Abstract
The utility model discloses an electric saw with a muffler, comprising an electric motor, a belt pulley, a belt, a power shaft, an operating desk, and saw blades. The electric motor is connected with the belt pulley and the belt to form a power system to provide power for the electric saw through the power shaft; the power shaft is fixed on the operation desk; the saw blade is fixed on the power shaft, and both sides of the saw blade are provided with pads and limiting screw nuts; both sides of the saw blade are respectively provided with a rubber pad playing the function of muffling, and the rubber pads are tightlyclung to the saw blade. As the two rubber pads are tightly arranged on the saw blade clung on the power shaft of the utility model, the vibration of the saw blade can be decreased, and the noise can be reduced; in addition, the vibration during the running of the saw blade can be reduced through a friction plate arranged near the saw tooth, and the noise is greatly reduced.
Description
Technical field
The utility model relates to a kind of electric saw, refers to a kind of electric saw with silencing means especially.
Background technology
Electric saw is the indispensable instrument of wood working industry, yet under no-load condition, saw blade is with producing very big noise owing to vibrating in the process of air contact, the huge noise that electric saw produced under working condition pollutes environment especially, has a strong impact on user and near resident's health.At present, occur though have some electric saws with silencing function,, these electric saws are complex structure not only, and erasure effect is unsatisfactory.For a long time, this problem fails to be solved all the time.
The utility model content
At the problems referred to above, the purpose of this utility model is according to metal noise reduction, acoustic principle, and a kind of electric saw that has silencing means of simple in structure, good muffling effect is provided.
For achieving the above object, solution of the present utility model is:
A kind of electric saw with silencing means, comprise motor, belt pulley, belt, line shaft, operating desk, saw blade, motor and belt pulley, belt are connected to form dynamical system and provide power by line shaft for electric saw, line shaft is fixed on the operating desk, saw blade is fixed on the line shaft, the saw blade both sides are provided with pad and stop nut, are close to the rubber blanket that saw blade has been respectively equipped with sound deadening in described saw blade both sides.
Further, on described operating desk, be provided with friction plate with the saw blade opposite position.
Further, described friction plate comprises a sheet rubber and a sheet metal, and this sheet metal with the sheet rubber clamping wherein.
Further, described sheet metal has certain camber, and described sheet rubber is close to the sawtooth of saw blade and close described saw blade.
After adopting such scheme, because the utility model is close to saw blade and is provided with two sheet rubbers on line shaft, can reduce the vibration of saw blade, reduce noise, in addition, the vibration when the friction plate of establishing near the sawtooth place reduces saw blade work significantly reduces noise.
Description of drawings
Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is a side-looking structure chart of the present utility model.
The specific embodiment:
Specify the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises motor 1, belt pulley 2, belt 3, line shaft 4, operating desk 5, saw blade 6, rubber blanket 7, pad 8 and nut 9, motor 1 and belt pulley 2, belt 3 is connected to form dynamical system and provides power by line shaft 4 for electric saw, line shaft 4 is fixed on the operating desk by two bearings, also be provided with keyway and screw thread on it, saw blade 6 is connected and fixed on the line shaft 4 by key, be close to the rubber blanket 7 that saw blade has been respectively equipped with sound deadening in the saw blade both sides, rubber blanket 7 outsides are provided with pad 8 and nut 9 successively, nut 9 is fixed together saw blade 6 and line shaft 4, under the dynamical system effect, saw blade 6 can be rotated with line shaft 4.Because of rubber blanket 7 is an elastomeric material, can reduce the vibration of saw blade, thereby reduce noise.
In addition, as shown in Figure 2, bottom surface with the saw blade opposite position on operating desk has been screwed friction plate 10, this friction plate comprises a sheet rubber 101 1 sheet metals 102, this sheet metal 102 with sheet rubber 101 clampings wherein, this sheet rubber can be fixed on the sheet metal with screw, or makes that sheet rubber is enough thick directly to be held between the sheet metal.This sheet metal has certain camber, make sheet rubber 101 be close to saw blade 6, and make the sawtooth of sheet rubber 101 near saw blade 6, because of electric saw vibration maximum near sawtooth place saw blade when working, make sheet rubber can farthest reduce vibration, reduce noise near the sawtooth of saw blade.Said apparatus is particularly useful for the metal saw blade.
Claims (4)
1, a kind of electric saw with silencing means, comprise motor, belt pulley, belt, line shaft, operating desk, saw blade, motor and belt pulley, belt are connected to form dynamical system and provide power by line shaft for electric saw, line shaft is fixed on the operating desk, saw blade is fixed on the line shaft, the saw blade both sides are provided with pad and stop nut, it is characterized in that: be close to the rubber blanket that saw blade has been respectively equipped with sound deadening in described saw blade both sides.
