Double rolling key clutch utilizes the velocity variations of driving and driven part or the conversion of sense of rotation, has the clutch of clutch function voluntarily.Be the basic part in electromechanical integration mechanical transmission, be generally used for one direction transmission torque, the torque in positive and negative two directions of driving shaft can be transmitted to follower by it, and when driving shaft is in halted state, and the torque that follower is formed cannot reversely be transmitted.In prior art, double rolling key clutch structure is more complicated, and cost is higher.
Notification number is that the Chinese utility model patent of CN201557947U application discloses that a kind of novel clutch, by the fixed base comprising upper fixed seat and lower fixed seat, driving shaft, driven axle and passive reel, magnetic sour jujube pearl, price fixing formed, its upper fixed seat and driven axle phase fit, lower fixed seat and driving shaft phase fit, passive reel inner chamber is equipped with shift fork, the front end of driving shaft connects with shift fork, adsorption has the price fixing of magnetic sour jujube pearl to be fixed on lower fixed seat surface, packing ring is placed in the centre of price fixing and shift fork, during use, shift fork promotes magnetic sour jujube pearl, magnetic sour jujube pearl promotes driven axle dribbling and moves driven axle synchronous rotary, when with when manually pulling curtain, by belt pulley, driven axle is rotated, magnetic sour jujube pearl leaves passive reel groove, passive reel is separated with shift fork and driving shaft, reach the one-way transmission object of power, the switching function of curtain manual can not be had influence under the situation had a power failure or break down.
Publication number is that the Chinese utility model patent of CN103591182A application discloses that a kind of double rolling key clutch, it comprises driving shaft, follower and roller, described driving shaft termination is provided with the shifting block rotated with driving shaft, the recessed inner ring of described shifting block is formed with arc groove, described roller is cylindrical, described arc groove is the circular arc adapted with roller profile, when described roller is arranged in arc groove, the work side of described shifting block is crossing with the normal plane of the tangent line of the tangent formation in roller outer periphery and the arc-shaped surface of arc groove, its controlling method be separated is while the reversion of control driving shaft, detect the state of follower, until detect that follower stopped reversion.
The poor stability of above-mentioned existing clutch, sour jujube post is easily toppled over, and the friction on magnet and chassis is serious, and working life, short grade was not enough.
[model utility content]
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of curtain motor clutch.
The purpose of this utility model is achieved through the following technical solutions: a kind of curtain motor clutch, comprise driving shaft, catch bar, rotating disk and sour jujube post, described driving shaft is provided with the catch bar rotated with driving shaft, described rotating disk comprises concave ring part, the recessed inner ring of described concave ring part is provided with arc groove, described catch bar is arranged in the recessed inner ring of concave ring part, described catch bar is provided with and promotes side, described sour jujube post is arranged in the room of catch bar and the restriction of recessed inner ring, described sour jujube post is erected on chassis, described sour jujube post is connected by magnetic with between chassis, described chassis is static and vertical with described driving shaft, it is characterized in that: the catercorner length of the axle section of described sour jujube post is greater than the cavity height that recessed inner ring and chassis are formed, and can improve stability like this, and not easily topple over, and can reduce the friction on magnet and chassis, not easy to wear.
Described sour jujube post comprises hollow cylinder and the magnet of single-open, and described magnet is placed in the inner chamber of described hollow cylinder, and the height of inner chamber is greater than the height of magnet, avoids magnet to be worn.
Described inner chamber is cylindrical cavity, and described magnet is cylindrical body.
Also comprise base and the base cover with base engagement, described rotating disk arranges induction installation, described base arranges the sensor for receiving induction installation.Described induction installation can be magnet, and corresponding sensor can be magnetic inductor.
