Fred气动执行器的设计特点
Fred气动执行器结构
Construction of Fred Pneumatic Actuator |
 挤压铝质(ASTM6005)缸体，内表面细磨精加工，内部和外部均采用高级防腐技术，气缸摩擦系数小，使用寿命长，抗腐蚀性能强。
双活塞齿轮齿条式设计，结构紧凑、安装位置对称、改变输出轴转向方便，使用寿命长、动作迅速。
活塞齿条背面装有复合轴承及导向环，动作精确、摩擦系数小、使用寿命延长。
组合式预负荷镀层弹簧，工作寿命长。
高精度齿轮和齿条，啮合间隙小、精度高，输出功率大。
不锈钢紧固件，安全美观，抗腐蚀性强。
采用国际规范尺寸：输出轴槽、螺孔；顶部安装孔尺寸符合NAMUR标准；气源接口尺寸符合NAMUR标准；底部安装孔尺寸符合ISO5211、DIN3337标准, 方便安装电磁阀、限位开关等附件。
Designing features of Fred-RD Series Pneumatic Actuator
Extruded aluminum ASTM6005 body with both internal and external corrosion protection having honed cylinder surface for longer life and low coefficient of friction.
Dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle life and fast operation, reverse rotation can be accomplished in the field by simply inverting the pistons.
Multiple bearings and guides on racks and pistons, low friction, high cycle life and prevent shaft blowout.
Modular preloaded spring cartridge design, with coated spring for simple versatile range, greater safely and corrosion resistance, longer cycle life.
Fully machined teeth on piston and pinion for accurate low backlash rack and pinion engagement, maximum efficiency.
Stainless steel fasteners for long term corrosion resistance
Full conformance to the latest specifications: ISO5211, DIN 3337 and Namur or product interchangeability and easy mounting of solenoids, limit switches and other accessories
