OMS 05 hydraulic motor
3 week ago
Product details
The OMS 11 hydraulic motor is not a publicly standardized model, but based on the typical design characteristics of the OMS series hydraulic motors, it can be inferred to possess the following technical features:
1. Low-Speed, High-Torque Output:
OMS series hydraulic motors typically employ internal curve radial ball-piston or cycloidal gear designs, transmitting power through rolling contact between steel balls/gears and tracks to achieve high torque output at low rotational speeds. This characteristic makes them suitable for direct-drive applications involving high loads, such as the walking systems of construction machinery and winches in mining equipment.
2. Compact Structure with High Power Density:
The OMS series may adopt a modular design to optimize internal flow paths and bearing layouts, enabling high torque output within a limited volume. The housing material may be cast iron or aluminum alloy, balancing strength and weight to meet the lightweight requirements of mobile equipment.
3. Highly Reliable Sealing System:
To cope with high-pressure conditions, the OMS 11 may be equipped with high-pressure shaft seal technology to support high backpressure scenarios (e.g., closed-loop hydraulic systems) and prevent hydraulic oil leakage. The sealing materials may be wear-resistant composite materials to extend service life and reduce maintenance frequency.
4. Multi-Stage Variable Displacement Adjustment (Optional):
Some high-end models may offer two-stage or three-stage variable functionality, allowing dynamic matching of rotational speed and torque through adjustable displacement. This characteristic is suitable for applications requiring a wide speed ratio range, such as the rotation mechanisms of drilling rigs.
II. Inferred Performance Parameters (Based on Similar Models like OMS 80/125/160)
【表格】
Parameter Category Typical Range
Displacement 80–200 cc/rev (assuming the OMS 11 is a small-displacement model, likely close to 80–125 cc/rev)
Rated Pressure 16–20 MPa (peak pressure may exceed 25 MPa, supporting short-term overload conditions)
Speed Range Continuous speed: 50–800 rpm; maximum speed: 1,000 rpm (intermittent operation)
Torque Characteristics Rated torque: 50–200 N·m (depending on displacement); starting torque approximately 90% of rated torque
Efficiency Metrics Volumetric efficiency ≥92%; mechanical efficiency ≥88%
Applicable Media Mineral oil, environmentally friendly hydraulic fluids, etc.
III. Inferred Application Fields
1. Construction Machinery:
Walking drives for small excavators; slewing mechanisms or winch systems for cranes.
2. Mining Equipment:
Rotation units for drilling rigs; small hoisting winches or drive motors for underground transport vehicles.
3. Agricultural Machinery:
Hydraulic drive systems for tractor-mounted equipment (e.g., harvesters, seeders).
4. Industrial Automation:
Joint drives for light-duty robots; material mixing equipment or rotary worktables.
IV. Selection Recommendations (for Alternative or Reference Models)
1. Clarify Operational Requirements:
Determine the required torque, speed range, and pressure rating, and prioritize models with matching displacement (e.g., OMS 80 for light-load scenarios; OMS 125/160 for medium loads).
2. Focus on Sealing and Durability:
For high-pressure or contaminated environments, choose models with wear-resistant seals and reinforced bearings.
3. Variable Adjustment Needs:
If a wide speed ratio range is required, select models supporting multi-stage variable displacement.
4. Installation and Maintenance Convenience:
Verify the output shaft type (flange-mounted, through-hole, etc.) and interface dimensions to ensure compatibility with existing systems.
