Abstract
The utility model relates to a high-altitude operation vehicle, in particular to a rotary speed reduction device with an adjustable central moment. The rotary speed reduction device belongs to the technical field of machining and comprises a rotary table. A rotary speed reducer and motor is fixed on the rotary table by a third bolt, the outer ring of a rotary bearing is fixed on a subframe structure by a second bolt, and the inner ring of the rotary bearing is fixed on the rotary table by a first bolt; an eccentricity adjustment ring is arranged between the rotary table and the rotary speed reducer and motor; and the eccentricity adjust ring is fixed on the side surface of the rotary table by a fourth bolt. The size of the central moment of the rotary speed reducer and the rotary bearing can be adjusted by the eccentricity adjustment ring, therefore backlash deviation arising from self-manufacturing error and mutual abrasion of the rotary speed reducer and the rotary bearing, and machining error of positioning holes on the rotary table is eliminated so as to obtain an ideal backlash.
Description
Technical field
The utility model relates to a kind of high-altitude operation vehicle, is specifically related to the adjustable slewing reduction apparatus of a kind of high-altitude operation vehicle central moment, belongs to the Machining Technology field.
Background technique
The swirl gear of high-altitude operation vehicle assembles at the scene and moves after a period of time, because foozle and wearing and tearing between rotary reducer and the pivoting support, thereby cause both back lashes to become big, this just need adjust swirl gear central moment.At present, the technology of the adjustment gyration center square that is had, not only being limited in scope of adjustment, and the mode of adjusting is not quite reasonable, adjustment is got up very inconvenient, can not reach the perfect condition of wanting sometimes.
Summary of the invention
The utility model purpose is for overcoming above-mentioned the deficiencies in the prior art part, provide a kind of central moment adjustable slewing reduction apparatus, being made up of turntable, pivoting support, rotary reducer, eccentric adjustment ring.The eccentric adjustment ring of an inside and outside circle decentraction is set between turntable and rotary reducer, rotate the central moment size that the eccentric adjustment ring can be regulated rotary reducer and pivoting support, can eliminate because the foozle of rotary reducer, pivoting support self and mutually wearing and tearing with and the back lash deviation brought of the machining error of positioning hole on turntable, to obtain desirable back lash.
The utility model is realized with following technological scheme: the slewing reduction apparatus that a kind of central moment is adjustable, this device includes turntable, by the 3rd bolt rotary reducer and motor are arranged on the turntable, the outer ring of pivoting support is bolted on the subframe structure by second, the inner ring of pivoting support is bolted on the turntable by first, it is characterized in that: an eccentric adjustment ring is set between described turntable and rotary reducer and the motor, and described eccentric adjustment ring is by the 4th side that is bolted to turntable.
The eccentric adjustment ring that described eccentric adjustment ring is an inside and outside circle decentraction.
The utility model has the advantages that: this slewing reduction apparatus is provided with the eccentric adjustment ring of an inside and outside circle decentraction between turntable and rotary reducer, rotate the central moment size that the eccentric adjustment ring can be regulated rotary reducer and pivoting support, can eliminate because the foozle of rotary reducer, pivoting support self and mutually wearing and tearing with and the back lash deviation brought of the machining error of positioning hole on turntable, to obtain desirable back lash.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is a structural drawing of the present utility model:
Fig. 2 is the plan view of Fig. 1:
Among the figure: 1, subframe structure, 2, turntable, 3, first bolt, 4, pivoting support, 5, second bolt, 6, rotary reducer and motor, the 7, the 3rd bolt, 8 eccentric adjustment rings, the 9, the 4th bolt.
Embodiment
With reference to Fig. 1, Fig. 2: the slewing reduction apparatus structure that central moment is adjustable as shown in Figure 1, the outer ring of pivoting support 4 is fixed on the subframe structure 1 with second bolt 5, the inner ring of pivoting support 4 is fixed on the turntable 2 with first bolt 3, can unrestrictedly turn round continuously between the inside and outside circle of pivoting support.Eccentric adjustment ring 8 usefulness tightenings the 4th bolt 9 is fixed on the turntable 2.Rotary reducer and motor 6 usefulness the 3rd bolt 7 are fixed on the turntable 2.Fixed gear ring engagement on the output pinion of rotary reducer and the pivoting support outer ring, the rotation of output pinion, driving rotational supporting inner ring reaches with top, rotates with respect to the pivoting support outer ring.
When regulating eccentric adjustment ring 8, eccentric adjustment ring 8 drives rotary reducer and motor 6 moves, thereby realizes the regulating tooth side clearance, and is fixing with the 4th bolt 9 during position suitable, promptly finishes the adjustment of central moment.
