1) foveolate center briquette
中凹形型煤
2) the flank concave
齿形中凹
1.
The gear shaving,which is widely applied to the manufacturing of the automobile, the tractor and mechine tools, is a traditional process of high-efficiency on the gear precision work, but the standard gear shaving tool when shaving can produce the flank concave, affecting the gear tooth profile processing precision and the gear transmission quality (high noise, low life).
剃齿是齿轮精加工的高效传统工艺,广泛应用于汽车、拖拉机和机床制造行业,但标准剃齿刀在剃齿时会产生齿形中凹,从而影响了齿轮齿形的加工精度和齿轮的传动质量(高噪声、低寿命)。
2.
It solves the flank concave problem.
针对齿轮剃齿加工中的齿形中凹问题 ,打破传统的剃齿刀修磨方法 ,利用齿面镀有金刚石的修磨轮在剃齿机上修磨剃齿刀 ,从而解决剃齿中凹问题。
3) Hollow Profile
中凹齿形
1.
Mechanism and Prevention Measures of Hollow Profile during Gear Grinding;
磨齿产生中凹齿形的机理与防止措施
4) birquette size
型煤形状
6) tooth-profile-concave-error
齿形中凹误差
1.
The tooth-profile-concave-error of the shaved gear is quantitatively explained and proved,which has important meaning for improving shaving precision and reducing noise.
运用啮合原理、微分几何和弹性力学等基础理论，对剃齿过程中的切削深度进行分析计算、定量解释并验证了被剃齿面产生的齿形中凹误差，对提高剃齿精度、降低齿轮传动噪音有着重要意义。
