Abstract
The invention discloses a sliding watertight rudder bearing which comprises a rudder bearing body (1) and a bush (6). The bush (6) is embedded in the rudder bearing body (1), and the bush (6) and the rudder bearing body (1) are in clearance fit. An oil distributing ring (4) is arranged on the upper portion of the bush (6), sealing gaskets (3) are arranged at the upper end and the lower end of the oil distributing ring (4) respectively, a screwed-in screwed joint (5) is arranged on the rudder bearing body (1), and the screwed-in screwed joint (5) is communicated with the oil distributing ring (4). A gland (2) is arranged on the top of the rudder bearing body (1), the gland (2) is fixed on the rudder bearing body (1) through bolts, and the gland (2) tightly presses the sealing gaskets (3), the oil distributing ring (4) and the bush (6) into the rudder bearing body (1). According to the sliding watertight rudder bearing, the rubber bearing and a rudder stock are made to be in sliding fit by using a watertight structure, lubricating grease cannot seep out in the using process, sea water also cannot seep in, and therefore good lubricity and good corrosion resistance are ensured.
Description
Technical field
The present invention relates to a kind of slip watertight rudder bearer.
Background technology
Rudder is a kind of very important and indispensable special-purpose outfitting of boats and ships, rudder for ship mainly is comprised of rudder blade and rudder stock, rudder blade is the part that produces hydraulic pressure, the effect of rudder stock is rotate rudder blade and guarantee that rudder blade has enough intensity, the action principle of rudder is when current, with certain angle of attack, to rush on rudder blade the time, has just produced dynaflow, and this application force is by rudder stock transmission hull, thereby force ship turning, also just reached the purpose of adjusting course.
Rudder for ship can reliablely and stablely the work normal operation that be unable to do without steering wheel and the reliable supporting of rudder bearer, boats and ships rudder bearer under sail easily produce wearing and tearing along with frequent rotation of rudder stock, the while rudder bearer submerges in seawater for a long time, be subject on the one hand the corrosion of seawater, solid impurities in seawater enters in rudder bearer the jam that strengthens the wearing and tearing of rudder bearer and easily cause rudder bearer simultaneously, once rudder bearer serious wear or jam, navigating mate just can't correctly be controlled course, ship without the active course not only can not guarantee the safety of navigation, and can not arrive port of destination.
Summary of the invention
In order to address the above problem, the invention provides a kind of slip watertight rudder bearer, adopt watertight structure to make bearing fit between rudder bearer and rudder stock, in use procedure, grease can't ooze out, and seawater also can't infiltrate, and has guaranteed lubricity and corrosion stability preferably.
The present invention has adopted following technical scheme: a kind of slip watertight rudder bearer, comprise rudder bearer body and lining, and the matrix platform that the rudder bearer body interior is reducing, lining is T-shaped structure, lining embeds in the rudder bearer body, is free-running fit between the two; The top of described lining is equipped with oil distributing ring, at the two ends up and down of oil distributing ring, is respectively equipped with packing seal, on the rudder bearer body, with corresponding position, oil distributing ring position, is provided with the screw-in threaded connection, and described threaded connection is communicated with oil distributing ring; The top of described rudder bearer body is provided with gland, and gland is bolted on the rudder bearer body, and described gland is by packing seal, and oil distributing ring and lining are pressed in the rudder bearer body.
The below of described lining is provided with seal ring, and the below of rudder bearer body is provided with trim ring, and described trim ring is pressed abd fixed on sleeve by seal ring, and trim ring is bolted on the rudder bearer body; The lower end of described oil distributing ring is provided with two-layer packing seal; Described packing seal is the exoskeletal rubber seal of J type.
The present invention has following beneficial effect: packing seal of the present invention is the exoskeletal rubber seal of J type, its interior tapered face mounting spring, under the spring tension effect, make packing seal and rudder stock hug and do not produce the grease Seepage, do not affect the smooth rotation of rudder stock simultaneously, fill it up with lubricating oil/fat by screwing in threaded connection between packing seal, in order to avoid between seal ring and rudder stock, dry friction occurs, seal ring and packing seal can effectively stop water to infiltrate wherein, avoid solid impurities in water to rotate and impact rudder stock.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention is a kind of slip watertight rudder bearer, comprise rudder bearer body 1 and lining 6, rudder stock run through rudder bearer body 1 and with rudder bearer body 1 free-running fit, rudder bearer body 1 inside is the matrix platform of reducing, lining 6 is T-shaped structure, lining 6 embeds in rudder bearer body 1, be free-running fit between the two, the below of described lining 6 is provided with seal ring 8, the below of rudder bearer body 1 is provided with trim ring 7, and described trim ring 7 is pressed abd fixed on lining 6 bottoms by seal ring 8, and trim ring 7 is bolted on rudder bearer body 1; The top of described lining 6 is equipped with oil distributing ring 4, at the two ends up and down of oil distributing ring 4, is respectively equipped with packing seal 3, and the lower end of described oil distributing ring 4 is provided with two-layer packing seal 3, and packing seal 3 is the exoskeletal rubber seal of J type; Be provided with and screw in threaded connection 5 with oil distributing ring 4 corresponding positions, position on rudder bearer body 1, described threaded connection 5 is communicated with oil distributing ring 4; The top of described rudder bearer body 1 is provided with gland 2, and gland 2 is bolted on rudder bearer body 1, and gland 2 is by packing seal 3, and oil distributing ring 4 and lining 6 are pressed in rudder bearer body 1, packing seal 3, oil distributing ring 4 and lining 6 all with the rudder stock free-running fit.
