Abstract
The utility model discloses a detachable elastic coupler. The coupler comprises left and right half coupler components and an elastic element. The elastic element is disposed in the middle of the left and right half coupler components. Each of the left and right half coupler components comprises a half coupler, a plurality of claw blocks and connection bolts. The claw blocks are connected with the inner sides of flange faces of the half couplers, and the elastic element is clamped between the claw blocks. By means of the coupler, when the normal operation of the coupler is affected due to serious damage or abrasions to the elastic element, the elastic element can be detached through the connection bolts independently to be changed; by introducing the claw blocks, the blank material consumption is low, and compared with traditional integral half couplers, the coupler has the advantages that the forge piece blank material usage rate is greatly improved, and the machining cost is saved.
Description
Technical field
The utility model relates to coupling technical field, relates in particular to a kind of nonmetal elastic coupling flexible coupling.
Background technique
Coupling belongs to mechanical transmission coupling, be motion for prime mover is produced and transmission of torque to the device of driven machine, have between compensation prime mover and driven machine because the impact of foozle, alignment error, load metamorphism and temperature variation etc. is caused axially, the function of angle and radial deflection simultaneously.
Traditional nonmetal elastic coupling flexible coupling, for example Quincunx elastic coupler and star-shaped elastic coupling, to utilize elastic element to be placed between the two half-coupling dogs of left and right to realize the connection of two half-couplings, in a lot of situations, left and right two half-couplings are interference fit joint with connecting of two ends shaft extension, when elastomer damage or serious wear, be inconvenient to carry out dismounting and change; Meanwhile, when half-coupling adopts forging blank, because its claw type groove is difficult for directly forging, so its stock utilization is lower, also makes processing cost increase.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of elastic coupling flexible coupling, when elastomer damage or serious wear, can carry out dismounting and change individually to it.Meanwhile, this coupler structure is simple, processing cost is lower.
A kind of detachable elastic coupling flexible coupling of the utility model, it comprises left and right half-coupling assembly and elastomer, the centre of elastomer in left and right half-coupling assembly; Left and right half-coupling assembly includes half-coupling, several claw type pieces, attachment bolt, and claw type piece is connected in the inner side of half-coupling flanged surface by attachment bolt, and elastomer is stuck between claw type piece.
This left and right half-coupling assembly in novel is dismountable split-type structural, like this, and when elastomer damages or when serious wear has influence on the normal operation of coupling, can elastomer be unloaded separately and be changed by attachment bolt.This New Model of Flexible Coupling, by introducing claw type piece, consumes blank material low, compares with traditional integrated type half-coupling, has greatly improved the utilization ratio of forging blank material, and then has also saved processing cost.
Elastic coupling flexible coupling of the present utility model is simple in structure, easy to maintenance, and cost of material and processing cost are lower, good economy performance, and work is comparatively reliable, is specially adapted to the transmission joint occasion of middle light duty.
Accompanying drawing explanation

Fig. 2 is the exploded view of elastic coupling flexible coupling of the present utility model;
Fig. 3 is claw type block structure schematic diagram of the present utility model.
Embodiment
From Fig. 1, Fig. 2, Fig. 3, a kind of detachable elastic coupling flexible coupling of the utility model, it comprises left and right half-coupling assembly and elastomer 3, the centre of elastomer 3 in left and right half-coupling assembly; Left and right half-coupling assembly includes half-coupling 1, several claw type pieces 2, attachment bolt 4, and claw type piece 2 is connected in the inner side of half-coupling 1 flanged surface by attachment bolt 4, and elastomer 3 is stuck between claw type piece 2.During coupling running, by the extruding transmitting torque between claw type piece 2 and elastomer 3, by the resiliently deformable of elastomer 3, compensate the relativity shift of join diaxon.
For using bolt 4 to be connected into an integral body half-coupling 1 and claw type piece 2, on half-coupling 1 flanged surface, have bolt hole 11, on claw type piece 2, corresponding position has tapped hole 21, and attachment bolt 4 is connected both.Attachment bolt 4 stretches into the bolt hole 11 on half-coupling 1 flange, and screws in the tapped hole 21 on claw type piece 2, thereby makes half-coupling 1 and claw type piece 2 be connected into an integral body.In the time will changing elastomer 3, only need unclamp bolt 4, can claw type piece 2 is separated with half-coupling 1, take off the elastomer 3 of damage, change new elastomer 3, then by half-coupling 1 and 2 use bolt 4 assemblings of claw type piece.
Wherein, elastomer 3 is non-metal component, and its shape can be quincunx, star, and its lobe number is even number; The face that claw type piece 2 contacts with elastomer 3 is groove 22, and corresponding with the shape of elastomer 3, both fit tightly.Elastomer 3 can be selected wear-resisting, anti-oil, aging-resistant high-strength polyurethane material, and the lobe of elastomer 3 embeds in groove 22.When coupling is worked, the cylinder shape groove 22 of the lobe of elastomer 3 and claw type piece 2 pushes mutually, to realize the transmission of moment of torsion.
This New Model of Flexible Coupling is in the process of transmitting torque, and attachment bolt 4 becomes the strength member of transmitting torque, therefore in the higher occasion of working condition requirement, and the reliability connecting for further improving bolt 4, attachment bolt 4 is high-strength bolt.
This New Model of Flexible Coupling, by introducing claw type piece, consumes blank material low, compares with traditional integrated type half-coupling, has greatly improved the utilization ratio of forging blank material, and then has also saved processing cost.
Elastic coupling flexible coupling of the present utility model is simple in structure, easy to maintenance, and cost of material and processing cost are lower, good economy performance, and work is comparatively reliable, is specially adapted to the transmission joint occasion of middle light duty.
