Description

Technical Field

[0001] This utility model relates to the technical field of gear strength measuring equipment, specifically a gear strength measuring gauge. Background Technology

[0002] Gears, as an important mechanical transmission component, are widely used in modern industry. Their main function is to transmit power and change the speed and direction of motion, and they are widely used in automobiles, machinery manufacturing, aerospace, and other fields. The performance and quality of gears directly affect the operating efficiency and reliability of mechanical equipment; therefore, strength testing is crucial during gear manufacturing.

[0003] The strength of a gear refers to its maximum load-bearing capacity during operation, which determines its reliability and durability in actual use. Insufficient gear strength can lead to problems such as tooth breakage and deformation during use, causing mechanical equipment to malfunction or even causing safety accidents. Therefore, during gear manufacturing, rigorous strength testing is necessary to ensure that gears meet design and usage requirements.

[0004] To address the aforementioned issues and meet market demand for efficient, accurate, and versatile gear strength testing devices, a novel gear strength measuring tool is proposed. This tool can quickly and accurately test gear strength during the gear manufacturing process, ensuring gear compliance. Utility Model Content

[0005] This utility model addresses the problem that existing technical solutions are too simplistic by providing a gear strength measuring fixture that is significantly different from existing technologies, thus solving the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gear strength measuring tool, comprising a tooling base, wherein the top of the tooling base is provided with a locking member for positioning the side tooth blocks of the gear to fix the gear, the bottom of the tooling base is provided with a structure for fixing it on a bench vise, and the top of the tooling base is provided with a limiting member for cooperating with the gear, wherein a torque wrench for applying torque is connected to the limiting member.

[0007] Preferably, the tooling base includes a support plate, a clamping seat, a C-shaped surrounding block, and a plug. The bottom of the support plate is connected to a clamping seat for clamping and limiting on a bench vise. A C-shaped surrounding block is provided on one side of the top of the support plate. A plug for inserting and fixing a gear is provided at the central axis point area of ​​the inner circle of the C-shaped surrounding block on the top of the support plate. The locking component and the limiting component respectively cooperate with the C-shaped surrounding block.

[0008] Preferably, the outer wall of the clamping seat is provided with a rough texture to increase friction, prevent slippage, and enhance clamping stability.

[0009] Preferably, the locking component includes a mounting block and a locking head. The mounting block is mounted on the top of the support plate, and the mounting block and the C-shaped surrounding block form a U-shaped structure. The locking head is connected to the mounting block, and the mounting block and the locking head form a "convex" structure. The locking head is located inside the C-shaped surrounding block for engaging the gear teeth for fixed positioning.

[0010] Preferably, the limiting member includes a circular pressure cap, a mating interface, and a semi-ring. The circular pressure cap has a mating interface in the middle area for connecting with a torque wrench, and the bottom of the circular pressure cap is connected to a semi-ring for engaging with a gear.

[0011] Preferably, the semi-ring is used to be inserted between the mounting block and the locking head. The outer wall of the semi-ring is in contact with the inner wall of the C-shaped block. The inner wall of the semi-ring is provided with a number of toothed grooves. The toothed grooves are used to engage with the toothed blocks on the gear, and the toothed grooves are located on the opposite side of the locking head.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the gear strength measuring fixture achieves efficient fixation of the gear through the synergistic effect of the locking and limiting components. The locking head can be accurately embedded into the gap between the side teeth of the gear, and the insertion post limits the gear, effectively preventing gear displacement or loosening, ensuring the stability of the gear during the testing process, thereby improving the accuracy and reliability of the test.

[0013] Meanwhile, the positioning head is designed not only to fix the gear and assist in inspection, but also to provide a certain positioning function, ensuring that the inner tooth groove of the semi-ring is precisely vertically aligned with the tooth blocks on the gear. This design greatly improves the fit between the gear and the inspection fixture.

[0014] In addition, the tooling base of this utility model is provided with a clamping seat at the bottom, which can be clamped on the bench vise to achieve overall fixation. The operation is simple and quick. The entire testing process only requires inserting the gear into the insert and pressing it to fix it, and then using a torque wrench to perform the test. There is no need for complicated assembly and adjustment, which greatly improves the testing efficiency.

