Embodiment Construction

[0013] A double-acting vane-type secondary element is mainly composed of a rotor 4, a stator 2, a vane 3, a variable oil cylinder 10, a housing 1, and flow distribution plates 11 and 12. The variable oil cylinder 10 is composed of a variable rod 6, a variable piston 8, a variable cylinder 9 and the like. The variable cylinder 9 is fixed on the housing 1 by bolts, the spherical head end of the variable rod 6 is connected with the groove of the variable piston 8, and the other end of the variable rod 6 is fixed on the center line of the long radius arc or the short radius of the stator 2. at the centerline of the arc, figure 2 In the illustrated embodiment of the present invention, the other end of the variable rod 6 is fixed on the outer surface of the stator 2 at the centerline of the long-radius arc.

[0014] The oil inlet and outlet of the secondary element are of the same size, the vanes 3 are arranged radially along the rotor 4 (that is, the placement angle is zero), the...

Abstract

A double-effect vane secondary element, which is made up of a rotator, a stator, a vane, variable cylinder, a shell and a distributing plate. The variable cylinder is made up of a variable pole, variable piston, and variable shell. The variable shell is fixed on the shell through bolt, the sphere head of the variable pole is connected to the concave groove of the variable piston, another end of the variable pole is fixed on the external surface of the stator long radius arc center. The merits of the invention are: through the control to the stator position, the 'hydraulic motor' condition of the secondary element and the 'hydraulic pump' condition can convert each other, it realizes the reclaim and the reuse of energy.

Description

Technical field [0001] The invention relates to a double-acting vane-type secondary element, which belongs to the field of machinery. Background technique [0002] The secondary component refers to the component that can realize the mutual conversion of hydraulic energy and mechanical energy, also known as variable hydraulic motor / pump, it can work in both the "hydraulic motor" working condition and the "hydraulic pump" working condition, when the secondary When the element transitions from the "drag load" to the "load drag" working condition, it transitions from the "hydraulic motor" working condition to the "hydraulic pump" working condition, that is, it changes from the energy consumption working condition to the energy recovery working condition, This provides the possibility of energy recovery and reuse. [0003] Most of the existing secondary components are improved on the basis of the swash plate type plunger variable motor. The structure is mainly of the plunger typ...
