Technical field
The utility model relates to the component technical field of air compressor, especially relates to a kind of air compressor gear.
Background technique
Air compressor is the main body in compressed air source unit, and it is the device mechanical energy of prime mover being converted to gas pressure energy, is compressed-air actuated pressure generator.Gear is the inner common gearing parts of air compressor.The gear weight of existing air compressor mounted inside is heavier, wear and tear between gear larger, vibrate larger in the course of the work, cause during work and produce a large amount of noises, work long hours in process, coordinating between gear with live axle there will be loosening, make live axle duty ratio larger, vibration is large, and rotary speed unstabilization is fixed, thus affects the normal work of air compressor.Due to wearing and tearing, have influence on air compressor gear life.
Model utility content
The utility model solves larger problem of wearing and tearing between said gear heavier-weight, gear, a kind of air compressor gear is provided, this gear structure is simple, gear weight is light, 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 air compressor 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; The front card of described wheel disc offers circular trough, in circular trough, offers duplicate removal hole; The front-end face of described wheel disc offers splined hole, and the ear end face center of wheel disc offers cone shape hole, and the inwall of described cone shape hole has corrosion-resistant coating, and the side of cone shape hole has rectangle keyway.
The thickness of described carburized case is 0.5-0.8mm.
Described wheel disc is connected between two gear teeth teeth groove.
Described teeth groove bottom land or both sides are provided with arc angling.
Described duplicate removal hole is through hole.
Described cone shape hole is through hole.
Described splined hole is through hole.
Described wheel disc card edge offers duplicate removal groove.
The utility model beneficial effect is: a kind of air compressor gear, and structure is simple, be easy to realize, and by the design of duplicate removal hole and circular trough, effectively can alleviate the weight of gear, make air compressor gear load in transmission process little, vibrate little, stabilization of speed; The corrosion-resistant coating of wheel disc antirust treatment, cone shape 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 air compressor 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.
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 air compressor gear, composition graphs 1 and Fig. 2, comprise wheel disc 1, the gear teeth 2, teeth groove 3, arc angling 4, circular trough 5, duplicate removal hole 6, splined hole 7, cone shape hole 8, corrosion-resistant coating 9, rectangle keyway 10, duplicate removal groove 11.
Air compressor 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 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 of gear, increases the life-span of air compressor gear.
The front card of wheel disc 1 offers circular trough 5.Duplicate removal hole 6 and splined hole 7 is offered, the through hole that the front card that duplicate removal hole 6 and splined hole 7 are all through wheel disc is connected with circular trough in circular trough 5.Wheel disc distributes multiple duplicate removal hole 6 and splined hole 7.The design in circular trough 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.Splined hole is convenient to gear and is connected with transmission shaft, guarantee to vibrate in transmission little, rotating speed is steady.
The tapered hole 8 of ear end face Center of wheel disc 1, have rotating shaft from cone shape hole 8 through and with cone shape hole 8 interference fit.The side of cone shape hole 8 offers rectangle keyway 10, the installation that rectangle keyway provides gear and live axle is located, and prevents between gear and live axle and misplaces, and makes the assembling between gear and live axle more firm, reliable, dismantle also very easy, ensure that the normal work of air compressor.The inwall of cone shape hole 8 is provided with corrosion-resistant coating 9, and corrosion-resistant coating can improve gear anti-corrosion capacity, considerably increases the working life of air compressor gear, thus ensure that the normal work of air compressor.
The front and back card edge of wheel disc 1 offers duplicate removal groove 11, 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.Also facilitate assembling and the dismounting of air compressor gear and live axle simultaneously, also can be used as the impregnating fluid spout of live axle.
The utility model air compressor gear, structure is simple, be easy to realize, and by the design of duplicate removal hole and circular trough, effectively can alleviate the weight of gear, make air compressor gear load in transmission process little, vibrate little, stabilization of speed; The corrosion-resistant coating of wheel disc antirust treatment, cone shape 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 air compressor gear; Be contained in that operational vibration in air compressor is little, noise is low, compact structure, transmission efficiency are high, long service life, interchangeability are good.
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.
