Abstract
The invention discloses a lubricating oil self-circulation type speed reducer for a cooling tower. The lubricating oil self-circulation type 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 on the lower portion of the inside of the shell, and an oil-conveying pipe connected with the oil pump. An oil outlet of the oil pump is connected with the bottom end of the oil-conveying pipe, and the top end of the oil-conveying pipe communicates with the top of the shell. The lubricating oil self-circulation type speed reducer is simple in structure and convenient to use and maintain, the lubrication condition of a bearing and a gear inside the speed reducer is guaranteed through circulation of lubricating oil, and thus normal use of the speed reducer for the cooling tower is ensured.
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 industries such as iron and steel, chemical industry in a large number, for regulation rotation speed of fan, decelerator, as the important component part of hydraulic energy recuperation hydraulic turbine of cooling tower, guarantees that cooling tower is in optimum Working particularly significant.But existing decelerator typically all adopts oil lubrication, full of lubricating oil and it needs to ensure that lubricating oil liquid level is higher than to be up to bearing inside decelerator, but Yi Dan oil leak situation occurring so that when oil level is less than highest order bearing, decelerator there is oil starvation situation, the normal operation of impact decelerator；Another kind is using the grease-added lubrication of lubrication, decelerator topmost bearing adopts grease lubrication, and oil lubrication is still taken in bottom, makes oil level be less than gear once a small amount of oil leak, gear failure phenomenon occurs, and lubricating grease Replacement procedure is complicated, high cost.Therefore existing lubricating system all existing defects allow the water to recovery cooling tower decelerator and are easy to insufficient lubrication and break down.
Content 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 the problems, such as that during lubrication oil leak in current decelerator, impact decelerator normally runs.
The technical scheme is that：
A kind of lubrication oil self-circulation type reduction gear for cooling tower, the output shaft that the input shaft including housing, being arranged at housing bottom and the top being arranged at housing are connected with input shaft, described decelerator is also included and is arranged at the oil pump of bottom and the petroleum pipeline being connected with oil pump in housing, the oil-out of described oil pump is connected with the bottom of petroleum pipeline, and the top of petroleum pipeline is connected with the top of housing.
Advantages of the present invention：Lubricating oil in oil pump can be exported to the top of reducer shell by petroleum pipeline, then lubricating oil drenches in housing from housing tip, lubricating oil due to gravity, trickle to bottom by the top in housing, ensure that the bearing being in housing all can be contacted with lubricating oil with gear, bearing and gear is made to remain lubricating status, even if there is the lubrication of the bearing that oil leak situation nor affects in housing and gear in decelerator, decelerator is made to have good lubricating status and thermal diffusivity it is ensured that the normal use of decelerator；And the structure of the present invention is simple, practical and easy to maintenance, and low manufacture cost.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
See Fig. 1, a kind of lubrication oil self-circulation type reduction gear for cooling tower, the output shaft 3 that the input shaft 2 including housing 1, being arranged at housing bottom and the top being arranged at housing 1 are connected with input shaft 2, it is arranged at the oil pump 4 of bottom in housing 1 and the petroleum pipeline 5 being connected with oil pump 4, the oil-out of oil pump 4 is connected with the bottom of petroleum pipeline 5, the top of petroleum pipeline 5 is connected with the top of housing 1, and the top of petroleum pipeline 5 is located at the top of top bearing 6 in housing.
The use principle of the present invention：The input shaft 2 of speed reducer used for cooling power starts to rotate, input shaft 2 drives reducer shell 1 internal gear system to rotate and finally drives output shaft 3 to rotate, oil pump 4 starts simultaneously, in oil pump 4 drive shell, lubricating oil enters petroleum pipeline 3 from the bottom entrance of petroleum pipeline 3, the final top export through petroleum pipeline 3 successively of pipeline along petroleum pipeline 3, the top of reducer shell 1 enters in reducer shell 1, the lubricating oil reaching housing tip is under gravity from the pouring of the top of decelerator, complete the self-loopa process of lubricating oil, the bearing in housing and the gear of the decelerator first half is made to be constantly in lubricating status, as long as and the lubricating oil within reducer shell 1 is to exceed oil pump 4, lubricating oil is enable to circulate through oil pump 4 circulation and petroleum pipeline 5, decelerator is it is ensured that normal run.
Claims (1)
