The invention discloses a high-temperature-resistant and corrosion-resistant spherical support with a metal friction surface. The high-temperature-resistant and corrosion-resistant spherical support comprises an upper support body 1, a spherical crown lining plate 2 and a lower support body 3 which are sequentially arranged. Wherein the upper support 1 is fixed on a girder through the anchor bolt assembly 5, the lower support 3 is fixed on an abutment through the foundation bolt 4, and the spherical crown lining plate 2 is located in the lower support 3. The upper support plate 1 and the lower support plate 3 are made of duplex stainless steel, the spherical crown lining plate 2 adopts copper alloy as a solid self-lubricating material, and compared with a sliding plate made of a high polymer material, the bearing capacity of the spherical crown lining plate 2 is higher, and the bearing safety redundancy is larger; the top and the bottom of the spherical crown lining plate 2 directly form a friction pair with the upper support 1 and the lower support 3 respectively, a sliding plate made of a high polymer material in a common support is replaced, the friction coefficient of the friction pair under 45 Mpa is smaller than or equal to 0.11, the design requirement of the spherical support is met, and the spherical support is made of an alloy material, can keep stable performance in a high-temperature corrosion marine climate environment, and has a good application prospect. And the service life of the spherical support is greatly prolonged.
本发明公开了一种耐高温抗腐蚀的金属摩擦面球型支座，包括依次设有的上支座1、球冠衬板2及下支座3；其中上支座1通过锚栓组件5固定在大梁上，下支座3通过地脚螺栓4固定在墩台上，球冠衬板2位于下支座3内。所述上支座板1、下支座板3采用双相不锈钢制成，球冠衬板2采用铜合金作为固体自润滑材料，相比高分子材料滑板，其承载能力更高，承载的安全冗余更大；通过球冠衬板2顶底部分别与上支座1、下支座3直接组成摩擦副，取代了一般支座中高分子材料制成的滑板，其摩擦副在45Mpa下的摩擦系数≤0.11，满足了球面支座的设计需求，且采用合金材料制成，能够在高温腐蚀的海洋气候环境下保持性能稳定，大大延长了球形支座的使用寿命。
