Description

Technical Field

[0001] This utility model relates to the field of gearbox testing technology, and in particular to a test bench for the gearbox of an electric boat outboard motor. Background Technology

[0002] In the field of new energy ships, the outboard motor of electric ships is the core power unit of small and medium-sized ships. The reliability of its gearbox directly determines the navigation safety and power transmission efficiency. The gearbox must withstand the reverse torque of the propeller, the corrosion risk caused by seawater splash, and the impact load during start-up and shutdown. Therefore, before leaving the factory, it is necessary to simulate actual working conditions through a dedicated test bench to test its lubrication performance, load-bearing capacity, vibration and noise and other key indicators to ensure compliance with standards. However, the existing test bench still has the following problems: Traditional gearbox test benches mainly focus on testing mechanical transmission performance, often neglecting the real-time monitoring of the impact of lubricating oil condition on gearbox operation. In actual testing, gearbox wear will generate metal shavings, leading to lubricating oil contamination and deterioration. Existing equipment lacks online oil monitoring function, usually requiring shutdown for sampling and testing, which is not only inefficient but also fails to reflect real-time changes in oil condition during the testing process. Traditional open-circuit oil systems cannot achieve lubricating oil circulation and filtration. Unfiltered lubricating oil may contain metal debris, and repeated use will lead to secondary wear, further affecting the accuracy and reliability of the test. Therefore, an experimental platform for the outboard gearbox of an electric boat is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing gearbox test benches, such as the lack of intuitive oil detection functions and the lack of a circulating filtration system for lubricating oil, and to propose an electric ship outboard motor gearbox test bench.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The test bench for the gearbox of an electric boat outboard motor includes a test bench, which consists of a workbench, a support plate, and four support legs. The workbench and the support plate are fixedly connected to the top and bottom of the four support legs, respectively. The filter tank, colorimetric box, and two oil pumps are all fixedly connected to the top of the support plate; The filter tank includes an oil reservoir, a filter element housing, and a filter screen. The filter screen is detachably inserted into the inside of the filter element housing, which is inserted into one side of the oil reservoir and fixed with bolts. The lubricating oil flows from the outlet of the filter oil tank through a pipeline to one of the oil pumps, the gearbox, the colorimetric box, and another oil pump, and finally flows back from the outlet of the other oil pump to the inlet of the filter oil tank.

[0005] In one possible design, the colorimetric box includes a detection housing, a colorimetric scale, and a transparent oil box. The colorimetric scale is fixedly connected to the inside of the detection housing, and the transparent oil box is inserted into one side of the colorimetric scale and fixedly connected by bolts.

[0006] In one possible design, the top of the workbench is fixedly connected to two supports, the top of the two supports is fixedly connected to the same support plate, and the top of the support plate is fixedly connected to the power box II.

[0007] In one possible design, two linear guides are fixedly connected to the top of the workbench and one side of the two supports. A loading plate is slidably connected to the top of the two linear guides located on the top of the workbench, and a lifting platform is slidably connected to one side of the two linear guides located on one side of the two supports.

[0008] In one possible design, a lead screw is rotatably connected between the support plate and the worktable. A motor I is fixedly connected to the upper part of the power box II. One end of the output shaft of motor I is fixed to the lead screw. A sleeve is fixedly connected to one side of the lifting platform. The sleeve is threaded to the outer circumference of the lead screw.

[0009] In one possible design, a power box I is fixedly connected to one side of the lifting platform, and a motor II is fixedly connected inside the power box I. One end of the output shaft of the motor II is fixed to the input end of the gearbox.

[0010] In one possible design, side plates are fixedly connected to the upper sides of both sides of the loading plate, and adjusting screws are threaded to the middle of the two side plates. One end of each adjusting screw is rotatably connected to a clamping plate, and the bottom of the clamping plate is in contact with the top of the loading plate.

[0011] In one possible design, a sound level meter is fixedly connected to the top side of the workbench.

[0012] In this application: The test bench has two linear guide rails on the top of the workbench. The loading plate is slidably connected to the upper part of the rails. The operator can push the loading plate along the linear guide rails to adjust its lateral position, so that the gearbox to be tested can be placed stably in the center of the loading plate. The side plates on both sides of the loading plate are threaded with adjusting screws. When the adjusting screws are rotated, the clamping plate at the end can move towards the gearbox. The bottom of the clamping plate is in contact with the top of the loading plate to ensure that it remains horizontal during the movement and avoids clamping deviation. The operator can control the clamping force by adjusting the screw depth to adapt to gearboxes of different widths. Rubber pads can be attached to the inside of the clamping plate to avoid scratching the gearbox shell by rigid contact. Finally, the gearbox is clamped in both directions evenly. Two supports on the top of the workbench support the support plate. A lead screw is rotatably connected between the support plate and the workbench. The output shaft of motor I inside power box II is fixed to the lead screw. When motor I is started, the lead screw can be driven to rotate (speed). The lifting platform is slidably connected to the linear guide rail on one side of the support, and the sleeve fixed on one side of it is threaded with the lead screw. When the lead screw rotates, the sleeve drives the lifting platform to slide up and down along the linear guide rail, thereby adjusting the height of power box I on one side of the lifting platform. After motor II starts, its output shaft is directly and fixedly connected to the input end of the gearbox, and can output different torques and speeds according to experimental requirements; Two oil pumps on the top of the support plate provide power for the lubrication circulation. One of the oil pumps is connected to the oil outlet of the filter oil tank and the oil inlet of the gearbox through a pipeline. After starting, it pumps the filtered lubricating oil into the gearbox to lubricate the gear meshing parts, bearings and other key components, and removes the heat generated during operation. The other oil pump is connected to the oil outlet of the gearbox and the colorimetric box. It pumps the lubricating oil that has passed through the gearbox to the colorimetric box to complete the circulation power transmission. The lubricating oil that flows back to the filter oil tank first enters the filter element housing and filters metal debris and other materials through the filter screen inserted on the inner side. After the lubricating oil is delivered to the colorimetric box by the second oil pump, it enters the transparent oil box. The colorimetric scale fixed inside the colorimetric box marks different standard color levels. The transparent oil box is in close contact with the colorimetric scale, and the operator can directly observe the color of the lubricating oil in the transparent oil box and compare it with the colorimetric scale. This allows for real-time monitoring of oil changes and the detection of early wear signals. The sound level meter on one side of the top of the workbench can collect the noise level of the gearbox in real time.

[0013] Beneficial effects: In this utility model, the electric boat outboard gearbox test bench, through the coordinated use of components such as filter oil tank, oil storage tank, filter element housing, and filter screen, realizes real-time filtration of lubricating oil during the test. The filter screen can effectively remove impurities in the lubricating oil, avoiding secondary pollution of the lubricating oil by impurities and affecting the test results. In this utility model, the electric boat outboard gearbox test bench, through the combined use of components such as a colorimetric box, a test housing, a colorimetric scale, and a transparent oil box, enables operators to intuitively observe the color change of the lubricating oil, and promptly judge the oil quality and gearbox operating status, thereby significantly improving the scientificity and reliability of the testing process. In this invention, by integrating components such as a filter oil tank and a colorimetric box, a closed-loop oil circuit system is constructed, which realizes real-time filtration and status monitoring of lubricating oil during the testing process, thereby significantly improving the scientificity and reliability of the testing process.
