Description

Technical Field

[0001] The invention relates to an intelligent module assembly structure of a transmission shaft. Background Art

[0002] Intelligence and wireless are the development direction of mechanical transmission shaft products and are the core technical means to realize the automation and intelligence of rotating equipment.

[0003] Drive shafts in the metallurgical industry are core components of production lines. Their operating accuracy and service life directly impact production output and quality. Therefore, during operation, relevant physical quantities (including torque, displacement, angle, temperature, and stress) must be monitored in real time, with sensors transmitting these parameters to a monitoring system. Currently, drive shaft monitoring is accomplished by attaching sensors to the shaft's outer diameter, which rotates synchronously with the shaft. However, this approach has several drawbacks: 1. Centrifugal forces can easily cause the attached sensors to fall off the shaft's outer diameter, resulting in unreliable data transmission and a risk of damage. 2. The sensor's harsh operating environment, often involving high temperatures and even cooling water, severely impacts the sensor's data reading quality and lifespan, which directly impacts the determination of the drive shaft's performance. 3. The sensor requires power to operate, which is impossible with an external charging cable or rotating machinery, and requires frequent recharging with a small internal rechargeable battery.

[0020] The intelligent module assembly structure of the present invention is positioned in the middle of the drive shaft, with flanges connecting the two ends to the drive shaft and rotating synchronously with the shaft. The double flange 1 serves as the drive shaft's intelligent compartment. The inner hole of the double flange 1 forms a sealed protective cavity through the left and right sealing end caps 4 and 5.

The fixed long screw 11 connects the right cover 32, the left cover 31, and the left sealing end cover 4, and the cylindrical battery pack 2 is fixed inside the left cover 31 and the right cover 32.

[0022] Specifically, the outer circle of the cylindrical battery pack 2 fits with the inner holes of the left cover 31 and the right cover 32 , with its left end pressed tightly against the inner end surface of the left cover 31 and its right end pressed tightly against the inner end surface of the right cover 32 .

[0023] The split structure of the battery fixing cover 3 securely fixes the cylindrical battery pack 2 , thereby achieving both a packaging effect and ensuring synchronous transmission between the battery pack 2 and the transmission shaft.

[0024] The contact surface between the left cover 31 and the right cover 32 is a stepped surface, and a gap is provided between the inner steps. The stepped surface and the inner step gap are used to ensure that the cylindrical battery pack 2 can be securely fixed. Example 3

[0032] Due to limited space inside the duplex flange 1 and to facilitate maintenance, some sensors need to be installed externally. External sensors 15 utilize a battery pack for continuous power supply over a long battery life. They transmit physical measurements related to the drive shaft's operation to the wireless transceiver module 7, which then transmits and receives these signals via the patch antenna 13.
