Description

Technical Field

[0001] This invention relates to the field of lubricating grease testing equipment, and in particular to a lubricating grease corrosion resistance testing machine. Background Technology

[0002] The corrosion resistance of grease refers to its ability to prevent the metal in contact with it from being corroded. The thickener and base oil of grease themselves do not corrode metals. There are many reasons why grease becomes corrosive, mainly due to the production of acidic substances by oxidation. Generally speaking, excessive free organic acids and alkalis can cause corrosion. Therefore, a grease corrosion resistance tester is needed to test the corrosion resistance of grease.

[0003] A search revealed a grease corrosion resistance testing machine in invention patent CN116337742B, comprising a test housing, clamping components, water sprayers, and a large air cylinder. The test housing has threaded clamping components on both sides. Two water sprayers are located on each of the left and right sides of the upper part of the test housing. A large air cylinder is located at the top of the test housing. By incorporating a grease-adding ring, grease is intermittently replenished to the inner wall of the ball bearing during testing. In conjunction with an applicator, grease is automatically and evenly applied to the inner wall of the ball bearing during testing, preventing uneven application due to grease slipping from the inner wall and affecting the test results. Test results; however, this method has the following problems in actual use: During the rotation of the ball bearing, due to the influence of centrifugal force, this injection method will cause the grease on the outer surface of the inner ring of the ball bearing to be thrown outward, making it difficult to form a uniform diffusion phenomenon. Moreover, this application method cannot achieve a good uniform layer of grease on the outer side of the inner ring. At the same time, the above solution has the effect of grease recycling, but it is not convenient to collect the grease applied to the ball bearing for the grease thrown out during the operation. As a result, after the grease has been in contact with the ball bearing, when the user picks up and tests the ball bearing, the grease on the ball bearing will increase the difficulty of the operation.

[0004] Based on this, the present invention proposes a grease corrosion resistance testing machine to solve the problems existing in the prior art. Summary of the Invention

[0005] In view of this, the main objective of the present invention is to provide a grease corrosion resistance testing machine to solve the problems of poor uniformity of grease during testing and difficulty in collecting grease from ball bearings, which increases the difficulty of the work, in traditional grease corrosion resistance testing machines.

The arc-shaped sponge is mounted on the retaining ring, and one end of the strip-shaped sponge passes through the flow guide ring and is connected to the flow guide ring.

[0013] The equalization mechanism is symmetrically arranged between two retaining rings, including two equalization rings respectively located on the upper and lower sides of the guide ring. The inner side of the equalization ring is provided with an annular guide groove and a strip guide groove that are connected to each other.

[0014] In a preferred embodiment, the equalizing ring is funnel-shaped, with the flared end of the equalizing ring located away from the guide ring.

[0015] In a preferred embodiment, two cover plates are hinged inside the strip-shaped guide channel, and the opposite sides of the two cover plates are arranged at an angle.

[0016] In a preferred embodiment, a first spring is provided between the cover plate and the strip-shaped guide channel, a piston strip is slidably connected inside the adjusting ring, a pull rope is fixedly connected to one side of the piston strip and the outside of the cover plate, two through holes are opened inside the strip-shaped guide channel, a circular plate is hinged in the through hole, and a second spring is provided between one side of the circular plate and the through hole.

[0017] In a preferred embodiment, an electric push rod is provided on the outer side of the retaining ring, a piston plate is provided at one end of the electric push rod, a collection tube is provided on the outer side of the electric push rod and located outside the retaining ring, two collection boxes are provided on the outer side of the collection tube, the collection boxes are located outside the adjusting ring and communicate with the through hole, and a T-shaped pipe is threadedly connected to the collection tube, one end of the T-shaped pipe is connected to the collection box.

[0018] In a preferred embodiment, a material guiding channel is formed between the strip-shaped guide channel, the annular guide channel, and the cover plate.

