Abstract
A kind of usefulness is equipped with the magnetic pole of permanent magnetic steel and polar body to be done relative displacement and changes the transmission device that reaches the speed change purpose, it is characterized in that power shaft links to each other with magnetic pole, output shaft links to each other with polar body, rare earth magnetic steel is arranged on polar body and the magnetic pole by number of pole-pairs is regular, can change the relative distance of magnetic pole and polar body by polar body displacement actuator, reach the stepless speed regulation purpose.Advantages such as the contactless wearing and tearing of the present invention are skidded automatically at the situation lower magnetic pole and the polar body of excess load, avoid parts to damage, and are safe in utilization, have safety, explosion-proof can be applicable to every field.
Description
The present invention 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 change device (as the electromagnetic speed-adjusting alternating current motor) that utilizes electromagnetic clutch to make at present, its shortcoming is that energy consumption is big, uses that nonferrous materials is many, metalworking is complicated, and with the device of magnetic actuator, can only the transmit force distance, can not infinitely variable speeds.
The purpose that the present invention proposes 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 technical scheme by finishing above-mentioned purpose: the utility model is made up of two parts of transmission mechanism and polar body displacement actuator.Transmission mechanism is made up of power shaft, bearing and magnet steel.Polar body displacement actuator exports compositions such as bearing, key, housing by the turbine worm support of output shaft, polar body, magnet steel, bearing, pull bar, turbine, scroll bar, bearing pedestal and the machine of execution.Its operation principle is by turbine worm, and the key pull bar can make polar body do straight reciprocating motion, and polar body is by the permanent magnetic field of transmission mechanism, by means of bearing and output shaft effect axle garden Zhou Yundong.As long as make the turbine worm 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 embodiment of the invention is described in detail in conjunction with the accompanying drawings.
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: power shaft 1 and output shaft 12 are coaxial.Magnet steel 14 is to be arranged in respectively regularly on utmost point spare 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 planar shaped respectively, taper, tubular.When tapered, its tapered edges is with axially angle can be selected from drawing by version in 0～90 ° of scope.Tapered edges is tubular when being 0 ° with axial angle, is planar shaped when being 90 °.Polar body 4 is that displacement is held the turbine worm 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 electromagnetic 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-intensity magnetic field, make rotary body 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 circuit, just can become a cover automatic speed governing device.
The present invention has energy-conservation, and material-saving material, the contactless wearing and tearing of gear are skidded automatically at the situation lower magnetic pole 3 and the polar body 4 of excess load, avoid parts to damage because of excess load, can not demagnetize simultaneously, can be widely used in weaving, printing because of above-mentioned skidding, papermaking, cement, plastics, rubber, metallurgical mine, field of petrochemical industry.
