Split type gearbox

Abstract

The invention provides a split gearbox, comprising: a gearbox body, an oil tank body, an oil outlet pipe and an oil return pipe, the gearbox body and the oil tank body are connected through the oil outlet pipe and the oil return pipe, and the gearbox body includes a gear box cavity and a heat dissipation compartment , the driving gear and the driven gear, the heat dissipation compartment is attached to the cavity wall of the gear box, the driving gear and the driven gear are meshed in the gear box cavity, the fuel tank body includes the fuel tank cavity, heat insulation layer, oil outlet The oil outlet, the oil return port and the heater, the heat insulation layer is attached to the cavity wall of the fuel tank cavity, the oil outlet and the oil return port are arranged on the cavity wall of the fuel tank cavity, respectively communicated with the oil outlet pipe and the oil return pipe, and the heater is arranged on the bottom of the fuel tank cavity. The gearbox adopts a split structure, which reduces the volume and weight of the gearbox, keeps the gears inside the gearbox lubricated, reduces gear wear, and prolongs the service life of the gearbox. At the same time, it can lubricate the oil tank when the external temperature is too low The oil is evenly heated to improve the working efficiency of the gearbox.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to split gearboxes. Background technique [0002] The gearbox is an important part widely used in mechanical transmission. When a pair of gears mesh, due to the unavoidable errors such as tooth pitch and tooth shape, meshing impact will occur during operation, resulting in gear wear and gear meshing phase. the corresponding noise. At present, in the technical field of gearbox lubrication, the gearbox body is generally used as an oil tank for storing lubricating oil, that is, the lubricating oil is stored in the inner cavity of the gearbox, and the gear teeth are directly immersed in the lubricating oil. The characteristic of this structural design is that the gearbox is compact in structure, simple in design, and can use the oil stirring action of the gear teeth in the gearbox to play a lubricating role. However, the gear box with this structural design has the following disadva...

AI Technical Summary

Problems solved by technology

However, the gear box with this structural design has the following disadvantages: 1. This structural design needs to store more than 300 liters of lubricating oil inside the gear box, which will result in a larger volume and heavier weight of the gear box; 2. The oil stirring action of the gearbox makes a large amount of high-viscosity lubricating oil splash on the box wall of the gearbox, which can easily cause oil leakage in the gearbox. Oil loss seriously reduces the working efficiency of the gearbox; 3. When the gearbox is in a low-temperature environment, it is necessary to install a heater inside the gearbox to heat the lubricating oil. However, due to the limitation of the internal structure of the gearbox, setting the heater The quantity is small, and the power of each heater cannot be too large, so the heating performance of the lubricating oil is not ideal, and thus cannot meet the needs of the low temperature environment
