Abstract
A friction applying apparatus and a linear guide apparatus having the same, according to the present invention can uniformly contact allover contacting faces of sliding members to the contacted members so as to reduce abrasion in the sliding members and the contacted members, and may maintain appropriate frictional force and precision. In the friction applying apparatus forcing the sliding members moving along guide rails for generating friction, the sliding member is made of a material having elastic modulus being 5000 MPa or less and Vickers hardness being 400 or more.
Claims19
A friction applying apparatus comprising:
- a sliding member moved along a contacted member;
- a press member pressing the sliding member against the contacted member so as to generate a friction between the sliding member and the contacted member,
- wherein at least a portion of the sliding member that is brought in friction contact with said contacted member is made of a material having elastic modulus being 5000 MPa or less and Vickers hardness being 400 or more,
- wherein a friction coefficient of the sliding member ranges from 0.08 to 0.13, and
- lubricant is disposed so as to lubricate between the sliding member and the contacted member,
- wherein said porous ceramic is a hard porous carbon material.
