Description

Technical Field

[0001] This utility model relates to the technical field of mining equipment testing devices, specifically a testing device for speed reducers. Background Technology

[0002] Speed ​​reducers are used in industries such as mining, metallurgy, and coal. They are generally used in low-speed, high-torque transmission equipment. They reduce the speed of electric motors, internal combustion engines, or other high-speed power sources by meshing a small gear on the input shaft with a large gear on the output shaft. They play a role in matching speeds and transmitting torque between the prime mover and the working machine or actuator, and are widely used in modern machinery.

[0003] As a mining machinery and equipment processing enterprise, in order to meet the needs of different applications, we need to process and manufacture corresponding speed reducer products, such as... Figure 1 The speed reducer shown is the type currently being manufactured. To check the manufacturing quality of a finished speed reducer, a no-load test is required before it leaves the factory. This involves continuous operation in both forward and reverse directions for 24-72 hours at rated speed to check the smoothness of operation, for any impacts or abnormal noises, and for any oil leaks. Currently, testing is mainly outsourced to external testing units, which requires transporting the finished speed reducer to the relevant testing facility. This method significantly increases manufacturing costs. Furthermore, due to the weight of the speed reducer, there are certain safety risks during transport. Therefore, to reduce manufacturing costs, minimize safety hazards during transport, and facilitate testing within the company, it is essential to provide a speed reducer testing device.

Specifically, it is a detection device for speed reducers.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a testing device for a speed reducer, comprising a fixed frame, a mounting frame, and a drive mechanism.

[0016] It should be noted that the term "comprising" or any other variation is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0017] like Figure 2As shown, this embodiment provides a testing device for a speed reducer, including a fixed frame 1, a mounting frame 2, and a drive mechanism 3. The mounting frame 2 is disposed on the top of the fixed frame 1 and is used to mount the speed reducer to be tested. The drive mechanism 3 is disposed in the fixed frame 1 and located below the mounting frame 2. The drive mechanism 3 is connected to the speed reducer to be tested and is used to provide power to the speed reducer to be tested.

[0018] In the manufacturing process of the detection device for a speed reducer described in this embodiment, the fixed frame 1 includes a front support frame 11, a rear support frame 12, and a motor frame 13. Two mounting frames 2 are provided. The front support frame 11 and the rear support frame 12 are fixedly connected to each other as an integral frame structure through the two mounting frames 2. An inclined support rod 14 is also provided between the front support frame 11 and the mounting frame 2, and between the rear support frame 12 and the mounting frame 2. The motor frame 13 is fixed to the middle of the front support frame 11 and located below the mounting frame 2. The drive mechanism 3 is installed in the motor frame 13.

[0019] Furthermore, in the detection device for a speed reducer described in this embodiment, the drive mechanism 3 includes a motor 31, a pulley 32, and a transmission belt 33. The motor 31 is mounted in the motor frame 13, the pulley 32 is mounted on the output shaft of the motor 31 and located outside the front support frame 11, and the transmission belt 33 is mounted on the pulley 32. The drive mechanism 3 is connected to the transmission wheel of the speed reducer to be tested via the transmission belt 33. In specific applications, since the motor 31 is a commonly used power device in the prior art, a variable frequency motor capable of driving the speed reducer can be selected for the motor 31.

[0020] Furthermore, the testing device for a speed reducer described in this embodiment is also equipped with an oil tank and an oil pipe. The oil tank is installed on the ground within the fixed frame 1, and the oil tank is connected to the oil circuit of the speed reducer to be tested via the oil pipe. Since the oil tank and oil pipe are commonly used devices in the prior art, they are not described in detail, as long as they meet the usage requirements.

[0021] like Figures 3 to 6 As shown, in specific applications, the testing device provided by this utility model works as follows: simply install the pre-fabricated reducer in the mounting bracket 2 on the fixed frame 1, and select a motor 31 that matches the reducer, install it on the motor frame 13, and connect it to the transmission wheel of the reducer to be tested through the transmission belt 33. At the rated speed, it can run continuously in both directions for 24-72 hours to test the smoothness of the reducer, whether there is any impact or abnormal noise, and whether there is any oil leakage in the oil circuit, thereby meeting the no-load test requirements of the reducer before leaving the factory.

[0022] Therefore, the detection device described in this utility model has a mounting bracket 2 on the fixed frame 1, which supports the reducer to be tested. The fixed frame 1 also has a drive mechanism 3, which provides power to drive the reducer to run, thus achieving continuous operation in both directions. This allows for the detection of the smoothness of the reducer's operation, as well as the presence of impacts and abnormal noises. In addition, since an oil tank and oil pipe are also provided, the oil pipe is connected to the oil circuit of the reducer to be tested, which allows for the detection of oil leakage in the reducer.

[0023] In summary, the testing device described in this utility model, through the cooperation of the mounting frame 2 and the drive mechanism 3, can meet the no-load testing requirements of the reducer before it leaves the factory. This not only reduces processing costs but also improves testing efficiency. Its overall structure is simple, easy to operate, and suitable for widespread use.
