Description

Technical Field

[0001] The utility model belongs to the technical field of carbon-carbon furnace tube testing equipment, in particular to a tool for testing the rotating dynamic friction of a carbon-carbon furnace tube. Background Art

[0002] The rotary kiln tube is generally made of carbon-carbon material. During use, the rotary kiln tube is in a rolling state and is driven by the supporting wheel at the bottom. The most important parameter of the service life of the rotary kiln tube is the friction service life of the rotary kiln tube during the rolling process.

[0003] Currently, there are no special tools for testing the newly designed rotary kiln tubes. Generally, they are directly installed on the rotary kiln for testing, which results in high testing costs and inconvenience. Utility Model Content

[0004] In response to the above problems, the present invention provides a rotary friction test fixture for carbon-carbon furnace tubes. By placing the carbon-carbon furnace tubes on this fixture, the rolling friction test of the furnace tubes can be carried out instead of the rotary kiln, thereby detecting the wear of the carbon-carbon furnace tubes and obtaining their friction service life. The fixture has a simple structure and is easy to use, which can reduce the testing cost of the furnace tubes.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A tooling for testing the rotating friction of a carbon-carbon furnace tube comprises a machine base distributed at the bottom of both ends of the carbon-carbon furnace tube, a driver being provided at both ends of each machine base, and two friction wheels being provided on each driver for driving the carbon-carbon furnace tube to rotate. The friction wheel is mounted on the driver through a rotating shaft, and a driven gear is connected to the other end of the rotating shaft; the driven gear is connected to the motor through a gear transmission mechanism.

[0007] As a further improvement to the above solution, the driven gear meshes with the driving gear via a transmission gear on the driver; the driving gear's shaft is connected to a motor. This design ensures higher transmission efficiency, reduces energy loss, and improves the overall energy efficiency of the test fixture.

[0008] As a further improvement to the above solution, the motor is provided with a reducer. By using the reducer, the torque output of the motor can be increased, making the rotation of the carbon-carbon furnace tube more stable, thereby improving the accuracy and reliability of the test.

[0009] As a further improvement to the above solution, a mounting slot is provided on the upper end of the base, and the driver is installed in the mounting slot. This structural design facilitates the installation and adjustment of the driver, and is also convenient for maintenance and replacement, thereby improving the practicality and maintainability of the tooling.

[0010] As a further improvement to the above solution, the driver frame is triangular in shape; the friction wheels are mounted at two corners of the triangular frame; and the side of the triangular frame facing the carbon-carbon furnace tube has a concave arc surface. This design increases structural stability, and the concave arc surface better adapts to the shape of the furnace tube, ensuring stability and safety during testing.

[0011] As a further improvement to the above solution, the base is wider at the bottom and narrower at the top. This structural design helps to improve the stability of the base, especially when the furnace tube rotates, it can reduce the shaking of the base and ensure the stability and accuracy of the test.

[0012] As a further improvement to the above solution, reinforcing ribs are provided on both sides of the machine base, which can significantly improve the structural strength of the machine base, making it less likely to deform or damage under long-term operation and high load conditions, thereby extending the service life of the tooling.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Through the aforementioned improvements, the present invention's rotary friction testing fixture for carbon-carbon furnace tubes achieves multiple advantages, including simple structure, ease of use, low testing costs, clear visibility of wear, and accurate measurement of friction service life. Not only can it replace rotary kilns for rolling friction testing of furnace tubes, it also effectively reduces testing costs and improves efficiency, significantly contributing to extending the service life of carbon-carbon furnace tubes and reducing production costs.

[0020] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with the embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0021] 1. Overview of tooling structure:

[0022] like Figure 1-4 As shown, this embodiment provides a rotary friction test fixture for a carbon-carbon furnace tube 1. The fixture primarily consists of a base 2, a driver 3, a friction wheel 4, a rotating shaft, a driven gear 7, a driving gear 5, a motor 8, and a reducer 9. The fixture is designed to simulate the rolling friction test of a rotary kiln tube to evaluate the wear and friction service life of the carbon-carbon furnace tube 1. The base 2 has a lifting hole.

[0023] 2. Design of base 2:

[0024] The base 2 is located at the bottom of both ends of the carbon-carbon furnace tube 1 and is designed to be wide at the bottom and narrow at the top. Reinforcement ribs are provided on both sides to improve the stability and strength of the overall structure. A mounting slot is provided at the top of the base 2 for mounting the driver 3.

[0025] 3. Driver 3 and friction wheel 4:

[0026] Each base 2 is equipped with a driver 3 at both ends. The driver 3's frame is designed in a triangular shape to enhance structural stability. A friction wheel 4 is mounted at each corner of the triangular frame and is attached to the driver 3 via a rotating shaft. The other end of the shaft is connected to a driven gear 7.

[0027] 4. Gear transmission and motor 8:

[0028] Driven gear 7 meshes with driving gear 5 via transmission gear 6 on driver 3. The rotating shaft of driving gear 5 is directly connected to motor 8. Motor 8 is equipped with a reducer 9 to increase torque output and ensure smooth rotation of carbon-carbon furnace tube 1. The use of reducer 9 also helps to reduce the speed of motor 8, improving the accuracy of the test.

[0029] 5. Operation of test tooling:

[0030] During testing, the carbon-carbon furnace tube 1 is placed in the mounting slot of the machine base 2, with the friction wheel 4 in contact with the bottom of the tube. After motor 8 is started, the gear transmission mechanism drives the friction wheel 4 to rotate, thereby causing the carbon-carbon furnace tube 1 to roll. The speed and torque of motor 8 can be adjusted using a reducer 9 and controller to simulate different operating conditions.

[0031] 6. Technical effects:

[0032] The test fixture of this embodiment has a simple structure and is easy to operate, effectively simulating the actual operating conditions of rotary kiln tubes. By adjusting the speed and torque of motor 8, the friction performance of carbon-carbon furnace tubes 1 can be tested under different operating conditions. Furthermore, the fixture's stability and strength ensure reliable and safe testing over extended periods. The test results help predict the service life of the furnace tubes, providing an important reference for production and maintenance.

[0033] 7. Usage:

[0034] This fixture is designed for rotating dynamic friction tests on carbon-carbon furnace tubes. It features dual rotating tables on either side and four friction wheels, increasing friction and shortening test times. The actuator can be adjusted on the base, making it suitable for a variety of circular tube friction tests.

[0035] The motor 8 drives the friction wheel, causing it to rotate. The weight of the product creates gravity, generating dynamic friction. The friction is observed over a period of time to simulate the friction life of the rotary kiln tube.

[0036] The rotating shaft is fixed by bearings at both ends, and gears on both sides are fixed by keyways.
