Abstract
The utility model relates to a permanent magnetic stepless speed-changing driving device which uses a magnetic pole filled with rare earth permanent magnet and a polar body to form relative displacement change to achieve the speed-changing purpose. The utility model is characterized in that an input shaft is connected with the magnetic pole, and an output shaft is connected with the polar body; the rare earth magnetic steel is regularly arranged on the polar body and the magnetic pole according to the number of pole pairs; the relative distance between the magnetic pole and the polar body can be changed through the polar body movement to achieve the purpose of stepless change. The utility model has no contact abrasion; the magnetic pole and the polar body automatic slide under the overload condition to avoid the workpiece being damaged; the utility model has the advantages of energy saving, safety, explosion protection, etc., and is suitable for various fields.
Description
The utility model relates to the infinitely variable speed transmission field, is the transmission device that variation that a kind of permanent magnetism magnetic pole and polar body are done relative displacement reaches the speed change purpose specifically.
The stepless speed changes devices (as the electromagnetic speed-adjusting Wechselstrommotor) that utilizes magnetic clutch to make at present, its shortcoming is that energy consumption is big, uses that nonferrous materials is many, gold machining is complicated, and with the device of magnetic actuator, can only transmission torque, can not stepless change.
The purpose of this utility model provides a kind of energy-conservation and saving nonferrous materials, the contactless wearing and tearing of gear, a kind of permanent-magnet stepless variable-speed driving device simple in structure.
Taked technological scheme by finishing above-mentioned purpose: the utility model is made up of two parts of driving mechanism and polar body displacement actuator.Driving mechanism is made up of input shaft, bearing and magnet steel.Polar body displacement actuator exports compositions such as bearing, key, housing by the worm and gear support of output shaft, polar body, magnet steel, bearing, pull bar, worm gear, worm screw, bearing support and the machine of execution.Its working principle is by worm and gear, and the key pull bar can make polar body do straight reciprocating motion, and polar body is by the permanent magnetic field of driving mechanism, by means of bearing and output shaft effect axle garden Zhou Yundong.As long as make the worm and gear transmission, make the pull bar moving linearly by key, can change the relative distance of the magnet steel of magnetic pole and polar body, thereby reach infinite variable speed purpose.
The utility model embodiment:
Fig. 1 is the utility model structural representation.
Fig. 2 is that magnetic pole and polar body cooperate figure.
According to illustrated in figures 1 and 2: input shaft 1 and output shaft 12 are coaxial.Magnet steel 14 is to be arranged in respectively regularly on polar body 4 and the magnetic pole 3 by number of pole-pairs, magnet steel 14 can be arranged on the polar body 4 separately by number of pole-pairs again regularly simultaneously, also can be arranged on the magnetic pole 3 regularly separately by number of pole-pairs, the magnet steel 14 of magnetic pole 3 and polar body 4 matches mutually, magnetic pole and polar body can be made plane shape respectively, taper, tubular.When tapered, its tapered edges is with axially angle can be selected from drawing by structural type in 0～90 ° of scope.Tapered edges is tubular when being 0 ° with axial angle, is plane shape when being 90 °.Polar body 4 is that displacement is held the worm and gear 7 that draws mechanism and can be done axial straight reciprocating motion according to polar body, to change the relative distance of magnetic pole 3 and polar body 4.
Utilize the magnetic pole 3 and the relative shift of polar body 4 to change its speed change of realization.The variation of relative shift is held by polar body and is drawn mechanism and realize, be equivalent to common magnetic clutch like this, change the exciting curent size and reach how much change magnetic flux, thereby change the variation purpose of input speed n1 and output speed n2, the utility model characteristics are to utilize the effect of permanent magnetism special magnet high magnetic fields, make solid of rotation with number of pole-pairs, produce the magnetic field coupling when rotated, hold under the effect of drawing mechanism in the polar body displacement, change two groups of distances between polar body, cause magnetic attraction to change, produce revolutional slip, thereby reach the speed governing purpose, as long as above-mentionedly mix suitable control wiring, just can become a cover automatic speed governing device.
The utility model is energy-conservation, and material-saving material, the contactless wearing and tearing of gear are in the feelings of excess load Condition lower magnetic pole 3 and polar body 4 skid automatically, avoid parts to damage because of excess load, can not demagnetize because of above-mentioned skidding simultaneously, can be widely used in weaving, printing, papermaking, cement, plastics, rubber, metallurgical mine, field of petrochemical industry.
