Abstract
The utility model discloses a rotating shaft structure of a brushless dc motor. The rotating shaft structure comprises a rotating wheel, an electric drum brake detent, a waist-shaped pad, a rotating stop sheet, a fixing sheet and a flange nut, wherein the electric drum brake detent is sleeved on a rotating shaft of the rotating wheel, the waist-shaped pad tightly close to the electric drum brake detent is sleeved on the rotating shaft of the rotating wheel, the rotating stop sheet tightly close to the waist-shaped pad is sleeved on the rotating shaft of the rotating wheel, the fixing sheet is sleeved on the rotating shaft of the rotating wheel for fixing the rotating stop sheet, and the flange nut fixedly fastens the electric drum brake detent, the waist-shaped pad, the rotating stop sheet and the fixing sheet on the rotating shaft. Compared with the prior art, the rotating shaft structure of the brushless dc motor has a compact and reasonable structure, can prevent the rotating shaft of the brushless dc motor from being worn and prolongs service life.
Description
Technical field
The utility model relates to motor device field, exactly refers to a kind of pivot structure of brushless DC motor.
Background technology
Brshless DC motor is made up of motor body and driver, is a kind of typical electromechanical integrated product.Brushless electric machine refers to the motor of brushless and commutator (or collector ring), claims again commutatorless machine.In the time being born motor last century, the practicality motor of generation is exactly brushless form, i.e. mouse cage AC formula asynchronous motor, and this motor is widely used.But asynchronous motor has many defects that cannot overcome, so that motor technology slower development.The middle of this century transistor that has been born, thereby adopt transistor commutating circuit to replace the DC brushless motor of brush and commutator just to arise at the historic moment.This Novel brushless motor is called electronically commutated direct current machine, and it has overcome the defect of first generation brushless electric machine.
Brushless DC motor is the one of permanent magnetic synchronous electrical motor, and is not real direct current machine, the English BLDC that is called for short.Brushless DC motor pictorial diagram has been different from brushless motor, brushless DC motor does not use mechanical brushgear, adopt square wave autocontrol permagnetic synchronous motor, replace carbon brush commutator with Hall element, permanent magnetic material using neodymium iron boron as rotor, in performance, comparing general traditional direct current machine and have great advantage, is current optimal buncher.
At present, the pivot structure of existing brushless DC motor is reasonable not, causes the rotating shaft of brushless DC motor easily to wear and tear, and shorten useful life.
Utility model content
For above-mentioned defect, the technical problem that the utility model solves is to provide a kind of pivot structure of brushless DC motor, and compact conformation is reasonable, and rotating shaft wearing and tearing that can brushless DC motor, extend its useful life.
In order to solve above technical problem, the pivot structure of the brushless DC motor that the utility model provides, comprise runner, the electricity bulging brake that rubs, kidney-shaped pad, spline sheet, stator and flange nut, wherein, the described electricity bulging brake that rubs is socketed in the rotating shaft of described runner, described kidney-shaped pad is close to the described electricity bulging brake that rubs and is socketed in the rotating shaft of described runner, described spline sheet is socketed in the rotating shaft of described runner by described kidney-shaped pad, described stator is socketed in the rotating shaft of described runner and fixes described spline sheet, described flange nut is by the described electricity bulging brake that rubs, kidney-shaped pad, spline sheet and stator are locked in the rotating shaft of described runner.
The recess width of preferably, overlapping lace on described runner is 24mm.
Preferably, described flange nut is retaining hexagonal flange nut.
The pivot structure of the brushless DC motor that the utility model provides, comprise runner, the electricity bulging brake that rubs, kidney-shaped pad, spline sheet, stator and flange nut, wherein, the described electricity bulging brake that rubs is socketed in the rotating shaft of described runner, described kidney-shaped pad is close to the described electricity bulging brake that rubs and is socketed in the rotating shaft of described runner, described spline sheet is socketed in the rotating shaft of described runner by described kidney-shaped pad, described stator is socketed in the rotating shaft of described runner and fixes described spline sheet, described flange nut is by the described electricity bulging brake that rubs, kidney-shaped pad, spline sheet and stator are locked in the rotating shaft of described runner.Compared with prior art, the pivot structure of the brushless DC motor that the utility model provides, compact conformation is reasonable, and rotating shaft wearing and tearing that can brushless DC motor, extend its useful life.
