In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specified otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the related art, the SRV5 equipment is used for grease wear resistance testing. The SRV5 equipment is equipment for detecting the wear resistance of lubricating grease, and is composed of a clamp, a test ball and a test disc, when the SRV5 equipment is used, the clamp is used for clamping the test ball and applying a test load to the test ball, so that a friction test is performed on the test ball and the test disc which is horizontally placed and coated with the lubricating grease, and the wear resistance of the lubricating grease is obtained according to a grinding mark on the test ball after the test is finished.

Because the clamp is unstable, the test load applied to the test ball can change, so that the result of the wear resistance of the lubricating grease obtained by detection is influenced, and the accuracy of the wear resistance detection of the lubricating grease is not high. Meanwhile, if the test is performed only through the friction between one part and the rolling part, experimental deviation may occur, resulting in inaccurate test results. In addition, the conditions under which greases are used may be more extreme and harsh in real-world situations. Therefore, it is also necessary to test the anti-wear properties of greases under different temperature conditions.

Based on this, the detection system that this application embodiment provided, through the form of changing the applied load, improve the area of contact friction and simulate different temperature conditions, in order to solve at least some of the above-mentioned problems.

In the embodiment of the present application, a receiving chamber having an opening at one end is formed in the first housing 101.

Specifically, referring to fig. 1 and 2, a case where the upper end of the first casing 101 is open is illustrated, an accommodating cavity which is open upward is formed in the first casing 101, a temperature-resistant hard transparent acrylic plate is provided right in front of the first casing 101 (i.e., in a front direction illustrated in fig. 1, corresponding to a right direction illustrated in fig. 2), three permanent magnets 113 are provided in the acrylic plate, and the acrylic plate is adsorbed to the first casing 101 through two upper left and right permanent magnets 113, and adsorbed to the heating device 105 through one lower middle permanent magnet 113. The acrylic plate directly in front of the first housing 101 is used to block the grease from flowing out, and can be opened and closed to check the condition in the receiving cavity of the first housing 101. The other surface of the first housing 101 may be made of steel or other high temperature resistant materials, and is not limited herein.

A base 102 is disposed in the receiving cavity, the base 102 having a first surface facing the opening, the first surface of the base 102 being for bearing grease. Specifically, with reference to fig. 1 and fig. 2, the base 102 is disposed in the accommodating cavity of the first housing 101, the base 102 is a steel casting, an upper surface of the base 102 is a first surface, and grease is applied on the first surface.

The "first surface" may be a flat surface or a concave surface. When the first surface is a plane, the grease is coated on the first surface. When the first surface is concave, more grease can be accommodated. The method can be set according to actual use conditions, and the method is not particularly limited in the embodiment of the application.

The rolling member 103 is provided on a first surface of the base 102, and the rolling member 103 is configured to be capable of rolling on the first surface of the base 102. Alternatively, the rolling elements 103 may be bearing steel balls or bearing steel rollers. Taking fig. 1 and 2 as an example, the rolling members 103 are steel bearing balls, and are spherical objects, and the rolling members 103 can roll on the first surface of the base 102.

The platen 104 is configured to be sealable to the opening to form a closed receiving cavity, and the platen 104 is further configured to be movable in a direction towards or away from the first surface of the base to provide a load on the rolling elements 103.

Specifically, referring to fig. 1 and 2, the platen 104 can be covered above the first housing 101 so that the first housing 101 forms a closed accommodating chamber, and the platen 104 can move up and down to provide a load to the rolling members 103. That is, by adjusting the position of the platen 104, the adjustment of the load size can be achieved. Optionally, the platen 104 is a steel casting. The reason that the platen 104 is designed as the steel casting is because the steel casting has greater design flexibility, the design of using the steel casting can have the greatest degree of freedom in selecting the shape and size of the casting, the steel casting is easy to form and change the shape, a finished product can be quickly manufactured according to a drawing, the manufacturing time is shortened, and the steel casting has the strongest flexibility and changeability of metallurgical manufacturing.

Specifically, a temperature probe is also provided within the heating device 105. The temperature in the accommodating cavity can be acquired in real time through the temperature probe.

