How Hydraulic Variable Displacement Piston Motor works


Hydraulic Variable Displacement Piston Motor converts the hydraulic thrust on the cylindrical plunger into the torque of the output shaft through the swash plate mechanism or the connecting rod mechanism.

Hydraulic Variable Displacement Piston Motor converts the hydraulic thrust on the cylindrical plunger into the torque of the output shaft through the swash plate mechanism or the connecting rod mechanism. Its main working components are the plunger and the cylinder, which are easy-to-process cylindrical, easy to ensure precise clearance fit, so as to ensure high volumetric efficiency under high pressure, so Hydraulic Variable Displacement Piston Motor is generally made of High voltage series, Hydraulic Variable Displacement Piston Motor are generally reversible (a small part is irreversible). According to the arrangement and movement direction of the plunger, Hydraulic Variable Displacement Piston Motor can be divided into axial plunger type and radial plunger type. The plunger of the former is parallel to or intersects with the transmission shaft to form an acute angle, and the plunger of the latter is perpendicular to the transmission shaft.

Axial Hydraulic Variable Displacement Piston Motor can be divided into swash plate type and inclined shaft type. The center line of the plunger of the swash plate motor is parallel to the transmission axis and the plunger is reciprocated axially by the action of the swash plate. The center line of the plunger intersects the transmission axis (the included angle is not more than 40°); the swash plate motor is divided into through shaft type, non-through shaft type, sliding shoe type and point contact type; the inclined shaft type motor can be divided into two types according to the transmission form Hinged type, hingeless type, non-connecting rod type and connecting rod type, etc.
