Description

Technical Field

[0001] This utility model relates to the technical field of gear wear testing equipment, specifically a gear wear testing machine. Background Technology

[0002] The method for determining the wear resistance of grease in gear transmission, with standard number SH / T0427, can be used to determine the wear resistance of grease in gear transmission. The test equipment only needs to be tested for quality loss or similar parameters after running under specified conditions for a period of time. However, the test time and required load vary for different products. Currently, conventional equipment, for the sake of versatility, generally does not have many options and the load is fixed, making it difficult to change. Utility Model Content

[0003] To address the problem of difficulty in changing the load in conventional testing equipment, this invention provides a gear wear testing machine.

[0004] The technical solution of this utility model is as follows:

[0005] A gear wear testing machine includes a test body disposed at the center of a support, the test body including a turntable driven by a drive body, and the rotation plane of the turntable is a vertical plane;

[0006] The bracket has first guide rods symmetrically arranged at both ends of the turntable, and the rotation axis of the first guide rods is parallel to the rotation axis of the turntable.

[0007] The first guide rod is also rotatably connected to a second guide rod, and the rotation axis of the second guide rod is set horizontally and perpendicular to the first guide rod;

[0008] The end of the second guide rod extends beyond the upper surface of the bracket;

[0009] The turntable is equipped with a main body for holding objects, and hanging ropes are provided at both ends of the main body for holding objects. The other end of the hanging rope passes through the first guide rod and the second guide rod in sequence and is connected to the counterweight.

[0010] The test parameters can be changed simply by replacing the counterweight as needed, and the presence of the aforementioned guide rod makes it easy to place the counterweight in a position that is convenient for replacement.

[0011] To prevent the counterweight from falling, protective shells are installed at both ends of the bracket along the counterweight's movement path. These protective shells support the counterweight and are positioned above the ground at their lower ends. The protective shells protect the counterweight from accidental drops.

[0012] As a preferred embodiment, the turntable is provided with multiple test holes for the main body of the installed object, and the distance between the multiple test holes and the center of the turntable is different. By changing the test holes, the test parameters can be changed.

[0013] To protect the operators, an isolation shell is provided on the outside of the turntable.

[0014] To facilitate testing and protect operators, the turntable is equipped with a sliding door that can be opened and closed at its front end.

[0015] To prevent the hanging rope from falling off, a limiting disc is provided at the end of the second guide rod away from the bracket.

[0016] As a preferred embodiment, the main body of the container has a symmetrical structure, and hanging ropes are connected at symmetrical positions.

[0017] To ensure the balance of the counterweight, the line connecting the installation positions of the two hanging ropes of the main body passes through the rotation center of the main body.

[0018] To protect the operators, housings are provided on the outer sides of the first and second guide rods.

[0019] As a preferred embodiment, the sliding door's moving plane is parallel to the turntable's rotation plane.

[0020] The beneficial effects of this utility model are as follows: This utility model is a gear wear testing machine. Unlike existing equipment, the counterweight of this device is located at the far end and is connected by a hanging rope, so it can be easily replaced. In this process, the rotation and winding method of the hanging rope does not need to be changed. In addition, the phenomenon of the counterweight shaking can be avoided by winding the hanging rope. Then, by setting multiple test holes at different positions on the turntable, the connection position can be expanded according to actual needs, and the test holes can be selected according to actual needs.

[0029] Example

[0030] like Figure 1-4 The gear wear testing machine shown includes a test body 2 located at the center of a support 1. The support 1 serves as a support structure, capable of raising the test body 2 to a height convenient for operation, facilitating use by staff. The test body 2 includes a turntable 22 driven by a drive body 3, with the rotation plane of the turntable 22 being a vertical plane. Generally, the upper surface of the support 1 is rectangular, and the vertical plane of the turntable 22 needs to be parallel to the long side of the support 1 to facilitate planning, design, and layout.

[0031] Subsequently, the bracket 1 is symmetrically provided with first guide rods 5 at both ends of the turntable 22, and the rotation axis of the first guide rods 5 is parallel to the rotation axis of the turntable 22. The two ends of the first guide rods 5 are located on the front and rear sides of the turntable 22, respectively. This arrangement facilitates the subsequent winding of the hanging rope.

