Abstract
A grease packing jig includes: a support table on which a bearing is placed; a disc-shaped inner lid placed on an inner ring of the bearing; an upper lid, and pressers arranged to engage with an upper surface of the upper lid. The upper lid is disc-shaped, has a larger diameter than the inner lid, has a grease pumping port and has a lower surface formed with an inner lid housing recess so as to leave a grease pumping space between the lower surface and an upper surface of the inner lid as well as between the lower surface and an outer circumferential surface of the inner lid. Grease can be packed into a gap space in the bearing from a grease packing port provided between an inner circumferential surface of the inner lid housing recess and the outer circumferential surface of the inner lid.
Claims11
A grease packing jig for a bearing, comprising:
- a support table for supporting a bearing which has an inner ring and a plurality of rolling elements arranged equidistantly on an outer circumferential surface of the inner ring by means of a retainer, with a first end surface of the inner ring facing downward;
- a disc-shaped inner lid for covering at least part of a second end surface of the inner ring;
- a disc-shaped upper lid having a larger diameter than the inner lid, and including a grease pumping port, and a lower surface formed with an inner lid housing recess for housing the inner lid such that a grease pumping space is formed between the lower surface of the upper lid and an upper surface of the inner lid as well as between the lower surface of the upper lid and an outer circumferential surface of the inner lid so that grease can be packed into a gap space in the bearing from a grease packing port provided between an inner circumferential surface of the inner lid housing recess in the upper lid and the outer circumferential surface of the inner lid;
- a first presser disposed on the support table and configured to engage with an upper surface of the upper lid and press the upper lid downward, wherein the first presser includes:
- a holding rod provided at a first location on an upper surface of the support table such that the holding rod of the first presser pivots outwardly with respect to the support table, and
- a holding plate configured to engage the upper surface of the upper lid and press the upper surface of the upper lid with a spring when the holding rod of the first presser is raised to an upright position;
- and
- a second presser disposed on the support table and configured to engage with the upper surface of the upper lid and press the upper lid downward, wherein the second presser includes:
- a holding rod provided at a second location on the upper surface of the support table such that the holding rod of the second presser pivots outwardly with respect to the support table, and
- a holding plate configured to engage the upper surface of the upper lid and press the upper surface of the upper lid with a spring when the holding rod of the second presser is raised to an upright position.
