GEAR MOTORS; convert hydraulic pressure and flow into torque and angular displacement, rotary mechanical power, applied to a load via the shaft.
We shall be presenting the range of gear motors available from jbj Techniques over the coming weeks starting with the Group 3 high pressure capacity gear motors.
Displacements from 22 to 87 cc/rev, inlet pressure 160 to 295 bar, outlet pressure 150 to 270 bar, speed 2000 to 3500 rpm, with a drain line pressure of 6 bar.
A robust construction robust thanks to the cast iron front flange and rear cover. These hydraulic gear motors have high overall efficiencies, normally above 90%. The product range is available in a wide range of mounting flanges and port sizes, to meet European and international standards including SAE and DIN. Teflon® coated shaft-bearing surfaces are available for long service life.
The R&D department equipped with the latest testing equipment have analysed mechanical, hydraulic, acoustic and vibration criteria for performance and durability in the toughest working conditions. This has resulted in the optimisation of the compensation geometry (used to balance the dynamic thrust caused by pressure in gear vanes), gear profiles and the undercut drain on the bushings in order to increase product reliability and reduce noise levels resulting in prime performance gear motors.
These hydraulic gear motors can be supplied in single or bi-rotational formats and units are available with a comprehensive range of mounting flange and shaft options including specific designs to accommodate high radial loads.
A complete range of integrated relief valves and anti-cavitation valves to suit a wide range of applications are available as standard.
A variety of materials used within the construction process ensure suitability for a wide range of fluids and environments.
