Abstract
The utility model discloses a rotary device for a heavy flat car. The rotary device comprises a worm gear, a worm transmission pair and a rotary supporting bearing, wherein the rotary supporting bearing is arranged in an annular shell body, a worm gear ring is made from tin bronze through casting and embedded on the circumferential face of the outer ring of the rotary supporting bearing, the side wall of the annular shell body is fixedly connected with a barrel-shaped shell body used for installing a worm, the worm is supported on the barrel-shaped shell body through a rolling bearing, one end of the worm extends out of the barrel-shaped shell body and is connected with a power output shaft of a planetary reducer in a transmission mode, and a power input shaft of the planetary reducer is in transmission connection with a hydraulic motor or an electromotor. Bolts holes are evenly formed in the inner ring of the rotary supporting bearing, and through holes are formed in positions, corresponding to the bolt hole positions, of the annular shell body. Screw holes used for connecting rotary components are uniformly formed in the outer ring of the rotary supporting bearing along the axial direction. The rotary device increases a transmission ratio and an output steering torque, meanwhile, the structure is simple and compact, and the size is small.
Description
Technical field
The utility model relates to the deceleration turning gear, especially relates to the turning gear that is used for heavy flat truck.
Background technology
At present, be used for the turning gear of heavy flat truck, normally by single oil cylinder and adopt the brace and connecting rod framework form directly to drive pivoting support and realize turning to, provide steering torque by oil cylinder.The steering angle of above-mentioned turning gear depends on the length of oil cylinder piston bar, and when requiring steering angle big, the oil cylinder piston bar just must extend, and the volume that causes whole steering hardware to take on corollary equipment is very big, therefore must corresponding increase equipment integral volume.Therefore simultaneously, determined that pivoting support is in non-uniform rotation state all the time, had defective such as turn to that stationarity is poor, living load inequality, efficient are low by its drive mechanism characteristic.Particularly, can not use in the big occasion of degreeof turn because there is the dead angle in brace and connecting rod framework itself, and maximum angle of revolution causes above-mentioned turning gear Applicable scope to be very limited less than ± 90 °.
Summary of the invention
The utility model purpose is to provide a kind of compact conformation, volume is little, output torque the is big turning gear that is used for heavy flat truck.
For achieving the above object, the utility model is taked following technical proposals:
The turning gear that is used for heavy flat truck described in the utility model comprises worm gear, worm transmission pair and slewing bearing; Described slewing bearing is arranged in the annular casing, and the outer ring side face of slewing bearing made and be embedded in by the worm gear gear ring of described worm gear, worm transmission pair by cast tin bronze material, casting gunmetal, casting tin nickel bronze, casting ampco or cast aluminium iron nickel bronze material; Be fixed with the barrel-type casing that is used to install worm screw on the sidewall of described annular casing, on described barrel-type casing, the power take-off shaft that the end of worm screw extends outside the barrel-type casing with planetary reduction gear is in transmission connection described worm screw by roller bearings; The power input shaft of described planetary reduction gear is connected with HM Hydraulic Motor or electric motor drive; The uniform nut hole that offers on the slewing bearing inner ring offers through hole corresponding to place, described nut hole site on annular casing; The uniform vertically screw that is used to connect pivoting part that offers on the slewing bearing outer ring.
Described worm gear, worm transmission pair adopt hindley worm transmission or planar double enveloping worm transmission or involute double enveloping worm drive mechanism.
The utility model has thoroughly solved existing oil cylinder steering hardware and has turned to the shortcoming that has angle limits owing to adopted worm gear, worm couple transmission, makes degreeof turn greater than 360 °; Worm gear, worm couple type of belt drive have adopted the enveloping worm transmission, have improved load-carrying capacity and driving efficiency greatly; By planetary reduction gear worm screw is connected with HM Hydraulic Motor or electric motor drive, has not only increased transmitting ratio and output steering torque, make that simultaneously structure is simpler and more direct, compact, volume is little, also can be used for turning to of miscellaneous equipment.
