Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bearing testing devices, specifically a bearing rotational flexibility testing device. Background Technology
[0002] In the field of bearing manufacturing and quality control, the rotational flexibility of a bearing is one of the key indicators for measuring its performance. Inflexible bearing rotation directly affects its vibration, lifespan, temperature rise, and other performance characteristics. Currently, the industry mainly relies on manual inspection to check bearing rotational flexibility. This method has many shortcomings, such as low inspection accuracy, low efficiency, and susceptibility to human factors, leading to significant errors. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a bearing rotation flexibility testing device, which solves the problem that the traditional bearing outer ring rotation flexibility test requires manual rotation, resulting in low testing accuracy and efficiency.
[0004] To achieve the above objectives, this utility model provides a bearing rotation flexibility testing device, including a base and a housing. The bottom of the housing has a receiving groove for accommodating an external bearing to be tested. A bracket is provided on the base, and an impeller and a driving component for communicating with an external driving device to drive the impeller to rotate are movably mounted on the bracket. The impeller includes a rotating disk and several blades arranged circumferentially on the rotating disk. A transmission shaft is coaxially connected to the bottom wall of the rotating disk. The transmission shaft is detachably connected to the housing. The housing is provided with a locking component for locking and fixing the outer ring of the bearing to be tested when it is placed in the receiving groove. A detection component for detecting the impeller rotation frequency and the number of rotations is provided on the bracket.
[0005] The advantages of adopting the above technical solution are as follows: The operator installs the bearing to be tested in the receiving groove and fixes the outer ring of the bearing with locking components. Then, the impeller is driven to rotate by the drive component, causing the housing to rotate synchronously through the transmission shaft, thus achieving synchronous rotation of the bearing outer ring. While the bearing outer ring rotates, the detection component detects the impeller rotation frequency and number of rotations, and judges and analyzes whether the bearing's rotational flexibility meets the standard based on the detection data. This technology allows for precise control of the bearing's rotation speed and number of rotations, thereby achieving automatic detection of bearing rotational flexibility. This not only solves the defects of traditional manual inspection and shortens the inspection cycle, but also greatly reduces the tediousness of manual inspection, lowers labor costs, and improves inspection efficiency, which is of great significance for bearing manufacturing and maintenance. In the above technology, the detection component detects the impeller rotation frequency and number of rotations and generates corresponding data which is transmitted to an external intelligent industrial control system. The external intelligent industrial control system analyzes this data and compares it with the rotational values preset by the operator to determine whether the bearing's rotational flexibility meets the standard. For example, the detection component will... The collected impeller rotation count and frequency are used to generate waveforms or curves. The intelligent industrial control system can determine whether there are blank or broken areas in the waveforms or curves. These blank or broken areas indicate that the bearing is experiencing stagnation or jamming during rotation. This helps determine whether the outer ring of the bearing is experiencing stagnation or jamming. Alternatively, waveforms or curves generated from standard bearing rotation can be preset into the intelligent industrial control system. This allows the system to compare the standard waveforms or curves with the data transmitted from the test component to determine and analyze whether the outer ring rotation flexibility meets the standard, exhibits significant fluctuations, or shows stagnation or jamming. The intelligent industrial control system described above is existing technology and can serve as an intelligent information processing hub such as an industrial control computer. Because it is existing technology, its data analysis and specific structure will not be elaborated further. The waveforms or curves mentioned above are only one detection and analysis method. This method is existing technology, so its specific generation and analysis comparison will not be elaborated further. Other methods can also be used for analysis and comparison, such as generating nodes for comparison.
[0006] The present invention further includes the following configuration: the driving component includes an air pipe, the end of which is a connection end for communicating with the air outlet of an external air pump, and the beginning of which is provided with an air nozzle for compressing the airflow to make the airflow ejected at high speed. The air nozzle is detachably mounted on the bracket and is positioned facing the blade and perpendicular to the blade.
