Abstract
A screw motor is a motor which can convert electric energy into linear motion mechanical energy and comprises a lengthened stator and a shell, the shell and the stator are provided with slots along the axial direction, a rotor is hollow and is not lengthened, the shaft of the rotor is a screw rod shaft fixed on the end cover of the motor shell, the rotor and the screw rod shaft are connected by threads, the two ends of the rotor are respectively provided with a bearing, the outer edges of the bearings are respectively provided with a shifting fork, the end parts of the two shifting forks are fixedly connected with a beam which is positioned in the slot of the motor shell and can linearly slide in the slot. The rotor can do spiral movement on the screw rod shaft under the action of electromagnetic force, and the shifting fork beam is driven to output power externally by the bearings and the shifting fork. The shifting fork beam plays the role of magnetic conduction while outputting power externally, thus guaranteeing the integrity of the part of the shell coupled with the rotor and a stator magnetic circuit. The screw motor has the advantages of being directly used as the power source for linear motion, and having higher acceleration and energy conversion efficiency.
Description
Affiliated technical field
Patent of the present invention relates to a kind of device that converts electrical energy into rectilinear motion mechanical energy, relates to screw motor furtherly.
Background technology
At present, existing motor has electric rotating machine and linear electric motors according to relative motion mode branch.Electric rotating machine efficient is higher, power supply control is simple, but produce the output of straight line power, then need configuration to rotatablely move and be converted to straight-line device, make the motion parts quality of package unit strengthen, acceleration and efficient reduce, and this shortcoming was especially obvious when move distance was longer.Use linear electric motors to save and be converted to straight-line mechanical device with rotatablely moving, directly export straight line power, the moving-mass of system is little, and acceleration is bigger, but the efficient of linear electric motors is lower, and linear motor needs complicated power supply control apparatus.
Summary of the invention
In order to solve existing power source for linear motion energy conversion efficiency and the lower problem of acceleration, patent of the present invention provides a kind of motor, this motor has the efficient identical with turning motor, and direct linear movement output power, has higher acceleration.
It is to develop from electric rotating machine that patent of the present invention solves the technical scheme that its technical problem adopts: the stator of motor and housing lengthening, fluting vertically.Motor shaft changes the lead screw shaft on the electric machine casing end cap of being fixed on that is positioned on the housing axis into.Rotor hollow, do not extend, adopt with lead screw shaft to be threaded.Two ends of rotor is installed bearing, and the outer rim of bearing is installed shift fork, and the end of two shift forks and a crossbeam are fixed together, and crossbeam is arranged in the groove of electric machine casing, can slide in groove.Crossbeam plays the magnetic conduction effect simultaneously, the integrality of that part of housing magnetic circuit of assurance and rotor coupling.The rotor motion of spinning on lead screw shaft under the electromagnetic force effect drives shift fork and crossbeam by bearing, and crossbeam is slided and external outputting power at the enclosure slot cathetus.
The beneficial effect of patent of the present invention is as power source for linear motion, to have higher accelerations owing to moving-mass is less, and have the energy conversion efficiency identical with electric rotating machine.
