20130294713 | MOVABLE MEMBER FOR LINEAR SLIDE ASSEMBLY - A movable member of a linear slide assembly includes a slide member having two legs to mount the slide member to a rail. Two covers are respectively connected to two ends of the slide member. A track is formed between the legs of the slide member and the rail. Rolling members are installed in the circulation path of the slide assembly and drive the movable member along the rail back and forth. Two reinforcement plates are respectively connected to outside of the two covers and each reinforcement plate has a side plate and two bent extensions which are fixed to the legs of the slide member. The bent extensions each have an engaging portion which is engaged with the protrusion on the slide member. The engaging portions bear axial force applied to the rolling members to secure the connection between the covers and the slide member. | 11-07-2013 |
20130305852 | ROLLER MAINTAINING CHAIN AND METHOD FOR MAKING ROLLER MAINTAINING CHAIN AND LINEAR MOVEMENT DEVICE - A roller maintaining chain includes an elongate strip having multiple holes separated by separation blocks. Each hole has a hole face perpendicular to the elongate strip. Each separation block has a top separation block and a bottom separation block. Each of the top and bottom separation blocks has an accommodating surface which has a flat surface and an inclined stop surface. A part of each accommodating surface is perpendicular to planes on the axial direction of the elongate strip. The flat surfaces of the top and bottom separation blocks are smoothly connected to each other. The inclined stop surfaces are inclined toward the top direction of the holes to maintain the rollers in the holes. The method for making the roller maintaining chain uses a left mold and a right mold, the two molds are split inclinedly and laterally to obtain the roller maintaining chain. | 11-21-2013 |
20130315515 | CIRCULATION MAINTAINING DEVICE FOR LINEAR SLIDE ASSEMBLY - A circulation maintaining device for a linear slide assembly includes two top boards, four half mediate plates, two third half tubes, two bottom boards, and two end caps. Each of the above mentioned parts is manufactured integrally by way of injection molding and needs only one set of molds. These parts are connected to the slider symmetrically. Each of the half mediate tubes provides a second half tube and a half mediate plate. The second half tubes are inserted into the top holes and the bottom holes from two ends of the slider. The two half maintaining plates each have stops and recessed areas in longitudinal direction thereof so as to form restriction in transverse direction. The half maintaining plats each have ribs which are engaged with the grooves in the slider to provide positioning effect in a vertical direction. | 11-28-2013 |
20140060996 | CHAIN FOR ROLLING ELEMENTS - A chain for rolling elements includes a carrier belt having first and second side strip on two sides thereof, and multiple holes are defined in the carrier belt and located between the first and second side strips. Each hole has a first opening end and a second opening end. Multiple retainers are connected to the carrier belt and located alternatively with respect to the holes. Multiple first ribs are connected between the first side strip and the retainer. Multiple second ribs are connected between the second side strip and the retainer. Each of the first and second side strips has a thickness T | 03-06-2014 |
20140152124 | COIL UNIT AND COIL ASSEMBLY FOR IRON-LESS LINEAR MOTOR - A coil unit and coil assembly for iron-less liar motor and the coil unit includes two vertical function sides and two axial non-function sides. The multiple units are alternatively connected to each other by inserting the vertical function side of one coil unit into the hollow portion of the adjacent coil unit so as to form a coil assembly. The width of the vertical function side is D1 and the distance between two respective insides of the two vertical function sides is D2. D2=m×D1+ΔL, wherein m representing the number of the vertical function sides of other coil units received in the vertical direction of the hollow portion. The ΔL is the width of the gap which receives a separation plate between the two adjacent vertical function sides to increase the efficiency of dissipating heat or insulation when current passes through the coil assembly. | 06-05-2014 |
20140161379 | ENDLESS CIRCULATION PATH FOR LINEAR RAIL - An endless circulation path for a linear rail includes a loaded path, an unloaded path and two direction change paths which are connected between the loaded path and the unloaded path. Each of the unloaded path, the direction change paths and the loaded path has top and bottom grooves. A first line is connected between top and bottom grooves of the unloaded path. A second line is connected between the top and bottom grooves of each of the direction change paths. A slope of the second line, starting from the intersection between the direction change path and the unloaded path to the intersection between the direction change path and the loaded path, is gradually inclined relative to the first line. A third line is connected between the top and bottom groove of the loaded path. The third line is inclined relative to the first line. | 06-12-2014 |
20140177986 | ROLLER RETAINING CHAIN - A roller retaining chain includes a carrier belt extending along a longitudinal direction and multiple holes are defined through the carrier belt so as to respectively receive a roller therein. A retainer is located between any two adjacent holes and each of the retainers includes a first part and a bottom part. The first/second part has a first/second face facing the hole. Each of the first and second faces has a guide member and each guide member has a guide face which is perpendicular to the longitudinal direction. The two respective guide faces are located on the same plane. Each of the guide faces has an inclined stop face extending therefrom so as to retain the roller in the hole. Each roller is in contact with the two guide faces to prevent from being tilt. | 06-26-2014 |
20140199133 | BOLT-HOLE CAP FOR BOLT HOLE IN LINEAR RAIL - A bolt-hole cap for sealing the bolt hole of a rail includes a top face and a bottom face from which multiple protrusions extend. Each protrusion extends radially from inner portion toward outer portion of the bolt-hole cap. Each protrusion has two side faces and an end face connected between the two side faces. The end face has a first width. When the bolt-hole cap is inserted into a bolt hole and the top face of the bolt-hole cap is in flush with the top face of the rail, the end face of each of the protrusions contacts the bolt in the bolt hole. The protrusions are plastically deformed toward the side faces and the end face has a second width which is wider than the first width, so that the bolt-hole cap has sufficient strength to keep the top thereof flushing the top of the rail. | 07-17-2014 |
20140376838 | SLIDER ASSEMBLY - A slider assembly configured to move on a slide rail along an axial direction without limitation in distance is provided to solve the problems of the middle retaining members of a conventional circulation maintaining device, e.g., insufficient connection rigidity and inconvenience in manufacture and assembly. The positioning portion of a middle retaining member and the positioning portion of the protrusion of a slider are connected in a direction perpendicular to both the axial direction and a transverse direction in which the protrusion projects, thereby connecting the middle retaining member and the protrusion securely and evenly along their entire lengths. The middle retaining member and the protrusion also feature ease of manufacture and assembly. | 12-25-2014 |
