Abstract
Disclosed is a monoblock type external rotor asynchronous motor end cap, comprising an end cap body, installing sheets extending from the end cap body, screw holes arranged in the installing sheets, a circular ring type projection arranged at the central section of the internal surface of the end cap body, a bearing chamber arranged at one end of the end cap body corresponding to the projection, and radiating ribs arranged upon the internal surface of the end cap body. The end cap of the utility model, with a reasonable and firm structure, facilitates the cooperation with motor casing installation, overcomes the defects of loose connection between the mandrel and the end cap caused by using the screw for connection as well as the damage to the motor and the reduced performance of the motor resulting from the poor concentricity caused by poor assembling and processing, and makes the motor generate no vibration and no noise during operation. The internal surface of the end cap body is provided with radiating ribs which are evenly distributed around the projection, thereby ensuring excellent heat radiation effect and prolonging the service lifetime of the motor.
Description
Technical field
The utility model relates to a kind of asynchronous machine end cap, particularly a kind of integral type external rotor asynchronous machine end cap.
Background technology
At present; The external rotor asynchronous machine 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.
Summary of the invention
The purpose of the utility model just is to provide a kind of processing cost low, high efficiency, and performance is good, and screw is difficult for loosening integral type external rotor asynchronous machine end cap.
To achieve these goals; The technical scheme that the utility model adopts is such: the integral type external rotor asynchronous machine end cap of the utility model, comprise the end cap body, and said end cap body is provided with outward extending installation sheet; Installation sheet is provided with screw; End cap body internal surface middle part is provided with the convexity of an annular, and an end of protruding corresponding end cap body is provided with bearing chamber, and the end cap body internal surface also is provided with radiating ribs.
As preferably, said end cap body internal surface is provided with draw-in groove near the edge.
As preferably, be provided with reinforcement between the side of said convexity and the end cap body.
As preferably, said reinforcement is four, evenly is arranged on the end cap body.
As preferably, said radiating ribs evenly is arranged on around the convexity.
As preferably, said convexity, installation sheet and this body by integral forming of end cap.
Compared with prior art; The advantage of the utility model is: this end cover structure is reasonable in design; Overall structure is firm, installs with motor case to cooperate conveniently, uses axle and end cap to be connected through screw to be prone to loosening and to assemble and process the shortcoming that does not reach that concentricity causes the shortcoming of motor damage and motor properties caused reduction thereby solved; Make motor in use can not produce vibration, also can not sound; The end cap body internal surface is provided with radiating ribs, and radiating ribs evenly is arranged on around the convexity, good heat dissipation effect, the useful life of growth motor; Be provided with reinforcement between protruding side and the end cap body adding stiff stability, protruding, installation sheet and this body by integral forming of end cap, easy to process, and the machining accuracy height.
