Abstract
The utility model relates to a fully lubricated and high sealing crane tube steering knuckle which relates to the technology of the crane tube steering. Because the existing steering knuckle has the disadvantages of poor seal, water seepage, oil leakage, easy corrosion in steering parts and poor steering mobility, the utility model discloses the fully lubricated and high sealing crane tube steering knuckle which comprises a tube seat of a steering tube, a locked nut, a steering knuckle main unit, upper and lower plane rolling balls, a pressure adjusting nut, a locking nut and the steering tube, wherein the steering tube is provided with a screw thread press cover, a sealing filler, a screw thread press cap and a sealing ring from top to bottom. The bottom is provided with a lower plane rolling ball moving disc; the inner wall of the steering knuckle main unit is provided with upper and lower plane rolling ball static discs, and the outer wall is provided with a hole which is communicated with an inner cavity and a hole internal thread plug; a slot-shaped elastic sealing ring is arranged between the steering tube and the tube seat of the steering tube; the sealing filler is arranged between the locked nut and the steering knuckle main unit. The outer surface of the locking nut is provided with a rolling needle which is matched with the inner wall of the steering knuckle main unit. The steering knuckle has the advantages of no water seepage, no oil leakage, stable rotating center, flexible steering and long service life.
Description
Technical field
The utility model relates to and needs the knuckle, the particularly crane tube steering journal about using in the loading and unloading arm that turn to relatively in a kind of conveyance fluid device.
Background technique
At present, the knuckle that uses in the loading and unloading arm, it includes by the steering tube base, and the knuckle inner chamber that coupled locking nut and knuckle main part are formed is equipped with steering tube, plane ball, look nut and locking nut from the bottom to top successively in the chamber.Feel in the practicality: be located at the O RunddichtringO between steering tube and the steering tube base, poor flexibility, hard contact, wearing and tearing are big, easy oil leakage; Steering tube and look nut, locking nut threaded connection place, knuckle main part and steering tube base threaded connection place, locking nut and knuckle main part matching gap place do not have sealing, and rainwater usually infiltrates in the knuckle inner chamber; Inject the lubricating grease trouble in the chamber, use easily agingly for a long time, the cold-weather lubrication effect is particularly bad, if during drip-feed lubricating oil, usually takes place lubricated not in placely, and leakiness causes lubricated badly, influence rotating effect, reduction working life; Locking nut and the knuckle main part gap that is slidingly matched is big, under the oil filling riser action of gravity, the turning center displacement, more than all multifactor plane balls, pearl frame of causing perishable, increase abrasion, influence rotating effect, often need maintaining, oiling, increase operating cost.
Summary of the invention
For overcoming above-mentioned deficiency, it is stable that the utility model is intended to disclose a kind of turning center, tightly-sealed, do not ooze rainwater, the whole oil immersions in movable position, resistance to corrosion is strong, friction is little between surface of contact, but level, the vertical use are simple in structure, rotate light complete lubricated high sealing crane tube steering journal freely.
The technological scheme that its technical problem that solves the utility model adopts is: it includes by the steering tube base, the knuckle inner chamber that coupled locking nut and knuckle main part are formed, steering tube is housed in the chamber from the bottom to top successively, the plane ball, look nut and locking nut, wherein in steering tube upper end successively to having the union (screwed)bonnet (UB that is used to seal, stuffing box packing, union cap (UC) and seal ring, form the bearing type motion structure for making knuckle main part and steering tube, knuckle main part inwall is provided with the quiet dish of plane ball, the quiet dish of lower plane ball, the steering tube bottom is provided with lower plane ball Moving plate, be provided with between steering tube base and the steering tube and can accept the flute profile elastic seal ring that hydrodynamic pressure increases sealing intensity automatically, be provided with stuffing box packing between locking nut and the knuckle main part, knuckle main part tube wall is provided with hole that communicates with oil pocket and the plug that mates with the hole, is provided with the needle roller that prevents the displacement of steering tube center of rotation between the locking nut outside and the knuckle main part inwall.
The beneficial effects of the utility model are: the turning center invariant position, and good seal does not seep water, oil-proof, the whole immersion oil in movable position, anti-corrosion capacity is strong, friction is little between the movable part surface of contact, rotate light and flexible, suitable level, vertically install and use the deduction and exemption maintaining, simple in structure, easy to assembly, easily processing, long service life.
Description of drawings
