5、7 Superseding ARP5483/5 Rolling Element Bearing Test Method for Radial Limit and Fracture Load Testing RATIONALEARP5483/5A is being revised in association with the five-year document review to clarify test procedures and correct typographical errors in the text. 1. SCOPE This test method outlines th
6、e recommended procedure for performing static radial limit and ultimate load tests on rolling element bearings used in airframe applications. Bearings covered by this document shall be antifriction ball bearings and spherical roller bearings in either annular or rod end configurations. 2. REFERENCES

12、on of the test bearing. The load for each bearing size is specified in the applicable document. This load is the maximum load that should be applied to the bearing in application. RADIAL STATIC FRACTURE LOAD: The radial load equal to 1.5 times the Radial Limit Load, unless otherwise specified in the
13、 applicable document. Bearings subjected to this load shall be capable of being turned by hand and shall have no fractured components. BRINELL: Permanent deformation of a bearing raceway caused by a rolling element. Brinelling occurs when a bearing is subjected to a static load which causes the stre
14、ss in the ball contact area to exceed the yield stress of the material. 3. GENERAL REQUIREMENTS 3.1 Test Apparatus 3.1.1 Test Machine The fixture shall be mounted onto a test machine capable of applying the required load at a controlled rate. The calibration system for the machine shall conform to A
15、NSI/NCSL Z540-1 and ISO 10012. Its accuracy shall be verified every 12 months by a method complying with ASTM E4. The limit and ultimate loads of the test bearing shall be within the loading range of the testing machine as defined in ASTM E4. 3.1.2 Test Fixtures Dimensions of the test fixtures shall
16、 provide sufficient section thickness to assure rigid support of the test specimen when subjected to the fracture load. For threaded rod end bearings, the shank shall be mated with a fixture allowing a thread engagement of at least 1-1/2 times the thread pitch diameter. 3.1.3 Material The mounting a
17、pparatus shall be fabricated from steel and heat treated to a hardness of 40 HRC minimum. The test pin shall be fabricated from high strength tool steel or equivalent and heat treated to a hardness of 50 HRC minimum. 3.1.4 Mounting Fit Clearance between the mounting bolt and the inner ring shall be
18、0.0000 to 0.0010 inch or as specified in the applicable document. Clearance between the fixture and the outer ring shall be 0.0000 to 0.0010 inch or as specified in the applicable document.NOTE: The above approach for mounting the test bearing produces generally repeatable results by promoting stiff
19、 structural performance. The use of thin section fixtures or looser fits may result in significantly different results. 3.1.5 Measuring Equipment Inspection equipment shall be capable of measuring an indentation in the inner or outer ring raceway that is 0.0005 times the rolling element diameter.
