Background technique
Worm-gear speed reducer is a kind of power transmission mechanism, using the velocity transducer of gear, by motor (motor)
Winding number decelerates to desired winding number, and obtains the mechanism of larger torque.In the mechanism currently used for transmitting power and movement
In, the application range of speed reducer is quite extensive.
The basic structure of worm-gear speed reducer is mainly driving parts worm and gear, axis, bearing, cabinet and its attachment.
Worm-gear speed reducer can be divided into three big basic structure portions: cabinet, worm and gear, bearing are combined with axis.Cabinet is worm and gear
The pedestal of all accessories in speed reducer is supporting and fixing shaft components, guarantees the correct relative position of transmission accessory and supporting role
The important accessory of load on speed reducer.The main function of worm and gear is movement and the power transmitted between two alternating axis,
The main function of bearing and axis is power transmitting, operates and improve efficiency.
Worm-gear speed reducer can have abrasion such as worm gear abrasion, helical teeth foot wheel abrasion or bearing damage when in use, need
The good contact between part is kept injecting a certain amount of lubricating oil in cabinet, guarantees the workability of worm-gear speed reducer
Can, prolong the service life.
But since the air-leakage test of the cabinet of worm-gear speed reducer is relatively difficult to carry out, general air-leakage test side
Method has bowssening, differential pressure method, helium inspection method and supercritical ultrasonics technology.But these detection methods are not all suitable for the air-tightness inspection of cabinet
It surveys.Followed by oiling entrance is smaller (diameter 10mm or so), injection flow deficiency is easy to produce if artificial oiling, or overflow.
Summary of the invention
For the deficiency of background technique, the purpose of this utility model is to provide a kind of worm-gear speed reducer cabinet is airtight
Property detection and quantification oiling device.
The utility model includes transmission device, gas source, shut-off valve, pneumatic filter, pressure reducing valve, check valve, air pressure sensing
Device, sealing device, filling valve, oil pump, oil filter, temporary storage box, linear stepping motor, metering pump, control cabinet, alarm,
Shell, pedestal and locator.
The gas source is sequentially connected shut-off valve, pneumatic filter, pressure reducing valve, the first check valve and air pressure sensing by pipeline
Then device passes through the fixed sealing device on the shell of cage connection from internal.
It is unidirectional that the oil pump by pipeline is sequentially connected oil filter, temporary storage box, second one-way valve, metering pump and third
Then valve passes through the fixed filling valve on the shell of cage connection from internal, the metering pump is driven by linear stepping motor.
The transmission device is placed in the two sides of pedestal and is aligned the conveyer belt on pedestal, and locator is mounted on pedestal edge
Edge, there are two the locators, the first station and second station is corresponded respectively in transmission tape motion direction, wherein first
Station is air-leakage test station, and top is equipped with sealing device moving up and down, and second station is oiling station, and top is equipped with
Filling valve moving up and down, control cabinet and alarm are mounted on the left side of shell.
The utility model has the beneficial effects that the utility model carrys out detection case by using baroceptor and controller analysis
The air-tightness of body, avoiding bowssening can be to complexity, the high cost of helium inspection method etc. for the corrosion, differential pressure method that part generates.It is lower
Cost and simple testing principle, portable operation, improve to a certain extent the detection of worm-gear speed reducer cabinet with
And the efficiency of oiling.
Detailed description of the invention
Fig. 1 is the positive schematic three dimensional views of the utility model；
Fig. 2 is the internal structure chart of the utility model；
Fig. 3 is filling valve and schematic diagram of sealing device equipped with guide rail.
Specific embodiment
As shown in Figure 1 to Figure 3, a kind of worm-gear speed reducer cabinet air-leakage test and quantification oiling device, including pass
Send device 1-1,1-2, gas source, cut-off 2, pneumatic filter 3, pressure reducing valve 4, check valve 5-1,5-2,5-2, baroceptor 6, close
Seal apparatus 7, oil filter 8, temporary storage box 9, linear stepping motor 10, metering pump 11, filling valve 12, electric cabinet 13, alarm
14, shell 15, pedestal 16 and locator 17.
The gas source is sequentially connected shut-off valve 2, pneumatic filter 3, pressure reducing valve 4, check valve 5-1, air pressure transmission by pipeline
Then sensor 6 passes through cage connection from inside and is fixed on the sealing device 7 on shell 15.
The oil pump is sequentially connected oil filter 8, temporary storage box 9, check valve 5-3, metering pump 11, check valve by pipeline
Then 5-2 passes through cage connection from inside and is fixed on the filling valve 7 on shell 15.
The conveyer belt that described transmission device 1-1, the 1-2 is placed in the two sides of pedestal 16 and is aligned on pedestal 16, locator
17-1,17-2 are mounted on base edge, and control cabinet 13 and alarm 14 are mounted on the left side of shell, the sealing device with it is filling
