Description

Technical Field

[0001] This utility model relates to the field of drive device technology, specifically a single worm gear drive device. Background Technology

[0002] In the fields of chemical engineering, food processing, and building materials, the uniform mixing of materials is a crucial step in the production process. As the core equipment for achieving this, the performance of the mixing machine's transmission system directly determines the mixing efficiency and effect. Currently, most mixing machines use direct gear meshing or V-belt drives.

[0003] In existing technologies, direct gear meshing transmission can easily generate significant impact and noise due to the rigid contact between gears. Especially under fluctuating loads, this not only accelerates gear wear, reduces transmission accuracy and equipment lifespan, but also disrupts the uniformity of material mixing due to vibration. While V-belt drives are prone to slippage between the V-belt and pulleys, leading to unstable transmission ratios and difficulty in precisely controlling the rotational speed of the mixing components, directly impacting the mixing effect. Furthermore, V-belt drives have relatively low efficiency, and the belt is prone to aging and loosening after prolonged use, requiring frequent tension adjustments and increasing maintenance costs and workload. Therefore, improvements to existing technologies are necessary. Utility Model Content
