AI Technical Summary
Existing low-noise saw blades have limited noise reduction effects during cutting and cannot effectively reduce noise generated by high-speed rotation and vibration, which can cause harm to the human body.
An installation cavity is opened on the saw blade body and filled with a rubber block. The rubber block absorbs vibration waves to reduce noise, and the noise is further reduced by combining it with a sound-absorbing hole structure.
It effectively absorbs the vibration waves from the high-speed rotation of the saw blade, significantly reducing noise and improving the noise reduction performance of the saw blade.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of saw blade technology, and in particular to a low-noise saw blade. Background Technology
[0002] Saw blades generate noise during the cutting process, which can cause various forms of harm to the human body, and even lead to hearing loss in workers during prolonged use. Existing low-noise saw blades reduce noise by having sound-absorbing holes on the blade. Although these holes can reduce some noise, the high speed and vibration of the saw blade during operation mean that the sound-absorbing holes alone have a limited effect on noise reduction, and there is still considerable noise that can harm the human body.

[0006] The beneficial effects of this utility model are: by opening an installation cavity on the saw blade body and filling the installation cavity with a rubber block, the rigid saw blade material is replaced with soft rubber, which can effectively absorb the vibration waves generated by the vibration of the saw blade body during high-speed rotation, thereby effectively reducing the noise of the saw blade body.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, the mounting cavity is fan-shaped and arranged in an array with the mounting hole as the center.
[0009] The further beneficial effect of adopting the above is that the rubber blocks are arranged in a ring, which absorbs the vibration waves of the saw blade body from all directions, thereby further improving the noise reduction performance of the saw blade body.
[0010] Furthermore, a first noise-reducing hole communicating with the saw tooth gap is provided on the saw blade body corresponding to each saw tooth gap.
[0011] Furthermore, it also includes a second silencing hole, which is formed through the fixing plate and the saw blade body.
[0012] Furthermore, the saw blade body is provided with limiting posts on both the front and rear sides, and the front of the fixing plate is provided with limiting holes that are adapted to the limiting posts. The limiting posts are slidably sleeved inside the limiting holes.
[0013] Furthermore, it also includes a bolt, and the top of the limiting post is provided with a threaded hole that matches the bolt. The limiting hole is a countersunk hole that is adapted to the bolt.
[0014] Furthermore, the fixing plate has multiple third noise-absorbing holes corresponding to the rubber block. Attached Figure Description
