Bearings
- Functions:
• Support radial load
• Support thrust or axial loads
• Secure the cone on the leg
- Supporting loads is achieved by outer and nose bearing
- Ball and friction bearings secure the cone on the leg
- Two different bearing are available: antifriction and friction
- Antifriction bearings or roller are two types: Roller-ball-roller (RBR), and roller-ball-friction
- RBR, nose roller; intermediate ball; and outer roller
- The ball secure the cone
- Size influenced by journal angle and cone size
- RBR suffers from spalling of the races of the pin
- RBR bit have short life
- Normally used with bit with diameter greater than 12.25 in with adequate space and in situation where high rotary speed is required
A tricone bit is a drill bit with a head that is divided into three main parts.
The tricone bit consists of three rotating cones working inside each other and each with its own row of cutting teeth.
The tricone bit has three roller cutter cones with a series of teeth that crush rock on the rock face as they roll over the face.
A tricone bit is a drill bit with a head that is divided into three main parts.
