Definitions
- the invention relates to a device for vibration-decoupling mounting of an electrical machine according to the preamble of claim 1.
- Electric machines are used in all areas of daily life; in particular as electric motors, they are used practically everywhere. When starting an electrical machine and during its operation, there are vibrations that make it necessary to decouple the electrical machine to its holder or to the surrounding environment.
- vibration decoupling are known to a
- Running noise of the electric motor and run-induced, for example, generated by an imbalance of a driven impeller vibrations are transmitted here to a large extent on the housing or the housing cover of the electric motor and lead to an undesirable noise, unless they were damped.
- Common attachment methods for such motors are to encapsulate the entire motor, so to use as in a plastic housing or a metal housing to which a flange is provided for connection to its environment. Between motor and motor housing or in the flange here decoupling elements are inserted approximately made of rubber to dampen vibration excitations.
- the object of the invention is to provide a device for vibration-decoupled mounting of an electrical machine which avoids these disadvantages and provides good vibration damping a secure attachment with the utmost avoidance of setting behavior of the electric machine relative to the motor flange and / or housing.
- a device for vibration-decoupled posture of an electrical machine which has a pole housing and a machine flange, between which at least one vibration decoupling element is arranged, which rests against at least one contact surface of PolgePFuse and / or motor flange and at least partially has a spherical shape. It is envisaged that the contact surface is shaped adapted to the ball-like shape.
- the sufficiently secure fixation of the individual parts to be decoupled ie in particular the pole housing and the Motor flange or the motor housing
- the vibration decoupling elements which had to be so strong that the vibration decoupling elements by frictional force the weight and / or kinetic energy in particular of the starting engine and the resulting torque could absorb without it undesirable large relative movement of these parts came to each other.
- the contact surfaces on which the vibration decoupling element bears against the pole housing and / or motor flange are formed, at least in regions, in such a way that they are formed in a shape adapted to the sphere-like shape of the vibration decoupling element. It is therefore not only a frictional connection, but at least partially between the vibration decoupling element and the pole housing and / or motor flange
- Vibration decoupling element can be constructively taken and maintained, but in particular that the vibration decoupling element must not be introduced under unnecessary bias, which also improves the vibration decoupling properties of the vibration decoupling element.
- Vibration decoupling element consists of elastic material.
- the vibration decoupling element of elastic material for example made of rubber or an elastic plastic
- the vibration-decoupling properties can be widely varied and adapted to the particular requirements of the electrical machine to be decoupled be, especially on their expected, to be vaporized frequency spectrum.
- By suitable selection and arrangement of elastic vibration decoupling elements unwanted resonances in several areas can be avoided as far as possible.
- Vibration decoupling element on two ball-like formations which are connected to each other via a web.
- the vibration decoupling element is thus formed in the manner of a dumbbell, wherein on both end sides of a web, the ball-like formation is arranged.
- the web allows to bring the vibration decoupling element in a very simple manner, for example, in mounting straps and thereby connect to the pole housing, the machine flange or a housing component of the electrical machine, for example, clipped, which allows a very simple and inexpensive installation, which also can be designed self-holding by the web is dimensioned short relative to the strength of the fastening tab, so that the ball-like formations clamp on both sides.
- both ball-like formations bear on shape-adapted contact surfaces of the pole housing and / or machine flange.
- the one ball-like design rests against mating contact surfaces of the pole housing and the other abuts against a machine flange, or that both ball-like formations abut respectively on conformal contact surfaces of pole housing and / or machine flange. It is thus possible to make the one ball-like formation rest only on a shape-matched contact surface of the pole housing and the other only on a shape-matched contact surface of the machine flange, or a ball-like
- the electric machine has a housing cover which adjoins the housing Vibration decoupling element supported with a contact surface.
- the housing cover has a contact surface which comes into contact with the vibration element and is supported thereon.
- Vibration decoupling element is formed adapted.
- the contact surface which serves to support the housing cover on the vibration decoupling element, is thus adapted to the ball-like shape of the vibration decoupling element as well as the contact surfaces with which the motor flange or the pole housing are supported.
- a relative displacement of said individual components, so in particular of the pole housing, the motor flange and the housing cover to each other, which could be done by shifting or sliding of these components on the vibration decoupling element is reliably virtually completely avoided, since the components not only via frictional connection, but via positive locking abut the vibration decoupling element.
