Abstract

The volumetric linear motor of the present invention, the linear motor is composed of a motor stator and a motor rotor. The upper sleeve is fixed in the lower joint, and the upper sleeve is provided with a long opening for limiting the rotor joint; the rotor joint is driven by the motor rotor to make a reciprocating linear motion in the long opening. In the volumetric linear motor of the present invention, the centrifugal circular motion of the motor joint becomes up-and-down reciprocating motion, forming a volumetric motor with a "linear" output form, expanding the application range of the linear motor, simple and reasonable in structure, and low in production cost , the beneficial effect is remarkable, and it is convenient for application and promotion.

Description

technical field [0001] The invention relates to a volumetric linear motor, more specifically, to a volumetric linear motor whose centrifugal circular motion is reciprocating linear motion. Background technique [0002] The screw rotor is a tool that relies on a volumetric hydraulic motor for drilling operations. The hydraulic pressure drives the motor rotor to rotate eccentrically. The power output by the motor rotor is transmitted to the drill bit through the cardan shaft and the transmission shaft in turn, and finally the drilling is realized through the drill bit. Operation. For example, the patent document whose patent number is ZL200610021439.8 and the invention name is "a metal rotor screw rotor", specifically discloses a screw rotor with a metal rotor. [0003] Positive displacement motor is composed of motor stator and motor rotor, such as figure 1 As shown, the motion track diagram of the rotor of the existing volumetric motor is given. It can be seen that during ...
