Abstract
The invention discloses a method for implementing feedback moment of a friction coupler. The method comprises the following steps: firstly, machining the circumference part of a driving movement disc of the friction coupler to form a flange extending to two sides, wherein the inner face of the flange is used as a driven friction surface; and then, arranging driven movements with the same structures as a driving movement on the two sides of the driving movement, wherein the two driven movements are connected with a shell of the coupler together to rotate respectively, driven friction blocks of the driven movements are matched with the inner face of the flange of the driving movement, and the driven friction blocks are propped against the inner face of the flange of the driving movement when the driven movements rotate so as to generate feedback friction driving moment. The method of the invention changes the current situation that the conventional coupler transfers the load only by means of active inertia force rubbing effect so as to prolong the starting time and have good soft starting effect; and the comprehensive overload factor is large, the slip difference between driving and driven devices is eliminated, the efficiency is improved, sliding friction is avoided and heat generated by power is consumed, so that the over-high temperature rise of the system is avoided.
Description
Technical field
The present invention relates to the soft start system, relate in particular to friction coupler.
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 through suitable coupling and the movement initiatively knot that links by driving shaft; Initiatively movement is not both the individual radially power transmission groove at movement dish circumference uniform distribution 3-6 by type, in each power transmission groove Returnning spring, inertial mass and brake pad is housed, and driven device is an output link that is made up of the Coupler housing; The internal surface of Coupler housing forms initiatively rubbing surface of a circle, and initiatively rubbing surface matches with brake pad.Working principle is: when driving shaft rotated, the active movement is quick rotation together, produces centrifugal force; Inertial mass is moved outward brake pad is held out against gradually on the active rubbing surface of driven device; Thereby produce friction driving moment, drive the driven device rotation, realize power transmission.This kind of drive shows certain superiority, as: rate of fault is low, easy to maintenance, the life-span is long etc.But have following defective: 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.As far as 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 problem that always need solve in the industry.
Summary of the invention
The present invention is in order to overcome the above-mentioned deficiency of existing technology, the implementation method of inventing a kind of feedback moment of friction coupler.
The technical solution adopted for the present invention to solve the technical problems is:
At first the circumferential section with the active movement dish of friction type Coupler is processed into the flange that extends to both sides, and the inner face of flange is as driven rubbing surface; The driven movement identical with the mover core construct is set respectively in active movement both sides then; Two driven movements respectively with the rotation that links together of Coupler housing; The driven brake pad of driven movement matches with the inner face of active movement flange; When driven movement rotates, thereby driven brake pad withstands on the inner face of movement flange initiatively and produces feedback friction driving moment.
In order to strengthen the feedback friction area, the inclined-plane that the driven rubbing surface of active movement and the driven brake pad of driven movement are designed to match.
The principle of above-mentioned feedback is:
System's starting initial stage; Driving shaft drives active movement quick rotation together, produces centrifugal force, and initiatively inertial mass is moved outward the active brake pad is withstood on the active rubbing surface of Coupler housing gradually; Thereby produce initial stage friction driving moment, drive driven device and rotate from slow to fast.After the driven device rotating speed reached certain value, the centrifugal force of driven movement made inertial mass begin outer moving, and promoted on the driven rubbing surface that driven brake pad withstands on movement initiatively gradually; Thereby produce later stage feedback friction driving moment; After original friction driving moment stack, further drive driven device and rotate, driving and driven device rotates synchronously when reaching the setting rotating speed; Eliminate slippage, realize the full power transmission.
Advantage of the present invention is:
1, use this method after, changed existing Coupler and only leaned on the initiatively present situation of level inertial force rubbing action transmitted load, the starting time is prolonged, soft start is effective;
2, comprehensive overloading ratio is big, has eliminated the slippage between driving and driven device, has improved efficient, the heat of avoiding the sliding friction consumed power to produce, thus avoid system's temperature rise too high.
In a word, use this method design friction coupler, can make more superior, the more compact structure of soft start systematic function.
