Abstract
The utility model discloses an oil spout lubricating structure of a speed changer second shaft, wherein the axial center of a biaxial bearing is designed into an oil inlet pore passage, an oil outlet pore passage is arranged on the axial center vertical direction, the oil inlet pore passage is communicated with the oil outlet pore passage, and lubricating oil can enter from the oil inlet pore passage, and is ejected out from the oil outlet pore passage for lubricating the bearing. The speed changer biaxial oil spout lubricating structure has simple structure, realizes complete, even and sustaining lubrication to the biaxial bearing on the premise of not adding external components through optimizing the inner structure, and greatly improves the safety and the service life when a speed changer second shaft works.
Description
Technical field
The utility model relates to the bearing lubrication structure field, two oil jet lubrication structures of a kind of specifically speed changer.
Background technique
Gear on two of the current automotive transmissions and the gear on the jack shaft are normal engagement, and endoporus is equipped with the needle bearing sky and is enclosed within on two, for lubricated these needle bearings, all are provided with lubrication oil circulation (turnover) hole on two shaftgears.Enter the lubricants capacity deficiency of bore, lubricating condition is bad, or fricative heat can not in time take away by lubricated oil, and the needle roller axle will the expanded by heating distortion, and reduction in strength finally causes needle bearing to lose efficacy.Therefore, above-mentioned its lubrication of method of passing through lubricated two upper bearing (metal)s of oilhole on two shaftgears is very limited, and bearing very easily weares and teares, and the heat energy that high-speed gear running simultaneously the produces bearing of very easily ablating again makes the phenomenon of two lockings happen occasionally.What is more, and two lockings will cause gearbox stuck, and traffic accident very easily takes place, and bring very big threat to traffic safety.
The model utility content
The purpose of this utility model is to provide a kind of speed changer two oil jet lubrication structures, it can lubricate speed changer two axle bearings fully, evenly and constantly, avoid the generation of the phenomenon of two lockings, Security when greatly improving two work of speed changer, the working life that the prolongation speed changer is two.
Concrete technological scheme of the present utility model is: two oil jet lubrication structures of a kind of speed changer, it is characterized in that the axle center of two axle bearings is set to the oil-feed duct, and and set out the oilhole road on the Vertical direction of axle center, the oil-feed duct communicates with fuel-displaced duct.During work, lubricant oil enters the axle center from the oil-feed duct, is ejected into bearing surface by each fuel-displaced duct again, thereby lubricates two axle bearings fully, equably, can realize the continuous lubrication to two axle bearings easily.
Preferably, above-mentioned oil-feed duct and fuel-displaced duct are cylindrical, and the diameter in oil-feed duct is greater than the diameter in fuel-displaced duct.
Two oil jet lubrication structures of speed changer of the present utility model have following beneficial effect: simple in structure, production and processing is convenient; Lubrication effect to two axle bearings is abundant, even; The safety coefficient height, long service life.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the utility model structural representation.
Among the figure:
1, oil-feed duct; 2, fuel-displaced duct.
Embodiment
As shown in Figure 1, two oil jet lubrication structures of speed changer described in the utility model, the axle center of its two axle bearing is columniform oil-feed duct 1, be provided with columniform fuel-displaced duct 2 with the axle center Vertical direction, oil-feed duct 1 communicates with fuel-displaced duct 2, and the diameter in oil-feed duct 1 is greater than the diameter in fuel-displaced duct 2.
During work, lubricant oil enters the axle center from oil-feed duct 1, is ejected into bearing surface by each fuel-displaced duct 2 again, thereby lubricates two axle bearings fully, equably, thereby realizes the continuous lubrication to two axle bearings easily.
Two oil jet lubrication structures of speed changer of the present utility model, simple in structure, by optimization to internal structure, under the prerequisite that does not increase external member, realized abundant, even and lasting lubricated of two axle bearings, greatly improved two of speed changers when work Security and prolonged its working life.
Claims (2)
1, two oil jet lubrication structures of a kind of speed changer is characterized in that the axle center of two axle bearings is set to the oil-feed duct, and set out the oilhole road on the Vertical direction of axle center, and the oil-feed duct communicates with fuel-displaced duct.
2, two oil jet lubrication structures of speed changer according to claim 1, it is cylindrical to it is characterized in that oil-feed duct and fuel-displaced duct are, and the diameter in oil-feed duct is greater than the diameter in fuel-displaced duct.
