Embodiment Construction
[0017] The self-aligning sliding bearing includes the bearing seat body 1, the sliding bearing 2, the bolt hole 3, the disassembly hole 4, and the oil injection hole 5; the bearing seat body and the damper frame are fixed with bolts, and the sliding bearing is connected with the blade shaft, in the bearing seat The hole is radially square with disassembly holes, and the oil injection hole is set in the bore of the bearing housing and perpendicular to the length of the bearing housing; the sliding bearing is connected with the blade shaft to fix the blade shaft on the one hand, and complete the blade shaft on the other hand. Rotating action: A disassembly hole is arranged in the inner hole of the bearing seat along the radial square. The sliding ball with a spherical outer circle is installed into the inner hole of the bearing seat through this position, and then rotated at any angle to ensure that it will not fall off during normal use. The sliding ball of the sliding bearing is...
