Definitions
- the invention relates to the device for vibration and noise damping of an electric motor in any field of technology.
- FIG. 1 the device according to the invention is shown in a side view, wherein the housing of the electric motor is shown in section.
- FIGS. 3 and 4 show the analogous views of FIGS. 1 and 2, but without an electric motor.
- Fig. 5 shows the electric motor and half of the housing in section.
- Fig. 6 shows the detail of the elastic block of the rotor.
- Fig. 7 is the axonometric view of the face of the electric motor with tripod without elastic block, in Fig. 8 then shown with the elastic block.
- Fig. 1 and 2 the device according to the invention is shown in a side view, wherein the housing 5 of the electric motor 1 is shown in section.
- the second half of the housing usually has the same shape, but is rotated mirror-inverted. Both halves are advantageously separable connected to a whole.
- the device is formed by three elastic blocks 2, 3, 4, wherein the stator is fixed by means of the elastic blocks 3 and 4 and the rotor by means of the elastic block 2.
- the gear pair formed by the worm wheel 50 mounted on the motor shaft H and the gears 5_1, 52 and 53 are shown.
- FIGS. 1 and 2 the analog views of FIGS. 1 and 2 are shown, but without electric motor ⁇ .
- the contact points 30, 31, 3_11 and 32 can be seen, which are formed in the Gezzausedrippung 5. In parallel, these are formed in the second housing half 301, 3T, 3JT and 321. It is usually a recess in round or elliptical shape, which copies the outer contour of the electric motor 1, and the elastic blocks 2, 3, 4.
- the elastic plastic block 4 ensures the protection against displacement of the electric motor 1 in the axial and radial directions. This has the shape of a flange and is mounted on the rear side 15 of the stator of the electric motor.
- the elastic block 4 is parallel elastically embedded in the housing 5 at the location of the contact points 30, 301 embedded in the Gescousiverrippung.
- the elastic block 4 is provided with a base 24 which controls the displacement of the Electric motor 1 prevented in the axial and radial directions.
- the pad 24 is located within the elastic block 4 and abuts the motor at the level of the rotor axis.
- the material of the pad 24 may be made of any material, such as plastic or metal.
- the elastic plastic block 3 ensures the protection against displacement of the electric motor 1 in the axial and radial directions. This has the shape of a flange and is mounted on the front side 10 of the stator of the electric motor 1.
- the elastic block 3 is parallel elastically embedded in the housing at the location of the contact points 31. 3jT, 3jT, 31 '"formed in the Gescousiverrippung.
- Fig. 5 the electric motor 1 and the housing 5 is shown in section.
- Fig. 6 shows the detail of the elastic block 2 of the rotor in section.
- the elastic plastic block 2 is inserted through a fixed member 20 in the form of a cap with a recess 26 and a flange 27, a rubber ring 21 in the recess 26 and a fixed cover 22 in roll form with internal miter, which is sprung over the rubber ring, formed.
- the end of the rotor shaft H is exposed in the fixed member 20.
- the rotor shaft H rotates in the fixed member 20.
- the fixed cover 22 is located in the recess 32, 32 ⁇ in the Gepuriverrippung the electric motor. 1
- Fig. 7 and 8 the axonometric view of the Stinrseite the electric motor 1 with tripod 12 without elastic block 3, in Fig. 8 then shown with the elastic block 3.
- the elastic block 3 is the opening 25 in the form of a three-pointed star, in which the tripod 12, secured to the end face 10 of the electric motor 1, engages.
- the device for damping the vibration and noise of the electric motor can be used in any area of the art where the electric motor has an application.
