Abstract
The utility model provides a alluvial gold ship carrier roller of passing a bridge, characterized by have two on the cylinder body of slide bearing both sides and revolve to opposite spiral, the equal directional slide bearing of thrust that this spiral produced, the ring channel of installing the sealing washer still has on the cylinder body, the tank bottom all has the spiral with the interior disc from the tank bottom to the cylinder body outer end, this spiral and sealing washer constitute spiral dynamic seal and sealing washer static seal respectively. The structure ensures that the carrier roller has good sealing effect when working or being static, and two reverse screws are adopted to forcibly apply pressure oil to the sliding bearing, so that the abrasion between the sliding bearing and a friction surface is greatly reduced.
Description
The utility model relates to a kind of gap bridge carrying roller of adopting gold dust with ship, and the gold dust ship that is suitable for all size uses at 8-20 rice under-water operation.
The gap bridge carrying roller of existing gold dust ship, its hermetically-sealed construction mainly adopts the forms such as oil sealing, floating ring or labyrinth of all kinds of routines, because severe jolt and phenomenons such as bucket chain rapping and bucket chain sideslip that the geographical conditions of underwater complex are given birth to the gold dust ship, all can cause the axial motion of carrying roller, thereby be easy to destroy this class hermetically-sealed construction.Extremely slow because of the carrying roller rotating speed again, make plain bearing inside not form effective oil film, thereby its serious wear, generally have only about 2 to 3 months service life.
Have the shortcoming that leak tightness is poor, service life is short at existing gold dust ship gap bridge carrying roller, the purpose of this utility model is to provide a kind of and can effectively seals, and can form the novel gold dust ship gap bridge carrying roller of forcing oil film to plain bearing again simultaneously.
The purpose of this utility model is achieved in that on the barrel of plain bearing both sides and is respectively arranged with two spirals that rotation direction is opposite, the thrust that this spiral produces with barrel rotation with oil pressure to plain bearing, force plain bearing to separate with friction face, also has circular groove on the barrel, this circular groove matches with the boss that axle sleeve has, the circular groove side is equipped with seal ring, also have spiral on the inner headed face from bottom land to the barrel outer end, this spiral and circular groove bottom surface spiral all with barrel on seal ring constitute spiral dynamic seal and seal ring static seal.
Barrel circular groove side also has the cover of adjustment.
Have filler port in the barrel, oilhole one tunnel communicates with oil pocket, and another road is equipped with check valve and communicates with annular groove on the barrel.
The utility model is owing to adopted the structure of spiral dynamic seal and seal ring static seal, make carrying roller in work or all have good sealing effectiveness when static, adopt two reverse screws that plain bearing is forced to exert pressure oil, the wearing and tearing of plain bearing and friction face are reduced greatly, thereby the utlity model has sealing reliably, survivable and wearing and tearing, the advantage of long service life.
Below in conjunction with accompanying drawing the utility model and embodiment are elaborated:
Accompanying drawing is the utility model part-structure cutaway view.
Referring to accompanying drawing: by supporting base 1, axle 2, locating piece 3, axle sleeve 4, plain bearing 5, seal ring 6,7 and barrel constitute.For ease of making and installing, this barrel is divided into cylinder 8, screw-casing 17(should put has spiral 9) and flange 10,11 4 is partly.Inner headed face on the flange 10 has the spiral 12 of two different radiis, 13, plain bearing 5 is limited between the step of flange 10 and axle 2, plain bearing 5 one sides have the spiral 12 on the flange 10, opposite side has the screw-casing 17 that is installed on the cylinder 8, spiral 9,12 is reverse screw, the thrust of its generation is all pointed to plain bearing 5, and the thrust that spiral 9 produces is greater than the thrust of spiral 12, flange 10 is fixed on cylinder 8 one ends, flange 11 is fixed together with flange 10 again, the spiral 14 that also has two different radiis on the inner headed face of flange 11,15, and spiral 13,14 lump together the spiral that constitutes barrel circular groove bottom surface, the circular groove side is a flange 10, be fixed with O-ring seals 6 on 11 respectively, 7 and adjust cover 16, the boss that has on the axle sleeve 4 and this circular groove match, by being fixed on relatively rotating of locating piece 3 restrictive axes 2 and axle sleeve 4 on the supporting base 1.The boss that has on the axle sleeve 4 is a running-fit with cooperating of the circular groove of barrel, and adjusting cover 16 is to prevent to damage by pressure when barrel is subjected to axial impact seal ring, the fricative possibility of elimination face.
During use, in the cylinder body cavity, fill earlier quasi-hydrodynamic lubrication fat, when carrying roller is in running order, spiral 9,12 all to send grease in the plain bearing 5 outside continuously than high thrust, and it is circulated in the bearing area, form the pressure oil film, force plain bearing 5 to separate with friction face, simultaneously at spiral 13,14, under 15 the effect, grease is flowed through between the boss of axle sleeve 4 and the circular groove and O-ring seals 6 is adjusted cover 16 through check valve, O-ring seals 7, after spiral 15 pressurizes again discharges outside the carrying roller, thereby dynamically the time, stoped sand, entering of water or other impurity, thus realize the spiral dynamic seal.Spiral 15 is formed first order sealing with seal ring 7, spiral 13,14 and seal ring 6 are formed second stage sealing, because spiral 9 is big than the thrust that spiral 12 produces, so after plain bearing 5 zones are full of grease, the part grease reaches seal ring 6 with the grease that enters from check valve, is discharged by spiral 15 at last, if this part grease pressure is bigger, this moment, closed check valve and independently satisfied the need oil mass of spiral 13,14,15 by it.When carrying roller is static, and stop entering of sand water, thereby realize static seal by seal ring 6 or 7.
Claims (3)
1, a kind of gold dust ship gap bridge carrying roller, form by supporting base, axle, axle sleeve, plain bearing, seal ring and barrel, it is characterized in that on the barrel of plain bearing both sides, having two spirals that rotation direction is opposite respectively, also has the circular groove that the boss that has with axle sleeve matches on the barrel, the circular groove side is equipped with seal ring, all have spiral on bottom land and the inner headed face from bottom land to the barrel outer end, this spiral and seal ring constitute spiral dynamic seal and seal ring static seal respectively.
2, gold dust ship gap bridge carrying roller according to claim 1 is characterized in that: the both sides of the circular groove of barrel also have the cover of adjustment 16.
3, gold dust ship gap bridge carrying roller according to claim 1 and 2 is characterized in that: in the filler port that barrel has check valve is installed.
