Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a belt tension measuring device and a belt tension measuring method ', and in particular to a belt tension measuring device for easily adjusting a value to be measured And belt tension measurement method. [Prior art]

Belts are widely used in various types of machinery and equipment, including various types of vehicles, engines, and various factory automation equipment in operation. Regarding the common use of the belt, the belt is placed on the bearing, and the power of the motor is transmitted to the other end of the bearing. At this time, the belt is called a transmission belt.

The belt is usually made of an elastic material and uses its own tension to increase the friction between the belt and the bearing so that the bearing can drive the belt without idling. Therefore, when the belt is placed on the bearing, it must have considerable tension. However, too much tension can cause problems. For example, the bearing may be deformed or easily damaged. It may also cause problems with the motor connected to the bearing due to excessive force on the bearing in a specific direction. Therefore, measuring belt tension becomes a very important task. Moreover, because the belt will change its properties after long-term use, and then affect its tensile performance, measuring belt tension becomes a task that must be performed frequently. In the past, if you want to measure the belt tension, you must send the belt to the measurement worker. A tension meter for measuring the belt is installed in the measurement factory. However, the measuring instrument does not

V. Description of the invention (5) Reveal the meaning of mobile connection. First, as shown in FIG. 1 (a), the protruding portion 1011 of the detector 101 protrudes from the line direction 152 along the vehicle. The reference line 152 is projected to have a measurement distance 153. Next, as shown in FIG. 1 (b), the user does not need to change the shape of the elastic device 104. The relative position of the movable displacement adjusting device 1031 with respect to the base 1032, so the reference line 151 Moving along the axis 152, the measurement distance 1 5 3 is changed accordingly. In other words, 'Because the displacement adjustment device 1031 and the base 1032 are mobilely connected', when the user adjusts the relative position of the displacement adjustment device 1031 and the base 1032, the elastic device 104 can be unstressed. In the case of the sensor, adjust the value of the measurement distance 153 that the protrusion point 1011 protrudes along the axis 152. It must be pointed out that this example provides a schematic diagram of the structure. In practice, the displacement adjustment device 1031 and the base 1032 can be made into a flat shape, a cylindrical shape, or various deformations based on this topology. These deformations are all part of the present. The scope of the invention. As for the two wings 1001 and 1002 disclosed in this example, they can be designed separately or they can be combined, that is, the two wings 丨 〇 丨 and 丨 〇〇2 can be connected to each other to form one in appearance. Overall, here with two wings 1001

The description of the present invention with 1 0 2 is only for clearly showing the features of the present invention, and not for limiting the shape of the two wings 1001 :: 1002 or the connection relationship between the two wings. 1001 and 1002 can also be attached to a body (not shown) during implementation, and the body can be used to make the abutment device 100 and the displacement adjustment device 1031 including two wings 1001 and 1002. connection. Next, please refer to Figure 2 and Figure 3, where Figure 2 illustrates the first! Figure (3) shows the operation of the measuring device embodiment, and Figure 3 is the use of this measuring device

587161 V. Method flow chart of invention description (6). Continuation of FIG. 1 (a) measuring disclosed and instructions configured, first, the adjustment of the measuring device as described above (step 302). The adjustment here refers to changing the relative relationship between the displacement adjusting device 1031 and the base 1 032, so that the elastic device 1 042 makes the protruding portion ι 1 protrude from the reference line 151 in the direction of the aforementioned axis 152 without being stressed. — The predetermined measuring distance 153. This measurement distance 1 5 3 is a corresponding specification corresponding to the required belt tension. For example, suppose that the resistance force of the belt tension relative to the vertical direction (that is, the axis 152) is 10 kg, and the tolerance value is 1 kg, and the deformation distance of the elastic device 104 for the 10 kg along the axis 152 is 3 3cm。 At this time, I changed the relative relationship between the displacement adjustment device 1031 and the base 1 0 32, so that the measurement distance 153 is 3.3 cm. The two end points of the belt 102 to be measured 1 0 21 and 1 0 2 2 are arranged on the two bearings 1061 and 1062 in advance. Next, the two wings 1001 and 1002 of the measuring device 10 against the device 100a against the two end points 1021 and 1022 of the belt 102 (step 304), as shown in FIG. 2. That is, when the belt 10 is not stressed, one side is located on the reference line 151, but at this time, because the protruding portion 1011 abuts against the belt 丨 〇2, and the elastic device 104 connected thereto obtains the elastic force, the belt 10 102 exerts a force in the direction of the axis 152. In addition, since the belt 102 itself also has tension, it will also push the 4 protruding portion 1011 toward the elastic device 104, and when balanced, the protruding portion 1011 may protrude from the reference line 151-the force distance 154. At this time, by observing (for example, visually inspecting) the force receiving distance 154, it is possible to know whether the tension of the belt 102 meets the specifications (step 306). To more clearly explain the principle of this measurement 10 and its use, see