- Figure 1 shows an electrical machine in installation position
- FIG. 2 shows a vibration decoupling element with shape-adapted
- FIG. 3 shows a housing cover with contact surfaces.
- FIG. 1 shows an electric machine 1, namely an electric motor 2 with a pole housing 3.
- the electric motor 2 is surrounded and held by a motor flange 4, and by a housing cover 5, which is slipped over the electric motor 2 and applied to the motor flange 4, embrace.
- fastening tabs 6 are formed radially, of which only one is shown here.
- the fastening tabs 6 are in particular formed integrally with the pole housing 3, for example by means of a stamping / embossing process.
- These fastening tabs have a recess into which a vibration decoupling element 7 is introduced, which is formed in the form of a dumbbell 8, which consists of two ball-like formations 9, which are connected to each other by means of a web 10.
- the web 10 is introduced into said recess of the fastening tab 6, so that the ball-like formations 9 come to lie on one side as well as on the other side of the fastening tab 6.
- the ball-like formations 9 the one is supported on a contact surface 11 of the pole housing 3 and on a contact surface 12 of the housing cover 5, while the other is supported on a contact surface 11 of the motor flange 4.
- vibration isolation elements 7 relative to the individual components of the electric motor 2, in particular to Polgefelduse 3, the motor flange 4 and the housing cover 5. De training of Contact surfaces 11 and the contact surfaces 12 is not relevant here. Contrary to the illustration, the electric motor 2 is held and damped by a plurality of vibration decoupling elements 7. These can be distributed for example in a symmetrical or asymmetrical arrangement around an outer circumference 13 of the pole housing 3.
- FIG. 2 shows a detail of a device according to the invention for vibration-decoupled holder.
- the vibration decoupling element 7 is again designed as a dumbbell 8, wherein the web 10 is introduced into a fastening tab 6 formed on the pole housing 3 of the electric motor 2, so that the ball-like formations 9 of the vibration decoupling element 7 lie on both sides of the fastening strap 6 (in the axial extent of the motor).
- the electric motor 2 is surrounded by the motor flange 4, which has an annular peripheral edge configuration 14, in which the housing cover 5 is introduced with a Stülprand 15 and thus slipped over the electric motor 2.
- the motor flange 14 has a bearing surface 17 which is adapted to the ball-shaped embodiment 9 and forms the mating contact surface 11 on the motor flange and is adapted to the outer contour of the ball-like embodiment 9.
- the housing cover 5 On the substantially opposite side (viewed in axial extension of the dumbbell 8), the housing cover 5, the contact surface 12, which is also adapted to the outer contour of the ball-like formation 9 and in this case the housing cover bearing surface 18 is formed.
- the shape adaptation takes place substantially in such a way that the contact surface 11 or the contact surface 12 has a rounded recess with a radius which approximately corresponds to that of the ball-like embodiment 9.
- Figure 3 shows a housing cover 5 for the electric motor 2, not shown, with contact surfaces 12 according to the invention, which are respectively arranged on the end cap supports 20.
- the lid supports 20 engage around the electric motor 2, not shown, in particular, the pole housing 3, not shown, and lie with the contact surfaces 12 to form end-side support portions 21 on the ball-like formations 9, not shown.
- a total of three not shown vibration decoupling elements 7 are formed, each supported with a ball-like formation 9 on the contact surface 12.
- the contact surface 12 is for this purpose not configured flat, but takes on the outer contour of the ball-like formations 9 described in the preceding figures, so that a substantial enclosure is given in particular to the ball circumference of the ball-like formations 9 out.
- the housing cover 5 relative to the ball-like formations 9 experiences an axial or radial movement in not provided by the vibration decoupling element 7 (see the preceding figures) extent; it is also prevented that the electric motor 2, which is attached to the housing cover 5 via the above-described vibration decoupling elements 7, relative to the housing cover 5 can experience an undesirably large movement, for example by settling behavior due to its own weight in a corresponding mounting position, the mere friction between ball-like Training 9, as described above, and the contact surface 12 alone can not be prevented could.
- the positive connection with the ball-like formation 9 caused by the shape-adapted configuration of the contact surface 12 permits a secure and unambiguous and sustainable positioning of the housing cover 5 via the cover supports 20 relative to the ball-like formations 9 (not shown).
