[0002] In modern agricultural production, the efficient operation of agricultural machinery is of great significance for improving agricultural productivity and ensuring food security. As one of the core components of agricultural machinery, the performance and reliability of the transmission system directly determine the overall performance of the machinery. Therefore, the break-in process is a crucial step in ensuring product quality during the production of agricultural machinery transmission systems.

[0049] Working principle:

[0050] When using the intelligent break-in bench of this agricultural machinery transmission system, firstly, the axle to be tested is hoisted onto the support plate 301 of the break-in fixture 3 by a crane, and the axle is fixed by the clamps 309.

[0051] The axle lifting support is equipped with a third slide rail 304 and a third slider 305, which can move in parallel. The height can be adjusted by adjusting the screw 307 to adapt to different axle models.

[0052] The input motor 208 of the main power component 2 is connected to the power input end of the axle through the spline 209 to provide power to the axle. A speed and torque detection device 210 is installed between the input motor 208 and the power shaft to detect the torque and speed during input.

[0053] The sliding table 204 of the main power component 2 is driven by the first drive motor 211 driving the first gear 212 and the first rack plate 213 to mesh and transmit power.

[0054] When the axle to be tested is placed in the test position, the first drive motor 211, in conjunction with the first gear 212 and the first rack plate 213, drives the sliding table 204 of the main power assembly 2 to move to the docking position. The upper part of the main power assembly 2 is driven by the first push cylinder 214. The first push cylinder 214 extends and pushes the power shaft to contact the axle input shaft. At the same time, the input motor 208 rotates slowly until the splines 209 on both sides are successfully docked.

[0055] The structure of the left loading component 4 and the right loading component 5 is consistent with the principle of the main power component 2. The left loading component 4 and the right loading component 5 are additionally equipped with a rocker arm 415, which, together with the lead screw 412, sprocket 413 and chain 414, realizes the up and down movement of the upper lifting plate 410 of the left loading component 4 and the right loading component 5, so as to realize the docking of different models of axles.

[0056] During the break-in process, the main power component 2 drives the axle to rotate, and the input speed and torque are recorded by the speed and torque detection device 210; the left loading component 4 and the right loading component 5 on both sides automatically connect to the output end of the axle, and the loading device 423 follows the axle to record the torque and speed of each gear;

[0057] When the loading device 423 loads the axle, the axle half shaft is equivalent to the input end, while the main power component 2 is equivalent to the load, thereby realizing the detection of the axle.

[0058] Preferably, the equipment is used in conjunction with an automatic control device, which enables the equipment to output data such as torque, speed, gear, and noise in real time during the break-in process, as well as torque curves and tables; after the test is completed, the equipment automatically stops, the clamps of the break-in fixture 3 open, and the worker lifts the axle away from the equipment.
