Vibration reduction rubber pad capable of effectively reducing vibration
The invention discloses a vibration reduction rubber pad capable of effectively reducing vibration, the vibration reduction rubber pad comprises an upper rubber layer and a lower rubber layer, the top of the lower rubber layer is provided with a plurality of fixing columns, the fixing columns are arranged to be of an oval table structure, the fixing columns are evenly distributed on the top of the lower rubber layer, the fixing columns are sleeved with springs, and the springs are arranged on the fixing columns. The spring is arranged to be a rubber spring or a metal common spring, the upper rubber layer is installed on the fixing column through a fixing bolt, a threaded hole is formed in the fixing column, and a through hole is formed in the top of the upper rubber layer. According to the train rail rubber pad, the springs are arranged outside the fixing columns and distributed at equal intervals, the overall elasticity of the train rail rubber pad is improved by means of the characteristics that the elasticity modulus of the springs is small, the springs have large elastic deformation after being loaded, and impact and vibration can be effectively absorbed, and meanwhile the overall elasticity of the train rail rubber pad is improved by means of the principle that the rigidity is increased after the springs are connected in parallel. The overall rigidity of the rubber anti-vibration pad is improved, and the overall bearing capacity is improved.
本发明公开了一种有效减小振动的减振橡胶垫，包括上橡胶层和下橡胶层，所述下橡胶层的顶部设置有若干个固定柱，所述固定柱设置为椭圆台形结构，所述固定柱均匀分布在下橡胶层的顶部，所述固定柱的外部套设有弹簧，所述弹簧设置为橡胶弹簧或金属普通弹簧，所述上橡胶层通过固定螺栓安装在固定柱上，所述固定柱上开设有螺纹孔，所述上橡胶层的顶部开设有通孔。本发明通过在固定柱的外部设置弹簧，使弹簧等间隔分布，利用弹簧弹性模量小，受载后有较大的弹性变形，能有效吸收冲击和振动的特点，进而提高列车轨道橡胶垫的整体弹性，同时利用弹簧并联后刚度增加的原理，增大橡胶减振垫的整体刚度，提高整体承载能力。
