Abstract
The utility model relates to a novel duplex-gear slewing mechanism. A motor provides input power; a shaft sleeve of the motor drives a primary sun gear by the aid of a transmission shaft; the primary sun gear is connected with a primary planetary gear; the primary planetary gear meshes with a primary inner gear ring; the primary planetary gear adopts duplex gears; a primary planet carrier is connected with a secondary sun gear; the secondary sun gear meshes with a secondary planetary gear; the secondary planetary gear meshes with a secondary inner gear ring; a secondary planet carrier is connected with a tail-end output shaft; and the tail-end output shaft is provided with a gear meshing with a slewing bearing. A plurality of parts of the novel duplex-gear slewing mechanism are integrated, so that the mechanism is more compact and reasonable and smaller in volume. The primary planetary gear adopts the duplex gears, so that reduction ratio is increased and output torque is improved within strength allowed by the mechanism. For some slewing mechanisms of specific types, three-stage transmission is even converted into two-stage transmission, and accordingly the volume and the weight of the mechanism is decreased more, so that the mechanism is more compact, and cost is reduced.
Description
Technical field
The utility model relates to a kind of mechanical transmission structure, specifically, relates to a kind of swirl gear of planetary pinion transmission.
Background technique
The operation that engineering machinery such as excavator, hoist, concrete mixer all have corresponding jib to be scheduled to; But also need concern according to the difference adjustment jib of work surface position and the position of chassis or underframe.Jib adjustment for convenience generally is provided with swirl gear, so that jib can rotate with respect to chassis or underframe in 360 degree scopes between jib and chassis or underframe.In addition, in Other Engineering machinery or equipment, also be provided with swirl gear, to realize the relative adjustment of suitable component locations.The planetary pinion swirl gear is a kind of general transmission component, is widely used in hoist, excavator, transportation, building, boats and ships, wind-powered electricity generation etc. mechanically.Existing swirl gear volume is big, Heavy Weight, structure is compact inadequately, cost is high.
The model utility content
The utility model is big at existing swirl gear volume, Heavy Weight, structure problems such as compactness, cost height inadequately, propose that a kind of volume is little, in light weight, compact structure, driving power greatly, the planetary pinion swirl gear of good airproof performance.
The technical solution of the utility model is: a kind of novel duplicate gear swirl gear, provide input power by motor, the axle sleeve of described motor drives first order sun gear by transmission shaft, and first order sun gear is connected with first order planet wheel, first order planet wheel and the engagement of first order ring gear; Described first order planet wheel adopts duplicate gear; First order planet carrier connects second level sun gear, second level sun gear and the engagement of second level planet wheel, and second level planet wheel and the engagement of second level ring gear, second level planet carrier connects terminal output shaft, and terminal output shaft has gear and pivoting support engagement.
The beneficial effects of the utility model are: because a lot of parts of the present utility model become one, so mechanism's compact and reasonable more, volume is littler; First order planet wheel has adopted duplicate gear, in the intensity that mechanism allows, has increased reduction speed ratio, has improved output torque.To the swirl gear of some specific model, even converted the secondary transmission to, thereby the bigger volume and weight that has reduced mechanism makes mechanism more compact, has reduced cost by three grades of transmissions.In addition, the utility model also have moment of torsion big, drive that power is big, good airproof performance, low cost and other advantages.The utility model can be widely used in hoist, excavator, transportation, building, boats and ships and wind-powered electricity generation etc. mechanically.
