Bent axis motors were developed to improve the operating and stall torque efficiencies of high-speed motors. The design (Fig. 5.15) operates in a manner similar…
The Vickers Model MHT50 vane motor with 38 in3/rev maximum displacement was chosen for an example. This motor is rated for a maximum pressure of…
The Char-Lynn 10,000 series motor with 40.6 in3/rev displacement was chosen for an example. (Notice that this displacement is approximately 10 times the displacement of…
The fixed displacement axial piston motor (Sauer-Danfoss Model 90-075 MF), comparable to the variable displacement axial piston pump (Sauer-Danfoss Model 90-075 PV), was chosen. This…
A Vickers Model 25M (65) vane motor was chosen for the comparison. This motor is rated for 3000 rpm at 2500 psi maximum pressure. It…
The gear pump design can also be used as a motor. The Hydreco Model 1919 motor has a theoretical displacement of 4.53 in3/rev, a maximum…
Manufacturer’s data for a gear motor are given in Fig. 5.2. These data serve as an example of typical data supplied by a manufacturer. The…
There are four sources of contamination in hydraulic fluid. 1. Built-in contamination. This is contaminate that was left in the system when it was assembled.…
There are three types of failure in a fluid power system. 1. Degradation. The performance of the component degrades over time as surfaces wear, clearances…
Two types of heat exchanger are used to cool hydraulic oil: (1) shell-and-tube and (2) finned tube. The shell-and-tube (Fig. 8.1) has a series of…
