Specific embodiment
The present invention is described further with reference to the accompanying drawing.
As shown in Figure 1 for turntable hydrostatic slideway etc. oil masses oil supply mechanism structural schematic diagram, be illustrated in figure 2 rotation
Platform hydrostatic slideway etc. oil masses oil supply mechanism schematic top plan view, including oil inlet pipe 2, oil pocket 4 and cover board 3, cover board 3 be fixed on oil
On chamber 4, oil pocket 4 is made of A chamber 41 and B chamber 42, and A chamber 41 is cylindrical cavity and B chamber 42 is annular cavity, and A chamber 41 is set
It sets in B chamber 42, A chamber 41 and B chamber 42 is concentric, and cover board 3 is mounted on Type B chamber, and cover board 3 and Type B chamber form closed cavity, A
Contour gap 5 is equipped between chamber 41 and cover board 3.
The center of cover board 3 is equipped with oil inlet pipe 2, and 2 one end of oil inlet pipe is protruded into A chamber 41, protrudes into the oil pipe distance A in A chamber 41
41 bottom of chamber is less than the one third of 41 height of A chamber.The side wall circumferential direction equidistantly distributed of B chamber 42 has multiple oil outlets 6, it is multiple go out
Oilhole 6 is located in same level, and each oil outlet 6 is respectively connected with fuel feed pump 8, and fuel feed pump 8 is by helix tube 81 and straight tube 82
Composition, one end of helix tube 81 are mounted on oil outlet 6, and the other end of helix tube 81 is connect with straight tube 82, and oil inlet pipe 2 is apart from out
Equal between oilhole 6, i.e., the length of every fuel feed pump 8 is identical as caliber.
Turntable hydrostatic slideway etc. oil masses oil supply mechanism method, comprising the following steps: step 1. open oil pump 1, lead to
It crosses oil inlet pipe 2 and oil is supplied to A chamber 41；
Step 2. oil inlet pipe 2 continues fuel feeding, and oil passes through inflow B chamber 42 after uniformly overflowing in gap 5 full of after A chamber 41；
After step 3. oil stream enters B chamber 42, the liquid level of the oil in B chamber 42 can be from the contour rising in bottom, by being uniformly distributed on B chamber 42
Oil outlet 6 be output to oil outlet 6, oil is output to fuel feed pump 8 again by oil outlet 6, and the length of different fuel feed pumps 8 is straight by adjusting
The spiral number of turns of the length of pipe 82 and helix tube 81 control, the spiral coil of the helix tube 81 in the longer fuel feed pump 8 of straight tube 82