[0015] The outer wall of the clamping seat has a textured surface, which significantly enhances the friction between the clamping seat and the bench vise, thereby improving the stability of the clamping and ensuring the smooth progress of the testing process. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a gear strength measuring tool, including a tooling base 1, a bearing plate 101, a clamping seat 102, a C-shaped surrounding block 103, a plug 104, a locking component 2, a mounting block 201, a locking head 202, a limiting component 3, a circular pressure cap 301, a mating interface 302, and a semi-ring 303. The tooling base 1 has a locking component 2 at the top for positioning the side teeth of the gear to fix the gear, and a structure at the bottom of the tooling base 1 for fixing it on a bench vise. The tooling base 1 has a limiting component 3 inside the top for cooperating with the gear, and a torque wrench for applying torque is connected to the limiting component 3.

[0025] The tooling base 1 includes a support plate 101, a clamping seat 102, a C-shaped surrounding block 103, and a plug 104. The bottom of the support plate 101 is connected to the clamping seat 102 for clamping and limiting on the bench vise. The top side of the support plate 101 is provided with a C-shaped surrounding block 103. The top of the support plate 101 is provided with a plug 104 for inserting and fixing gears in the central axis area of ​​the inner circle of the C-shaped surrounding block 103. The locking member 2 and the limiting member 3 respectively cooperate with the C-shaped surrounding block 103.

[0026] The outer wall of the clamping seat 102 is provided with a rough texture to increase friction, prevent slippage and enhance clamping stability.

[0027] The locking component 2 includes a mounting block 201 and a locking head 202. The mounting block 201 is mounted on the top of the support plate 101, and the mounting block 201 and the C-shaped surrounding block 103 form a U-shaped structure. The locking head 202 is connected to the mounting block 201, and the mounting block 201 and the locking head 202 form a "convex" structure. The locking head 202 is located inside the C-shaped surrounding block 103 for engaging the gear teeth for fixed positioning.

[0028] The limiting component 3 includes a circular pressure cap 301, a mating interface 302, and a semi-ring 303. The circular pressure cap 301 has a mating interface 302 in the middle area for connecting with a torque wrench. The bottom of the circular pressure cap 301 is connected to a semi-ring 303, which is used to engage with a gear.

[0029] The semi-ring 303 is used to be inserted between the mounting block 201 and the locking head 202. The outer wall of the semi-ring 303 fits against the inner wall of the C-shaped surrounding block 103. The inner wall of the semi-ring 303 is provided with several tooth grooves, which are used to engage with the tooth blocks on the gear, and the tooth grooves are located on the opposite side of the locking head 202.

[0030] Working principle: According to Figure 1 As shown, first, the mounting block 201 is firmly fixed to the bearing plate 101 with screws, so that it and the C-shaped surrounding block 103 together form a loop structure. At this time, the locking head 202 on the mounting block 201 should be accurately located in the inner area of ​​the C-shaped surrounding block 103 to prepare for the subsequent gear fixing.

[0031] Before gear inspection, the clamping seat 102 of the tooling base 1 needs to be clamped in a bench vise to fix the tooling base 1 as a whole and ensure that the entire device remains stable during the inspection process. Then, the center hole of the gear to be inspected is precisely fitted onto the insert 104, and the gear is gently pressed down to make its bottom contact tightly with the bearing plate 101. At the same time, it is ensured that the locking head 202 can be accurately embedded in the gap between the side teeth of the gear, thereby achieving the initial positioning and fixing of the gear.

[0032] Next, insert the semi-ring 303 on the circular pressure cap 301 into the C-shaped block 103. At this time, the fixing effect of the locking head 202 on the gear can not only stabilize the gear, but also play a certain positioning role, so that the tooth groove on the inner side of the semi-ring 303 can be accurately vertically aligned with the tooth block on the gear. Continue to press the circular pressure cap 301 down so that the tooth groove on the inner side of the semi-ring 303 can be tightly engaged with the tooth block on the gear, thereby further enhancing the fixing effect of the gear and ensuring that the gear will not be displaced or loosened during the testing process.

[0033] After completing the above fixing and positioning operations, adjust the parameter values ​​on the torque wrench in advance according to the testing requirements, insert the end of the torque wrench into the mating interface 302 on the circular pressure cap 301, and gently rotate the torque wrench. By observing the change in the value on the torque wrench as it rotates, the strength performance of the gear under stress can be accurately measured. In this way, the load-bearing capacity and structural stability of the gear can be accurately evaluated, thereby achieving effective testing of gear strength. This is the working principle of the gear strength measuring instrument.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
