Description
本発明は空調冷凍機器に使用される全密閉型冷凍圧縮機用の電動機および電動機のリード線およびリード線編組部繊維に関する。 The present invention relates to a motor for a hermetic refrigeration compressor used in an air-conditioning refrigeration apparatus, a lead wire of the motor, and a lead wire braided portion fiber.
近年、空調，冷凍機器に使用されている電動機は、繊維を編み上げてなる編組部を有する絶縁被覆構成のリード線を使用したものであり、実開平４−１２８０６３で述べられているような漏れ電流の発生を防ぐ目的や、冷媒Ｒ１３４ａを使用した冷凍サイクルの１部が閉塞するという問題を対策する目的などから、編組部に使用する繊維に静電気防止，滑り性向上などを目的に塗布している油剤を除去するためのリード線洗浄を行ったものが採用されてきている。
以下に従来の電動機のリード線の課題について説明する。 The problem of the lead wire of the conventional electric motor will be described below.
図２は従来の電動機のリード線の構造を示すものである。図２において、１４は糸を編み上げた編組部、１２はフィルム部である。 FIG. 2 shows a structure of a lead wire of a conventional electric motor. In FIG. 2, reference numeral 14 denotes a braided portion where yarn is knitted, and 12 denotes a film portion.
冷媒Ｒ１２用のコンプレッサーに使用されてきた電動機のリード線編組部には、糸を編み上げる際の糸切れなどの作業性の問題を解決するため、油剤が塗布されている。冷媒Ｒ１２を使用した冷凍サイクル内において、この油剤および編組部に含まれる油脂類における閉塞現象はみられていない。 An oil agent is applied to the lead wire braided portion of the electric motor that has been used in the compressor for the refrigerant R12 in order to solve workability problems such as yarn breakage when the yarn is knitted. In the refrigeration cycle using the refrigerant R12, the oil agent and the fats and oils contained in the braided portion are not clogged.
しかしながら、冷媒Ｒ１３４ａを使用した冷凍サイクル内において、この油剤を塗布したリード線を用いると、冷凍サイクルの一部が閉塞することが確認されている。 However, it has been confirmed that when a lead wire coated with this oil agent is used in a refrigeration cycle using the refrigerant R134a, a part of the refrigeration cycle is blocked.
したがって、冷媒Ｒ１３４ａに使用される電動機のリード線については、編組部に使用する繊維に静電気防止，滑り性向上などを目的に塗布している油剤を除去するためのリード線洗浄を行っている。 Therefore, the lead wire of the motor used for the refrigerant R134a is subjected to lead wire cleaning for removing the oil applied to the fibers used in the braided portion for the purpose of preventing static electricity and improving slipperiness.
しかしながら上記従来の構成では、編組部の糸を編み上げる際糸切れなどの作業性の問題が生じるため油剤を使用しなければならず、また従来の油剤を使用すると漏れ電流の発生や冷媒Ｒ１３４ａを用いた冷凍サイクル内において冷凍サイクルの一部を閉塞する原因となることから、リード線洗浄を行わなくてはならないという問題を有していた。 However, in the above-described conventional configuration, an oil agent must be used because a problem of workability such as yarn breakage occurs when knitting the yarn of the braided portion, and when a conventional oil agent is used, generation of leakage current and use of the refrigerant R134a are required. since the cause for closing the part of the refrigeration cycle in the stomach refrigeration cycle, there is a problem that must be performed leads wash.
本発明は上記従来の問題点を解決するもので、漏れ電流発生防止や冷媒Ｒ１３４ａを使用する冷凍サイクルの閉塞現象の原因とされる物質を使用しない電動機のリード線を提供することを目的としている。 SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a lead wire for an electric motor that does not use a substance that causes leakage current generation and causes a clogging phenomenon in a refrigeration cycle that uses a refrigerant R134a. .
