Abstract
The utility model discloses a kind of forestry crane magazins' layout rotary system, comprise turntable sprocket, base body, tooth bar and plain bearing, also comprise tilting bearing and magazins' layout circle, edge on the inner ring that turntable sprocket step is contained in tilting bearing, turntable sprocket root is provided with shaft block ring, plain bearing is arranged on turntable sprocket top, and tilting bearing and plain bearing are all arranged on base body inside, and magazins' layout circle passing hole back-up ring is pressed on self-aligning bearing outer ring.Beneficial effect: turntable sprocket bottom tilting bearing belongs to antifriction-bearing box, and its frictional heating in turning course is little, can also cushion beating and other errors of turning course generation, adapt to high speed of revolutions demand; Tilting bearing can replace the use of plain bearing and thrust bearing two kinds of bearings, and trouble point tails off; The magazins' layout circle increased, can separate the multiple impurity that can damage bearing, and then avoids impurity to damage bearing, protects rotary system, improves pivotal reliability.
Description
Technical field
The utility model relates to a kind of rotary system, is specifically related to a kind of forestry crane magazins' layout rotary system.
Background technology
Forestry crane is a kind of special lorry-mounted crane.Forestry crane can be divided into forestry purposes and industrial use by its purposes, but no matter be applicable to forestry exploitation or for the collection of industrial waste goods and materials and transhipment, forestry crane all needs very fast operating speed, and working environment mostly in the wild or the very severe region of operating mode.This just proposes strict requirement to forestry crane rotary system, not only needs very high speed of revolutions, and needs there is high adaptive capacity to bad working environments, also needs the stability of guarantee work and reliability to reduce the number of times of maintenance process simulation.Rotary system, as the chief component of forestry crane, is responsible for the effect of crane rotation, serves simultaneously and supports rotating platform of crane, arm, grabs accessory and by the effect of starting parcel.
Forestry crane is because of the particularity of its target, and speed of revolutions is very high, impacts very large, generally all adopts oil cylinder with gear racks band carry-over bar to drive the rotation of rotary table be connected as a single entity with sprocket.Except turning force is provided by tooth bar, sprocket also needs hoisting crane pedestal provide support power and resist the moment of toppling.Under very large support reaction and power effect of toppling, between pedestal and turntable sprocket, mating part needs very high intensity, also need very excellent lubrication to meet the high speed revolution of sprocket, and this lubrication also needs highly stable, the plurality of impurities not by bad working environments and self generation affects.
As shown in Figure 1, current forestry crane rotary system adopts rack drives, at two positions of sprocket and base into contact, radial direction is all adopt to coordinate with plain bearing, axial location adopts the version dropped on thrust bearing, hoisting crane is carried with thrust bearing, this structure adopts thrust bearing and plain bearing two kinds of bearings in bottom, achieve and support pivotal object, the plain bearing adopted in bottom especially, if lubricant is less, sprocket and plain bearing can wear and tear and aggravate even to burn to death, can not work on.And the multiple composite impurities that abrasive particle impurity, sprocket and antifriction-bearing box that the impurity that the external world enters, sprocket and tooth bar produce produce all can cause the damage of thrust bearing and lower slide bearings.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of forestry crane magazins' layout rotary system, have between base body with turntable sprocket and very high coordinate intensity, also have excellent lubrication to meet the high speed revolution of sprocket, and plurality of impurities can be avoided the impact of system.
To achieve these goals, the technical solution adopted in the utility model is: a kind of forestry crane magazins' layout rotary system, comprise turntable sprocket, base body, tooth bar and plain bearing, also comprise tilting bearing and magazins' layout circle, edge on the inner ring that turntable sprocket step is contained in tilting bearing, turntable sprocket root is provided with shaft block ring, plain bearing is arranged on turntable sprocket top, tilting bearing and plain bearing are all arranged on base body inside, and magazins' layout circle passing hole back-up ring is pressed on self-aligning bearing outer ring.
Further, magazins' layout circle is flake.
Further, magazins' layout circle is low inside and high outside flake.
The beneficial effects of the utility model are: turntable sprocket bottom tilting bearing belongs to antifriction-bearing box, its frictional heating in turning course is little, because of the characteristic of its aligning effect, beating and other errors of turning course generation can also be cushioned, adapt to high speed of revolutions demand; Tilting bearing can replace the use of plain bearing and thrust bearing two kinds of bearings, and trouble point tails off; The magazins' layout circle increased, can separate the multiple impurity that can damage bearing, and then avoids impurity to damage bearing, protects rotary system, improves pivotal reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, tilting bearing; 2, magazins' layout circle; 3, tooth bar; 4, base body; 5, plain bearing; 6, turntable sprocket; 7, hole back-up ring; 8, shaft block ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 2 and 3, this forestry crane magazins' layout rotary system, comprise turntable sprocket 6, base body 4, tooth bar 3 and plain bearing 5, turntable sprocket 6 carries out driving by tooth bar 3 and turns round, also comprise tilting bearing 1 and magazins' layout circle 2, edge on the inner ring that turntable sprocket 6 step is contained in tilting bearing 1, turntable sprocket 6 root is provided with shaft block ring 8, turntable sprocket 6 is fixed by the bearing inner ring of tilting bearing 1 and shaft block ring 8, bearing force is upwards provided to turntable sprocket 6 by bearing inner ring, plain bearing 5 is arranged on turntable sprocket 6 top, on turntable sprocket 6 top by plain bearing 5, the diametral load providing balance to topple power by tilting bearing 1 to turntable sprocket 6 in bottom, it is inner that tilting bearing 1 and plain bearing 5 are all arranged on base body 4, it can meet the load that forestry crane applying working condition produces, and the lubrication of bearing is better, magazins' layout circle 2 passing hole back-up ring 7 is pressed on tilting bearing 1 outer ring, hole back-up ring 7 also serves the effect of fixing tilting bearing 1, magazins' layout circle 2 effectively can be separated the impurity that the external world enters, the abrasive particle impurity that turntable sprocket 6 and tooth bar 3 produce, the composite impurities that turntable sprocket 6 and antifriction-bearing box produce.Magazins' layout circle 2 is positioned at the top of tilting bearing 1 roller raceway, and above-mentioned plurality of impurities can store through the bottom surface of magazins' layout circle 2, concentrates and remove when maintenance.
In order to improve the effect of the utility model removing impurities further, magazins' layout circle 2 is low inside and high outside flake, and impurity is through the inclined-plane of magazins' layout circle 2, and the bottom surface sliding into magazins' layout circle 2 stores, concentrate when maintenance and remove, removing impurities better effects if.
