The guide bearing fixing device of vertical suspended semi submersible vertical turbine pump

The guide bearing fixing device of vertical suspended semi submersible vertical turbine pump 

A vertical suspended semi submersible vertical turbine pump guide bearing fixing device, comprising a bearing bracket (1) and a guide bearing (2), wherein the guide bearing (2) is installed inside the bearing bracket (1), and the outer circle of the guide bearing (2) and the inner hole of the bearing bracket (1) adopt a transition fit. A key (3) for transmitting frictional torque is provided between the guide bearing (2) and the bearing bracket (1), and the guide bearing (2) is axially fixed in the bearing bracket (1) through a hole with a retaining ring (4). The fixing method of this guide bearing has a simple structure, reliable operation, easy processing, assembly and disassembly, and can be widely used in vertical suspended semi submersible vertical turbine pumps, with good economic and social benefits.
