Description
Technical field
The utility model relates to the component technical field of motor, especially relates to a kind of camshaft idle gear.
Background technique
Camshaft idle gear is the common gearing parts of engine interior, can be assemblied in other machinery such as motor, water pump.Existing camshaft idle gear is solid construction, gear weight is heavier, wear and tear between gear comparatively large, cause it to vibrate in the course of the work comparatively large, produce a large amount of noises, work long hours in process, coordinating between gear with live axle there will be loosening, and make live axle duty ratio comparatively large, vibration is large, rotary speed unstabilization is fixed, thus has influence on the normal work of other machinery such as motor, water pump.Due in the environment through being everlasting inclement condition such as motor, water pump, therefore require higher for its corrosion resistance.
Model utility content
The utility model solves above-mentioned camshaft idle gear heavier-weight, coordinating between gear with live axle there will be loosening problem, provide a kind of camshaft idle gear, this gear structure is simple, gear weight is light, 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 camshaft idle gear, comprise the wheel disc of antirust treatment, described sheave surface is provided with carburized case; Described wheel disc dish edge is uniform-distribution with the gear teeth, and be connected between two gear teeth and have teeth groove, tooth groove root is provided with arc angling; Described wheel disc card offers circular groove; Described wheel disc is provided with axial hole, and the inwall of described axial hole has corrosion-resistant coating, and described axial hole and sheave surface are provided with fluting.
The thickness of described carburized case is 0.5-0.8mm.
Described sheave surface offers multiple aperture.
Have rotating shaft from axial hole by and with axial hole interference fit.
Described arc angling is tooth groove root ipsilateral chamfering.
The utility model beneficial effect is: a kind of camshaft idle gear, and structure is simple, be easy to realize, and by the design of circular groove, effectively can alleviate the weight of gear, make camshaft idle gear load in transmission process little, vibrate little, stabilization of speed; The corrosion-resistant coating of wheel disc antirust treatment, axial hole inwall, can improve the ability of gear rust-proofing and corrosion; Be furnished with jump ring in fluting, gear and live axle are coordinated by jump ring and closely there will not be loosening phenomenon, considerably increase the working life of camshaft idle gear.
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.
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 camshaft idle gear, composition graphs 1 and Fig. 2, comprise wheel disc 1, the gear teeth 2, teeth groove 3, axial hole 4, corrosion-resistant coating 5, aperture 6, fluting 7, circular groove 8.
Camshaft idle gear comprises the wheel disc 1 crossed through antirust treatment, and wheel disc 1 is made up of steel for carburizing material.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 is dispersed with the gear teeth 2 equably, and have teeth groove 3 between two gear teeth be connected, the tooth groove root ipsilateral of teeth groove 3 is arc angling.Gear tooth is designed with the friction that arc angling can reduce between engaging gear, reduces the wearing and tearing of gear, increases the life-span of camshaft idle gear.
The Center of wheel disc becomes axial hole 4, have rotating shaft from axial hole through and with axial hole interference fit.The inwall of axial hole is provided with corrosion-resistant coating 5, and corrosion-resistant coating can improve gear anti-corrosion capacity, considerably increases the working life of camshaft idle gear.Wheel disc can have one or more aperture 6, regulate wheel disc weight, make it in rotation process, there will not be swing.Axial hole and sheave surface are provided with fluting 7, slot as jump-ring slot, are furnished with jump ring in jump-ring slot, and gear and live axle are coordinated by jump ring and closely there will not be loosening phenomenon, make live axle load smaller, vibrate little, stabilization of speed.
The front and back card of wheel disc offers circular groove 8.The design of circular groove is the weight in order to alleviate gear, and make it vibrate in transmission operation process little, rotating speed is steady.
The utility model camshaft idle gear, structure is simple, be easy to realize, and by the design of circular groove, effectively can alleviate the weight of gear, make camshaft idle gear load in transmission process little, vibrate little, stabilization of speed; The corrosion-resistant coating of wheel disc antirust treatment, axial hole 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 camshaft idle gear; Be furnished with jump ring in fluting, gear and live axle are coordinated by jump ring and closely there will not be loosening phenomenon.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
