Abstract
A plasticizing device for plasticizing material that includes a drive motor having a rotating drive shaft member; a decelerator configured to reduce speed of rotation of the drive motor and to output rotation; and a screw having a groove and rotating via the decelerator, wherein the decelerator includes a first bearing section that receives a drive force from the drive shaft member, a first covering section that surrounds an outer periphery of the first bearing section and that contacts and covers the first bearing section, and a first gear that surrounds an outer periphery of the first covering section and that rotates in contact with the first covering section and the first covering section includes a first holding section that holds lubricant.
Claims8
A plasticizing device for plasticizing a material, the plasticizing device comprising:
- a drive motor having a rotating drive shaft member;
- a decelerator configured to reduce speed of rotation of the drive motor and to output rotation;
- and
- a screw having a groove and rotating via the decelerator, wherein
- the decelerator includes:
- a first bearing section that receives a drive force from the drive shaft member;
- a first covering section that surrounds an outer periphery of the first bearing section and that contacts and covers the first bearing section;
- and
- a first gear that surrounds an outer periphery of the first covering section and that rotates in contact with the first covering section, and
- the first covering section includes a first holding section that holds lubricant.
A decelerator that reduces and outputs rotation of a drive motor that has a rotating drive shaft member, the decelerator comprising:
- a bearing section that receives a drive force from the drive shaft member;
- a covering section that surrounds an outer periphery of the bearing section and that contacts and covers the bearing section;
- and
- a gear surrounding an outer periphery of the covering section and rotating in contact with the covering section, wherein
- the covering section includes a holding section that holds lubricant.
