Abstract
The utility model discloses an improved shaft coupler, which comprises an air bag, an inner connecting disc and an outer connecting disc, wherein the inner connecting disc and the outer connecting disc are arranged on the air bag, and the outer surface of the air bag connected with the inner connecting disc and/or the outer connecting disc is a tooth-shaped surface or the wave-shaped surface. The improved shaft coupler has the advantages that the tooth-shaped or wave-shaped surface is arranged on the combining surface of the inner connecting disc, the outer connecting disc and the air bag, and the contact surface of the inner connecting disc, the outer connecting disc and the rubber air bag is increased, so the bonding force among the inner connecting disc, the outer connecting disc and the rubber air bag is enhanced, and the goal of prolonging the service life is reached.
Description
Background technique
The utility model relates to a kind of coupling, particularly a kind of coupling that is used on the mining machinery.
Technical field
Coupling is to be used for being used on the mining machinery device that links together driving shaft and driven shaft, for example, can be used on the ore crusher, and driving shaft can not separate with driven shaft during machine run, only after machine stops, connection is taken apart, and diaxon could separate.Existing coupling can be divided into rigid coupling, flexible coupling and safety coupling.Wherein, having on the flexible coupling can transmitting movement and the elastic element of torque, this elastic element have in various degree axially, radially, the angular compensatory performance; Also have in various degree vibration damping, buffer function, can improve the service behaviour of transmission system.
The elastic element of flexible coupling generally adopts rubber material; And normally rubber material is made ring-shaped gasbag; Air bag one side is provided with the interior land that is connected with driving shaft, and opposite side is provided with the outer land that is connected with driven shaft, and inside and outside land and air bag directly are adhesively fixed.Because coupling is generally operational under the state of high speed rotating and high pulling torque, air bag is deflected repeatedly and is given birth to heat, causes the Adhesion force between air bag and the metal to descend, thereby causes coupling to be damaged.
The model utility content
The purpose of the utility model is the deficiency that overcomes existing technology, and a kind of long service life, good damping effect, Adhesion force improved coupling big, simple in structure, with low cost are provided.
In order to solve the existing in prior technology problem, the coupling of the utility model comprises air bag and is located at the interior land on the air bag, outer land that the outer surface that said air bag is connected with interior land and/or outer land is toothed surface or wavy surface.
The binding face that land is connected with air bag in said is toothed surface accordingly.
The binding face that said outer land is connected with air bag is toothed surface accordingly.
Said air bag is provided with the valve cock that is used to inflate.
Said air bag is processed by composite rubber material.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is provided with profile of tooth or waveform face through the surface that combines with air bag at inside and outside land, increases the surface of contact of inside and outside land and rubber pneumatic bag, thereby increases the Adhesion force between them, reaches the purpose that improves working life.
Description of drawings
Fig. 1 is that the utility model is connected in the structural representation on driving shaft and the driven shaft;
Fig. 2 is an A bilge construction enlarged view among Fig. 1.
Embodiment
As shown in Figure 1, the coupling of the utility model comprises air bag 1, valve cock 2, interior land 3 and outer land 4, and wherein air bag 1 closes rubber material and processes.For the surface of contact of augmented airbag 1 with interior land 3 and outer land 4, air bag 1 is a toothed surface with interior land 3 bonding places, and air bag 1 is a toothed surface also with the bonding place of outer land 4, like Fig. 2.
During use, charge into air for rubber pneumatic bag 1 by valve cock 2 earlier, make air bag 1 internal pressure reach 3.5kg/cm
2, then interior land 3 being connected with driving shaft, outer land 4 is connected with driven shaft.During machine startup, driving shaft 5 drives driven shaft 6 through coupling and rotates, but the utility model transmitting movement and torque, have in various degree axially, radially, the angular compensatory performance; Also have in various degree vibration damping, buffer function, improve the service behaviour of transmission system.
Above-mentioned toothed surface also can be the male and fomale(M&F) of wavy surface or rule.
Claims (5)
1. an improved coupling comprises air bag and is located at the interior land on the air bag, outer land, and it is characterized in that: the outer surface of said air bag and interior land and/or outer land adhering junction is toothed surface or wavy surface.
2. improved coupling according to claim 1 is characterized in that: the binding face that land is connected with air bag in said is toothed surface accordingly.
3. improved coupling according to claim 1 is characterized in that: the binding face that said outer land is connected with air bag is toothed surface accordingly.
4. according to claim 1,2 or 3 described improved coupling, it is characterized in that: said air bag is provided with the valve cock that is used to inflate.
5. improved coupling according to claim 4 is characterized in that: said air bag is processed by composite rubber material.
