Abstract
A cup-type wound rotor with non-metal frame features that it has a cylindrical frame made of non metal, which has an open end and another end integrated with rectifier and inlaid metal part by injection mould. A rotary shaft passes through the center of rectifier and inlaid metal part and is linked by spline. The circumferential surface of cylindrical frame has slots for arranging windings in them. Its advantages are high link strength between windings and shaft, so it can be used in high-torque field.
Description
The present invention relates to technical field of motors, belong to a kind of hollow cup type winding rotor with non-metal frame.
The present hollow cup type winding rotor that uses, it is to be formed by the electromagnetic wire coiling of arranging according to certain rules in the space fully, does not have bracing frame.When lead arrange finish after, need subtly in shaping, with binding agent it is solidified again, the manufacture technology more complicated, the lead winding that makes generally also needs with binding agent it to be connected with the commutator plate, for the operation occasion of high pulling torque, the intensity of this connection is often not enough, thereby has limited the application scenario of this type of rotor.
The purpose of this invention is to provide a kind of hollow cup type winding rotor with non-metal frame, the bonding strength that it has been strengthened between electromagnetism winding and the rotating shaft greatly is applicable to high pulling torque operation occasion, and is convenient to manufacture.
For achieving the above object, the present invention takes following design: this hollow cup type winding rotor with non-metal frame, rotating shaft, rectifier, coil windings are arranged, it is characterized in that: be provided with the column type support that usefulness nonmetallic materials constitute, the one end is an open ports, the other end is by rectifier, metal inserted piece and support integrated injection molding, place the rotating shaft that useful key is connected at rectifier with the middle part of metal inserted piece, at the uniform notch that is provided with of the external peripheral surface of column type support, in notch, be provided with winding, catch is installed on winding.The end face mouth of metal inserted piece is provided with air vent hole, is beneficial to the rotor heat radiation.
The tapping point of each winding is welded on the corresponding endpoint of rectifier, with binding agent winding and support are cemented, to overcome the centrifugal force that acts on when rotor rotates on the electromagnetic wire, metal inserted piece is connected with the support integrated injection molding with the mode of inlaying, to obtain enough bonding strengths and better radiating effect.
Owing to be provided with non-metal frame and metal inserted piece, then strengthened the bonding strength between electromagnetism winding and the rotating shaft greatly, thereby be applicable to high pulling torque operation occasion, and be convenient to manufacture.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a profile schematic diagram of the present invention
Fig. 2 is the axial cross-sectional schematic of Fig. 1
Fig. 3 looks schematic diagram for Fig. 1 left side
Fig. 4 looks schematic diagram for Fig. 1 right side
Referring to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the present invention is the hollow cup type winding rotor with non-metal frame, it has rotating shaft, rectifier, coil windings, it is characterized in that: be provided with the column type support 3 that usefulness nonmetallic materials constitute, the one end is an open ports, the other end is by rectifier 4, metal inserted piece 8 and support 3 integrated injection moldings, place the rotating shaft 5 that useful key 6 is connected at rectifier 4 with the middle part of metal inserted piece 8, at the uniform notch 10 that is provided with of the external peripheral surface of column type support 3, in notch 10, be provided with winding 2, catch 1 is installed on winding 2.
In order to be beneficial to the rotor heat radiation, the end face of metal inserted piece 8 is provided with a plurality of air vent holes 7.
In order to improve support 3 and metal inserted piece 8 bonding strengths, on metal inserted piece 8 circumference, can be provided with a plurality of fins 9.
