Description

Technical Field

[0001] This disclosure relates to the field of fine chemical testing equipment technology, and in particular to a lubricating grease torque testing device. Background Technology

[0002] The grease torque test device is specifically designed to evaluate the performance of grease under low-temperature conditions. According to the preparation requirements of the current People's Republic of China Petroleum and Chemical Industry Standard SH / T 0338-92 (2004), there is still a possibility of human error in actual operation. Firstly, the total mass of the bearing housing reaches 454g ± 3g. The standard requires that when the test bearing and bearing housing of this weight are installed and fixed on the test shaft, the test bearing should not be rotated. For people with insufficient strength, the risk of the test bearing rotating during installation is relatively high. Furthermore, the experiment requires the force-measuring rope to be hung on the hook on the outer ring of the bearing housing, and the rope needs to be adjusted until it is nearly taut, but the rope length is basically fixed. This means that when the bearing housing is installed on the test shaft, the hook position must be accurately placed; otherwise, it cannot be guaranteed that the test bearing will not rotate. The influence of these factors means that during manual operation, it is impossible to ensure that the bearing housing is completely fixed, thus compromising the accuracy of the experimental preparation process.

[0050] Typical embodiments embodying the features and advantages of this disclosure will be described in detail in the following description. It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

[0051] In the following description of various exemplary embodiments of this disclosure, reference is made to the accompanying drawings, which form part of this disclosure, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this disclosure. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this disclosure. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this disclosure, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this disclosure.

[0052] See Figure 1The diagram illustrates, in a representative manner, the structural schematic of the grease torque testing device proposed in this disclosure. In this exemplary embodiment, the grease torque testing device is described using an example of torque testing of grease in a low-temperature environment. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below to apply the relevant designs of this disclosure to torque testing of grease in other environments; these changes remain within the scope of the principles of the grease torque testing device proposed in this disclosure.

[0053] like Figure 1 As shown, in one embodiment of this disclosure, the lubricating grease torque testing device includes a test chamber 100, a bearing housing 200, a lifting device 300, a force measuring rope 400, and a rotating motor 500. (See also...) Figures 2 to 4 , Figure 2 A three-dimensional schematic diagram of the lifting device 300 is shown in the figure. Figure 3 The diagram shows a representative three-dimensional view of the rotary motor 500, the worktable 600, and the translation mechanism 700. Figure 4 China representatively shows Figure 3 The following is a side view of the grease torque testing device proposed in this disclosure. The structure, connection method, and functional relationship of the main components will be described in detail below with reference to the above-mentioned figures.

[0054] like Figure 1 and Figure 2As shown, in one embodiment of this disclosure, the bearing housing 200 is located inside the test chamber 100, and the bearing housing 200 is connected to a secondary shaft 210. The secondary shaft 210 can extend horizontally, that is, the axial direction of the secondary shaft 210 is horizontal, specifically the first horizontal direction shown in the figures (e.g., referring to direction D1 shown in the figures). The lifting device 300 is placed inside the test chamber 100, and the lifting device 300 is used to lift and support the bearing housing 200. The force measuring rope 400 is disposed inside the test chamber 100, the upper end of the force measuring rope 400 is connected to the top wall of the test chamber 100, and the lower end of the force measuring rope 400 is used to connect to the bearing housing 200. The rotating motor 500 is located outside the test chamber 100, and the rotating motor 500 is connected to a main shaft 510. The main shaft 510 can extend horizontally, that is, the axial direction of the main shaft 510 is horizontal, specifically the first horizontal direction shown in the figures. The main shaft 510 is partially inserted into the test housing 100 and is detachably connected to the secondary shaft 210. The rotating motor 500 drives the bearing housing 200 via the connected main shaft 510 and secondary shaft 210. Through the above structural design, this disclosure utilizes the lifting device 300 to support the bearing seat 200. Since the lifting device 300 is placed in the test chamber 100 and has no fixed connection with the test chamber 100, that is, the lifting device 300 is arranged in the test chamber 100 in a non-fixed manner. During the preparation work before the test, the lifting device 300 can be placed directly below the force measuring rope 400 and the bearing seat 200 can be placed. Accordingly, by utilizing the non-fixed arrangement of the lifting device 300 and the lifting of the bearing seat 200, this disclosure can conveniently connect the force measuring rope 400 to the bearing seat 200 (for example, conveniently hook the loop of the force measuring rope 400 onto the hook of the bearing seat 200) and adjust its position, without worrying about the bearing (e.g., ball bearing) of the bearing seat 200 rotating, making the test device more portable. In addition, after the preparation work is completed, lowering and removing the lifting device 300 can also ensure that the test can proceed normally.

