采用 Hägglunds 液压辊磨机传动。
概述
橡胶辊磨机为手动操作，因此轧辊的停止时间至关重要。
轧辊停止过程可按以下方法计算：
φ | Stop angle | ° |
n | Speed | rpm |
Jmachine | Moment of inertia machine | kg\u2022m2 |
Jmotor | Moment of inertia motor | kg\u2022m2 |
Ts | Specific torque | Nm/bar |
Δp | Pressure over motor | bar |
ts | Response time hydraulic valve | s |
φ = (π\u2022 n 2 \u2022(J machine + J motor )/(10 \u2022 Ts \u2022 Δp)) + 6 \u2022 n \u2022ts
示例：
CB400 在橡胶辊磨机中的典型应用
n = 15 rpm
J machine = 350 kgm 2
J motor = 18.3 kgm 2
φ = (π\u202215 2 \u2022(350+18.3)/(10\u2022400\u2022350))+6\u202215\u20220.15=13.7°

警告标志
本手册使用以下标志提示潜在危险，这些危险可能或必然造成人身伤害或重大财产损失。根据危险发生的可能性，以及可能造成的人身伤害或财产损失的严重程度，共分为三个等级。
Warning sign (warning triangle) | Draws attention to the hazard |
Signal word | Identifies the degree of hazard |
Type of risk | Specifies the type or source of the hazard |
Consequences | Describes the consequences of non-compliance |
Precautions | Specifies how the hazard can be prevented |
Warning sign, signal word | Meaning |
| | Indicates a dangerous situation which will cause death or severe personal injuries if not avoided. |
| | Indicates a dangerous situation which may cause death or severe personal injuries if not avoided. |
| | Indicates a dangerous situation which may cause minor or medium personal injuries if not avoided. |
| | Material damage: the product or its environment could be damaged. |
