The invention discloses a multi-shaft linkage gearbox, which belongs to the technical field of combined tests for traction systems and aims to solve problems that combined test systems for the traction systems in the prior art are complicated, low in reliability and the like. The multi-shaft linkage gearbox comprises a box, a gear transmission component is arranged inside the box and comprises at least three transmission shafts including a first transmission shaft, a second transmission shaft and a third transmission shaft parallel to each other, transmission gear pairs are respectively arranged between the first transmission shaft and the second transmission shaft and between the first transmission shaft and the third transmission shaft, and two ends of the first transmission shaft, two ends of the second transmission shaft and two ends of the third transmission shaft extend out of the box to form six transmission ends. The multi-shaft linkage gearbox is used for one, two or four power plants to realize synchronous transmission, is particularly applicable to the combined test systems for the traction systems, wide in applicable range, simple in structure, easy to manufacture and low in cost, and substitutes for the complicated combined structure of multiple gear box systems in the prior art.
Description
technical field [0001] The invention relates to a comprehensive test technology of a traction system, in particular to a multi-axis linkage gearbox. Background technique [0002] With the deepening of technology introduction, the comprehensive test of the traction system of the domestically produced "Harmony" EMU has become particularly important. Various domestic research institutions will always face the difficulty of the test bench to meet the high-speed requirements of the "Harmony" when conducting comprehensive tests of the traction system. The test requirements for EMUs are mainly manifested in the fact that when testing the "Harmony" high-speed EMUs with technology introduction, it is necessary to test the performance parameters of four traction motors at the same time. The existing test benches in China can only meet the performance test requirements of a single traction motor. When testing four traction motors at the same time, it is necessary to combine multiple se...
