Indicating liquid liquid level in pipe declines situation, if the liquid level in second hose does not decline or slowly declines, described in explanation
There is no leakage problems to illustrate the worm speed-down case if the liquid level rapid decrease in second hose for worm speed-down case
There are leakage problems.
To sum up, it using method as above, is on the one hand not necessarily to carry out standing observation, can be quick, it is intuitive to detect gas leakage feelings
Condition and leakage part, need to empty lubricating oil again in another aspect traditional detection mode and weigh again for the retarder leaked
New assembling, causes the waste of lubricating oil, existing detection mode then not to waste lubricating oil, reduce use cost.
Description of the drawings
Below in conjunction with attached drawing, invention is further explained：
Fig. 1 is schematic diagram when detection device is detected worm speed-down case in the present invention；
Wherein：100- shells, 200- windows, 300- oil outlets, 401- adapter rings, 402- rubber stoppers, 403- pressurization balloons,
The first hoses of 404-, the second hoses of 405-, 406- scale plates, 407- indicating liquids, 408- liquid levels.
Specific implementation mode
The present invention is further elaborated below by way of specific implementation mode：
Fig. 1 illustrates schematic diagram when detection device is detected worm speed-down case, and there are one worm speed-down case tools
Shell 100, shell 100 is interior to be equipped with train of reduction gears, and shell 100 is equipped with 200 He of window for lubricating oil is added and is observed
Oil outlet 300 for lubricating oil to be discharged, the component of the detection device include for seal the plug of oil outlet 300 with mounted on regarding
Adapter ring 401 on hole 200 and rubber stopper 402, adapter ring 401 are rubber material, and the lower face of adapter ring 401 is ladder-like comprising
With more than the second cylinder portion of 200 internal diameter of window, adapter ring 401 is mounted in the first cylinder portion consistent with 200 internal diameter of window
The inner face cooperation of the outer end face Yu window 200 in the first cylinder portion, the lower face in the second cylinder portion and window when on axis hole
200 upper surface cooperation, wherein rubber washer is additionally provided between the second cylinder portion and window 200, to obtain outstanding sealing
Effect.
Installing port up and down is equipped at 401 center of adapter ring, rubber stopper 402 is set in the installing port, rubber stopper 402
The inner face of side wall and installing port is fitted close to prevent gas leakage.
The first hose 404 and the second hose 405 are drawn on rubber stopper 402 respectively, wherein the first hose 404 and pressurization balloon
403 connections, the second hose 405 are fixed on scale plate 406 and are marked with indicating liquid 407 in pipe, and indicating liquid 407 can be
By the water of staining reagent, alcohol, kerosene etc., the second hose 405 is fixed on as follows on scale plate 406：This second
Hose 405 includes its double-end two ends section of a coiled coil Duan Yucong, which is fixed on vertical pendulum
406 bottom of scale plate put, one of end section are vertically fixed in the form of exporting upward on scale plate 406, and scale is set
The side of end section is placed in for observing, another end section includes being perpendicularly fixed at scale plate after the extraction of coiled coil section
Pipe shaft on 406 and the outlet being connected with rubber stopper 402, the pipe shaft extend vertically up to be more than the coiled coil section always
Level height, the liquid level of indicating liquid 407 is more than the level height of coiled coil section but less than residing for rubber stopper 402
Level height, to prevent indicating liquid 407 because operation error is penetrated into worm speed-down case, using such modes of emplacement, one comes the
Two hoses 405 have longer stroke, and two also accommodate more liquid in pipe, can bear the pressure difference of bigger, and worm screw
Reduction box and extraneous pressure difference are bigger, and gas leak phenomenon just shows more notable, this measure therefore the accuracy that can improve detection, this
Outside, also the endurance of pressure difference can be improved by way of improving 407 density of indicating liquid, for example, by using mercury as instruction
Liquid 407, the second hose 405, which only needs progress U-shaped to put, at this time can meet to pressure difference endurance demand, but due to the poison of mercury
Property effect, such scheme do not pay the utmost attention to.
When being detected using detection device, the oil outlet 300 on worm speed-down case is sealed with plug, on window 200
Installing rubber stopper 402 after installation adapter ring 401 again makes to pass through the balloon 403 that pressurizes with extraneous hermetic seal in worm speed-down tank shell 100
The air-blowing into worm speed-down case, the liquid in the second hose 405 rise under pressure, and liquid level 408 is risen to certain height
Stop pressurization after degree, observes the dynamic of liquid level 408, illustrate that retarder is not let out if liquid does not decline or slowly declines
Reveal situation, illustrates that worm speed-down case has leakage if liquid level 408 is declined with fast speed, needed at this time to worm speed-down case
Leakage position is detected, and detection mode is to smear liquid soap toward at the connecting sewing of worm speed-down case, has seen whether bubble drum
Go out, is the position revealed on the worm speed-down case at bubble bulging.
Using method as above, be on the one hand not necessarily to carry out standing observation, can be quick, it is intuitive detect gas leakage situation and
Part is leaked, needs to empty lubricating oil group again again again for the retarder leaked in another aspect traditional detection mode
Dress, causes the waste of lubricating oil, existing detection mode then not to waste lubricating oil, reduce use cost.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Invention, and be not used as limitation of the invention, as long as in the spirit of the present invention, to embodiment described above
Variation, modification will all fall within the scope of claims of the present invention.
