specific Embodiment approach 1

[0013] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment. A flywheel with a noise reduction structure described in this embodiment is composed of a hub 1, a spoke 2, and a rim 3. This embodiment also includes a plurality of shape memory alloy blocks 4. Both sides of the rim 3 A plurality of grooves 3-1 are evenly distributed along the circumferential direction, and a shape memory alloy block 4 is respectively installed in each groove 3-1.

[0014] In this embodiment, due to the low rigidity of the shape memory alloy block 4, the shape memory alloy block 4 has relatively large elasticity after deformation, and can always maintain close contact with the inner wall of the groove 3-1. Due to the elastic deformation of the shape memory alloy block 4 The ratio can reach more than 8%. When the shape memory alloy block 4 is worn out, it can still maintain close contact with the inner wall of the groove 3-1 by relying on its own recoverable elasti...

specific Embodiment approach 2

[0015] Specific implementation mode two: combination Figure 1 to Figure 4 To illustrate this embodiment, each shape memory alloy block 4 of a flywheel with a noise reduction structure described in this embodiment is installed in the groove 3 - 1 by a screw 5 . Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0016] Specific implementation mode three: combination Figure 1 to Figure 4 To describe this embodiment, each screw 5 of a flywheel with a noise reduction structure described in this embodiment is a self-locking screw.

[0017] The technical effect of this embodiment is: so set, the shape memory alloy block 4 is fixed in the groove 3-1 with the self-locking screw, which can prevent the shape memory alloy block 4 from falling off from the groove 3-1 during the rotation of the flywheel. Other components and connections are the same as those in the second embodiment.

Abstract

The invention relates to a flywheel, in particular to a flywheel with a noise reduction structure and belongs to the field of mechanical drive. The flywheel aims at solving the problems that strong noise and vibration generated during rotation of a flywheel affect the service life of mechanical equipment, damage instruments and harm the physical health of a user. The flywheel is composed of a hub, a spoke and a rim. The flywheel further comprises multiple shape memory alloy blocks. Multiple grooves are evenly distributed in the two sides of the rim in the circumferential direction. Each groove is internally provided with one shape memory alloy block.

Description

technical field [0001] The invention relates to a flywheel, in particular to a flywheel with a noise reduction structure, which belongs to the field of mechanical transmission. Background technique [0002] In the shafting structure, rolling bearings are widely used in modern industry due to their small frictional resistance, high transmission efficiency, and compact structure. They are key components in rotating machinery and are also the main cause of flywheel vibration and noise. It is mainly manifested in the following aspects: 1. The waviness of the bearing surface. The surface waviness is a surface roughness composed of random or near-periodic components whose spacing is much larger than the roughness. It can be seen from the definition that surface waviness is the surface geometric roughness between microscopic geometric roughness, surface roughness and macroscopic geometric roughness, surface geometry, straightness, roundness, and flatness. It is mainly used in machi...
