Abstract
The utility model relates to a speed reduction mechanism for a portable capstan, belonging to the common component of the forestry machinery, comprising: a dual articulated gear is equipped on two bearings, and the two bearings are equipped on an eccentric axis; one annular gear is fixed on a bracket by a bolt, and the other annular gear is connected with a reel drum by the bolt. When working, the dual articulated gear conducts autorotation and revolution at the same time under the driving of the eccentric axis; the annular gear which is connected with the reel drum is driven to gyre, and the reel drum gyres at the same time, and thus operation can be proceed. The utility model can be widely used for the portable capstan for the operation of the forest-area felling skidding and the city architecture, etc.
Description
The utility model belongs to the general parts of forestry machinery.
The speed reduction gearing of general portable capstan engine adopts an independent drop-gear box, and this apparatus structure complexity, reel stressing conditions are bad, and tractive force is little.
The purpose of this utility model provides a kind of and reel and is one, simple in structure, the reel stressing conditions is good, tractive force is big portable capstan engine speed reduction gearing.
Basic structure pattern of the present utility model is by a planet circular system and the compound epicyclic train that differential gear train is formed.This device comprises: a dual gear is installed on two bearings, and this two bearing installation is on eccentric shaft, and an inner gear is by being bolted on the support, and another inner gear is linked together by bolt and reel.Dual gear is two inner gear engagements therewith simultaneously.
The said apparatus principle of work is as follows:
1, dual gear on the one hand around the eccentric axis rotation, revolves round the sun around the eccentric shaft spindle axis again under the driving of eccentric shaft simultaneously.
2 and the inner gear that is linked together of reel in the engagement of dual gear, be with reel to turn round, and the inner gear that is fixed on the support maintains static.
3, by changing dual gear, two inner geares, device has variable-speed ratio.
Owing to adopted compound epicyclic train, portable capstan engine of the present utility model with speed reduction gearing and reel be one, simple in structure, the reel stressing conditions is good, tractive force is big, can be widely used in the forest zone and fell the portable capstan enginees of operation such as logging, urban architecture.
Accompanying drawing is a portable capstan engine speed reduction gearing general assembly section-drawing.
The utility model embodiment is as follows:
As shown in drawings, portable capstan engine comprises with speed reduction gearing: a dual gear (5) is installed on two bearings (7), this two bearing (7) is installed on the eccentric shaft (1), an inner gear (4) is fixed on the support (6) by bolt (8), and another inner gear (3) is linked together by bolt (9) and reel (2).Dual gear (5) meshes with two inner geares (3), (4) simultaneously.During work, dual gear (5) is under the driving of eccentric shaft (1), one side is around the eccentric axis rotation, simultaneously the inner gear (3) that is linked together around the revolution of eccentric shaft spindle axis and reel (2) again can carry out operation being with reel (2) to turn round in the engagement of dual gear (5).
It is that change by dual gear (5), two inner geares (3), (4) number of teeth obtains that the transmitting ratio of this device changes.Concrete grammar can be realized by directly changing different dual gear (5) and two inner geares (3), (4) of the number of teeth.
Claims (1)
1, portable capstan engine speed reduction gearing, it is characterized in that, having a dual gear (5) is installed on two bearings (7), this two bearing (7) is installed on the eccentric shaft (1), an inner gear (4) is fixed on the support (6) by bolt (8), another inner gear (3) is linked together by bolt (9) and reel (2), and dual gear (5) meshes with two inner geares (3), (4) simultaneously.
