Description

Belt tearing detection device

Technical Field

The invention relates to the technical field of belt detection, in particular to a belt tearing detection device.

Background

The belt transmission is realized by using a tensioned (annular) belt which is sleeved on belt pulleys of two transmission shafts, and the power of one shaft is transmitted to the other shaft by virtue of the friction force generated when the belt and the belt pulleys are tensioned. The belt rotation can be used for large-distance transmission between two shafts (a working machine and a power machine). The belt has elasticity, so that impact can be relieved, vibration can be reduced, transmission is smooth, and a strict transmission ratio (the ratio of the revolutions per minute of the driving wheel to the revolutions per minute of the driven wheel) cannot be maintained. When the transmission part is in obstruction or overload, the belt can slip on the belt wheel, so that the machine parts can be prevented from being damaged. The belt transmission is simple and easy, the cost is low, the maintenance is simple, and the disassembly and the replacement are convenient. However, since the belt slips on the pulley, the mechanical efficiency of the belt transmission is low, and the durability of the belt itself is poor, and the belt gradually stretches after being used for a long time, and thus, the adjustment should be performed at any time.

The belt transmission consists of a driving wheel 1, a driven wheel 2 and an annular belt tensioned on two belt wheels; due to the tension, a pressing force is generated at the contact portion of the belt and the pulley. When the driving wheel runs, the belt is driven by the friction force, and the driven wheel is driven by the belt to run. Thus, the power of the driving shaft is transmitted to the driven shaft. The belt is connected in a loop and is looped over a pair of pulleys with a tension (referred to as tension) P0 to press the belt and pulleys against each other. When the belt is not in operation, the tension on both sides of the belt is equal (equal to R). When the belt works, the same friction force with the pulley surface increases the tension of one side of the belt, and reduces the tension of the other side of the belt. The difference P1-P2 between the two is the effective tension transmitted by the belt. It is numerically equal to the sum of the friction forces along the contact arc of either pulley. Under certain conditions, the friction force has a limit value, and if the working resistance exceeds the limit value, the belt slips on the wheel surface, so that the transmission cannot work smoothly. The limit of friction is determined by the belt material, the tension, the wrap angle (contact angle), the belt speed, and other factors. The greater the tension P0 and the wrap angle α 1 (the smaller of the two wrap angles), the greater the limit value of the friction force when the other conditions are the same. In order to effectively utilize the belt, it is necessary to properly control the tension and maintain an excessively small wrap angle. The latter requirement limits the minimum center distance and maximum transmission ratio of the belt drive

The detection of the belt is concerned with the normal operation of the equipment, and once the belt is broken, the safety of workers can be threatened, and the belt is very dangerous, so that the detection of the belt tearing is important, however, the detection of the belt tearing in the prior art generally detects an unused belt, the belt in use needs to be manually scanned, the speed is low, the efficiency is low, and the detection of the belt tearing in the prior art is not very good.
