Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine flywheels, in particular to a detachable single-cylinder diesel engine flywheel. Background Art

[0002] In the process of some mechanical actions, some related structures need to be used for coordination. For example, the operation of a single-cylinder diesel engine requires the coordination of a flywheel to achieve the smooth operation of the single-cylinder diesel engine. The installation of the flywheel requires the coordination of the center shaft, flywheel disc, bolts and other structures. The flywheel is fixed by aligning the position of the center shaft and the flywheel and turning the bolts.

[0003] However, when installing or disassembling the flywheel, it is necessary to rotate the bolts to complete the related work, which consumes a lot of time and makes the disassembly work inefficient. The gear ring and the main body on the outer surface of the existing flywheel are an integrated structure. After long-term use, the gears of the flywheel may be worn and damaged, which is inconvenient to disassemble and replace. Utility Model Content

[0026] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0027] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] Embodiment 1

[0029] like Figures 1 to 4 As shown, a detachable single-cylinder diesel engine flywheel includes a main body 1, which is disc-shaped. A fan-shaped through groove 3 is provided on the surface of the main body 1 to reduce the weight of the main body 1 and install a connecting structure 4. The connecting structure 4 is installed inside the through groove 3. A through hole is provided at the center of the main body 1, a ball groove 8 is provided inside the through hole, a positioning groove 9 is provided on one side of the ball groove 8, and four groups of ball grooves 8 and positioning grooves 9 are evenly arranged in a circular array inside the through hole.

[0030] The central axis 5 is located at the central through hole of the main body 1. A positioning block 6 is installed on the surface of the central axis 5. A snap-in ball 7 is installed on one side of the positioning block 6. There are four positioning blocks 6 and snap-in balls 7 in a uniform array on the surface of the central axis 5. The positioning block 6 is inserted into the positioning groove 9 for positioning during installation.

[0031] The card-engaging ball 7 is inserted into the ball groove 8, and a fixing block 16 is installed inside the central axis 5. Springs 2 17 are installed at four ends of the fixing block 16. The other end of the spring 2 17 is fixedly connected to one end of the card-engaging ball 7. The card-engaging ball 7 can slide on the surface of the central axis 5, and the central axis 5 is connected to the inside of the through hole. The positioning block 6 and the positioning groove 9 are aligned and inserted into the central axis 5. The surface of the card-engaging ball 7 contacts with the inside of the through hole and is squeezed, so that the card-engaging ball 7 slides toward the inside of the central axis 5, compressing the spring 2 17 until the card-engaging ball 7 moves to the ball groove 8. The spring 2 17 is restored, and the card-engaging ball is inserted into the ball groove 8, thereby fixing the main body 1 and the central axis 5.

[0032] During the use of the flywheel, the flywheel rotates, and inertia causes the spring 2 17 to tend to stretch outward, so that the clamping ball 7 will not be separated from the ball groove 8, and the main body 1 will not be separated from the central axis 5. When disassembly is required, the central axis 5 is fixed, and the main body 1 is moved to one end. The surface of the clamping ball 7 is squeezed, thereby compressing the spring 2 17, and the clamping ball 7 slides toward the inside of the central axis 5, and the clamping ball 7 is separated from the ball groove 8, thereby separating the main body 1 and the central axis 5.

[0033] The gear ring 2 is sleeved on the outer end of the main body 1, and an arc-shaped through groove 18 is provided on the surface of the gear ring 2 to reduce the weight of the gear ring 2. The gear ring 2 is fixed by a connecting structure 4, and the connecting structure 4 includes a fixed column 10, and the fixed column 10 is fixedly installed inside the fan-shaped through groove 3. The insertion rod 11 is slidably installed inside the fixed column 10, and a pull ring 12 is installed at one end of the insertion rod 11 to facilitate pulling the pull ring 12. The movable plate 13 is sleeved on the surface of the insertion rod 11, and the movable plate 13 can slide inside the fixed column 10. A spring 14 is sleeved on the surface of the insertion rod 11, and the spring 14 is located between the movable plate 13 and the fixed column 10. A slot 15 is provided inside the gear ring 2, and one end of the insertion rod 11 passes through the main body 1 and is inserted into the slot 15.

[0034] Pulling the pull ring 12 drives the insertion rod 11 to move. At the same time, the insertion rod 11 compresses the spring 14 through the movable plate 13, and the ring gear 2 is sleeved on the circumferential surface of the main body 1. The pull ring 12 is released, and the spring 14 is restored, so that the insertion rod 11 is inserted into the slot 15. When the ring gear 2 needs to be removed, the pull ring 12 is pulled to make the insertion rod 11 disengage from the slot 15.

[0035] Embodiment 2

[0036] It is described on the basis of Example 1. During installation, first pull the pull ring 12 to drive the insertion rod 11 to move. At the same time, the insertion rod 11 compresses the spring 14 through the movable plate 13, and the ring gear 2 is sleeved on the circumferential surface of the main body 1. The pull ring 12 is loosened, and the spring 14 is restored, so that the insertion rod 11 is inserted into the slot 15, and the fixation of the main body 1 and the ring gear 2 is completed. The center axis 5 is connected to the inside of the through hole, and the positioning block 6 and the positioning groove 9 are aligned with the center axis 5 and inserted. The surface of the snap-in ball 7 contacts with the inside of the through hole and is squeezed, so that the snap-in ball 7 slides toward the inside of the center axis 5, compressing the spring 2 17 until the snap-in ball 7 moves to the ball groove 8, and the spring 2 17 is restored, and the snap-in ball is inserted into the ball groove 8, thereby fixing the main body 1 and the center axis 5.

[0037] When disassembly is required, fix the central axis 5 and move the main body 1 to one end. The surface of the snap-in ball 7 is squeezed, thereby compressing the spring 2 17, and the snap-in ball 7 slides toward the inside of the central axis 5. The snap-in ball 7 disengages from the ball groove 8, thereby separating the main body 1 and the central axis 5. Pull the pull ring 12 to disengage the insertion rod 11 from the slot 15, and the main body 1 and the ring gear 2 can be disassembled, making it convenient to replace the ring gear 2.

[0038] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