The detection system is provided by arranging the base 102 in the accommodating cavity of the first housing 101, wherein the first surface of the base 102 is used for bearing lubricating grease, arranging the rolling members 103 on the first surface of the base 102, providing load to the rolling members 103 through the pressure plate 104, and providing different temperature environments through the arrangement of the heating device 105. Therefore, in the embodiment, by providing the movable pressure plate 104, not only different stable loads can be provided for the rolling members 103, but also friction can be generated between the base 102 and the rolling members 103, so that the friction contact area of the rolling members 103 is increased. Meanwhile, by providing the heating device 105, different working environments can be simulated. Therefore, the detection system provided by the application improves the accuracy of the detection of the wear resistance of the lubricating grease.

The inventor of the present application has found that, if a friction test is performed on a certain point or a certain surface of a rolling member, the obtained test result cannot be applied to reality. Thus, in some embodiments, with continued reference to fig. 1, a side surface of the platen 104 facing the first surface of the base 102 is configured as a first arc.

Specifically, in some embodiments, as shown in fig. 1, a side surface of the platen 104 facing the first surface is convex in a direction facing the first surface of the base 102 to form a first arc surface. In some embodiments, a side surface of the platen 104 facing the first surface may be recessed toward the first surface of the base 102 to form a first arc surface. It should be noted that the first arc surface formed by the protrusion has a smaller contact area with the rolling member 103 than the first arc surface formed by the recess. The first arc surface formed in different manners can be selected according to an actual application scenario, which is not specifically limited in the embodiment of the present application.

So, through the first cambered surface of constructing pressure disk 104, can guarantee that the lower surface of pressure disk 104 and rolling member 103 contact each other, and then make the whole sphere of rolling member 103 can both rub, more laminate the rolling motion operating mode of bearing among the actual life, consequently the grease wear resistance that obtains is more accurate.

In some embodiments, with continued reference to fig. 1, the first surface of the base 102 is configured to include a second arc. Specifically, the first surface of the base 102 is recessed away from the opening to form a second arc. For example, the second cambered surface can be a hemispherical profile or a U-shaped profile. Fig. 1 illustrates a situation where the first surface of the base is configured as a U-profile.

Therefore, the upper surface of the base 102 is a U-shaped surface, so that the rolling part 103 can roll on the U-shaped surface of the base 102, the lubricating grease is smeared on the U-shaped surface, the lubricating grease can be turned over when the rolling part 103 rolls on the U-shaped surface, the rolling part 103 can be fully contacted with the lubricating grease, the contact area of the lubricating grease is increased, the rolling of a bearing is simulated, and the detection process of the anti-wear performance of the lubricating grease is better realized.

In an embodiment of the application, the detection system further comprises a drive device. The driving device is in transmission connection with the rolling member 103 and is used for providing a rotary driving force for the rolling member 103. The drive means may be used to control the speed of rotation of the rolling elements. Optionally, the drive means is a drive motor. Of course, the driving device may also be a rotating mechanical device as long as the rolling of the rolling member 103 can be realized, and the embodiment of the present application does not specifically limit this.

Specifically, referring to fig. 1 and 2, the central axial hollow surface of the rolling member 103 has an internal thread adapted to the driving link 107, so that one end of the driving link 107 is connected to the driving motor 106 and the other end is connected to the rolling member 103. The driving motor 106 drives the driving connecting rod 107, thereby driving the rolling member 103 to rotate. The driving motor 106 is fixed to the rear side of the second housing 112 (i.e. the rear direction indicated in fig. 1 corresponds to the left direction indicated in fig. 2), the driving motor 106 is an electromagnetic driving motor, a rotational speed sensor is arranged in the electromagnetic driving motor, the rotational speed is not less than 6000r/min, the highest rotational speed is 7500r/min, the rotational speed is too low, the rolling member 103 cannot be driven to rotate, resource waste is caused, the rolling member 103 may fly down due to too high rotational speed, equipment is damaged, and even personnel danger is caused. The rotating speed of the rolling element 103 can be obtained in real time through the rotating speed sensor.

In an embodiment of the application, the detection system further comprises a compression pump 108 and an air compressor 109 connected to the compression pump 108. The compression pump 108 provides a driving force acting on the platen by means of an air compressor 109.