[0055] In one embodiment of this disclosure, the test chamber 100 can be a low-temperature chamber, which can provide the low-temperature environment required for testing inside itself, thereby realizing the torque test of the lubricating grease under low-temperature conditions.

[0056] like Figure 1 and Figure 2 As shown, in one embodiment of this disclosure, the lifting device 300 may include a first base 310, a platform 320, and a lifting mechanism. The first base 310 is placed on the bottom wall of the test chamber 100. The platform 320 is located above the first base 310 and is used to support the bearing seat 200. The lifting mechanism is connected between the first base 310 and the platform 320, and is used to drive the platform 320 to move up and down relative to the first base 310. The lifting mechanism is a forklift type lift 330.

[0057] like Figure 2 As shown, based on the structural design of the lifting device 300 including a lifting mechanism and the lifting mechanism being a forklift type lift 330, in one embodiment of this disclosure, the forklift type lift 330 may include at least two forklift assemblies 331 connected vertically, such as the two forklift assemblies 331 shown in the figure. Specifically, each forklift assembly 331 includes two forklift units 3311 spaced apart in a first horizontal direction. Each forklift unit 3311 includes two forklifts 33111, the middle parts of the two forklifts 33111 are rotatably connected, the upper ends of the two forklifts 33111 are respectively rotatably connected to the platform 320 or the lower end of the forklift 33111 of the adjacent forklift assembly 331, and the lower ends of the two forklifts 33111 are respectively rotatably connected to the first base 310 or the upper end of the forklift 33111 of the adjacent forklift assembly 331. Based on this, the forklift 330 can be provided with at least one pair of crossbars 332, which extend along a first horizontal direction. The two crossbars 332 in the same pair are arranged at intervals along a second horizontal direction perpendicular to the first horizontal direction (e.g., the D2 direction shown in the attached figure). The crossbars 332 are connected to the rotational connection of two adjacent forklift assemblies 331. It should be noted that when the axial direction of the main shaft 510 is horizontal, the aforementioned first horizontal direction can be a horizontal direction parallel to the axial direction, a horizontal direction perpendicular to the axial direction, or a horizontal direction with a certain angle (greater than 0 and less than 90°) with the axial direction. In other words, the arrangement of the forklift assemblies 331 can be arranged by rotating a certain angle in the horizontal direction, and is not limited to the arrangement shown in the attached figure. Through the above structural design, at least two forklift assemblies 331 enable the forklift 330 to have a larger lifting adjustment range, meeting a wider range of testing and adjustment needs. At the same time, this disclosure uses the crossbars 332 to strengthen the structural strength of the forklift 330, improving the load-bearing capacity of the lifting device 300 and the stability during the lifting adjustment process. In other embodiments of this disclosure, the forklift 330 may also include only one forklift assembly 331, and is not limited to this embodiment.

[0058] like Figure 2As shown, based on the structural design of the forklift lift 330 with crossbars 332, in one embodiment of this disclosure, the forklift lift 330 may be equipped with an adjusting screw 333. The adjusting screw 333 extends along a second horizontal direction and passes through two pairs of crossbars 332. One end of the adjusting screw 333 is equipped with an adjusting knob 3331. The lifting device 300 drives the adjusting screw 333 to rotate by the user turning the adjusting knob 3331, thereby adjusting the distance between the two pairs of crossbars 332 and thus adjusting the lifting posture of the forklift lift 330. Through the above structural design, this disclosure can utilize the crossbars 332 to arrange the adjusting screw 333 to achieve the lifting adjustment of the forklift lift 330, which is simple in structure and convenient in operation. In other embodiments of this disclosure, one end of the adjusting screw 333 may also be equipped with a lifting motor, which drives the adjusting screw 333 to rotate, and this is not limited to this embodiment.

