Description

Technical Field

[0001] This utility model relates to the field of testing and processing of transmission teeth, and in particular to a performance testing device for transmission tooth parts. Background Technology

[0002] Currently, transmission gear parts often experience issues during production due to various reasons, such as impacts, burrs, flanging, or dimensional defects caused by mold damage. These defects can affect subsequent assembly and use. Before assembly and use, the transmission gear parts are functionally sound. However, during production, adjustment gear function gauges are needed to simulate the actual usage environment.

[0003] Current commonly used inspection tools typically combine a copying tool with a coordinate measuring machine (CMM). The depth of the copying tool's entry is used to determine whether the tool has completely passed through the straight teeth and made contact with the bottom. This method has the following drawbacks:

[0004] First, during testing, it is necessary to read the data displayed at each measuring point and determine whether it is qualified by the height difference, which is inefficient.

[0005] Secondly, there may be errors or omissions when reading data, leading to misjudgments.

[0006] Third, when a large number of tests are required, coordinate measuring machines (CMMs) are inefficient and require multiple sets of testing equipment, personnel, and facilities, which increases testing costs significantly.

[0007] Therefore, this study aims to develop a simple and convenient testing fixture for rapid detection. Reducing testing costs is a key issue that needs to be addressed. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a performance testing device for transmission gear parts.

[0009] The technical solution of this utility model is: a performance testing device for transmission gear parts, comprising:

[0010] The test motherboard is arranged in a straight line.

[0011] The mounting plate is set perpendicularly to the test motherboard.

[0012] A test vertical plate is parallel to the test main board and is connected to the mounting plate, forming a test space between the test vertical plate, the mounting plate and the test main board;

[0013] The transmission gear component to be tested passes through the mounting plate from top to bottom in the test space, and the transmission gear is located in the test space. At the same time, a toothed workpiece passes between the test main plate and the test vertical plate. The toothed part of the toothed workpiece cooperates with the transmission gear, and external force acts on the rod part of the transmission gear component or the toothed workpiece.

[0014] Furthermore, it also includes a lower mounting plate, which is perpendicular to the test main board and parallel to the upper mounting plate, with the lower mounting plate located below the upper mounting plate. By setting the lower mounting plate, the transmission gear component to be tested passes through both the upper and lower mounting plates from top to bottom, ensuring that both are positioned vertically.

[0015] Furthermore, both the upper and lower mounting plates are provided with mounting holes, and the spindle direction of the transmission gear components within the two mounting holes is parallel to that of the test main board. This ensures the stable placement of the transmission gear components and facilitates subsequent testing.

[0016] Furthermore, the transmission gear components to be tested include:

[0017] The transmission gear section has transmission teeth arranged circumferentially at its upper end; and

[0018] The rod portion has an external thread and is located below the transmission gear portion. The transmission gear portion is positioned horizontally, while the rod portion is positioned vertically.

[0019] Furthermore, a test nut is provided at the lower end of the rod of the transmission gear component. The test nut engages with the rod to lock it onto the mounting plate, facilitating the testing of the toothed workpiece.

[0020] Furthermore, the perforated workpiece includes:

[0021] A test rod that passes through both the test vertical plate and the test main plate;

[0022] The toothed portion is located circumferentially on the test rod.

[0023] Furthermore, a limiting ring is provided at one end of the test rod, and the limiting ring contacts the outer side of the test vertical plate or test main plate. This ensures the stable setting of the test rod, and the limiting ring ensures that the position is correctly installed during installation, facilitating subsequent testing.

[0024] Furthermore, a rotating ring protrudes circumferentially from the test rod, and this rotating ring is fitted onto the test main board or test vertical plate. This ensures stable rotation of the test rod.

[0025] Furthermore, one end of the test rod is provided with an internal hexagonal hole, which mates with a torque wrench, facilitating subsequent torque testing.

[0026] Furthermore, the toothed workpiece is inserted from the test vertical plate toward the test main plate, and the limiting ring, rotating ring, and internal hexagonal hole on the toothed workpiece are all located on the side close to the test vertical plate. This facilitates uniform positioning for the testing workers and improves the stability of the test.

[0027] The beneficial technical effects of this invention are as follows: by meshing the toothed workpiece and the transmission gear parts within the test space, the stability of their performance can be detected during testing with external force or a torque wrench. This not only simplifies the testing method and improves efficiency, but also reduces the likelihood of misjudgment by determining product qualification through torque. The increased testing efficiency significantly reduces the need for inspection tools and personnel, thereby lowering testing costs. Attached Figure Description

[0042] The transmission gear component 4 to be tested passes through the mounting plate 2 from top to bottom in the test space, and the transmission gear 41 is in the test space. At the same time, the toothed workpiece 5 also passes between the test main plate 1 and the test vertical plate 3. The toothed part 51 of the toothed workpiece 5 cooperates with the transmission gear 41, and external force acts on the rod part 43 of the transmission gear component 4 or the toothed workpiece 5.

