Abstract
The invention discloses a kind of slewing equipment for heavy duty transporter, including worm gear, worm transmission pair and slewing bearing；Slewing bearing is arranged in toroidal shell, worm gear gear ring by cast tin bronze material into and be embedded in the outer ring side face of slewing bearing；The barrel-type casing for installing worm screw is fixed with the side wall of toroidal shell, by roller bearings on the barrel-type casing, one end of worm screw is extended to be connected worm screw outside barrel-type casing with the pto of planetary reduction gear；The power input shaft of planetary reduction gear is connected with hydraulic motor or electric-motor drive；Nut hole is uniformly offered on slewing bearing inner ring, through hole is offered corresponding to the nut hole location on toroidal shell；Uniformly offer the screw for connecting pivoting part vertically on slewing bearing outer ring.The present invention not only increases gearratio and output steering torque, while structure is simpler and more direct, compact, small volume.
Description
Technical field
The present invention relates to speed reducing rotation device, the slewing equipment of heavy duty transporter is especially for.
Background technology
The slewing equipment of heavy duty transporter is presently used for, it is typically by single cylinder and straight using brace and connecting rod framework form
Tape splicing moves pivoting support and realizes steering, and steering torque is provided by oil cylinder.The steering angle of above-mentioned slewing equipment depends on oil cylinder
The length of piston rod, when requiring that steering angle is big, cylinder piston rod must just lengthen, and cause whole steering mechanism with being arranged
For the sufficiently bulky of upper occupancy, it is therefore necessary to corresponding increase equipment overall volume.Meanwhile determined by its drive mechanism characteristic,
Pivoting support is in non-uniform rotation state all the time, therefore has that to turn to that stationarity is poor, living load is uneven, efficiency is low etc. scarce
Fall into.Especially because brace and connecting rod framework has dead angle in itself, maximum angle of revolution is less than ± 90 °, causes above-mentioned slewing equipment to be fitted
It is very limited with scope, it is impossible to which in angle of revolution, larger occasion uses.
The content of the invention
Present invention aims at provide a kind of compact-sized, small volume, output torque big time for being used for heavy duty transporter
Rotary device.
To achieve the above object, the present invention takes following technical proposals：
Slewing equipment of the present invention for heavy duty transporter, including worm gear, worm transmission pair and slewing bearing；It is described
Slewing bearing is arranged in toroidal shell, and the worm gear, the worm gear gear ring of worm transmission pair are by cast tin bronze material, casting
Gunmetal, casting tin nickel bronze, casting Al-Fe bronze or cast aluminium iron nickel bronze material is made to be made and be embedded in revolving support axle
The outer ring side face held；The barrel-type casing for installing worm screw is fixed with the side wall of the toroidal shell, the worm screw passes through
Roller bearings on the barrel-type casing, extend defeated with the power of planetary reduction gear outside barrel-type casing by one end of worm screw
Shaft is connected；The power input shaft of the planetary reduction gear is connected with hydraulic motor or electric-motor drive；In revolving support
Nut hole is uniformly offered on bearing inner race, through hole is offered corresponding to the nut hole location on toroidal shell；Returning
Turn uniformly to offer the screw for connecting pivoting part on spring bearing outer ring vertically.
The worm gear, worm transmission pair use double enveloping worm gearing or Property of Plane-enveloped Worm Transmission or involute
Double enveloped hourglass worm drives structure.
The present invention thoroughly solves existing oil cylinder steering mechanism steering and angle be present as a result of worm gear, worm screw auxiliary driving
The shortcomings that degree limitation so that angle of revolution is more than 360 °；Worm gear, worm gear pair type of belt drive employ enveloping worm drive, significantly
Improve bearing capacity and transmission efficiency；Worm screw is connected with hydraulic motor or electric-motor drive by planetary reduction gear, not only
Gearratio and output steering torque are increased, while make it that structure is simpler and more direct, compact, small volume, it may also be used for miscellaneous equipment
Steering.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is Fig. 1 A-A to face view.
Fig. 3 is Fig. 2 I portions enlarged drawing.
Embodiment
As shown in Figure 1, 2, 3, the slewing equipment of the present invention for heavy duty transporter, including worm gear, worm transmission pair
And slewing bearing；The slewing bearing is arranged in toroidal shell 1, the worm gear, the worm-gear toothing of worm transmission pair
Circle 2 is made up of cast tin bronze material and is embedded in the side face of outer ring 3 of slewing bearing, to solve because similar metal material is deposited
Engaging tooth is caused the generation of glued phenomenon occur in affinity；It is fixed with the side wall of the toroidal shell 1 for installing
The barrel-type casing 5 of worm screw 4, by roller bearings on the barrel-type casing 5, the other end of worm screw 4 extends the worm screw 4
Go out the pto outside barrel-type casing 5 with planetary reduction gear 6 to be connected；The power input shaft of the planetary reduction gear 6
It is connected with hydraulic motor or motor 7；Nut hole 9 is uniformly offered vertically on slewing bearing inner ring 8, in annular
On housing 1 through hole 10 is offered corresponding to the opening position of nut hole 9；Uniformly opened vertically on slewing bearing outer ring 3
Provided with the screw 11 for connecting pivoting part.In the case where not increasing transmission parts volume conditions, further to improve bearing capacity
And transmission efficiency, worm gear, worm transmission pair use double enveloping worm gearing or Property of Plane-enveloped Worm Transmission or involute
Double enveloped hourglass worm drives structure.
