Description

Technical Field

[0001] This utility model relates to the field of torque sensor technology, specifically a non-contact torque sensor mounting device. Background Technology

[0002] Currently, non-contact torque sensors (disc torque sensors) play a crucial role in industrial measurement and scientific research. These sensors, with their unique working principle—measuring torque on a rotating shaft without physical contact—effectively avoid the frictional losses and measurement errors that can be introduced by traditional contact sensors, thus improving measurement accuracy and long-term stability. However, in practical applications, the installation and positioning of non-contact torque sensors has become a significant technical challenge, especially when they are required to be deployed in a horizontal manner.

[0003] Lateral mounting is a common application mode for non-contact torque sensors. It requires the sensor housing to be firmly fixed to the test bench via a precisely designed base, ensuring no displacement or shaking occurs throughout the measurement process. Simultaneously, the sensor's rotating disk must be precisely mounted on the rotation axis of the test specimen. This step is extremely critical because an absolute gap must be maintained between the rotating disk and the housing to achieve non-contact measurement. While this design cleverly avoids the wear problems caused by direct contact, it also places extremely high demands on the positioning accuracy during installation.

[0004] Because the rotating disk lacks a direct physical positioning mechanism relative to the outer casing, even slight deviations during installation can lead to significant errors in measurement results, or even cause the sensor to malfunction. To achieve precise alignment, technicians typically need to utilize high-precision positioning tools and equipment, such as laser alignment instruments and precision levels, to ensure the coaxiality and appropriate clearance between the rotating disk and the outer casing. This process is not only time-consuming and labor-intensive but also demands a high level of expertise from the operators, increasing both the cost and the technical barrier to entry.

[0005] Furthermore, the use of non-contact torque sensors also has certain limitations. For example, under certain extreme conditions, such as high temperature, high-speed rotation, or strong magnetic field environments, the performance of the sensor may be affected, leading to decreased measurement accuracy or unstable signal transmission. In addition, since non-contact measurement relies on principles such as electromagnetic induction and photoelectric effect, it may not be possible to achieve effective measurement for certain materials or surface conditions (such as poor conductivity and low reflectivity), thus limiting its application range.

[0006] Therefore, the high positioning requirements of non-contact torque sensors and their limitations in specific application scenarios remain problems that urgently need to be solved in the current technological development. Utility Model Content
