Abstract

The invention relates to the technical field of gearboxes, in particular to a multi-stage gear gearbox which comprises an upper shell and a lower shell, a first rotating shaft and a second rotating shaft are rotatably connected in the upper shell and the lower shell, gears are fixedly connected to the first rotating shaft and the second rotating shaft, the two gears are meshed with each other, and the first rotating shaft and the second rotating shaft are fixedly connected to the upper shell and the lower shell. The device further comprises a bottom plate. A containing cavity is formed in the bottom plate and communicates with the interior of the lower shell, an extrusion plate is movably connected into the containing cavity, a through hole is formed in the extrusion plate, a first one-way valve is installed in the through hole, and a connecting rod is fixedly connected to the upper surface of the extrusion plate. According to the lubricating device for the gearbox, lubrication and heat dissipation of gears in the gearbox are achieved through lubricating oil, meanwhile, the lubricating oil in the upper shell and the lower shell flows into the dispersion pipe, and heat dissipation treatment of the lubricating oil is achieved.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a multi-stage gear gearbox. Background technique [0002] A gearbox is a gearbox that changes the transmission ratio and direction of motion. Located between the clutch and the central drive. According to the transmission type, the gear gearbox can be divided into two-shaft, three-shaft, and component types. The dual shaft type has two main shafts (not including the reverse gear shaft), which are reduced by only one pair of gears. The three-axis type has three main shafts (first shaft, intermediate shaft, and second shaft), which are reduced by two pairs of gears. The composition formula consists of two gearboxes connected in series or parallel in order to obtain more gears with fewer gears. [0003] In the process of using the existing multi-stage gear box, lubricating oil is injected into the box to lubricate and dissipate the gears. When the gearbox works for a long time...
