Description
Technical field
The present invention relates to a kind of adjustable elastic support structure, specifically be used for rotary machinery (screw compressor, motor etc.) and connect, belong to the bracing or strutting arrangement technical field with the support of support.
Background technology
Before the present invention makes, in prior art, be used for rotary machinery (screw compressor, motor etc.) and connect, normally adopt elastomer vibration absorber or elastomer beam structure with the support of support.This kind structure can not be eliminated screw compressor or motor and support because of the error of processing and assembling causes, makes the unbalance stress of each strong point, and produces additional force for screw compressor or motor and connecting cylinder, makes the vibrations of unit and noise become greatly.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby providing a kind of exists under the situation of mismachining tolerance or distortion at screw compressor or electric machine stand, can make each strong point can both obtain proper supporting, connection places such as connecting cylinder do not produce additional force, guarantee the adjustable elastic support structure of machine even running.
Main solution of the present invention is achieved in that
The present invention mainly adopts vibration absorber to link with base plate and support respectively, and motor and support link, and props up the chassis, top by a screw, and screw is propped up in nut check, and attachment bolt connects base plate and chassis.
One gap delta is arranged between described base plate and the chassis; Numerical value by a screw scalable δ.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; The transmission of motor oscillating can be eliminated and reduce to resiliency supported; Adjustable supports can be eliminated the foozle and the alignment error of each parts, makes each strong point obtain desirable support force, reduces extraneous vibration and noise; Can reduce the additional stressed of extra bending moment and attachment bolt on the connecting cylinder, guarantee the machine even running.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the stressed schematic diagram of the single fulcrum adjustable supports of the present invention.
Fig. 3 is the stressed schematic diagram of the present invention's three fulcrum adjustable supports.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly is made up of chassis 1, base plate 2, attachment bolt 3, nut (being used for locking) 4, a screw 5, motor 6, attachment bolt nut 7,9, support 8, vibration absorber 10, bolt 11 (mounting shock absorber) etc.
Vibration absorber 10 of the present invention links with base plate 2 and support 8 respectively by bolt 11 and bolt and nut 9, and motor 6 links by bolt and nut 7 and support 8.By chassis 1,5 tops of a screw, make vibration absorber 10 distortion produce support force, control vibration absorber 10 deflections are controlled the support force of fulcrum.Nut 4 is used for a locking screw 5, and connects base plate 2 and chassis 1 with attachment bolt 3.Like this, be flexible coupling for adjustable between motor 6 and the chassis 1.Substantially eliminated the influence of various sum of errors distortion, and made the stressed minimum of connecting cylinder support force.
Embodiment one: with single fulcrum adjustable supports is example.
As shown in Figure 1: gear box side is that beam supports, and can think to be rigidity that then all deviations support balance by motor.Motor weight is G, and then motor has vertically downward an active force G to frame, and under theoretical situation, frame has vertically upward a support reaction N, is used for the weight of balance motor.At this moment can think attachment bolt on the connecting cylinder because of various sum of errors distortion produce additional stressed be 0.
When the influence of considering various errors, support is than original low δ, thus the center line and the stripped deviation one α angle that cause motor, and at this moment, attachment bolt will be subjected to the additional force T that produces because of error on the connecting cylinder.Make base plate 2 rising δs by adjusting the screw 5 among Fig. 1 this moment, and whole so stressed again with identical in theory, promptly the suffered additional force T of the attachment bolt on the connecting cylinder will disappear.
Embodiment two: for a kind of typical helical-lobe compressor connects installation diagram.
As shown in Figure 3: compressor is to hang on the uni-drive gear box, and motor is connected with uni-drive gear box by connecting cylinder and shaft coupling.They are sitting on the base as a rigid unitary, and the centre is provided with beam and vibration absorber (adjustable elastic support).
The manufacturing of each parts and the composition error of installation are bigger, they comprise: the error of perpendicularity of height of center error, motor and gear box conjunction plane etc., composition error can reach more than the 10mm, the many fulcrums of whole unit support (example 8 points), cause the stressed serious inequality (falling far short) of each strong point with ideal is stressed, make connecting cylinder be subjected to very big extra bending moment simultaneously, make unit produce vibration and noise.Can make the motor body deformation of welding pattern when serious, influence the motor operate as normal.
All there is certain rigidity in various vibration absorbers, and it is stressed to be linear relationship with being out of shape basically, and specified meeting of routine Z5 type vibration absorber is that 1000kg, specified deflection are 10mm, and its rigidity is 100kg/mm.
According to the weight and the center of gravity of each main parts size, not being subjected to extra bending moment with connecting cylinder is prerequisite, calculates the desirable support force of each strong point.
By the position of a screw 5 change base plates 2, control the support force of the deflection of each vibration absorber with regard to this strong point of may command.The support force of supposing certain strong point is required to be 700kg, then makes vibration absorber distortion 7mm by a screw.Like this its make alignment error all " dissolving " among the gap on base plate and chassis " δ ".
