Description
Technical field
The present invention relates to turbo-charger technical field, particularly a kind of bearing support used in turbosupercharger.
Background technique
Along with the high speed development of supercharging technology in recent years, the increasing extent that turbosupercharger is employed is wide, after but motor adopts supercharging, its delivery temperature improves greatly, can reach more than 1000 degree, therefore the bearing body structure designed, needs the heat load of shielding whirlpool end and is not passed to bearing arrangement and whirlpool end seal ring.In the design of traditional bearing support, there is cooling water chamber coordinate lubricant oil cooling and be not with cooling water chamber only to cool two kinds by lubricant oil, by the oil cooled bearing support of lubrication as shown in Figure 1, oil inlet hole 1 on bearing support is connected with main oil-hole 2, main oil-hole 2 is provided with Oil Guide inclined hole 3 and Oil Guide inclined hole 7, Oil Guide inclined hole 3 and Oil Guide inclined hole 7 communicate with bearing hole 4 respectively, bearing hole 4 communicates with main oil pocket 6, and the bottom of main oil pocket 6 is provided with oil outlet 5.As shown in Figure 2, bearing support is connected with turbine box 10 by bolt its using state, installs a collet 11 between bearing support and turbine box 10, and whirlpool end seal ring 12 is arranged in rotating shaft 15, prevents lubricant oil from entering in turbine box 10 from the turbine end of bearing support.Lubricant oil enters main oily straight hole 2 by oil inlet hole 1, then by Oil Guide inclined hole 3 and Oil Guide inclined hole 7 be sliding bearing 13, sliding bearing 13 provides lubrication, enter main oil pocket 6 again to be discharged by oil outlet 5, make whole bearing support particularly its turbine end reach cooling effect.Collet 11 intercepts the turbine end of the combustion gas in turbine box 10 and bearing support and opens, combustion gas is made not enter bearing support, thus reduce combustion gas because transmission of heat by contact and thermal radiation are to the heat transfer of bearing support, the temperature of bearing support is made to be unlikely to too high, ensure that the cooling and lubricating effect of lubricant oil, also ensure that the seal action that whirlpool end seal ring 12 is good simultaneously.But due to collet 11, bearing support, the material of several part of turbine box 10 is different, at high temperature the thermal expansion coefficient of various material is different, therefore after the change of long-term alternation heat load, matching gap between collet 11 and bearing support and turbine box 10 can change, gas leakage can be caused, high-temperature fuel gas in turbine box 10 can enter the whirlpool end of bearing support from air-leak section, make the increase in temperature of bearing support turbine end, thus cause whirlpool end seal ring 12 at high temperature to work, because whirlpool end seal ring 12 is rubber parts, work easy carbon deposit and wearing and tearing at high operating temperatures, produce leakage of oil.Meanwhile, due to the increase in temperature of bearing support turbine end, make the increase in temperature of whole bearing support, the cooling and lubricating effect of lubricant oil declines, and is unfavorable for that turbosupercharger is well run, reduces the working life of turbosupercharger.
Summary of the invention
The purpose of this utility model be overcome prior art above-mentioned deficiency and a kind of turbocharger bearing body that can reduce turbocharger bearing body turbine end temperature is provided.
The technical solution of the utility model is: a kind of turbocharger bearing body, oil inlet hole on bearing support is connected with main oil-hole, main oil-hole is provided with Oil Guide inclined hole and Oil Guide inclined hole, Oil Guide inclined hole and Oil Guide inclined hole communicate with bearing hole respectively, bearing hole communicates with main oil pocket, and the bottom of main oil pocket is provided with oil outlet.
Be provided with an oil guiding hole in one end of main oil-hole, oil guiding hole communicates with main oil pocket, and the diameter of oil guiding hole is less than the diameter of main oil-hole.
During turbocharger operation, a part of lubricant oil in main oil-hole directly enters main oil pocket from oil guiding hole, cools the turbine end of bearing support, takes away more heat, and bearing support lubrication system is stably worked.
Further technological scheme of the present utility model is: in the below of main oil pocket near oil guiding hole, be provided with the step of a cross section semicircular in shape, and by step, main oil pocket top is partitioned into a small oil cavity, small oil cavity communicates with main oil pocket.
The effect of step prevents the lubricant oil entering main oil pocket from oil guiding hole to be sprayed directly on to whirlpool end seal ring, prevents lubricant oil from revealing from here.
During turbocharger operation, a part of lubricant oil in main oil-hole directly enters small oil cavity from oil guiding hole, then enters main oil pocket from small oil cavity, cools the turbine end of bearing support, takes away more heat, and bearing support lubrication system is stably worked.
The utility model compared with prior art has following features:
1, the main oil-hole on bearing support is communicated with main oil pocket by oil guiding hole, better can cool bearing support and whirlpool end seal ring, and the temperature that can better reduce due to bearing portion when heat flows backwards raises, under whirlpool end seal ring can being made to be in lower operating temperature for a long time, reach good sealing effect simultaneously.
2, upper design one step of main oil pocket, effectively can stop lubricant oil directly to enter seal ring place and cause oil leak.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
