Description of the invention (1) TECHNICAL FIELD The present invention relates to belt wear detection 'specifically' The method and device disclosed by the present invention are directed to spiral offset gear teeth Detection of Early Warning Wear of Belts β The method disclosed in the present invention is very useful for determining the early wear of timing belts for wheels. Background of the Art The conventional synchronous transmission belt has its gear teeth placed at a right angle to the straight line of the tangent line around the center of the belt. Such belts are well illustrated in U.S. Patent Nos. 4,108,011 and 4,690,664. In these known prior art belts, the tidy gear teeth are mouthed into the recesses of the corresponding pulleys at the same time. When this type of belt wears, the belt will start to swing on one side of the pulley to the other. In order to prevent the belt from swinging out of the drive system, the belt pulleys on the system are provided with flanges. "The wear of this belt is determined by visual inspection of the belt for cracks or breaks" or complete failure.

Meigu Patent No. 5,209,705 discloses a synchronous transmission belt with at least two rows of lateral abutting teeth, which has a centerline and is uniformly divided in the longitudinal direction by a length of one pitch and inclined in the longitudinal direction. The teeth in the lateral disengagement rows are at opposite balanced angles and the center lines of the adjacent teeth are offset from each other by a distance of 10% to 90% of the pitch length. This type of belt is called shorthand in shorthand terms Offset tooth (HOT) belt β Due to the structure of the teeth, the HOT belt is an automatic tracking belt. This means that there is no normal belt swing when the belt is running. Associated pulleys that respond to this shape of belt do not have flanges. Other known forms of automatic tracking belts are non-offset toothed belts ’

Description of the invention (2) which has at least two rows of horizontally adjacent The connected gear teeth and gear teeth have an extension centerline inclined to the longitudinal direction. This belt has a herringbone-shaped gear. The pulley connected to the herringbone gear belt also does not need flanges because the belt does not swing. The newly disclosed system is directed to the use of a timing belt alarm system. This alarm system is also a multi-stage alarm system. The disclosed invention can be used in any synchronous automatic tracking belts such as HOT belts and herringbone belts, and has great applicability to timing belts of motor vehicles. . 〇 At present, each vehicle engine has a certain time mechanism, which is a certain time belt or a timing chain to operate the engine. When the timing mechanism wears out, a complete failure of the mechanism will cause permanent damage to the engine 'or, in the best case,' the driver of the car will be helpless. For timing belts, there is no system or method for automatic detection of wear, so it is only possible to perform general inspections and is not completely correct. As a serious consequence in the event of a failure ', one preventative measure is to automatically change the belt every 60,000 miles. The other traditional method to prevent this kind of serious damage is to use a certain time chain instead of a belt " timing baht, long before the thinning occurs, to make noise to warn the driver of the timing chain problem and replace the fixed chain. However, the timing chain is heavy and the entire system is more expensive than a belt drive system. The present invention has a more timely evaluation of the replacement of the timing belt of the engine and does not rely on the artificial evaluation of the belt incorrectly, and 1 can enable the vehicle manufacturer to use a more lightweight, lightweight belt drive system. Today's invention results in fewer belt changes β Summary of the invention The object of the present invention is an improvement for a synchronous automatic tracking belt

Description of the invention (4) 2 gear teeth 4 belt pulley CL centerline 1 belt 3 wear 5 sensor M deviation is better Detailed description of the embodiment As excerpted above and shown in FIG. 1, a HOT belt 1 has two rows of laterally adjacent teeth 2 which are uniformly spaced in the longitudinal direction L and extended as a dump. The teeth 2 in two laterally adjacent rows make opposing angles with respect to the belt centerline CL. In the transmission system of a belt, the belt is mounted on at least one pulley. In the automatic zigzag wheel #belt, such as the tooth 2 in FIG. 1, it is a herringbone shape, that is, in The teeth 2 in adjacent rows will not be offset from each other. The following discussion is directed to the HOT belt 1 illustrated in the illustration, but it can be equally applied to the automatic tracking herringbone belt. ϋ It has been determined that when the automatic belt is worn, as shown in 蔺 2, the wear of the teeth of two adjacent tooth rows is asymmetric. That is, the tooth 2 on the side of the center line CL of the platoon shows the wear of W3 is greater than the wear of the tooth on the opposite side of the center line CL because the belt 1 is automatically tracked, and because the tooth 1 and its corresponding The outer shape of the pulley (refer to U.S. Patent No. 5,209,70 5) 'When a pair of gear teeth wear, the belt 1 will break off its t-line, which will cause a permanent deviation M of the belt 1 on a pulley. This deviation is proportional to the amount of wear 3 of the belt 1. The deviation M of the belt 1 is very advantageous to provide a wear indicating system for the belt 1. This system can be illustrated in a very simple way in Figure 3 with a circled solution. The belt 2 mounted on the pulley 4 is closed on the pulley by the tooth of the belt pulley.

A sensor 5 is mounted on the edge of the alignment belt 1 or the pulley 4. The sensor 5 can be any type of traditional sensor, from a simple optical or mechanical device that can detect the belt in front of or behind the sensor when it contacts or crosses to a more complex system using laser Relative displacement in direction. The primary condition of the sensor 5 is on the belt 1. When the sensor detects that the gap between the edge of the belt and the sensor increases or decreases, the sensor will operate, and the sensor will send an electric or acoustic signal to Make the belt change its position. The system can be installed on a single side using a single sensor, or many sensors can be installed on only one side for use in the multi-level warning system described below. The sensor mounted on one side can be used on the laser system described previously. In addition, if it is known that the belt track is worn on that side of the pulley, a single sensor can be installed on the side of the pulley. In order to achieve the known tracking pattern, one side of the belt, relative to the centerline, has a larger width than the other half of the belt. Figure 4 is a diagram illustrating the operation of the system, which illustrates that there is only one moving sensor. Because the belt 1 is worn, one side of the belt 1 shows greater wear than the other 3, and the belt 1 starts to move along the belt. One side moves more favorably than the other side, which causes a deviation of ti. When the belt 1 starts to move over one side of the pulley 4, the sensor 5 is activated. The sensor 5 sends an electrical or audible signal to indicate a deviation. The electrical signal is sent to a warning system to notify the operator of the timing belt wear. If the sensor is connected to the automatic timing belt, the electrical signal Can be applied to this system. Figures 3 and 4 illustrate a very simple one-stage warning system. The illustrated warning system can be equipped with more sensors on the pulley 4 or the belt 1.

When using more than two sensors, a two-stage warning system can be generated. The first sensor facing axially inward can trigger an initial wear warning, however, the sensor facing axially outward can trigger a warning of further or imminent failure of the belt.
