Rubber bearing life test clamp

Abstract

The invention discloses a rubber bearing life test clamp, which comprises a base body, a first fixed base plate, a second fixed base plate, a first movable base plate, a second movable base plate, a dynamic loading bolt and static load preload nuts. The outer edges of the first fixed base plate and the second fixed base plate are fixedly arranged on the base body; the bottom end of the dynamic loading bolt passes through the first fixed base plate, the second fixed base plate, the first movable base plate and the second movable base plate in sequence; and one of the static load preload nuts is locked under the second movable base plate, and the other nut is locked on the first movable base plate. The clamp is provided with an inverted test station and a normal test station, so that the clamp can provide clamp and load applying test functions for two or more rubber bearings simultaneously; the dynamic loading bolt is connected with a universal tester, so that static load and alternating load can be applied to the rubber bearing simultaneously, and test effect is good; and the clamp is ingenious and compact in whole structure design, convenient to install and easy to disassemble.

Description

technical field [0001] The invention relates to a rubber bearing test tool, in particular to a rubber bearing life test jig. Background technique [0002] Rubber bearings have the advantages of large elastic range, high damping, and good adhesion to metals. They have been widely used in the support of various mechanical equipment such as air compressors, diesel engines, gasoline engines, water pumps, and electric welding machines. During the use and storage of rubber, it is affected by factors such as temperature in the environment, radiation, and external alternating, random or sudden pressure, especially under the deformation conditions caused by thermal oxygen, light oxygen, and external forces, the properties of rubber materials will change. decline over time, aging failures and fatigue failures occur, leading to system failure. In order to ensure the reliability and safety of power equipment and the economy of use and maintenance, and accurately predict the reliable li...
