Abstract

The utility model relates to a shock absorbing mechanism, in particular to a shock pad in the shock absorbing mechanism, which is characterized in that the shock pad is in an annular shape and is divided into a plurality of sections along the circumference. The shock pad can absorb the kinetic energy of the external pushing impact of a moving core by deformation well, and reduce noise; and simultaneously, the multi-section sectional structure makes the maintenance very convenient.

Description

Beam

Technical field

The utility model relates to damper mechanism, is specifically related to the beam in a kind of damper mechanism.

Background technique

Usually have damper mechanism in the mechanical structures such as magnetic force device of existing drive core, these damper mechanisms comprise reducing convex shoulder, beam and the beam hold down gag on the moving core, when moving core extrapolation is moved, the reducing convex shoulder of moving core impacts beam, and beam absorbs the kinetic energy that moving core impacts beam by being out of shape.What these damper mechanisms used usually is the all-in-one-piece ring beam that can be set on the moving core, and beam is arranged in the sheath of the band center hole of the center hole of magnetic force device end cap or connection magnetic force device end cap.Because beam is to be close to the center hole wall of magnetic force device end cap or jacket wall, beam lacks the space of distortion when moving core impacts beam.When beam can't be out of shape, the collision of beam and moving core was rigid collision to a great extent.Therefore, there is the big problem of noise in general all-in-one-piece beam, and in addition, this all-in-one-piece beam is an easily damaged parts, need will take off on the driven core of beam and with on the new cushion cover, troublesome poeration is wasted time and energy when maintain and replace.

Summary of the invention

It is little that the purpose of this utility model provides a kind of noise, beam easy to maintenance.

For achieving the above object, the utility model has adopted following technological scheme: a kind of beam, described beam are ring and are divided into some lobes along its circumference.

As shown from the above technical solution, the utility model general integrated type ring beam at present makes split into, the split beam provides the space that holds the beam distortion between the cutting end face of adjacent two lobes, make beam absorb the kinetic energy that moving core extrapolation is impacted by distortion well, reduced noise, simultaneously, because the split structure of its multi-clove type is very convenient when maintenance.

Embodiment

As shown in Figure 1, as one of preferred implementation of the present utility model, some lobes of beam 10 of the present utility model form for the circumference upper edge radial cut at the ring beam 10 of integral body is divided into some fan-shaped section.Preferred scheme is to form three lobes 101,102,103 in that ring beam 10 is cut into three fan-shaped section along A, B, C three places that its circumference is divided into three lobes, described fan-shaped be in plane perpendicular to axial direction project into fan-shaped.

Shown in Fig. 2,3, as one of embodiment of the present utility model, described ring beam 10 is for to be divided into three lobes 101,102,103 along its circumference, the ring through hole of its center hole 11 for passing for moving core 20, left and right sides both ends of the surface 12 are parallel to each other, 13 transition of right cylinder shape curved surface are arranged between the both ends of the surface 12, and beam 10 is pressed abd fixed on by beam supporting base 30 in the step hole of center hole near exterior edge face one side of magnetic force device end cap, is provided with baffle plate 40 before the beam 10.When moving core 20 is extrapolated, the reducing convex shoulder impact baffle plate 40 on the moving core 20, baffle plate 40 compresses beam 10, and beam 10 absorbs by distortion and moves the kinetic energy that core 20 impacts.Just A, B, C three places leave the distortion that the space holds beam 10 to beam 10 between the cutting end face of adjacent two lobes in distinguish place, help the distortion energy-absorbing of beam, thereby reduce noise, simultaneously, because the splitted structure of its multi-clove type is very convenient when maintenance.

Shown in Fig. 4,5, as another kind of embodiment preferred of the present utility model, described ring beam 10 is divided into three lobes 101,102,103 along its circumference, the ring through hole of its center hole 11 for passing for moving core 20, left and right sides both ends of the surface 12 are parallel to each other, arc-shaped surface 13 transition are arranged between the both ends of the surface, and the global shape of beam 10 is the abacus bead shape.It is in the hole of conical surface that beam 10 is placed on the hole wall of offering on the beam supporting base 30, also can be in the hole of cylindroid, is provided with baffle plate 40 before the beam 10.During moving core 20 extrapolations, the reducing convex shoulder impact baffle plate 40 of moving core 20, baffle plate 40 compresses beam 10, and beam 10 is to be placed in the hole of the taper hole wall on the beam supporting base 30, and beam 10 is by top board 40 extrusion-deformation in the tapered bore.Just A, B, C three places leave the distortion that the space holds beam 10 to beam 10 between the cutting end face of adjacent two lobes in distinguish place like this.Arc-shaped surface 13 transition are arranged between the beam both ends of the surface, also leave the distortion that the space holds beam 10 like this between the perisporium of arc-shaped surface 13 and conical socket, thereby further improve the deformability of beam, reduce noise.Simultaneously, the distortion of beam 10 can be subjected to the restriction of taper hole wall, and three lobe beams 101,102,103 can tighten up to center hole 11, clamps moving core 20, further absorbs moving core 20 kinetic energy, reduces noise.

Beam preferable material of the present utility model is a polyurethane, and polyurethane has wear resistance good, and the characteristics of corrosion-resistant and good springiness meet Environmental Conditions demand of the present utility model.

The utility model is not limited to above-mentioned two kinds of embodiments, also comprises other similar embodiments.For example also can be divided into pintongs to beam or more than the pintongs, and center hole of other shapes etc. can be arranged.
