Description

Technical Field

[0001] This utility model belongs to the field of dynamometer motor technology, specifically relating to a low-inertia, high-torque dynamometer motor with a damping structure. Background Technology

[0002] A dynamometer is a general term for a system that combines a load simulation device with a torque measuring device. Its main function is to simulate working conditions through a load and measure the instantaneous output torque, speed, and power of the tested component through a torque measuring device. A dynamometer can not only measure the output power of a motor, but also convert the mechanical energy generated by the prime mover into electrical energy. This not only improves energy utilization efficiency, but also meets the needs of modern industry for energy recovery and reuse.

[0003] Currently, low-inertia, high-torque dynamometer motors are prone to vibration during operation, and the motors themselves have poor vibration damping. Prolonged vibration can cause loosening between parts, thus affecting the normal use of the dynamometer motor and testing operations. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0004] The purpose of this invention is to provide a low-inertia, high-torque dynamometer motor with a shock-absorbing structure for existing devices, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a low inertia high torque dynamometer motor with a shock-absorbing structure, including a dynamometer motor, a bearing housing and a mounting plate, wherein a through groove is provided on the top of the mounting plate, an elastic band is movably connected to the inner wall of the through groove, and a connecting ring is movably connected to the outer wall of the elastic band.

[0006] A resistance band is fixedly connected to one side of the connecting ring, and a base plate is fixedly connected to one end of the elastic band. A buffer pad, a damper, and a buffer spring are fixedly connected to the top of the base plate. The resistance band is installed on the dynamometer motor through the elastic band, which can play a certain role in resistance buffering when shaking. The installed damper and buffer spring can play a shock-absorbing effect when the whole working motor shakes, avoiding excessive shaking of the dynamometer motor and causing parts to loosen.

[0007] This utility model further illustrates that one side of the elastic band is sewn with a barbed hook and loop fastener, and one end of the elastic band is sewn with a rough hook and loop fastener. One end of the damper is fixedly connected to a mounting base. The outer wall of the mounting base has a groove, and the inner wall of the groove is movably connected to a retaining plate. The bottom of the retaining plate is fixedly connected to a limiting block. One side of the mounting plate has a limiting slot, which facilitates the disassembly and assembly of the mounting plate and the mounting base. It also allows for the disassembly and assembly of the resistance band and the elastic band, thereby meeting different usage needs and providing convenience for replacement and maintenance.

[0008] This utility model further illustrates that the limiting block is tightly connected to the mounting plate through the limiting slot, and both the limiting block and the limiting slot are T-shaped, which can play a good positioning role, thereby facilitating quick assembly and disassembly operations according to usage needs.

[0009] This utility model further explains that the elastic band is movably connected to the resistance band via hook and loop fasteners and non-hooked hook and loop fasteners, and the resistance band is a rubber resistance band, which facilitates quick and easy connection between the elastic band and the resistance band, while also enabling the resistance band to be stably limited on the dynamometer motor to generate shock-absorbing tension.

[0010] The present invention further explains that the top of the mounting plate is provided with a mounting groove that matches the mounting base, and the mounting base is movably connected to the mounting plate through the mounting groove, which facilitates the connection between the mounting plate and the mounting base, thereby enabling vibration damping of the dynamometer motor.

[0011] This utility model further illustrates that one end of the buffer spring is fixedly connected to the bottom of the mounting base, and the buffer pad is a sponge buffer pad, which can improve the buffering effect during shock absorption and avoid collisions between structures.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0013] (1) By setting up a mounting plate, through groove, elastic band, resistance band, base plate, buffer pad, damper and buffer spring, the resistance band is installed on the dynamometer motor by the elastic band, which can play a certain resistance buffering role when shaking. The installed damper and buffer spring can play a shock-absorbing effect when the whole working generates shaking, avoiding the situation where the dynamometer motor shakes too much and the parts become loose.

[0014] (2) By providing hook and loop fasteners with barbed and rough surfaces, mounting base, groove, card plate, limit card block and limit card slot, it is convenient to disassemble and install the mounting plate and mounting base. At the same time, the resistance band and elastic band can be disassembled and installed, thereby meeting different usage needs and bringing convenience to replacement and maintenance.

