Abstract

The utility model discloses a hammering motor comprising bearings, bearing chambers, a rotor shaft, a rotor, a stator, a front end cover, a rear end cover, and a metal insert. The rotor shaft having the rotor is installed on the bearings and passes through the internal portion of the stator, wherein the rotor shaft is concentric with the stator. The buckled front end cover and the buckled rear end cover are arranged at two ends of the stator. The bearing chambers are arranged inside the end covers and the bearings are arranged inside the bearing chambers. The metal insert is arranged in the front end cover and is concentric with the bearing chambers. Besides, the front end cover, the bearing chambers, the bearings and the metal insert are integrated into one. According to the utility model, the front end cover, the bearing chambers, the bearings and the metal insert are integrated into one; and the bearing is formed by direct injection molding into the end covers during the injection molding process. Because the integrated mode enables the surrounding pressures are large, reliable connection between the metal insert and the front end cover as well as reliable connection between the bearing chambers and the bearings can be ensured; the service life of the motor can be prolonged; and the motor quality as well as the security performance can be enhanced.

Description

A kind of motor that beats

Technical field

The utility model relates to a kind of motor, particularly a kind of motor that beats.

Background technology

In the prior art, be used for the tapping massager of body part massage, its employed motor that beats; Mainly be to constitute by bearing, armature spindle, rotor, stator, end cap, during fabrication, at first with end cap and bearing chamber injection mo(u)lding; Then bearing and end cap are assembled, promptly bearing is pressed into the bearing chamber in the end cap, and bearing chamber adopts nylon material to process usually through forcing press; Intensity and precision are all lower, because this motor assembling mode takes place to become flexible when end cap suction or variations in temperature easily, nylon material is when variations in temperature in addition; Mechanical performance changes also increasing thereupon, causes bearing and bearing chamber to come off easily, causes whole massage product failure; Influence user's result of use, brought potential safety hazard, wasted resource.

The utility model content

In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of motor that beats, and directly the copper sheathing mold insert is injection-moulded in the end cap during electric motor end cap injection moulding; Increased the bonding strength of bearing and end cap; Improve assembly precision, practiced thrift cost, prolonged electrical machinery life.

To achieve these goals, the technical scheme of the utility model is following:

A kind of motor that beats; Comprise bearing, bearing chamber, armature spindle, rotor, stator, front end housing, rear end cap; Armature spindle with rotor is installed on the bearing and to pass stator interior concentric with stator, and the stator two ends are provided with front end housing, rear end cap, the metal inserted piece of spiral-lock, establish bearing chamber in the said end cap; Bearing places bearing chamber; Said metal inserted piece places said front end housing and concentric with bearing chamber, and the integral body that said front end housing, bearing chamber, bearing, metal inserted piece are formed in one is avoided the gap occurring between bearing and the bearing chamber.

The beneficial effect of the utility model is that bearing is directly injection-moulded in the end cap when injection moulding, because pressure is bigger around integrated; Both guaranteed that metal inserted piece was connected with the reliable of front end housing; Increase the bonding strength of bearing and end cap again, improved assembly precision, practiced thrift cost; Prolong electrical machinery life, improved product quality and security performance.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure, 1, bearing, 2, bearing chamber, 3, front end housing, 4, stator, 5, rear end cap, 6, armature spindle, 7, rotor, 8, metal inserted piece.

Embodiment:

For the creation characteristic, the technological means that make the utility model and reach purpose and be easy to understand and understand, further set forth the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1; A kind of motor that beats comprises bearing 1, bearing chamber 2, armature spindle 6, rotor 7, stator 4, front end housing 3, rear end cap 5, metal inserted piece 8, and the armature spindle 6 with rotor 7 is installed on the bearing 1 and to pass stator 4 inner concentric with stator 4; Stator 4 two ends are provided with the front end housing 3 and rear end cap 5 of spiral-lock; Establish bearing chamber 2 in the said end cap, said bearing 1 places bearing chamber 2, and said metal inserted piece 8 places front end housing 3 and concentric with bearing chamber 2; The integral body that said front end housing 3, bearing Room 2, bearing 1, metal inserted piece 8 are formed in one; Since one-body molded, make bearing chamber bigger to the pressure of bearing all around, avoid the gap occurring between bearing and the bearing chamber.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.

Claims
