Abstract
The utility model relates to a plastic-package motor which comprises a stator assembly, a rotor assembly, a front bearing housing, a rear bearing housing, a plastic-package shell, a front bearing, a rear bearing and a motor shaft, wherein the rotor assembly is fixedly installed on the motor shaft, the front bearing housing and the rear bearing housing are respectively arranged at the front end and the rear end of the rotor assembly, the stator assembly is arranged on the external side of the rotor assembly and the plastic-package shell is arranged on the external side of the stator assembly. The plastic-package motor is characterized in that the front bearing housing and the rear bearing housing are in two coaxial opposite-opening structures with concave and convex grooves which are arranged alternately, the central concave positions of the front bearing housing and the rear bearing housing are positions at which the front bearing and the rear bearing are respectively installed, and the central concave positions respectively face to the front end and the rear end of the rotor assembly. Since the front bearing housing and the rear bearing housing are in the coaxial opposite-opening structures with the concave and convex grooves which are arranged alternately, the central concave positions are the positions at which the front bearing and the rear bearing are respectively installed and the central concave positions respectively face to the two ends of the rotor assembly, the plastic-package motor has the advantages that the distance between the installation positions of the two bearings is reduced, the span between the front bearing and the rear bearing is reduced, the internal structure of the plastic-package motor is more compact, the volume is smaller, and the vibration and the noise of the motor are effectively reduced.
Description
Technical field
The utility model relates to a kind of plastic packaging motor, belongs to the improvement technology of plastic packaging motor structure.
Background technology
The internal structure of tradition plastic packaging motor is relatively loose, as shown in Figure 1, the all complete evagination of its both sides bearing chamber 11 is in plastic packaging shell 12, bearing 13 devices are in the mount pad inboard of bearing chamber 11 evaginations, cushion rubber 14 devices are on the cylindrical of bearing chamber 11 and in order to plastic packaging motor is fixed on other application apparatus that need mate, this internal structure external structure makes the span of the front and back bearings 13 of traditional plastic packaging motor grow than plastic packaging shell 12, not only volume is bigger, and be unfavorable for controlling the vibration and the noise of motor, when running into the compact application apparatus of some internal structures, traditional plastic packaging motor can not be satisfied the demand fully.
Summary of the invention
The purpose of this utility model be consider the problems referred to above and provide a kind of reasonable in design, volume is small and exquisite, internal structure is compact, can effectively reduce the plastic packaging motor of motor oscillating and noise.
The technical solution of the utility model is: a kind of plastic packaging motor, comprise stator module, rotor assembly, the fore bearing chamber, the rear bearing chamber, the plastic packaging shell, front and back bearings and motor shaft, wherein rotor assembly is packed on the motor shaft, fore bearing chamber and rear bearing chamber are installed the rear and front end at rotor assembly respectively, the stator module device is in the outside of rotor assembly, the plastic packaging canning is in the outside of stator module, it is characterized in that above-mentioned fore bearing chamber and rear bearing chamber are the alternate structure of the opposite tongue and groove of coaxial openings, its center recess is the installation site of front and back bearings and respectively towards the rear and front end of rotor assembly.
The outboard cover of described rear bearing chamber is equipped with the bearing chamber case.
The described plastic packaging shell formation installation step that stretches out, installation step is provided with installing hole to satisfy the coupling installation requirement of various application apparatuss.
Described fore bearing chamber and rear bearing chamber are made by metal plate punching, or injection mo(u)lding.
Described bearing chamber case is made by metal plate punching, and its annular case is provided with the rib muscle of many indents to increase the intensity of bearing chamber case.
The utility model is because fore bearing chamber and rear bearing chamber are the alternate structure of the opposite tongue and groove of coaxial openings, its center recess is the installation site of front and back bearings and respectively towards the rotor assembly two ends, two bearings installation site distance is dwindled, thereby dwindled the span of front and back bearings greatly, make the internal structure of plastic packaging motor compact more, volume is more small and exquisite, has effectively reduced motor oscillating and noise; In addition, device has the bearing chamber case in the rear bearing outside, makes the utility model waterproof and anti-dust performance better, and simultaneously, the extended mounting structure of having optimized is installed coupling to be more prone to from the plastic packaging shell, and applicable surface is more wide.
