Description
Technical field
It the utility model is related to a kind of improved machine oil refrigerating module housing.
Background technology
The pressure release mode generally use Inner of machine oil pump discharge lets out formula, the i.e. outlet when lubricating oil pump in traditional machine oil refrigerating module
When pressure exceedes pressure limiting valve opening pressure, pressure limiting valve is opened, and machine oil pump discharge is connected by drain path with oil inlet passage, high pressure
Oil returns to oil inlet passage by drain path, and hydraulic oil together enters rotor chamber after fully mixed with low pressure oil（See Fig. 1）.
But because machine oil cooling module structure limits, to save space, drain path is generally relatively near with rotor chamber distance, drain path
Hydraulic oil is often sufficiently mixed without the low pressure oil with intake channel and has just been directly entered rotor chamber, causes the huge punching to rotor
Hit, simultaneously because flow direction oily in the flow direction of drain path inner high voltage oil and rotor chamber is on the contrary, two strands of oil can produce strongly
Liquidate, produced in rotor chamber compared with maelstrom, not only easily produce cavitation, while easily cause oil suction difficult.Therefore, it is necessary to
A kind of rational structure is set to ensure product reliability of operation and stability.
Utility model content
The purpose of this utility model is to solve the above-mentioned problems of the prior art, there is provided a kind of improved machine oil is cold
But module housing, the housing can avoid impact of the drain path hydraulic oil to rotor.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：A kind of improved machine oil cooling mould
Block housing, the housing are provided with rotor of engine oil pump chamber, drain path, oil inlet passage, and the port of export of the drain path is close
The side of rotor chamber is provided with the gear oil dividing plate of extension, and the oily dividing plate of gear is " J " shaped, the bending direction of the oily dividing plate afterbody of gear
It is consistent with the machine oil flow direction in rotor chamber.
Preferably, the width in the drain path stage casing is more than the width of the port of export.
Preferably, the width of the drain path port of export is less than the width of the oil inlet passage port of export.
Further, a boss is provided with the oil inlet passage, oil inlet passage is divided into two by the boss, forms first
Oil inlet passage and the second oil inlet passage, the drain path port of export communicate with the first oil inlet passage, first oil inlet passage
The port of export communicates with the second oil inlet passage, and the second oil inlet passage port of export communicates with rotor of engine oil pump chamber.
Preferably, the drain path intersects with the first oil inlet passage in " people " font.
Preferably, the width of the first oil inlet passage port of export is less than the width of the second oil inlet passage port of export.
The beneficial effects of the invention are as follows：Because the port of export of drain path is provided with the gear extended oil close to the side of rotor chamber
Dividing plate, the oily dividing plate of gear is " J " shaped, and the machine oil flow direction in the bending direction and rotor chamber of the oily dividing plate afterbody of gear is consistent.
Such structure avoids hydraulic oil from being directly entered rotor chamber, it is necessary under with regard to drain path inner high voltage oil can be made to be obstructed by baffle plate
Side enters back into rotor chamber after being sufficiently mixed with imported oil, and this reduces impact of the hydraulic oil to rotor；Meanwhile dividing plate lower end
Direction is arranged to oil stream in rotor chamber to close warp architecture, oil-feed direction can be just directed to and the flow direction in rotor chamber
Unanimously, reduce and liquidate, reduce cavitation erosion risk.
In further technical scheme, by setting a boss in oil inlet passage, the boss is by oil inlet passage one
Be divided into two, the machine oil of oil inlet is divided into two bursts of tributaries, enters respectively from two passages, drain path machine oil only with the first oil-feed
Machine oil in passage is liquidated, and the machine oil in the second oil inlet passage, due to the reduction in the space that liquidates, is liquidated strong without influence
Degree is obvious to be weakened, and caused vortex phenomenon accordingly also weakens.By mixed machine oil for the first time before rotor chamber is entered with
Machine oil in second oil inlet passage further mixes, and vortes interference further reduces, so as to avoid lubricating oil pump oil suction difficulty, flow
Unstable stator and rotor produce the generation of phenomena such as cavitation erosion.
