Description
Technical field
The invention belongs to the transmission test technical field of engineering machinery, farm machinery, particularly relates to a kind of oil level holding device of wheel box test run.
Background technology
Along with the fast development of global economy, the market demand of engineering machinery, farm machinery also constantly increases.The important component part into engineering machinery, farm machinery pretended by wheel box, after having assembled, must carry out test run test.In test run process of the test, be a committed step to the flushing of casing, lubrication.The foreign material such as iron filings remaining in casing, the grains of sand can be cleaned out by purge oil, can play again lubrication, cooling effect, ensure that the serviceable life of wheel box.
At present, domestic existing test method opens stifled for the oil of oil drain hole bottom wheel box at the trial, the purge oil flowed in wheel box will all flow out simultaneously, in this course, the purge oil of flowing can not flow through the position needing to rinse and cool fully, and the parts such as wheel box annular wheel can not rinse fully and lubricate, cool.If wheel box can not rinse fully, residual foreign will affect the serviceable life of wheel box; And, if the parts such as commissioning process middle gear, bearing can not sufficient lubrication, cooling, will likely damage.
Summary of the invention
The invention provides a kind of oil level holding device of wheel box test run for solving in known technology the technical matters that exists, and this technical scheme can solve the irretentive problem of oil level in existing wheel box test run process of the test.
A kind of oil level holding device of wheel box test run, comprise S shape pipe, guide pipe and inverted-loop tube, it is characterized in that: one end of S shape pipe is inserted in oil drain hole, the S shape pipe position be inserted in oil drain hole is set with O RunddichtringO first, this end of S shape pipe is also provided with the spacing axle collar that restriction S shape pipe inserts the degree of depth in oil drain hole in the outside of tube wall, the other end of S shape pipe is communicated with one end of guide pipe, magnetic filter is provided with and magnetic blocks up in S shape pipe and the connectivity part of guide pipe, inverted-loop tube is inserted in guide pipe, can move up and down in inside, be sealed by O RunddichtringO second.
The advantage that the invention has and good effect are:
Because the invention adopts technique scheme, make use of characteristic and the law of connected vessels of fluid flowing, ensure that the Height of oil in this device is identical with the height of wheel box inner fluid.Continued to add in wheel box from wheel box top oil filler by purge oil by hydraulic pump, after liquid level exceeds inverted-loop tube setting height, fluid nature flows out from inverted-loop tube.Add the flow of wheel box purge oil by regulating, when can keep test run, in casing, liquid level is substantially got off on suitable height, ensures that the parts in wheel box are rinsed fully, lubricate, cool.
Accompanying drawing explanation
Fig. 1 is the structural representation of the invention;
Fig. 2 is the three-dimensional disassembly diagram of Fig. 1.
In figure: 1, O RunddichtringO first; 2, S shape pipe; 3, magnetic filter; 4, magnetic blocks up; 5, inverted-loop tube; 6, O RunddichtringO second; 7, guide pipe.
Embodiment
For innovation and creation content, the Characteristic of the invention can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As illustrated in fig. 1 and 2, a kind of oil level holding device of wheel box test run, the one end comprising S shape pipe 2 and inverted-loop tube 5, S shape pipe is inserted in oil drain hole, and the length inserted in oil drain hole is about 100mm.The S shape pipe position be inserted in oil drain hole is set with O RunddichtringO first 1, this end of S shape pipe is also provided with the spacing axle collar that restriction S shape pipe inserts the degree of depth in oil drain hole in the outside of tube wall, one end due to S shape pipe is inserted in oil drain hole, S shape pipe defines the bearing structure of semi-girder form on oil drain hole, larger pressure is produced between the upper and lower surface of the S shape pipe of suit O RunddichtringO and oil drain hole inwall, and the friction factor of O RunddichtringO and oil drain hole inwall is comparatively large, so utilize this friction force can realize the fixing of the lateral attitude of S shape pipe.So both can prevent hydraulic oil from leaking from oil drain hole, and can prevent again oil level holding device from deviating from process of the test.
The other end of S shape pipe is communicated with one end of guide pipe 7, is provided with magnetic filter 3 and magnetic stifled 4 in S shape pipe and the connectivity part of guide pipe.Magnetic filter 3 and magnetic block up 4 and are used for adsorbing the metallic impurity with fluid outflow in wheel box process of the test, carry out single filter to the transmission fluid force feed recycled in commissioning process.The other end of guide pipe slides and is fitted with an arm of inverted-loop tube, and inverted-loop tube can move up and down in guide pipe inside, is sealed by O RunddichtringO second 6.
Because this oil level holding device and wheel box form linker, the height of the inside pipe wall at inverted-loop tube top is the liquid level in wheel box, so the height by regulating the degree of depth of inverted-loop tube in guide pipe to regulate inverted-loop tube top, thus the liquid level in wheel box can be regulated easily.
The operating principle of the invention is:
In test run test, continued to add in wheel box by purge oil by hydraulic pump from wheel box top oil filler, after liquid level exceeds inverted-loop tube setting height, fluid nature flows out from inverted-loop tube.Add the flow of wheel box purge oil by regulating, when can keep test run, in casing, liquid level is substantially got off on suitable height, ensures that the parts in wheel box are rinsed fully, lubricate, cool.Magnetic filter 3 and magnetic block up 4 can adsorb in wheel box process of the test with fluid flow out metallic impurity, single filter is carried out to the transmission fluid force feed recycled in commissioning process.
Although be described the preferred embodiment of the invention by reference to the accompanying drawings above; but the invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of the invention; do not departing under the ambit that the invention aim and claim protect, can also make a lot of form, these all belong within the protection domain of the invention.
