The feedback control friction coupler disclosed in the utility model is characterized in that inner conical friction surfaces are arranged on peripheries of the left and right sides of the active core disc of the active device; room, where passive cores connected with the passive device are installed, is reserved respectively between the left and right sides of the active core and the passive device; the passive core has the same structure with the active core; three to six radial force transmission grooves are evenly distributed on the passive core disc, with each groove having a return spring, an inertia block and a friction pad; and an outer conical friction surface is arranged on the friction pads to match with the inner conical friction surfaces of the active core disc. The utility model provides a relatively longer and reasonable period of time for a soft startup when the soft startup system is under a relatively high overload condition.
Description
Technical field
The utility model relates to the friction coupler of a kind of soft start system.
Background technique
The Coupler of tribology principle is brought into use in the soft start system in recent years.It is made up of aggressive device and driven device, aggressive device is to be connect mutually with the active movement by suitable coupling by driving shaft, initiatively movement is the individual radially power transmission groove of uniform 3-6 on active movement disk, in each power transmission groove Returnning spring, inertial mass and brake pad is housed; Driven device is the output link of a band housing; Inertial force that inertial mass produced when aggressive device rotated and brake pad driving moment drive output link and rotate, and carry out power transmission.It has certain superiority, as: rate of fault is low, easy to maintenance, the life-span is long etc.; But also there is following defective: only drive the inertial mass aggressive device and produce inertial force and brake pad driving moment, can not realize that driving inertial mass with driven device produces inertial force and frictional force and drive aggressive device by movement initiatively.This defective causes: it is bigger that the system overload coefficient can not be got, otherwise will make system's starting time too short, loses the soft start effect, during starting electrical network caused big impact, even can burn out the weak component of motor or damage work mechanism.For friction coupling soft start system, how to be implemented under the suitably big comprehensive overloading ratio prerequisite, there is long reasonable soft starting time in system, is the industrial problem that solves of always needing.
The model utility content
The utility model proposes a kind of feedback control friction coupler for realizing that under suitably big comprehensive overloading ratio prerequisite, there is long reasonable soft starting time problem in the soft start system.
A kind of feedback control friction coupler, main structure is: it comprises existing aggressive device and driven device, it is characterized in that, the periphery of the active movement disk left and right side of aggressive device is equipped with the inner conical rubbing surface; Initiatively be respectively equipped with the space between the and arranged on left and right sides of movement and the driven device, be respectively equipped with the driven movement that is connected with driven device in the space; The structure of driven movement is with initiatively movement is identical, it is the individual radially power transmission groove of uniform 3-6 on driven movement disk, in each power transmission groove Returnning spring, inertial mass and brake pad are housed, wherein brake pad is provided with the external conical shape rubbing surface that matches with the inner conical rubbing surface of active movement disk.
The working principle of above-mentioned feedback control friction coupler is: the starting initial stage, the driving shaft of aggressive device drives initiatively, and movement rotates, the inertial mass of active movement produces radially, and inertial centrifugal force outwards moves, produce friction driving moment behind the housing of brake pad contact driven device, the output link that drives driven device slowly starts; After the output link rotating speed reaches certain value, driven movement inertial mass produces radially inertial centrifugal force again and overcomes elastic force and moves outward, also produce friction driving moment behind the inner conical rubbing surface of driven movement brake pad contact active movement, the output link that further drives driven device rotates, and comprehensive overloading ratio is further increased because of superposeing.Reach when setting rotating speed, the moving device of principal and subordinate rotates synchronously, eliminates slippage, avoids the sliding friction consumed power to produce heat, thereby avoids system's temperature rise too high.
In a word, feedback control friction coupling principle is exactly that driven device with Coupler drives driven movement inertia friction piece rotation, thereby the generation inertial centrifugal force makes the inner conical rubbing surface on the driven movement brake pad extruding active movement, further drives driven device by friction torque and rotates.
The utility model has the advantages that:
1, adopt " feedback control friction coupling " principle, the overloading ratio when having reduced starting has prolonged the starting time, has improved the soft start effect; Increase the comprehensive overloading ratio when running well, eliminated the slippage between the moving device of principal and subordinate, improved efficient, reduced the temperature rise of system.
2, in friction coupling soft start system, use feedback control friction coupling principle, changed that existing Coupler is only little by level inertial force friction gearing transmitted load initiatively, comprehensive overloading ratio, the present situation of soft start weak effect.
In a word, the utility model has overcome with the Coupler starting time weak point that has the friction coupling principle now, can not get than shortcomings such as big comprehensive overloading ratios, uses this model utility, can make more superior, the more compact structure of friction coupling soft start systematic function.
