Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission testing technology, and in particular to a testing mechanism for the meshing performance of synchronous belts and synchronous pulleys. Background Technology

[0002] Synchronous belt drive is a mechanical transmission method that relies on the meshing of belt teeth and pulley teeth to transmit power. It boasts advantages such as accurate transmission ratio, high transmission efficiency, low noise, and no need for lubrication, making it widely used in various industrial equipment. The meshing quality between the synchronous belt and the toothed idler pulley directly determines the smoothness of the transmission, noise level, and service life. Currently, in production and quality inspection, the performance evaluation of synchronous belt drives mostly involves mounting them on the complete machine for no-load or load operation testing. This method has significant drawbacks: the testing process is limited by the overall machine structure, the operating space is narrow, adjustments are inconvenient, it is difficult to quickly and accurately adjust the center distance between the two pulleys to adapt to different specifications of synchronous belts, and the background noise and vibration of the entire machine severely interfere with the detection of the synchronous belt's own meshing noise, affecting the accuracy of the judgment. Therefore, there is an urgent need in this field for a dedicated testing platform with an independent structure, convenient adjustment, and a controllable testing environment to achieve efficient and accurate evaluation of synchronous belt drive performance. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide a timing belt and timing pulley meshing performance testing mechanism, which has an independent structure, is easy to adjust, and can quickly and accurately adjust the center distance of the timing pulley to adapt to timing belts of different specifications.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a mechanism for testing the meshing performance of a timing belt and a timing pulley, comprising: The bottom frame has a T-shaped slide groove. A motor mounting plate is fixedly installed on one side of the T-shaped slide groove, and an adjustment plate is slidably installed on the other side of the T-shaped slide groove. A drive motor is disposed below the motor mounting plate. The output end of the drive motor passes through the motor mounting plate and is connected to an active toothed idler gear. The active toothed idler gear is located above the motor mounting plate. The adjustment plate is configured to slide and be fixed on the T-shaped groove. A driven toothed idler wheel is rotatably arranged above the adjustment plate. A timing belt to be tested is sleeved between the driven toothed idler wheel and the driving toothed idler wheel.

[0005] Preferably, an adjustment seat is provided on the side of the adjustment plate away from the active toothed idler wheel. The adjustment seat is configured to slide and be fixed on the T-shaped slide groove. A threaded rod is threadedly connected to the adjustment seat. One end of the threaded rod is connected to the adjustment plate, and the other end of the threaded rod is provided with a knob. When the adjustment seat is fixed, rotating the knob can adjust the position of the adjustment plate.

[0006] Preferably, the adjusting seat is engaged with the slider nut in the T-shaped groove by an internal hexagonal head screw and can be slidably locked.

[0007] Preferably, the adjusting plate is engaged with the slider nut in the T-shaped groove by an internal hexagonal head screw and can be slidably locked.

[0008] The beneficial effects of this utility model are as follows: (1) The drive motor, active toothed idler wheel, driven toothed idler wheel and adjustment mechanism are integrated into a stable frame to form an independent detection environment and effectively isolate external interference.

[0009] (2) The system combines coarse and fine adjustment. First, the center distance is quickly coarsely adjusted by sliding the adjustment plate, and then the tension is finely adjusted by the independent fine adjustment knob, which realizes the precision and convenience of tension control.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0018] like Figure 1 and 2As shown, this embodiment provides a timing belt 8 and timing belt 8 wheel meshing performance testing mechanism, including a bottom frame 1, which serves as the basic support platform for the entire mechanism. The bottom frame 1 is constructed using standard industrial aluminum profiles such as 4040 or 4080, connected by angle brackets, providing sufficient rigidity and stability to ensure that no additional interference is introduced during the testing process due to its own vibration. At least parallel T-shaped grooves 2 are machined along the length of the top surface of the bottom frame 1.

[0019] On the left side of T-shaped groove 2 (with Figure 1 (Taking a specific angle as an example), a motor mounting plate 3 is fixedly installed using hexagonal head screws 91. A drive motor 4 is bolted to the bottom of the motor mounting plate 3. In this embodiment, the drive motor 4 is preferably a speed-regulating motor to test the performance of the synchronous belt 8 at different speeds. The output shaft of the drive motor 4 passes vertically upward through a pre-set through hole on the motor mounting plate 3 and is fixedly installed with an active toothed idler gear 5.

[0020] On the right side of the T-shaped slide 2, there is a movable timing belt 8 tensioning and adjustment system. This system mainly includes an adjustment plate 61 and an adjustment seat 62.

[0021] The bottom of the adjusting plate 61 is engaged with the slider nut 92 embedded in the T-shaped groove 2 via an internal hexagonal head screw 91, allowing the adjusting plate 61 to slide freely on the T-shaped groove 2 and to be rigidly locked at the required position by tightening the screw. A driven toothed idler wheel 7 is rotatably mounted on the top of the adjusting plate 61 via a seated bearing.

[0022] The adjusting seat 62 also achieves sliding and locking functions through the internal hexagonal head screw 91 and the slider nut 92 in the T-shaped groove 2. It is located on the right side of the adjusting plate 61. A threaded rod 63 is horizontally threaded onto the adjusting seat 62. The left end of the threaded rod 63 is connected to the right side of the adjusting plate 61 through a spherical bearing, and a knob 64 is fixedly installed on the right end.

[0023] The synchronous belt 8 to be tested is fitted between the driving toothed idler 5 and the driven toothed idler 7.

[0024] When testing a specific specification of synchronous belt 8, the operator first loosens the socket head cap screws 91 of the locking adjustment plate 61 and the adjustment seat 62. Then, the operator pushes the adjustment seat 62 or the adjustment plate 61 directly by hand, allowing it to slide on the T-slot 2 for coarse adjustment of the center distance. Subsequently, the adjustment seat 62 is initially locked. At this point, rotating the knob 64 clockwise or counterclockwise converts the rotational movement of the threaded rod 63 into its own axial movement, precisely pushing or pulling the adjustment plate 61 to achieve fine adjustment of the center distance. This process allows for very precise control of the tension of the synchronous belt 8. The operator can rotate the knob 64 while feeling the tension of the synchronous belt 8 by hand until the ideal tension is achieved. Finally, the socket head cap screws 91 of the adjustment plate 61 are completely tightened, locking the entire adjustment system completely onto the bottom frame 1. When the drive motor 4 is started, the active toothed idler wheel 5 begins to rotate, driving the driven toothed idler wheel 7 to rotate via the synchronous belt 8. Quality inspectors can then observe the misalignment of the synchronous belt 8 closely on such an independent and quiet platform, listen for any abnormal noises during engagement, and use equipment such as vibration meters to measure its vibration data, thereby comprehensively and accurately evaluating the engagement performance of the synchronous belt 8.

[0025] This invention creates an ideal testing environment free from interference from the entire machine through an independent bottom frame 1 and a precision T-shaped slide 2 adjustment system; the combination of coarse and fine adjustment makes the center distance adjustment both fast and accurate, greatly improving testing efficiency and applicability; the entire mechanism is stable and easy to operate.

[0026] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
