Description

Technical Field

[0001] This utility model belongs to the field of gear wear detection technology, specifically relating to a tool for detecting wear on motor shaft gears. Background Technology

[0002] The principle of ferrospectroscopy for detecting gear wear is based on ferrospectroscopy techniques in tribology. During gear operation, friction and wear occur between the tooth surfaces, generating various wear particles. These particles are distributed in the lubricating oil as it circulates. The ferrospectrometer introduces an oil sample containing these wear particles into an analytical region with a high-intensity magnetic field. Utilizing the attraction of the magnetic field to the ferromagnetic particles, the particles are deposited in an orderly manner on a specially designed substrate according to their size and magnetic properties. By observing, analyzing, and measuring the wear particles deposited on the substrate, information about gear wear can be obtained, such as the number, size, shape, and composition of the wear particles, thereby assessing the wear condition and degree of the gear.

[0003] However, existing ferrography instruments can only detect a small amount of lubricating oil at a time during the detection process, and cannot distinguish and detect multiple different lubricating oils, thus reducing their practicality. In addition, the space for placing the lubricating oil container is limited, and when there are many samples to be tested, the lubricating oil container needs to be replaced frequently. Utility Model Content

[0004] The purpose of this invention is to provide a tool for detecting wear on motor shaft gears, which can connect to multiple lubricating oil containers simultaneously and expand the container placement area to facilitate the testing of different types of lubricating oil, thereby improving its practicality.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A tool for detecting wear on motor shaft gears includes a ferrometer body. A placement groove is provided on the side of the ferrometer body, and a drain pipe is mounted on the top surface of the placement groove. Several connectors are fixedly connected to the side wall of the drain pipe, and valves are installed at the connections between the side wall of the drain pipe and the connectors. A storage groove is provided on the side of the ferrometer body below the placement groove, and a movable plate is slidably connected within the storage groove. Positioning components are provided on the front and rear side walls of the movable plate, and a support component is provided on the top surface of the movable plate near the right side. At least two rubber pads are fixedly connected to the top surface of the movable plate.

[0007] The positioning component includes grooves formed on the front and rear side walls of the movable plate. A spring is fixedly connected to the side wall of the groove, and a plug rod is fixedly connected to the other end of the spring. Several insertion holes are formed on the front and rear side walls of the storage slot. The plug rod is adapted to the insertion holes, and a reset component is provided on the side wall of the plug rod.

[0008] The reset assembly includes a pull rope. The side wall of the movable plate has a through hole, and the pull rope is located in the through hole. Both the through hole and the pull rope are T-shaped. Both ends of the pull rope are fixedly connected to the two side rods, and the other end of the pull rope passes through the through hole and is fixedly connected to a pull ring.

[0009] The sidewall of the through hole is rotatably connected to a roller at the corner, and the pull rope abuts against the roller.

[0010] The support assembly includes two screw holes on the top surface of the movable plate near the right side. A screw rod is threaded into the screw holes, a washer is rotatably connected to the bottom end of the screw rod, and a rotating plate is fixedly connected to the top end of the screw rod.

[0011] Two tie rods are fixedly connected to the right side wall of the movable plate.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a motor shaft gear wear detection tool. Through the cooperation of the ferrography instrument body, the movable plate, the positioning component, etc., multiple lubricating oil containers can be placed according to the testing requirements of lubricating oil.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-6 As shown, a tool for detecting wear of motor shaft gears includes a ferrometer body 1. A placement groove 2 is provided on the side of the ferrometer body 1. A drain pipe 3 is mounted on the top surface of the placement groove 2. Several connectors 4 are fixedly connected to the side wall of the drain pipe 3. Valves 5 are installed at the connection points between the side wall of the drain pipe 3 and the connectors 4. When multiple lubricating oil containers are connected through the connectors 4, the connection status between a single lubricating oil container and the drain pipe 3 can be controlled by the valves 5, which facilitates the introduction of lubricating oil into the ferrometer for measurement. A storage groove 6 is provided on the side of the ferrometer body 1 below the placement groove 2. A movable plate 7 is slidably connected in the storage groove 6. Positioning components are provided on the front and rear side walls of the movable plate 7. A support component is provided on the top surface of the movable plate 7 near the right side. At least two rubber pads 20 are fixedly connected to the top surface of the movable plate 7.

