Description

A dynamic lubrication film application device for measuring the performance of sliding bearings Technical Field

[0001] This application relates to the field of lubricant addition technology, and in particular to a dynamic lubrication film application device for measuring the performance of sliding bearings. Background Technology

[0002] In the performance testing of sliding bearings, in order to accurately measure the performance of sliding bearings, it is necessary to add lubricating oil to the bearing bush during the measurement process to ensure the normal rotation of the shaft during the performance measurement and to avoid test errors or bearing damage caused by insufficient or uneven distribution of lubricating oil. A filling device is required when adding lubricating oil to the sliding bearing during the measurement.

[0003] The current lubrication device for adding lubricating oil to sliding bearings during measurement mainly consists of a heated oil tank, an oil pump installed at the oil outlet of the oil tank, an oil outlet pipe installed at the oil pump outlet, a single return oil filter installed at the oil return port of the oil tank, a return oil pump installed at the oil inlet of the return oil filter, and a return oil pipe installed at the oil inlet of the return oil pump. In use, this lubricating oil filling device primarily uses the oil pump to add lubricating oil from the oil tank to the sliding bearing during measurement via the oil injection pipe. Then, the return oil pump and return oil pipe are used to extract the lubricating oil from the sliding bearing bush, and the oil is filtered through the return oil filter before returning to the oil tank for recycling. This achieves dynamic addition of the lubricating oil film during the sliding bearing measurement process.

[0004] Existing lubrication devices for adding lubricating oil to sliding bearings during measurement can dynamically add lubricating oil to the inside of the sliding bearing bush. However, as the dynamic addition of lubricating oil continues, more and more impurities accumulate in the return oil filter. Excessive impurities reduce the filtration speed of the return oil filter, resulting in slower lubricating oil recovery. This causes fluctuations in the thickness of the lubricating oil film inside the sliding bearing bush, leading to significant errors in the measurement results of the sliding bearing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a dynamic lubricating film filling device for measuring the performance of sliding bearings. This device allows two return oil filters at the return oil side of the storage tank to be used alternately during the dynamic addition of lubricating oil film. This ensures that while one return oil filter is being cleaned, the other can be used normally, thus guaranteeing the normal progress of the lubricating oil film addition process for sliding bearings and avoiding the drawback of fluctuating lubricating oil film thickness in sliding bearings due to excessive impurities in the return oil filter causing slow return oil speed.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] To better understand the technical solutions shown in the embodiments of this application, the structure and working principle of an existing filling device for adding lubricating oil to a sliding bearing in a measurement process will be introduced first.

[0023] The existing lubrication device for adding lubricating oil to sliding bearings during measurement mainly consists of an oil tank with a built-in heating function, an oil pump installed at the oil outlet of the oil tank, an oil outlet pipe installed at the oil pump outlet, a single return oil filter installed at the oil return port of the oil tank, a return oil pump installed at the oil inlet of the return oil filter, and a return oil pipe installed at the oil inlet of the return oil pump. In use, this type of lubricating oil filling device primarily uses the oil pump to add lubricating oil from the oil tank to the sliding bearing during measurement via the oil injection pipe. Then, the return oil pump and return oil pipe are used to extract the lubricating oil from the sliding bearing bush, and the oil is filtered through the return oil filter before returning to the oil tank for recycling. This achieves dynamic addition of the lubricating oil film during the sliding bearing measurement process.

[0024] Please refer to Figures 1-3, which illustrate a dynamic lubrication film application device for measuring the performance of sliding bearings disclosed in this application. The device includes a support platform 5, with an oil reservoir 1 mounted at the upper center of the support platform 5. An oil injection mechanism 3 is mounted on the oil outlet side of the oil reservoir 1 on the support platform 5, and a return oil filter mechanism 6 is mounted on the oil return side of the oil reservoir 1 on the support platform 5. The oil injection mechanism 3 includes an oil pump 31 and an oil injection pipe 32. The oil pump 31 is mounted on the support platform 5, and the oil injection pipe 32 is installed at the oil outlet of the oil pump 31. The return oil filter mechanism 6 includes an oil outlet pipe 61, a return oil filter 62, a valve 63, and an oil inlet pipe 64. 4. Return oil pump 65, return oil pipe 66, and valve 67. There are two return oil filters 62, which are symmetrically installed on the upper end of the support platform 5. The oil inlet of the two return oil filters 62 is connected to a U-shaped oil inlet pipe 64. A valve 63 is installed at the upper end of the oil inlet pipe 64 where it connects to each return oil filter 62. An oil outlet pipe 61 is installed at the oil outlet of each of the two return oil filters 62. A valve 67 is installed at the bottom end of the oil outlet pipe 61. The oil inlet of the oil inlet pipe 64 is connected to the return oil pump 65, and the oil inlet of the return oil pump 65 is connected to the return oil pipe 66.

[0025] Specifically, when dynamically adding a lubricating oil film to the sliding bearing being measured, the oil injection pipe 32 is first connected to the oil inlet on the sliding bearing, and the oil return pipe 66 is connected to the oil outlet on the sliding bearing. Then, under the action of the oil pump 31, the lubricating oil in the oil storage tank 1 is added to the sliding bearing being measured through the oil injection pipe 32. Then, the lubricating oil in the sliding bearing bush is extracted by the oil return pump 65 and the oil return pipe 66, and the oil is filtered by the oil return filter 62 and re-enters the oil storage tank 1 for recycling. This achieves the dynamic addition of the lubricating oil film during the measurement of the sliding bearing.

