Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor speed monitoring technology, and relates to a shielded motor speed real-time monitoring device. Background Technology
[0002] While existing motor speed monitoring technologies are relatively mature, they still have some drawbacks. Traditional speed monitoring methods, such as those using mechanical tachometers or analog sensors, suffer from limited accuracy and reliability, and are susceptible to mechanical wear, vibration, and temperature variations. These drawbacks primarily arise because mechanical monitoring equipment relies on physical contact or specific environmental conditions, which are often difficult to maintain consistently in industrial applications. Analog signals are also prone to electromagnetic interference during transmission, leading to signal distortion and affecting the accuracy of the monitoring results.
[0003] Conventional solutions include using digital sensors and employing anti-interference techniques. Digital sensors improve accuracy and reliability by converting analog signals into digital signals, while also facilitating long-distance signal transmission and processing. However, these methods suffer from high costs, and the performance of digital sensors may be affected in certain extreme environments. Therefore, there is an urgent need for a shielded motor speed real-time monitoring device to address these issues. Utility Model Content

[0006] Several sets of constant speed plates are evenly distributed on the outside of the rear connecting rod.

[0007] In a preferred embodiment, each set of speed sensors is provided with an external drive module for driving and controlling them. The external drive module is matched with the speed sensor model. When the operator uses the motor, the motor drives the rotor to rotate. During the rotor rotation, the rotating shaft, drive rod, and rear connecting rod rotate synchronously. During the rotation of the rear connecting rod, several sets of constant speed plates rotate uniformly. At the same time, the two sets of speed sensors arranged on the same longitudinal line can detect the rotation speed of several sets of constant speed plates.

[0011] In a preferred embodiment, the two sets of outer clamping blocks are provided with a set of rear connecting frames on the right side for supporting the rear connecting rod. A set of connecting holes for positioning and fixing is provided between the rear connecting frames and the outer clamping blocks. When the motor is running, the outer clamping blocks and the outer positioning insert can quickly disassemble and install the outer positioning insert to ensure the stability of the stator. At the same time, the rear connecting frame can limit the rotational stability of the rear connecting rod, thereby improving the durability of the motor.
[0012] In a preferred embodiment, an external bolt passes through the connecting hole to connect and fix the rear connecting frame to the outer clamping block. A set of limit bearings for maintaining its limited rotation is provided on the outer side of the right end of the rear connecting rod. The rear connecting rod, the drive rod, and the rotating shaft are an integral structure.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by using a motor to drive the rotor to rotate, the rotor rotates and drives the shaft, drive rod and rear connecting rod to rotate synchronously during the rotation of the rotor. During the rotation of the rear connecting rod, it drives several sets of constant speed plates to rotate evenly. At the same time, two sets of speed sensors set on the same longitudinal line can detect the rotation speed of several sets of constant speed plates. Meanwhile, the limit bearing can limit the stability of the rotation of the rear connecting rod, thereby improving the accuracy of motor speed monitoring.
[0014] During motor operation, the outer clamping block and outer positioning insert can quickly disassemble and install the outer positioning insert to ensure the stability of the stator. At the same time, the rear connecting bracket can limit the rotational stability of the rear connecting rod, thereby improving the durability of the motor. Attached Figure Description
