| 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 seals are supplied as standard on the Rineer 37-57 Code 62 motors. Disogrin rod seals and wipers are used in some drill motor applications. |
| 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, minimum viscosity for the Code 62 should be maintained at 150 SSU or higher. 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. |
| HIGH PERFORMANCE MOTOR, FEMALE SHAFT |
| Female shaft motors are available with either female keyed or splined output. This shaft configuration allows for quick and easy installation by utilizing a torque arm mount. |
| BEARING LOADING |
| The tapered roller bearings in the 37-57 Series High Performance motor can accept thrust load up to 7,080 lbs. dynamic or 62,000 lbs. static. Radial loading is also permissible up to 9,840 lbs. dynamic or 50,000 lbs. static. For details, see the bearing data pages on this site. |

| 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 97 in3 to 114 in3 in the 57 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 requiements. 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 ). |
| 2S or 2L |
| When rotating at speeds below 500 RPM, 2L (Low Clearance) design should be used. 2S design should be used when normal speeds are above 500 RPM. |
| HORSEPOWER LIMITATION |
| Maximum horsepower limitation may vary with different applications. When using the 37-57 Series above 300 HP, consult a Rineer Application Engineer. |
| CASE DRAIN |
| The 37-57 Series High Performance 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. |
| TWO-SPEED OPERATION |
| The High Performance 4-Ported motor can be used as a two-speed when combined with external valving. A series parallel circuit can only be used when both cartridges are of equal displacement. A circuit using two-way or logic valves can be used with equal or unequal displacement cartridges. When using the logic circuit, it should be connected to insure proper mixing of oil in the circulating cartridge. Particular attention should be given to the size and flow capacity, as this valve must handle the displacement of the circulating cartridge when in the high speed mode. For example: a 37 C.I.D. + 26 C.I.D. = 63 C.I.D. with speed ratios of 3.08:1 or 1.48:1 |
