Abstract
本发明涉及机械传动联轴器，更具体说是一种非接触式过载保护磁力传动联轴器。通过在主、被动联轴器的两个连接盘上均匀地安装高磁通磁铁，使相邻两块磁铁的N、S级相反。两个联轴器安装时在两个盘间留出1mm左右的间隙。主动盘旋转使，通过磁力带动被动盘旋转。工作时，对两个轴的同轴度要求降低。本发明可以有效解决普通联轴器工作时存在接触，摩擦磨损，噪音大等不足，采用非接触型式，提高系统的安全性和可靠性。本发明结构简单，不需要对现有产品进行大的改动，成本低，安装方便。
The invention relates to a mechanical transmission coupling, more specifically a non-contact overload protection magnetic transmission coupling. By evenly installing high-flux magnets on the two connection plates of the main and passive couplings, the N and S levels of the adjacent two magnets are reversed. Leave a gap of about 1 mm between the two discs when the two couplings are installed. The rotation of the active disk drives the passive disk to rotate through magnetic force. When working, the requirements for the coaxiality of the two shafts are reduced. The invention can effectively solve the problems of contact, friction and wear, high noise and the like when the common shaft coupling works, and adopts a non-contact type to improve the safety and reliability of the system. The invention has the advantages of simple structure, no need of major modification to existing products, low cost and convenient installation.
Description
Technical field
The present invention relates to the machine driving shaft coupling, a kind of contactless overload protection Magnetic Force Transmission Coupling of more specifically saying so.
Background technology
Shaft coupling is that two axles (driving shaft and driven shaft) that are used for connecting in the different institutions make it the machine components of common rotation with transfer torque.In the power transmission of high-speed overload, it is the effect of dynamic property that shaft coupling must possess buffering, vibration damping, safeguard protection and raising axle.Shaft coupling is made up of two halves, connects with driving shaft and driven shaft respectively.General engine mostly links by means of shaft coupling and working machine.Machenical coupling, in industry extensive application such as engineering machinery, agricultural machinery, lathe, molding machine, metallurgy, mine, petrochemical industry, railway, boats and ships, light industry and machinery, tracked armored vehicles, its fail safe is very important.
The metallic elastic component spring coupling that uses mainly comprises: ( 1 ) GB/T 12922-1991 elastic damping flat spring coupling ( 2 ) GB/T14653-1993 flexibility bar shaft coupling ( 3 ) JB/T 9147-1999 diaphragm coupling ( replacing ZB/T J19022-90 ) ( 4 ) JB/T 8869-2000 Falk flexible coupling ( replacing ZB/T J19023-90 ) at present.,： ( 1 ) BG/T 2496-1996 ( GB 2496-81 ) ( 2 ) BG/T 4323-1984 ( 3 ) BG/T 5014-1985 ( 4 ) BG/T 5015-1985 ( 5 ) BG/T 5272-1985 ( 6 ) BG/T5844-1986 ( 7 ) BG/T 10614-1989 ( 8 ) JB/T 5511-1991H ( 9 ) JB/T 5512-1991 ( 10 ) JB/T 7849-1995 ( 11 ) JB/T 7684-1955LAK ( 12 ) JB/T 9148-1999 ( ZBJ 19029-90 )
There is contact during these shaft coupling work, fretting wear, the big deficiency that waits of noise.When the overload accident in use took place, fracturing member easily flew out and hurts sb.'s feelings, and ruins thing, and is very dangerous.
Summary of the invention
Purpose of the present invention is existence contact when effectively the common shaft coupling of solution is worked just, fretting wear, the big deficiency that waits of noise, employing noncontact pattern, the fail safe and the reliability of raising system.The present invention is simple in structure, does not need existing product is carried out big change, and cost is low, and is easy for installation.
The technical scheme that technical solution problem of the present invention is adopted is:
By leading, high magnetic flux magnet being installed equably on two terminal pads of passive shaft coupling, make the N of adjacent two blocks of magnet, S level opposite.When installing, two shaft couplings between two dishes, reserve the gap about 1mm.The driving disc spacing pressing rotation makes, and drives the driven disc rotation by magnetic force.During work, to the axiality requirement reduction of two axles.
