Description
Technical field
A kind of lubricant level fuel-flow control structure is the utility model is related to, in particular for flying in rail traffic gear box
The lubricant level fuel-flow control structure splashed in lubricating system, belongs to mechanical field.
Background technology
Rail traffic gear box typically all uses splash lubrication, as shown in figure 1, gear box lubricating oil is stored in gear-box bottom
Portion, working gear are immersed in lubricating oil, and splashing Lubricant on Gear case inner body by working gear rotation is lubricated.
When gearbox high-speed is run, gear stirs oily aggravation, the increase of gear-box power consumption, temperature rise, then needs to reduce oil level
To improve；And during low speed operation, gear stirs oil slowly, and lubricating oil fuel feeding again can be insufficient, then needs raising oil level to improve.Passing
In system design, the oil level of gear box lubricating oil can not dynamically be changed, and to ensure that gear-box reliably lubricates, often be taken
High oil level design, but gear-box power consumption and temperature rise cannot be controlled reasonably.In addition, because rail traffic gear box bottom is empty
Between limit, when being driven for large speed ratio gear, because canine tooth wheel diameter is big, be close to bottom half, cause bottom half trapped fuel empty
Between it is narrow and small, have enough lubricating oil to make gear-box, oil level is set will be higher（Working gear Immersion Depth is deeper）, gear
Case power consumption and the phenomenon of temperature rise are more prominent.For above-mentioned technology existing for current track transport gear case lubrication System Design
Contradiction, have become technical barrier in the urgent need to address in the industry.
Utility model content
The purpose of this utility model is：For skill present in traditional rail traffic gear box design and practical application
Art contradiction, rail traffic gear box provide a kind of new lubricant level fuel-flow control structure being used in splash-lubricating system.
What the purpose of this utility model was realized in：A kind of lubricant level oil mass being used in splash-lubricating system is adjusted
Nodule structure, including working gear, the work oil sump of housing bottom being locally bathed in lubricating oil, it is characterised in that：Housing bottom
Portion is provided with front and rear oil level adjustable plate, and front and rear oil level adjustable plate is in eight word arrangement, and housing bottom is divided into work oil sump and position
Storage oil sump before and after the oil sump that works；The bottom of oil level adjustable plate is provided with the connected entrance linked up work oil sump and store oil sump,
Top is provided with overfall, and the minimum operating fluid level of initial lubricating oil is higher than edge on the connected entrance of oil level adjustable plate, initial lubricating oil
Highest operating fluid level be less than oil level adjustable plate overfall.
The utility model has the advantage of：Because housing bottom is provided with front and rear oil level adjustable plate, front and rear oil level adjustable plate edge
The cylindrical arrangement of working gear, in eight word arrangement, can be adjusted with the particular location of conjunction gear roller box portion requiring lubrication during design
Oil level adjustable plate subtended angle, orientation determine to get rid of the direction of oil.As a result of front and rear oil level adjustable plate, therefore no matter working gear revolves
Turn how direction changes, the governor motion that the utility model is related to can normal regulating lubricating oil liquid level.
Due to housing bottom is divided into work oil sump and the storage oil sump before and after work oil sump, and oil level adjustable plate
Bottom be provided with link up work oil sump and store oil sump connected entrance, by setting the size of connected entrance, can set storage oil
To the size of work oil sump supply lubricating oil oil mass, final purpose is to be to realize that the oil level of work oil sump can turn with gear in pond
Speed rising and decline, be specifically realized in：When working gear is run in low speed, gear stirs oily slow, front and rear storage
Oil sump can be work oil sump make-up oil in time by connected entrance, maintain the oil level of low speed operation, ensure low speed lubrication；When
Working gear stirs speed oil and accelerated in high-speed cruising, and the speed oil that enters of connected entrance is basically unchanged, work oil sump lubricating oil
The speed oil that stirs of the gear of the relatively high speed operation of recharge rate will be insufficient, and the oil level for the oil sump that works can then decline, you can realize
The oil level of work oil sump declines with the rising of gear rotational speed, and oily power consumption and gear-box temperature rise are stirred so as to reduce gear-box.
Because top is provided with overfall, oil level adjustable plate runs at high speed when working gear, the lubricant level for the oil sump that works
Meeting continuous decrease, front and rear storage oil sump can not meet lubrication needs by connected entrance, because storage sump liquid level rising is bright
It is aobvious, it can be now work oil sump make-up oil by overfall, that is, ensure the minimum oil level under existing high-speed cruising.
Due to having distinguished work oil sump and storage oil sump, it is easy to lubricating oil to be deposited because of bubble caused by gear agitation
Separated out in oil storage pool, improve the performance of lubricating oil.
As a result of front and rear oil level adjustable plate, based on the regulation mechanism of oil level adjustable plate, therefore no matter working gear revolves
Turn how direction changes, the governor motion that the utility model is related to can normal regulating lubricating oil liquid level.The utility model is also
Can solve the contradiction of big speed ratio lower tooth roller box lubricating oil deficiency.Preferably resolve rail traffic gear box design and reality
The technical contradiction present in.
The advantages of the utility model, also resides in：Because oil level adjustable plate is located at housing bottom, added equivalent to for housing
One group of gusset, the mechanical strength of housing can be strengthened.Meanwhile of the present utility model simple in construction, reliable, Maintenance free,
The efficiency of gear-box can be significantly improved, reduce the operating temperature of lubricating oil.
