Abstract

A kind of ring axially rolled speed reducer circulation thin oil lubricating cooling structure, by lubricating oil pump motor group, the lubricant oil in main lubricating oil tank is conveyed into, in lower cone roller speed reducer, and by oil nozzle to upper, gear and the bearing of lower cone roller speed reducer lubricate, at the lower cone roller speed reducer upper position of frame, middle transition fuel tank is housed, on, lubricant oil in lower cone roller speed reducer relies on gravity to flow to middle transition fuel tank by the return opening of its lower position, oil return Oil pump electrical machinery group sends the lubricant oil of middle transition fuel tank back to main lubricating oil tank again, thus achieve, the circulation of lower cone roller speed reducer lubrication and cooling thin oil, ensure that good lubrication and the cooling of speed reducer.

Description

A kind of ring axially rolled speed reducer circulation thin oil lubricating cooling structure
Technical field
The utility model relates to the circulation thin oil lubricating cooling field of speed reducer, is specifically related to a kind of ring axially rolled speed reducer circulation thin oil lubricating cooling structure.
Background technique
At present, general speed reducer will load a certain amount of lubricant oil before use in speed reducer, relies on gear driven fluid to realize thin oil lubricant and the cooling of speed reducer inside when speed reducer rotates.The whole structure of this speed reducer rare lubrication mode is bad, the gear of floodlubrication fluid and bearing can be lubricated preferably, but do not have the gear of floodlubrication fluid and bearing not to be lubricated preferably, and speed reducer is when using for a long time, lubricating oil temperature raises, thus brings very large negative effect can to the normal use of speed reducer.In the axially rolled device of ring, axially rolled cone roller transmission speed reducer slant setting.If give in speed reducer and add lubricant oil to carry out lubrication and cooling, oil mass has lacked lubrication and cooling poor effect, and oil mass is many can flow out from speed reducer.Therefore, not only lubrication and cooling effect is bad for traditional speed reducer lubrication mode, and also inapplicable for axially rolled cone roller transmission speed reducer.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of ring axially rolled speed reducer circulation thin oil lubricating cooling structure, can meet the lubrication and cooling of the axially rolled speed reducer of ring.
In order to achieve the above object, the technological scheme that the utility model is taked is:
A kind of ring axially rolled speed reducer circulation thin oil lubricating cooling structure, comprise main lubricating oil tank 1, main lubricating oil tank 1 oil outlet is connected with the entrance of two lubricating oil pump motor groups 2 that main lubricating oil tank 1 is installed, the outlet of two lubricating oil pump motor groups 2 is respectively by fuel-displaced hard tube 3, fuel-displaced hose 4 is connected with epicone roller speed reducer 6 with the axially rolled lower cone roller speed reducer 5 of ring, and by oil nozzle, the gear of lower cone roller speed reducer 5 and epicone roller speed reducer 6 and bearing are lubricated, at lower cone roller speed reducer 5 upper position of frame, middle transition fuel tank 9 is housed, in lower cone roller speed reducer 5 and epicone roller speed reducer 6, the lubricating oil outlet of lower position is respectively by oil return hard tube 7, oil return hose assembly 8 is connected with the entrance of middle transition fuel tank 9, the outlet of middle transition fuel tank 9 is by oil return Oil pump electrical machinery group 10, fuel-displaced hard tube 3, fuel-displaced hose 4 is connected with the return opening of main lubricating oil tank 1.
Between described, transition fuel tank 9 is provided with fluid level control device.
Described middle transition fuel tank 9 is placed in the below of lower cone roller speed reducer 5.
The beneficial effects of the utility model are: by circulation thin oil lubricating cooling structure, achieve good lubrication and the cooling of the axially rolled speed reducer of ring.
Accompanying drawing explanation
Accompanying drawing is structure principle chart of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in drawings, a kind of ring axially rolled speed reducer circulation thin oil lubricating cooling structure, comprise main lubricating oil tank 1, main lubricating oil tank 1 oil outlet is connected with the entrance of two lubricating oil pump motor groups 2 that main lubricating oil tank 1 is installed, the outlet of two lubricating oil pump motor groups 2 is respectively by fuel-displaced hard tube 3, fuel-displaced hose 4 is connected with epicone roller speed reducer 6 with the axially rolled lower cone roller speed reducer 5 of ring, and by oil nozzle, the gear of lower cone roller speed reducer 5 and epicone roller speed reducer 6 and bearing are lubricated, at lower cone roller speed reducer 5 upper position of frame, middle transition fuel tank 9 is housed, in lower cone roller speed reducer 5 and epicone roller speed reducer 6, the lubricating oil outlet of lower position is respectively by oil return hard tube 7, oil return hose assembly 8 is connected with the entrance of middle transition fuel tank 9, the outlet of middle transition fuel tank 9 is by oil return Oil pump electrical machinery group 10, fuel-displaced hard tube 3, fuel-displaced hose 4 is connected with the return opening of main lubricating oil tank 1.
Between described, transition fuel tank 9 is provided with fluid level control device.
Described middle transition fuel tank 9 is placed in the below of lower cone roller speed reducer 5.
Working principle of the present utility model is:
The Pipeline transport that lubricant oil is connected with hose 4 by hard tube 3 from main lubricating oil tank 1 enters in the axially rolled lower cone roller speed reducer 5 of ring and epicone roller speed reducer 6 by lubricating oil pump motor group 2 respectively, and by oil nozzle, the gear of lower cone roller speed reducer 5 and epicone roller speed reducer 6 and bearing are lubricated, lubricant oil in lower cone roller speed reducer 5 and epicone roller speed reducer 6 relies on gravity to be flowed out by the return opening of its lower position, the pipeline be connected with oil return hose assembly 8 through oil return hard tube 7 flows to middle transition fuel tank 9, make can not deposit too much lubricant oil in lower cone roller speed reducer 5 and epicone roller speed reducer 6, fluid level control device is after middle transition fuel tank 9 fluid reaches the highest liquid level, start oil return Oil pump electrical machinery group 10, the lubricant oil in middle transition fuel tank 9 is sent back to main lubricating oil tank 1 through piping, after middle transition fuel tank 9 fluid reaches minimum liquid level, oil return Oil pump electrical machinery group 10 stops, avoiding dump pump inhales empty.
The effect of middle transition fuel tank 9 is the lubricant oil in lower cone roller speed reducer 5 and epicone roller speed reducer 6 can be flowed out smoothly, and send main lubricating oil tank 1 back to, thus make lubricating oil pump motor group 2 continuously by lubricant oil input lower cone roller speed reducer 5 and epicone roller speed reducer 6, to make lower cone roller speed reducer 5 and epicone roller speed reducer 6 can obtain good lubrication and cooling.
