Abstract
A planetary reduction mechanism includes a ring member and a planetary rotary member internally meshing with the internal gear, and a pin. The pin extends through the planetary rotary member for preventing orbital motion or rotation of the planetary rotary member, or for taking out an orbital motion component or a rotational component thereof. A continuous groove is formed on an outer circumference of the pin.
Claims9
A planetary reduction mechanism comprising:
- a planetary rotary member;
- a ring member with which the planetary rotary member internally meshes or contacts;
- and
- a pin extending through the planetary rotary member for preventing orbital motion or rotation of the planetary rotary member, or for taking out an orbital motion component or a rotational component thereof;
- wherein
- a continuous groove is formed on an outer circumference of the pin.
A pin structure of a planetary reduction mechanism, the planetary reduction mechanism having a carrier, wherein
- the pin is integrated with the carrier as a portion of the carrier, and
- a continuous groove is formed on an outer circumference of the pin.
A method for manufacturing a pin of a planetary reduction mechanism, the planetary reduction mechanism comprising a planetary rotary member, a ring member with which the planetary rotary member internally meshes or contacts, and the pin extending through the planetary rotary member for preventing orbital motion or rotation of the planetary rotary member, or for taking out an orbital motion component or a rotational component thereof, the method including steps of:
- manufacturing a original of the pin, and
- forming a continuous groove on an outer circumference of the original.
