Elevator and grooving equipment
The invention discloses an elevator and grooving equipment, relates to the field of engineering machinery. The elevator and the grooving equipment are used for optimizing the structure of the elevator. The elevator comprises a first mounting base, a second mounting base, a bearing, a first sealing assembly and a second sealing assembly, the first mounting base is provided with a first through hole penetrating through the first mounting base in the axial direction, the second mounting base comprises a first end and a second end, the first end is inserted into the first through hole, in addition, the second end is located outside the first through hole, the bearing is arranged between the outer wall of the first end and the inner wall of the first through hole, the first sealing assembly is arranged at the end part of the first through hole so as to block one end of the first through hole and makes contact with the outer wall of the first end in a dynamic seal mode, the second sealing assembly comprises a deformable part, and the deformable part is connected to the other end of the first through hole in a sealed mode. According to the elevator, a sealing cavity used for containing the bearing is formed, and in addition, pressure self-balance inside and outside the sealing cavity is realized.
本发明公开了一种提引器以及成槽设备，涉及工程机械领域，用以优化提引器的结构。该提引器包括第一安装座、第二安装座、轴承、第一密封组件以及第二密封组件。第一安装座具有贯穿自身轴向方向的第一通孔。第二安装座包括第一端和第二端；第一端插入第一通孔中，且第二端位于第一通孔外部。轴承设于第一端的外壁和第一通孔的内壁之间。第一密封组件设于第一通孔的端部，以封堵第一通孔的一端，第一密封组件与第一端的外壁动密封接触。第二密封组件包括可变形部件，可变形部件与第一通孔的另一端密封连接。上述技术方案提供的提引器，形成了用于容纳轴承的密封腔，且实现了位于密封腔内外的压力自平衡。
