自动复位辅助支承机构
摘要：
本发明涉及自动复位辅助支承机构，包括支承座（1），油缸（2），定位套（3），活塞杆（4），推杆（5），燕尾楔块（8），燕尾导向杆（10），螺杆（12），所述油缸（2）通过定位套（3）固定装置在所述支承座（1）横向的孔洞中，所述油缸（2）与活塞杆（4）相连，所述推杆（6）上套有弹簧（6），所述支承座（1）横向孔洞内设置与孔径相适应的隔套（13），所述燕尾楔块（8）安装在所述隔套（13）内，所述支承座（1）纵向孔洞内设置与孔径相适应的法兰套（9），所述螺杆（12）与所述燕尾导向杆（10）通过螺母（14）螺纹连接。本发明结构紧凑，工作稳定可靠，可以避免因位置浮动产生空隙造成辅助支承失败的问题。
摘要（英）：

The invention relates to an automatic reset auxiliary bearing mechanism which comprises a bearing base (1), an oil cylinder (2), a positioning sleeve (3), a piston rod (4), a push rod (5), a dovetail wedge block (8), a dovetail guide rod (10) and a screw rod (12). The oil cylinder (2) is fixedly arranged in a transverse hole in the bearing base (1) through the positioning sleeve (3). The oil cylinder (2) is connected with the piston rod (4). The push rod (5) is sleeved with a spring (6). A spacer bush (13) adapting to the hole diameter is arranged in the transverse hole of the bearing base (1). The dovetail wedge block (8) is installed in the spacer bush (13). A flange sleeve (9) adapting to the hole diameter is arranged in a longitudinal hole in the bearing base (1). The screw rod (12) is in threaded connection with the dovetail guide rod (10) through a nut (14). The structure is compact, work is stable and reliable, and the problem that auxiliary bearing fails due to the fact that a gap is produced by position flotation can be avoided.