上記課題を解決するために、本件出願に係る発明のリード線編組部の製造方法は、繊維に静電気防止，滑り性向上などを目的に塗布されている油剤を一旦洗浄した後に、前記繊維から糸を製造し、前記糸に鉱油、ハードアルキルベンゼン、エステル油の冷凍機油のみを塗布した後に、さらに前記糸を編み上げて編組部を製造するリード線編組部の製造方法である。 In order to solve the above problems, a manufacturing method of the lead wire braid portion of the engaging Ru invention present application, anti-static the fibers, after once washed oil agent has been applied and the purpose lubrication improving, from the fibers This is a method for manufacturing a lead wire braided part in which a yarn is manufactured, and only the mineral oil, hard alkylbenzene, ester oil refrigerating machine oil is applied to the yarn, and then the yarn is further knitted to produce a braided part .
本件出願に係る発明によれば、編組部に使用する繊維に静電気防止，滑り性向上などを目的に塗布している油剤を一旦洗浄し、その後鉱油，ハードアルキルベンゼン，エステル油の冷凍機油を塗布した後、リード線被覆に編み上げることにより、糸を編み上げる際の糸切れやケバなどの作業性の問題についても改善することができる。 According to the invention of the present application, the oil used for the purpose of preventing static electricity and improving slipperiness is once washed on the fibers used for the braided portion, and then the mineral oil, hard alkylbenzene, ester oil refrigerating machine oil is applied. Later , by knitting the lead wire , it is possible to improve workability problems such as yarn breakage and knurls when the yarn is knitted.
また、鉱油，ハードアルキルベンゼン，エステル油の冷凍機油を使用することにより冷媒Ｒ１３４ａの冷凍サイクルの閉塞現象を防止することができる電動機を実現できるものである。 Further, by using a refrigerating machine oil of mineral oil, hard alkylbenzene, or ester oil, an electric motor that can prevent the clogging phenomenon of the refrigerating cycle of the refrigerant R134a can be realized.
以下本発明の実施の形態について、図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the drawings.
（実施の形態１）
図１において、１１は電動機のリード線の編組部、１２はフィルム部、１３は電線部である。編組部に使用する繊維に静電気防止，滑り性向上などを目的に塗布している油剤を一旦洗浄し、その後鉱油，ハードアルキルベンゼン，エステル油の冷凍機油を塗布した後、あるいは編組部に使用する糸を、油剤を塗布せずに製造した後、鉱油，ハードアルキルベンゼン，エステル油の冷凍機油を塗布した後リード線被覆に編み上げることにより、糸を編み上げる際の糸切れやケバなどの作業性の問題について改善することができる。
(Embodiment 1)
In FIG. 1, 11 is a braid part of the lead wire of an electric motor, 12 is a film part, 13 is an electric wire part. Yarn antistatic to fibers used in the braid, once washed oil agent is coated and the intended lubrication improving, then mineral oil, after a hard alkylbenzene, the refrigerating machine oil of the ester oil is applied, or used to braid and was prepared without applying an oil solution, mineral oil, hard alkylbenzene, by braiding the lead wire coated after coating the refrigerating machine oil of the ester oil, the workability problems such as yarn breakage and fluff during braiding yarn Can be improved.
また、鉱油，ハードアルキルベンゼン，エステル油の冷凍機油を使用することにより冷媒Ｒ１３４ａの冷凍サイクルの閉塞現象を防止することができる。 Moreover, the blockage phenomenon of the refrigerating cycle of refrigerant | coolant R134a can be prevented by using the refrigerating machine oil of mineral oil, hard alkylbenzene, and ester oil.
本発明のリード線編組部の製造方法は、編組部に使用する繊維に静電気防止，滑り性向上などを目的に塗布している油剤を一旦洗浄することが不要となり、編組部の糸を編み上げる際の糸切れやケバなどの作業性の問題についても改善することができる。また冷媒Ｒ１３４ａを使用した冷凍サイクルの閉塞現象を防止することができる。 The manufacturing method of the lead wire braided part of the present invention eliminates the need to once wash the oil applied to the fibers used in the braided part for the purpose of preventing static electricity and improving the slipperiness.
