Aluminum alloy gearbox structure for high-speed railway

Abstract

The invention discloses an aluminum alloy gearbox structure for a high-speed railway. The aluminum alloy gearbox structure for the high-speed railway comprises an upper shell, a first installation hole, a connection bolt, a lower shell, a fastening bolt, a cross plate, a second installation hole, an oil conveying pipe, a convex head, a seal gasket, an insertion hole, a through hole, dirt storage grooves, a magnet, oil spraying openings, a base plate and an oil pump. The aluminum alloy gearbox structure for the high-speed railway has the beneficial effects that the bottom end in the lower shellis connected with the base plate and the fastening bolt, and various impurities and chips generated by lubrication during work can automatically flow to the lowest end in the lower shell and enter the fastening bolt at the lowest end; it is guaranteed that the impurities and chips cannot move along with the lubricating oil, the cleanness degree of the lubricating oil is guaranteed, the gear lubricating effect is better, too much friction is avoided, the impurities cannot exist between the gears, and the service lives of the gears are prolonged; the aluminum alloy gearbox structure for the high-speed railway has complete functions and can guarantee that the gears safely and efficiently work, and shell installation is convenient due to the insertion head and the insertion hole.

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
