[0002] The belt smooth pulley is a hub-type part and is widely used in engines. It is mainly used to ensure that the belt wrap angle of the wheel train meets the occasions of transmitting power. In the process of fastening the smooth pulley to the fan shaft with bolts, a locking device is usually required to stop the fan shaft so as to tighten the bolt torque.

[0003] Existing locking devices usually use a complete product belt for friction locking, which has a small wrap angle and insufficient friction. Usually, a complete wheel system needs to be assembled before the locking device can work. The assembly sequence is high and it is time-consuming and labor-intensive. For engines that do not require belts to be installed before leaving the factory, there is also the disadvantage of multiple disassembly and assembly.

[0004] The disclosure of the above background technology content is only used to assist in understanding the concept and technical solution of the present invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Summary of the invention

[0005] The purpose of the present invention is to provide a smooth wheel stopping belt device and a method of using the same, so as to solve the technical problem in the above-mentioned prior art that a complete product belt must be used to install the entire wheel system before friction stopping can be performed.

[0006] To this end, the present invention provides a smooth wheel belt stopping device.

[0007] Preferably, the present invention may also have the following technical features:

[0008] A smooth wheel stopping belt device includes a belt and a first leather ring, both of which are closed-loop structures. The first leather ring is movably sleeved on the outside of the belt to divide the belt into a first part and a second part arranged on the left and right. At the first leather ring, the two outer walls of the belt abut against the inner walls of the first leather ring. The first part and the second part can respectively cooperate with the first smooth wheel and the second smooth wheel on the engine, and enable the belt to hold the second smooth wheel tightly to facilitate fastening the second smooth wheel to the fan shaft. The diameter of the second smooth wheel is larger than that of the first smooth wheel.

[0009] Preferably, the width of the first leather ring is one tenth of the diameter of the belt.

[0010] Preferably, two inner side walls of the belt are in contact with each other at the first leather loop.

[0011] Preferably, the belt is made of rubber and reinforcing material, and the reinforcing material is one or more combinations of cotton canvas, rayon, synthetic fiber or steel wire.

[0012] Preferably, it also includes a second leather ring, which is arranged on the left side of the first leather ring, is spaced apart from the first leather ring, and is movably mounted on the outside of the belt to divide the belt into the first part and the second part arranged on the left and right, and a third part located between the first leather ring and the second leather ring.

[0013] Preferably, the second leather ring can produce a certain deformation.

[0014] A method for using the above-mentioned smooth wheel belt stopping device comprises the following steps:

[0015] (1) Slip the first part of the belt onto the first smooth wheel of the engine, and slip the second part onto the second smooth wheel; (2) Use a tool to install bolts on the second smooth wheel, twist the tool to drive the second smooth wheel to twist clockwise by a small angle, and the twisting of the second smooth wheel drives the belt to rotate synchronously; (3) Continue to twist the tool to twist the second smooth wheel clockwise by 60°, so that the first leather ring at least partially contacts the surface of the second smooth wheel, the belt is partially folded and holds the second smooth wheel tightly, the first part is tightened, and the second leather ring is pulled and partially deformed, giving the first part a pre-tightening force; (4) Restore the folded part of the belt; (5) Repeat the above steps (2) to (4) until all bolts on the second smooth wheel are tightened.

[0016] Preferably, before step (2), the method further includes adjusting the first apron and the second apron to specified positions.

[0017] Preferably, step (4) includes using a tool to rotate the second smooth wheel at a small angle so that the folded portion thereof is restored.

[0018] The beneficial effects of the present invention compared with the prior art include: the present invention provides a smooth wheel belt stopping device, the belt is flattened, and the first leather ring is sleeved on the outside of the belt. When the device is used, the first part and the second part of the belt are correspondingly sleeved on the first smooth wheel and the second smooth wheel of the engine. When the second smooth wheel is tightened with bolts, the belt will be driven to twist until the belt hugs the second smooth wheel, and then the belt is loosened to restore its folded position. The above actions are repeated to tighten the bolts on the second smooth wheel. The device does not need to use a complete product belt to install the entire wheel system before friction locking. The belt used is not a complete product belt. The first smooth wheel closest to the second smooth wheel to be tightened with bolts can be selected, and a belt of suitable size can be selected based on the distance between them. Since the belt is short, a large wrap angle friction can be achieved during use, the locking effect is good, the operation is simple, and there is no need to install a complete wheel system. It is convenient to disassemble and assemble, saving labor time, improving work efficiency, and reducing the production cost of the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0025] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0026] Embodiment 1:

[0027] This embodiment provides a smooth wheel stop belt device, such as Figure 1 and 3As shown, it includes a belt 1 and a first leather ring 2, both of which are closed-loop structures. The first leather ring 2 is movably sleeved on the outside of the belt 1. It can be understood here that the belt 1 is flattened, and the first leather ring 2 is sleeved on the flattened belt 1. The first leather ring 2 divides the belt 1 into a first part 11 and a second part 12 arranged on the left and right. It can be understood that the width of the first leather ring 2 must be smaller than the diameter of the belt 1 so that the belt 1 can be divided into the first part 11 and the second part 12. Preferably, the width of the first leather ring 2 is one tenth of the diameter of the belt 1. At the first leather ring 2, the two outer side walls of the belt 1 abut against the inner side walls of the first leather ring 2, which means that the material of the belt 1 itself has a certain hardness and is not made of soft material. Preferably, the belt 1 is made of rubber and reinforcing material, and the reinforcing material is one or more combinations of cotton canvas, rayon, synthetic fiber or steel wire, so that the belt 1 itself has a certain tension, and there is outward tension at the place where it is sleeved by the first leather ring 2. The belt 1 with this structure can effectively prevent the first leather ring 2 from sliding freely and avoid affecting the use.

