    • A brake that can particularly be applied to a linear motor has a gripping member that can move axially within the housing of the brake. The gripping member is lightly urged against the rotor of the linear motor such that movement of the rotor in one direction causes the gripping member to grip the rotor more strongly and movement of the rotor in the other direction causes the gripping member to grip the rotor less strongly. The gripping member can be completely disengaged from the rotor and can be held in the disengaged position by an electromagnet. Upon the cessation of power to the electromagnet (for example if there is a power interruption), the gripping member automatically moves in a direction that allows it to grip the rotor more strongly and thus provides a fail-safe brake. In a preferred embodiment, the brake can be moved into its deactivated position using the power only from the linear motor. There is also disclosed a novel use for a helical tension spring wound in a loop, the spring acting as both a linear bearing and as a means for providing a radially inward force. Methods of disengaging and applying a brake are also disclosed.
    • 特别适用于线性电动机的制动器具有可在制动器的壳体内轴向移动的夹持构件。 夹紧构件被轻轻地推靠在线性电动机的转子上,使得转子在一个方向上的运动使得夹持构件更牢固地夹持转子,并且转子沿另一方向的运动使得夹持构件更少地夹住转子 强烈。 夹持构件可以完全脱离转子并且可以通过电磁体保持在脱离位置。 在停止对电磁铁的电力(例如,如果存在电力中断)时,夹持构件自动地沿着允许其更强地握住转子的方向移动,从而提供故障保护制动器。 在优选实施例中,仅使用来自线性电动机的功率,制动器可以移动到其停用位置。 还公开了一种用于缠绕在环中的螺旋拉伸弹簧的新颖用途,弹簧用作线性轴承和用作提供径向向内的力的装置。 还公开了分离和施加制动器的方法。

A tape seal (112) of the channel (82) extends through a slot (180) formed in the body (120) so that the calipers (152) moveably mounted to the body (120) are located within a hollow interior of the channel (82). The calipers (152) include cylindrical carriers (154) slideably received in cross bores (130) in the body (120) and are biased to a disengaged position by a spring (164) sandwiched between a snap ring (162) in the cross bore (130) and the carrier (152). A diametric groove (156) is formed on the inner axial end of the carrier (154) and slideably receives a side (140) of an actuator element (138) which extends in a non-axial direction. The actuator element (138) is moveably mounted in an axial through bore (122) by first and second supports (142, 143) secured to the axial ends and including an elastomeric seal (144) to compliantly suspend the actuator element (138) in the through bore (122). The actuator element (138) is moved in a first axial direction by a spring (146) and in the opposite axial direction by fluid pressure in a fluid chamber.

    • The spindle (6) is axially movable with respect or a support member (8) by an electric linear motor (29). The operating head (5) is fitted with a pneumatic cylinder (53) collaborating with a piston (54) engaged with a stop part (61) carried by the support member (8) in order to balance the weight of the spindle (6), enabling a reduction of the power required by the linear motor (29). The operating head (5) is also fitted with a second pneumatic cylinder (86) collaborating with a corresponding piston (84), which carries a locking element (81) able to engage a rack (79) carried by the support member (8). The piston (84) is biased by a spring (96) engaged with the rack (79), both in the event of the non-balancing of the weight of the spindle (6) as well as the non-excitation of the linear motor (29), to automatically block the vertical shifting of the operating head (5). The spindle (6) is cylindrically shaped and has a ring-shaped shoulder (14), that allows easy assembly on a body (11) fitted with a pair of axially spaced rings (13), in which the spindle (6) is inserted so as to rest the shoulder (14) against the upper ring (13). Each ring (13) has a notch (18) and a tightening screw (21) of the notch (18) to angularly lock the spindle (6) on the body (11).

    • A straight sliding bearing and a straight sliding table according to the present invention are formed so as to increase the frictional resistance occurring when a slide block (1) is moved slidingly on a track base (2), by pressing the side surfaces of rollers (4a) by a braking plate (5) which is adapted to be moved in accordance with the pressure of a fluid, and suppressing the rolling of the rollers (4), (4a) by utilizing the frictional force generated by this roller pressing operation. Since a predetermined level of rigidity can be obtained in the axial direction as well of the track base (2) by arbitrarily increasing and decreasing the sliding resistance, the sliding bearing and sliding table enable a high precision machined product to be obtained when these sliding devices are used in a mechanical apparatus, such as a machine tool.
