Description

the molded buffers.

The invention relates to a vibration The motor 3 provided with the connections 1, 2.

Damped mount for motors, especially for »5, is fastened in a tube 4. The pipe 4 serves both

Fan motors, in a surrounding area, for example as an air supply pipe for a fan,

housing or duct by means of between the motor and the housing, the air being drawn onto the motor 3 through a

Housing arranged elastic, ring-shaped parts put fan blades 5 through the pipe 4 through

with webs running in the radial direction. is pressed. The air can in this case at the motor 3 in

Brush past a known vibration-damped holder 30 near the pipe 4. To the Moder at the beginning mentioned '.rt (USA.-Patent Tor 3 against the pipe 4 vibration damped to 2 9.16 141) consists of jwei hold concentrically to each other, buffers 6 are arranged between the outer jacket of the rings, which have a large number of as Spei- motor 3 and the inner jacket of the tube 4 in between the two rings S-shaped or with inserts. According to the invention, connecting webs formed in particular hold a shoulder. 35 can be seen from Fig. 3, the buffer 6 over a skin 7 The inner ring is provided with lugs, connected to each other via de-, the elastically deformable and ren inner circumferential surface he on the bearing of a v. t. Thus, in front of the engine rests; in order to secure the outer ring before the motor 3 is introduced into the pipe 4, special measures are required to be clamped onto the motor 3 and the in each case z. B. molded grooves in the outer ring, nt / wen- 40 radial position to the engine 3 attachable buffer 6 dig. held in the desired position on the motor housing

In contrast, a significantly simplified one. To prevent the motor from rotating 3

Vibration-damped bracket and assembly is opposite to the pipe 4 are groove-shaped recesses

in the case of such a holder according to the invention, on the other hand, 8 is introduced inside the tube 4. To that

due to the fact that the webs as in the axial direction 45 facilitate the introduction of the motor into the tube 4,

elongated, elastic buffers are formed, which the Rchr 4 can optionally also be divided

The housing. From the above it can be seen that

It is thus a safe, vibration-damped mount of small motors of the mount with only one ring-shaped thin part of effort by the subject matter of the invention, in particular, which is versatile, since the inven- tive special in terms of material and working time, which with large-size mounts of different diameters series What is particularly important is the fact that the motor or its bearing point could be reduced to a certain extent. The skin and the buffer zen adapted and in any length according to 55 can be made of plastic as well as rubber to the respective axial dimensions of the Mo to be held, which on the one hand can be cut off after the gate. On the side of the buffer opposite the thin damping frequency and on the other hand towards the skin, this elasticity of the skin is aimed at holding the buffer, directly on the housing or on the channel in which the motor is to be kept when the manufacturing process is carried out with the skin , at. This has technical advantages over buffers compared to 60 bound buffers, which are composed of various types of support, mainly ventilation materials. When holding fans in a uniform material is hardly more complex, the cross section which is free of buffers, for example, also in the extrusion process, is not reduced by a second external with visual vibration damping properties for a channel serving for air transport. When assembling the engine, e.g. B. can be produced in 65 different frequencies. The buffer, a tubular housing, on the inner wall of which the attenuators are to be supported in the exemplary embodiment are cuboid, exists, but any other shape, despite the simplest design, is not conceivable.
