Description

A kind of lubrication system for speed reducer
Technical field
The present invention relates to a kind of lubrication system for speed reducer, belong to field of mechanical technique.
Background technique
Speed reducer is a kind of mechanical fitting conventional in process of factory production, and speed reducer inside is the space of an opposing seal, and during operation, pressure can increase gradually, and temperature also rises gradually.On the other hand, need to lubricate by lubricant oil when the gear of speed reducer runs, and when temperature is elevated to 80-90 DEG C, can there is the phenomenon that blackening is oxidized even coking in lubricant oil.Lubricant oil is the rotten working life that can have a strong impact on gear due to high temperature, even directly causes gear failure, cause heavy losses to production.
The mode that closed-type cylindrical gearing speed reducer realizes lubrication mainly contains inner loop and outer loop two kinds.Inner loop, also known as splashing circulation, is take lubricant oil to gear and bearing formation lubrication from oil by the rotation of gear, is mainly applicable to the situation that gear linear velocity is less than or equal to 12-14 meter per second.When gear linear velocity is greater than 12-14 meter per second, using inner loop that lubricating oil temperature can be made to raise, can there is denaturalization phenomenon in lubricant oil; And some large-scale retarders use inner loop lubrication effect undesirable, now need to use outer loop.Outer loop is with oil pump to gear and bearing oil spout, and lubricant oil is not rotate by gear take on other gears and bearing but directly sprayed to the gear needing lubrication, and improve efficiency, secondly lubricant oil constantly sprays into from outside, can play cooling effect.For important retarder, also need to set up petrol station in outside, lubricant oil filters through petrol station, again lubricant oil is sent into lubricating point after cooling, and the lubricant oil after process could play lubrication better.But use outer loop lubricating system to have its shortcoming equally, first lubrication system is generally arranged on above speed reducer, accesses from top to bottom, when needing dismounting speed reducer, needs first dismounting lubrication system, and engineering is complicated, takes time and effort very much; Secondly, almost each gear accesses corresponding oil nozzle by oil pipe, and access multiple-tubing string one is waste lubricant oil, and two is that the too many oil pipe of access can cause sealing not exclusively, thus oozes out a large amount of greasy dirt, sealing joint place the aging of equipment; Again, after adopting outer loop, do not store lubricant oil in speed reducer, unnecessary lubricant oil flows away from oil outlet, if lubrication system breaks down suddenly, then speed reducer then can be subject to major injury, even equipment damage.Therefore seeking a kind of safety, clean, efficient lubrication system, is highly significant.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of lubrication system for speed reducer, and solve traditional speed reducer lubrication system high oil temperature and cause oil deterioration, equipment sealing is poor, greasy dirt easily oozes out, easily damaged speed reducer after breaking down, the problems such as equipment is installed complicated, maintenance difficulty.
The solution of above-mentioned technical problem have employed following technical measures: a kind of lubrication system for speed reducer, comprise gate valve, fuel reserve tank, gear pump, radiator, oil purifier, lower gate valve, pressure gauge, connect the transport pipe of native system all sites, an inverted u-shaped pipe is provided with between upper gate valve and speed reducer oil outlet, inverted u-shaped pipe top higher than low-gear bottom, upper gate valve connects fuel reserve tank, described fuel reserve tank, gear pump, radiator, oil purifier, lower gate valve is connected successively by transport pipe, all be arranged on below speed reducer, transport pipe end is equipped with oil nozzle, be connected to the side that speed reducer is equipped with high gear.
The present invention compares traditional speed reducer and has lot of advantages:
First the position of oil nozzle and the position of a complete set of lubrication system, is changed, tradition speed reducer lubrication system comprises oil nozzle and is all arranged on above speed reducer, when mechanical disorder or maintenance repair need dismounting, dismantles from high toward low, engineering work load is huge, wastes time and energy; Oil nozzle is arranged on speed reducer high gear side by the present invention, and a complete set of lubrication system is arranged on below speed reducer, only has oil nozzle and inverted u-shaped pipe to contact with speed reducer, when needing speed reducer dismounting, can not relate to lubrication system, only simple for speed reducer.Lubrication system is arranged on below speed reducer and also facilitates the lubricant oil flowed out from oil outlet to be directly back to fuel reserve tank in addition.
Secondly, decrease the quantity of oil nozzle, each gear arranged a corresponding oil nozzle in the past, find through production practices, low-gear rotating speed is very slow, does not need to lean on the mode of external lubrication to add lubricant oil, and the lubricating system of outer loop only needs for high gear.
Again, set up an inverted u-shaped pipe in speed reducer oil outlet position, after arranging inverted u-shaped pipe, the lubricant oil of speed reducer inside can not flow out from oil outlet at once, when oil mass save bit by bit oily level equal with inverted u-shaped pipe after, just can flow out according to law of connected vessels.Make the benefit keeping certain oil mass in speed reducer be inner loop and outer loop two kinds of modes can be combined like this, oil nozzle adopts the mode of outer loop, sprays the clean subzero oil processed, only for gear the most at a high speed; And adjust the height of inverted u-shaped pipe, make low-gear lowermost end can touch the lubricant oil stored in speed reducer, thus realize lubrication by splash lubrication mode.Like this for the lubricating system of different gear, more efficiently, clean.Make in speed reducer, to keep certain oil mass to also have another benefit to be break down suddenly when external lubrication system, when outer loop stops, the gear of speed reducer inside can also rely on splashing circulation to continue to realize inner loop a period of time, is unlikely to cause gear failure even equipment damage because of the fault of external lubrication system.
Finally, because have changed mounting type mounting point, this lubrication system can connect 1-6 platform speed reducer, supplies lubricant oil to 1-6 platform speed reducer simultaneously.
