Aluminum alloy gearbox structure for high-speed railway

Abstract

The invention discloses an aluminum alloy gear box structure for high-speed rail, which comprises an upper shell, a first mounting hole, a connecting bolt, a lower shell, a fastening bolt, a horizontal plate, a second mounting hole, an oil delivery pipe, a protruding head, Gaskets, sockets, through holes, sumps, magnets, fuel injection ports, backing plates and oil pumps. The beneficial effect of the present invention is: by connecting the backing plate and fastening bolts at the inner bottom of the lower shell, various impurities and debris generated by lubrication during work can automatically flow to the innermost end of the lower shell, and enter at the lowest end into the fastening bolt. Ensure that impurities and debris will no longer move with the lubricating oil, ensuring the cleanliness of the lubricating oil, making the gear lubrication effect better, not generating too much friction, impurities will not be mixed between the gears, and the service life of the gears extend. The gear box has complete functions, which can ensure the safe and efficient operation of the gears, and the protrusion and the socket are convenient for the installation of the housing.

Description

technical field [0001] The invention relates to a gear box structure, in particular to an aluminum alloy gear box structure for high-speed rail, and belongs to the application field of gear boxes. Background technique [0002] With the continuous development of science and technology, my country's transportation industry has been rapidly improved. From steam trains to ordinary trains to the current high-speed rail, it marks the continuous progress of my country's railway technology. There are various components on the high-speed rail. In order to reduce the weight of the car body itself and improve the performance of use, aluminum alloy gearbox structures are often used on high-speed rail. [0003] However, the existing aluminum alloy gearbox structure for high-speed rail still has some deficiencies in use. The existing aluminum alloy gearbox structure for high-speed rail has a single function, and the internal gear lubrication effect is limited. When there is less lubrica...

[0003] However, the existing aluminum alloy gearbox structure for high-speed rail still has some deficiencies in use

The existing aluminum alloy gearbox structure for high-speed rail has a single function, and the internal gear lubrication effect is limited. When there is less lubricating oil, the normal operation of the gear is affected and the operation of the gear is unfavorable.

Moreover, the impurities generated during the gear work cannot be removed, which affects the service life of the gear
