Background technology
Stepping motor is exactly a kind of actuator that is angular displacement by electroporation; When step actuator receives a pulse signal, it rotates a fixing angle with regard to Driving Stepping Motor by the direction of setting.We can control by the number of control impuls the angular displacement of motor, thereby reach pinpoint object; Can also control speed and the acceleration that motor rotates by control impuls frequency simultaneously, thereby reach the object of speed governing.At present, more conventional stepping motor comprises variable reluctance stepping motor (VR), permanent-magnet stepping motor (PM), hybrid type stepping motor (HB) and single-phase type stepping motor etc.
The difference of stepping motor and common motor is mainly just the form of its pulsed drive, this feature just, and stepping motor can combine with modern digital control technology.But stepping motor is all being not so good as the DC servo-motor of traditional closed-loop control aspect control precision, velocity variations scope, low-speed performance; Not extra high occasion so be mainly used in required precision.Due to stepping motor have simple in structure, reliability is high and cost is low, so stepping motor is widely used in the every field of production practices; Especially manufacture field at Digit Control Machine Tool, because stepping motor does not need A/D conversion, can directly digital pulse signal be transformed into angular displacement, so be considered to optimal Digit Control Machine Tool executive component always.
At present, the problem such as conventional stepping reducing motor exists transmission efficiency low, and energy consumption is large, and useful life is short, in addition, easily flies into the particles such as dust when rotation and causes wearing and tearing, has improved coefficient of friction.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, provide that a kind of transmission efficiency is high, energy consumption is low, stepping reducing motor.
In order to solve above-mentioned technical problem, basic solution technical scheme of the present utility model is: a kind of stepping reducing motor, and comprise columniform electric machine casing, and be arranged on the train of reduction gears of electric machine casing top, in described electric machine casing, be provided with stator and rotor,
Described electric machine casing comprises metal upper shell and metal lower shell, described rotor is supported in metal upper shell and metal lower shell by upper plastic bearing and lower plastic bearing, described lower plastic bearing is semienclosed plastic bearing, i.e. centre bore one end of this lower plastic bearing sealing;
Described train of reduction gears comprises the driven gear, idler gear and the deceleration output gear that are connected with a joggle successively; Described driven gear, idler gear and deceleration output gear are placed in a plastic casing, and described deceleration output gear connects an output shaft;
A circuit board is fixed in described electric machine casing outside, for being connected power supply is provided with extraneous power supply.
As a kind of improvement of the present utility model, described circuit board is provided with four welding endss, and is welded with four electric wires.
As another kind of improvement of the present utility model, the other end of described these four electric wires is welded in a plug.
The utility model further improves, and the shape of described plastic casing is consistent with the shape of electric machine casing; The top end face of this plastic casing is prismatic.
Further improvement of the present utility model, four pin places of described top end face respectively have a cylindrical hole.
Further improvement more of the present utility model, described output shaft connects a bevel gear.
The beneficial effects of the utility model are: train of reduction gears is set, it comprises the driven gear, idler gear and the deceleration output gear that are connected with a joggle successively, can play like this stable delivery power and play reduction velocity of rotation, improving transmission efficiency, reducing energy consumption.Adopt semi-enclosed plastic bearing, can prevent that the particles such as dust from entering, thereby extend the life-span of motor.
