Abstract
The invention discloses an improved structure of a rotation device, belonging to the technical field of machinery. The improved structure comprises the rotation device, a bolt, adjusting bolts and four adjusting bolt holes, wherein the bolt is arranged in the middle of the rotation device; the four adjusting bolt holes are arranged around and go through the bolt; the bolt is locked in a screwed part of the rotation device; and the adjusting bolts are screwed in the adjusting bolt holes. The improved structure of the rotation device has the beneficial effects that when the rotation device starts to loose, people only need to screw the adjusting bolts without a large-scale wrench, and therefore, unnecessary trouble can be saved. The improved structure of rotation device is simple in structure and convenient to operate.
Description
Technical field
The present invention relates to a kind of slewing gear, specifically is a kind of structure-improved of slewing gear, belongs to field of mechanical technique.
Background technique
The diameter of bolt in the middle of some slewing gears is bigger, if loosening phenomenon appears in slewing gear, need look for and large-scalely pull turn and screw tight, and screws down at powerful torsion, though each parts has been locked, but the difficulty that can cause nut to deviate from produces the puzzlement of adjustment inconvenience.
Summary of the invention
To the problem that above-mentioned existing technology exists, the present invention provides a kind of structure-improved of slewing gear, and is simple in structure, is convenient to operation.
To achieve these goals; The technological scheme that the present invention adopts is: a kind of structure-improved of slewing gear, comprise slewing gear, and be located at the middle bolt of slewing gear; Also comprise the adjustment screw rod; And the adjustment screw that is located at four perforations of bolt periphery, bolt is locked on the screwing part of slewing gear, and the adjustment screw rod screws in the adjustment screw.
The invention has the beneficial effects as follows: when slewing gear occurs becoming flexible phenomenon, need not to look for again large-scale spanner turn to screw tight, only need turn adjustment screw rod to get final product, omitted unnecessary trouble, and simple in structure, be convenient to operation.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention
Among the figure: 1, slewing gear, 2, the adjustment screw, 3, the adjustment screw rod, 4, bolt, 5, screwing part.
Embodiment
To combine accompanying drawing that the present invention is described further below.
As shown in Figure 1; A kind of structure-improved of slewing gear comprises slewing gear 1, is located at the bolt 4 of slewing gear 1 centre; Also comprise adjustment screw rod 3; And the adjustment screw 2 that is located at four perforations of bolt 4 peripheries, bolt 4 is locked on the screwing part 5 of slewing gear 1, and adjustment screw rod 3 screws in adjustment screw 2.
