Gear Speed Sensor Working Principle

In many mechanical devices, speed measurement is very important. For example, the engine speed of a car, the speed of a production line in a factory, etc., all need precise speed measurement to ensure the normal operation of the equipment. The gear speed sensor is a common speed measuring device, which measures the speed by measuring the rotation of the gear. So, what is the working principle of the gear speed sensor? How is it implemented? This article will explain in detail for you.

 

Firstly, we need to understand what a gear speed sensor is. A gear speed sensor is a device that uses the meshing relationship of gears to measure the speed of an object. Its working principle is: when one gear drives another gear to rotate, the ratio of the number of teeth of the two gears is the ratio of their rotational speeds. Therefore, as long as the number of teeth of the two gears is known, the speed of the object can be calculated by measuring their rotation times.

 

Next, let's look at how the gear speed sensor is implemented. The implementation of the gear speed sensor mainly relies on two parts: one is the gear, and the other is the counter.

 

1. Gear: The gear is the core part of the gear speed sensor, which transfers power to another gear and realizes speed measurement through the difference in tooth numbers. The size, shape, and number of teeth of the gear will affect the accuracy of speed measurement, so it needs to be very precise when designing and manufacturing the gear.

 

2. Counter: The counter is another important part of the gear speed sensor, which records the number of rotations of the gear. The working principle of the counter is that every time the gear rotates one circle, it will generate a pulse signal, and the counter will record it. By counting the number of pulse signals, the number of rotations of the gear can be obtained, and thus the speed of the object can be calculated.

 

In actual use, the gear speed sensor is usually installed on equipment that needs to measure speed, such as the engine of a car, a production line in a factory, etc. When the equipment runs, the gear speed sensor will start working, measuring the rotation times of the gear to calculate the speed of the equipment. If the speed of the equipment exceeds the set range, the gear speed sensor will issue an alarm to remind the operator to adjust the speed of the equipment in time.

 

In general, the working principle of the gear speed sensor is to calculate
