The model utility content
The purpose of this utility model is to provide a kind of: stability of rotation, rotating accuracy height, the worm and gear Slewing Support Mechanism that volume is little.
The purpose of this utility model is achieved in that this pivoting support comprises double-action variable displacement motor, worm mechanism and pivoting support, there is tooth in the outside of pivoting support, and variable displacement motor is connected with worm mechanism, worm screw is positioned at the pivoting support outside, and worm screw is meshed with pivoting support.
Described double-action variable displacement motor is two double-action variable displacement motors, and specification is identical, is the low-speed big double-action variable displacement motor; Double-action variable displacement motor is connected with worm screw by spline housing.
Described worm mechanism comprises housing, spline housing, bearing, seal ring, outside end cap and drives end cap, housing is two, be positioned at the outer both sides of pivoting support, two housings is 180 degree with respect to the pivoting support center and is fixed on the frame, worm screw by bearing fixing in housing, seal ring is arranged in the bearing outside, on the axle of the end of worm screw, is connected with double-action variable displacement motor, be connected with outside end cap and driving end cap at the two ends of housing respectively by spline housing.
Described pivoting support comprises inner ring and outer ring, on the outer wall of the outer ring of pivoting support the worm gear external tooth is arranged, and inner ring is common pivoting support inner ring; The pivoting support outer ring is fixed on the suspension, and the pivoting support inner ring is fixed on the frame, pivoting support outer ring and suspension bolt.
Beneficial effect owing to adopted such scheme, is processed into the structural type of worm gear with the outer ring of pivoting support, promotes the outer ring revolution of pivoting support by the worm screw of two symmetric arrangement, constitutes the revolving structure that a kind of novel worm and gear drives; Adopt the worm and gear Slewing Support Mechanism, make the pivoting support compact structure, it is little to take up room, and driving torque is big and can realize 360 ° of all-rotation campaigns, is specially adapted to the operating mode of low-speed heave-load.Stability of rotation, rotating accuracy height, volume are little, have reached the purpose of this utility model.
Advantage: the utility model combines turbine with pivoting support, and turbine type is made in the pivoting support outer ring, drives the outer ring revolution of pivoting support by the worm screw of two symmetric arrangement, constitutes a kind of novel worm and gear revolving structure.Characteristics of the present utility model are compact structures, and it is little to take up room, and can easily realize 360 ° of rotation motions, are specially adapted to the operating mode of low-speed heave-load.
