Description

Technical Field

[0001] The utility model relates to the technical field of flywheels, in particular to a long-life general-purpose flywheel. Background Art

[0002] A flywheel is a rotating object with a large moment of inertia. It stores mechanical energy in the rotational motion of the flywheel, thereby storing and releasing power. The flywheel in a general machine usually consists of a high-speed rotating shaft and a group of discs connected to it. When the external input power acts on the flywheel, the flywheel begins to accelerate and store energy. When the energy needs to be released, the speed is transmitted to other devices through a transmission device connected to the flywheel, thereby achieving the output of work. For example, the patent with announcement number CN220320206U discloses a general machine flywheel with a long service life. The anti-breakage reinforcement disc rotates with the main body of the general machine flywheel. During the rotation process, the anti-breakage reinforcement disc can be simultaneously subjected to force to help offset the stress generated on the main body of the general machine flywheel, preventing the main body of the general machine flywheel from cracking and damage. The above technical solution strengthens the stability of the flywheel main structure by the anti-breakage reinforcement disc. However, the flywheel is driven by a rotating shaft, and the rotating shaft drives each disc body to rotate. After a certain period of use, wear will occur between the disc bodies, resulting in the need to replace the disc body, affecting the service life. Utility Model Content

[0017] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0018] like Figures 1 to 3As shown, a long-life general-purpose flywheel of this embodiment includes a main body 1 and a connecting assembly 2. The main body 1 is arranged on the connecting assembly 2, and the main body 1 is connected to the rotating shaft through the connecting assembly 2. The connecting assembly 2 includes a connecting portion 3, a matching plate 4, a positioning ring 5 and a snap ring 6. The connecting portion 3 includes a plate body 31 and an extension portion 32 arranged on one end surface of the plate body 31. The plate body 31 has at least two groups of slots 33, each group of slots 33 has a different width, and the slots 33 are arranged around the circumference of the plate body 31. The extension portion 32 is provided with an annular groove 321 corresponding to the snap ring 6. The two end surfaces of the matching plate 4 are respectively provided with a first block 41 and a second block 42, and the number of the first blocks 41 is consistent with the number of each group of slots 33. The matching plate 4 is sleeved on the extension portion 32 through a perforation 43, and the first block 41 is inserted into the slot 33 from the side, so that the connecting portion 3 and the matching plate 4 can rotate synchronously. The positioning ring 5 is sleeved on the extension part 32. The positioning ring 5 has a notch 51. The notch 51 is arranged corresponding to the second clamping block 42, so that the adapter plate 4 can drive the positioning ring 5 to move. The main body 1 is connected to the positioning ring 5, so that the main body 1 can rotate. The clamping ring 6 is arranged on one side of the positioning ring 5 and presses the positioning ring 5. The positioning ring 5 is limited by the clamping ring 6, so that the connecting assembly 2 and the main body 1 become one. In the above technical solution, the adapter plate 4 and the positioning ring 5 are driven to rotate by the connecting part 3. After a certain period of use, the wear between the connecting part 3 and the adapter plate 4 will cause the first clamping block 41 and the card slot 33 to wear. By matching the first clamping block 41 with another group of card slots 33, the stability of the clamping can be maintained, thereby extending the service life of the flywheel.

[0019] In this embodiment, the connecting portion 3 includes a first slot group 34 and a second slot group 35. The first slot group 34 includes two first slots 331, and the second slot group 35 includes two second slots 332. The width of the first slot 331 is greater than the width of the second slot 332. First, the first card block 41 is matched with the first slot group 34. After a certain period of use, the first card block 41 is matched with the second slot group 34. Since the width of the second slot 332 is small, the first card block 41 can be firmly connected with the second slot 332 after being worn. The first slot 34 and the second slot 35 are arranged at intervals, and the two first slots 331 are symmetrically arranged, and the two second slots 332 are symmetrically arranged, so that the force is more uniform. The disk body 31 has an axial hole 311 in the middle, the first clamping slot 31 and the second clamping slot 332 are arranged around the axial hole 311, and a notch 312 is arranged in one side of the axial hole 311, so that the rotating shaft and the axial hole 311 can be connected by an existing key, so that the rotating shaft can drive the connecting part 3 to rotate. The disk body 31 has arc segments 313, and the opening 333 of the clamping slot 33 is located between the arc segments 313, so that the depth of the clamping slot can be increased and the contact area can be improved.

[0020] In this embodiment, the clamping ring 6 includes a clamping arm 61, and a notch 62 is provided on the clamping arm 61, so that the clamping arm 61 can expand or contract, and is convenient for clamping with the annular groove 321, and is convenient for installation and removal of the clamping ring 6. The first clamping block 41 and the second clamping block 42 are arranged alternately, that is, the first clamping block 41 and the second clamping block 42 are located at different positions. There are two first clamping blocks 41 and two second clamping blocks 42, and there are two notches 51, so that the torque can be stably transmitted.

[0021] A long-life general-purpose flywheel of the present embodiment can replace the clamping position after the clamping block is worn, thereby maintaining the clamping stability, improving the transmission stability, and extending the service life.

[0022] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
