Abstract
The utility model relates to a channel type inclinable bush hydraulic bearing. The utility model can replace a high running grinding machine and a main shaft hydraulic bearing of other machines. One or a plurality of spiral channels and oil guiding wedges are positioned on a bearing shell of the inclinable bush hydraulic bearing. When the main shaft rotates, the lubricating oil flows into the oil guiding wedge first, then follows the spiral channel and passes through the load-bearing region. Therefore, the lubricating condition is bettered. The utility model facilitates the heat dissipation and reduces the abrasion between the shaft and the bearing and raises the service life.
Description
The groove type watt hydraulic bearing that can incline, the alternative grinding machine that runs up and other mechanical main shaft hydraulic bearing.
The existing watt hydraulic bearing that inclines, its three fan-shaped bearing shells are evenly distributed on around the mechanical main shaft neck, and the intrados of bearing shell is smooth, during the main shaft high speed rotating, lubricant oil forms three pressure oil film wedges, makes the self-alignment of main shaft energy, when load variations, the rotating center change is less.
The tilting-pad bearing gap is more little, its bearing capacity, oil film rigidity, rotating accuracy are just high more, but flow of lubrication is just more little, main shaft and bearing are easy to heating, and temperature rise is increased, so that " seize " phenomenon takes place, and when low-speed running, rub-moment is big, and tripping force is also big, and axle journal and bearing shell are easy to wearing and tearing.
The purpose of this utility model is to design a kind of bearing shell of the novel watt hydraulic bearing that inclines.Improve lubricating condition, reduce temperature rise and low speed friction moment, improve the working life of bearing shell and main shaft.
The utility model is to have opened one to several spiral grooves with draw oil film wedge on the bearing shell intrados of watt hydraulic bearing that can incline.Like this, when main axis rotation, lubricant oil is introduced into and draws oil film wedge, passes through supporting region along several spiral grooves again, thereby has improved the lubricating condition of main shaft and bearing shell.Help heat radiation, and reduced starting torque, significantly reduced the wearing and tearing of axle and bearing.
The utility model can make the gap of main shaft and bearing shell transfer forr a short time, thereby has improved the rotating accuracy of main shaft, has improved the oil film rigidity and the bearing capacity of bearing shell, has improved the working life of bearing shell and main shaft again greatly.
When grinding machine spindle has the light axial crackle and when not having the main shaft parts replacement, uses the utility model, but the extend normally main shaft used 7 months.
Fig. 1 is an embodiment of the present utility model.Fig. 2 is its plan view.Wherein 1 is bearing shell, the 2nd, and groove, the 3rd, draw oil film wedge.
Fig. 3 is several shapes of trench cross section.Fig. 4 is several shapes of drawing the oil film wedge cross section.
Drawing oil film wedge can be to count segmentation by groove.Fig. 5 is several forms of intermittently drawing oil film wedge.
Claims (4)
1, the groove type watt hydraulic bearing that can incline is applicable in grinding machine or other the mechanical spindle, is made up of three rectangle bearing shells, it is characterized in that having opened several spiral grooves and draw oil film wedge on the bearing shell intrados.
2, the groove type according to claim 1 watt hydraulic bearing that can incline, the sectional shape that it is characterized in that spiral grooves is rectangle, arc, triangle, trapezoidal is a kind of.
