Abstract

The invention discloses a cutting gear case with two side hydraulic oil ways. The cutting gear case comprises a case body, a base, planet carriers and high-pressure oil pipes. The base is arranged onthe case body and used for installing the cutting gear case, and oil inflow holes and oil return holes are formed in the two sides of the base. The planet carriers are arranged at the two ends in thecase body. The cutting gear case is provided with first oil inflow oil ways and first oil return oil ways, one end of each first oil inflow oil way is connected with the corresponding oil inflow hole,and each planet carrier is provided with a second oil inflow oil way connected with the other end of the corresponding first oil inflow oil way; and one end of each first oil return oil way is connected with the corresponding oil return hole, and each planet carrier is provided with a second oil return oil way connected with the other end of the corresponding first oil return oil way. The high-pressure oil pipes are connected with the planet carriers and comprise oil inflow cavities and oil return cavities, the oil inflow cavities communicate with the second oil inflow oil ways, and the oil return cavities communicate with the second oil return oil ways. By the adoption of the cutting gear case, high-pressure oil cylinders on the two sides can be independently controlled, the high-pressure oil pipes are provided with the oil inflow cavities and the oil return cavities at the same time, the structure is simplified, and the sealing performance is good.

Description

technical field [0001] The invention relates to the technical field of gear boxes, in particular to a cutting gear box with hydraulic oil passages on both sides. Background technique [0002] The main function of the built-in hydraulic oil circuit of the cutting gearbox of the bolter miner is to provide high-pressure support for the extension and loading of the hydraulic cylinders on both sides of the cutting gearbox, and to provide continuous and stable pressure output for the hydraulic cylinders. The built-in hydraulic oil circuit of the existing bolter cutting gear box has only one high-pressure oil inlet and return port, and supplies oil to the hydraulic cylinders on both sides at the same time. The disadvantages of the built-in hydraulic oil circuit arrangement of the cutting gear box are: [0003] 1. The independent control of the hydraulic cylinders on both sides of the gearbox cannot be realized; [0004] 2. When the oil flows from the main oil inlet to the branches...
