Abstract
The utility model relates to an oil distributor with a sliding bearing, which comprises an oil distribution shaft, an oil distribution jacket, an oil distribution shell, a feedback loop, a feedback loop connecting rod and an oil distribution pipe, wherein the two ends of the oil distribution shell are supported through the sliding bearing, the outer side end part of the sliding bearing is provided with a mechanical sealing ring, and a rotary sealing ring is arranged on a combined surface of the sliding bearing and the oil distribution shaft. The utility model has the advantages that: since the oil distributor adopts the sliding bearing for supporting the oil distribution shell, the influence of the oil distribution shell on the oil distribution jacket is reduced, the wear speed on the relative rotating surface of the oil distribution jacket and the oil distribution shaft is reduced, and the service life of the oil distributor is prolonged; since the mechanical sealing ring and the rotary sealing ring are additionally arranged on the sliding bearing, the leakage of working oil is reduced; and since the feedback loop with a split structure is adopted, the installation and the maintenance are more convenient.
Description
Technical field
The utility model relates to a kind of adjustable pitch propeller oil distributor peculiar to vessel, and especially a kind of oilcan of joining has the oil distributor that plain bearing supports.
Background technology
Adjustable pitch propeller oil distributor peculiar to vessel is the vitals of realizing to roll adjustment hydraulic actuating cylinder fuel feeding, is to realize the indispensable parts of roll adjustment function.Oil distributor in the past, joining oilcan is to be installed on the oil distribution shaft by the support of joining oil jacket.Join oilcan and to join oil jacket relative static, join oil jacket and oil distribution shaft relatively rotates.The weight of joining oilcan is added in and joins oil jacket and oil distribution shaft relatively rotates on the face by joining oil jacket, has quickened to relatively rotate the wearing and tearing on the face, and tolerance clearance is strengthened, and causes the spillage of power fluid to increase.In addition, used feedback loop is generally integral structure, and installation and maintenance are all very inconvenient.
The utility model content
The purpose of this utility model is, at the easy wearing and tearing of traditional oil distributor plane of rotation friction pair, and the practical problems that the integral type feedback loop is installed and maintenance is all very inconvenient, provides a kind of oil distributor of new band plain bearing.
The purpose of this utility model is achieved in that a kind of oil distributor with plain bearing, comprise oil distribution shaft, join oil jacket, join oilcan, feedback loop, feedback loop connecting rod, oil distributing pipe, it is characterized in that: join the oilcan two ends and support by plain bearing, outboard end at plain bearing is provided with mechanical seal ring, is provided with rotating seal ring on the faying face of plain bearing and oil distribution shaft.
In the utility model: plain bearing is the annulus that inner headed face is provided with Babbitt matal, has the oil film wedge breach at babbitt layer.
In the utility model: described feedback loop is the annulus of separable type structure, and its cylindrical is provided with the feedback chute, the separable type structure to minute section by bolted connection after fixed packet be rolled on the oil distributing pipe.
The utility model has the advantages that: because oil distributor adopts plain bearing as support to joining oilcan, alleviated and joined oilcan, reduced to join oil jacket and oil distribution shaft and relatively rotated the rate of wear on the face, prolonged the service life of oil distributor joining the oil jacket influence; Owing on plain bearing, set up mechanical seal ring and rotating seal ring, reduced the leakage of power fluid; Owing to adopt the feedback loop of separable type structure, install and keep in repair convenient.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure: 1, inner oil tube, 2, outer oil pipe, 3, oil distribution shaft, 4, mechanical seal ring, 5, rotating seal ring, 6, plain bearing, 7, join oil jacket, 8, oil distribution shaft, 9, the separable type feedback loop, 10, the feedback loop connecting rod, 11, oil distributing pipe.
The specific embodiment
The nonrestrictive concrete structure that discloses the utility model embodiment of accompanying drawing, the utility model will be further described below in conjunction with accompanying drawing.
As seen from Figure 1, the utility model comprises oil distribution shaft 3, joins oil jacket 7, joins oilcan 8, feedback loop, feedback loop connecting rod 10, oil distributing pipe 11, joining oilcan 8 two ends supports by plain bearing 6, outboard end at plain bearing 6 is provided with mechanical seal ring 4, is provided with rotating seal ring 5 on the faying face of plain bearing 6 and oil distribution shaft 3.
During concrete enforcement, plain bearing is the annulus that inner headed face is provided with Babbitt matal, have the oil film wedge breach at babbitt layer, described feedback loop can adopt separable type feedback loop 9, special annulus by the separable type structure is formed, the same on the cylindrical with the integral type feedback loop, also be provided with the feedback chute, described separable type feedback loop 9 to minute section by bolted connection after fixed packet be rolled on the oil distributing pipe 11.
Because join oilcan 8, join oil jacket 7, the basic structure of oil distributing pipe 11 and position relation; And join inner oil tube 1 and the communication of the oil circuit between the outer oil pipe 2 annexation in oil jacket 7, oil distributing pipe 11 and the oil distribution shaft 3, the feedback information transfer mode of feedback loop and feedback loop connecting rod 10 is all consistent with traditional oil distributor, is not described in detail at this.
The oil distributor oil distributor with traditional in working order is the same: join oil jacket 7 and rotate with respect to oil distribution shaft 3.The operation pressure oil that positive car or reversing hydraulic fluid port are introduced enters inner oil tube 1 or outer oil pipe 2 by joining oil jacket 7, oil distribution shaft 3 and oil distributing pipe 11, by inner oil tube 1 and outer oil pipe 2 synergies the blade on the propeller hub is implemented roll adjustment.The straight-line motion of roll adjustment process can drive oil distributing pipe 11 and make synchronous straight-line motion, since separable type feedback loop 9 with captive joint with oil distributing pipe 11, the straight-line motion amount that separable type feedback loop 9 obtains converts electric signal transmission to operator's compartment then by feedback linkage 10 feedbacks.
Because plain bearing 6 peaces are changeed in the two ends of joining oilcan 8, support and join oilcan 8 on oil distribution shaft 3.The inner headed face of plain bearing 6 is provided with babbitt layer, has oil film wedge on babbitt layer.It is better lubricated that plain bearing can be obtained.Because pressure oil has leakage in the gap of joining between oil jacket 7 and the oil distribution shaft 3.The oil that rotating seal ring 5 in the plain bearing 6 can be guaranteed to enter in the babbitt layer oil film wedge is lubricated to plain bearing 6, stops them to external leakage; The mechanical seal ring 4 of plain bearing 6 outside end faces is the baffle ring of rotating seal ring 5, also is the backup seal of rotating seal ring 5, can continue to stop oil to external leakage.
