Abstract
The utility model relates to a power conveying device for a garage door motor, which comprises a casing. A worm screw is arranged on an output shaft of a motor in the casing; two screw parts with opposite spiral direction are arranged on the worm screw; two worm wheels which are respectively engeaged with the two screw parts are arranged on the worm screw; drive gears which are coaxial with the worm wheels are respectively coaxially arranged on the two worm wheels; in addition, a gear which can simultaneously engaged with the two drive gears is arranged in the casing; a driving shaft which penetrate through and out of the casing is arranged on the shaft core of the gear. The utility model can counteract the movement of the worm screw caused by radial force and can improve the output effect of the dynamic force dynamic of a motor.
Description
The utility model is about a kind of motor actuator, refers to a kind of actuating unit that is used in the motor on the iron rolling door especially.
Motor is a kind of quite widely used power take-off, motor can be with power with certain rotating speed output, drive the device start that is linked, reach the operation purpose and the effect of expection, on the output shaft of motor, tend to be provided with again a transmission device as another, can reach difference in functionalitys such as output turns to, deceleration by this transmission device, as shown in Figure 3, be a kind of applicable transmission device at iron rolling door motor.
Transmission device as shown in Figure 3 mainly is to include a worm screw 30 with the coaxial interlock of motor 20 output shafts, be provided with in addition one with the worm gear 32 of worm screw 30 engagement, so through the cooperate transmission of worm screw 30 with worm gear 32, can cooperate the operation that furls by this with the outputting power of motor 20 by the transmission shaft output coaxial with worm gear 32 as devices such as garage rolling doors.
Yet this available dynamic transmission device, though can reach the purpose that transmission and deceleration should be arranged, but when seeing through worm screw 30 and worm gear 32 drive motor power, 32 on worm screw 30 and worm gear can generate a radial force and cause worm screw 30 to generate elastic moving, so not only can influence the transmission efficiency of 32 on worm screw 30 and worm gear, the output shaft of motor also can be driven and telescopic moving by worm screw 30 simultaneously, and therefore causes the damage of motor internals.
The purpose of this utility model is to provide the actuating unit of a kind of garage door with motor, can offset radial force, improves transmission efficiency, and avoids motor to damage.
The technical solution of the utility model provides the actuating unit of a kind of garage door with motor, it is characterized in that: it includes a housing that is combined on the motor, motor output shaft in the housing is provided with a worm screw, this worm screw is provided with two screw sections that are the opposite helical direction, in housing, be provided with again two respectively with the worm gear of this two screw section engagement, and two worm gears are to be separately positioned on two side positions of worm screw, on two worm gears coaxial, then respectively be provided with a driving gear coaxial with this worm gear, in housing, be provided with one and this two driving gears while meshed gears in addition, the transmission shaft that always passes housing then is set on the axle center of this gear.
The utility model can be offset the generation of radial force, and can improve the transmission efficiency between worm and wheel, and avoid the damage of motor internals by the screw section of two different rotation directions on the worm screw, improves the working life and the effective utilization of motor.
Further specify structure characteristic of the present utility model and purpose below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is a generalized section of the present utility model.
Fig. 3 is a kind of generalized section of existing motor power transmission device.
The utility model mainly is about the actuating unit of a kind of garage door with motor, please referring to Fig. 1,2, by seeing among the figure, motor power transmission device of the present utility model, mainly be to include a worm screw 10 with the coaxial interlock of motor 20 output shafts, be provided with two screw sections 102 that are the opposite helical direction in worm screw 10,104, in the housing of transmission device, be provided with again two respectively with 10 liang of screw sections 102 of worm screw, the worm gear 16 of 104 engagement driving, 17, in two worm gears 16,17 coaxial on respectively be provided with one with worm gear 16, the driving gear 162 of 17 coaxial interlocks, 172, two worm gears 16 wherein, the 17th, be separately positioned on the both sides of worm screw 10, so can allow two worm gears 16,17 through two different spiral shells to screw section 102, after 104 transmissions, has identical sense of rotation, transmission device more includes one and two driving gears 162 in addition, 172 while meshed gears 12 are provided with the transmission shaft 14 that always passes housing on the axle center of gear 12.
By above-mentioned transmission device, two screw sections 102,104 that the outputting power of motor 20 can see through worm screw 10 are delivered to respectively on two worm gears 16,17, two worm gears 16,17 are rotated in the same way, and then the driving gear 162,172 that sees through two coaxial interlocks is passed to outputting power on gear 12 and the output shaft 14, by these output shaft 14 outputs, so just can see through continuous action devices such as the cable wire that is arranged on the output shaft 14, chain, drive as structure starts such as garage rolling doors, and reach the operating effect of expection.
This moment, the outputting power of Yin Mada 20 was that transmission is come in the screw section 102,104 that sees through two different rotation directions on the worm screw 10, so worm screw 10 is when transmission, can radial force be cancelled out each other because of the reversing drive effect of two screw sections 102,104, so not only can allow worm screw 10 and 16,17 on worm gear reach good transmission effect, and can avoid worm screw 10 that the phenomenon of telescopic moving takes place when start, and then avoid the damage of motor 20 internals, the working life of improving motor 20.
