Title
(EN) Pneumatic rotary tools
(ZH) 气动旋转工具
Abstract
(EN) A pneumatic rotary tool has a housing formed primarily from plastic so that the weight and price of the tool are substantially reduced. The air motor is formed for economic assembly while permitting greater structural stability should the housing deflect under an impact. The tool includes a torque selector which controls the amount of pressurized air allowed to enter the air motor, thereby controlling the torque output of the motor. The user may adjust the torque selector to a number of set positions which correspond to discrete torque values. The tool additionally incorporates early and late stage exhaust ports, so that backpressure within the air motor does not slow motor rotation or decrease tool power.

本发明公开了一种气动旋转工具,其具有一个基本上是用塑料制成的外壳,从而能显著地减小该工具的重量和造价。气动马达被制成经济性很好的组件,同时还保证了在外壳受到冲击作用而产生偏斜时,马达具有较大的结构稳定性。该工具包括一个扭矩选择器,其控制进入到气动马达中的压缩空气的量,由此控制了马达的输出扭矩。使用者可在一组设定档位之间调节扭矩选择器,其中的设定档位对应于几个不连续的扭矩值。工具还包括一个初期排气端口和一个后期排气端口,从而气动马达内的背压就不会减慢马达的转速或减小工具的功率。
