- 適用范圍
- This standard covers the minimum requirements for general-purpose, enclosed single and multistage gear units incorporating parallel shaft spur, and helical gears for use in the petroleum, chemical, and gas industry services. General-purpose and extruder gears manufactured according to this standard are limited to pitch line velocities that do not exceed 60 m/s (12,000 ft/min). The requirements for parallel shaft helical gears applied to extruder services are included in Section 9 of this standard. The requirements for epicyclic gears driving equipment, such as electrical generators, centrifugal compressors, and pumps, are included in Section 10 of this standard. This standard does not apply to gears in special-purpose service, which are covered in API 613, to gears integral with other equipment, or gears with noninvolute tooth forms. NOTE General-purpose gears are applied in equipment trains that are usually spared, or are in noncritical service. Typical applications for which this standard is intended are cooling tower water pump systems, forced and induced draft fan systems, and other general-purpose equipment trains.
| 術(shù)語 | 描述 |
|---|---|
| 頂點 apex | 雙斜齒輪左右傾斜（螺旋）相遇的點所定義的平面。 |
| 頂點跳動 apex runout | 制造過程中產(chǎn)生的頂點平面的輕微偏差。 |
| 軸向浮動 axial float | 軸沿其旋轉(zhuǎn)軸線的自由運動，通常由推力軸承間隙或齒輪嚙合間隙或兩者的組合限制。 |
| 軸向分裂接頭 axially split joint | 主面與軸中心線平行的分裂接頭。 |
| 背隙 backlash | 在操作節(jié)徑上，齒槽寬度超過嚙合齒厚的量。 |
| 彎曲應(yīng)力數(shù) bending stress number | 對應(yīng)于齒根疲勞裂紋的可能性，如果過大，可能導(dǎo)致齒輪齒的失效。 |
| 布氏硬度 Brinell hardness | 材料抵抗壓痕的特性，不是基本的物理性質(zhì)。 |
