Coaxial bidirectional stirring device

Abstract

The invention relates to a coaxial bidirectional stirring device which comprises an inner rotating shaft and an outer rotating shaft. The inner rotating shaft is sleeved with the outer rotating shaft and connected with the outer rotating shaft through inner shaft bearings. A planetary transmission is arranged between the inner rotating shaft and the outer rotating shaft and comprises a sun gear, planetary gears and a gear ring. The sun gear is fixed to the inner rotating shaft in a penetrating manner, the gear ring is arranged at the bottom of the outer rotating shaft, and the planetary gears are engaged with the sun gear and the gear ring. The coaxial bidirectional stirring device is compact in structure; in the use process, the inner rotating shaft is connected with a motor for rotation, and therefore the sun gear of the planetary transmission is driven to rotate, the outer rotating shaft connected with the gear ring is kept rotating at different speeds in the opposite direction, and a stirring tool is driven coaxially in the forward and reverse directions to run at different speeds at the same time; sufficient stirring is achieved, and efficiency is improved; and the inner shaft bearings are arranged between the inner rotating shaft and the outer rotating shaft, so that rotating friction is lowered, the service life of a part is prolonged, and the device is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the field of motors and electric appliances, in particular to a coaxial and different-speed forward and reverse multifunctional stirring device for electric household appliances. Background technique [0002] Most of the stirring shafts in the prior art are single-axis stirring, but the stirring material cannot be fully and comprehensively stirred in this case, and there are stirring misunderstandings, dead ends, sticking to the bottom, and sticking to the wall. When the agitator is running in this single shaft and one direction, the agitator will inertially run in the same direction as the agitator, and the agitator is chasing the agitator for processing, which obviously reduces the treatment effect on the agitator. [0003] At present, there is also a technology to realize two-way stirring, such as the patent number is CN204372118U, and the application date is 2015.01.04 "Coaxial two-way transmission mechanism". This coaxial ...

[0003] At present, there is also a technology to realize two-way stirring, such as the patent number is CN204372118U, and the application date is 2015.01.04 "Coaxial two-way transmission mechanism". This coaxial two-way transmission mechanism includes a shaft head, and a flat key is installed on the shaft head. Gear 1 is sleeved at the key, and a screw for fastening gear 1 is provided on the gear 1. Bearing 1, spacer 1 and bearing 2 are sleeved sequentially from the shaft end of the shaft head. Connect gear 2 and gear 3, and gear 2 and gear 3 are fixed by screws. The shaft end of the shaft head is sleeved with spacer 2 and a washer, and connected to the shaft head by countersunk screws to fix the overall structure. Although this coaxial two-way transmission mechanism The purpose of two-way stirring is achieved, but in actual work, the rotation of gear 1 follows the rotation of the shaft head, while the rotation direction of gear 2 and gear 3 is not limited by the rotation direction of the shaft head, and there is no transmission connection, so its stirring The effect is not obvious, especially the cell wall of the agitator cannot be effectively processed to extract phytochemicals
