Abstract
The invention discloses a speed reducer used for a lubricating oil self circulation type cooling tower. The speed reducer comprises a shell, an input shaft arranged at the bottom of the shell, an output shaft arranged at the top of the shell and connected with the input shaft, an oil pump arranged at the inner lower part of the shell, and an oil delivery pipe connected with the oil pump, wherein the oil outlet of the oil pump is connected with the bottom end of the oil delivery pipe, and the top end of the oil delivery pipe communicates with the top of the shell. The speed reducer is simple in structure and convenient to use and maintain, and the lubricating conditions of bearings and gears in the speed reducer are ensured by the circulation of the lubricating oil, thus ensuring normal use of the speed reducer for the cooling tower.
Description
Technical field
The present invention relates to speed reducer used for cooling power field, specifically a kind of lubrication oil self-circulation type reduction gear for cooling tower.
Background technology
Cooling tower is widely used in the industry such as iron and steel, chemical industry in a large number, and decelerator is as hydraulic energy recuperation hydraulic turbine of cooling tower
For regulation rotation speed of fan, important component part, guarantees that cooling tower is in optimum Working particularly significant.But existing decelerator
The general oil lubrication that all uses, decelerator inside is full of lubricating oil and it needs to ensure lubricating oil liquid level higher than being up to bearing,
But once occur that leakage of oil situation makes oil level be less than highest order bearing, decelerator exists for oil starvation situation, affects decelerator
Properly functioning；Another kind is to use to lubricate grease-added lubrication, and decelerator topmost bearing uses grease lubrication, and bottom is still adopted
Take oil lubrication, once occur that a small amount of leakage of oil makes oil level be less than gear, it may appear that gear failure phenomenon, and grease is more
Change complex process, cost height.The most existing lubricating system all existing defects allow the water to reclaim cooling tower decelerator and are easy to
Occur that insufficient lubrication breaks down.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lubrication oil self-circulation type reduction gear for cooling tower, solves at present
Affect, during lubrication leakage of oil, the problem that decelerator is properly functioning in decelerator.
The technical scheme is that
A kind of lubrication oil self-circulation type reduction gear for cooling tower, the power shaft including housing, being arranged at housing bottom and being arranged at
The output shaft that the top of housing is connected with power shaft, described decelerator also include be arranged at bottom in housing oil pump and with
The petroleum pipeline that oil pump connects, the oil-out of described oil pump is connected with the bottom of petroleum pipeline, the top of petroleum pipeline and the top of housing
Portion connects.
Advantages of the present invention: the lubricating oil in oil pump can be exported the top to reducer shell, then by petroleum pipeline
Lubricating oil drenches in housing from housing tip, and lubricating oil trickles to bottom due to gravity top in housing, it is ensured that
The bearing being in housing all can contact with lubricating oil with gear, makes bearing and gear remain lubricating status, even if slowing down
There is bearing and the lubrication of gear that leakage of oil situation nor affects in housing in device, make decelerator have good lubricating status and
Thermal diffusivity, it is ensured that the normal use of decelerator；And the simple in construction of the present invention, practical and easy to maintenance, and cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Seeing Fig. 1, a kind of lubrication oil self-circulation type reduction gear for cooling tower, including housing 1, the input that is arranged at housing bottom
Axle 2 and be arranged at the output shaft 3 that the top of housing 1 is connected with power shaft 2, is arranged at oil pump 4 and and the oil pump of bottom in housing 1
4 petroleum pipelines 5 connected, the oil-out of oil pump 4 is connected with the bottom of petroleum pipeline 5, and the top of petroleum pipeline 5 connects with the top of housing 1
Lead to, and the top of petroleum pipeline 5 is positioned at the top of housing top bearing 6.
The use principle of the present invention: the power shaft 2 of speed reducer used for cooling power starts to rotate, and power shaft 2 drives reducing gearbox
Body 1 internal gear system rotates and finally drives output shaft 3 to rotate, and oil pump 4 starts simultaneously, lubricating oil in oil pump 4 drive shell
Entering petroleum pipeline 3 from the bottom entrance of petroleum pipeline 3, the final top through petroleum pipeline 3 the most successively of pipeline along petroleum pipeline 3 exports, subtracts
The top of speed device housing 1 enters in reducer shell 1, arrives the lubricating oil of housing tip under gravity from the top of decelerator
Under portion is drenched, complete the self-loopa process of lubricating oil so that bearing and the gear of the decelerator first half in housing are constantly in
Lubricating status, as long as and lubricating oil within reducer shell 1 is for exceeding oil pump 4, make lubricating oil can through oil pump 4 circulation and
Petroleum pipeline 5 circulates, and decelerator is it is ensured that properly functioning.
