Abstract
A kind of permanent magnetic speed-adjusting mechanism that the utility model provides, comprises power shaft, output shaft, magnetic conductive disk, permanent magnet, round shape fixed disk, support and annulus plate-like permanent magnet fixed disk.Wherein, magnetic conductive disk is that odd number to be evenly fixedly installed on power shaft and coaxial with power shaft at equal intervals; Annulus plate-like permanent magnet fixed disk is made up of the fan-shaped fixed head be spacedly distributed and is placed in the middle of the interval that formed by two adjacent magnetic conductive disks; The fan-shaped fixed head that bilateral symmetry is fixed with permanent magnet is fixedly mounted on support.The speed adjusting gear of this kind cartridge type achieves the radiai adjustment of coupled relation between permanent magnet and magnetic conductor, without the need to axial adjustment, and have structure simple, be easy to the advantages such as operation and maintenance.
Description
Technical field
The utility model relates to permanent magnetic speed-adjusting technical field, particularly relates to a kind of permanent magnetic speed-adjusting mechanism.
Background technology
In the production process in multiple fields such as mining, papermaking, cement, petrochemical industry, metallurgy, widely apply the speed control devices such as reductor, variable-frequency governor, fluid coupling, easy to operate.But the not necessarily energy-conserving and environment-protective of these speed regulating device, and have complex structure, maintainable poor, the shortcomings such as adaptive capacity to environment difference.In recent years, permanent magnetic speed-adjusting becomes study hotspot, and has the advantages such as good environmental suitability and energy-conserving and environment-protective because of it and be applied to different industrial circles.At present, typical permanent-magnet speed governor is divided into disc type and cartridge type two kinds.Between the magnetic conductor of desk permanent-magnet speed regulator and permanent magnet, interval is little, and heat dispersion is not good, requires high to permanent magnet.Cartridge type permanent-magnet speed governor speed adjustable range is large, it is little to take radial space, but axial mounting distance is large, and axle alignment precision requires high.
Application number be 201220220474.3 patent provide a kind of permanent-magnet speed governor being reached speed governing object by the coupling distance between radiai adjustment magnetic conductor and permanent magnet.But this cartridge type permanent-magnet speed governor, without the need to moving axially, substantially reduces axial mounting distance, improve adjusting speed accuracy and operability.But, the permanent-magnet speed governor governor motion involved by this patent is complicated, and maintenance difficulties is large, and it is many to be disturbed factor.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of by moving radially that mode regulates coupled relation between permanent magnet and magnetic conductor and structure is simple, the class cartridge type permanent magnetic speed-adjusting mechanism that is easy to operation and maintenance.
In order to realize above object, the utility model adopts following technical scheme.
A kind of permanent magnetic speed-adjusting mechanism, comprise power shaft, output shaft, magnetic conductive disk, the round shape fixed disk be fixedly linked on output shaft, move radially with round shape fixed disk the permanent magnet that support, annulus plate-like permanent magnet fixed disk and symmetry that duplicate invoice connects are fixedly installed in annulus plate-like permanent magnet fixed disk both sides, it is characterized in that: described magnetic conductive disk is that odd number to be evenly fixedly installed on power shaft and coaxial with power shaft at equal intervals; Described annulus plate-like permanent magnet fixed disk is made up of the fan-shaped fixed head that 6 are spacedly distributed; Described annulus plate-like permanent magnet fixed disk is placed in the middle of the interval that formed by two adjacent magnetic conductive disks; Described fan-shaped fixed head is fixedly mounted on support.

The utility model has the following advantages and beneficial effect.
The utility model achieves the radiai adjustment of coupled relation between permanent magnet and magnetic conductor, without the need to axial adjustment, and has compact conformation, is easy to the advantages such as operation and maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of permanent magnetic speed-adjusting mechanism.
Fig. 2 is the structural representation of annulus plate-like permanent magnet fixed disk.
Fig. 3 is the schematic three dimensional views of the assembly be installed on output shaft.
In figure: 1 is power shaft, 2 is output shafts, and 3 is magnetic conductive disks, and 4 is supports, and 5 is round shape fixed disks, and 6 is annulus plate-like permanent magnet fixed disks, and 7 is permanent magnets, and 8 is fan-shaped fixed heads.
Embodiment
Below in conjunction with accompanying drawing, execution mode of the present utility model is described in detail.
A kind of permanent magnetic speed-adjusting mechanism that the utility model provides, comprises power shaft 1, output shaft 2, magnetic conductive disk 3, the round shape fixed disk 5 be fixedly linked on output shaft 2, moves radially with round shape fixed disk 5 permanent magnet 7 that support 4, annulus plate-like permanent magnet fixed disk 6 and symmetry that duplicate invoice connects are fixedly installed in annulus plate-like permanent magnet fixed disk 6 both sides.Wherein, magnetic conductive disk 3 totally 3.
3 magnetic conductive disks 3 to be evenly fixedly installed on power shaft 1 and all coaxial with power shaft 1 at equal intervals.The fan-shaped fixed head 8 that 2 annulus plate-like permanent magnet fixed disk 6 each freedom 6 are spacedly distributed forms, and is placed in respectively in the middle of interval that magnetic conductive disk 3 formed.Fan-shaped fixed head 8 is fixedly mounted on support 4.The material of magnetic conductive disk 3 is brass HT62.The magnetic polarity of the adjacent permanent magnet 7 of the same side of annulus plate-like permanent magnet fixed disk 6 is contrary.
The operation principle of said mechanism is: when the support 4 that moving sets is connected in round shape fixed disk 5 radially moves to the axis of output shaft 2, drive the fan-shaped fixed head 8 that is fixedly connected with it and on permanent magnet 7 move thereupon, now, permanent magnet 7 slowly enters in the interval of magnetic conductive disk 3, therefore coupling area between permanent magnet 7 and magnetic conductive disk 3 also increases gradually, like this, output shaft 2 obtain rotating speed and power constantly raise.Otherwise the coupling area between permanent magnet 7 and magnetic conductive disk 3 constantly reduces, the rotating speed that output shaft 2 obtains and power then decrease.The adjustment of mode like this by constantly regulating the coupling area between permanent magnet 7 and magnetic conductive disk 3 to realize output shaft rotating speed and power output.
