Description

Technical Field

[0001] The present application relates to the technical field of dynamometers, and in particular to a servo motor drag torque dynamometer. Background Art

[0002] Dynamometer, also known as dynamometer, is mainly used to test the power of the engine. It can also be used as a loading device for gearboxes, reducers and transmissions to test their transmission power. The electric dynamometer uses a motor to measure the torque output on various power mechanical shafts, and combines the speed to determine the power. The most commonly used ones are DC dynamometers, AC dynamometers and eddy current dynamometers.

[0003] According to the announcement number: CN216246938U, a torque dynamometer test equipment is disclosed. This technology discloses "including a first bottom load-bearing plate, a first slide rail is fixedly installed inside the first bottom load-bearing plate, a slider is slidably connected to the inner surface of the first slide rail, and the right side of the first bottom load-bearing plate is movably connected to the second bottom load-bearing plate through a hinge plate, etc., which has the technical effects of taking out the movable hook on the movable connection bar from the fixed sleeve block, lowering the second bottom load-bearing plate, connecting the first slide rail and the second slide rail together, and then pulling out the slider, controlling the two hydraulic telescopic rods to drive the entire placement platform to rise to the required height through the support plate, so that the power machinery that needs to detect torque can be placed at an appropriate height, just connected to the input shaft of the dynamometer, making the entire equipment easy to store and freely adjust the placement platform height, etc.";

[0004] With respect to the above-mentioned related technologies, the inventors believe that when the torque dynamometers in the prior art perform torque dynamometers on motors, most of the torque dynamometers cannot connect and transmit the test motors well, which causes the torque dynamometers to become loose easily during torque dynamometer measurement, thereby causing the dynamometer measurement results of the torque dynamometer to easily deviate. Moreover, when the torque dynamometers in the prior art perform torque dynamometers on motors, most of the torque dynamometers cannot adjust the test motors well, resulting in the torque dynamometers being able to install test motors of certain sizes only, thereby causing the torque dynamometers to have poor applicability.
