Description
Technical field
The utility model relates to a kind of wear-resistant gear.
Background technique
Gear is as a kind of common power transmission mode, be widely used in production, every field in life, when general gear coordinates driving mechanism to carry out transmission of power, generally to occupy larger space, because power province consumption is larger in transmission process, transmission efficiency is caused not to be often very high, and the torsional moment that can carry is also less, and general Gear center installation shaft, the outside of axle is provided with framework, but this gear axial trough is generally round structure, such structure easily produces centrifugal force, in addition, existing gear can not add lubricant oil between rotating shaft and draw-in groove, heat can be produced in the process of motion, cause gear wear, working life shortens, simultaneously due in the production of gear and the process of installation, because the external toothing of gear and interior axis hole are all have strict matching requirements, if so process other parts using it as fixed position, can affect to machining accuracy, and size produces after certain deviation and is difficult to repair, cause unnecessary scrapping.
Summary of the invention
It is good that the technical problems to be solved in the utility model is to provide a kind of wear resistance, long service life, ensuring smooth transmission, and transmission efficiency is high, carrying moment is large, process and wear-resistant gear is easily located in installation.
For solving the problem, the utility model adopts following technological scheme:
A kind of wear-resistant gear, comprise gear body, the middle part of described gear body is provided with the positioning hole of annular spread, described gear body is provided with the wheel flank of tooth, feeding bank and axial trough, described feeding bank is between the wheel flank of tooth and axial trough, described feeding bank is provided with several, and all run through face of gear and axial trough, described take turns the flank of tooth is provided with equally distributedly ringwise revolve type tooth, described face of gear is provided with the filler opening corresponding with feeding bank, and all revolving the recess between type tooth, described axial trough is the axial trough of square structure, the inner side surface of described axial trough is provided with equally distributed rake tooth.
As preferably, described in revolve type tooth and be provided with more than ten, revolve type tooth and utilize the structural characteristics of revolving type to increase tightness between two teeth, torsion during rotation between wheel tooth also increases.
As preferably, described filler opening is the notch of feeding bank, can flow to feeding bank toward filler opening lube oil injection.
As preferably, described gear body is provided with three feeding banks, described feeding bank distributes ringwise, oil can be delivered between rake tooth uniformly.
As preferably, the middle part of described gear body is provided with three positioning holes of annular spread, can install gear, ensure the processing of gear and the precision of installation as the datum hole installing location.
The beneficial effects of the utility model are: owing to being provided with feeding bank and filler opening, can, toward gear axial trough conveying lubricant oil, make the wear resistance of gear good, long service life; Owing to being provided with square axial trough, lower the centrifugal force that when rotating, gear produces, ensuring smooth transmission; Revolve type tooth owing to being provided with, transmission efficiency is high, carrying moment is large.By the location that three positioning holes meet processing and install, effective, cost is low.The inner side surface of described axial trough is provided with equally distributed rake tooth, and can fix more firm, transmission is more accurate.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of wear-resistant gear of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of wear-resistant gear, comprise gear body 1, the middle part of described gear body 1 is provided with the positioning hole 7 of annular spread, positioning hole 7 not only can alleviate the weight of this province of gear, and middle axial trough 5 can be processed as the datum hole of locating and machining, as the datum hole installing location, gear can be installed, ensure the processing of gear and the precision of installation.Circular positioning hole 7 balance is better, can not have influence on the rotation of gear.Described gear body 1 is provided with the wheel flank of tooth 2, feeding bank 6 and axial trough 5, described feeding bank 6 is between the wheel flank of tooth 2 and axial trough 5, described feeding bank 6 is provided with several, and all run through face of gear 2 and axial trough 5, when using this gear, to filler opening 4 lube oil injection, lubricant oil can flow in axial trough 5 by feeding bank 6 always, thus lubrication axial trough 5 and rotating shaft, reduce wearing and tearing, described take turns the flank of tooth 2 is provided with equally distributedly ringwise revolve type tooth 3, revolving type tooth 3 utilizes the structural characteristics of revolving type to increase tightness between two teeth, torsion during rotation between wheel tooth also increases, described face of gear 2 is provided with the filler opening 4 corresponding with feeding bank 6, and all revolving the recess between type tooth 3, described axial trough 5 is the axial trough of square structure, axial trough 5 is firmly connected with rotating shaft according to square structure, not easily skid.The inner side surface of described axial trough is provided with equally distributed rake tooth 8, and can fix more firm, transmission is more accurate.
The described type tooth 3 that revolves is provided with more than ten, and more teeth more have torsion.
Described filler opening 4 is the notch of feeding bank 6, can flow to feeding bank 6 toward filler opening 4 lube oil injection.Described gear body 1 is provided with three feeding banks 6, described feeding bank 6 distributes ringwise, oil can be delivered between rake tooth 8 uniformly.Three positioning holes, 7, three positioning holes 7 that the middle part of described gear body 1 is provided with annular spread can be located more accurate.
When using this wear-resistant gear, by three positioning holes 7, gear is arranged in rotating shaft, rotating shaft is provided with the tooth coordinated with rake tooth, locate more firm, good a certain amount of lubricant oil is injected again toward filler opening 4, lubricant oil arrives between rake tooth by feeding bank 6, makes the wear resistance of gear good, and working life increases.
The beneficial effects of the utility model are: owing to being provided with feeding bank and filler opening, can, toward gear axial trough conveying lubricant oil, make the wear resistance of gear good, long service life; Owing to being provided with square axial trough, lower the centrifugal force that when rotating, gear produces, ensuring smooth transmission; Revolve type tooth owing to being provided with, transmission efficiency is high, carrying moment is large.By the location that three positioning holes meet processing and install, effective, cost is low.The inner side surface of described axial trough is provided with equally distributed rake tooth, and can fix more firm, transmission is more accurate.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection domain of this practicality and be as the criterion.
