  • Circulation passage structure for a ball screw
    Patent number: 7628090
    Abstract: A circulation passage structure for a ball screw, the circulation passage structure is used to connect the helical groove and the circulation hole of the nut, so as to form a circulation path for a plurality of balls and spacers. Due to the spacers move in a manner of being clamped between two balls, the spacer inside the return path will be pushed to move inward. The degree of curvature of the inner guiding surface connected to the inner curve can be moderated by shifting outward the location of the center of the inner curve and increasing its radius of curvature. By such arrangement, the spacer will not contact the inner guiding surface when it is pushed to move inward, and the spacer can pass through the return passage easily without the problem of impacting the return passage.

  • Mechanism for suppressing grinding-cutting vibration
    Patent number: 7628681
    Abstract: A mechanism for suppressing grinding-cutting vibration comprises a C-shaped base, a fixed support seat, a clamp device and a vibration absorber. Based on vibration absorbing principle of the vibration theory, the clamp device is connected to the movable cutting machine, so as to move along with the cutting machine during the machining operation, and the clamp force applied to clamp the workpiece is adjustable. By such arrangements, the vibration energy produced at the time of cutting the workpiece can be transferred to the vibration absorber through the clamp device, and then a part of the vibration energy will be absorbed by the vibration absorber, thus achieving the objective of reducing vibration of the cut position.

  • Roller retainer
    Patent number: 7625120
    Abstract: A roller retainer mounted on a roller comprises a first guiding frame and a second guiding frame that are integrally connected with each other in a vertically staggered manner. The first guiding frame and the second guiding frame are located along the two diagonals of the roller respectively. The thickness of the first guiding frame and the second guiding frame is utilized to keep the space between the two non-loading surfaces of roller and a track. The roller retainer can further keep the space between each roller. Thereby, the roller retainer can prevent the rollers from contacting each other; the loading surfaces can still contact the track and the non-loading surfaces are prevented from colliding with and rubbing against the track, thus reducing the noise and ensuring the moving direction.
