Title: Hydraulic gear pump or motor
Inventor: MIKI MASAYUKI
IPC: F04C2/18
Filed: 1984-10-08
Abstract: PURPOSE:To prevent tip leak from increasing as well as to make excellent volumetric efficiency securable all the time, by forming an inner surface of a peripheral wall member hitting a tip seal part with a high hardness material being more hard to be cut than the tip of a gear, for example, a ceramic coating layer. CONSTITUTION:A quarter circumferential part on an inner surface of a casing 5 at the side of a low pressure port 12 hitting a tip seal part is covered with a high hardness material being more hard to be cut than each tip of gears 3 and 4, for example, ceramic coating layers 15 and 15 in proper thickness. In time of motor operation, if these gear 3 and 4 move to the side of the low pressure port 12, each tip of these gears slidingly comes into contact with these coating layers 15 and 15, whereby the part of the tip is cut till an optimum clearance is produced between the tip and these layers 15 and 15. Therefore, even if a turning center of these gears 3 and 4 is moved to some extent due to a hydraulic variation at the inside of each of bearings 8 and 9 with a change of working conditions, it keeps up the optimum clearance between the tip and these coating layers 15 and 15 forming a seal surface. With this constitution, even if the working conditions are changed to some reason, a tip leak is in no case increased, thus excellent volumetrical efficiency is securable.
