Abstract
The utility model discloses a gear lubrication mechanism of a ball mill. The gear lubrication mechanism comprises a ball mill control cabinet, and a big bevel wheel transmission mechanism, a small bevel wheel transmission mechanism and a motor driving mechanism are installed in the control cabinet. The gear lubrication mechanism is characterized in that an injection port is arranged on the control cabinet corresponding to the big bevel wheel transmission mechanism and the small bevel wheel transmission mechanism, a nozzle is arranged on the injection port, and the nozzle faces to a gear face of a big gear wheel. A liquid collecting groove is arranged below the big gear wheel in the control cabinet, and the liquid collecting groove is connected with a waste liquor recovery groove through a pipeline. The gear lubrication mechanism is reasonable in structure and design, oil can be adhered to the gear face for a long time and be not easy to fly out through structural design of injection angles of the nozzle and the liquid collecting groove, simultaneously lubricating grease recycle can be carried out, waste of resources is reduced, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of ball mill operation lubricating structure, relates in particular to a kind of ball mill gear lubrication mechanism.
Background technology
The running of ball mill by synchronous motor through a pair of large and small helical gear since during the ball mill running on each gear teeth of gear near the pressure the pitch circle all very big because the gear surface after Overheating Treatment can't bear the dry friction of so big pressure; So except that the selection of lubricating oil, lubricating system (as: spray angle of nozzle) also can influence lubricant effect, existing nozzle mostly is that the face of gear to pinion carries out oil spout fat; Think and reduce grease amount when can guarantee to lubricate like this; But because the rotating ratio of pinion is very fast, therefore be difficult to stick to face of gear for a long time, be easy to receive action of centrifugal force to fly out; Thereby make grease not play lubricant effect or lubricant effect is poor; And pinion below grease liquid bath also useless, having caused the waste of grease, production cost is high.
The utility model content
The purpose of the utility model is in order to remedy the deficiency of prior art; A kind of ball mill gear lubrication mechanism is provided; Solved existing ball mill when lubricated the position of nozzle unreasonable, its grease that ejects is difficult to stick to for a long time on the pinion face, flown out by action of centrifugal force; Cause the waste of grease, problems such as production cost height.
The utility model is realized through following technical scheme:
A kind of ball mill gear lubrication mechanism; Include the ball mill control cabinet; Large and small spiral gear drive mechanism and motor-driven mechanism are installed in the said control cabinet; It is characterized in that: the corresponding control cabinet of said large and small spiral gear drive mechanism is provided with jet, and said jet is provided with nozzle, and said nozzle is towards the wheel flank of tooth of gear wheel; The gear wheel below is provided with collecting tank in the described control cabinet, and said collecting tank arrives the waste liquid accumulator tank through pipeline.
Described nozzle supplies fat by two line lubrication system, and said two line lubrication system includes and supplies fat system and air supply system, and the charging mouth of pipe of said nozzle is communicated to respectively through pipeline and supplies fat system and air supply system.
Its principle is:
According to gear-driven principle, two teeth are equivalent to do pure rolling on pitch circle, so the linear velocity of large and small gear equates on pitch circle, and the formula of centrifugal force:
If: the quality that is attached on the grease of the flank of tooth does
, the pitch radius of pinion does
, the linear velocity at pitch circle place does
1The pitch radius of gear wheel does
, the linear velocity at pitch circle place does
2,
The centrifugal force that lubricating grease is attached on little gear ring and the bull gear is respectively
,
By on can know:
1=
2,
So:
=
1 2/
1-1 gets according to formula:
Can know that by formula 1-2 size and two tooth radius that lubricating grease is attached on centrifugal force on the large and small gear ring are inversely proportional to, because the ratio of the pitch radius of large and small gear ring
≈ 10, ∴
The centrifugal force that when lubricating oil sprays to bull gear, receives is to receive 1/10 of centrifugal force when spraying to little gear ring.
Therefore lubricant grease is injected on the canine tooth wheel face, grease can stick on the face of gear for a long time, and centrifugal force is little; Be not easy to fly out, through the structural design of collecting tank, can be lubricated the recycling of grease simultaneously; Reduce the waste of resource, reduced production cost.
The utility model has the advantages that:
The utility model reasonable in design, through the structural design to nozzle spray angle and collecting tank, grease can stick on the face of gear for a long time; Be not easy to fly out; Can be lubricated simultaneously the recycling of grease, reduce the waste of resource, reduce production cost.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing; A kind of ball mill gear lubrication mechanism; Include ball mill control cabinet 1, large and small helical gear 2,3 transmission mechanism and motor-driven mechanism are installed in the control cabinet 1, the control cabinet 1 that large and small helical gear 2,3 transmission mechanisms are corresponding is provided with jet 4; Jet 4 is provided with nozzle 5, and nozzle 5 is towards the wheel flank of tooth of gear wheel 2; Gear wheel 2 belows are provided with collecting tank 6 in the control cabinet 1, and collecting tank 6 arrives waste liquid accumulator tank 7 through pipeline.Described nozzle 5 supplies fat by two line lubrication system, and two line lubrication system includes and supplies fat system 8 and air supply system 9, and the charging mouth of pipe of nozzle 5 is communicated to respectively through pipeline and supplies fat system 8 and air supply system 9.