Specifically, referring to fig. 1 and 2, the compression pump 108 is perpendicular to the upper side of the rolling member 103, and is fixed to the top inside the second housing 112 (i.e., in the upward direction shown in fig. 1 and 2), the air compressor 109 is connected to the compression pump 108, the compression connecting rod 110 is a cylindrical steel rod, one end of the rod is connected to the compression pump 108, and the other end of the rod is connected to a threaded rod protruding from the center of the second surface of the pressure plate 104. The compression connecting rod 110 and the pressure plate 104 are driven by the air compressor 109 and the compression pump 108 to provide load for the rolling members 103, and the compression pump 108 is internally provided with a pressure sensor. The load provided for the test ball can be acquired in real time through the pressure sensor.

In this embodiment, the air compressor 109 and the compression pump 108 drive the pressure plate 104 to provide a load for the rolling elements 103, and the provided load is more stable, so as to ensure the accuracy of the detection of the wear resistance of the grease.

In an embodiment of the application, the detection system further comprises a buffer means 111. The buffer device 111 is disposed between the base 102 and the platen 104.

Specifically, referring to fig. 1 and 2, the buffer devices 111 are made of a silicone elastomer, and are disposed between the platen 104 and the base 102, specifically on two sides of the U-shaped protrusion of the base 102, the lengths of the two buffer devices 111 are the same as the lengths of the two sides of the U-shaped protrusion of the base 102, and the widths of the two buffer devices 111 are the same as the widths of the two sides of the U-shaped protrusion of the base 102. The thickness of the buffer 111 is 5-15 mm. The reason why the thickness of the buffer device 111 is 5-15mm is that if the buffer device 111 is designed to be too thin, the buffer device will not protect the base 102, and if the buffer device 111 is designed to be too thick, the contact between the rolling member 103 and the pressure plate 104 will be affected, so that the load will be changed, and the detection result of the anti-wear performance of the grease will be affected.

In this embodiment, the buffer device 111 can protect the base 102, prevent the base 102 from being damaged when the pressure plate 104 provides a load to the rolling members 103 downward, and avoid the possible danger caused by the damage of the base 102.

Directly in front of the second casing 112 (i.e., in a front direction shown in fig. 1, corresponding to a right direction shown in fig. 2), a heat-resistant hard transparent acrylic plate is provided, which incorporates four permanent magnets 113, and is attached to the second casing 112 via two left and right permanent magnets 113, so that the acrylic plate can be opened or closed. The other surface of the second housing 112 may be made of steel or other high temperature resistant materials, which is not limited herein. It is preferred that the second housing 112 be made of a steel casting because the steel casting provides greater design flexibility, the steel casting allows for the greatest freedom of choice in the shape and size of the casting, the steel casting is easily shaped and can be changed in shape, the finished product can be quickly made according to the drawings, the manufacturing time is shortened, and the steel casting provides the greatest flexibility and variability in metallurgical manufacturing.

The external host 114 in the detection system is in signal connection with the compression pump 108, the heating device 105 and the driving motor 106 respectively, and can control the load, the temperature and the rotating speed in real time. The signal connection mode may be a wired connection, a wireless connection, or a signal connection through WIFI, a mobile cellular network, or NFC (Near Field Communication), which is not limited herein. An alarm program is built in the external host 114, and when monitoring that the real-time parameters of load, temperature and rotating speed are abnormal, an alarm is given out, so that the working personnel can notice the dangerous situation and react in time, and the occurrence of greater danger is avoided.

Based on the above detection system, the following description will be made in detail for a method for detecting the wear resistance of the grease by using the detection system.

Fig. 3 shows a schematic flow chart of a method for detecting wear resistance of grease provided in an embodiment of the present invention.

Referring to fig. 3, the present embodiment relates to an implementation manner of how to utilize the detection device to perform grease wear resistance detection. On the basis of the embodiment, the method comprises the following steps:

The preset test conditions comprise a preset test initial temperature, a preset test initial load, a preset test initial rotating speed and a preset test duration.

In the present embodiment, the test conditions are preset by the external host computer 114, that is, the external host computer 114 controls the compression pump 108 to provide a preset test initial load to the rolling member 103, the external host computer 114 controls the heating device 105 to provide a preset test initial temperature to the accommodating cavity of the first housing 101, and the external host computer 114 controls the driving motor 106 to provide a preset test initial rotation speed to the rolling member 103.

