Embodiment Construction
[0021] Such as figure 1 , figure 2 As shown, an embodiment of a grease lubricated spindle shaft system, the spindle shaft system in this embodiment includes a housing 6 and a main shaft 1 that is rotatably assembled in the housing 6 through a bearing structure 7, the main shaft 1 extends along the front-to-back direction, In addition, the front end of the main shaft 1 is a protruding end extending out of the inner cavity of the housing 6, and the rear end of the main shaft 1 is located in the inner cavity of the housing 6. The front part of the housing 1 corresponds to the protruding end A sealing end cover 2 is provided, and the sealing end cover 2 has a perforation that is sleeved on the main shaft 1 with a gap. A sealing exhaust gap is left between the perforation and the main shaft 1. The shaft recess is provided with a spiral exhaust groove 21 for pumping and discharging the gas in the sealed exhaust gap toward the direction of the corresponding extension end of the mai...

The invention relates to a grease lubrication main shaft system which comprises a shell and a main shaft assembled in the shell in a rotating manner. The main shaft extends in the front-and-back direction and is provided with extending-out ends extending out of an inner cavity of the shell. The position, corresponding to the extending-out ends, of the shell is provided with sealing end caps. Each sealing end cap is provided with a through hole, the main shaft is sleeved with the through holes in a clearance manner, and a sealed exhaust gap is reserved between each through hole and the main shaft. The inner circumferential face of the through hole of each sealing end cap is provided with spiral exhaust slots coaxially, and the spiral exhaust slots are used for pumping and exhausting gas in the sealed exhaust gaps towards the corresponding extending-out ends of the main shaft in the rotating process of the main shaft. The outer circumferential faces of the sections, corresponding to the spiral exhaust slots, of the main shaft are smooth surfaces. Because the spiral exhaust slots are formed in the sealing end caps instead of the main shaft, the structure of the extending-out ends of the main shaft can be effectively simplified, the design and manufacturing cost of the main shaft is reduced, and the overall rigidity of the main shaft is improved.
Description
technical field [0001] The invention relates to a grease lubricated spindle shaft system. Background technique [0002] In the spindle shaft system, because the oil mist generated by oil lubrication is easy to pollute the environment, consume electricity and gas, at present, more and more manufacturers are turning their attention to the pollution-free and low-cost grease-lubricated spindle, but the grease-lubricated spindle The sealing problem is more troublesome. At present, since there is a rotation gap between the high-speed rotating main shaft and the end cover, in order to prevent the coolant and chip impurities from entering, a labyrinth seal is often provided at the rotation gap. However, in actual use and application, due to the vigorous injection of coolant during cutting, the labyrinth seal cannot completely block the entry of tiny chip particles entrained by the coolant, resulting in wear of the spindle, bearings and other components, and entering the interior of...