[0028] In some other examples of this embodiment, the two inner walls of the belt 1 are in contact at the first leather ring 2. It can be understood here that the height of the inner ring of the first leather ring 2 can just accommodate two layers of belts 1, that is, the flattened and stacked belts 1, which can make the entire device more compact and effectively improve the stopping effect of the belt 1.

[0029] When using the device, the first part 11 and the second part 12 can cooperate with the first smooth wheel 4 and the second smooth wheel 5 on the engine respectively, that is, the device is essentially a tooling, and finally can make the belt 1 hold the second smooth wheel 5 tightly, so as to facilitate the fastening of the second smooth wheel 5 to the fan shaft. It can be understood that the diameter of the second smooth wheel 5 is larger than that of the first smooth wheel 4, so that the device has a good stopping effect. The above device does not need to use a complete product belt to install the entire wheel system before friction stopping. The belt 1 used is not a complete product belt. The first smooth wheel 4 close to the second smooth wheel 5 to be tightened with the bolt 6 can be selected, and a belt 1 of a suitable size can be selected according to their distance. Even the company's existing idle or scrapped belt 1 can be shortened for use, and the connection can be made at the cut. Of course, when using it, it is necessary to try to avoid direct contact between the connection and the first smooth wheel 4 and the second smooth wheel 5 on the engine to avoid damaging the wheel surface at the connection. Since the belt 1 of the device is relatively short, a large wrap angle friction can be achieved during use, the stopping effect is good, the operation is simple, and there is no need to install a complete wheel system, so it is easy to disassemble and assemble, saving working hours, improving work efficiency, and reducing the production cost of the enterprise.

[0030] Embodiment 2:

[0031] The difference between this embodiment and the first embodiment is that Figure 3 and 4 As shown, it also includes a second leather ring 3, which is arranged on the left side of the first leather ring 2, with a spacing between the first leather ring 2 and the first leather ring 2, and is movably sleeved on the outside of the belt 1, so as to divide the belt 1 into the first part 11 and the second part 12 arranged on the left and right, and a third part 13 located between the first leather ring 2 and the second leather ring 3. Preferably, the second leather ring 3 can produce a certain deformation. When the device is used, the second leather ring 3 will hardly overlap with the second smooth wheel 5. It will be pulled away by the first part 11 of the belt 1 by a certain distance. Due to the reaction force, the second leather ring 3 will give a certain pre-tightening force to the first part 11 of the belt 1, so that the overall structure of the device is more stable and the belt 1 can be prevented from escaping from the first smooth wheel 4.

[0032] Embodiment three:

[0033] The present embodiment provides a method for using the above-mentioned smooth wheel stopping belt device, which comprises the following steps: (1) sleeve the first part 11 of the belt 1 onto the first smooth wheel 4 of the engine, and sleeve the second part 12 onto the second smooth wheel 5; (2) use a tool to install a bolt 6 on the second smooth wheel 5, twist the tool to drive the second smooth wheel 5 to twist clockwise at a small angle, and the twisting of the second smooth wheel 5 drives the belt 1 to rotate synchronously; (3) continue to twist the tool to twist the second smooth wheel 5 clockwise by 60°, so that the first leather ring 2 is at least partially in contact with the surface of the second smooth wheel 4, and the belt 1 is rotated. The belt 1 is partially folded and holds the second smooth wheel 4 tightly. The first part is tightened, and the second leather ring is pulled to be partially deformed, giving the first part a pre-tightening force. The partial folding mentioned above can be understood as the folding of the belt 1 and the second part 12 in the following situations: the part of the belt 1 wrapped by the first leather ring 2, or the belt 1 wrapped by the first leather ring 2 plus a small section of the third part 13, or the belt 1 wrapped by the first leather ring 2 plus the entire third part 13, but not including the belt 1 wrapped by the second leather ring 3; (4) restore the folded part of the belt 1; (5) repeat the above steps (2) to (4) until all the bolts 6 on the second smooth wheel 5 are tightened.

[0034] Specifically, before step (2), the first leather ring 2 and the second leather ring 3 may be adjusted to a specified position. The specified position here can be understood as when the second smooth wheel 5 is twisted clockwise by 60°, so that the first leather ring 2 at least partially contacts the surface of the second smooth wheel 5, the belt 1 is partially folded and holds the second smooth wheel 5 tightly, but the belt 1 wrapped by the second leather ring 3 does not contact the second smooth wheel 5. It can be determined according to the specific situation. When used to install a second smooth wheel 5 of the same size, the first leather ring 2 and the second leather ring 3 can be selected after multiple tests, and then marked and adjusted to the corresponding position each time. Specifically, step (4) includes using a tool to rotate the second smooth wheel 5 at a small angle so that its folded part is restored.

[0035] Those skilled in the art will appreciate that numerous variations to the above description are possible, and that the examples and figures are intended only to describe one or more specific implementations.

[0036] Although what is considered as exemplary embodiments of the present invention has been described and described, it will be understood by those skilled in the art that various changes and substitutions may be made thereto without departing from the spirit of the present invention. In addition, many modifications may be made to adapt specific situations to the teachings of the present invention without departing from the central concept of the present invention described herein. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but the present invention may also include all embodiments and their equivalents that fall within the scope of the present invention.
