Description

1. Brief introduction

IY series hydraulic transmission drives consist of hydraulic motor, planetary gearbox, disc brake and multi-function distributor. It features small radial dimension, light weight, high torque and high starting efficiency, good stability at low speed, low noise and good economy. In addition, the output shaft can bear large external radial and axial load. They are widely used in construction engineering, railway, road, ship, petroleum, coal mine, metallurgy industries. Different brakes and distributors with functional valves are available to meet customers' requirements.

2. Model Options

3. Options Example

IY2.5-800CD31represents that the hydraulic transmission drive uses one stage planetary gearbox, gearbox module is 2.5, total displacement is800ml/rev, the output shaft uses thread flange connection, and the distributor of the hydraulic motor is D31.

4. Specification explanation

1) Total displacement is determined by hydraulic motor displacement multiplies transmission ratio of planetary gearbox.

2) Rated torque is the actual output torque considering pressures lose of 2MPa and transmission efficiency when the system pressure is 16Mpa or 20Mpa.

3)Transmission efficiency includes mechanical and volumetric efficiency of hydraulic motor and mechanical efficiency of planetary gearbox.

5. Selection instruction

1) IY series hydraulic transmission drives can run at high back pressure. The allowable back pressure is 10MPa under continuous working condition.

2)The maximum allowable pressure of casing is 0.1Mpa. If the back pressure at the system return line is higher than 0.1MPa, please specify it when place an order.

3) Hydraulic oil: It's recommended to use high quality mineral-based hydraulic oil, which is anti-wear, anti-foam and anti-oxidation. The ideal oil temperature is between 30'℃ and 50"℃, and the allowable oil temperature is between-20℃and 80℃. If the temperature is higher than 60'℃ or lower than 10℃, please use low-freezing hydraulic oil. The oil viscosity is between 40cSt and 60cSt, and allowable viscosity is between5cSt and 3000cSt. If customer chooses water-based emulsified liquid as medium, please contact us for right products.

4) It is recommended to use hydraulic oil with a filter rating of 25μ m or even higher.

5) The hydraulic transmission drives are bi-directional. See attached drawings for more information. Reverse direction is available if customers request so when place an order.

6) Positioning of drain line. IY hydraulic transmission drives can be installed in any direction. To ensure the smooth movement of kinematic pairs in the hydraulic motor, please fill the motor casing with hydraulic oil. The oil drain port must be positioned in such a way that there is always sufficient hydraulic oil in the motor casing. If the output shaft is pointing downward, please add a check valve of 0.5bar at the oil drain port.

7)Selection of distributors: Customers can choose different types of distributors for the hydraulic transmission drive based on different working conditions. Please take into consideration working pressure, speed, flow, connection type and function of integral valve block when select distributors. Installation of distributor: The direction of oil port can rotate by every 72°Please take care not to damage the 0 ring when rotate the distributor.

8) If customers require over power operation, please contact us. We can greatly improve the performance of the product and transmission power by giving special treatment to the material and surface of moving parts inside planetary gearbox.

9)We can add an output gear to the hydraulic transmission drives to gain hydraulic slewing drives, if you need it please contact us.
