Description
Technical field
The present invention relates to a kind of modular ultrasonic clutch and braking device, this device is to utilize piezoelectric element to produce inverse piezoelectric effect, so as in conjunction with or separate driving element and drive element, to reach startup, to stop the function with engaging and disengaging gear such as speed change.
Background technique
Present known engaging and disengaging gear is of a great variety, can be divided into control type and automatic type by its control mode.The function of its engaging and disengaging gear has starting, stops, commutation, speed change or be used for axle and close or occasion such as separate with being coupling.The kind and the shortcoming thereof of its engaging and disengaging gear are as described below:
1, embedded engaging and disengaging gear: be to adopt the chimeric mode of tooth, tooth or key to come transmitting torque.The end face of its two connected members all has the tooth or the tooth of projection, if it is the tooth on driving element and the drive element or tooth is chimeric mutually or throw off, then can make driving and driven being coupling close or separate, but the situation of impact is arranged when engaging, so the speed discrepancy of two between centers should be unsuitable excessive.
2, friction type engaging and disengaging gear: be the engaging and disengaging gear that utilizes the frictional force transmitting torque.When engaging, driving element, can under certain pressure, compress from dynamic friction piece, when driving shaft rotates, can produce enough big frictional force between the mating face, with the rotation of drive driven shaft.This friction engaging and disengaging gear engages rapid with the speed of separating, and handiness, vibration and impact also lessly, but skidding can take place in its friction member during overload, so need often to adjust and replacing.
3, magnetic particle coupling: be to make the magnetic magnetization, form the magnetic chain with transmitting torque with field coil.When electric current increased, magnetic field strengthened, and then magnetic chain transmitting torque increases.This clutch on-off is rapid, running steadily, can make master and slave moving axis synchronously, have under speed discrepancy and the braking state and work; Skid by magnetic and can play overload protective function, be easy to realize stepless speed regulation by the control electric current, but electromagnetic interference is serious.
4, overrunning type clutch device: be motion of wedge action unidirectional delivery or the moment of torsion that utilizes the engagement of ratchet, ratchet or roller, module.When driving shaft counter-rotating or rotating speed were lower than driven shaft, engaging and disengaging gear just separated automatically, is a kind of directed engaging and disengaging gear.Engagement type simple in structure, but boundary dimension is big, under the separated state noise is arranged, and is usually used in the unessential occasion of low speed.
