Abstract
A kind of hydraulic fitting vibration testing device of present invention design, it include many cam disks, mounting flange, special hydraulic motor, base support, spring structure support, deep groove ball bearing, by test specimen.The geometry of many cam disks is the synthesis of sine curve and circle, by the mounting flange being connected with hydraulic motor, is rotated, is acted on the shape of its class cam on deep groove ball bearing with required rotating speed, realized by the vibration of test specimen.The present invention is directed to hydraulic fitting vibration test, it is adaptable to the vibration requirement of low-speed stable, with compact conformation, noise it is small, it is practical the characteristics of.
Description
Technical field
The present invention relates to hydraulic fitting test method, more particularly to a kind of hydraulic fitting vibration testing device.
Background technology
According to national standard GB/T 26143-2010《Hydraulic fitting test method》The requirement of middle vibration test, it is desirable to have energy
Rotation or axial plane internal vibration are provided, vibration frequency is 10~50 Hz device.The method that existing vibration is produced has machinery
Formula, electrodynamic type and electric-liquid type.Because this experiment is for the less demanding of vibration frequency, the higher electrodynamic type of use cost is unsuitable for
Or electric-liquid type.Existing mechanical shaker have straightly-drive type with it is centrifugal, wherein straightly-drive type include toggle, song
Handle slide block mechanism and cam ejection pin mechanism；It is centrifugal, need a pair of engaged gears.But both modes are required to larger
Running space, and its motion generation be directly driven by a motor, the requirement to motor is very high.
The content of the invention
The purpose of patent of the present invention is to be directed to hydraulic fitting vibration test, it is adaptable to the vibration requirement of low-speed stable, is carried
For a kind of hydraulic fitting vibration testing device, with compact conformation, noise it is small, it is practical the characteristics of.
To reach above-mentioned purpose, the present invention uses following technical proposals：
A kind of hydraulic fitting vibration testing device, including many cam disks, mounting flange, special hydraulic motor, base support,
Spring structure support, deep groove ball bearing, by test specimen.It is characterized in that：Many cam disks are bolted to by standard component
On mounting flange, mounting flange is bolted on hydraulic motor by standard component, and the special hydraulic motor passes through standard component
It is bolted on base support, the spring structure support is bolted on base support by standard component, the zanjon
Ball bearing is fixed on by test specimen steel pipe by interference fit, and many cam disks keep inconsistent with deep groove ball bearing.
The geometry of many cam disks is the synthesis of sine curve and circle, passes through the fixation being connected with hydraulic motor
Orchid, is rotated with required rotating speed, is acted on the shape of its class cam on deep groove ball bearing, is realized by the vibration of test specimen.
The present invention compared with prior art, will be apparent below protruding substantial feature and significant advantage：
The rotating speed of hydraulic pump is adjusted by variable-frequency motor by the present invention, and then changes vibration frequency, strong with navigability
The characteristics of；Because hydraulic fitting vibration test is fatigue durability experiment, it will do tired equivalent to all test parts
Labor is tested, and the present invention use the mechanism of many cam disks of hydraulic motor drive to have a compact conformation, the characteristics of inoperative component lacks,
It disclosure satisfy that the requirement of fatigue test；Its other running space is small, impacts small, the characteristics of with operating steadily, many cam disks
Act directly on deep groove ball bearing, overcome the big defect of vibration noise.
