Abstract

The invention relates to the field of mine equipment and particularly relates to a main shaft group on a vertical shaft impact type crusher. The main shaft group on the vertical shaft impact type crusher comprises a main shaft box, and a main shaft for positioning and mounting the main shaft box. The main shaft group has the advantages of good main shaft stability, good sealing effect and reasonable sliding structure.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a main shaft group 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 existing sand making machine structure, the main shaft group includes the main shaft box and the main shaft. 2. The sealing effect of the bearing of the main shaft group is not good, which is prone to oil leakage and dust inclusion; 3. The internal oil passage on the main shaft box is unreasonably set, which leads to inconvenient oil supply and affects the installation efficiency. Contents of the inventi...
