SINTERED BEARING AND METHOD FOR PRODUCING SINTERED BEARING
In a sintered bearing, a problem is to improve mechanical strength and vibration resisting properties and prevent a rotation shaft from being damaged.A sintered bearing 20 according to the present invention is made of a sintered compact containing nickel silver (Cu-Ni-Zn) as a base. Here, in the sin...

| description | In a sintered bearing, a problem is to improve mechanical strength and vibration resisting properties and prevent a rotation shaft from being damaged.A sintered bearing 20 according to the present invention is made of a sintered compact containing nickel silver (Cu-Ni-Zn) as a base. Here, in the sintered bearing 20, P is not added in the sintered compact. Alternatively, a content of P in the sintered compact is less than 0.05 mass% in terms of mass ratio to a total mass. Consequently, crystal grains constituting the sintered compact can be micronized. In particular, in the sintered bearing 20, an average crystal particle diameter of the crystal grains constituting the sintered compact is 20 µm or less. Consequently, the mechanical strength and the vibration resisting properties can be improved, and the rotation shaft can be prevented from being damaged. |
