Abstract
The utility model relates to a bearing cover device, which has good oil returning ability so as to prevent oil leakage. The bearing covering comprises a bearing (1), a bearing body on the bearing (2); a bearing covering (3) and a sealed cover (4) which is arranged at the outer end of the bearing cover. A sealed ring is arranged between the sealed cover (4) and a main bearing (7). The utility model is characterized in that a plurality of oil returning holes (6) is arranged beneath the bearing cover (3).
Description
Technical field
The utility model relates to a kind of bearing cap device, is a kind of bearing cap device that is used for the turbocharger turbine end specifically.
Background technique
At present, the bearing cap below of the turbine end that reaches the turbosupercharger of using in the production of selling on the market has only a spill port, and its diameter is 2.2mm, so in actual use, lubricant oil is continuous productive set lubricant oil in the round groove of bearing cap, and finally the endoporus by bearing cap carries out axial flow to turbine end, so, lubricant oil passes through the seal ring on the sealing cover, has produced oil leakage phenomenon.
As mentioned above, there is following deficiency in prior art: the diameter of spill port is little, thereby flow area is little, makes that the oil return ability is poor, thereby can cause the appearance of oil leakage phenomenon.
Summary of the invention
The utility model has solved the bearing cap below of the turbine end of the turbosupercharger that prior art exists and has had only spill port, and the diameter of spill port is little, thereby circulation area is little, make that the oil return ability is poor, thereby the problem that can cause the appearance of oil leakage phenomenon, provide a kind of, prevented the bearing cap device that oil leakage phenomenon occurs by below the bearing cap of the turbine end of turbosupercharger, being provided with the ability that two bigger spill ports of diameter increase oil return.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of bearing cap device, the sealing cover that comprises bearing, bearing support, bearing cap and bearing cap outer end provided thereon, described sealing is placed on and is provided with seal ring between the main shaft, it is characterized in that described bearing cap below is provided with some spill ports.When pressurized machine normally moves, after the lubricant oil that comes self-supporter enters into bearing and is lubricated by the hole on the bearing support, collect lubricant oil by the round-end slots of bearing cap again, flow of lubricant is got back in the oil back chamber of support by some spill ports of being located at the bearing cap below then, after being provided with a plurality of spill ports, increased the oil return ability, reduced the productive set in the round groove of lubricant oil between bearing cap, reduced lubricant oil and passed through the ability of the endoporus of bearing cap to the turbine end axial flow, guarantee the validity of sealing cover and seal ring, stopped the phenomenon of turbine end leakage of oil when pressurized machine normally moves.
As preferably, described spill port is 2.So just increase flow area, reached the purpose that increases the oil return ability.
As preferably, the angle of the center line of described two spill ports is 8 °～12 °; The diameter of described spill port is 2.2～2.8mm.The center line of two spill ports in practice its angle with 10 °, diameter is good with 2.5mm, increased flow area like this, increased the oil return ability, reduced the productive set in the round groove of lubricant oil between bearing cap, reduced lubricant oil and passed through the ability of the endoporus of bearing cap, guaranteed the validity of sealing cover and seal ring, stopped the phenomenon of turbine end leakage of oil when pressurized machine normally moves to the turbine end axial flow.
The utility model is skillfully constructed, and is simple in structure, and utilization increases a spill port, and its diameter is become big, just reached the purpose that increases the oil return ability, and extended its working life.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation of bearing cap;
Fig. 3 is that the A-A of Fig. 2 is to schematic representation.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1, Fig. 2 and Fig. 3, this routine a kind of bearing cap device, the sealing cover (4) that comprises bearing (1), bearing support (2), bearing cap (3) and bearing cap outer end provided thereon, be provided with seal ring (6) between described sealing cover (4) and the main shaft (7), it is characterized in that described bearing cap (3) below is provided with two spill ports (6), the diameter of two spill ports (6) is that the angle of 2.5mm and its center line is 10 °.
When pressurized machine normally moves, after the lubricant oil that comes self-supporter enters into bearing and is lubricated by the hole on the bearing support, collect lubricant oil by the round-end slots of bearing cap again, by some spill ports of being located at the bearing cap below flow of lubricant is got back in the oil back chamber of support then.
Claims (5)
1, a kind of bearing cap device, the sealing cover (4) that comprises bearing (1), bearing support (2), bearing cap (3) and bearing cap outer end provided thereon, be provided with seal ring (5) between described sealing cover (4) and the main shaft (7), it is characterized in that described bearing cap (3) below is provided with some spill ports (6).
2, a kind of bearing cap device according to claim 1 is characterized in that described spill port (6) is 2.
