Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
From Fig. 1, Fig. 2 and Fig. 3, disk centrifuge high-speed bearing lubricating fitting of the present utility model, comprise vertical shaft 1, be set with connected body 2 and bearing support 10 on vertical shaft 1, also comprise fuel inlet fitting 3 and delivery connection 5, be disposed with disc 4, at least one upper bearing (metal) 6, spacer sleeve 8 and lower bearing 9 on vertical shaft 1 in described bearing support 10, spacer sleeve 8 is contained between upper bearing (metal) and lower bearing, gapped between spacer sleeve 8 and bearing support 10 inwalls.Be provided with lower lock nut 13 on the vertical shaft 1 of bearing support 10 lower ends, play the fixedly effect of lower bearing 9, lower lock nut 13 is gapped with bearing support 10 inner chambers, so that lubricant oil passes through smoothly.
Vertical shaft 1 end is connected with the belt pulley 14 mated with bearing support 10 by nut 16, belt pulley 14 belows are fixed with pulley cap 15, and belt pulley (14) is sleeved on the conical surface of vertical shaft 1 end.
Radially be provided with an oil inlet hole 20 that penetrates into upper bearing (metal) 6 on described connected body 2, oil inlet hole 20 1 ends communicate with fuel inlet fitting 3, and the other end penetrates into upper bearing (metal) 6; The upper-end surface of bearing support 10 is provided with the inclined hole 102 deviated with vertical shaft 1 axis, the upper end of inclined hole 102 and delivery connection 5 UNICOMs; Bearing support 10 lower ends in belt pulley 14 inner chambers are connected with oil skimming piece 11, and in the present embodiment, oil skimming piece 11 is fixing through screw 12.Be provided with oil skimming hole 110 on oil skimming piece 11, the linked hole 101 and inclined hole 102 UNICOMs of oil skimming hole 110 in being arranged on bearing support 10, gapped between oil skimming hole 110 and belt pulley 14 inwalls.
As visible as Fig. 3, Fig. 4, described oil skimming hole 110 radially radially deviates with vertical shaft 1.That is to say, on oil skimming piece 11 cross sections, place, oil skimming hole 110 Origin And Destination lines, vertical shaft 1 center and oil skimming hole 110 starting point lines, form one between this two line and be not equal to zero angle [alpha], its objective is and make lubricant oil can enter fast oil skimming hole 110, this angle α, between 15 to 75 degree, can reach oil-feed efficiency preferably, take 60 degree as best.
As shown in Figure 4, when the utility model is implemented, belt pulley 14 rotarily drives the lubricant oil rotating Vortex of inner chamber.Should guarantee during work that belt pulley 14 sense of rotation are contrary with oil skimming hole 110 offset directions, thereby further guarantee that lubricant oil enters, improve lubricated, radiating effect.
During disk centrifuge work, due to belt pulley 14 with vertical shaft 1 High Rotation Speed, lubricant oil in belt pulley 14 produces centrifugal force, raising along with rotating speed, the kinetic energy of oil converts potential energy to, lubricant oil is oil skimming hole 110 radially by oil skimming piece 11, oil circuit in bearing support 10 is got back to oil pump, lubricant oil in oil pump is by fuel inlet fitting 3, successively by disc 4, then successively by upper bearing (metal) 6, gap between spacer sleeve (8) and bearing support 10 inwalls, lower bearing 9, thereby upper bearing (metal) 6 and lower bearing 9 are lubricated, then lubricant oil continues to flow to belt pulley 14 inner chambers, get back to oil pump through the oil return circuit in the oil skimming piece.This oil circuit not only can constantly be transported to lubricant oil on the work bearing in a steady stream, and can effectively guarantee the normal operation of bearing with bearing running due to the amount of heat that High Rotation Speed produces, and has improved the operating life of bearing.The oil skimming hole 110 of departing from makes under belt pulley 14 rotation operating modes, and lubrication oil circulation is smooth and easy.
