Problems solved by technology

However, there are the following defects: the system overload coefficient cannot be selected too large, otherwise the system will start too short, lose the soft start effect, cause a large impact on the power grid when starting, and even burn out the motor or damage the weak zero of the working machine. part

Embodiment Construction

[0015] Now according to figure 1 The shown feedback control friction coupling principle further illustrates the solution of the present invention.

[0016] Such as figure 1 As shown, the feedback control friction coupler is composed of a driving device and a driven device; the driving device is composed of the driving shaft 1 connected with the driving core 6 installed in the coupler housing 9 through a coupling; the driven device is A device that connects the coupling housing 9 to the drive shaft 1 via bearings 10 .

[0017] During implementation, the core disc circumference part of active movement 6 is processed into left flange 4 and right flange 7 extending to both sides respectively, and the inner surface of flange 4 and 7 is used as driven friction surface; The driven cores 2 and 8 with the same structure as the active core 6 are respectively arranged on the side, and the driven cores 2 and 8 are respectively connected with the coupler housing 9 to rotate together, and...

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 ofthe 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 anddriven 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 [0001] The present invention relates to soft starting systems, and more particularly to friction couplings. Background technique [0002] In recent years, friction principle couplers have been used in soft start systems. It consists of a driving device and a driven device. The driving device is connected by the driving shaft through an appropriate coupling and the driving movement. The force transmission groove, each force transmission groove is equipped with a return spring, an inertia block and a friction block. The driven device is an output member composed of a coupler housing. The inner surface of the coupler housing forms a circle of active friction surfaces. The friction surface cooperates with the friction block. The working principle is: when the driving shaft rotates, the driving movement rotates rapidly together to generate centrifugal force, and the inertia block moves outward to make the friction block gradually tighten on the active friction s...
