Abstract
The utility model discloses a speed reduction mechanism of an electric winch. The planetary gear speed reduction mechanism comprises a primary planetary gear group and a secondary planetary gear group; wherein, planetary gears in the primary planetary gear group are dual gears; the large gears and the small gears of the dual gears are respectively engaged with primary gear rings on a transmission case and primary sun wheels on a transmission shaft. Because the dual gears combine two levels of planetary gears, the utility model reduces the primary planetary frame and one sun wheel, thereby reducing the cost and improving the efficiency.
Description
Technical field
The utility model relates to the electric capstan technical field, relates in particular to the speed reduction gearing of electric capstan.
Background technology
At present known general capstan winch speed reduction gearing adopts the third-level planetary gear reduction, primary planet pinion is mounted on the transmission shaft latter end and its sun wheel connects transmission shaft, the pinion carrier of third stage compound planet gear and a meshed transmission gear behind the third-level planetary gear reduction, this gear meshes with winch drum more then, thereby realizes that cylinder rotates.Satellite gear progression is many like this, and friction force is bigger, causes retardation efficiency low, and cost is also higher simultaneously.
The utility model content
Technical problem to be solved in the utility model just provides a kind of efficient height, electric capstan speed reduction gearing that cost is low.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electric capstan speed reduction gearing, comprise transmission shaft, connect planetary gear reducing mechanism on the described transmission shaft, it is characterized in that: described planetary gear reducing mechanism comprises primary planet pinion group and secondary planetary gear group, wherein the satellite gear of primary planet pinion group is a dual gear, the big gear wheel of described dual gear and miniature gears respectively with change speed gear box on primary annulus and the one-level sun wheel on transmission shaft engagement.
As preferably, the big gear wheel of described dual gear and the number of teeth of miniature gears are respectively 33 and 9.
Further improve, described primary planet carrier is connected with secondary sun wheel on the transmission shaft, and the rotation of primary planet carrier drives the rotation of secondary sun wheel, described secondary planet wheel respectively with secondary sun wheel and change speed gear box on the secondary gear ring mesh.Described secondary planet frame is connected with intermediate gear on being connected in transmission shaft, intermediate gear and cylinder engagement, and the rotation of secondary planet frame drives intermediate gear and rotates, and cylinder also rotates thereupon.
The utility model is owing to adopt dual gear that two-stage planet is merged, can cost-cutting so reduced primary planet carrier and sun wheel, and because of having reduced one-level mechanism, so improved efficient again.
