  • Publication number: 20050259896
    Abstract: An innovative parabolic profiled rolling grooves for linear guide way is disclosed. Cross sectional profile of at least one of the ray-way and the slider grooves is configurated into a parabolic curve so as to avoid the balls to comprehensively contact the grooves and seriously increase the frictional loss. With the rolling grooves constructed as such, the mechanical durability and the loading ability can be definitely improved.

  • Publication number: 20040202390
    Abstract: The present invention relates to a ball connecting body for a ball screw or a linear guide-way, including spacers, guide linking members, and connecting members. The spacers are interposed between two adjacent balls, thereby preventing the two balls from hitting. The guide linking members are used for linking the two spacers, so that the ball may be maintained in a space formed by the guide linking members and the spacers. The connecting member connects two adjacent spacers. The total width of the connecting member in a direction of a connecting line of the two guide linking members is smaller than the total height of the connecting member in a direction vertical to the connecting line of the two guide linking members, so that the connecting member has an excellent bendable capability in the direction of the connecting line of the two guide linking members.

  • Patent number: 6585417
    Abstract: An interconnector for rolling balls in a ball screw or a linear guide way is composed of a spacer, a direction guiding member with two wings, and to linking chains. The adjacent rolling balls are isolated by the spacer so as to prevent mutual collision. The two adjacent spacers are connected with two elastically meandering linking chains able to be configurated in various forms so as to freely elongate and shrink. With this structure the guide way track is able to be formed into any shape which contributes to minimizing the size of apparatus and production cost, and allow the rolling ball to travel in a three dimensional course.

  • Patent number: 6220110
    Abstract: Disclosed herein is a leadscrew ball recirculation block with oil storing means wherein an cavity in the ball recirculation block which being not effectively used for circulating balls is utilized for storing lubrication oil. An oil exuding hole is provided to communicate with the oil stored cavity and a turning passage for balls so as to lubricate the moving balls. In order to prevent the lubrication oil remained at a standstill in a certain region in the cavity by its own gravity from failing to lubricate the balls, there is provided an oil containing element with a plurality of oil absorbing and distribution branches to lubricate the balls just passing by the turning passage. Furthermore, the ball recirculation block is formed of two pieces of plastic members bonded by supersonic wave bonding technique so as to achieve reduction of manufacturing cost and ensure perfect oil sealing effect of the ball recirculation block.
