Description

Technical Field

[0001] The utility model relates to the technical field of lubricating grease testing, in particular to a lubricating grease testing bench. Background Art

[0002] During the installation of equipment, lubricating grease needs to be added to bearings, gears and other joints to achieve lubrication. Different lubricants have different physical properties, which results in different service lives of the lubricants.

[0003] Secondly, the service life of lubricating grease will also be different in different usage environments. For example, using lubricating grease at the seaside and in dry areas will have different salt content in the environment, which will make the service life of the lubricating grease different due to different environments.

[0004] At the same time, during the use of bearings, the usage status of the bearings is different in different installation positions. For example, micro bearings are installed in some installation positions, and the micro bearings will have a small range of deflection. If the service life of the lubricating grease is unknown in this state, the micro bearings will cause wear and tear, and the micro bearings cannot be lubricated and maintained.

[0005] During the use of existing lubricating grease, one can only use it with reference to the service life stated in the instruction manual, but cannot test its service life according to different use environments, which is inconvenient for the use of the lubricating grease.

[0050] Please refer to Figure 1-Figure 3 An embodiment of the present invention provides a lubricating grease test bench 100, the lubricating grease test bench 100 comprising:

[0051] The mounting platform 110 is provided with a test cavity 110a;

[0052] A test bearing 120 is disposed in the test cavity 110a;

[0053] A shielding assembly 130 is detachably mounted on the mounting platform 110 and partially shields the test cavity 110a;

[0054] One end of the micro-motion component 140 passes through the shielding component 130 and extends into the test cavity 110a to drive the test bearing 120 to rotate back and forth. The two end surfaces of the test bearing 120 respectively abut against the shielding component 130 and the micro-motion component 140.

[0055] In this embodiment, the test bearing 120 is installed in the test cavity 110a, and the shielding assembly 130 is installed on the mounting platform 110. A portion of the fine motion assembly 140 passes through the shielding assembly 130 and contacts the test bearing 120.

[0056] The lubricating grease to be tested is applied to the contact surface of the test bearing 120 , and the micro-motion component 140 is started to drive the test bearing 120 to reciprocate. Driven by the micro-motion component 140 , the test bearing 120 continues to reciprocate at a small angle.

[0057] After the test, the performance and service life of the lubricant are analyzed based on the collected data.

[0058] By adjusting the environmental conditions in the test chamber 110a, the performance of the lubricating grease in different environments can be tested, providing a reference for practical applications.

[0059] In at least one embodiment of the present application, the shielding assembly 130 includes:

[0060] The cover 131 defines a communication hole 131 a , through which one end of the micro-motion assembly 140 extends into the test cavity 110 a .

[0061] One end of the fastener 132 abuts against the cover 131 , and the other end is threadedly connected to the mounting platform 110 .

[0062] In at least one embodiment of the present application, a liquid injection port 131b is provided on the cover body 131, one end of the liquid injection port 131b is connected to an external peristaltic pump, and the other end is connected to the test cavity 110a, so as to inject a salt-containing liquid into the test cavity 110a.

[0063] In this embodiment, first, the test bearing 120 is installed in the test cavity 110a, and the shielding assembly 130 is used to cover the test cavity 110a. The fasteners 132 secure the cover 131 to the mounting platform 110 to ensure the sealing of the test cavity 110a.

[0064] A portion of the fine motion component 140 enters the test cavity 110 a through the communicating hole 131 a and contacts the test bearing 120 , so that the fine motion component 140 drives the test bearing 120 to perform reciprocating rotation within a certain angular range.

[0065] A saline liquid or other specific liquid is injected into the test cavity 110a through the liquid injection port 131b. The peristaltic pump controls the inflow of the liquid and adjusts the environmental conditions in the test cavity 110a.

[0066] The fine motion assembly 140 is started, and the test bearing 120 performs reciprocating motion under the drive of the fine motion assembly 140. The performance and durability of the lubricating grease are tested under different environmental conditions (such as a high salinity environment).