[0026] Please refer to Figures 1 and 3. An automatic refueling mechanism 2 is installed on the upper back of the oil tank 1. The automatic refueling mechanism 2 includes a refueling pipe 21, a refueling pump 22, a support plate 23, and a liquid level sensor 24.

[0027] As one implementation method, when the level sensor 24 detects that the amount of oil in the oil tank 1 has reached the warning value, the oil pump 22 will start. After the oil pump 22 starts, it will pump new lubricating oil from the external storage container to the oil tank 1 through the oil filling pipe 21, so as to realize the automatic addition of lubricating oil and save the tedious operation of manual addition.

[0028] Please refer to Figures 1 and 3. The support plate 23 is welded to the oil storage tank 1. The oil pump 22 is installed on the upper side of the support plate 23. The oil pump pipe 21 is installed between the oil outlet of the oil pump 22 and the top of the oil storage tank 1. The liquid level sensor 24 is installed on one side of the top of the oil storage tank 1.

[0029] As one implementation method, the support plate 23 is mainly used to provide stable support for the fuel pump 22, ensuring the convenient use of the fuel pump 22. The fuel pump 22 is mainly used to deliver new external lubricating oil into the fuel pipe 21, so as to realize the convenient addition of lubricating oil into the oil storage tank 1.

[0030] Please refer to Figure 3. Electric heating plates 8 are also installed on the lower part of the two side walls inside the oil tank 1, and a temperature sensor 7 is installed on the lower part of the other side wall inside the oil tank 1.

[0031] As one implementation method, the electric heating plate 8 is mainly used to heat the lubricating oil in the oil tank 1 to ensure that the viscosity of the lubricating oil is suitable and to facilitate the delivery of the lubricating oil. At the same time, the temperature sensor 7 can measure the temperature of the lubricating oil to ensure the stability of the lubricating oil temperature in the oil tank 1.

[0032] Please refer to Figure 1. A touch panel 4 is installed on one side of the top of the support platform 5. The touch panel 4 is electrically connected to the oil pump 22, the oil transfer pump 31, the oil return pump 65, the temperature sensor 7, the electric heating plate 8, and the liquid level sensor 24.

[0033] As one implementation, the touch panel 4 has a built-in microprocessor, which is mainly used to coordinate the operation of the oil pump 22, the oil delivery pump 31, the return oil pump 65, the temperature sensor 7, the electric heating plate 8, and the liquid level sensor 24 to ensure the convenient addition of lubricating oil to the sliding bearing in the measurement.

[0034] Please refer to Figure 1. The oil pump 31 is connected to the oil outlet of the oil storage tank 1 through a pipeline. The oil pump 31 is connected to the oil injection pipe 32 by a flange. The oil injection pipe 32 is equipped with a flow regulating valve.

[0035] In one implementation, the oil pump 31 is mainly used to transport the lubricating oil in the oil storage tank 1 to the oil injection pipe 32, so that the lubricating oil can be added to the sliding bearing in the measurement through the oil injection pipe 32, and the flow regulating valve can control the flow rate of the oil injection.

[0036] Please refer to Figures 1-2. The return oil pipe 66 is connected to the return oil pump 65 flange, the inlet oil pipe 64 is connected to the return oil filter 62 flange, and the housing of valve 63 is bolted to the return oil pipe 66.

[0037] As one implementation method, the return oil pipe 66 can ensure convenient suction of lubricating oil in the sliding bearing, and the inlet oil pipe 64 can ensure convenient entry of the suctioned lubricating oil into the return oil filter 62. The return oil filter 62 is a filter bag type oil filter, mainly used to filter impurities in the lubricating oil.

[0038] Please refer to Figures 1-2. The oil outlet pipe 61 is connected to the return oil filter 62 flange, and the oil outlet pipe 61 is connected to the inside of the oil storage tank 1.

[0039] As one implementation method, the flange connection makes the connection between the oil outlet pipe 61 and the return oil filter 62 more secure, and the connection between the oil outlet pipe 61 and the inside of the oil storage tank 1 can ensure the convenient return of the filtered lubricating oil to the oil storage tank 1.

[0040] The specific working principle is as follows: When dynamically adding a lubricating oil film to the sliding bearing being measured, the oil injection pipe 32 is first connected to the oil inlet on the sliding bearing, and the oil return pipe 66 is connected to the oil outlet on the sliding bearing. Then, under the action of the oil pump 31, the lubricating oil in the oil storage tank 1 is added to the sliding bearing being measured through the oil injection pipe 32. Afterwards, the lubricating oil in the sliding bearing bush is extracted by the oil return pump 65 and the oil return pipe 66, and the oil is filtered through the oil return filter 62 and then re-enters the oil storage tank 1 for recycling. This achieves the sliding bearing measurement... During the measurement process, the lubricating oil film is dynamically added. During this process, the two return oil filters 62 at the oil return side of the storage tank are alternately used by controlling the opening and closing of valve 63 and valve 67. This allows the other return oil filter 62 to be used normally while one is being cleaned, ensuring the normal progress of the lubricating oil film addition process for the sliding bearing. This avoids the drawback of the lubricating oil film thickness fluctuation in the sliding bearing caused by too many impurities in the return oil filter 62 leading to a slow return oil speed. This makes the measurement results of the sliding bearing more accurate.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
