Description

Technical Field

[0001] This utility model relates to the field of air conditioner compressor bearing testing technology, and in particular to an air conditioner compressor bearing testing device. Background Technology

[0002] In air conditioning systems, the compressor is a core component, and its operating condition directly affects the performance and reliability of the entire system. The bearings inside the compressor, as key components supporting rotating parts and reducing friction, play a crucial role in the stable operation of the compressor. If the bearings fail, it will not only lead to increased compressor vibration and noise, but may also cause more serious mechanical damage. Therefore, it is necessary to inspect the air conditioning compressor bearings.

[0003] During the actual operation of bearings, due to the long-term effects of alternating loads, friction and wear, and temperature changes, loosening can easily occur between the inner and outer rings of the bearing. This loosening will aggravate the wear of the bearing, and the bearing's operation will also be affected when it is in different temperature environments and when different lubricating oils are used.

[0004] Therefore, it is necessary to design an air conditioning compressor bearing testing device that can perform tests under different temperatures and with different lubricating oils, and can detect the looseness between the inner and outer rings of the bearing, thus facilitating the detection of bearing wear. Utility Model Content

[0005] To overcome the shortcomings of bearings, which are prone to loosening between the inner and outer rings due to long-term alternating loads, friction and wear, and temperature changes during actual operation, this invention provides an air conditioning compressor bearing testing device that can detect the loosening between the inner and outer rings of the bearing under different temperatures and with different lubricating oils, thus facilitating the detection of bearing wear.

[0006] The technical implementation scheme of this utility model is as follows: an air conditioner compressor bearing testing device, comprising a test chamber, a lubricating oil tank, a motor, a threaded column, a locking ring, a first cylinder, a clamping block, a connecting frame, a vibration sensor, a second temperature sensor, a delivery pipe, a heating component, and a pushing component. The upper right part of the test chamber is connected to the lubricating oil tank, and the right side of the test chamber is connected to the motor. The motor and the processor are electrically connected via a control module. A threaded column is connected to the motor output shaft, and a locking ring is threaded onto the threaded column. Two connecting frames are connected inside the test chamber, with a first cylinder connected to each connecting frame on the side closest to each other. The first cylinder and the processor are electrically connected via a control module. A clamping block is connected to the telescopic end of each first cylinder. A vibration sensor is connected to the left clamping block, and a second temperature sensor is connected to the right clamping block. A delivery pipe is connected to the left side of the lubricating oil tank. The test chamber is equipped with a heating component capable of simulating test conditions under different temperature environments. Each connecting frame is equipped with a pushing component capable of detecting looseness between the inner and outer rings of the bearing.

[0007] Furthermore, the locking ring has anti-slip texture.

[0008] Furthermore, all the clamping blocks are arc-shaped structures.

[0009] Furthermore, the delivery pipe is a corrugated pipe.

[0010] Furthermore, the heating assembly includes a heater and a first temperature sensor. The heater is connected to the upper inner side of the test chamber, and the first temperature sensor is connected to the upper front of the test chamber. The first temperature sensor is located in front of the heater.

[0011] Furthermore, it also includes a pushing component, which includes a second cylinder and a pressure plate. The upper part of the connecting frame is connected to the second cylinder. The second cylinder and the processor are electrically connected through the control module. The extension and retraction ends of the second cylinder are all connected to the pressure plate.

[0012] The present invention has the following advantages: 1. The present invention uses a heater to simulate different temperature environments, and delivers lubricating oil to the bearing surface by changing the lubricating oil. The pressure plate moves upward to squeeze the outer ring of the bearing, and the looseness between the inner and outer rings of the bearing is observed. This achieves the effect of being able to perform testing under different temperatures and with different lubricating oils, and can detect the looseness between the inner and outer rings of the bearing, which is convenient for detecting the wear of the bearing.

