Description
Technical field
The present invention relates to a kind of gear.
Background technique
In modern age machine, gear transmission is modal a kind of mechanical transmission, and it transmits machine power and motion
A kind of form, having become indispensable transmission part at engineering goods middle gear, is engineering goods important foundation component.In automobile industry, the basic transmission element that gear is wanted as automobile primary, the quality of gear directly affects the noise of automobile, stationarity and working life.
Conventional gear is prepared from owing to usually adopting steel, need in preparation process to carry out machine shaping to the soft state of steel, need to carry out cure process to the flank of tooth after shaping to increase the service life to improve antiwear characteristic, the Surface hardening treatment such as usual employing Tempering and Quenching and nitriding carburizing, and such process sacrifices the precision of the flank of tooth for cost.
Conventional gear manufacturing mechanism input amount is large, and complex manufacturing, the manufacture cycle is long, and cost is higher.In order to the quality improving gear must drop into a large amount of precision gear process equipments, Gear Production equipment investment amount is large, and complex manufacturing, the Gear Production cycle is long, and cost is higher.
Summary of the invention
Complicated in order to solve the Gearmaking Technology existed in prior art, the problem that cost is high, the invention provides a kind of gear.
Technological scheme of the present invention is: a kind of gear, comprise gear, described gear comprises face portion and non-face portion, the center of described gear is provided with axis hole, the both sides end face of described gear is symmetrically arranged with round boss, described gear is also provided with equally distributed four through holes of ring-type, and described four through holes are positioned at inside the outside of described round boss and the gear ring of described gear, and face portion is made up of non-crystalline.
Preferably, the Vickers hardness of described non-crystalline is greater than 5GPa, and elastic strain limit is greater than 0.8%.
Preferably, non-crystalline chemical composition be: ZraCubAlcNidMe, wherein M represents the combination of a kind of element in Fe, Co, Mn, Cr, Ti, Ta, C and rare earth elements or multiple element, a, b, c, d, e are atomic percentage 40≤a≤60,10≤b≤40,10≤c≤17,5≤d≤15,0≤e≤5, and a+b+c+d+e=100.
Preferably, described non-face portion outer surface carries out copper plating treatment.
Beneficial effect of the present invention: the location that the present invention is met processing by four through holes and installed, effective, cost is low, and on the both sides end face of tooth body, symmetrically arranged round boss can increase the rotational strength of axis hole, whole gear is made to be easy to processing, and durable in use.Face portion adopts amorphous alloy, greatly reduces user cost, extends the working life of gear, and in addition, non-face portion adopts copper plating treatment, can reduce noise.
Accompanying drawing explanation
Fig. 1 is the structural representation of gear of the present invention;
In figure: 1 gear, 2 axis holes, 3 round boss, 4 through holes.
Embodiment
Mode of execution provided by the invention is described in further detail:
