such as when starting up the compressor, the oil supply piece 3 alone will not be enough to supply oil 4 to the machine part (not shown), and the machine part 1 will be It is obvious that wear and chewing become more likely to occur. Figure 2 shows an embodiment of the present invention in which the tip of the twist plate 2' is inserted into the oil supply piece 3' so that even if the oil level 4 drops below the tip of the drive shaft 1', the action of the centrifugal pump It is designed to pump up lubricating oil and supply it to mechanical parts.

また、ひねり板２′先端と給油ピース３′の距離Ａを給

油条件が良好となり信頼性が向上する。Furthermore, if the distance A between the tip of the twist plate 2' and the oil supply piece 3' is set to 1/2 or less of the inner diameter d of the oil supply piece 3', the oil supply conditions will be even better and reliability will be improved.

〔発明の効果〕〔Effect of the invention〕
