A gear single tooth loading test device with load equalization function

Abstract

A gear single-tooth loading test device with a load equalizing function, including two parts: a supporting structure and a loading structure located above the supporting structure; the supporting structure includes a supporting head, an adjusting gasket, a supporting base, a positioning ring, and a supporting frame , mandrel, shaft gland; the lower end of the support head is fixed on the support base; the support frame is located on one side of the support head, and the test gear is installed on the top of the adjustable bracket through the positioning ring, the mandrel and the shaft gland; The loading structure includes an indenter base, a limiting sleeve, a self-adjusting indenter and a loading circular plate arranged in sequence from top to bottom coaxially with the supporting head; the indenter base and the limiting sleeve are passed through The connectors are fixed together; the self-adjusting indenter is seated in the limit sleeve, and the convex cylindrical surface at the upper end forms a freely rotatable fit with the indenter base and the concave arc surface of the limit sleeve ; The loading circular plate is fixed on the lower end of the self-adjusting pressure head through anti-off screws.

Description

technical field [0001] The invention relates to a gear root bending strength test device, in particular to a gear single-tooth loading test device with a load equalizing function, which can be applied to the check of the static strength of the gear and the test of the tooth profile stiffness , group tests of material ultimate stress, evaluation of the influence of tooth root geometry on bending strength, and checking of gear tooth bending bearing capacity, etc. The test data and judgment conclusions obtained can provide design basis for the development of new products. The basic application technology category of gear transmission. Background technique [0002] The checking of dedendum bending strength is an important part of the development of new gear transmission products. At present, the calculation of tooth root bending strength in the gearbox design process is carried out in China according to the national standard GB / T3480-1997, which is equivalent to the internation...

Problems solved by technology

However, with the continuous development of gear products in the direction of light weight, long life and high reliability in recent years, the problem of lack of basic test data in the process of gear transmission design in my country has become more obvious, and the development of my country's high-end gear products has been severely constrained

This problem is mainly reflected in the following two aspects: First, there are certain differences between domestic and foreign countries in terms of alloy composition, smelting level, and heat treatment capacity of gear materials. Applying the test data of foreign gear materials for product development will result in large Second, the standard is the test data of more than 20 years ago. With the continuous emergence of new materials and new processes in recent years, there is an urgent need for test data that meets the current gear manufacturing level.
