Arc gear drive design steps: 1) simplify the design: According to the transmission gear transmission power, input speed, transmission ratio and other conditions to determine center distance, modulus, and other key parameters. If the center distance modulus known, can skip this step. 2) calculate the geometric design: design and the basic parameters of gear, and geometry calculation. 3) Strength Check: The basic parameters established, the precise tooth contact strength and flexural strength tooth root check. 4) Check if the requirements are not satisfied with intensity, can be returned 切削，并严格控制装配误差。 单圆弧齿轮传动 小齿轮的凸齿工作齿廓在节圆以外，齿廓圆 心在节圆上；大齿轮的凹齿工作齿廓在节圆 内﹐齿廓圆心略偏於节圆以外(图 2 单圆弧 齿轮传动的嚙合情况 )。由於大齿轮的齿廓 圆弧半径 p2 略大於小齿轮的齿廓半径 p1﹐ 故当两齿廓转到 K 点﹐其公法线通过节点 c 时﹐齿便接触﹐旋即分离﹐但与它相邻的另 一端面的齿廓随即接触﹐即两轮齿 K1﹑K'1 ﹐K2﹑K'2﹑K3﹑K'3 ……各点依次沿嚙合线 接触。因此﹐圆弧齿轮任一端面上凹﹑凸齿 廓仅作瞬时嚙合。一对新圆弧齿轮在理论上 是瞬时点嚙合﹐故圆弧齿轮传动又常称为圆 弧点嚙合齿 轮传动。轮齿经过磨合后﹐实际 上齿廓能沿齿高有相当长的一段线接触。圆 弧齿轮传动的特点是﹕(1)综合曲率半径比 渐开线齿轮传动大很多﹐其接触强度比渐开 线齿轮传动约高 0.5～1.5 倍﹔(2)两轮齿沿 嚙合线方向的滚动速度很大﹐齿面间易於形 成油膜﹐传动效率较高﹐一般可达 0.99～ 0.995﹔(3)圆 弧齿轮沿齿高方向磨损均匀 ﹐且容易跑合﹔(4)圆弧齿轮无根切现象﹐ 故最小齿数可以少。但圆弧齿轮对中心距﹑ 切齿深度和螺旋角的误差敏感性很大﹐这三 项误 差对承载能力影响较大﹐故圆弧齿轮 对製造和安装精度要求较高。此外，单圆弧 齿轮轮齿弯曲强度较弱﹔切削同一模数的 大、小齿轮，需用两把不同的滚刀。 双圆弧齿轮传动 工作时，从一个端面看，先是主动轮齿的凹 部推动从动轮齿的凸部，离开后，再以它的 凸部推动对方的凹部，故双圆弧齿轮传动在 理论上同时有两个接触点，经跑合后，这种 传动实际上有两条接触线，因此可以实现多 对齿和多点嚙合。此外，由於其齿根厚度较 大，双圆弧齿轮传动不仅承载能力比单圆弧 齿轮传动约高 30％以上，而且传动较平稳， 振动和噪声较小，并且可用同一把滚刀加工 相配对的两个齿轮。因此。高速重载时，双 圆弧齿轮传动有取代单圆弧齿轮传动的趋 向。 Arc gear transmission characteristics: 1) pilot arc Gear meshing transmission, value applicable to helical gear, the gear can not be used directly. 2) relative radius of curvature than involute line, contact involute line intensity than high. 3) changes in the center distance than the sensitivity of the involute. Processing, Cutting depth requirements for higher radial displacement does not allow cutting and careful control of assembly error. Single arc Gear The small convex tooth gear tooth profile work outside in the circular section, tooth profile in the center of circle; large concave tooth gear tooth profile work in the Festival Circle, Center 略偏 in the tooth profile outside the circle section (Figure 2 single arc Gear Transmission meshing). Due to the large gear tooth profile arc radius p2 slightly larger than the small gear tooth profile radius p1, so when two K tooth profile to the point, its normal line through the node c, the tooth will contact immediately separated, but it is the other end o the tooth profile immediately contacted, or two teeth K1 ﹑ K'1, K2 ﹑ K'2 ﹑ K3 ﹑ K'3…… points followed along the line contact meshing. Therefore, the arc gear ﹑ concave surface of the convex side tooth profile only for instantaneous meshing. A new circular gear in meshing theory is instantaneous point, it Arc Gear also often called point arc meshing gear transmission. After running-gear tooth after tooth profile can actually high gear along with a rather long period of exposure. Arc Gear is characterized by: (1) comprehensive than the radius of curvature of involute gear transmission line much bigger than the strength of its contacts involute gear transmission line of about 0.5 to 1.5 times (2) two teeth meshing line along the direction rolling great speed, easy form of tooth surface oil film, transmission more efficient, usually ranging from 0.99 to 0.995 (3) arc high gear tooth direction along wear uniform, and easy running-in (4) arc cutting gear rootless the phenomenon, it could be the smallest number of teeth less. But from the arc of the Center ﹑ Gear Cutting helix angle and depth of the great sensitivity of error, the three errors on a greater impact on carrying capacity, so arc gear on the manufacture and installation of high accuracy requirements. In addition, single-arc Gear bending strength, relatively low modulus of the same cutting large and small gear, preparing two different hob. （ 返回 Back ） 同步带轮的型式 Pulley Types AS 型 Type BS 型 Type AF 型
