Abstract
The utility model belongs to the field of a motor technology, and relates to a dynamic balancing mechanism, especially a dynamic balancing motor rotor assembly. The utility model solves the technology problem that the prior art is designed unreasonably. The dynamic balancing motor rotor assembly comprises a rotor shaft, the rotor shaft is fixed with a magnetic steel, the two ends of the magnetic steel are respectively provided with a rotor protecting cap fixed on the rotor shaft, the rotor protecting cap is provided with several balancing holes, the balancing holes are provided with a balancing weight made of a plastic solid. The utility model has the advantages as follows: since the two ends of the rotor are provided with a rotor protecting cap respectively, the rotor protecting cap can connect with the balancing weight, realizing the axial balance of the rotor shaft and the circumferential balance of the rotor, and ensuring that the rotor in operation has good balance; the connection with the balancing block is realized through the balancing holes, convenient for the mounting and dismounting of the balancing weight, and also convenient for the quality compensation of a corresponding position by the balancing weight; and the connection is not easy to disconnect through the rotor protecting cap of the structure.
Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of dynamic balancer, particularly a kind of dynamic balancing rotor assembly.
Background technology
The rotor of DC motor normally is made up of rotating shaft and magnetic shoe bonding.Because the circumference mass distribution of magnetic shoe can not be very even, rotor can produce unbalanced centrifugal force and cause vibration in running up.So in the production technology of motor rotor, be designed with the dynamic balancing treatment process.Dynamic balancing processing means are divided into excessive quality materials and remove method and two kinds of technologies of very few quality materials additive process.For magnetic shoe, it is inapplicable to remove material.Usually adopt and add the non-uniform mass problem that material solves rotor circumference.
Because the magnetic shoe of rotor is a Ferrite Material, the surface is smooth, and is difficult to sticking as to live usually through the material that adds.Under the situation of rotor high-speed running, additive also comes off easily, can not play good counterbalance effect simultaneously.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of simple in structurely, is easy to assembling, good balance effect, the dynamic balancing rotor assembly of long service life.
The purpose of the utility model can realize through following technical proposal: this dynamic balancing rotor assembly; Comprise armature spindle; On armature spindle, be fixed with magnet steel, be respectively equipped with the rotor helmet that is fixed on the armature spindle at the two ends of magnet steel, it is characterized in that; Described rotor helmet is provided with several balancing holes, on balancing hole, is provided with the balance weight of being processed by the plastic solid thing.
In above-mentioned dynamic balancing rotor assembly, described rotor helmet is in the form of annular discs, and is provided with bound edge at the edge of rotor helmet.
In above-mentioned dynamic balancing rotor assembly, described balancing hole is arranged on the same circumference and evenly and distributes.
In above-mentioned dynamic balancing rotor assembly, described balance weight is processed by clay.
In above-mentioned dynamic balancing rotor assembly, described balance weight is arranged in balancing hole, is provided with at an end of balance weight and acts on the inboard stop part of rotor helmet, is provided with the jut that acts on the rotor helmet outside at the other end of balance weight.
Compared with prior art; The advantage of this dynamic balancing rotor assembly is: 1, owing to be provided with the rotor helmet at the two ends of rotor; And the rotor helmet can connect balance weight; Not only realize the balance of rotor axial, also realized the balance of periphery of rotor, had better balance performance when guaranteeing working rotor.2, realize being connected through balancing hole, be convenient to the installation or removal of balance weight, also make things convenient for the mass compensation of balance weight simultaneously the relevant position with balance weight.3, in addition, the rotor helmet connection through this structure is not easy to come off.
