Multi-axis gear speed reduction high-load servo power head and application method

Abstract

The invention provides a multi-axis gear speed reduction high-load servo power head and an application method. The multi-axis gear speed reduction high-load servo power head mainly comprises a servo motor, a motor connecting plate, lead screws, a small gear and a plurality of big gears, and is characterized in that the servo motor is installed on the motor connecting plate, the motor connecting plate is connected to a box body by screws, the small gear is arranged on a shaft of the servo motor in a sleeved manner, the small gear is meshed with the plurality of big gears in a transmission manner, each big gear form rigid connection with the corresponding lead screw through an expansion sleeve, one end of each lead screw is provided with an angular contact ball bearing and forms axial positioning through a locking nut, and an outer ring of each angular contact ball bearing is installed in a corresponding bearing pedestal and compressed by a bearing gland. The multi-axis gear speed reduction high-load servo power head is simple in structure principle, a multi-axis parallel transmission structure is adopted, and the axial bearing capacity of the lead screws is enabled to be improved by multiple times. In addition, speed reduction is performed through first-level gears, force increasing is realized, and the energy consumption of the motor is reduced. The multi-axis speed reduction high-load servo power head can be widely applied to servo pressure machinery, powder molding equipment, extrusion equipment, medical equipment and the military field, and effectively improves the bearing capacity of the mechanisms.

Description

[0001] Technical field: [0002] The invention relates to the technical field of mechanical transmission, in particular to a multi-axis gear reduction large-load servo power head and a use method thereof. [0003] Background technique: [0004] The screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, while having high precision, reversibility and high efficiency. specialty. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. Its significance is to change the bearing from a sliding action to a rolling action. [0005] The traditional servo power head (servo push rod) is driven by a screw (the screw can be a T-shaped screw, a ball screw or a planetary roller screw, etc.), and its axial load capacity is limited, and It needs to use a high-power servo ...
