Embodiment Construction
[0014] Such as figure 1 , figure 2 and image 3 As shown, a vibration-reducing and noise-reducing circular saw blade is composed of a saw blade base 1, a ring gear 2, a streamlined groove 3, a rectangular groove 4, a composite damping material 5, a mounting hole 6 and a shaft hole 7, and the saw blade Substrate 1 is two circular steel plates made of 8CrV high-quality tool steel. Elastic modulus E=206GPa, Poisson's ratio γ=0.3, density ρ=7800kg / m 3 , The clamp diameter ratio of the circular saw blade is 0.3-0.6. Composite damping material 5 is sandwiched between two circular steel plates to form a "sandwich" structure. The thickness of the composite damping material 5 is less than or equal to 0.3t mm. The composite damping material 5 is made of steel wire mesh 8 and filled silicon rubber 9. The steel wire mesh 8 is the skeleton, and the steel wire mesh 8 is braided by steel wires with a diameter of 0.3 to 1 mm. , forming a rhombus or rectangular mesh, filled with silicon...

The invention discloses a vibration-reduction and noise-reduction circular saw blade, which can greatly reduce vibration and noise, improve work efficiency and work environment. The vibration-reducing and noise-reducing circular saw blade includes: a saw blade base, a ring gear, a streamlined groove, a rectangular groove, a composite damping material, a mounting hole and a shaft hole. The saw blade base is two circular steel plates, and two circular The composite damping material is sandwiched between the circular steel plates, and a ring gear is welded on the edge of two circular steel plates. The positions of the streamlined groove and the rectangular groove are staggered, and the sawtooth is processed on the ring gear. The invention has the effect of reducing vibration and noise on the basis of satisfying the bearing capacity. The noise experiment shows that the total sound pressure level of the noise of the vibration-reducing and noise-reducing circular saw blade under the same working conditions is higher than that of ordinary circular saw blades. About 20dB lower, achieved the purpose of improving the environment.
Description
technical field [0001] The invention relates to a tool for cutting metal and non-metal materials, in particular to a circular saw blade with vibration and noise reduction. Background technique [0002] In wood industry, metallurgy, marble, concrete and other raw material cutting industries, circular saw blades are widely used because of their good cutting performance and high processing efficiency. The metallurgical circular saw blade will rotate at high speed under the action of working conditions, and the vibration it receives is relatively large, and because of its large area and poor rigidity, the excited vibration is very easy to radiate relatively large noise. The higher the rotation speed of the circular saw blade, the more intense the excitation of the circular saw blade during sawing, the greater the relative vibration noise, and the more serious the noise pollution generated. Reducing the vibration of the circular saw blade itself is a main research direction of t...
