Abstract
The utility model discloses a lubrication oil self-circulation type reduction gear for a cooling tower. The lubrication oil self-circulation type reduction gear for the cooling tower comprises a shell, an input shaft, an output shaft, an oil pump and an oil delivery pipe, wherein the input shaft is arranged at the bottom of the shell, the output shaft is arranged at the top of the shell and is connected with the input shaft, the oil pump is arranged at the lower part inside the shell, the oil delivery pipe is connected with the oil pump, an 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 is communicated with the top of the shell. The lubrication oil self-circulation type reduction gear for the cooling tower, disclosed by the utility model, has a simple structure and is convenient to use and maintain, the lubrication condition of a bearing and a gear in the reduction gear is ensured through the circulation of lubrication oil, and thus the normal use of the reduction gear for the cooling tower is ensured.
Description
Technical field
The utility model relates to used for cooling tower retarder field, specifically is a kind of lubricant oil self-circulation type used for cooling tower retarder.
Background technique
Cooling tower is widely used in industries such as iron and steel, chemical industry in a large number, and retarder can reclaim the important component part of cooling tower water turbine as water, and to guarantee that cooling tower is in optimum Working very important for regulating rotation speed of fan.But two kinds of lubricating systems of the general employing of existing retarder; A kind of is to adopt oil lubrication; In a single day retarder inside is full of lubricant oil, and needs to guarantee that the lubricant oil liquid level is higher than the highest order bearing, makes when oil level is lower than the highest order bearing but the leakage of oil situation occurs; Just there is the oil starvation situation in retarder, influences the normal operation of retarder; Another kind is to adopt lubricant oil grease-added lubricated, and retarder the topmost part bearing adopts grease lubrication, and oil lubrication is still taked in the bottom; Make oil level be lower than gear in case a small amount of leakage of oil occurs; Gear can occur and damage phenomenon, and lubricating grease is changed complex process, the cost height.Therefore existing lubricating system all exists defective to make water can reclaim the cooling tower retarder to be easy to insufficient lubrication occur and to break down.
The model utility content
The technical problem that the utility model will solve provides a kind of lubricant oil self-circulation type used for cooling tower retarder, influence the problem that retarder normally moves when solving in the present retarder lubricant oil leakage of oil.
The technological scheme of the utility model is:
Lubricant oil self-circulation type used for cooling tower retarder; The output shaft that the input shaft that comprise housing, is arranged at housing bottom and the top that is arranged at housing are connected with input shaft; Described retarder also includes the oil pump and the transport pipe that is connected with oil pump that is arranged at bottom in the housing; 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.
The advantage of the utility model: the top that can the lubricant oil in the oil pump be delivered to reducer shell through transport pipe; Lubricant oil drenches in the housing from the housing top then; Lubricant oil trickles to the bottom from the top in the housing owing to gravity; Guaranteed that the bearing that is in the housing all can contact with lubricant oil with gear, made bearing and gear remain lubricating status, even retarder exists the leakage of oil situation also not influence the lubricated of interior bearing of housing and gear; Make retarder have good lubricating status and thermal diffusivity, guaranteed the normal use of retarder; And the utility model is simple in structure, and operation and maintenance is convenient, and fabricating cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
See Fig. 1; Lubricant oil self-circulation type used for cooling tower retarder; Comprise housing 1, be arranged at housing 1 bottom input shaft 2, be arranged at the output shaft 3 that the top of housing 1 is connected with input shaft 2, the oil pump 4 and the transport pipe 5 that is connected with oil pump 4 that is arranged at bottom in the housing 1, 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.
The use principle of the utility model: used for cooling tower input shaft of speed reducer 2 begins to rotate; Input shaft 2 drives the rotation of reducer shell 1 internal gear system and the final output shaft 3 that drives rotates; Oil pump 4 starts simultaneously, and oil pump 4 drive shell internal lubrication oil get into transport pipe 3 from the bottom inlet of transport pipe 3, gets in the reducer shell 1 through the top of the outlet of the top of transport pipe 3, reducer shell 1 successively along the pipeline of transport pipe 3 is final; Under the lubricant oil that arrives the housing top drenches from the top of retarder under action of gravity; Accomplished the self-loopa process of lubricant oil, made that the bearing in the housing is in lubricating status with the gear of the retarder first half always, and as long as the inner lubricant oil liquid level of reducer shell 1 above oil pump 4; Lubricant oil can be circulated through oil pump 4 and transport pipe 5, and retarder just can guarantee normal operation.
Claims (1)
