Problems solved by technology

The previous axial oil distributors all adopt the oil distribution seal sleeve structure. The disadvantage of this structure is that the oil distribution seal sleeve floats freely on the oil distribution shaft as a whole, and relies on the Babbitt alloy layer to support its entire weight.
When the size and weight of the oil distribution seal sleeve are large, large eccentricity and contact wear are likely to occur between the inner wall of the seal sleeve and the oil distribution shaft. Alloy burnout, which will affect the performance and service life of the oil distributor

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] as attached figure 1 As shown, a floating ring oil distributor includes a hollow oil distribution shaft 1, a double oil pipe 2 with double oil passages, a set of split tanks 3, and a set of adjustable distance rotary seal components 4. Two adjustable distance oil circuit joint bodies 5. One set of cooling oil circuit assembly 6. One set of static pressure rotary seal assembly 7. Two static pressure oil circuit joint bodies 8. Two rolling bearings 9. Two bearing retaining rings 10 , Two end caps 11, two rotating seals 12, anti-rotation support 13.

[0016] The double oil pipe 2 is inserted into the inner hole of the oil distribution shaft 1 . The split box body 3 is fixedly connected by the upper box body 3a and the lower box body 3b by screws, and is positioned on the oil distribution shaft 1 through the rolling bearing 9 . The rolling bearing...

Abstract

The invention relates to a floating ring oil distributor; a double oil duct is fitly connected in a bore of a distribution shaft, two ends of the distribution shaft are connected with spit boxes through rolling bearings, an adjustable pitch rotary sealing component and a static rotary sealing component are arranged in each split box, loosely sleeve the distribution shaft and are in clearance fit with the distribution shaft, each adjustable pitch rotation sealing component is connected with a hydraulic system hihg0pressure oil line through two adjustable distance oil circuit connectors to form a hydraulic loop, each static rotary sealing component is connected with a hydraulic system low-pressure oil line through a static oil circuit connector to form a hydraulic loop, a cooling oil circuit component is fixed to each split box, and a cooling oil duct outlet of each cooling oil circuit component is fixed above the corresponding rolling bearing. The size of an adjustable pitch propeller sealing clearance and the leakage of oil distribution seal can be controlled effectively at the premise of implementing hydraulic oil-distributing function, temperature rise of a seal pair is controlled, hydraulic oil-distributing efficiency is improved, and an adjustable pitch apparatus has improved operating performance and extended service life.

Description

technical field [0001] The invention relates to a ship power propulsion system, in particular to an oil distributor in a pitch control propeller device of the ship power propulsion system. Background technique [0002] At present, the oil distributor in the control pitch propeller device of the ship power propulsion system is generally divided into two types: the box type oil distributor placed at the free end of the gearbox and the shaft type oil distributor located on the intermediate shafting. The application of box-type oil distributor is more common, and there are many related researches. With the continuous development of ship technology, the shaft oil distributor has more and more applications due to its advantages such as being able to meet the rigid elastic installation of the gearbox and reducing the adverse effect of the long shaft system on the control accuracy of the controllable pitch propeller. The previous axial oil distributors all adopt the oil distributio...