[0019] In a preferred embodiment, the injection mechanism further includes an electric grease nipple, the output end of which is connected to two conduits, one end of which extends into an arc-shaped sponge and a strip-shaped sponge, respectively. An installation box is fitted on the outer side of both the arc-shaped sponge and the strip-shaped sponge, and the two installation boxes are fixedly connected on opposite sides. The outer installation box is embedded in a retaining ring.

[0020] In a preferred embodiment, the driving component includes a speed-regulating motor, a connecting plate, and a set of anti-slip rods evenly distributed on the connecting plate. The speed-regulating motor is disposed on the inner bottom wall of the housing, and the output shaft of the speed-regulating motor is connected to the connecting plate via a coupling. A hydraulic rod fixedly connected to the anti-slip rods is disposed inside the connecting plate.

[0021] In a preferred embodiment, the support further includes two electric lifting rods, which are disposed within the bottom retaining ring and whose top ends are connected to the top retaining ring. The bottom retaining ring is fixed to the housing by a positioning column.

[0022] In a preferred embodiment, a riser is provided inside the housing, a heating wire is provided inside the riser, a set of discharge holes are provided on the outside of the riser, a horizontal tube is provided on the outside of the riser extending into the bottom retaining ring, a metal ring is provided in the bottom retaining ring, one end of the metal ring extends into the top retaining ring, and one end of the horizontal tube is close to the metal ring.

[0023] Compared with the prior art, the present invention provides a grease corrosion resistance testing machine, which has the following beneficial effects:

[0024] 1. Through the structural design of this grease corrosion resistance testing machine, during use, grease is injected into the balls and inner ring of the ball bearing through arc-shaped and strip-shaped sponges respectively. The polytetrafluoroethylene arc-shaped sponge is used to inject grease evenly on the outside of the balls while injecting it, and the grease discharged by the strip-shaped sponge will accumulate on the inner ring, so that the grease is between the guide ring and the inner ring. After rotation, under the influence of centrifugal force, the grease will diffuse outward along the guide ring. At this time, the grease will move along the trumpet-shaped equalization ring. The strip-shaped guide groove facilitates the movement of the grease in the up and down outward direction, and the annular guide groove facilitates the diffusion of the grease outward. During the continuous injection of grease and the movement of the inner ring, the grease accumulated on the inner ring will also be thrown off to different areas on the equalization ring during its rotation. Finally, the gap between the guide ring, the equalization ring and the inner ring will be filled, thereby forming a grease layer of a certain thickness, so that the injection achieves a uniform dispersion effect.

[0025] 2. Through the setting of the equalization mechanism, after the ball bearing comes into contact with the grease and after the preset operation time, the electric push rod can be activated, which, together with the piston plate, creates negative pressure in the collection box. At this time, the piston strip will drive the cover plate to move along the hinge axis. After the cover plate moves, it itself forms a scraper, which can scrape off the grease on the inner ring. After the cover plate moves, the through hole on the equalization ring is exposed. After the inner round cover is opened by the negative pressure, the grease scraped off by the cover plate can be collected and extracted, reducing the excessive grease residue on the inner ring of the ball bearing. This makes it easier for the testing personnel to pick up and observe the ball bearing, reducing the difficulty of picking up and testing the ball bearing. It solves the problems of poor uniformity of grease testing and difficulty in collecting grease on the ball bearing that exist in traditional grease corrosion resistance testing machines.

[0049] The following is in conjunction with the instruction manual appendix. Figures 1-11 The present invention describes a grease corrosion resistance testing machine.

[0050] Example 1:

[0051] like Figure 1 , Figure 2 , Figure 7 , Figure 9 and Figure 11 As shown, in one embodiment, a grease corrosion resistance testing machine includes a housing 100, and a drive component 200, a support component 300, an injection mechanism 400, and a mixing mechanism 500 disposed inside the housing 100; wherein:

[0052] The housing 100 is a test machine shell with an internal mounting cavity, used to fix and protect the drive component 200, support component 300, injection mechanism 400 and mixing mechanism 500;

[0053] The drive component 200 is installed inside the support component 300 inside the housing 100;

[0054] The support member 300 is fixedly installed inside the housing 100 by a positioning column, and includes two symmetrically arranged retaining rings 310.

