HPB Series

Example of Model Selection

HPB3-1000CD31H means the hydraulic transmission device adopts single-grade planetary reducer transmission with modulus of gearbox being 3 and total displacement of 100ml/rev; the output shaft adopts screwed connection. Hydraulic motor distributor is D31 and the rated pressure grade is 20MPa.

Description on Parameters

1. The total displacement is calculated by multiplying hydraulic motor displacement with reduction transmission ratio.

2. Rated torque is the actual output torque taking transmisson efficiency into account when system pressure is 16MPa or 20MPa.

3. Transmission efficiency includes the mechanical efficiency of hydraulic motor and the mechanical efficiency of planetary reducer.

Description on Selection of Model

1. HPB hydraulic transmission device can work under high pressure.

2. The max permissible pressure of the housing is 0.8MPa. If you have any special requirements, please contact the manufacturer.

3. Hydraulic oil: recommend using high quality, anti-foaming and anti-oxidation mineral hydraulic oil. The ideal working oil temperature is 30℃ to 50℃ and the permissible oil temperature is between-20℃ to 80℃ When oil temperature is lowerthan 10℃.Low-freezing hydraulic oiI must be used. The viscidity of hydraulic oil is between 40-60 CST centistokes and the permissible viscidity is 5-300 CST centistokes.

4. The recommended hydrauIic oil fiItering precision is 25μm or higher;

5. The hydraulic transmission device can rotate in both directions; please see the details in the attached charts. If users require the equipment to rotate in opposite direction, please make notes when you place orders.

6. Positioning of oil drain: XHSC transmission device allows to be installed in any direction. To ensure the lubrication of all kinematic pair, it's required to fill hydraulic oiI into lhe motor before Working. The selection of position of oil drain port must be able to ensure that the housing is fulI of hydraulic oil when it operales.

7. Selection of distributor：All sorts of hydraulic transmission device can select to use the distributors of various specifications according to the requirements of different working conditions The principle for selection of distributor: to select distributor according to the using

pressure, rotation speed，flow, connecting method and the requirements of the integrated valve group; installation of distributor: the direction of oil inlet and outlet of distributors allows to rotate with interval of 72°around the external installation and connection location. However, when the distributor is rotated while the bolt is released, be careful not to damage the seal function of plane O-ring．
