Abstract
The utility model discloses a novel elastic pin, which is provided with a pin body, wherein the pin body is provided with a fixed end and a movable end, and an elastic layer is sleeved arranged on the outer layer of the pin body. The novel elastic pin is characterized in that the fixed end is cylindrical, the movable end of the pin body is spherical, and the elastic layer is tightly coated on the outer side surface of the pin body. Compared with the prior art, the novel elastic pin is simple in structure, flexible and convenient in assembly and large in transmission torque, can not only have functions of buffering and vibration reduction but compensate displacement of two axes. The novel elastic pin is applicable for coupling of a water turbine of a power station.
Description
Technical field
The utility model belongs to the coupling technical field, is specifically related to a kind of novel elastic pin.
Background technique
Coupling connects the pin that uses in the existing water turbine, has the rigidity pin to connect, and this connection is to the requirement that the comparison harshness is installed of water turbine, and axial position can not have any adjusting; Flexible pin connects, and the benefit of resilient connection is can be flexibly to many fulcrums unit installation requirement, but resilient coupling in the past adopts rubber ring to be used in combination with bolt more, and this structure can only be transmitted very little moment of torsion, and rubber ring is very fragile.
Summary of the invention
Be to solve the above-mentioned defective that prior art exists, it is a kind of simple in structure that the purpose of this utility model is to provide, assemble flexible, the novel elastic pin that transmitting torque is big.
For achieving the above object, the technical solution adopted in the utility model is: this novel elastic pin, has shank, shank has fixed end and movable end, the shank skin is set with elasitic layer, it is characterized in that: the fixed end of described shank is cylindric, and the movable end of shank is a spherical shape, and described elasitic layer closely wraps up the outer side surface of shank.
Described elasitic layer is a reinforced nylon.
The outer surface of described shank is a shape of threads.
Adopt the beneficial effect of technique scheme to be: this novel elastic pin has two kinds of materials to constitute, skin is an elasitic layer, material is a reinforced nylon, on the shank that it is made of steel core in the inside by die casting, for nylon is combined with shank firmly, make shape of threads at the surperficial car of shank, the fixed end of shank is processed into cylindric, movable end is processed into spherical shape, soundness and tightness when increasing work.This spring column pin has the following advantages: 1. do not changing design coupling boundary dimension, quantity with bolt, increase the diameter of steel core effectively, increased the moment of torsion that transmits, adopt the Placement of spherical elasitic layer, do not change the function of elastic coupling flexible coupling, can have the function of buffering and vibration damping, can compensate the displacement between two axial lines again.2. the utilization of this structure reduces rubber ring, has avoided because of ageing of rubber, and is fragile, non-maintaining characteristics.3. this spring column pin has promptly solved the resilient connection problem, has solved again simultaneously to transmit than the high pulling torque problem, trys out in a plurality of power stations, assembles flexiblely, and using effect is good.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of spring column pin user mode.
Embodiment
As Fig. 1, the pin of novel elastic shown in 2, has shank, shank has fixed end 1 and movable end 3, the shank skin is set with elasitic layer 2, the fixed end 1 of described shank is cylindric, the movable end 3 of shank is a spherical shape, elasitic layer is a reinforced nylon, on the shank that it is made of steel core in the inside by die casting, makes elasitic layer closely wrap up the outer side surface of shank, the outer surface car of shank is made shape of threads, soundness during increase work and tightness. from Fig. 2 user mode figure, find out, in the quantity that does not change design coupling boundary dimension and bolt, increase the diameter of shank steel core effectively, increase the moment of torsion that transmits, adopted the Placement of spherical elasitic layer, do not changed the function of elastic coupling flexible coupling, can have the function of buffering and vibration damping, can compensate the displacement between two axial lines again.
Claims (3)
1. a novel elastic pin has shank, and shank has fixed end and movable end, the shank skin is set with elasitic layer, it is characterized in that: the fixed end of described shank is cylindric, and the movable end of shank is a spherical shape, and described elasitic layer closely wraps up the outer side surface of shank.
2. novel elastic pin according to claim 1 is characterized in that: described elasitic layer is a reinforced nylon.
