Description
Technical field
The present invention relates to a kind of oil stifled, be specifically related to a kind of oil level peep hole clean oil and block up.
Background technique
Gearbox, can quantitative refueling when car load rolls off the production line, and oil both domestic and external is stifled is substantially all metallic material, and connecting thread is tapered thread or straight thread, and oily plug portion is interior six sides and outer hexagonal structure, also has tetragonal inside and outside some oily plug portion.At present, domestic mechanical gear box is observed on oilhole and is not also seen that the clean oil can observing oil level blocks up, when after-sales service, to products such as the mechanical gear boxes not having assembly lube level sensor, the equipment that service station is not quantitatively added with, can only lean on attendant rule of thumb to refuel with feeling, so cannot know that oil mass is added or adds few, user cannot know oil mass, and where this is added in, and user refuels the high temperature fault that improper meeting causes saggar or causes.The replacement cycle of oil product generally carries out according to distance travelled or running time, in fact, oil product is changed and be determined with the change of oil product color more accurately, when oil product becomes aterrimus by yellow light tone, and oil viscosity retrogradation, at this moment should change oil product in time, existing technology needs to open gearbox or drain the oil to determine, operation inconvenience.
Summary of the invention
In order to solve the problems of the prior art, the present invention proposes one can solve problem improperly of refueling, and avoids causing saggar or causing high temperature fault, is convenient to the change observing oil product color simultaneously, judge whether oil product goes bad, the oil level peep hole clean oil of reasonable standard oil product replacement cycle blocks up.
In order to realize above object, the technical solution adopted in the present invention is: comprise the oil be arranged on the horizontal oil level peep hole of case of transmission and block up body, the stifled body of oil is the cylindrical hollow structure of both ends open, the lower end mouth that described oil blocks up body is communicated with the horizontal oil level peep hole of case of transmission, the upper end-hole of the stifled body of oil is provided with transparent oil cap, and described transparent oil cap and oil block up that body is airtight to be connected, when refueling to speed changer, fluid can enter in the cavity of the stifled body of oil, and can observe fluid by transparent oil cap.
Described transparent oil cap is set to hemispheric hollow-core construction, and the bottom of hemispheric hollow-core construction is provided with annular plane, and the upper end-hole that annular plane and oil block up body is fixedly connected with, and fluid can be entered in the hemi-spherical cavities of transparent oil cap by the stifled body of oil.
The upper end-hole that the annular plane of described transparent oil cap and oil block up body is riveted.
Be provided with protective housing in described transparent oil cap, arrange space between protective housing and transparent oil cap, fluid can be entered in the hemi-spherical cavities of transparent oil cap by described space.
Described protective housing is hemispheric hollow-core construction, and the bottom of hemispheric hollow-core construction is provided with the quadrangular plan of band concave edge, and quadrangular plan is connected with transparent oil cap, forms the space being used for fluid and flowing between the concave edge of quadrangular plan and transparent oil cap.
Described transparent oil cap inwall is provided with annular groove, and described quadrangular plan is embedded in described annular groove.
Described oil blocks up body underpart and is provided with screw thread for connecting the horizontal oil level peep hole of case of transmission.
Described screw thread is straight thread or tapered thread.
Described oil blocks up body upper end portion and is provided with hexagonal flange plane for wrench operated.
Described oil blocks up external wall and is provided with circular groove, is provided with seal ring in circular groove.
Compared with prior art, gearbox, when car load rolls off the production line, needs quantitative refueling, and when after-sales service, service station does not have the equipment of quantitative refueling, attendant can only be leaned on rule of thumb to refuel with feeling, so cannot know that oil mass is added or adds few.The present invention is blocked up by clean oil and user can be prevented to refuel the improper high temperature fault causing saggar or cause, solve problem improperly of refueling, the position that oil mass adds can be seen, it is the last line of defense ensureing reasonable volume read-out that clean oil of the present invention blocks up, to products such as the mechanical gear boxes not having assembly lube level sensor; In gearbox, the replacement cycle of lubricant oil generally carries out according to distance travelled or running time, in fact more accurately oil product is changed and be determined with the change of lube color, by structure observation of the present invention when lubricant oil becomes aterrimus by yellow light tone, and oil viscosity retrogradation, at this moment should more oil change in time, and the present invention does not need to open gearbox or drain the oil to determine, convenient and swift, structure of the present invention is simple, cost is low, is convenient to implement, reliable performance.
Further, clean oil covers and is inlaid with protective housing, utilizes protective housing to resist the impact of iron filings in oil and oil, protects transparent oil cap.
Further, the present invention is contained on the horizontal oil level peep hole of gear box casing, when oil is added to the horizontal position designed, oil will be blocked up body along oil and be flowed into by the concave edge of protecting cover in the gap of transparent oil cap and protective housing, at this moment just can see the position of oiling.
Further, the stifled body underpart of oil is provided with the screw thread be connected with the horizontal oil level peep hole of gear box casing, and screw thread and oil block up body and is connected plane place seal ring is housed, and sealed, avoid leakage of oil by seal ring.