[0043] Furthermore, it also includes a lower mounting plate 6, which is perpendicular to the test main board 1 and parallel to the upper mounting plate 2, with the lower mounting plate 6 located below the upper mounting plate 2. By setting the lower mounting plate 6, the transmission gear component 4 to be tested passes through the upper mounting plate 2 and the lower mounting plate 6 from top to bottom, ensuring that both are set in a vertical direction.

[0044] Furthermore, mounting holes are provided on both the upper mounting plate 2 and the lower mounting plate 6, and the spindle direction of the transmission gear component 4 within the two mounting holes is parallel to that of the test main plate 1. This ensures the stable setting of the transmission gear component 4 and facilitates subsequent testing.

[0045] Furthermore, the transmission gear component 4 to be tested includes:

[0046] A transmission gear 41, the upper end of which is provided with transmission teeth 42 in the circumferential direction; and

[0047] The rod portion 43 has an external thread and is located below the transmission gear portion 41. The transmission gear portion 41 is positioned horizontally, while the rod portion 43 is positioned vertically.

[0048] Furthermore, a test nut 7 is provided at the lower end of the rod 43 of the transmission gear part 4. By cooperating with the rod 43, the test nut 7 locks it onto the mounting plate 6, facilitating the testing of the toothed workpiece 5.

[0049] Furthermore, the toothed workpiece 5 includes:

[0050] Test rod 52 passes through both test vertical plate 3 and test main plate 1;

[0051] The spline tooth portion 51 is located on the circumferential direction of the test rod 52.

[0052] Further, a limit ring 53 is disposed at one end of the test rod 52, and the limit ring 53 is in contact with the outer side of the test vertical plate 3 or the test main plate 1. This ensures the stable arrangement of the test rod 52, and the limit ring 53 can ensure that the position is installed in place during installation, facilitating subsequent tests.

[0053] Further, a rotating ring 54 is disposed protruding in the circumferential direction of the rod portion 43 of the test rod 52, and the rotating ring 54 is sleeved with the test main plate 1 or the test vertical plate 3. This ensures that the rotation of the test rod 52 is stable.

[0054] Further, an inner hexagonal hole 55 is provided at one end of the test rod 52, and the inner hexagonal hole 55 is matched with a torque wrench, facilitating subsequent torque tests.

[0055] Further, the spline workpiece 5 is inserted from the test vertical plate 3 toward the test main plate 1, and the limit ring 53, the rotating ring 54 and the inner hexagonal hole 55 on the spline workpiece 5 are all located on the side close to the test vertical plate 3. This facilitates the unified position of test workers and improves the test stability.

[0056] Through the engagement of the spline tooth portion 51 and the transmission tooth portion 41 between the spline workpiece 5 and the transmission tooth part 4 in the test space, the stability of their performance can be detected when they are tested by external force or a torque wrench. This not only simplifies the detection method and improves efficiency, but also judges whether the product is qualified through torque, which is less prone to misjudgment. Due to the improvement of detection efficiency, the number of inspection tools and testing personnel can be greatly reduced, and the detection cost is lowered.

[0057] The test of transmission tooth parts is divided into two modes: test with nut and test without nut.

[0058] When conducting the test without a nut, install the product into the test fixture from top to bottom, insert the spline workpiece transversely, make the spline tooth portion cooperate with the transmission tooth portion, rotate counterclockwise, and manually turn the product. If the product can drive the spline workpiece to rotate easily, it means that the performance requirement of the maximum unloading torque of 0.5 Nm is met, and the product is qualified.

[0059] When conducting the test with a nut, install the product into the test fixture from top to bottom, insert the spline workpiece transversely, and make the spline tooth portion cooperate with the transmission tooth portion. Then use an open-end wrench to tighten the nut clockwise to lock and secure the product and the test fixture. Next, use a torque wrench to apply force clockwise to twist the inner hexagonal hole on the matched spline workpiece, stop until the torque wrench slips, and read the breaking torque value on the torque wrench. If the value is greater than the performance requirement of the minimum blocking torque of 5 Nm specified on the product drawing, the product is qualified.

[0060] Only products that simultaneously meet the performance requirements of a maximum unloading torque of 0.5 Nm and a minimum blocking torque of 5 Nm through the above tests can be considered qualified.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