[0055] The injection mechanism 400 is provided with four parts and is installed on the retaining ring 310. It includes an arc-shaped sponge 410, a strip-shaped sponge 420 and a guide ring 430. The arc-shaped sponge 410 is installed on the retaining ring 310, and one end of the strip-shaped sponge 420 passes through the guide ring 430 and is fixedly connected to the guide ring 430.

[0056] There are two equalizing mechanisms 500, which are symmetrically installed between two retaining rings 310. The equalizing mechanism includes two equalizing rings 510 that are fixedly installed on the upper and lower sides of the guide ring 430 respectively. Two annular guide grooves 511 are opened on the inner side of the equalizing ring 510, and two strip guide grooves 512 that communicate with the annular guide grooves 511 are opened on the inner side of the equalizing ring 510.

[0057] like Figure 4 and Figure 5 As shown, the equalizing ring 510 has a trumpet-shaped structure, and the flared end of the equalizing ring 510 is far away from the guide ring 430.

[0058] It should be noted that, in this embodiment, by adopting the aforementioned trumpet-shaped equalizing ring 510, the grease accumulated between the guide ring 430 and the inner ring can be thrown outward by centrifugal force during the rotation of the inner ring. Combined with the shape of the inner side of the equalizing ring 510, the grease diffuses to the upper and lower sides of the guide ring 430. During this upward and downward diffusion, some grease is squeezed into the corresponding annular guide groove 511, completing the lateral diffusion. Simultaneously, during the rotation of the inner ring, the grease on its outer side can be dropped onto the equalizing ring 510. The area is designed to accelerate the formation of the grease layer. Simultaneously, as the strip-shaped sponge 420 continuously introduces grease, the continuously rotating inner ring further diffuses the grease, ultimately filling the gaps between the guide ring 430, the equalizing ring 510, and the inner ring. This results in a grease layer of a certain thickness, achieving a stable and uniform grease injection effect. Furthermore, the arc-shaped sponge 410 can individually inject grease into the balls, using a wrapping and spreading method to complete the comprehensive grease coating process during the continuous rotation of the balls, ensuring uniformity.

[0059] As a preferred embodiment, such as Figure 6 , Figure 9 and Figure 11 As shown, the strip-shaped guide channel 512 has two cover plates 513 hinged inside, and the opposite sides of the two cover plates 513 are set at an angle.

[0060] Specifically, in this embodiment, by using the bend on the cover plate 513, the grease can be guided to move into the corresponding annular guide groove 511, so as to ensure the diffusion effect of the grease.

[0061] As a preferred embodiment, such as Figure 9 and Figure 11 As shown, a first spring 514 is installed between the cover plate 513 and the strip-shaped guide channel 512. A piston strip 517 is slidably connected inside the adjusting ring 510. A pull rope 518 is fixedly connected to the outside of the cover plate 513 on one side of the piston strip 517. Two through holes are opened inside the strip-shaped guide channel 512. A circular plate 515 is hinged inside the through holes. A second spring 516 is installed between one side of the circular plate 515 and the through hole.

[0062] Specifically, in this embodiment, with the above-described structure, before the ball bearing needs to be removed for inspection, the piston strip 517 can be driven to move, causing it to pull the rope 518 and pull the cover plate 513, so that the side of the cover plate 513 moves to the outside of the inner ring, thereby scraping the grease layer on the inner ring and guiding the grease along the cover plate 513 into the strip-shaped guide groove 512. Then, the negative pressure in the three-way pipe is used to cause the circular plate 515 to hinge, so that the scraped grease is guided into the collection box 314 along the through hole.

[0063] Example 2:

[0064] Unlike Embodiment 1 described above, as Figure 2 and Figure 6 As shown, the injection mechanism 400 also includes an electric grease nipple 440. The output end of the electric grease nipple 440 is connected to two conduits. One end of each conduit extends into the interior of the arc-shaped sponge 410 and the strip-shaped sponge 420, respectively. Mounting boxes are fitted on the outer sides of both the arc-shaped sponge 410 and the strip-shaped sponge 420. The two mounting boxes are fixedly connected on opposite sides, and the outer mounting boxes are embedded in the retaining ring 310.

