Abstract
The utility model relates to an oil leakage-resisting hydraulic swivel joint which is characterized by comprising a swiveling body (1) and a swiveling shaft (2), wherein the bottom end of the swiveling shaft (2) is axially inserted into the swiveling body (1) from the top end of the swiveling body (1), the top end of the swiveling shaft (2) extends beyond the swiveling body (1), a dustproof sleeve (10) is sleeved around the periphery of the gap between the top end of the swiveling body (1) and the swiveling shaft (2), and a dustproof loop (11) is arranged between the lower end of the dustproof sleeve (10) and the swiveling body (1). The oil leakage-resisting hydraulic swivel joint is advantageous in that after the dustproof sleeve is used in combination with the dustproof loop, the outside dust does not easily get into the swiveling joint, the oil can be prevented from leaking from the inside, and therefore the performance of the swiveling joint is guaranteed.
Description
Technical field
The utility model relates to a kind of hydraumatic swivel joint of not easy oil leakage, is mainly used in belonging to technical field of engineering machinery in the hydraulic system of crawler excavator.
Background technique
Up and down two-part of crawler excavator are need to be rotating, connect by swivel coupling in the middle of it.Swivel coupling is comprised of solid of rotation, turning axle and lid etc.During use, the revolution lower bolster of solid of rotation and crawler excavator is fixed, and the mounting plate on the turning axle supports with the revolution of crawler excavator and is connected, and up and down two-part of crawler excavator are finished by solid of rotation and turning axle and relatively rotated.
Yet swivel coupling in the past is relatively poor with extraneous sealability, extraneous dust easily creeps in the swivel coupling, affected the performance of swivel coupling, and the oil in the swivel coupling spills easily also, solid of rotation in the swivel coupling and turning axle are relatively rotated also produced impact.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of dust to be difficult for entering, and oil is difficult for spilling, and solid of rotation and turning axle relatively rotate the hydraumatic swivel joint of impregnable not easy oil leakage.
The purpose of this utility model is achieved in that
The hydraumatic swivel joint of not easy oil leakage of the utility model, comprise solid of rotation and turning axle, insert from the top axial of solid of rotation the bottom of described turning axle, the top of described turning axle is exposed to solid of rotation, described solid of rotation links to each other by cover plate with the bottom of turning axle, the bottom of described turning axle oilhole is vertically arranged with cone blocking, be provided with O type circle I between cover plate and the cone blocking, be provided with shaft block ring and back-up ring between the lower end of described solid of rotation and the lower end of turning axle, also be provided with rotating seal ring and O shape circle II between described solid of rotation and the turning axle, the top of described solid of rotation and the slit outer race between the turning axle have dirt-proof boot, are provided with dust ring between the lower end of described dirt-proof boot and the solid of rotation.
Compared with prior art, the beneficial effects of the utility model are:
The hydraumatic swivel joint of this not easy oil leakage has been set up a dirt-proof boot between solid of rotation and turning axle, dirt-proof boot encases dirt-proof boot, after being used in conjunction with, this dirt-proof boot and dust ring can make extraneous dust be difficult for creeping in the swivel coupling, and oil can not spill internally, thereby has guaranteed the performance of swivel coupling.
Description of drawings
Fig. 1 is the sectional view of the hydraumatic swivel joint of not easy oil leakage of the utility model.
Wherein: solid of rotation 1, turning axle 2, cover plate 3, cone blocking 4, O type circle I 5, shaft block ring 6, back-up ring 7, rotating seal ring 8, O shape circle II 9, dirt-proof boot 10, dust ring 11.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of hydraumatic swivel joint of not easy oil leakage, comprise solid of rotation 1 and turning axle 2, insert from the top axial of solid of rotation 1 bottom of described turning axle 2, the top of described turning axle 2 is exposed to solid of rotation 1, described solid of rotation 1 links to each other by cover plate 3 with the bottom of turning axle 2, the bottom of described turning axle 2 oilholes is vertically arranged with cone blocking 4, be provided with O type circle I 5 between cover plate 3 and the cone blocking 4, be provided with shaft block ring 6 and back-up ring 7 between the lower end of the lower end of described solid of rotation 1 and turning axle 2, also be provided with rotating seal ring 8 and O shape circle II 9 between described solid of rotation 1 and the turning axle 2, slit outer race between the top of described solid of rotation 1 and the turning axle 2 has dirt-proof boot 10, be provided with dust ring 11 between the lower end of described dirt-proof boot 10 and the solid of rotation 1, after dirt-proof boot 10 and dust ring 11 are used in conjunction with the slit between solid of rotation 1 and the turning axle 2 is encased fully, thereby so that extraneous dust is difficult for creeping in the swivel coupling, and oil can not spill internally, thereby guaranteed the performance of swivel coupling, need not often to oil, reduced workman's labor intensity.
