摘要: A ball screw apparatus of a screw shaft circulating-type includes a nut having a first groove formed in an inner peripheral surface thereof, a screw shaft having a second groove formed in an outer peripheral surface thereof, and a plurality of rolling elements provided between the first and second grooves. A circulating groove is formed in the screw shaft so as to interconnect opposite ends in a spiral direction of the second groove of the screw shaft to form a closed-loop ball endless circulating passageway. Processing relief portions for preventing a processing tool of a rotary drive-type from interfering with the circulating groove when processing the second groove of the screw shaft by the processing tool are provided respectively at the opposite end portions in the spiral direction of the second groove of the screw shaft.

摘要: An internal-circulation-type ball screw includes a nut, a screw shaft, and two returning members. The nut has an internal-thread groove. The screw shaft passes through the nut and has an external-thread groove. The internally and external-thread grooves are aligned to form a helix channel. The screw shaft has a returning channel and two opposite receiving recesses. Each of the receiving recesses is radially communicated between the external-thread groove and the returning channel. The returning members are received in the receiving recesses of the screw shaft and each have a redirecting channel. The redirecting channel is connected between the helix channel and the returning channel, so that balls are allowed to circulate along the helix channel, the redirecting channel and the returning channel. Thereby, the internal-circulation-type ball screw provides good durability, reliability and smoothness in use.

摘要: A ball-worm transmission is provided which replaces the sliding friction of the classic worm mechanism with the rolling friction of spherical balls. The ball-worm transmission assembly includes a worm which defines a recirculation path, and a gear coupled to the worm via a plurality of spherical balls. The gear includes a plurality of teeth each having a thickness in a central plane of the gear and a lesser thickness towards both sides of the gear, so that a gap is defined between the teeth is larger towards both sides of the gear than in the central plane of the gear.

摘要: An axial displacement arrangement in the form of a ball screw and nut achieves a highly compact configuration by effecting ball recirculation entirely within the ball screw shaft. The ball recirculation portion of the ball screw shaft is axially short with respect to an elongated driven nut. As the nut is rotated, illustratively by an electric motor coupled thereto, the ball screw shaft is displaced axially along an axial support member. The axial support member has radially outward extending splines, and the ball recirculation portion of the ball screw shaft has radially inward extending splines, the inward and outward splines being arranged to face one another whereby a linear ball bearing region is formed. The linear ball bearing permits the ball recirculation arrangement and its associated actuation element to be displaced axially along the support element, but is precluded from rotating. A segmented ball recirculation end cap arrangement prevents the linear ball bearings from escaping axially from between the ball groove spline arrangement and the axial support element.
摘要翻译: 滚珠丝杠和螺母形式的轴向位移布置通过完全在滚珠丝杠轴内进行球再循环来实现非常紧凑的构造。 滚珠丝杠轴的球再循环部分相对于细长的被驱动的螺母轴向短。 当螺母旋转时,示例性地通过耦合到其上的电动马达,滚珠丝杠轴沿轴向支撑构件轴向移位。 轴向支撑构件具有径向向外延伸的花键,并且滚珠丝杠轴的球再循环部分具有径向向内延伸的花键,向内和向外花键被布置成彼此面对,由此形成线性球轴承区域。 线性球轴承允许球再循环装置及其相关联的致动元件沿支撑元件轴向移位,但不排除旋转。 分段球再循环端盖装置防止线性球轴承从球槽花键装置和轴向支撑元件之间轴向逸出。
