Description

Technical field[0001]The present invention relates to the field of two-unit universal coupling transmission efficiency, torque, speed, and the like, and is specifically related to a large-angle closure dual universal coupling stage.Background technique[0002]At present, in the field of universal coupling efficiency test, it is often used in manual and increased load, and manual coupling efficiency testing is performed. The error is large, and it takes more time to test the load. It has the disadvantages of high consumption, inconvenient operation, number of angle adjustment, and other angle adjustment devices use flat surface swings, such asFigure 12 Structure Simplymap, when the angle deflection occurs, the distance between A and B is different, so that the parallel spacing of the entire loop changes, resulting in the gear to be unspected, no normal transmission, or using a stretching, resulting in low transmission accuracy; to overcome these Difficult, the present invention provide...

Problems solved by technology

[0002] At present, in the field of universal coupling efficiency testing, it is often carried out manually and by increasing the load. Manually testing the efficiency of the universal coupling has large errors and takes a lot of time. The method of increasing the load is used for testing. It has the disadvantages of high energy consumption, inconvenient operation, and few angle adjustment stages; in addition, the angle adjustment device adopts plane swing, such as Figure 12 Schematic diagram of the structure, when the angular deflection occurs, the distance between a and b is different, so that the parallel distance of the entire circuit changes, resulting in the failure of the gears to mesh and normal transmission, or the use of telescopic plane adjustment, resulting in low transmission accuracy; in order to overcome these Difficulties, the present invention provides a large-angle enclosed double-connected universal joint test bench, which has the advantages of low power consumption, simple operation, high degree of automation, infinite angle adjustment of universal joints, etc.
