Abstract
Disclosed in the utility model is an end cap for a motor. The end cap includes an end cap main body; an iron core shaft sleeve that is perpendicular to the inner wall of the end cap main body is arranged in the middle of the inner wall of the end cap main body, wherein the iron core shaft sleeve has a hollow structure; bearing chambers are respectively arranged at two ends of the iron core shaft sleeve and bushes are arranged at the inner walls of the two bearing chambers; and a circular ring-shaped boss front edge is arranged at the middle outside the end cap main body. According to the utility model, the end cap main body and the iron core shaft sleeve form an integrated structure by one-time die-casting moulding or one-time pouring moulding, thereby substantially simplifying the processing procedures of the end cap and enabling the assembling of the motor to become convenient; moreover, the concentricity of the end cap can be ensured, thereby effectively ensuring the whole concentricity of the motor and thus completely solving the concentricity problem of an outer rotor motor.
Description
Technical field
The utility model relates to a kind of end cap, and particularly a kind of motor is used end cap.
Background technology
At present; The asynchronous motor of outer rotor of known integral type end cap mainly concentrates on low-power machine; Power is no more than 1KW, the mode that is to use a single mandrel and end cap to be connected with seam that powerful whole external rotor electric machine adopts through bolt, and this kind connected mode is owing to exist two workpieces; Be prone to exist morpheme sum of errors rigging error in processing and fit on, must make whole concentricity and position degree guarantee to require to increase; Process and assemble the air gap inequality that is prone to cause motor not in place, make motor produce rotor and wipe mutually and damage, also be prone to cause motor to produce electromagnetic noise and vibration owing to air gap is uneven; Motor properties is degenerated, when using bolts assemblies, because bolt must bear the vibration in whole weight of motor and the motor use; Be prone to make the bolt looseness of motor, thereby motor is damaged, owing to increasing of processing component; The processing cost of motor is improved, reduce work efficiency.Prior electric machine end cap all adopts the cast iron manufacturing; Its central through hole is directly to be provided with rolling bearing in the bearing chamber; Because the cast iron self property determines that motor is in the long operating time, the dimensional accuracy of bearing chamber just changes under the rotating shaft effect of high speed rotating; Cause the requirement of noise, vibrations overshoot, motor seize accident also can take place when serious.
Summary of the invention
The purpose of the utility model just is to provide a kind of processing simple in structure, easy, good rigidly, long service life, and the motor of installation, convenient disassembly is used end cap.
To achieve these goals; The technical scheme that the utility model adopts is such: the motor of the utility model is used end cap, comprises the end cap body, and said end cap inner body wall middle part is provided with the unshakable in one's determination axle sleeve vertical with its inwall; Axle sleeve unshakable in one's determination is a hollow structure; And axle sleeve unshakable in one's determination two ends are respectively arranged with bearing chamber, and the two bearings chamber interior walls is provided with lining, and end cap body exterior middle part is provided with the boss seam of annular.
As preferably, said end cap body edge is provided with installation sheet, and installation sheet is provided with bolt mounting holes.
As preferably, said axle sleeve unshakable in one's determination is provided with the reinforcement that is connected axle sleeve unshakable in one's determination and end cap body with end cap body junction.
As preferably, said axle sleeve unshakable in one's determination and end cap body are through die casting or pour into a mould one-body molded.
Compared with prior art; The advantage of the utility model is: the utility model makes end cap body and axle sleeve unshakable in one's determination be integrally formed structure, thereby has simplified the procedure of end cap greatly through die casting or pouring one-step forming; Make the assembling of motor simpler; And can guarantee the concentricity of end cap, and then the whole concentricity of motor is effectively guaranteed, thoroughly solve the concentricity problem of outer rotor motor; The utility model adopts the iron and steel manufacturing, has enough mechanical strengths, and the bearing chamber inwall is provided with lining; The mechanical shock that is caused when ability support rotor and rotation thereof reaches certain protective action, and can guarantee has enough protective effects to winding and rotary body; And it is simple in structure, easily manufactured.
