Abstract
The utility model relates to an intermediate bearing capable of being operated under wet installation condition. The intermediate bearing comprises a bearing bracket, a bearing casing and a shaft, and is characterized in that the high molecular bearing is formed between the bearing casing and the shaft, and an external water outlet is formed on the shaft relative to the contact surface of the high molecular bearing. An external water inlet pipe is formed on the central axis of the shaft. The intermediate bearing has the advantages that clean water is adopted for lubrication, the friction is small, the wear resistant property is good, the service life is long, the load supporting is high, the intermediate bearing has proper amount of elastic-plasticity, can distribute stress onto a wider contact surface, improve the bearing capacity of the bearing, perform self-lubricating, form a transfer membrane during the operation process to play the role of shaft protection, and has no shaft-blocking phenomenon.
Description
Technical field
The utility model relates to a kind of at the intermediate bearing that can move under the wet type installation conditions.
Background technique
Intermediate bearing on the present axial-flow pump transmission shaft generally uses rolling bearing, but rolling bearing needs grease lubrication, can only under the dry type environment, normally move, if there is water to enter bearing, and the necrosis of easily getting rusty.The rolling bearing that therefore if can improve the axial-flow pump transmission shaft is lubricated with clear water, then can greatly make things convenient for installing and using of axial-flow pump.
Summary of the invention:
The purpose of this utility model is that the intermediate bearing on the axial flow pump drive shaft needs grease lubrication in the solution prior art, and the downright bad existing problem in case water inlet is got rusty provides a kind of at the intermediate bearing that can move under the wet type installation conditions.The utility model design, a kind of at the intermediate bearing that can under the wet type installation conditions, move, comprise bearing bracket stand, bearing shell, axle, it is characterized in that: between bearing shell and axle, for the macromolecule bearing, offering external water out on respect to macromolecule bearing surface of contact on the axle.Water receiving intake pipe outside on the medial axis of axle, offering.The utility model has the advantages that and utilize clear water to be lubricated; low friction, wear-resisting property is good, long service life; carry well-to-do; an amount of elastoplasticity is arranged, can with stress distribution on the surface of contact of broad, improve the bearing capacity of bearing; selflubricating; in operation process, can form transfer membrane, play the effect of protection axle, not have and sting a phenomenon.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
Comprise bearing bracket stand 1, bearing shell 2, axle 3 among the figure, it is characterized in that: between bearing shell and axle, be macromolecule bearing 4, offering external water out 5 on respect to macromolecule bearing surface of contact on the axle.Water receiving intake pipe outside on the medial axis of axle, offering (not drawing among the figure).
During operation, utilize external clear water water receiving intake pipe outside the medial axis of axle offers to insert, external water out flows on the macromolecule bearing surface of contact on by axle, finishes the lubricated of clear water.
Claims (2)
1. one kind at the intermediate bearing that can move under the wet type installation conditions, comprises bearing bracket stand, bearing shell, axle, it is characterized in that: be the macromolecule bearing between bearing shell and axle, offering external water out on respect to macromolecule bearing surface of contact on the axle.
2. described a kind of at the intermediate bearing that can under the wet type installation conditions, move by claim 1, it is characterized in that: water receiving intake pipe outside on the medial axis of axle, offering.