[0065] It should be noted that, in this embodiment, with the above-described structure, when grease needs to be introduced, the feed pipe on the electric grease nipple 440 can be connected to the grease pipe, and then the machine can be started to inject the grease into the interior of the arc-shaped sponge 410 and the strip-shaped sponge 420 along the corresponding conduits.

[0066] As a preferred embodiment, such as Figure 2 , Figure 3 and Figure 6As shown, an electric push rod 311 is provided on the outer side of the retaining ring 310. A piston plate 312 is installed at one end of the electric push rod 311. A collection tube 313 located outside the retaining ring 310 is installed on the outer side of the electric push rod 311. Two collection boxes 314 are provided on the outer side of the collection tube 313. The collection boxes 314 are located outside the adjusting ring 510 and communicate with the through hole. A three-way pipe is threaded onto the collection tube 313. One end of the three-way pipe communicates with the collection box 314.

[0067] Specifically, in this embodiment, by activating the electric push rod 311, the piston plate 312 is driven to move inside the collection pipe 313. At this time, the three-way pipe on the collection pipe 313 will perform a suction operation, thereby creating a negative pressure inside the collection box 314, which, together with the round hole, performs a grease recovery operation.

[0068] Example 3:

[0069] Unlike the embodiments described above, as Figure 2 As shown, the driving component 200 includes a speed-regulating motor 210, a connecting plate 230, and a set of anti-slip rods 220 evenly distributed on the connecting plate 230. The speed-regulating motor 210 is installed on the inner bottom wall of the housing 100. The output shaft of the speed-regulating motor 210 is fixedly connected to the connecting plate 230 through a coupling. A set of hydraulic rods fixedly connected to the anti-slip rods 220 is provided inside the connecting plate 230.

[0070] It should be noted that, in this embodiment, with the above-described structure, after the ball bearing is placed, the hydraulic rod can be activated to drive the anti-slip rod 220 to move outward until it is in close contact with the inner wall of the inner ring of the ball bearing. Then, the speed-regulating motor 210 is activated, and different speeds are selected according to the test requirements to drive the ball bearing after the grease has been injected to move.

[0071] Example 4:

[0072] Unlike the embodiments described above, as Figure 2 and Figure 7 As shown, the support member 300 also includes two electric lifting rods 320. The electric lifting rods 320 are installed inside the bottom retaining ring 310, and the top end of the electric lifting rods 320 is fixedly connected to the top retaining ring 310. The bottom retaining ring 310 is fixedly installed inside the housing 100.

[0073] It should be noted that, in this embodiment, with the above-described structure, the electric lifting rod 320 can be activated before testing, causing the top retaining ring 310 to move upward, thus facilitating the user to place the ball bearing. The same steps are also used when removing it later, making it convenient for the user to remove and place the ball bearing.

[0074] Example 5:

[0075] Unlike the embodiments described above, as Figure 1 , Figure 2 and Figure 3 As shown, a riser 110 is installed inside the housing 100. An electric heating wire is installed inside the riser 110, and a set of discharge holes are opened on the outside of the riser 110. A horizontal tube 130 extending into the bottom retaining ring 310 is installed on the outside of the riser 110. A metal ring 315 is fixedly installed inside the bottom retaining ring 310. One end of the metal ring 315 extends into the inside of the top retaining ring 310, and one end of the horizontal tube 130 is close to the metal ring 315.

[0076] It should be noted that in this embodiment, the operator can use an electric heating wire and use a microcontroller and PID controller to regulate the temperature of the heating wire; the heat energy in the riser 110 is introduced into the chamber 100 through the discharge hole to complete the test of the corrosion resistance of the lubricating grease under different temperature environments.

