Abstract

The utility model relates to an elastic coupling, which belongs to the field of vehicle transmission fittings. The utility model is composed of a wheel hub, a rubber ring and a coupling disk. The rubber ring and the coupling disk are bonded into a whole, and the rubber ring is inlaid in a groove of the wheel hub. When the utility model is in use, the wheel hub is connected with an engine flywheel, the coupling disk is connected with an output shaft to transfer power, and the rubber ring plays a role of damping the shock. The utility model has the characteristics of high strength and good shock damping property. The utility model is suitable for use in oversize vehicles.

Description

Elastic coupling flexible coupling

The utility model relates to a kind of elastic coupling flexible coupling, belongs to system of vehicle transmission accessory field.

At present, truck conspicuity marking such as quarry tipper, control pick machine, stone crusher etc. use in a large number, the impulsive load of this vehicle is big, and need Fraquent start, make transmission shaft bear huge vibrations and moment of torsion, thereby a kind of bearing capacity of transmission shaft needs is strong, the coupling that shock-absorbing capacity is good, but existing coupling is not really desirable.

The purpose of this utility model is exactly to provide a kind of elastic coupling flexible coupling with high loading and buffering ability for large vehicle.

Above-mentioned purpose of the present utility model is achieved in that by wheel hub, rubber ring and land forms coupling, wherein outmost metal wheel hub connects with the flywheel of internal-combustion engine, the interior ring of wheel hub has a groove, rubber ring and metal land are one through the vulcanizing treatment posterior synechia, rubber ring embeds in the groove of wheel hub, and land connects with output shaft, forms an elastic coupling flexible coupling like this.

Description of drawings:

Fig. 1 is overall structure figure of the present utility model;

Fig. 2 is a side of the present utility model part sectioned view.

Below in conjunction with accompanying drawing the technical solution of the utility model is described further;

Accompanying drawing provides a kind of embodiment of the present utility model, it is by wheel hub [1], rubber ring [2], land [3] is formed, its structural characteristics are: the inner ring surface of wheel hub [1] is a groove, the left side of groove, right two convex edges are one high and one low not contour, rubber ring [2] then is one of the cross section elastic caoutchouc that is isosceles trapezoid, its characteristic is that elastic force is good, and have oil resistant and be difficult for aging characteristics, the outer surface of the bottom surface of rubber ring [2] and land [3] is bonded as one through after the vulcanizing treatment, the cross-sectional dimension of rubber ring [2] is greater than the inner ring surface groove size of wheel hub [1] simultaneously, rubber ring [2] is embedded into the wheel hub [1] with enough magnitude of interference from the low convex edge of the groove of wheel hub [1], magnitude of interference should suitably be adjusted according to different coupling sizes, embed with rubber ring that wheel hub is non-slip to be as the criterion, this interference fit will make between wheel hub [1] and the rubber ring [2], the dependence elasticity tension closely cooperates, produce enough frictional force, come transmitting torque, and can bear huge moment moment of torsion in when starting, rubber ring [2] and land [3] one body actions, outputting power.

The beneficial effects of the utility model are:

1. it has the intensity height, the advantage that bearing capacity is big, and maximum load or moment of torsion rushes in the time of can bearing starting Hit.

2. its good springiness, damping is big, has enough mitigation impact and cushioning ability.

3. its is simple in structure, easy accessibility.

Claims

A kind of elastic coupling flexible coupling, form by wheel hub, rubber ring, land, it is characterized in that the wheel hub inner ring surface is a groove, its left and right two convex edges are one high and one low not contour, rubber ring then is an elastic caoutchouc spare that cross section is an isosceles trapezoid, the sulfuration of the outer surface of its bottom surface and land is bonded as one, and the cross-sectional dimension of rubber ring is greater than wheel hub inner ring surface groove size, and rubber ring also is embedded in the groove with enough magnitude of interference.