Detailed Implementation

[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 The present invention provides a technical solution: a low inertia high torque dynamometer motor with a shock-absorbing structure, including a dynamometer motor 1, a bearing seat 2 and a mounting plate 3. The top of the mounting plate 3 is provided with a through groove 4, the inner wall of the through groove 4 is movably connected with an elastic band 5, and the outer wall of the elastic band 5 is movably connected with a connecting ring 8.

[0024] A resistance band 9 is fixedly connected to one side of the connecting ring 8, and a base plate 10 is fixedly connected to one end of the elastic band 5. A buffer pad 11, a damper 12, and a buffer spring 13 are fixedly connected to the top of the base plate 10. The resistance band 9 is installed on the dynamometer motor 1 through the elastic band 5, which can play a certain role in resistance buffering when shaking. The installed damper 12 and buffer spring 13 can play a shock-absorbing effect when the whole working generates shaking, so as to avoid the whole dynamometer motor 1 shaking too much and causing parts to loosen.

[0025] In this embodiment, one side of the elastic band 5 is sewn with a barbed Velcro 6, and one end of the elastic band 5 is sewn with a rough Velcro 7. One end of the damper 12 is fixedly connected to a mounting base 14. The outer wall of the mounting base 14 has a groove 15, and the inner wall of the groove 15 is movably connected to a retaining plate 16. The bottom of the retaining plate 16 is fixedly connected to a limiting retaining block 17. One side of the mounting plate 3 has a limiting retaining groove 18, which facilitates the disassembly and assembly of the mounting plate 3 and the mounting base 14. At the same time, the resistance band 9 and the elastic band 5 can also be disassembled and assembled, thereby meeting different usage needs and bringing convenience to replacement and maintenance.

[0026] Example 2

[0027] Based on Embodiment 1, a preferred embodiment of the low-inertia, high-torque dynamometer motor with a damping structure provided by this utility model is, for example... Figures 1 to 5 As shown: The limiting block 17 is tightly connected to the mounting plate 3 through the limiting slot 18. Both the limiting block 17 and the limiting slot 18 are T-shaped, which can play a good positioning role, thus facilitating quick disassembly and assembly operations according to the needs of use.

[0028] In this embodiment, the elastic band 5 is movably connected to the resistance band 9 via the hook-and-loop fastener 6 and the loop fastener 7. The resistance band 9 is a rubber resistance band, which facilitates quick and easy connection between the elastic band 5 and the resistance band 9. At the same time, it enables the resistance band 9 to be stably limited on the dynamometer motor 1 to generate shock-absorbing tension.

[0029] Furthermore, the top of the mounting plate 3 is provided with a mounting groove that matches the mounting base 14, and the mounting base 14 is movably connected to the mounting plate 3 through the mounting groove, so as to facilitate the connection between the mounting plate 3 and the mounting base 14, thereby enabling the dynamometer motor 1 to be vibration damped.

[0030] Furthermore, one end of the buffer spring 13 is fixedly connected to the bottom of the mounting base 14, and the buffer pad 11 is a sponge buffer pad, which can improve the buffering effect during shock absorption and prevent collisions between structures.

[0031] In use, the mounting plate 3 is installed on the mounting base 14, and the limiting block 17 at the bottom of the clamping plate 16 is inserted into the limiting slot 18. At the same time, the clamping plate 16 is inserted into the groove 15 outside the mounting base 14, thereby connecting the mounting plate 3 and the mounting base 14. The elastic band 5 is then passed through the through slot 4 on the mounting plate 3, and the resistance band 9 is placed on the dynamometer motor 1 and installed by connecting ring 8 to one end of the elastic band 5. The resistance band 9 is then attached by hook and loop fastener 6 and hook and loop fastener 7, so that the resistance band 9 can be stably installed on the dynamometer motor 1. When the dynamometer motor 1 vibrates during operation, the resistance band 9 and the elastic band 5 can significantly reduce the amplitude of the vibration under the force of the vibration. Furthermore, the damper 12 at the bottom of the mounting plate 3 further reduces the degree of vibration of the dynamometer motor 1, making it more stable during use.
