Abstract
The utility model provides a kind of self-lubricating device of gear-box.All components of the lubricating arrangement are all placed on inside gear-box, are realized using the lubricating oil stored in the power and casing of gear-box itself and are lubricated the circulation of inner gear of the gear box and bearing.The course of work of this lubricating arrangement is: external impetus passes to gear shaft, while gear shaft drives working gear, drive the rotation of oil pump pinion gear, oil pump pinion gear drives operation of oil pump, oil pump is pumped into the lubricating oil in casing from pump inlet pipe, pressure oil is pumped out from oil pump outlet line, and the oil pumped out is lubricated the bearing and gear of needs.By adjusting the transmission ratio of gear shaft and oil pump pinion gear during this, oil pump pinion gear is set to reach required revolving speed, so that oil pump be made to reach ideal working condition.
Description
Technical field
The utility model relates to a kind of designs of the self-lubricating device of gear-box.The lubricating arrangement can not access additionally
In the case where power, the lubrication to gear-box itself is realized.
Background technique
For the vertical gearbox of axis perpendicular to the ground, because of the inclined shell of split bearing and gear present position in gear-box
There are problems for the lubrication of top, this split bearing and gear.Current various Lubrication Designs all Shortcomings: some is using full leaching
All gear and bearing are all immersed in oil by oily mode, this mode advantage be lubrication sufficiently, the disadvantage is that power loss it is big,
Gear-box fever is big, easy oil leakage；Some uses electric-motor pump forced feed lubrication, and advantage is that lubrication is reliable, power loss is few, gear-box hair
Heat is small, the disadvantage is that gear-box needs extra power, external pipeline easy oil leakage, unsightly.
Summary of the invention
In order to improve the shortcoming of above-mentioned vertical gearbox (or similar structures) lubricating system, the utility model provides one
The novel lubrication strategies of kind.All components of the lubricating arrangement are all placed on inside gear-box, utilize gear-box itself
The lubricating oil stored in power and casing, which is realized, lubricates the circulation of inner gear of the gear box and bearing.
A kind of self-lubricating device of gear-box described in the utility model, comprising: casing, lower section bearing, oil pump gear wheel,
Oil pump pinion gear, pump inlet pipe, oil pump bracket, oil pump, oil pump outlet line, gear shaft, top bearing, gear；
The oil pump bracket is fixed on casing；The oil pump is fixed on oil pump bracket；The oil pump oil inlet
Pipe one end is connected with the oil inlet of oil pump, and the other end is inserted into casing below the liquid level of lubricating oil；The oil pump outlet line one
End is connected with the oil outlet of oil pump, and the other end is directed at lubricant housings or is connected on separator；The oil pump pinion gear is fixed on
In the rotary shaft of oil pump, the oil pump gear wheel is fixed on gear shaft, and oil pump pinion gear is meshed with oil pump gear wheel；Institute
The gear shaft stated is meshed with gear；The gear shaft is placed on the bearing hole of casing by lower section bearing and top bearing
It is interior.
Further, suitable lubricating oil is added in gear-box casing, using submerged lubrication.
Further, the separator at required lubricant housings extra one when configure.
The utility model has the beneficial effects that power loss is small, gear-box fever is small, noise is small, does not need extra power, profit
Sliding reliable, pipeline be all set to the inside of gear box casing thus will not oil leak, do not influence gear-box appearance.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Wherein, 1- shell, the lower section 2- bearing, 3- gear, 4- oil pump pinion gear, 5- pump inlet pipe, 6- oil pump bracket, 7- oil
Bearing above pump, 8- oil pump outlet line, 9- gear shaft, 10-.
Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings of the specification.
Referring to attached drawing:
Reducer lubricating device described in the utility model include: casing 1, lower section bearing 2, gear 3, oil pump pinion gear 4,
Pump inlet pipe 5, oil pump bracket 6, oil pump 7, oil pump outlet line 8, gear shaft 9, top bearing 10.
The oil pump bracket 6 is fixed on casing 1；The oil pump 7 is fixed on oil pump bracket 6；The oil pump
5 one end of oil inlet pipe is connected with the oil inlet of oil pump 7, and the other end is inserted into casing 1 below the liquid level of lubricating oil；The oil pump goes out
8 one end of oil pipe is connected with the oil outlet of oil pump 7, other end alignment lubricant housings or is connected to separator (required lubricant housings is more
Configured when remaininging at one) on；The oil pump pinion gear 4 is fixed in the rotary shaft of oil pump 7, oil pump pinion gear 4 and oil pump canine tooth
Wheel 3 is meshed；The gear shaft 9 is meshed with oil pump pinion gear 4 and gear 3 simultaneously；The gear shaft 9 passes through lower section
Bearing 2 and top bearing 10 are placed in the bearing hole of casing 1.
The course of work of this lubricating arrangement is: external impetus passes to gear shaft 9, and gear shaft 9 works same with moving gear 3
When, drive oil pump pinion gear 4 to rotate, oil pump pinion gear 4 drives oil pump 7 to work, and oil pump 7 makes the lubricating oil in casing 1 from oil pump
Oil inlet pipe 8 is pumped into, and pressure oil is pumped out from oil pump outlet line 8, and the oil pumped out is lubricated the bearing and gear of needs.This mistake
By adjusting the transmission ratio of gear shaft 9 and oil pump pinion gear 4 in journey, oil pump pinion gear 4 is made to reach required revolving speed, to make
Oil pump reaches ideal working condition.
A kind of self-lubricating device lubrication of gear-box of the utility model is reliable, at low cost, can be in vertical gearbox or class
It is applied in mechanical device like structure.
The foregoing is merely the better embodiment of the utility model, the protection scope of the utility model is not with above-mentioned reality
The mode of applying is limited, as long as those of ordinary skill in the art's equivalent modification according to made by the utility model disclosure or change
Change, should be included in the scope of the protection described in the claims.