Page 10 587161

Figure 4 (a), Figure 4 (b), and Figure 4 (c). Figure 4 (a) shows a zero-to-zero measuring device. At this time, the measurement distance of the protruding portion 1011 along the axis 52 and the reference line 7 1 51 is 0. In order to measure a specific belt specification, including basic tension and tolerance, the following will adjust the relative distance between the displacement adjustment device 1031 and the base 1032 in two stages. First, the basic tension is converted into the basic tension displacement value 1531 of the relative elastic device 104, and then the relative distance between the displacement adjustment device 1031 and the base 1032 is adjusted so that the measurement distance 153 is the basic tension displacement value 1531. As shown in Figure 4 (b). Then 'reconvert the tolerance value to a tolerance displacement value of 1532, and adjust the relative distance between the displacement adjustment device 1 0 31 and the base 1 032, so that the measurement distance < 153 is the basic tension displacement value 1531 plus the tolerance displacement value 1 532, as shown in Figure 4 (c). Next, the adjusted measuring device 10 is pressed against the two wings 1001 and 1002 of the device 100 against the belt, respectively, and the force distance 54 is observed. With the force 154 from the tension of the belt under test have different performance values. For example, it may be greater than or equal to zero, but less than or equal to the aforementioned tolerance shift value 532, as shown in Figure 5 (a). Department of meaning at this time on behalf of the tested belt meets specifications.

Another case where a belt is too loose, this time as the presented measurement results of FIG. 5 (b), it was observed that the force has exceeded the distance 154 may be tolerable displacement value found in 1532. At this time, the belt is out of specification. There is also a case where the belt is too tight, and the measurement result presented at this time will be as shown in Fig. 5 (c) '. Observing the force distance 154, it can be found to be zero. Since the pre-positioned before displacement tolerance value 1532, and therefore, such a force by the distance 154 is still zero, represents the belt tight, the tension exceeds the tolerance value, it nor meet specifications.

In addition, the displacement adjustment device 5031 is composed of a first adjustment device 5011 and a second adjustment device 50312. The first adjustment device 50311 and the second adjustment device 50312 are connected in a socket manner, and the second adjustment device 50 312 is connected to the base 5032 in a socket connection manner, as shown in Fig. 5 (a) and Fig. 5 (b). ≪ With this connection method, the first adjusting device 50311 can be relatively The second adjustment device 50312 moves and adjusts, and at the same time, the second adjustment device 5012 can move and adjust relative to the base 5032. In this example, the first adjustment device 5〇 31ι is used to adjust the aforementioned basic tension displacement value, and the second adjustment device 50312 is used to adjust the aforementioned tolerance displacement value. In addition, a scale is also added to the adjuster 50. The first scale table 5051 is used to adjust the basic tension displacement. The second scale table 50 52 is used to adjust the tolerance displacement value, and the third scale table 5053 is for the user to visually measure the force distance after the belt.

In other words, with the measuring device 50 disclosed in the present invention, it is only necessary to first convert the required belt tension specifications into basic tension displacement values and tolerance displacement values, and then notify the belt measurement personnel. The belt measuring person adjusts the first adjusting device 50311 and the second adjusting device 50312 according to the instructed data. Then, as described above, the measuring device 50 is pressed against the belt, and the protruding portion 50 11 is visually protruded along the line from the reference line. The result of the line, you can simply and clearly know whether

It must be pointed out that, in this example, the whole device 50 3 1 1 for adjusting the basic tension value is connected to the second adjustment device 5012, and the second device 503 1 2 is connected to the base 5032. However, the present invention naturally covers the case where the adjusting device 503 11 is interchanged with the second adjusting device 5012. In addition, the various elements of the socket of the foregoing are within the scope of the present invention. Furthermore, the previously cited 10 and measuring gauges for 5〇 only described with the present invention, not to limit the present invention. Therefore, the reverse of the elastic device, as shown in Figure 7 (a), and related changes, as long as it does not deviate from the topology of the invention, is also within the scope of the present invention. In addition, with the advancement of electronic technology, adjustment and measurement results can also be provided to measurement personnel through a display.
