Abstract
A motion guide apparatus includes a cylindrical member having a peripheral protrusion formed between two outer peripheral recesses, a housing engaged onto the cylindrical member and having a peripheral swelling formed between two peripheral depressions, a number of bearing members engaged between the cylindrical member and the housing, and two actuating ring members each having a number of orifices for engaging with the bearing members and each having an inner side portion directed toward the peripheral protrusion and the peripheral swelling, and each having an operating device extended into the gap that is formed between the peripheral protrusion and the peripheral swelling for wiping the lubricating oil.
Claims11
A motion guide apparatus comprising:
- a cylindrical member including an outer peripheral portion, and including two peripheral recesses formed in said outer peripheral portion of said cylindrical member and spaced from each other for forming and defining a peripheral protrusion between said peripheral recesses of said cylindrical member,
- a cylindrical housing including a bore formed therein for receiving and engaging with said cylindrical member, and including two peripheral depressions formed in said housing and spaced from each other for forming and defining a peripheral swelling between said peripheral depressions of said housing and for aligning with said peripheral protrusion of said cylindrical member and for forming and defining a peripheral gap between said peripheral protrusion and said peripheral swelling, said housing including an entrance for supplying a lubricating oil into said peripheral gap that is formed between said peripheral protrusion of said cylindrical member and said peripheral swelling of said housing,
- a plurality of bearing members received and engaged in said peripheral recesses of said cylindrical member and said peripheral depressions of said housing and engaged with said peripheral protrusion and said peripheral swelling for guiding said housing to rotate relative to said cylindrical member, and
- two actuating ring members each including a plurality of orifices formed therein for receiving and engaging with said bearing members respectively and for allowing said bearing members and said actuating ring members to be received and engaged between said housing and said cylindrical member, said actuating ring members each including an inner side portion directed toward said peripheral protrusion and said peripheral swelling, and each including an operating device provided in said inner side portion of said actuating ring member and extended into said peripheral gap that is formed between said peripheral protrusion and said peripheral swelling for engaging with and for guiding the lubricating oil to flow toward said actuating ring members and said bearing members.
