Patent number: 9976373Abstract: A blowout preventer may be used for shearing an object positioned in a vertical bore extending through the blowout preventer. The blowout preventer includes a shear ram movable towards the tubular, the shear ram including a biasing mechanism for biasing against an interior surface of the blowout preventer body. In this way, the biasing mechanism urges the shear ram into axial engagement with an opposing shear ram movable towards the tubular during shearing operations. The biasing mechanism comprises a biasing member, such as a coiled spring, coned-disc spring, and/or coned-disc washer which urges the biasing mechanism into contact with the inner portion of the blowout preventer body.Type: GrantFiled: September 2, 2015Date of Patent: May 22, 2018Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Raul Araujo, Jeffrey Lambert
