Abstract
The utility model relates to a full-floating bearing for a turbocharger. The full-floating bearing comprises a ring-shaped bearing main body and a bearing cavity, wherein the ring-shaped bearing main body is provided with an oil through hole; the oil through hole consists of an oil inlet end and an oil outlet end; the oil inlet end is arranged on the external circle surface of the ring-shaped bearing main body; the oil outlet end is arranged on the internal circle surface of the ring-shaped bearing main body; an inlet angle is formed from the oil inlet end to the oil outlet end and is 12-16 degrees. The full-floating bearing has the advantages that the oil through hole has certain angle, and engine oil flows into the floating bearing fully by means of centrifugal force (generating an oil absorbing effect), so that a rotor shaft is fully lubricated and cooled, the operation is smooth, and the pressurizing effect is obvious.
Description
Technical field
The utility model relates to a kind of full floating bearing, especially a kind of full floating bearing for turbosupercharger.
Background technique
Turbosupercharging is a kind of technology of utilizing internal-combustion engine (Internal Combustion Engine) to operate the exhaust gas driven air compressor (Air-compressor) producing.It,, to increase the air mass flow that enters internal-combustion engine, helps the more fuel of combustion in IC engine or makes fuel combustion more abundant, thereby improves working efficiency of internal combustion engine.
The exhaust gas turbine of turbosupercharger is High Rotation Speed under the promotion of waste gas, can produce a large amount of heat, and these heats can be delivered to the inside of intermediate.And there is floating bearing intermediate inside, the sufficient lubrication of its need of work machine oil, if lubricated insufficient, can cause rotor shaft serious wear, affects traveling comfort, and efficiency of turbocharger is reduced, and very person causes rotor shaft locking, and pressurized machine lost efficacy.
At floating bearing thin-walled, be provided with 6 place's oil throughs all over the body.Under working state, be filled with machine oil, can flow into more rapidly the matching surface of rotor shaft and floating bearing, form oil film, play lubrication.
The oil inlet end of existing oil channel hole does not have angle to oil outlet end, and rotor shaft, in the process of High Rotation Speed, owing to being subject to the effect of centrifugal force, can affect the ability that machine oil is lubricated, lowers the temperature parts by oilhole.
Model utility content
The utility model provides a kind of full floating bearing for turbosupercharger, the oil inlet end that has solved the oil channel hole of existing full floating bearing does not have angle to oil outlet end, rotor shaft is in the process of High Rotation Speed, owing to being subject to the effect of centrifugal force, can affect the problems such as ability that machine oil is lubricated, lowers the temperature parts by oilhole.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of full floating bearing for turbosupercharger, comprise ring bearing main body and bearing bore, on described ring bearing main body, be provided with oil through, wherein, described oil through is comprised of oil inlet end and oil outlet end, and described oil inlet end is arranged on the outer round surface of ring bearing main body, and described oil outlet end is arranged on the internal circular surfaces of ring bearing main body, there is inlet angle to described oil outlet end in described oil inlet end, the angle of described inlet angle is 12-16 degree.
Further, a kind of preferred version of the present utility model: the angle of described inlet angle is 14.8 degree.
Further, a kind of preferred version of the present utility model: the number of described oil through is 4-8.
Further, a kind of preferred version of the present utility model: the number of described oil through is 6.
The beneficial effects of the utility model:
The oil through of full floating bearing of the present utility model has certain angle, can make machine oil flow into fully floating bearing by centripetal force (producing the effect of oil suction), make rotor shaft lubricated fully, cooling, make running more steady, pressurized effect is more outstanding.
