Abstract
The invention discloses a lubricating oil self-circulation type reducer for a cooling tower. The lubricating oil self-circulation type reducer for the cooling tower 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 inside the shell and an oil conveying pipe connected with the oil pump, wherein an oil outlet of the oil pump is connected with the bottom end of the oil conveying pipe; the top end of the oil conveying pipe is communicated with the top of the shell. The lubricating oil self-circulation type reducer for the cooling tower is simple in structure, is convenient to use and maintain, and ensures the lubrication condition of a bearing and a gear inside the reducer through circulation of lubricating oil, thereby ensuring normal use of the 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 technique
Cooling tower is widely used in the industry such as iron and steel, chemical industry in a large number, and retarder can reclaim the important component part of hydraulic turbine of cooling tower as water, guarantees that cooling tower is in optimum Working very important for adjustment rotation speed of fan.But existing retarder generally all adopts oil lubrication, retarder inside is full of lubricant oil, and needs to ensure that lubricant oil liquid level is higher than being up to bearing, but once occur that leakage of oil situation makes oil level lower than highest order bearing, just there is oil starvation situation in retarder, affects the normal operation of retarder; Another kind adopts the grease-added lubrication of lubrication, retarder the topmost part bearing adopts grease lubrication, and oil lubrication is still taked in bottom, once occur that a small amount of leakage of oil makes oil level lower than gear, there will be gear failure phenomenon, and lubricating grease Replacement procedure is complicated, cost is high.Therefore existing lubricating system all existing defects make water can reclaim cooling tower retarder to be easy to occur insufficient lubrication and break 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, affects the problem that retarder normally runs when solving lubrication leakage of oil in current retarder.
Technological scheme of the present invention is:
A kind of lubrication oil self-circulation type reduction gear for cooling tower, comprise housing, be arranged at the output shaft that the input shaft of housing bottom is connected with input shaft with the top being arranged at housing, described retarder also includes the oil pump being arranged at bottom in housing and the transport pipe be connected with oil pump, the oil outlet of described oil pump is connected with the bottom of transport pipe, and the top of transport pipe is communicated with the top of housing.
Advantage of the present invention: the top that the lubricant oil in oil pump can be exported to reducer shell by transport pipe, then lubricant oil drenches in housing from housing tip, lubricant oil trickles from the top in housing to bottom due to gravity, ensure that the bearing be in housing all can contact with lubricant oil with gear, bearing and gear is made to remain lubricating status, even if there is the lubrication that leakage of oil situation does not affect bearing in housing and gear yet in retarder, make retarder have good lubricating status and thermal diffusivity, ensure that the normal use of retarder; And structure of the present invention is simple, practical and easy to maintenance, and fabricating cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
See Fig. 1, a kind of lubrication oil self-circulation type reduction gear for cooling tower, comprise housing 1, be arranged at the output shaft 3 that the input shaft 2 of housing bottom is connected with input shaft 2 with the top being arranged at housing 1, the oil pump 4 being arranged at bottom in housing 1 and the transport pipe 5 be connected with oil pump 4, the oil outlet of oil pump 4 is connected with the bottom of transport pipe 5, the top of transport pipe 5 is communicated with the top of housing 1, and the top of transport pipe 5 is positioned at the top of housing top bearing 6.
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 the final output shaft 3 that drives rotates, oil pump 4 starts simultaneously, in oil pump 4 drive shell, lubricant oil enters transport pipe 3 from the bottom entrance of transport pipe 3, pipeline along transport pipe 3 finally exports through the top of transport pipe 3 successively, the top of reducer shell 1 enters in reducer shell 1, arrive the lubricant oil of housing tip under gravity from the top pouring of retarder, complete the self-loopa process of lubricant oil, make the gear of the bearing in housing and the retarder first half be in lubricating status always, as long as and the lubricating oil of reducer shell 1 inside is for exceeding oil pump 4, lubricant oil can be circulated through oil pump 4 circulation and transport pipe 5, retarder just can ensure normal operation.
Claims (1)
1. a lubrication oil self-circulation type reduction gear for cooling tower, comprise housing, be arranged at the output shaft that the input shaft of housing bottom is connected with input shaft with the top being arranged at housing, it is characterized in that: described retarder also includes the oil pump being arranged at bottom in housing and the transport pipe be connected with oil pump, the oil outlet of described oil pump is connected with the bottom of transport pipe, and the top of transport pipe is communicated with the top of housing.
