The technical scheme that provides according to the utility model, the two ends rotating turret of main shaft is located on the frame, and be fixed with grinding wheel chuck at an end of main shaft, the other end of main shaft is equipped with off-load belt pulley and drive plate, the off-load belt pulley is installed on the main shaft by rolling bearing, this drive plate and main shaft are fixedlyed connected one by key, the off-load belt pulley is by the drive plate drive shaft, main shaft is installed in the rack sleeve by left hydrodynamic bearing bearing shell and right hydrodynamic bearing bearing shell, the axial location of main shaft is located by single direction thrust ball bearing, on rack sleeve, be provided with and be used for lubricated left hydrodynamic bearing bearing shell, the lubricating cavity of right hydrodynamic bearing bearing shell and main shaft is provided with the oil inlet pipe and the flowline that are connected with lubricating cavity on the rack sleeve at lubricating cavity place.
The utility model bearing clearance is easy to adjust, and is easy to maintenance, lubricates, and makes integral rigidity better.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the two ends rotating turret of main shaft 05 is located on the frame, and an end therein is fixed with grinding wheel chuck 01, the other end is equipped with off-load belt pulley 03 and drive plate 11, off-load belt pulley 03 is installed on the main shaft 05 by rolling bearing 10, this drive plate 11 and main shaft 05 are fixedlyed connected one by key, off-load belt pulley 03 is by drive plate 11 drive shaft 05, main shaft 05 is installed in the rack sleeve 12 with right hydrodynamic bearing bearing shell 07 by left hydrodynamic bearing bearing shell 04, the axial location of main shaft 05 is by single direction thrust ball bearing 09 location, on rack sleeve 12, be provided with and be used for lubricated left hydrodynamic bearing bearing shell 04, the lubricating cavity 02 of right hydrodynamic bearing bearing shell 07 and main shaft 05, after making that main shaft 05 rotates, dynamic pressure oil film be can form between main shaft 05 external diameter and left hydrodynamic bearing bearing shell 04 and the right hydrodynamic bearing bearing shell 07 to bear load, the oil inlet pipe 06 and flowline 08 that are connected with lubricating cavity 02 on the rack sleeve 12 at lubricating cavity 02 place, are provided with.
During use, its emery wheel is installed on the main shaft 05 by grinding wheel chuck 01, main shaft 05 is installed in the rack sleeve 12 with right hydrodynamic bearing bearing shell 07 by the left hydrodynamic bearing bearing shell 04 that is distributed in two ends, left side hydrodynamic bearing bearing shell 04 all is long bearing shells with right hydrodynamic bearing bearing shell 07, form by five at circumferencial direction, wherein cutting force mainly carries the left hydrodynamic bearing bearing shell 04 of direction or two bearing shells in the right hydrodynamic bearing bearing shell 07 pass through Bolt Connection, make back of bearing directly contact with bearing inner casing hole line, and be that the contact of long bearing shell so line is longer, the point contact rigidity that the short bearing shell bulb of comparing supports is better, certainly also higher to the linearity required precision of rack sleeve 12 endoporus, its adjustment screw of three bearing shells that can adjust main shaft 05 center and main shaft 05 and left hydrodynamic bearing bearing shell 04 or right hydrodynamic bearing bearing shell 07 gap in addition neither support by bulb, but three bolt surface bearings at the remaining three bearing shell back sides in left hydrodynamic bearing bearing shell 04 or right hydrodynamic bearing bearing shell 07, its bearing length of short bearing shell of comparing like this is longer, and rigidity is better.The axial thrust of main shaft 05 is by single direction thrust ball bearing 09 carrying axial force.The radial load of rolling bearing 10 carrying off-load belt pulleys 03, off-load belt pulley 03 connects with main shaft 05 by drive plate 11, and moment is delivered on the main shaft 05 stably.Oil inlet pipe 06 is responsible for to main shaft 05 fuel feeding, is full of lubricating oil and is discharged by flowline 08 later in left hydrodynamic bearing bearing shell 04 and right hydrodynamic bearing bearing shell 07.So just can guarantee that left hydrodynamic bearing bearing shell 04 obtains just starting main shaft 05 after the sufficient lubrication with right hydrodynamic bearing bearing shell 07.
