Description

Technical Field

[0001] The invention belongs to the technical field of torque sensors and relates to a non-contact torque sensor installation device. Background Art

[0002] Currently, non-contact torque sensors (disc torque sensors) play a vital role in industrial measurement and scientific research. This type of sensor has a unique working principle, that is, it can measure the torque on the rotating shaft without physical contact, effectively avoiding the friction loss and measurement error that may be introduced by traditional contact sensors, thereby improving the measurement accuracy and long-term stability. However, in practical applications, the installation and positioning of non-contact torque sensors has become a technical challenge that cannot be ignored, especially when they are required to be deployed in a horizontal installation manner.

[0003] Horizontal installation is a common application mode of non-contact torque sensors. It requires the housing of the sensor to be firmly fixed on the test bench through a precisely designed base to ensure that no displacement or shaking occurs during the entire measurement process. At the same time, the rotating disk of the sensor must be accurately installed on the rotating axis of the tested product. This step is extremely critical because an absolute gap must be maintained between the rotating disk and the housing to achieve non-contact measurement. Although this design cleverly avoids the wear problem caused by direct contact, it also places extremely high requirements on the positioning accuracy during the installation process.

[0004] Since there is no direct physical positioning mechanism for the rotating disk relative to the housing, a slight deviation during installation may lead to significant errors in the measurement results, or even cause the sensor to malfunction. In order to achieve precise alignment, technicians usually need to use high-precision positioning tools and equipment, such as laser plummets, precision levels, etc., to ensure the coaxiality and appropriate gap size between the rotating disk and the housing. This process is not only time-consuming and labor-intensive, but also has strict requirements on the professional skills of the operator, increasing the cost of use and technical threshold.

[0005] In addition, the use of non-contact torque sensors still has certain limitations. For example, in certain extreme working conditions, such as high temperature, high-speed rotation or strong magnetic field environment, the performance of the sensor may be affected, resulting in reduced 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 objects with certain specific materials or surface conditions (such as poor conductivity and low reflectivity), thus limiting its scope of application.

[0006] Therefore, the high positioning requirements of non-contact torque sensors and their limitations in specific application scenarios are still issues that need to be urgently addressed in current technological development. Summary of the invention
