Technical Field
The invention belongs to the technical field of turbochargers, and particularly relates to a bearing body structure of a self-adaptive lubricating oil cooling turbocharger.
Background
The sealing structure is a weak link in the structure of the supercharger, and the service life of the supercharger is greatly determined by the service life of the sealing structure. The bearing body is an important component of the turbocharger and functions to support the floating bearing and the seal ring. The quality of the structural design of the bearing body directly influences the heat transfer effect of the bearing body, and further influences the working temperature of the sealing ring. The temperature of the part of the bearing body where the sealing ring blocks has an important influence on the service life of the sealing structure. The sealing ring stops the high temperature of platform position, makes the sealing ring lose elasticity easily, can not play sealed effect, and then leads to booster gas leakage, oil leak, makes the booster work reliably for a long time.
In order to solve the problem of overhigh working temperature of the sealing structure, a water-cooling bearing body structure is usually adopted, but the water-cooling bearing body has high processing cost due to complex structure and poor manufacturability, and meanwhile, a cooling water pipe needs to be arranged on an engine.

Therefore, the invention utilizes the working characteristic that the pressure of the lubricating oil is higher when the engine is in high speed and high load, the bearing body is provided with the cooling oil duct, one end of the oil duct is provided with the one-way pressure switch valve, the other end of the oil duct points to the sealing ring baffle table, when the exhaust temperature of the engine is higher, the one-way pressure switch valve is opened, and the lubricating oil cools the sealing ring baffle table. Specifically, the technical scheme of the invention is realized as follows:
the utility model provides a self-adaptation oil-cooling turbo charger bearing body structure, includes the bearing body, the whirlpool end sealing ring seat hole periphery department of bearing body is equipped with cooling water conservancy diversion annular, one side of bearing body is equipped with the cooling oil duct, the directional cooling water conservancy diversion annular of the terminal export of cooling oil duct, the other end entrance of cooling oil duct sets up one-way pressure switch valve, and when oil feed pressure exceeded a certain value of setting for, pressure switch valve was automatic to be opened, and lubricating oil sprays cooling water conservancy diversion annular department along the cooling oil duct.
Furthermore, the outlet at the tail end of the cooling oil duct and the cooling guide ring groove are arranged at intervals.
Furthermore, a lubricating oil inlet is formed in the middle of one side of the bearing body, and the lubricating oil inlet is communicated with a first lubricating oil channel which is communicated with the end of the compressor and the second lubricating oil channel which is communicated with the floating bearing structure in the bearing body.
Compared with the prior art, the invention has the following advantages:
