Description

Technical Field

[0001] The utility model relates to the technical field of speed reducer test devices, in particular to a speed reducer drag test device. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery. At the same time, reducers are generally used for low-speed and high-torque transmission equipment. The power of an electric motor, internal combustion engine or other high-speed operation is decelerated by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio.

[0003] Before the reducer is used, it is usually necessary to conduct a towing test on the reducer. The main reason is to verify its performance and ensure its stability and reliability in actual applications. Specifically, the towing test can detect the key parameters of the reducer such as speed, torque, efficiency, etc. to verify whether it meets the design requirements. The towing test is an effective testing method. By simulating the actual working environment and load conditions of the reducer, the performance of the reducer can be comprehensively evaluated.

[0004] At present, when conducting a reducer drag test, it is usually necessary to first install the reducer on the test bench, and ensure that the installation is correct and the connecting parts are securely fastened, and then conduct a no-load test and load the sample on the reducer, so as to record the test data and analyze it based on the data.

[0005] When conducting a drag test on a reducer, bolts are usually used to fix the position of the reducer. However, when testing multiple reducers, the bolts need to be repeatedly turned to fix and disassemble the position of the reducer. This operation is more troublesome and can easily reduce the work efficiency of the reducer case. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a reducer towing test device to solve the technical problem that when testing multiple reducers, it is necessary to repeatedly turn the bolts to fix and disassemble the position of the reducer, which is troublesome to operate and easily reduces the work efficiency of the reducer case.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reducer towing test device, comprising an operating table, a fixed block is fixedly connected to the top of the operating table, a connecting plate is movably connected to one side of the fixed block, a groove is provided on the top of the connecting plate, a group of rotating shafts are rotatably connected in the groove, a connecting piece is movably penetrated through the outer surface of each rotating shaft, and the connecting piece is arranged in an "L"-shaped structure, the rotating shaft and the corresponding connecting piece are connected by a coil spring, a plurality of plug rods are fixedly connected to one side of the connecting piece, a base is movably connected in the groove, a reducer body is provided on the top of the base, a plurality of groups of jacks are provided on the top of the base, and the plug rods are movable in the jacks.

[0012] By adopting the above technical solution, one of the lead screws is driven to rotate by the motor, so that the other lead screw can be rotated synchronously through the gears and the gears, so that the connecting plate can move up and down on the outer surface of the lead screw, which is beneficial when installing the reducer body. The output end of the reducer can be connected to the movable tube first, and then the connecting plate is driven to move upward by the rotation of the lead screw until the groove in the connecting plate is connected to the base. The plug rod can be inserted into the socket to complete the installation of the reducer body.

[0013] The utility model is further configured that a movable plate is movably connected in the groove, and the movable plate and the groove are connected via a spring.

At this time, the insertion rod on the other side of the connecting piece is inserted into the insertion hole of the base, so that the position of the base and the reducer body can be fixed, and when the reducer body is subjected to a towing test, the screw rod does not drive the connecting plate to move downward, so that the position of the base and the reducer body can be always fixed, which is convenient for better towing test of the reducer body. This structure is conducive to quickly completing the installation of the reducer body, and is convenient for improving the work efficiency of installing the reducer body.
