Embodiment Construction

[0008] exist figure 1 with 2 A side view of the device according to the invention is shown in , in which the housing 5 of the electric motor 1 is shown in section. The second housing half generally has the same shape, but is turned into a mirror image opposite position. Advantageously, the two halves are detachably connected to form a whole.

[0009] The device consists of three elastic blocks 2 , 3 , 4 , wherein the stator is fixed by means of elastic blocks 3 and 4 and the rotor is fixed by means of elastic block 2 . Also shown by way of example in these two figures is a transmission gear pair consisting of a worm wheel 50 mounted on the shaft of the motor 11 and gears 51 , 52 and 53 .

[0010] exist image 3 with 4 shown in figure 1 with 2 View of , however without motor 1. Contact points 30 , 31 , 31 ′ and 32 , which are formed in the housing ribs, can be seen in these two figures. The contact points 30 ′, 31 ″, 31 ″′ and 32 ′ are formed parallel within the second...

Abstract

The invention relates to a device for damping the vibrations and noise of an electric motor (1) embedded in a housing (5) by three elastic blocks (2, 3, 4), wherein the stator is formed by the elastic blocks (3) and (4) and the rotor is fastened by means of the elastic block (2).

Description

technical field [0001] The present invention relates to a device for vibration damping and noise reduction of electric motors in various technical fields. Background technique [0002] Motors generate vibration and noise during operation. Its vibration damping and sound attenuation are mainly achieved by damping and sound attenuation of the entire housing by means of different linings, seals, cotton linings, etc. when the motor is installed in the housing. Disadvantages of the current state of the art are the low vibration and sound damping effect, the high installation space requirements and the resulting high costs. Contents of the invention [0003] Eliminate above-mentioned deficiency by technical scheme of the present invention. This is an elastic electric motor insertion. The electric motor is embedded in the housing by means of several elastic blocks which cushion not only the stator but also the rotor of the electric motor. It is advantageous to dampen vibratio...
