Due to hoisting crane common mechanical, building field, its working environment is generally a kind of greasy dirt, muddy environment, therefore extraneous dust etc. can enter into the inside of axis of revolution bearing, be deposited on the inwall of bearing, axis of revolution bearing cavity, strengthened the friction between the inner each parts of axis of revolution bearing, long-term use likely can cause the damage of transmission shaft and bearing or even axis of revolution bearing itself.
Utility model content
Technical problem to be solved in the utility model is to provide one to be lubricated inside for the above-mentioned state of the art, prevents each component wear wherein, the Novel crane axis of revolution bearing increasing the service life.
For achieving the above object, key is to design a kind of lubrication system on axis of revolution bearing, is communicated with extraneous fuel tap inner axis of revolution bearing, is directed to this, and the utility model provides following technical scheme:
A kind of Novel crane axis of revolution bearing, include a seat body, described seat body internal shaping has cavity, in described cavity, be fixed with bearing, described cavity is formed with mounting hole on the outer wall of described seat body, extraneous hoisting crane rotating shaft is fixed in described bearing through described mounting hole, wherein, on the inwall of described cavity, offer oil hole, in described seat body, be also embedded with alemite and safety valve, described alemite one end is located in described oil hole and with described cavity and is communicated with, the other end is fixed with described safety valve, described safety valve is connected with the fuel tap that is positioned at a described seat body external world by oil pipe.
Adopt the axis of revolution bearing of this structure, owing to being provided with alemite, safety valve in a seat body, and above-mentioned parts can be interconnected by oil pipe and extraneous fuel tap, like this, lubricating oil can enter into safety valve by oil pipe, then is flowed into the inner chamber of seat body by oil hole by alemite, bearing surface, bearing and prop up the inwall of seat body cavity and bearing and the junction of axis of revolution between form oil film, thereby reduce wearing and tearing, extended the service life of each parts.
As above-mentioned axis of revolution bearing in the utility model preferably, in described seat body, offer the passage wearing for described oil pipe, described passage is formed with opening on the outer wall of described seat body, described seat body is circumferentially provided with oil sealing along described opening.
Adopt the axis of revolution bearing of this structure, it is to be provided with an opening at the outer wall of a seat body, the inside of propping up seat body is provided with the passage that a fuel feed pipe wears, in the time that oil pipe is drawn from opening, for the lubricating oil of bearing body interior flows backwards from the gap of oil pipe and passage, gap between oil pipe and opening, overflow again, on the outer wall of a seat body, be socketed with oil sealing (seal ring), this oil sealing can be blocked the gap between oil pipe and opening, prevents that the outer wall that lubricating oil is spilled over to axis of revolution bearing from polluting.
As the improvement of above-mentioned axis of revolution bearing in the utility model, on described seat body, offer two blind holes, described blind hole is arranged on the both sides of a described seat body symmetrically, in described blind hole, is provided with negative thread, is provided with some pin-and-holes in the aperture of described blind hole.Like this, just can adopt various ways (be threaded, pin joint) will prop up neatly seat body is fixed.
In sum, compared with prior art, the utility model has the advantage of: in a seat body, be provided with alemite, safety valve, and above-mentioned parts can be interconnected by oil pipe and extraneous fuel tap, like this, can remain that the bearing of bearing body interior and axis of revolution, in lubricating status, have reduced wearing and tearing, improve the performance of product.