[0067] After the test is completed, the performance data of the lubricating grease under different conditions is collected and its service life and applicability are analyzed. For example, the wear of the test bearing 120 is measured to obtain the lubricating performance and lubricating durability of the lubricating grease.

[0068] Different environmental conditions, such as high salinity or high humidity, can be simulated through the liquid injection port 131b and the peristaltic pump, which helps to evaluate the performance of lubricating grease in various actual use environments.

[0069] The cover 131 is a circular plate, the communicating hole 131 a is a through hole, the fastener 132 is a bolt, and the liquid injection port 131 b is a through hole.

[0070] In at least one embodiment of the present application, the micro-motion assembly 140 includes:

[0071] A connecting shaft 141, one end of which is disposed in the test cavity 110a and the other end of which extends through the communicating hole 131a to the outside;

[0072] A first hydraulic assembly 142 is provided at an end of the connecting shaft 141 away from the cover 131 and is rotatably connected to the connecting shaft 141;

[0073] The second hydraulic assembly 143 is disposed at an end of the connecting shaft 141 away from the cover body 131 and is rotatably connected to the connecting shaft 141 .

[0074] In at least one embodiment of the present application, the micro-motion assembly 140 further includes:

[0075] The rotating plate 144 is provided at an end of the connecting shaft 141 away from the cover 131;

[0076] The first hydraulic assembly 142 and the second hydraulic assembly 143 are rotatably connected to two ends of the rotating plate 144 .

[0077] In at least one embodiment of the present application, the first hydraulic assembly 142 and the second hydraulic assembly 143 are symmetrically arranged on both sides of the connecting shaft 141 .

[0078] In at least one embodiment of the present application, the first hydraulic assembly 142 includes a first hydraulic cylinder 1421, a first mounting plate 1422, and a first hydraulic push rod 1423. The first hydraulic cylinder 1421 and the first hydraulic push rod 1423 are both disposed on the first mounting plate 1422, and the first hydraulic cylinder 1421 is in communication with the first hydraulic push rod 1423.

[0079] The second hydraulic assembly 143 includes a second hydraulic cylinder 1431, a second mounting plate 1432 and a second hydraulic push rod 1433. The second hydraulic cylinder 1431 and the second hydraulic push rod 1433 are both arranged on the second mounting plate 1432. The second hydraulic cylinder 1431 is connected to the second hydraulic push rod 1433. The first hydraulic push rod 1423 and the second hydraulic push rod 1433 are both rotatably connected to the connecting shaft 141.

[0080] In this embodiment, the hydraulic system is started, and the first and second hydraulic components 143 work together. The first hydraulic cylinder 1421 pushes the first hydraulic push rod 1423 to move to drive the rotating plate 144 to rotate; then the second hydraulic cylinder 1431 pushes the second hydraulic push rod 1433 to move to drive the rotating plate 144 to rotate in the opposite direction, so that the connecting shaft 141 rotates back and forth.

[0081] The movement of the connecting shaft 141 is transmitted to the test bearing 120 in the test cavity 110 a through the communicating hole 131 a , driving the test bearing 120 to perform the required reciprocating motion.

[0082] By adjusting the pressure and thrust of the hydraulic system, different operating conditions can be simulated, such as the performance of lubricating grease under different load or speed conditions.

[0083] The hydraulic system in the micro-motion assembly 140 can provide precise force and motion control, capable of simulating very fine movements.

[0084] By adjusting the parameters of the hydraulic components, a variety of working conditions can be simulated, ranging from slight swings to large-angle swings, to fully evaluate the performance of the lubricating grease.

[0085] The symmetrical design of the first and second hydraulic assemblies 143 allows the connecting shaft 141 to be evenly stressed during movement, thereby reducing vibration and wear of the test device and improving test stability and data reliability.

[0086] It should be noted that the first hydraulic assembly 142 and the second hydraulic assembly 143 are both rotatably connected to the rotating plate 144 via two rotating shafts.

[0087] The connecting shaft 141 is rod-shaped, the first mounting plate 1422 is plate-shaped, the second mounting plate 1432 is plate-shaped, and the rotating plate 144 is an arc-shaped plate.