[0059] like Figure 2 As shown, based on the structural design of the lifting device 300 including the platform 320, in one embodiment of this disclosure, the platform 320 may be provided with positioning holes. These positioning holes match the shape of a portion of the edge structure of the bearing housing 200. When the bearing housing 200 is supported on the platform 320, the portion of the edge structure of the bearing housing 200 is accommodated in the positioning holes, thereby positioning the bearing housing 200 on the platform 320. Specifically, according to the shape differences of the portion structures of different sides (e.g., both sides in the first horizontal direction) of the bearing housing 200, the platform 320 may be arranged with positioning holes of different shapes or numbers correspondingly. For example... Figure 2 The structure shown has two spaced-apart first positioning holes 321 on one side of the platform 320 in the first horizontal direction, and a second positioning hole 322 on the other side of the platform 320 in the first horizontal direction. Through this structural design, the present disclosure can achieve the positioning of the bearing housing 200 by utilizing the cooperation between the positioning holes and a portion of the edge structure of the bearing housing 200, for example, positioning the bearing housing 200 in the lateral direction (e.g., the second horizontal direction). This helps to maintain consistency between the lateral position of the bearing housing 200 and the force-measuring rope 400, making the lifting device 300's support and lifting of the bearing housing 200 more stable and reliable.

[0060] In one embodiment of this disclosure, the bearing housing 200 may be provided with a hook (not shown in the figure), and correspondingly, the lower end of the force measuring rope 400 may be provided with a collar (not shown in the figure), which is used to hook the hook.

[0061] like Figure 1As shown, in one embodiment of this disclosure, the main shaft 510 and the secondary shaft 210 can be detachably connected via a coupling 511. Specifically, the coupling 511 may have screws that can secure the coupling 511 to the main shaft 510 and the secondary shaft 210 when they are connected via the coupling 511. For example, the coupling 511 may be pre-installed at the end of the main shaft 510 located inside the test housing 100.

[0062] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of this disclosure, the grease torque testing device may further include a worktable 600 and a translation mechanism 700. The worktable 600 is located outside the test chamber 100, and a rotary motor 500 is mounted on the worktable 600. The translation mechanism 700 is located outside the test chamber 100 and is used to drive the worktable 600 to move axially along the main shaft 510 (e.g., in the first horizontal direction shown in the figures). Accordingly, the grease torque testing device moves the rotary motor 500 axially by moving the worktable 600, thereby achieving relative movement between the main shaft 510 and the secondary shaft 210. Through the above structural design, this disclosure enables the axial movement of the rotary motor 500 connected to the main shaft 510, avoiding the problem of instability caused by insufficient manpower during the installation of the bearing housing 200, which could lead to bearing rotation during installation. Based on this, and in conjunction with the lifting adjustment function and non-fixed arrangement of the aforementioned lifting device 300, this disclosure can effectively avoid experimental errors and inaccuracies caused by human factors in the test preparation stage. Therefore, this disclosure can further mechanize and automate the operation of the lubricating grease torque testing device, reduce human error to a greater extent, and enhance the portability and accuracy of the testing device.

[0063] like Figure 3 and Figure 4As shown, based on the structural design of the grease torque testing device including a translation mechanism 700, in one embodiment of this disclosure, the worktable 600 may be provided with a threaded hole extending axially. The translation mechanism 700 may include a second base 710, a ball screw shaft 720, and a translation motor 730. The ball screw shaft 720 extends axially (e.g., in the first horizontal direction shown in the figure), and both ends of the ball screw shaft 720 are respectively mounted on the second base 710 via screw seats 721, with the ball screw shaft 720 passing through the threaded hole. The translation motor 730 is connected to the ball screw shaft 720 and is used to drive the ball screw shaft 720 to rotate, thereby driving the worktable 600 to move the rotary motor 500 axially. Through the above structural design, by using the ball screw shaft 720 to achieve the translational drive of the worktable 600, this disclosure can achieve more precise and sensitive axial displacement adjustment of the rotary motor 500, further improving the accuracy of the testing device.

[0064] like Figure 3 and Figure 4 As shown, based on the structural design of the translation mechanism 700, which includes a second base 710 and a ball screw shaft 720, in one embodiment of this disclosure, the worktable 600 may be provided with a guide hole extending axially. The translation mechanism 700 may also include a guide rod 740. The guide rod 740 extends axially (e.g., in the first horizontal direction shown in the figure), and both ends of the guide rod 740 are respectively disposed on the second base 710 via guide rod seats 741, with the guide rod 740 passing through the guide hole. Through the above structural design, this disclosure can utilize the cooperation between the guide rod 740 and the guide hole to realize the guiding function of the worktable 600 and the translation motor 730 during axial movement, further improving stability and reliability.

