Description
Technical field
The present invention relates to a kind of horizontal moving type engaging motor of architecture advances, exactly, relate to a kind of with architecture advances stator and rotor between the variation of magnetic resistance, electric energy is converted into mechanical energy, slide with the crosshead shoe that substitutes the foramen primum latch structure again and retrain under the secondary constraint, make rotor do circumferential translation, and drive the horizontal moving type engaging motor of inside engaged gear reducing gear, belong to the power-jdriven gear technical field in the mechanized equipment system by rotor around stator.
Background technology
In recent years, both at home and abroad obtained good progress in the research of novel reducing gear and motor being carried out aspect integrated.Such as the two combines design and makes motor and harmonic wave speed reducing machine, make output torque increase, and its physical dimension significantly reduce.The scientific and technical personnel of Japan adopt the deceleration transmission principle based on gears engaged, have developed the motor of multiple different types of structure.For example: the piezoelectricity cycloidal generator, it is that engagement by a pair of cycloid gear converts the stretching motion of piezoelectric actuator the rotation of rotor to, relies on the actuating force of piezoelectric actuator output to promote cycloidal generator rotation output torque again.The speed reducing ratio of piezoelectricity cycloidal generator is its rotor and the ratio of difference with the rotor number of teeth of the stator number of teeth, and speed reducing ratio is very high.Simultaneously little because of the friction loss of meshed transmission gear, transmission efficiency is high, so the ultrasonic harmonic motor that involves that frictional force is exported the slow-speed of revolution, high pulling torque between piezoelectricity cycloidal generator and the dependence rotor compares, and has higher efficient and useful life.
Because the transmission advantage of gears engaged, successively developed the multiple low-speed big motor that gears engaged is combined with dissimilar driver in recent years.For example the cycloidal generator that drives by rubber deformation, by the bevel gear motor of air cylinder driven, rely on face gear motor and electromagnetism cycloidal generator and electromagnetism bevel gear motor or the like of Driven by Hydraulic Cylinder.Above-mentioned motor has the efficient height, precision is good, wearing and tearing are little, volume is little, the advantage of compact conformation, has obtained good application at the drive unit that is used for robot.
But above-mentioned motor just interconnects driver and stator, do not constitute integrated mechanism, so structure is not compact.Adopt the motor of cylinder and Driven by Hydraulic Cylinder, except driver, also additionally need power source.The motor that piezoelectricity or giant magnetostrictive material drive is then lacked very much (only being micron order) because of the stroke of its driver effect, in order to satisfy the needs of stator movement stroke, also needs to increase a cover lever, to increase its effect stroke.And the motor that uses in the bigger occasion of driven at low speed and load all will be installed decelerator and associated components thereof or device, has so just increased the structure member and the weight of drive unit.For this reason, the applicant has developed and a kind of mechanical reduction gear and motor driver has been realized the integrated horizontal moving type engaging motor that combines (number of patent application: 200810114840.5), the above-mentioned various defectives of prior art have been solved preferably, but in use afterwards, find also to exist on its structure defective: its magnetic field is coupling and generation negative work magnetic circuit easily, circuit control more complicated, the required precision height of the machining of individual parts and assembling, therefore how to improve above-mentioned motor, to improve and to improve its electrical and mechanical comprehensive performance, just become applicant's the new problem of research.