[0024] The principle of ferrography is to use magnetic force to separate metal particles from oil and arrange them on a substrate according to their size. The basic principle and method of ferrography technology is to separate wear debris and fragments mixed in lubricating oil (or hydraulic oil) and precipitate them sequentially and non-overlappingly onto a transparent substrate for observation under a microscope for qualitative analysis. Using a densitometer mounted on the ferrographic microscope, the relative content of different sizes of wear particles on the substrate can also be quantitatively analyzed. Computer image processing of the wear debris can also be used to obtain relevant parameters; the measurements include the size of the wear particle concentration, the morphology of the wear particles, and the composition of the wear particles. Furthermore, the principle of ferrography and its docking operation with the container are based on existing mature technology and will not be detailed in this scheme.

[0025] like Figure 3 and Figure 6As shown, the positioning component includes grooves 8 formed on the front and rear side walls of the movable plate 7. A spring 9 is fixedly connected to the side wall of the groove 8, and a rod 10 is fixedly connected to the other end of the spring 9. Several insertion holes 14 are respectively formed on the front and rear side walls of the storage slot 6. The rod 10 is adapted to the insertion holes 14, and a reset component is provided on the side wall of the rod 10. By setting the positioning component, the extension or retraction of the movable plate 7 can be controlled, which facilitates the increase of the placement area for the lubricating oil container and allows for continuous testing of multiple bottles of lubricating oil at the same time.

[0026] In addition, to ensure the accuracy of gear wear detection in lubricating oil, after a single bottle of lubricating oil has been tested, cleaning fluid can be injected into the ferrometer through control valve 5 to flush away the oil residue from the previous test, thereby improving the accuracy of the test data and avoiding confusion caused by residues from different grades of lubricating oil.

[0027] like Figure 2 and Figure 3 As shown, the reset assembly includes a pull rope 11. A through hole is provided on the side wall of the movable plate 7, and the pull rope 11 is located within the through hole. Both the through hole and the pull rope 11 are T-shaped. Both ends of the pull rope 11 are fixedly connected to the two side insert rods 10, and the other end of the pull rope 11 passes through the through hole and is fixedly connected to a pull ring 12. The reset assembly can control the telescopic movement of the positioning assembly, facilitating the positioning of the movable plate 7 and allowing it to extend to a suitable position.

[0028] like Figure 3 As shown, a roller 13 is rotatably connected to the sidewall of the through hole at the corner, and the pull rope 11 abuts against the roller 13. The roller 13 can guide the pull rope 11, while reducing the friction of the pull rope 11 and improving its service life.

[0029] like Figure 2 and Figure 5 As shown, the support assembly includes two screw holes 16 on the top surface of the movable plate 7 near the right side. A screw 17 is threaded into the screw holes 16. A washer 18 is rotatably connected to the bottom end of the screw 17. A rotating plate 19 is fixedly connected to the top end of the screw 17.

[0030] In order to further increase the stability of the movable plate 7, the pad 18 can be lowered by rotating the screw 17 to support the movable plate 7. The pad 18 is made of rubber, which can increase the friction with the table.

[0031] Two tie rods 15 are fixedly connected to the right side wall of the movable plate 7. This facilitates the force applied to the movable plate 7, allowing it to be easily pulled out.

[0032] The working principle of this utility model is as follows: First, the lubricating oil inside the gearbox of the gear to be tested is drained into a container. Then, the container is placed in the placement groove 2 and connected to the connector 4 through a pipe. When there is a lot of lubricating oil in the container, the pull ring 12 can be pulled to tighten the pull rope 11. The pull rope 11 drives the insertion rod 10 to move into the groove 8. At the same time, the spring 9 is compressed to release the fixation of the movable plate 7. Then, after the movable plate 7 is pulled out to the appropriate position, the pull ring 12 is released. The spring 9 rebounds and drives the insertion rod 10 to insert into the corresponding insertion hole 14, completing the adjustment of the movable plate 7. Then, the rotating plate 19 is rotated to drive the screw 17 to rotate. The screw 17 drives the washer 18 to move downward to facilitate contact with the table and support the movable plate 7, thereby increasing the stability when the container is placed.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
