Definitions
- the present invention discloses a mounting system for electric motors comprising a clamping bracket provided with an annular shaped body and structures arranged at its perimeter for motor clamping in place of traditional flange rings.
- an electric motor refers to a machine designed to transform electrical energy into mechanical energy, the most common types being induction motors.
- the manufacture of the "bearing" or “cap” component requires high dimensional accuracy due to the concentricity of motor bearings and stator mounting fittings, representing a crucial point in the magnetic air gap of an electric motor, as
- the bearing also mounted radially inside supports the rotor of a motor, be it magnet or squirrel cage, for example.
- JP6022491 discloses a motor comprising a combination of brackets retachable at the edges as a means of attachment, thereby eliminating the use of rods or screws for fixing the bearing caps.
- JP2002101598 discloses a support comprising a bowl-shaped body and a flange projected radially from the edge of said body in order to increase the rigidity of the flange and where the fastening of the bearing caps are fixed to each other simultaneously.
- US2009160276 discloses a motor comprising a rotor core and a stator core.
- the stator core includes three mounting bracket parts and at least one stator core end bracket interconnected by their respective stator core supporting portions and is primarily intended for alignment between them.
- US5696416 discloses a motor mounting device comprising a lid in communication with a mounting bracket having an integral center span wherein the outer surface of the lid has two arms projecting in opposite directions and shaped outwardly shaped fins. complementary to the plates or bosses in the carcass.
- US5332188 discloses an electric motor mounting bracket for reducing or isolating motor vibration and blade imbalance consisting of a housing and a support comprising at least two arms independent of each other, each arm having a plate for adapting the arms in the housing, an extender with an end connected to said plate perpendicular to it, and a flange.
- JP11041856 discloses a motor mount that can be attached, regardless of mounting bracket form, to any DC motor, comprising a bearing face, using a vibration proof rubber and flange mounting slots.
- US2002190186 discloses a motor assembly constructed from a single sheet metal comprising a strip and radial projections that will hold the motor in its housing. The main purpose is to eliminate coupling screws.
- US5767596 discloses dynamoelectric machines comprising cup-shaped structures forming a housing that protects the stator and a second housing, positioned on the exposed face of the stator and connected to the first housing by means of ears, including the use of special screws, in which the The form of attachment to the equipment is made by one of the caps containing the flange.
- CN101145707 discloses a motor mounting structure comprising a housing provided with a stator, a rotor and two or more symmetrically distributed mounting wafers on the outer wall of the housing.
- the document GB2414867 reveals a motor in its external contour, whose housing is equipped with cookies that will attach the lid.
- the constructive characteristics of this motor allow mounting in different orientations.
- the main use refers to a type of extruded symmetrical casing.
- WO2007113071 discloses an electric motor comprising an outer frame, a stator accommodated in said frame, one or more support means attached to the outer side.
- US2006261692 describes a motor cover comprising a housing from a metal housing and a plastic brushed flange, where the purpose of the invention is to optimize the mounting interchangeability of the mounting brackets to the equipment with respect to the cup housing with fittings that facilitate and guarantee its positioning.
- US2011115325 discloses a type of motor bearing comprising mounting flange with a plurality of recesses configured to receive fasteners to standardize variation in mass manufacturing process.
- the present invention aims to standardize the basic mechanical engine platform by revealing a mounting system with engine mounting bracket to ring-shaped equipment to reduce the variability of high-liability parts such as covers, housings, bearings, and shafts. , allowing the standardization of manufacturing of these more complex components, concentrating all the line diversification into one component - the wrap support described.
- the present invention allows interlocking the motor bearings so that the bracket is axially secured between the motor bearings without the use of additional fasteners, maintaining the concentricity between stator and rotor and the simultaneous trapping between the bearings and the fixing flange to the equipment.
- Another advantage relates to the manufacture of this component, as its production requirements are lower than its field of dimensional tolerances.
- Figure 1 illustrates a perspective view of the bracket.
- Figure 2 illustrates a perspective view of a support embodiment.
- Figure 3 illustrates a side view of a support embodiment.
- Figure 4 illustrates a bottom view of a support embodiment.
- Figure 5 illustrates a top view of a support incorporation.
- Figure 6 illustrates a perspective view of an embodiment of the bracket coupled to an electric motor.
- Figure 7 shows a cross-sectional view in the region of the fixing ears of the bracket coupled to an electric motor.
- Figure 8 illustrates a perspective view of another embodiment of the holder.
- Figure 9 illustrates a cross-sectional view in the region of the radial and axial engagement outside the ears and motor attachment means.
- the latter support comprises an annular shaped body (1) having at least two radially arranged ears equidistant from each other on the outer surface of ( 1) .
- Said ears (3) have central holes (3a) and are housed in cutouts (5), in agreement with the complementary structures (6) of the bearing (4a) and (4b) of the electric motor (4), as can be observed in the Figures 7 and 9.
- annular body (1c) comprising a wall (1a) and a recessed wall (1b); from the outside of the wall (1a) radially disposed securing means (2) protrude.
- the motor bearing (4a) and (4b) will be installed in the bracket to be mounted by lugs (3) through fastening means such as rivets or bolts through holes (3a) located in the central region of (3). .
- the securing means (2) are dimensioned adequately to the needs of each equipment (in this case the motor being fixed to the equipment through rods, screws, or other fastener).
- Each ear (3) must be designed so that the complementary frames (6) of the electric motor bearing (4a) fit into the indentations (5) located below (3).
- the ears (3) are fitted against the frames (6), so that the shoulder (4c) of the electric motor bearing (4b) is axially locked between them. Also the radial alignment is made through the surface (3b) of the support (1) in contact with the surfaces (4d) of the bearing (4a) and surface (4e) of the bearing (4b), as can be seen in figures 7 and 9. .
- the body perimeter (1c) has three equidistant fixing means (2), projected externally from (1a), and located between the ears (3), in radial direction.
- the ears (3) protrude from the wall (lb) to the wall (la).
- the cutouts (5) will allow the attachment of complementary structures (6) present in the motor (4a), fixing it in the support (1c).
- the support (1d) comprises semicircularly shaped ears (3) arranged equidistant from one another.
