圆弧齿轮传动类型：

1)圆弧圆柱齿轮分单圆弧齿轮和双圆弧齿轮。

2)单圆弧齿轮的接触线强度比同等条件下渐开线齿轮高，但弯曲强度比渐开线低。 3)圆弧齿轮主要采用软齿面或中硬齿面，采用硬齿面时一般用矮形齿。 圆弧齿轮传动设计步骤：

1) 简化设计：根据齿轮传动的传动功率、输入转速、传动比等条件，确定中心距、模数等主要参数。如果中心距、模数已知，可跳过这一步。

2) 几何设计计算：设计和计算齿轮的基本参数，并进行几何尺寸计算。

3) 强度校核：在基本参数确定后，进行精确的齿面接触强度和齿根弯曲强度校核。 4) 如果校核不满足强度要求，可以返回 圆弧齿轮传动的特点：

1) 圆弧齿轮传动试点啮合传动，值适用于斜齿轮，不能用于直齿轮。

2) 相对曲率半径比渐开线大，接触强度比渐开线高。

3) 对中心距变动的敏感性比渐开线大。加工时，对切齿深度要求较高，不允许径向变位

Arc Gear types:

1) single-cylinder gear circular arc gear and double arc gear.

2) single-arc gear contact line intensity ratio under the same conditions involute gear, but bending strength than involute line low.

3) arc gear used mainly in the soft or hardened tooth surface, which tends to be used when using Hardened dwarf gear.

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 ﹑ 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.

渐开线齿轮传动大很多﹐其接触强度比渐开 K3 ﹑ K'3…… points followed along the line contact meshing. Therefore, the arc gear ﹑
