Abstract
The utility model relates to a speed reducing type permasyn motor rotor. A circular magnet and a segmented rotating shaft are sheathed, the segmented rotating shaft comprises an upper segment rotating shaft and a lower segment rotating shaft which are sheathed. The upper segment rotating shaft is buckled in the magnet, and the other end of the lower segment rotating shaft is connected with a positioning plate of which the side is folded to extend upwards out of a fixed arm which is clamped and connected to a positioning end surface of the upper segment rotating shaft. An integral injection molding structure of a rotating shaft in an original circular magnet is changed by the utility model into a structure that the rotating shaft is in upper and lower segmented injection molding, socket joint is carried out, and finally the rotating shaft is integrally positioned by the positioning plate. The conditions of speeding abrasion of a rotating shaft cavity and a motor rotating shaft, decentration of the motor rotating shaft in turning, descent of output torque and shortened service life of a motor rotor caused by the heating and the expansion of every component, gap reduction between the rotating shaft cavity and the motor rotating shaft and friction force increase because of the long term operation of a motor between the rotating shaft cavity and the motor rotating shaft are prevented from happening. The service life of the motor rotor is greatly prolonged.
Description
Technical field
The utility model relates to a kind of slowdown type permanent-magnet synchronous motor rotor.
Background technology
At present, the small synchronous motor rotor is injection moulding rotating shaft in annular magnet, if the diameter of magnet is big more, the rotating shaft that needs to carry out injection moulding so is also big more, and the height of rotating shaft is also high more, needed injection pressure is also big more, and relative magnet thickness also increases, and can effectively prevent the magnet breakage because increase magnet thickness.But the rotor cost of manufacture of this structure is higher, and the gear beating degree in the motor is big, and because the rotating shaft of disposable injection moulding is too high, causes the axiality of rotating shaft internal cavities poor easily, causes the rotor running unstable.
The utility model content
The purpose of this utility model is to provide that a kind of simple and reasonable, low cost of manufacture, segmentation assembling, running resistance are little, the slowdown type permanent-magnet synchronous motor rotor of long service life, to overcome weak point of the prior art.
A kind of slowdown type permanent-magnet synchronous motor rotor by this purpose design, annular magnet and segmented rotating shaft socket, the segmented rotating shaft comprises epimere rotating shaft and hypomere rotating shaft, epimere rotating shaft and hypomere rotating shaft socket, its architectural feature is that the epimere rotating shaft is buckled in the magnet, the hypomere rotating shaft other end and a location-plate join, and protrude upward fixed arm after this location-plate side bending, and this fixed arm is connected on the location end face of epimere rotating shaft.
Above-mentioned location-plate fixed arm end is provided with arc fold bending, and the location hole on the end face of epimere rotating shaft location is stretched out in this arc fold bending end, is crimped in this location hole.The location-plate middle part is provided with location hole, and Dui Ying hypomere rotating shaft is provided with positioning round table therewith.Epimere rotating shaft location end face gland is on the positioning step of annular magnet, and the side of this location end face is symmetrically arranged with open slot, and this open slot is corresponding with the locating convex block on being arranged on the magnet positioning step.
Be provided with cavity in the middle of the above-mentioned epimere rotating shaft, this cavity place part is extended downwards, forms the pipe joint of an outstanding base portion; Be provided with cavity in the middle of the hypomere rotating shaft, the one end is socketed on the pipe joint of epimere rotating shaft; The cavity of epimere rotating shaft is connected with the cavity of hypomere rotating shaft, form the machine shaft chamber, the two ends up and down in this machine shaft chamber are adopted respectively with machine shaft equal diameter gap and are provided with, match with machine shaft, this middle part, machine shaft chamber diameter forms the oil storage tank of a ccontaining lubricating oil greater than the diameter of machine shaft.
Above-mentioned epimere rotating shaft top is provided with gear, is provided with the position block that is used to change the motor direction of rotation below the gear, and this position block is arranged on the end face of location.Screw thread or buckle structure socket are adopted in hypomere rotating shaft and epimere rotating shaft.
After the utility model will need the rotating shaft of integral molded plastic to resolve into epimere rotating shaft and hypomere rotating shaft originally, carry out injection moulding respectively, be provided with location-plate then below the hypomere rotating shaft, the epimere rotating shaft and the hypomere rotating shaft of socket connect as one together with annular magnet up and down by this location-plate; Guaranteeing that the motor rotor running is steadily reliable, rotating shaft has under the situation of enough intensity, reduce manufacturing cost as much as possible.
After cavity in the utility model between epimere rotating shaft and the hypomere rotating shaft is communicated with, form the machine shaft chamber, these two ends, machine shaft chamber adopt the mode that cooperates with the machine shaft equal diameter to be provided with, and guarantee the axiality in machine shaft chamber; The diameter at middle part, machine shaft chamber forms the oil storage tank of a ccontaining lubricating oil greater than the machine shaft diameter.When machine shaft rotated in the machine shaft chamber, lubricating oil can enter whole machine shaft chamber from the gap between machine shaft and the oil storage tank slowly, increased the lubricated of machine shaft, reduced running resistance, prolonged the useful life of motor rotor simultaneously.
The utility model will be rotating shaft segmentation injection moulding and then socket up and down in the structural change of annular magnet shaft integral molded plastic in the past, at last by the whole structure of locating of location-plate, and the one, reduce shot volume, reduced the injection moulding cost; The 2nd, avoided whole rotating shaft after the motor long-term operation, injection molding body heating itself is expanded, and the gap between injection moulding post-receiving chamber and the machine shaft is too small, thereby causes frictional force increase, output torque between injection moulding post-receiving chamber and the machine shaft to reduce; The 3rd, avoided the frictional force between injection moulding post-receiving chamber and the machine shaft to increase the wearing and tearing quickening that causes between injection moulding post-receiving chamber and the machine shaft, the situation generation that the injection moulding post-receiving chamber enlarges, shortened dramatically the useful life of off-centre, motor rotor when machine shaft rotated, prolonged the useful life of motor rotor greatly.
The utility model is simple and reasonable, low cost of manufacture, segmentation assembling, little, the long service life of running resistance.
