Therefore need a kind of novel electric main shaft of exploitation, the lubricating system of its main shaft bearing is that water or water smoke are lubricated, even water is as lubricant medium.Water replaces grease or oil to make lubricant medium; Not only can practice thrift a large amount of oil plants; Can also avoid with grease or oil is the lubricant medium pollution on the environment, and can be applied to environment is had the industry such as food, medicine, material of specific (special) requirements, has expanded the range of application of electric main shaft.
Summary of the invention
The objective of the invention is to solve the drawback of lubricant medium contaminated environment in the lubricating systems such as existing various common electrical main shaft greases, mist of oil, oil gas; And provide that a kind of cost is low, the water of environmentally safe is as the water or the lubricated electric main shaft of water smoke of lubricant medium; When realization is carried out effectively lubricating to electric mainshaft bearing; Minimizing is to the pollution of environment, makes electric main shaft can be adapted to environment is had the industry such as food, medicine, material of specific (special) requirements.
To achieve these goals, technical scheme of the present invention is: the electric main shaft that a kind of water or water smoke are lubricated, and it comprises electric main shaft shell, is arranged on electric main shaft shell interior rotating shaft, motor stator and is arranged on rotor and the bearing assembly in the rotating shaft; It is characterized in that; On said electric main shaft shell and bearing pedestal, have the water or the water smoke that make lubricant medium and get into the inner lubricant medium passage of realizing bearing lubrication of main shaft bearing; On electric main shaft shell, be provided with cooling chamber, on electric main shaft shell, also be provided with the cooling duct that is used to feed the cooling of the internal dress of cooling fluid realization motor stator near inner electric machine stator position.
Further, said bearing pedestal comprises front-end bearing pedestal that is installed in electric main shaft shell front end and the rear bearing block that is arranged on electric rear-end of spindle, on described forward and backward bearing pedestal, all makes the lubricant medium passage.
Further, said end cap comprises the front end housing that is arranged on the front-end bearing pedestal and is arranged on the rear end cap on the rear bearing block, on described rear end cap, has the lubricant medium passage.
Further; The O RunddichtringO of seal sleeve also being installed between said motor stator and rotor and being arranged on the seal sleeve end; Through between the stator of electric main shaft inner electric machine and rotor, adding the mode that seal sleeve and O RunddichtringO are installed; Realize the internally sealing of dress motor stator, prevent to get into the inner electric machine stator winding and reduce its insulation property, guarantee the working condition that it is normal and safe as the water or the water smoke of lubricant medium.
The present invention has beneficial effect compared with prior art:
The present invention as lubricant medium, has changed the common electrical main shaft with grease or oily conventional lubrication mode as lubricant medium with water; Not only help economizing on resources, reducing cost, and environment is not produced pollution, meet requirement on environmental protection; And it is applied widely, is particularly suitable for environment is had the use of the industry such as food, medicine, material of specific (special) requirements.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment;
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with embodiment, further set forth the present invention.
Embodiment:
Referring to Fig. 1, the electric main shaft that a kind of water of the present invention or water smoke are lubricated, it comprises electric main shaft shell 11, be arranged in the electric main shaft shell 11 rotating shaft 1, motor stators 10 and be arranged on rotor 9 and the bearing assembly in the rotating shaft 1; This bearing assembly comprises fore bearing assembly 4,6 and rear bearing assembly 14,16, and front and back nut 2,18 is realized fore bearing assembly 4 and 6, rear bearing assembly 14,16 are carried out fixing and locking.On said electric main shaft shell 11 and bearing pedestal, have the water that makes lubricant medium or water smoke and get into the inner lubricant medium passage of realizing bearing lubrication 20 of main shaft bearing, water or the water smoke used as bearing lubrication through the lubrication channel supply; Between inner electric machine rotor 9 and motor stator 10, add the O RunddichtringO 7,13 of seal sleeve 8 being installed and being arranged on the seal sleeve end; Realize the internally sealing and the protective effect of dress motor stator 10, avoid getting into electric main shaft inner electric machine stator 10 as the water or the water smoke of lubricant medium; And then reduce the inner electric machine stator winding insulation even burn out the problem of inner electric machine stator winding, guarantee the working condition that it is normal and safe.
