The specific embodiment
Below will be described in further detail the utility model motorcar electric capstan winch.
As illustrated in fig. 1 and 2, this motorcar electric capstan winch comprises electrical motor 1, planetary gear speed reducing mechanism, winding drum 14 and steel rope 23.Electrical motor 1 drives planetary gear speed reducing mechanism, and planetary gear speed reducing mechanism drives winding drum 14 and goes up steel rope 23.Described planetary gear speed reducing mechanism comprises: deceleration box 3, centre tooth 2, a plurality of planet tooth 5, quiet gear ring 4, moving gear ring 8 and planetary gear speed reducing mechanism output shaft 12.Wherein, quiet gear ring 4 is installed in the deceleration box 3, centre tooth 2 is captiveed joint with motor output shaft, and centre tooth 2 respectively with 5 engagements of each planet tooth, each planet tooth 5 is captiveed joint with planetary gear speed reducing mechanism output shaft 12 with moving gear ring 8 engagements and moving gear ring 8 with quiet gear ring 4 respectively.Described planet tooth 5 is nested with rotatably on compensating-gear shaft 6, described planet tooth 5 and be provided with two bearings that are used to support 7 separately between the compensating-gear shaft 6.Each compensating-gear shaft 6 is captiveed joint with deceleration box 3.
The utility model is work like this: electrical motor 1 drives centre tooth 2 and rotates.Described centre tooth 2 is commonly called as sun wheel, and it drives planet tooth 5 and rotates in quiet gear ring 4, and the moving gear ring 8 of each planet tooth 5 drive rotates simultaneously.Described moving gear ring 8 is captiveed joint with planetary gear speed reducing mechanism output shaft 12.Planetary gear speed reducing mechanism output shaft 12 herein is the plum blossom tooth assembly.Described plum blossom tooth assembly 12 is also captiveed joint with the axle of winding drum 14.Therefore, moving gear ring 8 can drive winding drums 14 by plum blossom tooth assembly 12, and then the steel rope 23 tractive vehicles or other objects that are driven on it by winding drum 14.
As shown in Figure 3, because the thickness of planet tooth 5 is wideer than bearing 7, therefore, it is more steady to need two bearings 7 to support planet tooth 5.Because planet tooth 5 adopts duplex bearing 7 supportings, each planet tooth 5 is stressed even, and not easy to wear, the life-span is long.
Described planet tooth 5 has three.Common three planet teeth 5 can reach required reduction ratio.
Described moving gear ring 8 is an embedded structure, and it is embedded in the deceleration box 3, and is meshed with each planet tooth 5.Better reliability when therefore, moving gear ring 8 transmissions.
Described quiet gear ring 4 and moving gear ring 8 adopt ductile cast iron material.Therefore, has the intensity height, wear-resistant advantage.
Generally speaking, the utility model is simple in structure, and is practical and convenient. Owing between planet tooth and axle, adopt Duplex bearing supported, therefore, each planet tooth is stressed evenly, and is not easy to wear, thereby the life-span is longer. Because moving tooth Circle adopts embedded structure, so its better reliability. In addition, moving gear ring and quiet gear ring adopt spheroidal graphite cast-iron Replace original casting aluminium material, therefore, have intensity height, wear-resistant advantage.