[0013] 2. This utility model uses a vibration sensor to detect the vibration generated by the bearing during rotation and a second temperature sensor to detect the temperature generated by the bearing during rotation. The more severe the wear of the bearing, the greater the vibration detected by the vibration sensor and the higher the temperature detected by the second temperature sensor. This allows for vibration and temperature detection during bearing rotation, facilitating the detection of bearing wear. Attached Figure Description

Detailed Implementation

[0021] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] An air conditioner compressor bearing testing device, such as Figures 1-6As shown, the system includes a test chamber 1, a lubricating oil tank 2, a motor 5, a threaded post 6, a locking ring 7, a first cylinder 8, a clamping block 9, a connecting frame 12, a vibration sensor 13, a second temperature sensor 14, a delivery pipe 15, a heating assembly, and a pushing assembly. The lubricating oil tank 2 is connected to the upper right of the test chamber 1, and the motor 5 is connected to the right side of the test chamber 1. The motor 5 and the processor are electrically connected via a control module. A threaded post 6 is connected to the output shaft of the motor 5, and a locking ring 7 is threaded onto the threaded post 6. The locking ring 7 has anti-slip textures for easy gripping. The interior of the test chamber 1... Two connecting frames 12 are connected, one on the left and one on the right. A first cylinder 8 is connected to each connecting frame 12 on the side closest to each other. The first cylinder 8 and the processor are electrically connected through a control module. A clamping block 9 is connected to the telescopic end of the first cylinder 8. The clamping blocks 9 are all arc-shaped for easy clamping. A vibration sensor 13 is connected to the left clamping block 9, and a second temperature sensor 14 is connected to the right clamping block 9. A delivery pipe 15 is connected to the left side of the lubricating oil tank 2. The delivery pipe 15 is a corrugated pipe for easy deformation. A heating component is provided on the test chamber 1, and a pushing component is provided on each connecting frame 12.

[0023] like Figure 2 As shown, the heating assembly includes a heater 3 and a first temperature sensor 4. The heater 3 is connected to the inner side of the upper part of the test chamber 1, and the first temperature sensor 4 is connected to the upper front part of the test chamber 1. The first temperature sensor 4 is located in front of the heater 3.

[0024] like Figure 3 As shown, it also includes a pushing assembly, which includes a second cylinder 10 and a pressure plate 11. The upper part of the connecting frame 12 is connected to the second cylinder 10. The second cylinder 10 and the processor are electrically connected through the control module. The extension end of the second cylinder 10 is connected to the pressure plate 11.

[0025] When using this device, first place the test chamber 1 in the air conditioning compressor bearing detection area, then put the bearing on the threaded post 6, and then rotate the locking ring 7 so that the locking ring 7 moves downward through the thread, so that the locking ring 7 contacts the inner ring of the bearing, and fixes the inner ring of the bearing to the threaded post 6. Then, the processor starts the first cylinder 8 through the control module, which drives the clamping block 9 to move, so that the clamping block 9 moves closer to each other to clamp the outer ring of the bearing. Then, the motor 5 is started to drive the inner ring of the bearing to rotate. The vibration sensor 13 detects the vibration generated by the bearing when rotating, and the second temperature sensor 14 detects the temperature generated by the bearing when rotating. When the bearing wear is more severe, the vibration sensor 13 will detect the greater the vibration, and the temperature sensor 14 will detect the higher the temperature. Thus, vibration and temperature detection can be performed when the bearing rotates, which is convenient for detecting the wear of the bearing.

[0026] When testing is required under different temperature conditions, heater 3 can be activated to heat the test chamber 1. The temperature inside the test chamber 1 is detected by the first temperature sensor 4 to simulate testing under different temperature conditions. Then, lubricating oil is connected to the lubricating oil tank 2 and delivered to the bearing surface through the delivery pipe 15. The bearing operation is tested by changing different lubricating oils. After that, the first cylinder 8 is activated to move the clamping block 9 outward. Then, the second cylinder 10 on the connecting frame 12 is activated to move the pressure plate 11 upward to squeeze the outer ring of the bearing. The pressure sensor built into the pressure plate 11 detects the applied pressure. The wear condition of the bearing is judged by observing the looseness between the inner and outer rings of the bearing. Thus, testing can be carried out under different temperatures and with different lubricating oils, and the looseness between the inner and outer rings of the bearing can be detected, which is convenient for detecting the wear condition of the bearing.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
