Abstract

The utility model discloses a shaft coupling is inhaled to special high elasticity of universal coupling, initiative flange and universal flange including coaxial setting, still be equipped with dabber and elasticity assembly between initiative flange and the universal flange, dabber and the coaxial setting of initiative flange, and the one end terminal surface of dabber passes through bolt and initiative flange joint, the centre bore cooperation of other end center protrusion and universal flange, the elasticity assembly cover is established at the spindle, the elasticity assembly includes integrated into one piece's steel skeleton and the rubber that shakes, the steel skeleton both ends respectively with initiative flange and universal flange joint. The utility model is used for connect motor and universal joint, under the normal circumstances of transmitting of assurance moment of torsion, can completely cut off the vibration that motor or universal joint produced, effectively prolong the life of shafting spare part, simultaneously when rubber is ageing to be torn, the accessible dabber supports universal joint's dead weight, avoids rotatory damage.

Description

High-elasticity vibration absorption coupler special for universal coupler

Technical Field

The utility model belongs to the technical field of the shaft coupling, concretely relates to special high elasticity of universal joint shakes the coupling.

Background

The universal coupling has the capability of correcting deviation and transmitting torque, and is generally suitable for two transmission shafts connected under the condition of an included angle of an axis. Because there is the axis contained angle between two transmission shafts, can produce certain vibration at the transmission in-process, but universal joint does not possess the function of inhaling the vibrations, when high rotational speed and organic group vibration operating mode, causes the relevant spare part of shafting to damage easily. Therefore, a vibration absorbing coupling is proposed which connects a universal coupling with a motor.

Disclosure of Invention

The utility model aims to solve the technical problem that just is not enough to above-mentioned prior art, provide a special high elasticity of universal joint shakes and shakes shaft coupling, it can be under guaranteeing the normal transmission of moment of torsion, and isolated motor or the vibration that universal joint produced have effectively prolonged the life of shafting spare part.

The utility model adopts the technical proposal that: the utility model provides a special high elasticity of universal joint shakes and shakes shaft coupling, includes coaxial initiative flange and the universal flange that sets up, still be equipped with dabber and elasticity assembly between initiative flange and the universal flange, dabber and the coaxial setting of initiative flange, and the one end terminal surface of dabber pass through bolt and initiative flange joint, and the other end center protrusion cooperates with the centre bore of universal flange, the elasticity assembly cover is established at the dabber, the elasticity assembly includes integrated into one piece's steel skeleton and shakes the rubber, steel skeleton both ends respectively with initiative flange and universal flange joint.

Preferably, the driving flange is connected with the motor, and the universal flange is connected with a flange of the universal coupling.

The utility model is used for connect motor and universal joint, under the normal circumstances of transmitting of assurance moment of torsion, can completely cut off the vibration that motor or universal joint produced, effectively prolong the life of shafting spare part, simultaneously when rubber is ageing to be torn, the accessible dabber supports universal joint's dead weight, avoids rotatory damage.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. an active flange; 2. a universal flange; 3. a mandrel; 4. an elastic assembly; 41. a steel skeleton; 42. and vibration absorbing rubber.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Examples

As shown in fig. 1, the special high-elasticity vibration absorption coupler for the universal coupler provided by this embodiment includes a driving flange 1, a universal flange 2, a mandrel 3 and an elastic assembly 4 which are coaxially disposed, one end of the driving flange 1 is connected with a motor, the other end is connected with the mandrel 3 through a bolt, a protrusion matched with a central hole of the universal flange 2 is formed at the center of one end of the mandrel 3, which is far away from the driving flange 1, the protrusion of the mandrel 3 extends into the central hole of the universal flange 2 and is in universal fit with the central hole, one end of the universal flange 2, which is far away from the mandrel 3, is connected with a flange of the universal coupler, the elastic assembly 4 includes a steel skeleton 41 and rubber, the rubber forms a whole with the steel skeleton 41 after being vulcanized, the elastic assembly 4 is sleeved outside the mandrel 3, one end of the elastic assembly 4 is connected with the driving flange 1, and the other end is connected with the universal flange 2.

The working principle is as follows: because the rubber can bear shear stress to a certain degree, normal torque transmission can be realized, and simultaneously because the rubber also has a damping function, the vibration generated by the motor or the universal coupling can be isolated, namely vibration absorption can be realized, so that the service lives of other shafting parts are prolonged; when the rubber is aged and torn, the spindle 3 arranged through the rubber can support the universal coupling, so that the rotation damage is avoided.

The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and the utility model should be covered in the protection scope of the present invention.
