Description
Technical field
The utility model relates to gear technique field, especially a kind of Novel herring bone cylindrical gears being widely used in heavy machinery transmission system.
Background technique
Gear refers to, and wheel rim has tooth can engage the mechanical component transmitting motion and power continuously, can realize the conversion between rotation motion and straight line motion.Traditional gear structure is complicated, and manufacturing process is loaded down with trivial details, is not easy to installation and removal, transferring power performance is not high, in the operation process of high-speed and high-intensity, understand severe friction thus produce heat and cause wearing and tearing, thus allowing to shorten the working life of gear, and likely mechanical accident occurring.Conventional gears can produce vibration and noise when high speed operation simultaneously, and also can produce larger axial force, efficiency is low, function singleness, cannot meet diversified production requirement.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of Novel herring bone cylindrical gears.
The utility model solves the technological scheme that its technical problem adopts: a kind of Novel herring bone cylindrical gears, there is cylindric gear, described gear center offers mounting hole, mounting hole inwall offers multiple spline, described gear outer wall vertical is provided with teeth, teeth comprise left-handed teeth and dextrorotation teeth, offer tool withdrawal groove between left-handed teeth and dextrorotation teeth, left-handed teeth and right-hand teeth mandibular joint symmetrical in tool withdrawal groove; Be provided with V-arrangement oil groove between described adjacent two teeth, gear is provided with the annular oil groove be connected with each V-arrangement oil groove, and the distance between described adjacent two teeth is 6-10mm; Protecting jacket is provided with in described mounting hole.
Further, described gear is provided with multiple positioning hole, and positioning hole is positioned at spline periphery and distributes around the mounting hole center of circle.
Further, described annular oil groove and mounting hole are that concentric distributes.
Further, the distance between described adjacent two teeth is 10mm.
Further, described protecting jacket is nylon protecting jacket, and protecting jacket is replaceable.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, left-handed teeth and right-hand teeth mandibular joint symmetrical in tool withdrawal groove, have that bearing capacity is high, stable drive and an advantage such as thrust load is little, be applicable to heavy machinery transmission system; V-arrangement oil groove and annular oil groove match, and improve the greasy property of herringbone gear; Be provided with removable protecting jacket, improve the wear-resisting property of herringbone gear, when only changing protecting jacket after protecting jacket breakage, cost is low, effectively extends the working life of herringbone gear.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
1. gear, 2. mounting hole, 3. spline in figure, 4. left-handed teeth, 5. dextrorotation teeth, 6. positioning hole, 7. tool withdrawal groove, 8.V shape oil groove, 9. annular oil groove, 10. protecting jacket.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Novel herring bone cylindrical gears as depicted in figs. 1 and 2, there is cylindric gear 1, gear 1 center offers mounting hole 2, mounting hole 2 inwall offers eight splines 3, gear 1 outer wall vertical is provided with teeth, teeth comprise left-handed teeth 4 and dextrorotation teeth 5, offer tool withdrawal groove 7 between left-handed teeth 4 and dextrorotation teeth 5, left-handed teeth 4 and dextrorotation teeth 5 symmetrical about tool withdrawal groove 7; Be provided with V-arrangement oil groove 8 between adjacent two teeth, gear 1 is provided with the annular oil groove 9 be connected with each V-arrangement oil groove 8, and the distance between adjacent two teeth is 10mm; Protecting jacket 10 is provided with in mounting hole 2.
Gear 1 is provided with four positioning holes 6, and positioning hole 6 is positioned at spline 3 periphery and distributes around mounting hole 2 center of circle; Annular oil groove 9 with mounting hole 2 for concentric distributes; Protecting jacket 10 is nylon protecting jacket.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
