Abstract
Description
technical field
[0001] The invention relates to the technical field of digital home, in particular to a screw drive device, electronic equipment and a table. Background technique
[0002] The screw nut mechanism is also called the screw transmission mechanism. It is mainly used to convert rotary motion to linear motion or convert linear motion to rotary motion. There are those that mainly transmit energy (such as screw presses, jacks, etc.); there are also those that mainly transmit motion, such as the feed screw of the machine tool workbench); there are also screw transmission mechanisms that adjust the relative positions of parts. The screw nut mechanism is divided into a sliding friction mechanism and a rolling friction mechanism. The sliding screw nut mechanism has simple structure, convenient processing, low manufacturing cost and self-locking function, but its frictional resistance torque is large and transmission efficiency is low (30%-40%). Although the structure ...
