| 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 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. |
|
| MORE POWER STROKES PER REVOLUTION |
| The 37 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. |
| SAE 'D' MOUNTING |
| The 37 Series mounting configuration conforms to SAE 'D' 4-bolt specification, with the exception of the omission of the undercut on the splined shaft. |
| 1S or 1L |
| 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. |
| BEARING LOADING |
| The bearings in the 37 Series standard motor can accept radial load per the radial capacity chart. Thrust loading is not recommended. For thrust-type applications, see the Code 62 standard motor. |
| HORSEPOWER LIMITATION |
| Maximum horsepower limitation may vary with different applications. When using the 37 Series above 175 HP, consult a Rineer Application Engineer. |
| CASE DRAIN AND CROSS PORT LEAKAGE |
| The combined case drain and cross port leakage of the 37 Series Motor is approximately 1 GPM per 1,000 PSI. This will vary with the oil viscosity and internal clearance selection. |
| ROTATION |
| The 37 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. |
