Description
Technical field
The utility model relates to field of motor manufacturing, is specially a kind of rotor pressing plate.
Background technology
At present, when design of electrical motor, rise for preventing electric machine rotor iron core generation tooth or punching loosen problem, the sheet metal of a band ventilation hole and pressing plate tooth is respectively provided with as rotor press plate at rotor core two ends, when rotor laminates, after itself and iron core are aligned, compress and fix.In addition, because rotor is high-speed rotary part, need rotor dynamic balancing be carried out, usually also on two ends of rotor axle, respectively a balancing frame will be installed, carry out dynamic balancing, to prevent motor oscillating, reduce damage of the bearing.Usually, the rotating shaft inside motor bearings at both ends also needs arrange the oil sealing preventing bearing grease from revealing, it arranges several layers of labyrinth, to play the effect stoping lubricating grease to be revealed.But usually adopt sheet metal as rotor press plate at present, its intensity is lower slightly, when its teeth portion generation permanent deformation, the problem that rotor core local tooth rises can be caused; Rotating shaft is arranged balancing frame and oil sealing, relates to parts more, complex operation, and there is the tolerance stack problem of installing.
Summary of the invention
The utility model is solve current rotor press plate using complex operation in assembling process and there is the accumulative technical problem of the tolerance of installing, and provides a kind of electronics rotor press plate.
The utility model 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, pressing plate is positioned at the outer compensating groove being arranged with ring-type of ventilation hole.
The utility model, in the structural design of rotor pressing plate, is integrated with the effect strengthened pressure plate structure, arrange compensating groove and oil sealing labyrinth.
Arrange installation axle hole and positioning spline by center, rotor press plate accurately can be located and be firmly arranged in the rotating shaft of motor, ventilation hole and pressing plate tooth and rotor-core lamination are aligned after being located by positioning spline completely.After pressurization is installed, pressing plate tooth being pressed in rotor core tooth from rotor core both sides tightly, the problem such as prevent iron-core lamination generation tooth from rising and to loosen.In addition, rotor press plate being provided with is convenient to the compensating groove carrying out rotor dynamic balancing, carries out rotor dynamic balancing by installing the special balance weight corresponding with it, and the layout of compensating groove considers the design factor that equilibrium radius is comparatively large, balance weight is convenient to installation.And the oil sealing labyrinth that rotor press plate is arranged coordinates with the end cap that motor is installed or bearing cap, can effectively prevent grease from revealing, 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 that the thickness to electrolysis at the bottom of pressing plate compensating groove meets requirement of strength, the requirement of satisfying dynamic equilibrium technological operation feasibility, this is that those skilled in the art easily realize.
The beneficial effect that the utility model brings: by increasing thickness of compressive plate, and compensating groove and oil sealing labyrinth are set, make rotor press plate meet the effect compressing iron-core lamination, carry out dynamic balancing and prevent grease from revealing simultaneously, simplify rotor compression, dynamic balancing, the structure of oil sealing and manufacturing process, solving it in use assembles loaded down with trivial details, the problem that consistency is poor, realizes not only can improving intensity but also efficiently can 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, pressing plate is positioned at the outer compensating groove 6 being arranged with ring-type of ventilation hole 3.
Pressing plate tooth 4 size that described rotor press plate is arranged is less than supporting core tooth, interferes when rotor cage can be avoided to assemble.
Ventilation hole 3 size that described rotor press plate is arranged is greater than supporting core ventilation hole.
The oil sealing labyrinth 5 that described rotor press plate is arranged coordinates with the end cap that motor is installed or bearing cap, can effectively prevent grease from revealing, play 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).
