Lubricating oil way structure of gear box

Abstract

The invention discloses a lubricating oil circuit structure of a gearbox, which enables the gearbox to be compact in structure and can reasonably lubricate a bearing and a gear of the gearbox. Comprising an upper box body, a lower box body and an oil pipe system, a low-speed shaft and a high-speed gear shaft are installed between the upper box body and the lower box body through bearings, an input gear is installed on the low-speed shaft and meshed with the high-speed gear shaft, an oil inlet is formed in one end of the lower box body, and an oil outlet and an oil injection port are formed in the inner wall of the lower box body. The oil pipe system is provided with an oil inlet pipe, an oil outlet pipe, an upper gear oil injection pipe and a lower gear oil injection pipe, the oil inlet pipe is communicated with the oil outlet, the oil outlet pipe is communicated with the oil inlet pipe and the oil injection port, and the upper gear oil injection pipe is communicated with the lower gear oil injection pipe. The upper gear oil spraying pipe sprays oil to the meshing position of the input gear and the high-speed gear shaft from the upper portion, and the lower gear oil spraying pipe sprays oil to the meshing position of the input gear and the high-speed gear shaft from the lower portion.

Description

technical field [0001] The invention relates to the technical field of gear gearboxes, in particular to a lubricating oil circuit structure of the gearbox. Background technique [0002] The transmission gearbox is an indispensable key component for the implementation of mechanical transmission in the equipment manufacturing industry, because the gear transmission has the advantages of high transmission precision, wide range of applicable transmission power, and can realize the transmission between any two axes in the space of parallel axes, intersecting axes, and staggered axes. , Gear transmission has been widely used in the development of metallurgy, electric power, construction machinery, energy and other industries. [0003] A complete set of gearboxes is often composed of key components such as box, gears, bearings and shafts. If the gear meshing transmission has poor lubrication effect, it will cause problems such as increased gear transmission power loss, high noise, ...

AI Technical Summary

Problems solved by technology

[0003] A complete set of gearboxes is often composed of key components such as the box body, gears, bearings, and shafts. If the gear meshing transmission is poorly lubricated, it will cause problems such as increased gear transmission power loss, high noise, and large vibration. Damage to the gear; if the lubrication effect of the bearing is not good, the surface temperature of the bearing pad will rise sharply, which will easily burn the bearing; in addition, because the lubrication of the gearbox needs to arrange the oil circuit, if the arrangement is not appropriate, the entire gearbox structure will be damaged. Messy, even seriously affecting the maintenance of the gearbox