[0088] In at least one embodiment of the present application, the micro-motion assembly 140 further includes:

[0089] The fixing plate 145 is provided at one end of the connecting shaft 141 away from the first hydraulic assembly 142. A mounting groove 141a is provided on the side of the connecting shaft 141 close to the fixing plate 145. The test bearing 120 is sleeved on the connecting shaft 141. The test bearing 120 is located in the mounting groove 141a. The two ends of the test bearing 120 are respectively in contact with the fixing plate 145 and the cover body 131.

[0090] In this embodiment, test bearing 120 is first installed in mounting groove 141a of connecting shaft 141. A fixing plate 145 is provided at one end of connecting shaft 141 to provide stable support. The ends of test bearing 120 abut against fixing plate 145 and cover 131, respectively, ensuring its fixed position.

[0091] The fine motion assembly 140 (including the connecting shaft 141, the hydraulic assembly, etc.) is activated to drive the test bearing 120 to perform reciprocating rotation. Since the test bearing 120 is located in the mounting groove 141a, its motion trajectory is precisely controlled.

[0092] During the test, the movement of the test bearing 120 will be affected by the lubricating grease. The micro-motion component 140 evaluates the performance of the lubricating grease by measuring parameters such as friction and temperature change of the bearing.

[0093] After the test is completed, data such as the wear of the lubricant and the lubrication effect are collected and analyzed to provide a basis for the selection of the lubricant.

[0094] The test bearing 120 is ensured to maintain a stable position and state during the test. The fixing plate 145 provides stable support, and the mounting groove 141a ensures the position accuracy of the test bearing 120, reduces vibration and error during the test, and provides more reliable data.

[0095] By accurately positioning the fixing plate 145 and the mounting groove 141 a , the test bench can simulate the bearing state in actual working conditions and provide a real and effective testing environment.

[0096] The fixing plate 145 is a circular plate, and the mounting groove 141 a is an annular groove provided on the outer circumferential surface of the connecting shaft 141 .

[0097] In at least one embodiment of the present application, the mounting platform 110 is formed with an accommodating space 110 b , and the accommodating space 110 b is communicated with the testing cavity 110 a ;

[0098] The lubricating grease test bench 100 further includes:

[0099] One end of the hydraulic cylinder 150 is disposed in the accommodating space 110 b , and the other end thereof penetrates the accommodating space 110 b and extends into the testing cavity 110 a to abut against the fixing plate 145 , so as to apply pressure to the testing bearing 120 .

[0100] In at least one embodiment of the present application, the hydraulic cylinder 150 is provided with a connecting hole 150 a , and the connecting hole 150 a is connected to an external hydraulic station.

[0101] In this embodiment, the external hydraulic station supplies hydraulic oil to the hydraulic cylinder 150 through the connection hole 150 a to adjust the internal pressure of the hydraulic cylinder 150 .

[0102] The push rod of the hydraulic cylinder 150 pushes the fixed plate 145 to apply a predetermined pressure to the test bearing 120. This pressure can simulate different load conditions in actual applications and test the performance of the lubricating grease.

[0103] Under the applied pressure, the test equipment is started to test the lubricating grease, including friction coefficient, wear rate, etc.

[0104] After the test is completed, data is collected and analyzed to analyze the performance of the lubricant under different pressure conditions.

[0105] The hydraulic cylinder 150 provides a controllable pressure application means, so that the test bench can simulate different pressure conditions that may be encountered in actual use.

[0106] The combination of the hydraulic cylinder 150 and the hydraulic station allows for precise control of the pressure applied to the test bearing 120 , thereby testing the performance of the lubricating grease at different pressures.

[0107] By precisely controlling the pressure, the test bench can provide more stable and repeatable test conditions, reduce the impact of external factors on test results, and improve data reliability and accuracy.

[0108] By testing the performance of lubricants under different pressure conditions, users can better select lubricants suitable for specific working conditions and improve the performance and life of equipment.

[0109] The accommodating space 110b is an open space.

[0110] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
