The utility model mainly solves the assembling quality problem of the motor. The motor comprises a shell containing the stator coils, a rotor and a shell of a rotor axle; the utility model is characterized in that the shell consists of a front end cover and a rear end cover which are symmetrically arranged and closely connected together; the external side of every end cover is provided with a small cover which is riveted on the corresponding end cover; the small cover is buckled on the external side of a bearing chamber in the end cover; the outside diameter of the small cover is closely matched with the inner diameter of the installation casing; the front and the rear end covers as well as the small cover are provided with a homocentric central hole; the rotor axle passes through the front and the rear end covers and the central hole of the small cover; an installation support is fixed on the installation casing. The structure of the utility model can reduce the parts, decrease the production procedures, increases the production efficiency, ensures the assembling quality of the motor and saves materials. The utility model is mainly suitable for the centralized air-conditioner.

Description

Casing and end cap integral type central air-conditioning motor

Technical field

The utility model relates to a kind of central air-conditioning motor, belongs to household electrical appliance motor production technical field.

Background technology

Central air-conditioning has been a requisite facility in office buildings, factory, market, the public place of entertainment, the output of central air-conditioning motor is also in continuous increase, because (inferior surface of machine case is the electric capacity box to the special mounting mode of central air-conditioning motor, there is mounting bracket on the aluminium end cap both sides), manufacturer all adopts casing 1 to add the structure of aluminium end cap 2, as Fig. 1, the electric capacity box can be attached on the casing more closely like this, two outstanding platforms of the aluminium end cap bearing chamber outside are just in time put two installation sleeves, and mounting bracket utilizes geometrical clamp to be connected with installation sleeve.

During production, on the general assembly line stator line bag pressure is gone in the casing, an aluminium end cap is installed earlier, put into rotor again, then another aluminium end cap is closed, also will utilize the long screw screw hole aligning of end cap up and down, could tighten screw like this, operation is more again, and operation is difficult, iron core is when being pressed into casing, and line contains easy run-off the straight, makes the casing distortion, close behind the end cap, decentraction between two end cap bearing chamber and the casing causes the rotor friction easily, produces noise.This structure not only influences production efficiency, and quality also is not easy to guarantee.

The utility model content

In order to solve the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of casing and end cap integral type central air-conditioning motor, and it can guarantee the assembly quality of motor effectively.

The technical solution of the utility model is, casing and end cap integral type central air-conditioning motor, comprise and contain stator line bag, the housing of rotor and armature spindle, it is characterized in that described housing is by before symmetrically arranged, rear end cap is fastenedly connected and forms, outside each end cap, be provided with and be riveted on the little buckle closure that respective end covers, little buckle closure is buckled in end cap bearing outside, little buckle closure external diameter size closely cooperates with the installation sleeve internal diameter size, before, the little buckle closure of rear end cap and setting thereof has concentric centre bore, before armature spindle passes through, the centre bore of rear end cap and little buckle closure thereof, the installation sleeve external fixation is provided with installing rack.

The further technical scheme of the utility model is, is provided with the seam positioning table on the medial surface of front end housing or rear end cap, and stator line bag side contacts with this seam positioning table.

The beneficial effects of the utility model are: after having adopted the utility model structure, change three traditional body structures into two body structures, utilize two end cap to replace casing and aluminium end cap, reduced by parts, reduced one procedure, not only do not influenced installation, and tube has been changed operation, improve production efficiency, guaranteed the assembly quality of motor, saved material.

Description of drawings

Fig. 1 is existing central air-conditioning motor structural representation;

Fig. 2 central air-conditioning of the present utility model motor structural representation;

Fig. 3 front end housing master of the present utility model cutaway view;

Fig. 4 is the left view of Fig. 3.

Among the figure: 1 casing, 2 aluminium end caps, 3 armature spindles, 4 rotors, 5 stator line bags, 6 rear end caps, 7 installing racks, 8 seam positioning tables, 9 front end housings, 10 installation sleeves, 11 little buckle closures.

Embodiment

As shown in Figure 2, casing and end cap integral type central air-conditioning motor comprise that stator line bag, rotor and armature spindle etc. are same as the prior art.

Housing is fastenedly connected by symmetrically arranged front end housing 9, rear end cap 6 screw by four M4*10 and forms, be provided with riveted joint preceding little buckle closure 11 thereon in front end housing 9 outsides, be provided with riveted joint preceding little buckle closure 12 thereon in rear end cap 6 outsides, little buckle closure is buckled in the corresponding end cap bearing chamber outside, and little buckle closure external diameter size closely cooperates with installation sleeve 10 internal diameter sizes.The little buckle closure of forward and backward end cap and setting thereof has concentric centre bore, and armature spindle 3 is by the centre bore of forward and backward end cap and little buckle closure thereof, and the installation sleeve external fixation is provided with installing rack 7.Rotor 4 is fixed on the armature spindle 3.The little buckle closure structure of forward and backward end cap and setting thereof is seen Fig. 3, Fig. 4.

Be provided with seam positioning table 8 on the medial surface of front end housing or rear end cap, stator line bag 5 sides contact with this seam positioning table.During installation, 8 pairs of stator lines of seam positioning table bag 5 has positioning action, prevents that stator line bag 5 from tilting.

During general assembly, stator line bag 5 is pressed in the front end housing 9, puts into rotor 4 again, rear end cap 6 is installed then, because front end housing 9 has adopted the seam locate mode, stator line bag pressure is fashionable, the iron core end face contacts with the stopping table position, and the pressure when having avoided stator core to be pressed into is oblique, presses phenomenon.Because of changing two body structures into, reduced on the general assembly line end cap operation has been installed together, and the two end cap position of mounting hole together, installing hole is not easy dislocation, screw has also been changed into the screw of M4*10 by M4*105, the distance between the two bearings chamber shortens, and axiality is higher, improve the qualification rate of product, improved production efficiency.Through installation testing, performance index such as noise, vibration all meet user's designing requirement, and are better than the traditional structure motor.
