Micro gearboxes usually refer to gearboxes with a size of less than 50mm. The miniature gearbox has the characteristics of small size, light weight, low noise, high efficiency and practicality,which can used in many fields,such as home automation,communication equipment,robot,personal care. Common micro gearboxes are divided into square gearboxes and cylindrical gearboxes by shape. Here we focus on cylindrical gearboxes.
The cylindrical gearbox mainly adopts the planetary gear transmission mechanism, and the reduction ratio of the single-stage planetary transmission is 3~6, and the large transmission ratio range of 3~1526 can be realized through the multi-stage series connection. A multi-stage cylindrical gearbox that is driven by a row, usually with common inner teeth. In order to achieve a minimum volume, the internal teeth are usually manufactured integrally with the outer casing. Typical cylindrical gearboxes include internal gear housings, a sun gear, planetary gears, end caps, bearings, washer snap rings, and so on.
The micro gearbox is mainly composed of small modulus involute gears, and its gear modulus is usually 0.2, 0.3, 0.4, 0.5, 0.6, 0.8 and 1.0. Micro gearboxes
are divided into plastic gearboxes, metal gearboxes and hybrid gearboxes depending on the material. ZHAOWEI produces micro plastic gearboxes ,metal gearboxes and hybrid gearboxes,and our products is small volume,large torque,low noise and high efficiency,which can be used in many fields.
