Orbital Hydraulic Motor BMER-2 series Wheel Motor Description
ChangJia Keeping up with the market demand, the BMER series Orbital hydraulic motor was developed for the scissor-type aerial vehicle to "Add Full Horsepower" to its walking drive system.
BMER series motor adapt the advanced Geroler gear set designed with high speed distribution flow and high pressure,and have good stability in low speed,and can keep high volume efficiency.The unit can be supplied the individual variant in
operating multifunction in accordance with requirement of applications.
Characteristic features;
Advanced manufacturing devices for the Geroler gear set,which use low pressure of start-up,provide smooth and reliable operation and high efficiency.
The output shaft adapts in needle roller bearings that permit high axial and radial forces.The case can offers capacities of high pressure and high torque in the wide of applications.
"Advanced design in high speed distribution flow,which can automatically compensate in operating with high volume efficiency and long life,provide smooth and reliable operation.
"Lowest leakage rate,most accurate timing methods.Commutator rotates 6x faster than shaft speed.it make the distribution in a high precision reduces life-cycle cost,maintain high volume efficiencies and can run very smoothly at low speed,gear box not required.
Orbital hydraulic motor product advantages：
- The optimized high-pressure combined sealing design provides excellent sealing performance and reliability
- It adopts needle roller bearing structure, which has strong ability to bear axial and radial loads.
- Unique balance disc design to ensure smooth operation at low speed and high pressure
- The full flow cooling treatment of the linkage mechanism to obtain a longer life
- The advanced distribution system design greatly improves the efficiency and makes the motor more compact
- Provide a variety of optional flange connection sizes for easy installation
