| 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 |
| Buna N seals are supplied as standard on the Rineer motors. Viton seals may be ordered as an option. |
| 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 should be maintained at 100 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 |
| The 37-57 Series 4-Port Motor is designed for external case drain. Two 1/2 inch o-ring boss ports are supplied; use the port at the highest elevation. We recommend case drain pressure of 35 PSI or less when using standard seals. |
| 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. |
| CASE DRAIN AND CROSS PORT LEAKAGE |
| The combined case drain and cross port leakage of the 4-Port motor is approximately 1 to 1-1/2 GPM per 1,000 PSI per package. This will vary with the oil viscosity and internal clearance selection. |
| ROTATION |
| The 37-57 Series 4-Port Motor rotates equally well in either direction and smoothly throughout its entire pressure and speed range. Viewing the output shaft, rotation is clockwise when oil is supplied to the port nearest to the shaft. |
|
| 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. |
| HORSEPOWER LIMITATION |
| Maximum horsepower limitation may vary with different applications. When using the 37Series 4-Ported above 175 HP or the 57 Series 4-Ported Motor above 190 HP, consult a Rineer Application Engineer. |
| 4-PORTED MOTOR CONFIGURATION |
| 4-Ported motors have displacements normally ranging from 24 in3 to 74 in3 in the 37 Series or 96 in3 to 111 in3 in the 57 Series, 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 ). |
| 4-PORTED MOTOR, DOUBLE SPLINED |
| The 37-57 Series 4-Ported Motor is available with the standard (1-3/4") splined shaft extending through both the front and rear housings. |
| BEARING LOADING OPTIONS |
| The bearings in the standard 37-57 Series 4-Port motor can accept radial load per the radial capacity chart located in the BEARING section of this site. Thrust style motors are also available with tapered thrust bearings. See bearing charts for thrust loading capacities. See 37-57 Code 62 High Pressure series motors for additional heavy duty thrust bearing packages including drill motors. For additional thrust-type applications, contact Rineer for optional bearing configurations. |
| 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. |
| TWO-SPEED OPERATION |
| The 4-Ported Motor can be used as a two-speed when combined with external valving as illustrated. (See envelope page for a diagram of a typical circuit.) The series parallel circuit can only be used when both cartridges are of equal displacement. The 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 as illustrated to insure proper mixing of oil in the circulating cartridge. Particular attention should be given to the size and flow capacity of V2, as this valve must handle the displacement of the circulating cartridge when in the high speed mode. For example: a 37 C.I.D. + 16 C.I.D. = 53 C.I.D. with speed ratios of 3.31:1 or 1.43:1. |
