摘要： The invention relates to a roller assembly including a roller pin and a roller arranged to be mounted on said roller pin, seal means between the roller pin and the roller arranged to prevent leakage of a lubricant from a clearance between the roller pin and the roller. The roller pin includes a bore which acts as a lubricant reservoir and is arranged so that lubricant from the lubricant reservoir can flow into the clearance. The bore is further arranged to receive a stationary pressure equalisation means. The pressure equalisation means serves to substantially equalize the pressure of the lubricant in the clearance on the seal means with the pressure of drilling mud surrounding the roller during use of the roller assembly so as to prevent damage to or blow out of the seal means.

摘要： The invention relates to a stabilising band for a roller assembly of the type used in the drilling industry. The roller assembly includes a roller pin mounted within a bore of a roller and the stabilising band is configured so as to fit tightly about the roller pin with a minimal running fit and within an annular groove formed in a wall of the bore of the roller.

摘要： The invention relates to a roller assembly (20) including a roller pin (22) and a roller (24) arranged to be mounted on said roller pin, seal means (34a,34b) between the roller pin and the roller arranged to prevent leakage of a lubricant from a clearance between the roller pin and the roller. The roller pin includes a bore (22c) which acts as a lubricant reservoir and is arranged so that lubricant from the lubricant reservoir can flow into the clearance. The bore is further arranged to receive a stationary pressure equalisation means (36). The pressure equalisation means serves to substantially equalize the pressure of the lubricant in the clearance on the seal means with the pressure of drilling mud surrounding the roller during use of the roller assembly so as to prevent damage to or blow out of the seal means.

摘要： The invention relates to a roller assembly (20) for a rotary roller reamer (10). The roller assembly (20) includes a roller pin (22) and a crushing roller (24). The crushing roller (24) is arranged to be mounted on the roller pin (22) and to rotate thereabout. The roller assembly (20) is connected together so as to form a single cartridge which can be inserted into a pocket (18) of the rotary roller reamer (10) and secured thereto using a single fastener device.
