Abstract
The present invention designs a kind of hydraulic fitting vibration testing device, it include more cam disks, mounting flange, special hydraulic motor, base support, spring structure bracket, deep groove ball bearing, by test specimen.The geometry of more cam disks is the synthesis of sine curve and circle, is acted on deep groove ball bearing, is realized by the vibration of test specimen with the shape of its class cam with the rotation of required revolving speed by the mounting flange being connected with hydraulic motor.The present invention is directed to hydraulic fitting vibration test, suitable for the vibration requirement of low-speed stable, has the characteristics that compact-sized, noise is small, practical.
Description
Technical field
The present invention relates to hydraulic fitting test methods, more particularly to a kind of hydraulic fitting vibration testing device.
Background technique
According to the requirement of vibration test in national standard GB/T 26143-2010 " hydraulic fitting test method ", energy is needed
Rotation or axial plane internal vibration are provided, vibration frequency is the device of 10~50 Hz.The method that existing vibration generates has machinery
Formula, electrodynamic type and electric-liquid type.Since this test is for the of less demanding of vibration frequency, it is unsuitable for the electrodynamic type of higher operating costs
Or electric-liquid type.Existing mechanical shaker have straightly-drive type with it is centrifugal, wherein straightly-drive type includes crank link mechanism, song
Handle slide block mechanism and cam ejection pin mechanism；It is centrifugal, need a pair of engaged gears.But both modes have been required to biggish
Running space, and the generation of its movement is directly driven by a motor, the requirement to motor is very high.
Summary of the invention
The purpose of the invention patent, suitable for the vibration requirement of low-speed stable, is mentioned for hydraulic fitting vibration test
For a kind of hydraulic fitting vibration testing device, have the characteristics that compact-sized, noise is small, practical.
In order to achieve the above objectives, the present invention adopts the following technical solutions:
A kind of hydraulic fitting vibration testing device, including more cam disks, mounting flange, special hydraulic motor, pedestal
Bracket, spring structure bracket, deep groove ball bearing, by test specimen.It is characterized by: more cam disks are solid by standard component bolt
It is scheduled on mounting flange, mounting flange is bolted on hydraulic motor by standard component, and the special hydraulic motor passes through mark
Quasi- part bolt is fixed on base support, and the spring structure bracket is fixed on base support by standard component bolt, described
Deep groove ball bearing is fixed on by interference fit by test specimen steel pipe, and more cam disks keep inconsistent with deep groove ball bearing.
The geometry of more cam disks is the synthesis of sine curve and circle, passes through the fixation being connected with hydraulic motor
Orchid is acted on deep groove ball bearing with the rotation of required revolving speed with the shape of its class cam, is realized by the vibration of test specimen.
Compared with prior art, the present invention will be apparent below prominent substantive features and significant:
The present invention is adjusted by revolving speed of the variable-frequency motor to hydraulic pump, and then changes vibration frequency, and having can manipulate
The strong feature of property；Since hydraulic fitting vibration test is fatigue durability test, being equivalent to will to all test parts
Fatigue test is done, it is compact-sized that the used hydraulic motor of the present invention drives the mechanism of more cam disks to have, and inoperative component is few
Feature can satisfy the requirement of fatigue test；In addition its running space is small, and impact is small, has the characteristics that run smoothly, more cams
Disk acts directly on deep groove ball bearing, overcomes the big defect of vibration noise.
