A two-dimensional motor combined piston pump

Abstract

The present application discloses a two-dimensional motor combined piston pump that integrates two two-dimensional motor piston pumps to realize parallel output, including a two-dimensional motor and a two-dimensional piston pump, and the outer rotor of the two-dimensional motor also acts as a two-dimensional piston The piston and distribution mechanism of the pump rotate and move axially during operation. By integrating two single pumps to achieve parallel output, the piston pump has a larger power-to-weight ratio; part of the structure of the two-dimensional motor and the two-dimensional piston pump is shared, making the structure more compact; the rotor of the two-dimensional motor does not need bearings Support, avoid the problem of axial force affecting the motor life; use a two-dimensional motor to convert the rotation and axial motion of the rotor into magnetic coupling and decoupling, reduce friction and improve efficiency; the motor is a wet structure, with good heat dissipation, Not easy to cause sparks; using two-dimensional piston pump structure, high volumetric efficiency.

Description

technical field [0001] The present application relates to the fields of motor technology and fluid transmission technology, and in particular, to a two-dimensional motor combined piston pump composed of a two-dimensional motor and a two-dimensional piston pump. Background technique [0002] A motor is a component that converts electrical energy into mechanical energy to provide power, and is often used as a power source for pumps. An outer rotor motor is one in which the coils are on the stator and the permanent magnets are on the outer rotor. Compared with the ordinary motor, the rotor of the two-dimensional motor can also do a certain axial movement while rotating. A hydraulic pump is a hydraulic component that provides pressurized liquid in a hydraulic system, and is a conversion device that converts the mechanical energy of an electric motor or an internal combustion engine into hydraulic energy. The piston pump relies on the reciprocating motion of the piston, which m...
