[0002] A tool for testing radial force is a professional tool specially used to accurately measure the magnitude and characteristics of the force exerted on rotating mechanical parts in the radial direction. It is mainly composed of a fixed base, an electric power sensor, connecting components and an adapter device. The fixed base provides a stable support platform to ensure that the position of the tool remains fixed during the entire test process. The force sensor is the core component, which has high sensitivity and precise measurement range, and can accurately convert the radial force exerted on it by the rotating component into an electrical signal. The connecting component is used to tightly connect the component to be tested with the force sensor to ensure effective force transmission and minimize force loss and deviation. The adapter device can be adjusted and matched according to the different types and sizes of rotating components to be tested, so that the tool can be widely used in radial force testing of various mechanical products, such as motor shafts, gear shafts, etc. The radial force data obtained by the tool is of great significance for analyzing the working status of rotating components, performance optimization, fault diagnosis and reliability design of mechanical systems;

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0021] See also Figure 1-3 , the utility model provides a technical solution:
[0022] Embodiment 1: A tool for testing radial force, including a power output shaft 4 and a base 1, an inner ring 6 is provided on the outside of the power output shaft 4, an oil-free bearing 7 is provided on the outside of the inner ring 6, and an outer ring 8 is provided on the outside of the oil-free bearing 7, the oil-free bearing 7 is sleeved on the inner ring 6, the inner ring 6 is sleeved on the outer wall of the power output shaft 4, the outer ring 8 is sleeved on the outer wall of the oil-free bearing 7, a pressure plate 9 is provided at the other end of the outer ring 8, a bolt 10 is provided in the middle of the pressure plate 9, a flat key 5 is provided inside the power output shaft 4, and the flat key 5 slides The dynamic connection is inside the inner ring 6, and an inner hole 14 is opened inside the pressure plate 9. The inner hole 14 corresponds to the bolt 10, and the bolt 10 is installed in the inner hole 14. The top of the base 1 is fixedly connected to the fixed plate 3, the outer ring 8 is arranged on one side of the fixed plate 3, the top of the base 1 is fixedly connected to the motor 2, the power output shaft 4 is fixedly connected to the output end of the motor 2, the top of the outer ring 8 is fixedly connected to the connecting pipe 11, the other end of the connecting pipe 11 is fixedly connected to the pressure gauge 13, and the outer side wall of the connecting pipe 11 is provided with a valve 12.
[0023] At the outset, motor 2, located atop base 1, is turned on. It immediately spins and generates power, which is precisely transmitted to power take-off shaft 4. A key connector, flat key 5, smoothly transmits power from power take-off shaft 4 to inner ring 6, while simultaneously exerting a radial force firmly against outer ring 8. In this state, oil-free bearing 7 begins testing. As the test progresses, dynamic radial torque values are gradually acquired, and a connected pressure gauge 13 displays the internal pressure in real time. Based on this data, personnel can operate control valve 12 to relieve pressure, ensuring a safe and stable testing process. After the dynamic test is complete, motor 2 is turned off, cutting off power transmission to power take-off shaft 4. Only the radial force applied to outer ring 8 remains. Oil-free bearing 7 then enters the static testing phase, where static radial torque values can be acquired. In the entire device, the design of the pressure plate 9 is unique and can be easily removed from the inner hole 14 by the bolt 10. This convenient disassembly method provides great convenience for the maintenance of the equipment and the replacement of components. Through the close cooperation and coordinated operation between the motor 2, power output shaft 4, flat key 5, inner ring 6, outer ring 8, pressure plate 9 and related components, not only the detection process of the oil-free bearing 7 is made more scientific and efficient, and the dynamic and static radial torque values can be accurately obtained, but also it shows great convenience in the maintenance of the equipment, significantly improves work efficiency, reduces the time and labor costs required for detection and maintenance, and provides strong technical support and guarantee for related industrial production.
[0024] The working principle is to first start the motor 2 on top of the base 1. Under the action of motor 2, power is transmitted to the power output shaft 4. The power output shaft 4 transmits power to the inner ring 6 via the flat key 5, and simultaneously applies radial force against the outer ring 8. This tests the oil-free bearing 7 and prompts the determination of the dynamic radial torque value. The pressure gauge 13 will display the internal pressure, and the control valve 12 will release the pressure. At this time, the motor 2 is turned off to cut off the output shaft power. Only radial force is applied against the outer ring 8. The static test of the oil-free bearing 7 can be carried out to determine the static radial torque value. The pressure plate 9 can be removed from the inner hole 14 by bolts 10 for disassembly. The cooperation between them greatly improves work efficiency.
