Description

Technical Field

[0001] The invention relates to the technical field of gearbox oil marks, in particular to a flexible oil mark device applied to a rail vehicle gearbox. Background Art

[0002] In order to improve the transmission efficiency of rail vehicles, a gearbox is usually installed inside. In order to ensure the transmission efficiency inside the gearbox, the amount of lubricating oil in the gearbox needs to be strictly controlled. In order to facilitate the observation of the amount of lubricating oil inside the gearbox, the gearbox of rail vehicles is usually equipped with an oil mark device.

[0003] Traditional oil gauges are mainly divided into window type and screw plug type. The window type usually fastens the observation window and other related parts in the gearbox housing through multiple bolts, which is troublesome to install and disassemble, and it is easy to crush the observation window; while the screw plug type oil gauge has a relatively simple internal structure, but the sealing of the parts is poor, and it is easy to seep oil, causing the window to be turbid, which is not conducive to observing the amount of lubricating oil; and both have the problem of limited observation range and observation accuracy. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the traditional oil mark device has low safety and limited observation range and observation accuracy.

[0010] An embedded LED lamp controlled by a top side adjusting wheel set is fixedly mounted on the inner wall of the inner side mounting groove corresponding to the position of the observation window.

[0011] External meshing tooth heads matching with the meshing holes are staggered and fixed on the outer arc surfaces of the upper electrically controlled driving wheel and the lower driven wheel.

[0012] A level gauge for monitoring the horizontality of the gear box body is fixedly mounted on the outer side of the gear box body.

[0013] A scale for conveniently recording the remaining amount of gear oil is provided on the outer side of the flexible ruler.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Figure 1 , Figure 2 , Figure 3 and Figure 4 A flexible oil mark device applied to a rail vehicle gearbox is shown, comprising a gearbox body 1, a lateral cover shell 2 is fixedly mounted on the outer opening of the gearbox body 1, an inner assembly groove 3 is provided on the inner wall of the lateral cover shell 2, a flexible ruler 4 is slidably mounted inside the inner assembly groove 3, a top side adjusting wheel group 5 for controlling the sliding of the flexible ruler 4 is movably mounted on the top of the inner assembly groove 3, an observation window 6 is arranged on the lateral cover shell 2 at a position corresponding to the flexible ruler 4, meshing holes 7 matching with the top side adjusting wheel group 5 are provided on both sides of the flexible ruler 4, and a magnetically controlled lateral scraper plate 8 controlled by the top side adjusting wheel group 5 is elastically mounted on the inner top surface of the inner assembly groove 3.

[0024] Working principle: When people need to measure the amount of oil, they press the switch located on the side wall of the lateral cover 2. The switch has an electric control automatic reset energy supply. Press to start and release to reset. There are two sets of control mechanisms installed in different positions, one is set on the inside and started by pressing, and the other is set at the opening and started by releasing, thereby controlling the top side adjusting wheel group 5 to start, and then the top side adjusting wheel group 5 drives the flexible ruler 4 to slide and adjust inside the inner assembly groove 3. The flexible ruler 4 drives the oil at the bottom upward, and the excess oil on the surface is scraped off by the magnetically controlled side scraper plate 8. People judge the oil level according to the amount of oil in the meshing hole 7. After the observation, people release the pressed switch, and then the top side adjusting wheel group 5 automatically resets to the initial position through the reset switch.

[0025] For assembly purposes, an arc-shaped assembly groove 9 for mounting the top-side adjusting wheel set 5 is provided on the inner assembly groove 3 .

[0026] The arc-shaped assembly groove 9 on the lower side and the gear box body 1 are provided with oil drain ports to facilitate the return of the oil at the top.

[0027] In order to coordinate the guiding and driving, the top side adjusting wheel set 5 comprises an upper electrically controlled driving wheel 51 installed in the arc-shaped assembly groove on the upper side and a lower driven wheel 52 installed in the arc-shaped assembly groove on the lower side.

