In order to reduce the drive shaft rotating parts is between the body shell friction axial and radial components of the set, I drilling company there are different parts of the transmission structure. 3.5MPa water pressure dropped to the drive shaft parts, upper and lower radial bearings, thrust ball bearings using the middle, water pressure dropped to 7.0MPa components up and down the shaft using carbide radial bearings, thrust the middle with a ball bearing Group to raise the carrying capacity of the transmission shaft and the life. |
