Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, the present utility model provides the following technical solutions: the utility model provides a dual-purpose main shaft seal structure stands and crouches, including main shaft housing 1, install high-speed gyration main shaft 2 in the main shaft housing 1, install interior spacer 3 and outer spacer 4 in the main shaft housing 1, outer spacer 4 sets up in interior spacer 3 outsidely, high-speed gyration main shaft 2 sets up in interior spacer 3 inside, high-speed bearing 5 is installed to the one end of interior spacer 3 and outer spacer 4, tear bearing spacer 6 open is installed to one side of high-speed bearing 5, flange 7 is installed to one end of main shaft housing 1, install the gland on one side of flange 7, be provided with pressure release cavity 8 between flange 7 and the high-speed gyration main shaft 2, flange 7 passes through bolted connection with main shaft housing 1, lubricating material 9 has been paintd to the junction of high-speed gyration main shaft 2 and flange 7, lubricating material 9 is made for polyurethane material, contact zero clearance cooperation between lubricating material 9 and the high-speed gyration main shaft 2.
Specifically, the pressure release cavity 8 that makes through setting up the high-speed main shaft 2 can not produce the negative pressure in its inside when high-speed rotation, and then avoid high-speed main shaft 2 high-speed rotation to inhale inside with water and cause inside damage, can make high-speed main shaft 2 carry out self-lubricating through the lubricating material 9 of painting to realize main shaft and gland clearance fit, and then cooling water and other impurity are no matter how main shaft 2 is swung in high-speed rotation, can't get into the main shaft bearing inside, and then avoid the main shaft damage.
