Description of the invention (/) The present invention relates to a connection member for connecting a drive unit casing to a compressor unit casing. This type of connector is used in the compressor assembly to connect most of the compressor housing of the compressor unit to the housing containing the drive unit, such as the housing of the motor. For structural reasons, these housings cannot be manufactured in one piece. The coupling between the shaft of the rotor of the compressor unit and the output shaft of the drive unit is located in the connection. The ii-wheel transmission or other coupling variable can be integrated in this connection. The compressor assembly produces a lot of chirp. In order to limit the noise level, a vibration damper is used to insulate the assembly from the ground, and the frame is provided with a sound-restricting material. The ventilation ducts are also sound-treated. Although these methods have achieved considerable noise mitigation effects, the number of rattling stages of the compressor assembly is still extremely high. In the course of efforts to further reduce this series of noises, the research results show that a large amount of noise energy is generated in the compressor unit, which is converted into unwanted vibration and noise under the structural characteristics of the rectification assembly. In particular, the resonance frequency of this assembly structure is excited by the pulse frequency of the compressor, which results in the emission of excess noise energy. Printed by the Central Ministry of Economic Affairs and printed only by consumer cooperatives (please read the precautions on the back before filling out this page). Notice, especially the connection between the compressor unit and the housing of the drive unit must be a noise, vibration and noise The support point is passed to the motor and this connection point. The present invention aims to provide a connecting member in which chirp radiation and vibration transmission are minimized, and noise output of a compressor assembly is reduced. This object is achieved according to the present invention, in which the connector is applied to the Chinese paper standard (CNS) A4 (210X 297) in the wall of the paper at least to the paper size. Fifth, the description of the invention () A part is provided with ribs so that the height of each rib is at least equal to 1.5 times the thickness of the wall portion for which this rib 11 is erected, and it reaches a height of--half the thickness The ribs are equal to at least half of the thickness described above.

Description of the invention (4) In the first figure, a compressor It includes a compressor unit 1 that is, for example, a worm compressor unit with a rotor or a spiral 1 calendaring unit with two rotors; a drive unit 2 formed by an electric motor; and a connecting member 3. Connect the housing 4 of the drive unit 2 to the housing 5 of the compressor unit 1, and the coupling 6 is located between the output shaft 7 of the drive unit 2 and the rotor shaft 8 of the compressor unit 1. In the case where the compressor unit 1 is a screw compressor including two rotors, the rotor shaft can be driven by a gear transmission device, a belt transmission device, or other coupling variable. The connecting member 3 includes a tubular portion 9 with a flange 10 at one end for fixing to the casing 5 of the compressor unit 1 and a flange 11 at the larger end for fixing to the casing 4 of the driving unit 2 on. The sound energy produced by the compression process of the compression unit is very rich in tonal characteristics and pseudo-consisting of a decisive signal. The minimum decisive signal, 卽 tone, 傜 a buckle tone, has a frequency equal to the frequency at which the compressor unit draws in air from the surroundings and discharges it to the compressor unit outlet. The air is compressed in the sagittal chamber and is quickly discharged into the outlet, so that the process does not proceed in a gradual manner. The result is a harmonic sound of this tone. These harmonics have a frequency that is an integer multiple of the fundamental frequency. Depending on most processes and geometric parameters, it produces more or less harmonics. The amplitude is important or not important relative to the tone. This total tone energy expands the casing 5 and the flanged structure of the compressor unit, and converts this energy into vibration and noise in their respective ways. In order to limit this kind of vibration, the rib portion 12 is provided on one of the wall portions of the tubular portion 9.

Part of the invention description (4) and preferably more than half, one configuration method is to pseudo divide the outer side between the flanges 10 and .11 into wall sections 13. In the example k, these ribs 12 are provided on the outside of the above-mentioned wall portion of the tubular portion 9, but may also be located on the inside. These ribs meet special requirements. As detailed in the sixth picture, the height 肋 or the rib 1.2 is at least 1.5 times and, for example, 2 times the thickness D of the wall portion for which it is erected, and from this rib 12 to half the height to the height The width B is at least half of the above thickness, and is equal to this thickness, for example. Since the connection member is like a metal casting, the rib portion 12 may be enlarged toward the base part more or less based on the reason of the inlay technique. The top of the rib portion 12 is rounded, and the rib portion 12 is connected to the wall portion with a modified portion, and the rib portion 12 stands upright on this wall portion. The above-mentioned pattern formed by the ribs 12 also meets special requirements: that is, the first special emblem type having a dense structure that bends each wall section 13 thereof has a resonance frequency, and the compressor unit 1 reaches and includes the highest frequency The excitation frequency cannot excite the wall section 13. The highest harmonic frequency, that is, the excitation component of the highest frequency, no longer produces any so-called ventilated pattern or first curved pattern of wall sections. As a result, this wall section 13 壁 cannot radiate any noticeable chirp. Each wall section 13 will start to vibrate under dynamic excitation. When the generated vibration has a frequency having one of the resonances of this wall section 13, it will radiate far more chirps than the wall section for each frequency.

The first characteristic type is also called "ventilation type J. The above type depends on the characteristics of the compressor unit such as the speed and rotor structure. These emblems will affect the excitation frequency of the compressor. Most wall sections 13 A groove 14 may be provided for internal cooling of the connecting member 3. In the representative example, the ribs 12 and the wall sections 13 are located on the flanks of the tubular portion 9. One of the planing wings includes portions that are angled to each other. Tubular The upper and lower sides of the portion 9 have flat portions. As shown in FIG. 1, the connecting member 3 is placed on a support 16 with a lower portion of this flat portion, and an elastic pad 15 is placed therebetween. The driving unit The outer shell 4 of 2 is placed on a second fulcrum 17 in the same way. ≫ Obviously, the ribs 2 and the wall segments 13 may also be located on the upper and / or bottom sides of the tubular portion 9 only. The flange 11 is substantially opposite to The opening at the corresponding end of the tubular portion 9 extends outward. This flange 11 is shown with four openings 18 and is provided with threads inside, and the shell 4 is fixed by bolts. Conversely, the convex wire 10 does not open at the end of the tubular portion 9 Symmetric, in other words, the flange 10 protrudes outward on one side and towards the other This flange 10 is provided with an opening 19 for it to be fixed to the housing 5 by bolts. Therefore, the above-mentioned connection member 3 greatly reduces noise radiation. The connection member 3 does not need to be located in the extension of the compressor unit 1 and the drive unit 2. It For example, the compressor unit and the drive unit can be adjacent to it. The paper size applies to the Chinese National Standard (CNS) A4 (2l0X; 297mm) at this paper size.
