| 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. Drill motors come standard with viton compound spring loaded lip seals. High pressure seal packages are available for additional charge. |
| 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 for the Code 62 motor 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 |
| The 125 Series High Performance Motor is designed for external case drain. Two 1/2 inch o-ring boss ports are supplied (3 on 4-port models); use the port at the highest elevation. In addition, the HD Drill Motor has an elevated case drain port in the rear seal plate to lubricate the rear bearing. 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 single stacked motor is approximately 1 to 1-1/2 GPM per 1,000 PSI, while the double stacked motor is approximately 2 GPM per 1,000 PSI. This will vary with the oil viscosity and internal clearance selection. |
| ROTATING GROUP - 2S or 2L |
| When rotating at speeds below 100 RPM, 2L (Low Clearance) design should be used. 2S design should be used when normal speeds are above 100 RPM. |
| ROTATION |
| The 125 Series 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 ports nearest the shaft output end (A1 and A2). |
|
| MORE POWER STROKES PER REVOLUTION |
| The 125 Series has six stator cavities and 16 rotor vanes. Each rotor vane works in each stator cavity once per revolution, which results in 96 power strokes per revolution. This helps produce higher mechanical efficiency and flatter torque curves. |
| HORSEPOWER LIMITATION |
Calculated maximum horsepower for the 125 series is achieved from the largest displacement and will be reduced per given smaller displacement. When using the 125 Series High Performance Motor above 80% of maximum HP or 200 c.i.d. & 4000 PSI, consult a Rineer Application Engineer.
Maximum Calculated Horsepower (with largest displacement):
125 Hi-Pressure 390 HP
125 Hi-Pressure 4-port 780 HP |
| 4-PORTED MOTOR CONFIGURATION |
| 4-Ported motors have displacements normally ranging from 120 in3 to 250 in3 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. |
| HIGH PERFORMANCE MOTOR, DBL. SPLINED |
| The 125 Series 4-Ported Motor is available with the standard splined shaft extending through both the front and rear housings. |
| BEARING LOADING |
| The tapered roller bearings in the 125 Series High Performance motor can accept thust load up to 13,900 lbs. dynamic or 147,000 lbs. static. Radial loading is also permissible up to 20,000 lbs. dynamic or 125,000 lbs. static. In the case of the HD Drill Motor, the dynamic and static loads are much higher. For details, see the Bearing section located on this site. If necessary, consult with a Rineer Application engineer for optional bearing configurations to match your application. |
| 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. |
