Abstract

The invention discloses a gear impact bend simulation test method, which comprises impacting a toothed test sample clamped and loaded at the lower part of an impact bend test device through a pendulum hammer of the test device to obtain impact bend strength data, wherein the long side of the rectangular cross section of the stressed end of the test sample is matched with a pendulum hammer head blade, and an included angle of 30 degrees is formed between one side at the front end of test sample and the tangential line of the movement trajectory of the blade on the blade side. The invention also provides a gear impact bend simulation test device for the gear impact bend simulation test method. The inventive gear impact bend simulation test method has the characteristics of simple structure and accurate and rapid installation. The original simulation of the stress at one point in the middle of tooth width is changed to simulate the stress in the tooth width, which conforms more to the practice of line contact stress when gears is engaged, so that the obtained test data is more valuable as performance reference.

Description

technical field

[0001] The invention relates to a method and a device for a mechanical performance test, in particular to a method and a device for a bending test. Background technique

[0002] The invention is specially designed for clamping a specific sample in a simulated gear bending test. This test method was innovated by H.Brugge of ZF Company in Germany. In the gear manufacturing industry, the simple bending and punching test can replace the fatigue test of the gear. It is of great significance to evaluate the carburizing and quenching effect of gear steel and gear.

[0003] However, in the only literature, the test method introduced lacks an accurate and fast clamping method for bending and punching specimens in application. The present invention designs a ZBC2302-D metal impact testing machine manufactured by MTS Meister Industrial Systems (China) Co., Ltd., and the right anvil can be replaced to perform the bending impact test conveniently. It has been applied in...
