摘要： A dental handpiece is disclosed including a turbine construction creating a radial in flow of air onto the impeller blades about the whole circumference of the turbine, This generates additional torque and avoids asymmetrical thrust on the impeller wheel. A pair of axially spaced air bearings support the turbine. Air supply to the bearings is controlled in such a way that the air bearings are floated before drive air is supplied to the turbine and after drive air to the turbine has been shut off. This ensures that the air bearings are always operational irrespective of the operational state of the turbine. The handpiece has an improved ergonomic shape, especially the shape and configuration of the front or drive head, which provides additional tooth clearance and a better field of view. An angled swivel connection to the umbilical cord is provided which reduces physical strain on the dentist's wrist. A self adjusting lock and key type torque connection between the dental burr and the chuck is provided which accommodates both conventional burrs and the burr of the lock and key arrangement. An auto stop arrangement for the turbine is disclosed which prevents a vacuum build-up during run-down of the turbine. The specific construction of the auto stop valve in accordance with the invention closes both the drive and exhaust air conduits.
摘要翻译：公开了一种牙科手机，其包括在涡轮机的整个圆周上产生径向空气流入叶轮叶片的涡轮机结构，这产生额外的扭矩并避免了叶轮上的非对称推力。一对轴向隔开的空气轴承支撑涡轮机。以这样一种方式控制对轴承的空气供应，使空气轴承在驱动空气供应到涡轮机之前以及在关闭涡轮机的驱动空气之后浮起。这确保空气轴承总是可操作的，而与涡轮机的操作状态无关。手机具有改进的符合人体工程学的形状，特别是前部或驱动头的形状和结构，其提供额外的齿隙和更好的视野。提供与脐带的倾斜旋转连接，减少牙医手腕上的物理应变。提供牙科毛刺和卡盘之间的自调节锁和键型扭矩连接，其容纳常规毛刺和锁和钥匙布置的毛刺。公开了一种用于涡轮机的自动停止装置，其防止在涡轮机的下降期间的真空积聚。根据本发明的自动截止阀的具体结构关闭了驱动和排气管道。

摘要： The invention relates to an improved dental tool drive arrangement for a handpiece with a drive head, the tool drive arrangement permitting length adjustment of the tool in the drive head by concentrically supporting the tool in the drive head at any position from a fully inserted position to a maximum retracted position. The tool drive arrangement preferably includes a tool and a rotatable tool supporting element for concentrically supporting the tool from the fully inserted to the maximum retracted position, the tool preferably including a maximum retraction indicator for indicating to a user when the tool has been retracted to the maximum retraction position. This provides a significant advantage over the prior art by allowing a user to adjust the exposed length of a rotatable tool, preferably a dental bur, without exceeding safe operating limits. The invention also relates to an improved drive spindle which allows depth adjustment of a tool in a dental handpiece while maintaining efficient torque transfer and concentricity during high speed rotation.
摘要翻译：本发明涉及一种用于具有驱动头的手持件的改进的牙科工具驱动装置，该工具驱动装置允许通过在从完全插入位置到完全插入位置的任何位置同心地支撑工具在驱动头中的工具的长度调节最大缩回位置。工具驱动装置优选地包括工具和可旋转的工具支撑元件，用于将工具从完全插入到最大缩回位置同心地支撑，该工具优选地包括最大缩回指示器，用于当工具已经缩回到最大缩回位置。这通过允许使用者在不超出安全操作限制的情况下调节可旋转刀具（优选牙科钻头）的暴露长度来提供比现有技术更大的优点。本发明还涉及一种改进的驱动主轴，其允许在牙科手机中的工具的深度调节，同时在高速旋转期间保持有效的扭矩传递和同心度。
