Abstract

The invention provides a stirring tube driving speed reducer static test device. The stirring tube driving speed reducer static test device according to the invention comprises a support part, a test part, a plurality of force exertion elements and a control part, wherein the support part fixes and supports a speed reducer (20) to be tested, the test part comprises a carrying tube (22) and is connected with an output shaft of the speed reducer (20) to be tested, the force exertion elements comprise a torque loading device, a radial load loading device and an axial load loading device, and thecontrol part is connected to each force exertion element and controls each force exertion element for exerting preset load on the speed reducer (20) to be tested. The stirring tube driving speed reducer static test device according to the invention can comprehensively and precisely simulate various actual limit work conditions of the test speed reducer, the static intensity of each tested part inthe test speed reducer can be tested to find out weak links, and the reference basis is provided for the design.

Description

technical field [0001] The invention relates to product structure detection, in particular to a static test device for a mixing drum driven reducer. Background technique [0002] Static test, also known as static test, is mainly used to observe and study the strength, stiffness, stress and deformation distribution of product structure or components under static load, and to verify the correctness of product structure strength and static analysis. important means of sex. The loading system of full-scale structural static test is relatively complicated. Before the 1940s, lead grains or sand grains were used to simulate the distributed load of the product structure in bags during static tests; iron blocks were hung on ropes to simulate concentrated loads, and the method was simple. Later switch to electromechanical booster or hydraulic cylinder and jack for loading. Since the 1940s, full-scale structural static tests have been loaded through the lever system, and a multi-poi...
