Abstract

The invention discloses a main shaft system of a vertical shaft type sand maker, comprising a main shaft and a shaft sleeve, wherein the main shaft is positioned in the shaft sleeve through a bearing; bearing covers combined by axial positioned bearings are arranged at the upper end and the lower end of the shaft sleeve; a sealing structure is arranged between the bearing cover and the main shaft; and a lubricating structure is arranged on the shaft cover and comprises a thin oil inlet, an oil return hole and a grease inlet which are arranged on the side wall body of the bearing cover. The main shaft system has reasonable, novel and unique structure and operates stably at high rotating speed; by lubricating and combining thin oil with grease, the problem that the main shaft is locked can be effectively solved and the service lives of the bearing and other parts can be prolonged; and in addition, during bearing assembly, the bearing sleeve is electromagnetically heated so as to ensure the assembly precision and bring convenience to the assembly process.

Description

technical field [0001] The invention relates to a vertical shaft type sand making machine assembly, in particular to a high-speed spindle system of the vertical shaft type sand making machine. Background technique [0002] The main shaft system is one of the key components in the vertical shaft sand making machine. Its function is to transmit torque, drive the rotor of the vertical shaft sand making machine to rotate, and support the rotor group. There is no unified standard for the structural design of the main shaft system of the vertical shaft sand making machine at home and abroad. The main shaft has various structures and adopts different assembly and lubrication methods. The lubrication methods include thin oil lubrication and grease lubrication. It is difficult to increase the speed of vertical shaft sand making machines on the market, the main shaft is easy to lock, and the oil temperature rises quickly. Contents of the invention [0003] The problem to be solved ...
