Abstract
A sliding structure for high load and having high strength as well as sufficient lubricating performance, wherein a solid lubricating material is buried in a sliding surface, an oil reservoir of a predetermined capacity is formed on the reverse of the surface; oil supplying pores extend from the oil reservoir to the sliding surface; and a continuous pore material inserted into the oil supplying pore which provides a limited supply of oil to the sliding surface concerned.
Claims17
A sliding structure for a high load, comprising:
- a solid lubricating material buried in any one of a pair of surfaces sliding on each other under high load;
- an oil reservoir of a predetermined capacity formed at the reverse surface of any one of said sliding surfaces;
- an oil supplying pore extending from said oil reservoir to said sliding surface concerned;
- and
- a pore holding member having minute continuous pores and being substantially coextensive with said oil supplying pore, said pore holding member being inserted into said oil supplying pore such that when a lubricating oil is supplied to said oil supplying pore said pore holding member provides a limited supply of oil to said sliding surface concerned.
