Abstract
The invention relates to the manufacturing field of a motor and specifically discloses a motor rotor pressing plate. Through the motor rotor pressing plate, the technical problem of complex operation and installation tolerance accumulation during assembling is solved in the present rotor pressing plate. The motor rotor pressing plate is characterized in that a pressing plate center is provided with an installing axle hole, and pressing plate gears are uniformly arranged around the outer edge of the pressing plate; the upper part of the installing axle hole is provided with a positioning key slot fixedly connected with a core stamping sheet, and ventilation holes are uniformly arranged around the outside of the installing axle hole; the pressing plate positioned between the ventilation hole and the installing axle hole is provided with an oil seal maze, and the pressing plate at the periphery of the ventilation hole is provided with an annular balancing slot. To the motor rotor pressing plate, by increasing the thickness of the pressing plate and arranging the balancing slot and the oil seal maze, the rotor pressing plate can simultaneously compress the core stamping sheet, execute dynamic balance and prevent oil from leakage, thereby simplifying the compressing, dynamic balance and oil seal structure of the motor and the manufacturing process and solving the problem of complex assembling and weak uniformity in use.
Description
Technical field
The present invention relates to field of motor manufacturing, be specially a kind of rotor pressing plate.
Background technology
At present, in the time of design of electrical motor, be the problem that prevents that electric machine rotor iron core generation tooth from rising or punching is loosening, respectively be provided with a sheet metal with ventilation hole and pressing plate tooth at rotor core two ends as rotor press plate, in the time that rotor laminates, after itself and iron core are aligned, compress and fix.In addition, because rotor is high-speed rotary part, need carry out rotor dynamic balancing, conventionally also will a balancing frame be respectively installed on two ends of rotor axle, carry out dynamic balancing, to prevent motor oscillating, reduce damage of the bearing.Conventionally, in the rotating shaft of motor bearings at both ends inner side, also need the oil sealing that prevents that bearing grease from revealing is set, on it, arranged several layers of labyrinth, to play the effect that stops lubricating grease to be revealed.But conventionally adopt at present sheet metal as rotor press plate, its intensity is lower slightly, in the time there is permanent deformation in its tooth portion, the problem that can cause the local tooth of rotor core to rise; In rotating shaft, arrange balancing frame and oil sealing, relate to parts more, complex operation, and there is the tolerance stack problem of installing.
Summary of the invention
The present invention solves current rotor press plate using complex operation in assembling process and having the technical problem of the tolerance accumulative total of installing, and a kind of electronics rotor press plate is provided.
The present invention realizes by the following technical solutions: a kind of rotor pressing plate, and pressing plate center is provided with installation axle hole, and pressing plate outer rim border is evenly equipped with pressing plate tooth; Installation axle hole top has the positioning spline for being fixedly connected with iron-core lamination, and the border, outside of installation axle hole is evenly equipped with ventilation hole; Border, region on pressing plate between ventilation hole and installation axle hole is provided with oil sealing labyrinth, is positioned at the outer compensating groove that is arranged with ring-type of ventilation hole on pressing plate.
The present invention in the structural design of rotor pressing plate, the integrated effect of strengthening pressure plate structure, compensating groove and oil sealing labyrinth being set.
By center, installation axle hole and positioning spline are set, rotor press plate accurately also firmly can be arranged in the rotating shaft of motor location, ventilation hole and pressing plate tooth and rotor-core lamination align after locating by positioning spline completely.After pressurization is installed, pressing plate tooth being pressed in rotor core tooth from rotor core both sides tightly, prevents that iron-core lamination generation tooth from rising and the problem such as becoming flexible.In addition, rotor press plate being provided with is convenient to carry out the compensating groove that rotor dynamic balancing is used, and carries out rotor dynamic balancing by the special balance weight corresponding with it is installed, and the layout of compensating groove has considered that equilibrium radius is large, balance weight is convenient to the design factor of installing.And the oil sealing labyrinth of rotor press plate setting coordinates with the end cap of installing on motor or bearing cap, can effectively prevent grease leakage, play the effect of seal grease.
The setting of described compensating groove, for realizing the dynamic balancing of rotor.Those skilled in the art just can produce associated balance weight according to the structure of compensating groove.The shape of compensating groove and opening direction, need to consider to meet requirement of strength to the thickness of electrolysis at the bottom of pressing plate compensating groove, the requirement of capable of satisfying dynamic equilibrium technological operation feasibility, and this is that those skilled in the art easily realize.
The beneficial effect that the present invention brings: by increasing thickness of compressive plate, and compensating groove and oil sealing labyrinth be set, rotor press plate is met simultaneously to be compressed iron-core lamination, carry out dynamic balancing and prevents the effect that grease is revealed, structure and the manufacturing process of rotor compression, dynamic balancing, oil sealing are simplified, solving it in use assembles loaded down with trivial details, the problem that consistency is poor, realizes and not only can improve intensity but also can efficiently assemble and improve conforming object.

Embodiment
A kind of rotor pressing plate, pressing plate center is provided with installation axle hole 1, and pressing plate outer rim border is evenly equipped with pressing plate tooth 4; Installation axle hole 1 top has the positioning spline 2 for being fixedly connected with iron-core lamination, and the border, outside of installation axle hole 1 is evenly equipped with ventilation hole 3; Border, region on pressing plate between ventilation hole 3 and installation axle hole 1 is provided with oil sealing labyrinth 5, is positioned at the outer compensating groove 6 that is arranged with ring-type of ventilation hole 3 on pressing plate.
Pressing plate tooth 4 sizes of described rotor press plate setting are less than supporting core tooth, can avoid the assembling of rotor mouse cage time, interfere.
Ventilation hole 3 sizes of described rotor press plate setting are greater than supporting core ventilation hole.
The oil sealing labyrinth 5 of described rotor press plate setting coordinates with the end cap of installing on motor or bearing cap, can effectively prevent grease leakage, plays the effect of seal ring.
By increasing thickness of compressive plate, by rotor balancing groove together with oil sealing labyrinth or be optionally integrated on rotor press plate; Independent thickness of compressive plate is 6～15mm, and the rotor press plate thickness in integrated compensating groove 6 and oil sealing labyrinth 5 is that 20～35mm(is greater than prior art rotor press plate thickness).
