Description
Technical field
The utility model relates to motor accessory technical field more particularly to a kind of Self-lubricating gear casees.
Background technique
The lubrication of gear-box is particularly significant, the reason of the gearbox failure in, lack of lubrication accounted for it is a greater part of, it is good
Lubrication can play enough protective effects to gear and bearing, and common gearbox lubrication mode has gear oil lubrication, semi-fluid
Body grease lubrication, solid lubricant lubricate several ways.Relatively good for sealing, revolving speed is higher, and load is big, and closed performance is good
Generally use gear oil lubrication, the mode of gear oil lubrication, common are forced feed lubrication and splash lubrication, for high gear
General selection splash lubrication, but for the gear-box of Multi-stage transmission, the oil droplet of splashing can only lubrication portion meshing gear, and
Meshing gear far from immersion oil gear then lubricates insufficient.
Utility model content
The problem of purpose of the utility model is to solve background techniques, and a kind of structure proposed it is simple,
It is capable of the Self-lubricating gear case of oneself lubrication.
To achieve the above object, the technical scheme adopted by the utility model is
A kind of Self-lubricating gear case is provided with loading driving tooth in the cabinet including the internal cabinet that gear set is arranged
The inner concave shape pump case of A is taken turns, is provided with the lateral fuel feed hole for leading to cabinets cavity, the inner cavity of the pump case on the side wall of the pump case
Bottom is provided with out oil groove, and the upper surface of described pump case is provided with the oil outlet being connected to oil groove out, connects profit on the oil outlet
The fueling injection equipment of sliding gear set.
Further improvement of the utility model is: the driven gear engaged with driving gear A is provided in the cabinet
A, with the driving gear B and the driven gear B that is engaged with driving gear B of driven gear A coaxial arrangement.
Further improvement of the utility model is: the fueling injection equipment includes going out to driving gear A conveying lubricating oil
The oil pipe I and flowline II that lubricating oil is conveyed to driving gear B.
Further improvement of the utility model is: the bottom of the pump case be provided with lead to lateral fuel feed hole it is vertical into
Oilhole, the transverse direction fuel feed hole correspond to the root portion position of driving gear A.
By adopting the above-described technical solution, the technological progress that the utility model obtains is:
Self-lubricating gear case inner pinion gear A only increases pump case as pump leaf, and driving gear A and pump case form half and wrap
Formula centrifugal pump is enclosed, structure is simple, and it is at low cost, not only save the expense for purchasing grease pump, and the lubrication effect of gear, bearing
Fruit is also fine.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of pump case；
Fig. 3 is diagrammatic cross-section of the utility model at fuel feed hole.
Specific embodiment
Wherein: 1, cabinet 2, pump case 3, driving gear A 4, flowline I 5, driven gear A 6, driving gear B 7, from
Moving gear B 8, flowline II 9, oil outlet 10, lateral fuel feed hole 11, go out oil groove 12, vertical fuel feed hole.
The utility model is described in further details with reference to the accompanying drawings and examples:
A kind of Self-lubricating gear case, as shown in Figure 1, Figure 2, Figure 3 shows, the cabinet 1 including internal setting gear set, in cabinet 1
Be provided with inner concave shape pump case 2, driving gear A3 be set in pump case 2, driving gear A3 is driven by input shaft, and by input shaft and
Bearing is erected on cabinet 1, and the driven gear A5 engaged with driving gear A3, same with driven gear A5 is additionally provided in cabinet 1
The driving gear B6 of the axis setting and driven gear B7 engaged with driving gear B6.
It is provided with lateral fuel feed hole 10 on the side wall of pump case 2, the inner cavity of pump case 2 is connected on the inside of lateral fuel feed hole 10, it is corresponding
The root portion position of driving gear A3, the bottom of pump case 2 are provided with the vertical fuel feed hole 12 for being connected to lateral fuel feed hole 10, vertically
The other end of fuel feed hole 12 leads to the inner cavity of cabinet 1.
The intracavity bottom of pump case 2 is provided with out oil groove 11, and the upper surface of pump case 2 is provided with and oil groove 11 is connected to out oil outlet
9, the fueling injection equipment of oilgear group is connected on oil outlet 9.
Fueling injection equipment includes conveying lubricating oil to the flowline I4 of driving gear A3 conveying lubricating oil and to driving gear B6
Flowline II8.
Self-lubricating gear case is got rid of the lubricating oil in pump case 2 to oil groove 11 out by running at high speed for driving gear A3, and
Flowline I4 and flowline II8 are sprayed to by oil outlet 9, provides lubrication by flowline I4 and flowline II8 for meshing gear.
