Fig. 2 is according to the sectional view of the utility model embodiment's V-type rubber mount.
Fig. 3 is the drawing of metal upper skeleton.
Fig. 4 is the view of V-type rubber mount.
Embodiment
As shown in Figure 1, the utility model provides a kind of stereogram of V-type rubber mount.Fig. 2 shows according to the sectional view of the utility model embodiment's V-type rubber mount.This V-type rubber mount comprises metal upper skeleton, metal lower skeleton, between wherein said metal upper skeleton and described metal lower skeleton, form a V-shape space, in this V-shape space, use rubber by bonding to described upper skeleton and described metal lower skeleton become an entirety.
Fig. 3 is the drawing of metal upper skeleton, and its left figure is front view, and right figure is the sectional drawing along A-A, and its unit is mm.Metal upper skeleton cross section is V-shape, and the angle angle between the lower surface of two inclination is 60 degree.There is the through hole of diameter 48mm centre, for the connection of equipment.
Fig. 4 is the view of V-type rubber mount.Upper figure is front view, and figure below is plan view.Wherein show metal lower skeleton.The cross section of described metal lower skeleton is V-shape, and the inclined-plane that its upper surface tilts and the angle angle [alpha] of plane are 60 degree (see figure 2)s.
Above-mentioned metallic material can be Q235 steel, No. 45 steel, spheroidal graphite cast iron etc.
Rubber section is V-shape, and its angle of inclination is identical with the tilt angle alpha of the upper surface of metal lower skeleton, is 60 degree.When the vertical bearing load of this V-type rubber mount, rubber is force way compression shear type, because rubber modulus of compression is larger, so this structural-load-carrying capacity is large.
Wherein the upper free surface of rubber is shaped as one section of S shape spline curve, connects upper and lower metal frame; Under rubber, free surface is shaped as circular curve, and wherein metal upper skeleton bottom, with metal lower skeleton upper base surface apart from 30mm, forms a hollow space, and rubber is not filled in this hollow space.This structural feature make this supporting member in the time of oscillating load, act under rubber and metal upper skeleton while moving downward, within the scope of the carrying of design, the space of this vibration damper bottom self just can meet motion deformation requirement, like this installation conditions is required simple, need to not beat macropore at vehicle body frame, can not affect vehicle body frame intensity.
Free surface, rubber left and right shape symmetry is S shape spline curve.
Above-mentioned rubber is the design of free shape up and down, has guaranteed that V-type rubber mount is 3:1:7 in vertical, horizontal, longitudinal ratio of rigidity, and vertical natural frequency is within the scope of 8-10Hz, the vibration insulation request of all directions while meeting rail motor set operation.
