Abstract
The utility model relates to a novel magnetic particle clutch stepless speed regulation motor. The novel magnetic particle clutch stepless speed regulation motor uses an asynchronous motor which has no function of speed regulation intrinsically as the prime motor, and realizes the speed regulation through changing the exciting current of the magnetic particle clutch. The utility model has the advantages of great speed regulation range, low exciting voltage, safety, reliability, great locked-rotor torque, rapidity of the response, small volume, low fabrication cost, long service life etc.
Description
One, technical field:
The utility model relates to a kind of novel magnetic powder cluth stepless speed-regulating motor.
Two, background technology:
Buncher is that all trades and professions are used very wide a kind of equipment.The speed regulating method that has better speed governing flatness at present mainly contains: frequency control, electromagnetic slip clutch speed governing, tandem control etc.Wherein, the electromagnetic slip clutch speed governing is comparatively extensive, mainly is because this method can realize smooth stepless speed-regulating, plays clutch action and can realize overload protection.But the mechanical property of electromagnetic clutch governing system under the different exciting electric current is very soft, and exciting current is more little, and characteristic is soft more, and the stall poor performance is replied slowly.Such mechanical property can not be applied in and require on the more stable work mechanism of speed.And the maximum of electromagnetic clutch transmission efficiency is 80%～90%, and promptly the electromagnetic slip clutch peak power output is about about 80%～90% of driving motor power.Along with the reduction of output speed, the also corresponding reduction of transmission efficiency is so this governing system is unsuitable for being in over a long time the manufacturing machine of low speed.In addition, there is uncontrollable district in this governing system, and is because the friction and the existence of remanent magnetism, when load torque during less than 10% nominal torque, possible out of control.For example, the 1.1kw buncher cuts off exciting current, and minimum speed has 125r/min.Simultaneously, the size of this buncher is bigger, and is generally big by 1/3 than common electric machine.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of novel magnetic powder cluth stepless speed-regulating motor of realizing speed governing by the exciting current that changes magnetic powder cluth.
The technical solution of the utility model is: a kind of novel magnetic powder cluth stepless speed-regulating motor, constitute by motor and magnetic powder cluth, and it is characterized in that: rotor axis of electric is connected with the driving link of magnetic powder cluth, and the driven member of magnetic powder cluth is connected with output shaft; Described magnetic powder cluth is that driven member, magnetic, magnet exciting coil, electromagnetic rotor are that driving link and conducting ring constitute by metal outer cylinder mainly, at metal outer cylinder is that driven member and electromagnetic rotor are to leave the gap between the driving link, magnetic is arranged in the gap, and it is in the driving link that magnet exciting coil is arranged on electromagnetic rotor.
Gap between principal and subordinate's moving part of magnetic powder cluth of the present utility model is 1.5～2mm.
The utility model is when in the magnet exciting coil during no current, and powder does not hinder the relative motion between principal and subordinate's moving part like the loose sand, and clutch is in released state, when feeding electric current, electromagnetic powder promptly is attracted magnetization under the action of a magnetic field assembles, and mixes crack magnetic circuit formation chain solid, by its adhesion, principal and subordinate's moving part is connected, clutch is combination, and this combination is linear with exciting current, thereby realizes transmission of torque, and can realize deciding torque output, reach the purpose of speed governing.Because the variation and the exciting current of magnetic powder cluth torque are linear substantially, so just can reply in time, and can show good repeatability by regulating the exciting current size of controlling torque exactly.Therefore, the magnetic powder cluth buncher has speed adjustable range big, and exciting voltage is low, and is safe and reliable, and locked-rotor torque is big, replys rapidly, and volume is little, and is in light weight, low cost, advantages such as life-span length.
Four, description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the magnetic powder cluth structural representation.
Among the figure: 1, motor; 2, driving link; 3, magnetic powder cluth; 4, magnet exciting coil input pin; 5, magnet exciting coil; 6, driven member; 7, output shaft; 8, magnetic.
Five, embodiment
As shown in Figure 1, the utility model is by motor 1, driving link 2, magnetic powder cluth 3, magnet exciting coil input pin 4; Magnet exciting coil 5; Driven member 6; Output shaft 7; Magnetic 8 constitutes.Motor is that asynchronous motor is prime mover, realizes speed governing by the exciting current that changes magnetic powder cluth.Rotor axis of electric is connected with the driving link of magnetic powder cluth, and the driven member of magnetic powder cluth is connected with output shaft.
As shown in Figure 2, magnetic powder cluth of the present utility model is that driven member 6, magnetic 8, magnet exciting coil 5, electromagnetic rotor are that driving link 2 constitutes by metal outer cylinder, leave 1.5～2mm gap between its driving link and the driven member, magnetic just is contained in the gap between driving link and the driven member.When in the magnet exciting coil during no current, small antiwear spherical magnetic does not hinder the relative motion between the driven member like the loose sand, and clutch is in released state, and when feeding electric current, the magnetic gathering that is magnetized connects principal and subordinate's moving part the clutch combination.
