Description
Technical field
The utility model relates to blower technical field, especially a kind of blower with planetary gear.
Background technique
There are following characteristics in configuration aspects for planetary gear:
(1) sun gear, planet carrier and gear ring are all concentric, i.e., rotate around common axis.This can cancel such as hand
Jackshaft and intermediate gear used in dynamic speed changer；(2) all gears are intermeshed always, and shifting slide gear is not necessarily to when shift,
Therefore fretting wear, lasts a long time；(3) structure is simple, compact, and load is assigned on large number of tooth, and intensity is big；
(4) multiple transmission ratios be can get.
It finds after study, in " aeration " link of sewage treatment, generallys use a kind of blower: being rotated by a fan blade
Patting another fan blade makes its rotation, it is clear that and this have a very big drawback by way of patting transmission speed, high-intensitive,
It is prolonged to pat the abrasion that increase fan blade, greatly shorten its service life.And it is another simultaneously using two motor difference
The mode of driving, since two motor speeds are extremely difficult to unanimously, will lead to equipment failure and threaten personal safety.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, the purpose of the utility model is to provide a kind of blower with planetary gear,
Impeller of blower rotation is driven by outer ring wheel shaft and planetary gear, and changes the rotation direction of fan blade by one gear of engagement, it is real
Show the needs that two fan blades of blower are rotated towards different directions simultaneously, and can get more transmission ratios.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of blower with planetary gear, including type chamber, the upper surface of described type chamber is equipped with an air inlet, below the type chamber
Equipped with an air outlet, the front end of the type chamber is equipped with a cover board, and the front end of the cover board is equipped with an outer ring for having outer ring wheel shaft
Wheel, the type is intracavitary to be set side by side there are two fan blade, and the centre of the fan blade is run through by one end of a blade shaft, the blade shaft
The other end through the cover board and be socketed with a planetary gear, the planetary gear is taken turns with the outer ring and is engaged.
As further improvement of the utility model: there are two the planetary gear is set, two planetary gears directly with
The outer ring wheel engagement.
As further improvement of the utility model: there are two the planetary gear is set, one of them described planetary gear
It is directly engaged with outer ring wheel, another described planetary gear is then engaged again with a gear through the gear and the outer ring
Wheel engagement.
Compared with prior art, the utility model has the beneficial effects that
The utility model is simple and compact for structure, using a motor as power, passes through outer ring wheel shaft and planetary gear band
Impeller of blower rotation is moved, and changes the rotation direction of fan blade by one gear of engagement, realizes two fan blades of blower while court
The needs of different directions rotation, and can get more transmission ratios.