[0077] Meanwhile, after the normal temperature control test is completed, the staff can place a new ball bearing, open the valve on the horizontal tube 130, and let the heat source be directly introduced into the metal ring 315. The metal ring 315, which is in contact with the outer ring of the ball bearing, can quickly raise the temperature of the ball bearing, thereby simulating the instantaneous high temperature of the engine and the overload of the electromechanical equipment, so as to test the corrosiveness of the grease under short-term high temperature.

[0078] As a preferred embodiment, such as Figure 4 , Figure 8 and Figure 9 As shown, material guiding channels are formed between the strip-shaped guide channel 512, the annular guide channel 511 and the cover plate 513, and the arc-shaped sponge 410 and the strip-shaped sponge 420 are both made of polytetrafluoroethylene sponge.

[0079] Specifically, in this embodiment, with the above-described structure, when too much grease is injected, a grease layer of a certain thickness is formed between the guide ring 430, the equalizing ring 510, and the inner ring. The excess grease can move along the guide channel to the space between the cover plate 513 and the circular plate 515. Subsequently, when too much grease is introduced, it moves along the through hole and squeezes the circular plate 515, so that the excess grease is placed inside the through hole and introduced into the collection box 314. This achieves an anti-overflow effect during the grease equalization process, reducing the phenomenon of grease being randomly thrown out and accumulating on the side of the ball bearing.

[0080] The working principle and usage process of the grease corrosion resistance testing machine of the present invention include: Before testing, the electric lifting rod 320 can be activated, causing the top retaining ring 310 to move upward, thus facilitating the placement of the ball bearing by the user. Then, the two retaining rings 310 are joined together to limit the ball bearing, securing the outer ring while allowing the inner ring to move normally. Next, a speed-regulating motor 210 drives the inner ring to rotate. During rotation, the electric grease fitting 440 is activated, injecting grease along the corresponding conduit into the interior of the arc-shaped sponge 410 and the strip-shaped sponge 420. At this time, some grease is on the outside of the ball bearing, and some grease is between the guide ring 430 and the inner ring. During the rotation of the inner ring, centrifugal force causes the grease to be thrown outward, which, combined with the shape of the inner side of the equalizing ring 510, creates a smoothing effect. The grease is longitudinally diffused on both sides of the guide ring 430. During the longitudinal diffusion process, some grease is squeezed into the corresponding annular guide groove 511 to complete the lateral diffusion. At the same time, during the rotation of the inner ring, the grease on its outer side can be dropped onto different areas of the equalization ring 510, which increases the speed of grease layer formation. After the strip sponge 420 continuously introduces grease, the grease is continuously diffused in conjunction with the continuously rotating inner ring. Finally, the gap between the guide ring 430, the equalization ring 510 and the inner ring will be filled, thereby forming a grease layer of a certain thickness, achieving a stable and uniform grease injection effect. At the same time, the arc sponge 410 can inject grease into the ball individually. By wrapping and spreading the grease, the ball can complete the comprehensive grease coating operation during continuous rotation, ensuring uniformity.

[0081] Furthermore, if excessive grease is injected during the grease injection process, the excess grease can move along the guide channel to between the cover plate 513 and the round plate 515. Subsequently, after too much grease has been injected, it moves along the through hole and squeezes the round plate 515, so that the excess grease is placed inside the through hole and introduced into the collection box 314. This has the effect of preventing overflow during the grease mixing process and reduces the occurrence of grease being thrown out randomly and accumulating on the side of the ball bearing.

[0082] When the ball bearing needs to be removed for inspection, the pull rope 518 pulls the cover plate 513, causing the side of the cover plate 513 to move outward from the inner ring, thereby scraping the grease layer on the inner ring and guiding the grease along the cover plate 513 into the strip guide groove 512. Then, the negative pressure in the three-way pipe causes the circular plate 515 to hinge, guiding the scraped grease along the through hole into the collection box 314. This reduces the occurrence of excessive grease residue on the inner ring, making it easier for staff to handle and inspect the bearing. At the same time, it can achieve the effect of grease recycling and is more energy-efficient.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
