Description

A kind of flexible coupling of the nonmetal elastic element of employing of transmitting large torque

Technical field

The utility model relates to a kind of flexible coupling, especially relates to a kind of flexible coupling of the nonmetal elastic element of employing of transmitting large torque.

Background technique

Existing coupling kind specification is a lot, as Chinese patent CN201636232U, announced a kind of coupling, a kind of mechanical transmission connection set specifically, by two, form with the identical half-coupling of the shape of pawl pin and an elastic element, two half-couplings are by the end docking engaging with the pawl pin, elastic element is placed between two half-couplings, it is characterized in that: half-coupling is comprised of axle sleeve, bolt cover and end cap three parts, the axle sleeve outside is connected with bolt cover is inboard, and the bolt cover lower end is fixed with the separated type end cap.This separated type end cap can disassemble from bolt cover easily, reaches the purpose that is convenient for changing the elastic element between half-coupling, has greatly shortened the replacing time, and has saved human and material resources.Chinese patent CN2643068U discloses a kind of retrial elastic coupling flexible coupling, the spacer flanger that comprises two shaft couplings, two shaft couplings of connection, one of them has pooling feature, the spring pin assembly of take is elastic element, the elastic coupling of free-extension vertically, another is not have pooling feature, take the flexible coupling of man type diaphragm unit as flexible element.

But above-mentioned coupling can not meet work long hours violent in vibrations, dust is serious, under the unsettled working condition of load, and above-mentioned coupling does not have the requirement of high rotating speed and high pass moment of torsion.Therefore, the utility model provide a kind of can adapt to high rotating speed and high pass moment of torsion, can work long hours violent in vibrations, dust is serious, the flexible coupling under the unsettled working condition of load.

The model utility content

The purpose of this utility model is exactly that a kind of simple in structure, installation and maintenance flexible coupling of the nonmetal elastic element of employing of transmitting large torque easily is provided in order to overcome the defect that above-mentioned prior art exists.

The purpose of this utility model can be achieved through the following technical solutions:

A kind of flexible coupling of the nonmetal elastic element of employing of transmitting large torque, comprise the lower half-coupling be connected with the output shaft of gear reducer, and the upper half-coupling be connected with the spiral stirring shaft, described upper half-coupling and lower half-coupling are bolted, the inboard of described upper half-coupling is provided with at least one elastic element, and this elastic element is the block rubber of ring.

Described elastic element is provided with 3.

The end of described upper half-coupling and lower half-coupling is provided with end cap.

Between described end cap and upper half-coupling or lower half-coupling, be bolted fixing.

Described upper half-coupling and lower half-coupling are formed by cast steel or weldment manufacture.Upper half-coupling or lower half-coupling and the contacted working surface of elastic element are processed processing.

Described elastic element adopts the die casting moulding, guarantees that size is basically identical.

When the output shaft of gear reducer rotates, the upper half-coupling of lower half-coupling drive is done synchronously, rotating Vortex, with the spiral stirring shaft that upper half-coupling connects, do together synchronize, rotating Vortex, the elastic element be distributed in half-coupling plays compensating action, realizes the flexible connection of transmitting large torque.

Compared with prior art, the utlity model has following advantage:

(1) Dimensions, transmitting torque and working condition all can meet the demands;

(2) elastic element adopts the die casting moulding, and size is basically identical, and anufacturability is good, and manufacture cost is lower;

(3) simple in structure, compact, installation and maintenance are convenient;

(4) coupling of the present utility model can be worked under the rotating speed of 30 rev/mins, and transmitting torque is 559209 Ns of rice, and size is large;

(5) coupling of the present utility model can be operated in that vibrations are violent, dust is serious, under the unsettled working condition of load.
