Abstract
The utility model relates to a split type motor rotor, which comprises an iron ring and a rotor end cap, wherein a magnet steel plate is installed on the inner wall of the iron ring, the rotor end cap is installed on a motor shaft through a bearing, a heat dissipation port is manufactured on the rotor end cap, and the split type motor rotor is characterized in that the iron ring and the rotor end cap are manufactured into a split type and then are connected through adopting a screw thread. The utility model adopts the technical scheme that the iron ring and the rotor end cap are manufactured in a split mode, thereby, the magnet steel plate can be firstly pasted on the inner wall of the iron ring, then, the rotor end cap can be installed on one end of the iron ring when in assembly, which is convenient for installing and disassembling the magnet steel plate.
Description
Technical field
The utility model relates to rotor, particularly relates to split type rotor, belongs to machine field.
Background technology
Electric motor car uses flexibly, and applicability is wide, can be on streets and lanes, backroad by bike; Without manpower to pedal, speed is fast, and is laborsaving, save time; Compare the saving energy with motorcycle, pollution-free; Add the profile better appearance, especially be fit to the women and use, so comparatively fast developed in recent years.Motor is the critical component of electric motor car, and the quality of motor directly influences factors such as electric motor car climbing capacity and mileages of continuation.The structure of motor mainly comprises stator module and rotor assembly, rotor assembly is made up of the iron ring of making one and rotor endcap, the iron ring inwall is pasted magnetic links, but there is following shortcoming: first, because iron ring and rotor endcap are made one, magnetic links is difficult for pasting, and also not quick detachable after pasting; The second, adopt two between motor shaft and the rotor endcap and imprison bearing for light crime, when stator cooperated with rotor, the bearing that is positioned at the rotor endcap inboard was vulnerable to impact and damages; The 3rd, the thermovent on the rotor endcap is a square opening, and radiating effect is poor.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of magnetic links of being convenient to mount and dismount to be provided, also can reduce the damage of bearings that is installed between motor shaft and the rotor endcap, and the split type rotor of good heat dissipation effect.
The technical scheme of the split type rotor of the utility model is: comprise iron ring and rotor endcap, the iron ring inwall is installed magnetic links, rotor endcap through Bearing Installation on motor shaft, be shaped on thermovent on the rotor endcap, adopt screw thread to be connected after it is characterized in that described iron ring and rotor endcap being the split manufacturing.
Split type rotor of the present utility model, compared with the prior art, because iron ring and rotor endcap split are made, therefore when assembling, can earlier magnetic links be sticked on the iron ring inwall, at an end of iron ring rotor endcap is installed again, be convenient to the installation and the dismounting of magnetic links.
Split type rotor of the present utility model, the direction of rotation of its described screw thread is identical with the direction of rotation of motor shaft, can guarantee that rotor endcap revolves tighter and tighter.Its described bearing that is positioned at the rotor endcap inboard is heavily to be bearing, because the bearing of rotor endcap inboard easily is hit, after employing heavily is bearing, can improve resistance to impact, reduces the damage of bearing.Thermovent on its electric motor end cap is trapezoidal thermovent, helps improving the heat dispersion of movement.
Description of drawings
Fig. 1 is the cross-sectional schematic of the split type rotor of the utility model;
Fig. 2 is the schematic perspective view of the split type rotor end cap of the utility model.
Embodiment
The utility model discloses a kind of split type rotor, comprise iron ring 1 and rotor endcap 2, iron ring 1 inwall is installed magnetic links 3, rotor endcap 2 is through bearing 6,7 are installed on the motor shaft, be shaped on thermovent 21 on the rotor endcap 2, it is characterized in that described iron ring 1 is connected for adopting screw thread after the split manufacturing with rotor endcap 2, as shown in Figure 1, one of iron ring 1 is shaped on internal thread 11, one of rotor endcap 2 is shaped on external screw thread 22, external screw thread 22 matches with internal thread 11, owing to, therefore when assembling, can earlier magnetic links 3 be sticked on iron ring 1 inwall with iron ring 1 and rotor endcap 2 split manufacturings, at an end of iron ring 1 rotor endcap 2 is installed again, is convenient to the installation and the dismounting of magnetic links like this.The direction of rotation of its described screw thread is identical with the direction of rotation of motor shaft, can guarantee that rotor endcap revolves tighter and tighter.Its bearing 7 that is positioned at rotor endcap 2 inboards is heavily to be bearing, because the bearing of rotor endcap inboard easily is hit, after employing heavily is bearing, can improve resistance to impact, reduce the damage of bearing, but the impulsive force that the bearing 6 that is positioned at the rotor endcap outside is subjected to is less, heavily is bearing so need not be replaced with.As shown in Figure 2, the thermovent 21 on its electric motor end cap 2 is trapezoidal thermovent, can improve the heat dispersion of movement.
