Abstract
The utility model relates to a gear motor which comprises an enclosure, a motor arranged at the enclosure, a gear speed variation unit connected with the output shaft of the motor, wherein a bearing is arranged at the enclosure and connected fixedly with a sector gear which meshes the end gear of the gear speed variation unit; a microswitch, positioned at certain angle, is arranged at the enclosure to fit two lateral sides of the section gear. After the action of speed reduction made by the gear speed variation unit, the output shaft of motor can drive the sector gear for a motion; and the microswitch can control the sector gear for a reciprocating motion so that the bearing can finally rotate on the enclosure. At this time, the reciprocating motion of a valve can be realized by fixing the rotary shaft of the valve at the bearing. The utility model has the advantages that the power output terminal of the gear motor can perform a reciprocating motion and such a gear motor can control the device including a water valve for a continual opening and closing.
Description
Technical field
The utility model relates to gear motor, mainly is the reciprocating gear motor of a kind of control.
Background technology
At present, gear motor is widely used in various fields.General gear motor is to connect one group of reduction gearing at motor output shaft, and it can be applied to various occasions after slowing down to make the power of output shaft.And some occasion, such as water valve, valve need constantly be opened, be closed, and so just requires the clutch end of gear motor can satisfy reciprocating motion, and existing gear motor does not possess this function.
Summary of the invention
The utility model will solve the defective of above-mentioned prior art, and a kind of gear motor of clutch end energy automatic reciprocating motion is provided.
The utility model solves the technical scheme that its technical problem adopts.This gear motor comprises housing, is located at the motor on the housing, and with the speed change gear that the output shaft of motor is connected, housing is provided with bearing, and bearing is connected with sector gear, and this sector gear is meshed with the terminal gear of speed change gear; Housing is provided with the sensitive switch that matches with the dual-side of sector gear, and sensitive switch is placed at an angle.The rotating speed of motor output shaft drives the sector gear motion after geared system slows down, the control by sensitive switch just can make the sector gear reciprocating motion, thereby finally causes bearing to rotate on housing.This moment, the rotating shaft with valve was fixed on the reciprocating motion that just can realize valve on this bearing.
The effect that the utility model is useful is: the clutch end of gear motor can be realized reciprocating motion, can control devices such as penstock with such gear motor and constantly open, closes.
Description of drawings
Fig. 1 is that master of the present utility model looks cross-sectional view;
Fig. 2 is a plan structure schematic diagram of the present utility model;
Among the figure: 1-motor output shaft, 2-pinion, 3-gear wheel, 4-sensitive switch, 5-positive stop, 6-bearing, 7-contact, 8-sector gear, 9-housing, 10-motor.
Embodiment
Below in conjunction with accompanying drawing introduction is done into-gone on foot to the utility model: accompanying drawing is the internal structure schematic diagram after housing 9 is opened
This gear motor, comprise housing 9, be located at the motor 10 on the housing 9, the speed change gear that is connected with the output shaft 1 of motor 10, this is taken turns speed change gear and is made up of five intermeshing transition gears, transition gear comprises coaxial gear wheel 3 and pinion 2, the gear wheel 2 of first transition gear and the driving gear engagement on the motor output shaft 1, the gear wheel engagement of pinion and second transition gear, the pinion of second transition gear again with the engagement of the gear wheel of next transition gear, so just can realize slowing down step by step.Housing 9 is provided with bearing 6, and bearing 6 can rotate on housing 9, and the size of bearing 6 its axis holes adapts with the axle that needs to be connected.Bearing 6 is connected with sector gear 8, and this sector gear 8 is meshed with the terminal gear of speed change gear; Housing 9 is provided with the sensitive switch 4 that matches with the dual-side of sector gear 8, and sensitive switch 4 is placed at an angle.Sector gear 8 both sides have the contact 7 that cooperates with sensitive switch 4.Housing 9 is provided with the positive stop 5 that cooperates with sector gear 8.The angle of two sensitive switch 4 placements can determine the hunting range of sector gear 8.Positive stop 5 also can limit the hunting range of sector gear, to reduce the collision of 8 pairs of sensitive switches 4 of sector gear.Though sector gear 8 is spacing by positive stop 5, sensitive switch 4 can just be opened in contact 7.Sensitive switch 4 its circuit are connected with motor, motor backward rotation when sensitive switch 4 is touched, the also counter motion thereupon of motor counter-rotating back sector gear 8.
During use, the rotating shaft of devices such as valve is fixed in bearing 6.Allow motor 10 rotate, thereby drive sector gear 8 swings by transition gear deceleration, transmission, bearing 6 is rotated, the rotating shaft that is fixed in bearing 6 like this is just movable, thereby realizes the unlatching of valve or close.When sector gear 8 swings to a certain degree, sensitive switches 4 are touched in contact 7, and the control by circuit makes motor 10 counter-rotatings, and sector gear 8 counter motion thereupon is fixed in the also counter motion of axle of bearing 6 this moment.When sector gear 8 swings to a certain degree, touch sensitive switch 4 again, sector gear 8 begins counter motion immediately again.Like this, the clutch end of gear motor just can be controlled the reciprocating motion of other devices, for example this need of the penstock device of constantly opening, closing.
