Abstract
The utility model relates to the field of mechanical shock absorption, in particular to a shock pad with a good impact resistance and an obvious noise reduction effect. The shock pad adopts the following technical scheme: the shock pad is annular and is provided with a center hole, and a reinforcing plate is arranged in the shock pad. When a movable iron core spindle directly strikes the shock pad, the striking kinetic energy of the movable iron core spindle can be absorbed through the transformation of the movable iron core spindle in the impacting moment due to the elasticity of the shock pad, thereby remarkably reducing the noise made in the striking process. The supporting function of the reinforcing plate obviously improves the stability of the shock pad integrate, thereby prolonging the service life of the shock pad.
Description
Technical field
The utility model relates to the mechanical shock absorption field, is specifically related to a kind of beam.
Background technique
At present, two damper mechanisms that drive the magnetic force device in the lift machine hub type brake are extensive use of beam, general beam is provided in a side of in the center bore of magnetic force device end cap and is set in the front end of the moving iron core mandrel of magnetic force device, is close to the hole wall of the center bore of magnetic force device end cap simultaneously.The patent No. is in the patent documentation of ZL200520135516.3, when moving axially in the moving center bore of iron core mandrel at end cap, the convex shoulder at the moving iron core mandrel reducing place baffle plate that can clash, baffle plate impacts beam again, and beam absorbs bump kinetic energy and reduces noise by distortion.Yet baffle plate and moving iron core mandrel all are metalworks and are rigid collision, can produce huge noise, and baffle plate are huge to the impulsive load of beam itself, and the intensity of beam is limited, very easily causes the damage of beam, and working life is limited.
The model utility content
The purpose of this utility model provides the strong and tangible beam of noise reduction of a kind of impact resistance.
For achieving the above object, the utility model by the following technical solutions, beam ringwise and be provided with center hole, the inside of beam is provided with stiffening plate.
By above technological scheme, stiffening plate is set up in the inside of beam, when moving iron core mandrel directly clashes into beam, because beam has certain elasticity, can can reduce the noise that produces in the collision process greatly clashing into the impact kinetic energy of moment by the moving iron core mandrel of distortion absorption.While is owing to the supporting effect of stiffening plate, thereby the stability that can significantly improve beam integral body has longer working life.

Embodiment
A kind of beam, described beam 10 ringwise and be provided with center hole 11, the inside of beam 10 is provided with stiffening plate 12.The center hole 11 of described annular beam 10 is the ring through holes that pass for moving iron core mandrel, and the stiffening plate 12 of beam 10 inside is equivalent to the effect of support frame, thereby the intensity that can significantly improve beam 10 has higher impact resistance.Stiffening plate 12 is located at the inside of beam 10, has avoided the direct collision with moving iron core mandrel, can reduce the noise that produces in the knockout process greatly.
Described stiffening plate 12 is positioned at the place, a side end face of beam 10, this side end face is exactly the surface of contact of moving iron core mandrel and beam collision, stiffening plate 12 is located at this end face can makes just absorb impact kinetic energy its moment at moving iron core mandrel bump beam 10, beam 10 reduces itself suffered impact kinetic energy by being out of shape rapidly.
Described stiffening plate 12 ringwise and the peripheral profile concave-convex surface, recess profile 121 is fan-shaped and circumferential symmetric arrangement.Be exactly specifically with the stiffening plate 12 of annular along its circumference radially cutting be plurality of sections, so just formed fan-shaped recess profile 121, be that it is cut into three sections in this programme.The stiffening plate 12 of this structure can absorb the impact kinetic energy of moving iron core mandrel to beam 10 to greatest extent, it is more firm that stiffening plate 12 is connected with the entity of beam 10 in beam 10 inside, prevents that the two separates beam 10 under the situation of unbalance stress.12 pairs of whole beams 10 of stiffening plate have just played good supporting effect like this, have effectively improved the stability of the integral body of beam 10.
As one of specific embodiment of the utility model, the perisporium 13 of described beam 10 is cylindric, is arc transition between perisporium 13 and the end face 14 away from stiffening plate 12 1 sides.The perisporium 13 of beam 10 is to fit with the end cap inwall of damper mechanism, and when moving iron core mandrel clashed into beam 10, this arc transition section can provide bigger deformation space, helps the distortion energy-absorbing of beam 10, thereby has good noise reduction.
As another kind of specific embodiment of the present utility model, the perisporium 13 of described beam 10 is coniform, and is little near the diameter of the perisporium 13 of stiffening plate 12 1 sides, away from the diameter of the perisporium 13 of stiffening plate 12 1 sides big and and this side end face 14 between be arc transition.The perisporium of beam 10 is tightr that the coniform end cap inwall that can make itself and shock-damping structure fits, when beam 10 is subjected to the bump of moving iron core mandrel, the stiction that need overcome between the end cap inwall of the perisporium 13 of taper of beam 10 and damper mechanism could promote it, beam 10 is in the process that absorbs bump kinetic energy generation deformation simultaneously, the end cap inwall can make beam 10 tighten up and clamp moving iron core mandrel to center hole 11 to the reaction force of beam 10, further absorb the kinetic energy of moving iron core mandrel, the effect that reduces noise is more obvious.
Because polyurethane material has the characteristics of good, the corrosion-resistant and good springiness of wear resistance, beam 10 described in the utility model is preferentially selected polyurethane material for use, stiffening plate 12 is cold rolled sheet and its plating zinc on surface or polycarbonate (PC), polycarbonate (PC) is generally the engineering plastics of import, has the characteristics of impact resistance height and favorable mechanical performance.
