Description

Gear dismounting device of high-rotation-speed gear box for oil experiments Technical Field The application belongs to the technical field of gearboxes, and particularly relates to a gear dismounting device of a high-rotation-speed gearbox for oil experiments. Background The gear box is used as an energy transmission device widely applied in mechanical equipment, and the design level of the gear box reflects the comprehensive national force and the industrial technical level of a country to a certain extent. With the rapid development of science and technology, higher requirements are also put forward on various performances of the gear box, the performances of the gear box directly affect the efficiency and reliability of the whole system, and the gear box needs to work under the working conditions of high speed and high load. Thus, the performance of the lubricating oil is also required to be extremely high. The lubricating oil is required to have not only good lubrication to reduce wear but also good cooling performance to prevent overheating. The lubrication state of the gearbox directly affects the life of the gears and the stability of the overall system. In the field of oil test stands, testing of gearboxes has been focused mainly on the evaluation of the effects of lubricating oil on gears and the performance of lubricating oil. The viscosity, density and oil content of the lubricating oil have a direct impact on the churning losses, friction losses and cooling effects of the gearbox. Churning losses are an important part of the total power loss of the gearbox, accounting for about 30%. Therefore, research and optimization of the lubrication system of the gearbox, reduction of oil stirring loss, and great significance in improving the efficiency of the gearbox and reducing energy consumption are achieved. Currently, high speed gearboxes for oil testing have the disadvantage of inconvenient gear removal by unpacking, because the gearbox design may not take frequent disassembly requirements into account, resulting in complex and time-consuming disassembly procedures, which increase the difficulty of maintenance and inspection, especially when rapid gear replacement or troubleshooting is required. In addition, the problem of the misalignment of the box and the gear shaft after the gear is disassembled is also caused, and the misalignment is possibly caused by the manufacturing tolerance, abrasion or assembly errors of the box structure in the disassembling process of the gear box, and the misalignment can cause the unstable operation of the gear box, increase vibration and noise, cause bearing abrasion and reduce the service life and efficiency of the gear box. Therefore, to ensure that the case is concentric with the gear shaft, the case is fixed after being disassembled, and the gear case is usually fixed precisely to ensure the stability and the accuracy of the position coordinates during operation. However, the existing fixing tool cannot adapt to all types of gear box shells, or the shells may be damaged in the fixing process, particularly under the condition that the shell walls are thin, and the position of the shells may be changed, so that not only is the tightness of the gear box affected, but also lubricating oil leakage is possibly caused, and the accuracy of an oil product test and the performance of the gear box are further affected. Because of the above problems, the gear case is worn and damaged due to the non-concentricity caused by frequent disassembly and replacement of the gears, which requires additional cost, and is disadvantageous for continuity and economy of the oil test. Disclosure of utility model In view of the above, the application aims to provide a gear dismounting device of a high-rotation-speed gear box for oil experiments, which aims to solve the problems that when the high-speed gear box is used for oil experiments, the gear is inconvenient to detach after being opened from a box, the gear detaching process is complex and time-consuming, and the gear box shell is difficult to accurately fix in the detaching process, so that the gear box shell and a gear shaft cannot be ensured to be concentric, the operation of the gear box is unstable, vibration and noise are increased, bearing abrasion is caused, and the service life and efficiency of the gear box are reduced. In order to achieve the above purpose, the technical scheme of the application is realized as follows: The application provides a gear dismounting device of a high-rotation-speed gear box for oil experiments, which comprises a shell, an end cover fixedly connected with the shell, and a gear train assembly correspondingly arranged on the shell and the end cover, wherein the gear dismounting device further comprises: The positioning members are at least two in number and comprise positioning pins and positioning plugs, the positioning pins are arranged on the shell, the positioning plugs are arranged on the end