[0028] The upper electrically controlled driving wheel 51 is composed of an embedded driving motor installed on the inner side of the arc-shaped assembly groove on the upper side and a driving wheel axially fixed on the output shaft of the embedded driving motor. The embedded driving motor drives the driving wheel to control the flexible ruler 4 to perform sliding adjustment.

[0029] In order to cooperate with magnetic control, the magnetically controlled side scraper plate 8 includes a first elastic scraper plate 81 installed on one side of the inner top surface of the inner assembly groove 3, a second elastic scraper plate 82 installed on the other side of the inner top surface of the inner assembly groove 3, a first embedded electromagnet 83 fixed on one side of the inner top surface of the inner assembly groove 3, and a second embedded electromagnet 84 fixed on the other side of the inner top surface of the inner assembly groove 3.

[0030] The first embedded electromagnet 83 is activated to control the flipping adjustment of the first elastic scraper plate 81 ; the second embedded electromagnet 84 is activated to control the flipping adjustment of the second elastic scraper plate 82 .

[0031] When the top side adjusting wheel group 5 drives the flexible ruler 4 to slide toward the first elastic scraper plate 81, the first embedded electromagnet 83 will be activated to control the first elastic scraper plate 81 to separate from the surface of the flexible ruler 4; when the top side adjusting wheel group 5 drives the flexible ruler 4 to slide toward the second elastic scraper plate 82, the second embedded electromagnet 84 will be activated to control the second elastic scraper plate 82 to separate from the surface of the flexible ruler 4.

[0032] It is shown that the first elastic scraper plate 81 and the second elastic scraper plate 82 are close to the surface of the flexible ruler 4 when idle.

[0033] In order to reduce the cost of later use, an oil scraper plate 85 is sleeved and fixed on the outer side of the first elastic scraper plate 81 and the second elastic scraper plate 82 .

[0034] In order to facilitate observation, an embedded LED lamp 10 controlled by a top-side adjusting wheel set 5 is fixedly mounted on the inner wall of the inner mounting groove 3 corresponding to the position of the observation window 6 .

[0035] When the top-side adjusting wheel set 5 is started, the embedded LED lamp 10 will be started in conjunction, thereby improving the internal illumination and making it easier for people to observe in low-light conditions.

[0036] In order to avoid slipping and facilitate the discharge of oil from the meshing hole 7, external meshing tooth heads 11 matching the meshing hole 7 are staggered and fixed on the outer arc surfaces of the upper electrically controlled driving wheel 51 and the lower driven wheel 52.

[0037] In order to facilitate people to more accurately calculate the internal oil volume, a level meter 12 for monitoring the horizontality of the gear box body 1 is fixedly installed on the outer surface of the gear box body 1.

[0038] People first read the value on the flexible ruler 4, and then increase or decrease the oil volume value by the inclination angle of the level 12. When the flexible ruler 4 is at a low position, the relative coefficient is increased to obtain a relatively accurate oil volume. The coefficient value is engraved on the surface of the level 12 for easy operation.

[0039] In order to visually display the oil volume, a scale 13 for conveniently recording the remaining amount of gear oil is provided on the outer side of the flexible ruler 4.

[0040] When the flexible ruler 4 is attached to the inner wall of the inner assembly groove 3 and slides upward, the oil inside will stick to the surface and the inside of the meshing hole 7. When passing through the magnetically controlled lateral scraper 8, the scraper plate 85 at its outer end will scrape off the oil stuck to the outer surface of the flexible rack 4. Since the fluidity of the oil inside the meshing hole 7 is relatively poor, a part of it will remain inside the meshing hole 7. People can obtain the height of the real oil level inside the meshing hole 7 by the amount of oil inside the meshing hole 7.

[0041] The scale is set to directly mark the number of remaining oil.

[0042] In order to improve the sealing and shock absorption properties on the assembly surface, the assembly surfaces of the gear box body 1 and the lateral cover shell 2 are both provided with staggered sealing rubber rings 14 .

[0043] The sealing rubber rings 14 on the assembly surfaces of the gear housing 1 and the lateral cover 2 are arranged in a staggered manner.

[0044] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
