Abstract
A lubricant supply device includes a porous body including a first porous portion and a second porous portion in contact with the first porous portion, the porous body being impregnated with a lubricant. A penetration depth of the lubricant in the second porous portion is larger than a penetration depth of the lubricant in the first porous portion.
Claims14
A lubricant supply device comprising:
- a porous body including a first porous portion and a second porous portion in contact with the first porous portion, the porous body being impregnated with a lubricant, wherein a penetration depth of the lubricant in the second porous portion is larger than a penetration depth of the lubricant in the first porous portion.
A method for manufacturing a lubricant supply device including a porous body including a first porous portion and a second porous portion in contact with the first porous portion, the porous body being impregnated with a lubricant, a penetration depth of the lubricant of the second porous portion being larger than a penetration depth of the lubricant of the first porous portion, the method comprising:
- compressing one porous material to form the porous body including the second porous portion that is a compressed portion of the one porous material and the first porous portion that is a portion having a smaller degree of compression than that of the second porous portion.
A method for manufacturing a lubricant supply device including a porous body including a first porous portion and a second porous portion in contact with the first porous portion, the porous body being impregnated with a lubricant, a penetration depth of the lubricant of the second porous portion being larger than a penetration depth of the lubricant of the first porous portion, the method comprising:
- bringing a first porous body constituting the first porous portion and a second porous body constituting the second porous portion into close contact with each other to form the porous body.
A rolling sliding device comprising:
- a first rolling sliding member that has a first rolling sliding portion;
- a second rolling sliding member that has a second rolling sliding portion;
- a lubricant supply device;
- and
- a contact portion in which the first rolling sliding portion and the second rolling sliding portion come into contact with each other in at least one mode of rolling contact and sliding contact, wherein:
- a lubricant is supplied from the lubricant supply device to the contact portion;
- the lubricant supply device has a first porous portion, a second porous portion continuous with the first porous portion, and a porous body which is impregnated with the lubricant;
- a penetration depth of the lubricant in the second porous portion is larger than a penetration depth of the lubricant in the first porous portion;
- and
- a distance between the second porous portion and the contact portion is smaller than a distance between the first porous portion and the contact portion.