[0032] Furthermore, it should be noted that the first guide rod 5 is also rotatably connected to the second guide rod 6, and the rotation axis of the second guide rod 6 is set horizontally and perpendicular to the first guide rod 5. Through the staggered arrangement, the hanging rope can be guided to a certain position to connect with the counterweight 7. Moreover, this connection method can make the lifting and lowering of the counterweight 7 more stable by winding multiple guide rods.

[0033] In the above structure, it should be noted that, in order to facilitate connection with the counterweight 7, the end of the second guide rod 6 extends beyond the upper surface of the bracket 1, such as... Figure 1 , 3 As shown, the counterweight 7 can be placed on the side to facilitate lifting and lowering control, and can avoid being obstructed. In addition, the stroke of the counterweight 7 can be greater.

[0034] After completing the above structure, as follows Figure 2 , 4As shown, a main body 9 is rotatably mounted on the turntable 22. The main body 9 is used for testing. To connect the load, hanging ropes are provided at both ends of the main body 9. The other end of the hanging rope passes through the first guide rod 5 and the second guide rod 6 in sequence and is connected to the counterweight 7. In this way, the main body 9 can rotate during the rotation of the turntable 22. During this process, the main body 9 will also rotate relative to the turntable 22. During the rotation, it will also be affected by the load, i.e., the counterweight 7. Testing can be carried out in this way. It should be noted that in the above structure, the main body 9 is a symmetrical structure, and the hanging ropes are connected at symmetrical positions to facilitate the subsequent balancing operation of the counterweight.

[0035] Subsequently, in order to ensure the balance of the counterweight, the line connecting the installation positions of the two hanging ropes of the main body 9 passes through the rotation center of the main body 9. In this way, the rotation of the main body 9 relative to the turntable 22 can be more controllable, and the phenomenon of load imbalance caused by misalignment can be avoided.

[0036] Therefore, the above structure can be used to change the test parameters simply by replacing the counterweight 7 as needed. The presence of the guide rod makes it easy to place the counterweight 7 in a position that is easy to replace. The lifting and lowering of the counterweight 7 is more controllable and stable. Moreover, the special design of the main body 9 makes it easy to balance the load during testing.

[0037] Furthermore, based on the above structure, as follows: Figure 3 As shown, in some cases, if the hanging rope breaks, it could easily injure workers. However, the above design can protect workers. Specifically, to prevent the counterweight 7 from falling, protective shells are provided at both ends of the bracket 1 along the movement path of the counterweight 7. The protective shells can support the counterweight 7 and are positioned above the ground at their lower ends. The protective shells can protect the counterweight 7 from accidental falls.

[0038] Correspondingly, such as Figure 3 As shown, to protect operators, an isolation shell 21 is provided on the outer side of the turntable 22 to prevent the end of the hanging rope from detaching or the main body 9 from separating from the turntable 22. Furthermore, the outer sides of the first guide rod 5 and the second guide rod 6 are also equipped with shells to prevent hand injuries caused by operator error due to the hanging rope.

[0039] Finally, in order to facilitate testing and protect operators, the front end of the turntable 22 is provided with a sliding door 8 that can be opened and closed. It should be noted that in the above structure, the moving plane of the sliding door 8 is parallel to the rotation plane of the turntable 22. The opening method can avoid the harm to the staff caused by various structures flying out, and this opening method also makes it easier for the staff to use the structure.

[0040] Subsequently, in order to prevent the hanging rope from falling off, a limiting disc is provided at the end of the second guide rod 6 away from the bracket 1. The limiting disc protrudes outward from the second guide rod 6, which can prevent the hanging rope from falling off from the end. The limiting disc can be provided at both ends of the hanging rope to limit the position of the hanging rope.

[0041] Finally, for different testing scenarios, the turntable 22 is provided with multiple test holes 23 for placing the object body 9, and the distance between the multiple test holes 23 and the center of the turntable 22 is different. By changing the test holes 23, the test parameters can be changed. Since the distance from the center of the turntable 22 changes, the relative rotational speed of the object body 9 will also change after the turntable 22 rotates one revolution, thus producing different effects.
