Gear hydraulic motor / high-pressure

The construction (design principle) and materials of the KRACHT KM 2 series external gear motors make them perfect for use under the most extreme operating conditions. The main components form the housing and flange cover (see sectional drawing). They can be dynamically highly loaded, making them insensitive to pressure peaks and continuous vibrations. Large-surface-dimensioned, PTFE-Pb coated, bronze plain bearings on steel backs in the housing and flanged cover support the micro-finish ground bearing journals of the gear, which comprises the driving shaft pinion and driven shaft pinion. To realise optimum running properties the tooth flanks of the gear, which are produced from case-hardened steel, are ground. The high number of teeth (z = 14) in combination with a tooth shape developed for the special requirements of the hydraulics as well as the optimal layout of the expansion slots in the trapped-oil area achieve a considerable reduction in the volume flow variation and thus the pressure pulsation.