[0007] The advantages of adopting the above technical solution are as follows: In the above technology, the air pump is connected to the air outlet of an external air pump through the air pipe connection end so that the air pump is started during bearing testing, so that the air pump generates airflow and transmits it to the air pipe. Then, the air nozzle converts the airflow into high-pressure airflow and sprays it onto the blades of the impeller, thereby driving the impeller to rotate, thereby realizing the synchronous rotation of the housing, thereby realizing the rotation of the outer ring of the bearing, thus satisfying the test of the rotation flexibility of the outer ring of the bearing, thus meeting the testing prerequisite. The air pump in the above technology is existing technology, so its structure and function will not be described in detail.
[0008] The present invention further includes the following configuration: the detection element includes a speed sensor, the output end of which is oriented toward the blade and is perpendicular to the blade.
[0009] The advantages of adopting the above technical solution are: the speed sensor is used to detect the impeller rotation frequency and number of rotations when the impeller is rotating, thereby generating a signal and transmitting it to an external intelligent industrial control system for comparison, analysis and processing; the speed sensor in the above technology is existing technology, which can be an electromagnetic induction speed sensor, a Hall effect sensor, a photosensitive sensor, etc., and since it is existing technology, its structure and function will not be described in detail.
[0010] The present invention further includes: a locking hole for communicating with the receiving groove is provided on the outer peripheral wall of the housing; the locking member includes a locking shaft for threaded connection with the locking hole; and the end of the locking shaft is a locking end for cooperating with the outer ring of the bearing to be tested in the outside.
[0011] The advantages of adopting the above technical solution are: after the bearing to be tested is installed into the receiving groove, the operator can screw in the locking shaft so that the locking end of the locking shaft abuts against the outer ring of the bearing, thereby realizing the limitation and fixation of the bearing in the housing, so as to ensure the synchronous rotation of the bearing when the housing rotates; in the above technology, the connection between the locking end and the bearing can be achieved by opening a preset hole on the outer ring of the bearing according to actual needs, and the connection between the locking shaft and the outer ring of the bearing can be further realized through the threaded connection between the locking end and the preset hole, thereby further improving the connection strength.
[0012] The present invention further includes: a connecting plate is provided at the bottom of the transmission shaft, and a number of connecting bolts are detachably connected between the connecting plate and the housing.
[0013] The advantages of adopting the above technical solution are: the connecting plate in the above technology is used to connect with the housing through connecting bolts to ensure the synchronous rotation of the housing when the drive shaft rotates; the housing is detachably connected to the connecting plate through connecting bolts, which allows the operator to replace the housing with a different receiving groove diameter according to the bearing to be tested with a different diameter, thereby improving the detection range.
[0014] This utility model further includes the following features: a mandrel is provided on the base for insertion into the inner ring hole of the bearing to be tested. The mandrel is coaxially aligned with the transmission shaft. A limiting shaft is coaxially connected to the bottom of the mandrel. A limiting post is provided on the base corresponding to the position of the limiting shaft. The limiting post has a limiting hole along its height direction for the insertion of the limiting shaft. A deformation groove is provided on the outer peripheral wall of the limiting post along its height direction. The deformation groove communicates with the top wall of the limiting post and is connected to the limiting hole. A clamp is fitted on the outer peripheral wall of the limiting post for clamping the limiting post so that the limiting shaft is relatively fixed in the limiting hole. A support disc is provided between the limiting shaft and the mandrel for contacting the side wall of the inner ring of the bearing to be tested to support the inner ring of the bearing to be tested.
[0015] The advantages of adopting the above technical solution are as follows: The mandrel and support plate in the above technology are used to support the inner ring of the bearing, thereby reducing the frequency of shaking or loosening of the inner ring when the outer ring of the bearing rotates, and avoiding any impact on the rotation of the outer ring, thus improving detection accuracy and efficiency. In the above technology, the clamp is used to tighten the limiting post to reduce the deformation groove, making the inner circumferential wall of the limiting hole and the outer circumferential wall of the limiting shaft fit tightly, thereby fixing the mandrel. Simultaneously, the clamp allows for adjustment of the deformation groove width, enabling limiting shafts of different diameters to be fixed in the limiting hole. This means that operators can replace mandrels and support plates of different diameters according to the bearing inner ring diameter to fit the inner ring of the bearing to be inspected, thereby improving detection efficiency and detection range. The clamp in the above technology is existing technology, so its structure and function will not be described in detail. Attached Figure Description
