| VANE CROSSING VANE |
| The Rineer patented vane crossing vane design produces much higher volumetric and mechanical efficiencies than is possible with a standard vane type design. This design provides a sealing vane between cavities to improve mechanical and volumetric efficiencies. |
| STARTING AND STALL TORQUE |
| The Rineer motor produces torque curves which are virtually flat with starting and stall torque equal to approximately 90-94% of theoretical torque. |
| SEALS |
| Viton compound spring loaded lip seals are supplied as standard on the Rineer 37-57 Code 62 Drill series motors. These seals have proven to be superior for higher temperatures on the shaft associated with thru hole air. |
| FILTRATION |
| 25 micron minimum |
| FLUID |
| We suggest premium grade fluids containing high quality rust, oxidation and foam inhibitors, along with anti-wear additives. For best performance, viscosity should be maintained between 100 and 200 SUS at operating temperature. Fluid temperature should not exceed 180o F. Elevated fluid temperature will adversely affect seal life while accelerating oxidation and fluid breakdown. Fire resistent fluids may be used with certain limitations. Contact Rineer for additional information. |
| CASE DRAIN CIRCULATION |
| Fluid should be circulated through the case when a temperature differential exists between the motor and the system in excess of 50o F. Should this occur, contact a Rineer Application Engineer. |
| MOUNTING |
| The mounting position is unrestricted. The shafts, pilots, and mounting faces should be within .002 TIR. |
| INTERMITTENT CONDITIONS |
| Intermittent conditions are to be less than 10% of every minute. |
| BEARING LOADING |
| The tapered roller bearings in the 37-57 Drill Series can accept thrust load per the thrust capacity charts. Some radial loading is also permissible. For details, see the bearing data pages on this site. Consult with a Rineer Application Engineer for optional bearing configurations. |
|
| MORE POWER STROKES PER REVOLUTION |
| The 37-57 Series has four stator cavities and 10 rotor vanes. Each rotor vane works in each stator cavity once per revolution, which results in 40 power strokes per revolution. This helps produce higher mechanical efficiency and flatter torque curves. |
| 4-PORTED MOTOR CONFIGURATION |
| 4-Ported motors have displacements normally ranging from 24 in3 to 74 in3 in the 37 series motor and are comprised of two rotor stator packages separated by a mid-inlet housing. This allows the packages to function individually or in parallel. Any of the standard displacement packages may be combined to satisfy total displacement requirements. In addition, the 57 series (48 and 55.5 in3) may be combined with any 37 series package in a 4-port configuration (e.g. 26 in3 + 55.5 in3 = 82 in3 ). |
| SUBLOCK COLLAR SYSTEM |
| The Sub-Lock Collar is a shaft saving device that allows for secure attackment of the motor shaft to the drill string. The spline of the sub-lock is fitted to the mating spline on the shaft and then tack welded to the drill string pipe. This avoids any welding directly onto the shaft. |
| HORSEPOWER LIMITATION |
| Calculated maximum horsepower in each series is achieved from the largest displacement and will be reduced per given smaller displacement. When using the 37-57 Drill Series Motor above 80% of maximum HP per displacement, consult a Rineer Application Engineer. |
| CASE DRAIN |
| The 37-57 Series Drill motor is designed for external case drain. Two case drain ports are supplied; use the port at the highest elevation. We recommend case drain pressure of 35 PSI or less when using the standard seals. |
| ROTATION |
| The 37-57 Series Motor rotates equally well in either direction and smoothly throughout its entire pressure and speed range. Looking into the end of the shaft, rotation is clockwise when oil is supplied to the port nearest the shaft. |
