産業上の利用分野
本発明は、圧縮機における防振装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vibration isolating device for a compressor.
従来例の構成とその問題点
一般に空調機器、冷凍機等の圧縮機取付け構造
において、省スペース化として、下部の支持を圧
縮機の底面投影面積内に設定している。このこと
からかかる構造は前記圧縮機が傾き、上記支持を
必要とする構成であつた。Conventional Structure and Problems Generally, in a compressor mounting structure for air conditioners, refrigerators, etc., the lower support is set within the bottom projected area of the compressor to save space. For this reason, in such a structure, the compressor is tilted and requires the above-mentioned support.
その防振対策として従来、第１図、第２図に示
されるような圧縮機の防振構造が採用されてい
た。 Conventionally, as a vibration-proofing measure, a compressor vibration-proofing structure as shown in FIGS. 1 and 2 has been adopted.

が溶接等で取り付けられており、前記脚部２と基

を設けた下部防振構造、前記圧縮機１の上面の中

貫通穴を設けた支持基板６を配設し、前記支持基
板６の貫通穴に、前記突出ピン５が貫通するゴム
等の弾性体からなる防振具７を設けた、上部防振
構造からなつている。 The configuration shown in FIG.
is attached by welding or the like, and a vibration isolator 4 made of an elastic material such as rubber is installed between the leg portion 2 and the base plate 3.
A lower vibration isolation structure is provided, a protruding pin 5 protruding upward is provided on the central axis of the upper surface of the compressor 1, and a through hole through which the protruding pin 5 passes is provided above the compressor 1. It has an upper vibration isolating structure in which a support substrate 6 is disposed, and a vibration isolator 7 made of an elastic material such as rubber is provided in a through hole of the support substrate 6 through which the protruding pin 5 passes.
ところが、この構造は圧縮機１の上面に設けら

ミナル部を保護するカバー８と干渉しないよう

い。このために、かかる構造は圧縮機１の上方に
広いスペースが必要となる欠点を有していた。 However, in this structure, the vibration isolator 7 that penetrates the protruding pin 5 provided on the top surface of the compressor 1 must be positioned above the cover 8 so that it does not interfere with the cover 8 that protects the terminal section. . For this reason, such a structure has the disadvantage that a large space is required above the compressor 1.
第２図は、圧縮機１１の上面の中心軸から離れ

前記圧縮機１１の上方に、前記突出ピン１２が貫

することがないため、圧縮機１１の上方のスペー
スが小さくて済む。ところが、この構造は、圧縮
機１１の中心軸から離れた位置で、突出ピン１２
が防振具１４を貫通する構造となつているため

には、防振具１４は大きな圧縮力を受け、圧縮方
向に比較的剛性の大きいゴム等の弾性体では、振
動を充分に吸収することができないという欠点を
有していた。 In FIG. 2, a protruding pin 12 that protrudes upward is provided on the upper surface of the compressor 11 at a position away from the central axis.
A support substrate 13 having a through hole through which the protrusion pin 12 passes is disposed above the compressor 11, and an elastic material such as rubber, through which the protrusion pin 12 passes, is provided in the through hole of the support substrate 13. It has an upper vibration isolating structure in which a vibration isolator 14 is provided. With this structure, the vibration isolator 14 does not interfere with the terminal cover 15, so the space above the compressor 11 can be small. However, in this structure, the protruding pin 12 is located away from the central axis of the compressor 11.
Since the vibration isolator 14 is structured to penetrate through the vibration isolator 14, the vibration isolator 14 is subjected to a large compression force in the case of a rotary compressor or the like that has large vibrations in the circumferential direction, and is relatively rigid in the compression direction. Large elastic bodies such as rubber have the disadvantage of not being able to absorb vibrations sufficiently.

Reference numeral 23 denotes a fitting hole provided in the leg portion 22, and is provided within the bottom projected area of the compressor 21.
Reference numeral 24 denotes a substrate on which the compressor 21 is mounted, and a support pin 25 is fixed at a proper position on the substrate coaxially with the center of the fitting hole 23 by welding or the like. Reference numeral 26 denotes a lower vibration isolating rubber interposed between the leg portions 22 and the substrate 24, and is made of an elastic material such as natural rubber. Reference numeral 27 denotes a protruding pin provided by welding or the like at a position away from the center of the terminal cover 31 and the upper surface of the upper surface of the compressor 21, and passes through the through hole 29 of the support substrate 28 located above.
