Abstract
The invention relates to the field of fastener testing, in particular to a vibration test device of a self-locking nut for bearing fastening. The vibration test device comprises an installation seat and a test bolt. The installation seat comprises a base part used for being fixedly connected with a vibrator and an installation part used for installing the test bolt and a corresponding tested nut. An installation hole used for installation of the test bolt and radial movement of the test bolt is formed in the installation part. A tested nut installation section is arranged on the test bolt, and a limit shoulder used for being matched with the tested nut in a blocking mode is arranged at the adjacent position of the tested nut and other parts of the test bolt. The vibration test device of the self-locking nut for bearing fastening can greatly reduce the weight needed to bear by the vibrator, can complete vibration tests of the self-locking nut on the normal vibration tester, and reduces production cost of the self-locking nut for bearing fastening.
Description
Technical field
The present invention relates to securing member field tests, particularly relate to the fastening self-locking nut vibration testing device of a kind of bearing.
Background technology
Aero-Space engine is due to the requirement of stability and reliability, its bearing requirements must be reliable fixing, the fastening self-locking nut of bearing is then the parts for solid bearing in Aero-Space engine, it is a kind of securing member of specification super large, the self-locking property that it is had by self-locking nut itself, realize the compression to rev-happy engine bearing, have the advantages that simple, the anti-loose ability of structure is strong, efficiency of assembling is high.
In conventional vibration test, all self-locking nut is arranged on use equipment, then on vibration test machine, vibration test is carried out, but because bearing fastening self-locking nut specification is larger, the weight of itself is extremely heavy, add corresponding test use equipment, common vibration rig, due to the restriction of range, cannot carry out vibration test to it at all.And to buy wide range vibration rig specially be obviously to cause significantly increasing of the cost of manufacturer.If by means of only the vibration test of common vibration test machine with regard to the fastening self-locking nut of the complete matched bearings of energy, the manufacturing cost of the fastening self-locking nut of bearing obviously can be reduced widely.
Summary of the invention
The object of the present invention is to provide a kind of can on common vibration test machine the fastening self-locking nut vibration testing device of bearing of the vibration test of the fastening self-locking nut of complete matched bearings, to reduce the production cost of the fastening self-locking nut of bearing.
In order to solve the problem, bearing of the present invention fastening self-locking nut vibration testing device is by the following technical solutions: the fastening self-locking nut vibration testing device of bearing, comprise mount pad and test bolt, described mount pad comprise for the base portion that bobbing machine is fixedly connected with and the mounting portion for installing described test bolt and corresponding tested nut, described mounting portion is provided with for installation test bolt, and the mounting hole that availability test bolt is radially movable, test bolt is provided with tested nut construction section, tested nut construction section is provided with the spacing shoulder for coordinating with tested nut block with the adjacent of the other parts of test bolt.
Described test bolt is hollow bolt.
Also comprise the test pad for being fitted between tested nut and described spacing shoulder.
The mounting portion of described mount pad is tabular, and the base portion of mount pad is strip and is provided with the bolt hole for being connected with bobbing machine worktable.
Described mounting hole is the elongated hole on above-below direction.
Because the mounting portion of the mount pad of the fastening self-locking nut vibration testing device of bearing of the present invention is provided with for installation test bolt, and the mounting hole that availability test bolt is radially movable, and the tested nut construction section testing bolt is provided with the spacing shoulder for coordinating with tested nut block with the adjacent of the other parts of test bolt, therefore, when in use, the vibration that mount pad can be test bolt provides condition, test bolt parts simultaneously and just can replace the axle and bearing that in prior art, bolt vibration test is used, thus can greatly alleviate the weight born needed for bobbing machine, thus just can on common vibration test machine the fastening self-locking nut vibration testing device of bearing of the vibration test of the fastening self-locking nut of complete matched bearings, reduce the production cost of the fastening self-locking nut of bearing.
Further, testing bolt adopts hollow bolt can alleviate the weight of test unit further; Test pad can make test condition more fit reality; The mounting portion of tabular and the base portion of strip can play the effect alleviating test unit weight equally, and because the vibration of most bobbing machine is straight reciprocating motion, mounting hole adopts elongated hole can reach the better fiting effect with bobbing machine.

Embodiment
The embodiment of the fastening self-locking nut vibration testing device of bearing, as Figure 1-5, the fastening self-locking nut vibration testing device of this bearing comprises mount pad 11, test bolt 12 and test pad 13.
Mount pad 11 comprises base portion and is located at the mounting portion in base portion, and base portion is for being fixedly assemblied in the worktable of bobbing machine by mount pad 11, mounting portion is used for assembling test bolt 12.In the present embodiment, base portion adopts list structure, its two ends place is respectively equipped with bolt hole, by penetrating bolt in bolt hole, mount pad is fixed during use, mounting portion is tabular, its thickness is consistent with the width of base portion and stand in base portion, adopts the mounting portion of platy structure to be to meet the weight alleviating mount pad 11 under the prerequisite that proof strength requires as far as possible.The mounting portion of mount pad 11 is provided with mounting hole, mounting hole 14 is for installation test bolt 12, test bolt 12 is loading after in mounting hole 14, it can be radially movable in mounting hole 14 when being subject to extraneous vibration, in the present embodiment, mounting hole 14 is specially the elongated hole on above-below direction, and test bolt 12 can be radially up and down in mounting hole 14.
Test bolt 12 is provided with tested nut construction section, tested nut construction section is provided with the spacing shoulder for coordinating with tested nut 15 block with the adjacent of the other parts of test bolt, in the present embodiment, the outline of test bolt 12 is multidiameter shape, spacing shoulder is made up of the step surface of the adjacent of the path Duan Yu great footpath section of multidiameter, and tested nut construction section has the path section of multidiameter to form.In addition, in the present embodiment, in order to alleviate the weight of test bolt to greatest extent, what test bolt 12 adopted is hollow bolt.
Test pad 13 for being fitted between tested nut 15 and described spacing shoulder, with the environment for use of the tested nut of maximized emulation.
When in use, mount pad fixedly can be assemblied on the worktable of bobbing machine, then test bolt is passed the mounting hole on mount pad, put test pad, finally tested nut screwing clamping is being tested on bolt, tested nut now does not compress the mounting portion of mount pad, opens bobbing machine and just can test.