[0065] like Figure 3 As shown, based on the structural design of the worktable 600 having guide holes and the translation mechanism 700 including guide rods 740, in one embodiment of this disclosure, the worktable 600 may have two guide holes, which are spaced apart along a second horizontal direction, and the two guide holes may further be located on both sides of the wire hole in the second horizontal direction. Correspondingly, the translation mechanism 700 may include two guide rods 740, which pass through the two guide holes respectively. Through the above structural design, this disclosure can further improve stability and reliability.

[0066] Based on the structural design of the translation mechanism 700 including the worktable 600, in one embodiment of this disclosure, the worktable 600 may be provided with a slider. The slider may be an integral structure with the worktable 600, or it may be a separate component fixedly connected to the worktable 600. The slider is located at the bottom of the worktable 600, and the aforementioned wire holes and guide holes may be formed in the slider.

[0067] Based on the structural design of the translation mechanism 700 including the translation motor 730, in one embodiment of this disclosure, the translation motor 730 can be a stepper motor.

[0068] Based on the above, the working process of the lubricating grease torque testing device proposed in this disclosure is roughly as follows:

[0069] In use, first place the bearing housing 200 with ball bearings on the platform 320 with the height adjusted. The rotation angle of the bearing housing 200 can be freely adjusted to achieve near-tightening with the force measuring rope 400. This operation effectively avoids the problem of bearing housing 200 rotating during the adjustment of the force measuring rope 400 after the auxiliary shaft 210 is connected to the main shaft 510. After the relative positions of the bearing housing 200 and the force measuring rope 400 are adjusted, the ball screw shaft 720 can be moved by starting the translation motor 730, causing the worktable 600 to translate axially. This drives the rotary motor 500 to move towards the test chamber 100, which in turn causes the main shaft 510 to move towards the auxiliary shaft 210. Finally, the main shaft 510 connected to the coupling 511 finds the auxiliary shaft 210 of the bearing housing 200 and the main shaft 510 and auxiliary shaft 210 are connected via the coupling 511. This effectively avoids the problem of unstable installation position caused by insufficient manual strength. After the main shaft 510 and the secondary shaft 210 are connected by the coupling 511, the lifting device 300 can be adjusted to lower the platform 320 and disengage it from the bearing seat 200. The bearing seat 200 will then be suspended in the air. At this time, the bearing seat 200 is fully supported on the secondary shaft 210 (and is suspended by the force measuring rope 400). Based on this, subsequent testing work can be carried out.

[0070] It should be noted that the grease torque testing apparatus shown in the accompanying drawings and described in this specification is merely a few examples among many testing apparatuses capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the grease torque testing apparatus shown in the accompanying drawings or described in this specification.

[0071] In summary, the grease torque testing device proposed in this disclosure includes a test chamber 100, a bearing housing 200, a lifting device 300, a force measuring rope 400, and a rotating motor 500. The lifting device 300 is placed inside the test chamber 100 and is used to lift and support the bearing housing 200. The upper end of the force measuring rope 400 is connected to the top wall of the test chamber 100, and the lower end of the force measuring rope 400 is used to connect to the bearing housing 200. The rotating motor 500 is located outside the test chamber 100 and is connected to a main shaft 510. The main shaft 510 is partially inserted inside the test chamber 100 and is detachably connected to the secondary shaft 210 of the bearing housing 200. Through the above structural design, this disclosure utilizes the lifting device 300 to support the bearing seat 200. Since the lifting device 300 is placed in the test chamber 100 and has no fixed connection with the test chamber 100, that is, the lifting device 300 is arranged in the test chamber 100 in a non-fixed manner. During the preparation work before the test, the lifting device 300 can be placed directly below the force measuring rope 400 and the bearing seat 200 can be placed. Accordingly, by utilizing the non-fixed arrangement of the lifting device 300 and the lifting of the bearing seat 200, this disclosure can conveniently connect the force measuring rope 400 to the bearing seat 200 and adjust its position without considering the influence of the bearing rotation of the bearing seat 200 on the test accuracy, making the test device more portable.
