SHAFT CONNECTING STRUCTURE OF SWASHPLATE TYPE HYDRAULIC PUMP

摘要

PURPOSE: A shaft joint structure of a swash plate hydraulic pump is provided to significantly reduce the length of a shaft by joining both side ends of a connection shaft to one side of a cylinder block and each shaft to one lateral side of cylinder block. CONSTITUTION: A shaft joint structure of a swash plate hydraulic pump(100) comprises a pair of pump units(110,120) and a valve unit(130). A pump unit comprises inclined plates(114,124) and cylinder blocks(112,122). The cylinder blocks comprise pistons(113,123). The pistons are joined with shafts(116,126) by being in touch with the inclined plates and reciprocate by rotating. The valve unit comprises a valve block(131) which is equipped in between a pair of pump units. One side of a cylinder block is joined with each shaft. A connection shaft(132) which passes through the valve unit is joined to and interlocked with one side of the cylinder block in each pump unit.
