Embodiment 1

[0015] Embodiment 1: Take the single fulcrum adjustable support as an example.

[0016] like figure 1 Shown: The gearbox side is supported by a shock absorber, which can be considered rigid, and all deviations are balanced by the motor support. The weight of the motor is G, and the motor has a vertical downward force G on the frame. In theory, the frame has a vertical upward support force N, which is used to balance the weight of the motor. At this time, it can be considered that the additional force of the connecting bolts on the connecting cylinder due to various errors and deformations is zero.

[0017] When considering the influence of various errors, the bracket is lower than the original δ, which causes the center line of the motor to deviate from the theory by an angle of α. At this time, the connecting bolts on the connecting cylinder will be subjected to an additional force T due to the error. At this time by adjusting figure 1 The top screw 5 in the middle makes t...

Embodiment 2

[0018] Embodiment 2: It is a connection and installation diagram of a typical screw compressor.

[0019] like image 3 As shown: the compressor is hung on the transmission gearbox, and the motor is connected with the transmission gearbox through the connecting cylinder and coupling. They sit on the base as a rigid whole, with shock-absorbing pads and shock absorbers (adjustable elastic supports) in the middle.

[0020] The comprehensive errors of the manufacture and installation of each component are relatively large, including: the center height error, the verticality error of the connecting surface of the motor and the gearbox, etc. The comprehensive error can reach more than 10mm, and the whole unit is supported by multiple fulcrums (for example, 8 points), resulting in The force of each support point is seriously uneven (far from the ideal force), and at the same time, the connecting cylinder is subjected to a large additional bending moment, which causes vibration and no...

Abstract

The invention relates to an adjustable elastic support structure, specifically for the support connection between rotary machines (screw compressors, motors, etc.) and machine bases, and belongs to the technical field of support devices. It mainly adopts the shock absorber to be connected with the bottom plate and the bracket respectively, the motor is connected with the bracket, the chassis is supported by the top screw, the nut locks the top screw, and the bottom plate and the chassis are connected by the connecting bolt. The invention has a simple, compact and reasonable structure; the elastic support can eliminate and reduce the transmission of motor vibration; the adjustable support can eliminate the manufacturing error and installation error of each component, so that each support point can obtain ideal support force and reduce additional vibration and noise ; It can reduce the additional bending moment on the connecting cylinder and the additional force of the connecting bolts, so as to ensure the smooth operation of the machine.

Description

technical field [0001] The invention relates to an adjustable elastic support structure, specifically for the support connection between rotary machines (screw compressors, motors, etc.) and machine bases, and belongs to the technical field of support devices. Background technique [0002] Before the present invention was made, in the prior art, it was used for the supporting connection of the rotary machine (screw compressor, motor, etc.) and the machine base, usually adopting an elastomer shock absorber or an elastomer shock absorber structure. This structure cannot eliminate the error caused by processing and assembly of the screw compressor or the motor and the machine base, so that the stress on each support point is uneven, and it will generate additional force to the screw compressor or the motor and the connecting cylinder, making the unit's Vibration and noise become louder. Contents of the invention [0003] The purpose of the present invention is to overcome th...
