Problems solved by technology

In the above-mentioned sand making machine structure, the main shaft group is positioned and installed inside the main shaft seat on the frame. The main shaft group includes the main shaft box and the main shaft, and the main shaft is positioned inside the main shaft box through the bearing; however, its disadvantages are: 1. The main shaft The positioning effect of the box is not good, and it is prone to vibration and offset of the main shaft box, which affects the normal operation of the equipment; 2. The lack of stability of the main shaft generally exists in the main shaft group, which leads to potential safety hazards in the operation of the equipment; 3. The bearing seal of the main shaft group The effect is not good, and it is prone to oil leakage, dust inclusion, etc.; 4. The internal oil passage on the headstock is unreasonably set, resulting in inconvenient oil supply and affecting installation efficiency

Abstract

The invention relates to the field of mining equipment, and particularly relates to a main shaft structure on a vertical shaft impact type crusher. The main shaft structure comprises a main shaft base arranged on a rack and a main shaft assembly arranged on the main shaft base, wherein the main shaft assembly comprises a main shaft case and a main shaft which is positioned and arranged in the main shaft case. The main shaft structure has the advantages of stable positioning, good bearing seal effect, reasonable oil path arrangement and the like.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a main shaft structure on a vertical shaft impact crusher. Background technique [0002] In the field of mining equipment, the vertical shaft impact crusher is also known as the sand making machine. Its working principle is to divide the material into the throwing material in the middle and the blanking material in the surrounding area. It is thrown at high speed and collides with the surrounding falling materials, and the stones are broken by the way of "rock hitting rock". In the above-mentioned sand making machine structure, the main shaft group is positioned and installed inside the main shaft seat on the frame. The main shaft group includes the main shaft box and the main shaft, and the main shaft is positioned inside the main shaft box through the bearing; however, its disadvantages are: 1. The main shaft The positioning effect of the box is not good, and it is prone to vib...
