Description

Technical Field

[0001] The utility model belongs to the technical field related to screw rod transmission, and particularly relates to a screw rod driven bidirectional motion linear slide module. Background Art

[0002] Screw drive is a common mechanical transmission method that converts rotational motion into linear motion, or converts linear motion into rotational motion. Screw drive consists of two parts: a screw and a transmission block. Screw drive also has a large transmission ratio, which can achieve a wide range of speed changes to meet the needs of different working conditions.

[0003] In actual use, the screw drive realizes transmission through the cooperation between the screw and the transmission block. The transmission block and the screw are worn out after a long period of rotation, which increases the friction between the two, resulting in the obstruction of the movement of the transmission block. The manual addition of lubricant increases the actual operation steps and affects the transmission efficiency. To this end, we provide a screw-driven bidirectional motion linear slide module to solve the above technical problems. Utility Model Content
