Herringbone Gear Reducer最先出現(xiàn)在DEZHOU L&A PETROLEUM MACHINERY CO.,LTD。
]]>Product Description:
Our company produces gears and gear reducers utilizing Lufkin herringbone gear technology. The gear processing is carried out with specialized equipment, featuring a left and right helix angle of 30o. The diameter is controlled using specialized tools and an expansion method. Thanks to the unique characteristics of gear planing, our herringbone gears offer balanced forces, no axial force, and enhanced load-bearing capacity, resulting in a longer lifespan.
The reducer casing and cover undergo annealing before processing, which reduces casting stress by 90%. This ensures that the joint surfaces can be disassembled without deformation.

I. The Principle of Drill Motor
Drill motor is a kind of PDM (positive displacement motor) that converts the hydraulic pressure energy into mechanical energy. As the high-pressure drilling mud passes the motor inside, the motor generates torque which drives the rotary movement of the rotor in motor. The torque and the movement of the motor are delivered to the bit by driving shaft so as to make the drilling work.
II. The Components and Their Functions
DY-drill motor mainly consists of by-pass valve, motor, universal shaft, and drive-shaft. There is also a bent-sub in bent housing drill motor.
III. Model
we can provide 17 different series, including 45, 60, 73, 89, 95, 120, 130, 140, 146, 165,172, 185, 197, 203, 216, 244, 286, and each series has three categories, which are vertical motor, single bent angle motor, double bent angle motor.
Drill motors are available for the drilling in vertical wells, directional wells, cluster wells and horizontal wells. Especially, the minor diameter motors represented by 5LZ73, 7LZ89, 7LZ95, 7LZ120 etc. can be used for the drilling applications in both casing window sidetracking and workover operations.
