Background technology
Shaft coupling is used to connect two axle driving shafts in different institutions and driven shaft, thus makes it jointly to rotate with the machine components of transmitting torque, and shaft coupling is for playing the effect of transmitting torque.
The two halves of traditional shaft coupling directly contacts connection usually, such as, be connected with a joggle by gear structure, to realize the transmission of moment of torsion.But in the process of transmitting torque, this contact connected mode between the two halves of shaft coupling can produce larger friction and collision, there is no padded coaming between the shaft coupling of simultaneously all-metal construction, can not realize flexibly connecting; When motor is not enough to drive working machine running, easily causes the damage of self and motor, usually also can produce larger noise when rubbing.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, provide a kind of flexible magnetic suction burn-out-proof shaft coupling, it is rational in infrastructure, have easy to use, not fragile, noise is little and can prevent the advantage of burn-down of electric motor, flexible startup effectively solves shaft coupling and to be rigidly connected the burn-down of electric motor caused.
The utility model solves the technical scheme that its technical problem adopts: a kind of flexible magnetic suction burn-out-proof shaft coupling, comprises upper end, elastomer, magnetic connecting portion, separator, bottom and shell; Described upper end comprises locating ring, be arranged on the first sector of locating ring lower end and be arranged on the Upper shaft sleeve of locating ring upper end; Described Upper shaft sleeve is provided with fastening screw; Described Upper shaft sleeve inside is conical cavity structure; Described Upper shaft sleeve inwall is provided with keyway and some anti-skidding stripeds;
Described magnetic connecting portion comprises the second sector being arranged on top and the first magnet being arranged on the second sector bottom; Described bottom comprises the second magnet and Lower shaft sleeve; The first described magnet and the second magnet mutually adsorb to be connected;
Described elastomer is arranged between the first sector and the second sector; Described elastomer is hub-and-spoke configuration; Described separator is arranged on the smooth circular plate structure between the first described magnet and the second magnet; Described shell is the hollow circular cylinder be arranged between Upper shaft sleeve and Lower shaft sleeve; The first described sector and the second sector are connected with a joggle by the mutual clamping of elastomer.
As preferred scheme, described elastomer is that interference fits is connected with the first described sector and the second sector.
As preferred scheme, described separator is that flexible material is made.
The beneficial effects of the utility model are: provide a kind of flexible magnetic suction burn-out-proof shaft coupling, it adopts three stage structure, one end adopts the mode of two magnetic pole absorption to connect, magnetic force between two magnetic poles is slightly less than the maximum outputting power of motor, when motor is not enough to drive working machine running, motor power is greater than magnetic force, and driving shaft can be rotated further the effect reaching burn-out-proof; The other end adopts sector to be connected with a joggle, and simultaneously between sector, embeds elastomer, prevent mechanically activated or stop time junction to collide the generation of wearing and tearing and noise.It is rational in infrastructure, have easy to use, not fragile, noise is little and can prevent the advantage of burn-down of electric motor, flexible startup effectively solves shaft coupling and to be rigidly connected the burn-down of electric motor caused.
