Description
Technical field
The utility model relates to the component technical field of motor, especially relates to a kind of ignition timing gear.
Background technique
Motor is a kind of power generating apparatus, and its effect is mechanical energy by other forms of Conversion of Energy.Ignition timing gear is the common gearing parts of engine interior.The heavier-weight of prior art ignition timing gear, gear vibrates comparatively large in the course of the work, causes during work and produces a large amount of noises, and the wearing and tearing between gear can be made for a long time comparatively large, and loosening appears in transmission, thus has influence on the normal work of gear.In addition, due to wearing and tearing, timing gear easily misplace, thus have had influence on timing gear life-span and work.
Model utility content
The utility model solves larger problem of wearing and tearing between said gear heavier-weight and gear, provide a kind of ignition timing gear, this gear structure is simple, lightweight, gear is corrosion-resistant and wear and tear little between gear, fills that operational vibration is within the engine little, noise is low, transmission efficiency is high, long service life.
The required technical problem solved of the utility model can be achieved through the following technical solutions:
A kind of ignition timing gear, comprise the wheel disc of antirust treatment, described sheave surface has a carburized case; The dish edge of described wheel disc is uniform-distribution with the gear teeth, has a teeth groove between adjacent two gear teeth, and described teeth groove bottom land both sides are provided with arc angling; The front and back card of described wheel disc offers circular groove, in described circular groove, offers duplicate removal hole; The center of described wheel disc offers central through bore, and the inwall of central through bore has corrosion-resistant coating.
The thickness of described carburized case is 0.5-0.8mm.
Described duplicate removal hole is through hole.
Described duplicate removal hole is distributed in around central through bore radially.
Described duplicate removal hole is 6.
Described wheel disc offers a positioning hole.
Have rotating shaft from central through bore through and with central through bore interference fit.
The front and back card edge of described wheel disc offers duplicate removal groove.
The utility model beneficial effect is: a kind of ignition timing gear, and structure is simple, be easy to realize, and by the design of duplicate removal hole and duplicate removal groove, effectively can alleviate the weight of gear, make working gear load little, vibrate little, stabilization of speed; The corrosion-resistant coating of wheel disc antirust treatment, central through bore inwall, can improve the ability of gear rust-proofing and corrosion; The arc angling design of the gear teeth, can improve gear antiwear property, considerably increase the working life of ignition timing gear; Fill that operational vibration is within the engine little, noise is low, transmission efficiency is high, long service life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is the utility model gear structure schematic diagram.
Fig. 2 is the utility model gear generalized section.
Fig. 3 is the utility model gear adjacent teeth close-up schematic view.
Fig. 4 is the utility model gear adjacent teeth B-B generalized section.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
During concrete enforcement, a kind of ignition timing gear, composition graphs 1-Fig. 4, comprises wheel disc 1, the gear teeth 2, teeth groove 3, arc angling 4, circular groove 5, duplicate removal hole 6, central through bore 7, corrosion-resistant coating 8, duplicate removal groove 9, positioning hole 10.
Ignition timing gear comprises the wheel disc 1 crossed through antirust treatment.Carbonitriding process is carried out on wheel disc 1 surface, and sheave surface forms a carburized case, and the thickness of carburized case is 0.5-0.8mm.The dish edge of wheel disc 1 is dispersed with the gear teeth 2 equably, and have teeth groove 3 between two gear teeth be connected, the bottom land both sides of teeth groove 3 are provided with arc angling 4.Gear tooth is designed with the friction that arc angling can reduce between engaging gear, reduces the wearing and tearing between gear, increases the life-span of ignition timing gear.
The front and back card of wheel disc 1 offers circular groove 5, offers duplicate removal hole 6 and positioning hole 10 in circular groove 5.The through hole that the front and back card that duplicate removal hole 6 and positioning hole 10 are all through wheel disc is connected with circular groove.Wheel disc distributes six duplicate removal holes 6, adjacent two duplicate removal holes difference 60 degree.The design in circular groove 5 and duplicate removal hole 6 is the weight in order to alleviate gear, and make it vibrate in transmission operation process little, rotating speed is steady.Positioning hole 10 provides timing gear and installs location, prevents from installing between gear misplacing.
The Center of wheel disc 1 becomes central through bore 7, have rotating shaft from central through bore 7 through and with central through bore interference fit.The inwall of central through bore 7 is provided with corrosion-resistant coating 8, and corrosion-resistant coating can improve gear anti-corrosion capacity, considerably increases the working life of ignition timing gear.The front and back card edge of wheel disc 1 offers duplicate removal groove 9 as shown in Figure 2, and the design of duplicate removal groove can alleviate the weight of gear equally, and gear is vibrated in transmission operation process little, rotating speed is steady.
Ignition timing gear, structure is simple, be easy to realize, and by the design of duplicate removal hole and duplicate removal groove, effectively can alleviate the weight of gear, make working gear load little, vibrate little, stabilization of speed; The corrosion-resistant coating of wheel disc antirust treatment, central through bore inwall, can improve the ability of gear rust-proofing and corrosion; The arc angling design of the gear teeth, can improve gear antiwear property, considerably increase the working life of ignition timing gear.
The utility model ignition timing accuracy of gear reach more than 7 grades, surface zero defect also carries out antirust treatment, design of gears is reasonable, and the accuracy of gear of processing is high, fills that operational vibration is within the engine little, noise is low, compact structure, transmission efficiency are high, long service life, interchangeability are good.