And S302, monitoring test parameters generated in the friction test process in real time, and stopping the friction test if the test parameters are abnormal.

The test parameters comprise test real-time temperature, test real-time load and test real-time rotating speed.

In this embodiment, a pressure sensor in the compression pump 108 is used to obtain a test real-time load, a temperature probe in the heating device 105 is used to obtain a test real-time temperature, a rotation speed sensor in the driving motor 106 is used to obtain a test real-time rotation speed, the obtained test real-time temperature, test real-time load and test real-time rotation speed are transmitted to the external host 114, and whether the test parameters are abnormal or not is determined in the external host 114. The abnormal test parameter means that the difference value between the test real-time temperature and the preset test initial temperature is greater than a preset temperature threshold value, or the ratio of the test real-time load to the preset test initial load is greater than a preset load threshold value, or the ratio of the test real-time rotating speed to the preset test initial rotating speed is greater than a preset rotating speed threshold value. An alarm program is installed in the external host 114, and when the test parameters are detected to be abnormal, the detection system is controlled to pause, and an alarm is given out, so that the working personnel can notice the dangerous condition and react in time, and the occurrence of greater danger is avoided.

Specifically, the test real-time load is increased by 10% compared with the preset test initial load, the test real-time temperature is higher than the preset test initial temperature by 20-30 ℃, and the test real-time rotating speed is reduced by 10% compared with the preset test initial rotating speed.

S303, obtaining the image of the rolling part after the friction test is stopped, and obtaining the anti-wear performance of the lubricating grease according to the image.

In this embodiment, if the test parameters are abnormal, the friction test is stopped, an image of the rolling member after the friction test is stopped is obtained, the width of a wear scar on the image is measured, and the wear resistance of the grease is obtained according to the width of the wear scar; if the test parameters are not abnormal, acquiring an image of the rolling part after the friction test with preset test duration is finished, measuring the width of a grinding crack on the image, and obtaining the wear resistance of the lubricating grease according to the width of the grinding crack.

Taking a specific example of a process of performing a grease wear resistance detection test on a grease sample a and a grease sample B, fig. 4 is a schematic flow chart of a grease wear resistance detection test provided in an embodiment of the present invention, and referring to fig. 4, this embodiment relates to an implementation manner of a detection test for determining whether the grease wear resistance of a grease sample is good or bad. On the basis of the above embodiment, the grease wear resistance test comprises the following steps:

S404, presetting test parameters, wherein the test parameters comprise: load, temperature, speed, duration.

For example, a preset test load of 500N, a preset test temperature of 150 ℃, a preset test rotation speed of 6000r/min, and a preset test duration of 10h are set by the external host computer 114.

S405, starting the heating device.

For example, the external host 114 controls the heating device 105 to be powered on, and the temperature rises to reach the preset test temperature of 150 ℃.

And S406, applying a preset test load to the rolling piece through the compression pump, the compression connecting rod and the pressure plate.

For example, the external host 114 controls the compression pump 108 to continuously request a certain amount of compressed air from the air compressor 109, and the compression pump 103 uses the compressed air to drive the platen 104 to continuously move downwards through the compression connecting rod 110, so as to apply a preset test load 500N to the rolling members 103.

And S407, applying a preset test rotating speed to the rolling piece through the driving motor and the driving connecting rod, and driving the rolling piece to rotate on the base.

For example, the external host computer 114 controls the driving motor 106 to drive the rolling member 103 to rotate through the driving connecting rod 107, so that the rolling member 103 reaches the preset test rotation speed of 6000 r/min.

And S408, monitoring the detection system in real time through an external host.

For example, the load, the temperature and the rotation speed are monitored in real time by the external host 114, and if the real-time load is increased by 10% compared with the preset test load, or the real-time temperature is higher than the preset test temperature by 20 ℃ to more than 30 ℃, or the real-time rotation speed is decreased by 10% compared with the preset test rotation speed, the external host 114 controls the detection system to stop working and gives an alarm.

The grease sample a was subjected to the grease wear resistance test through the steps of S401 to S408 described above, and the grease sample B was also subjected to the grease wear resistance test through the steps of S401 to S408 described above.
