Abstract
The invention relates to a cooling device of a middle bearing of a ship. The device comprises a middle shaft, the middle bearing for supporting the middle shaft, and a fan, wherein a gear ring is fixedly mounted on the middle shaft; a gear is fixedly mounted on a driving shaft of the fan; the gear ring is engaged with the gear. The device has the characteristics of being simple in structure, low in failure rate and easy to implement.
Description
Technical field:
The present invention relates to boats and ships intermediate bearing.
Background technique:
Boats and ships intermediate bearing time can produce higher temperature in work, easily causes oil body to decline, can not form oil film and cause lubrication failure, causes having an accident.Conventional solution is to be placed in lubricant oil with water-cooling tube, by the cooling water reduction oil temperature of circulation.But the component such as water pump, water pipe, valve break down at work, cause intermediate bearing to damage and the thing that affects ship's navigation happens occasionally, had a strong impact on the economical operation of boats and ships.Not yet find at present good solution.
Summary of the invention:
For prior art above shortcomings, the object of the invention is to provide a kind of boats and ships intermediate bearing air cooling equipment, it has simple in structure, failure rate is low, the feature easily realizing.
In order to solve the problems of the technologies described above, the scheme of technical solution problem of the present invention is: a kind of boats and ships intermediate bearing air cooling equipment, comprise jack shaft, support on the intermediate bearing, fan, described jack shaft of this jack shaft and be installed with gear ring, on the live axle of described fan, be installed with gear, described gear ring and described gear are intermeshing.
Adopt after such scheme, owing to being installed with gear ring on jack shaft, on the live axle of fan, be installed with gear, gear ring and gear are intermeshing, jack shaft drives fan work by gear transmission while rotating, the wind of fan outlet, to the housing of intermediate bearing, reaches by reducing the temperature of housing the object that reduces bearing bush temperature, guarantees intermediate bearing normal operation.On the other hand, because the rotating speed of jack shaft is not high, the power of fan is little, utilizes jack shaft drive fan can not cause damage to jack shaft.Also due to directly by gear transmission drive fan, and gear ring and gear have good mechanical property and wear-resisting property, thus whole device simple in structure, rate of fault is lower, easily realize.
Boats and ships intermediate bearing air cooling equipment of the present invention can also reduce oil temperature device co-operation with cooling water.
One side of intermediate bearing is provided with gear ring and by the fan of this driving.
The both sides of intermediate bearing are all provided with gear ring and by the fan of this driving.
Gear ring is Hafu-type structure, by two semicircle gear rings, is constituted.
The outer surface of the housing of intermediate bearing is provided with radiating groove, to increase heat diffusion area.
Bush temperature detecting degree display unit, oil temperature display unit and cooling water flow quantity display apparatus are installed on intermediate bearing.
Protective housing is installed on fan, prevents fan blade injury people and thing around.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, boats and ships intermediate bearing air cooling equipment of the present invention is described in further detail.
Fig. 1 is the structural principle schematic diagram of boats and ships intermediate bearing air cooling equipment of the present invention.
Embodiment:
In Fig. 1, intermediate bearing 2 supports on jack shafts 1, jack shaft 1 and is installed with gear ring 5, gear ring 5 is Hafu-type structure, the fan blade of fan 3 points to intermediate bearing 2, on the live axle of fan 3, be installed with gear 4, gear 4 is intermeshing with gear ring 5, the diameter of gear 4 is far smaller than the diameter of gear ring 5, so even the rotating speed of jack shaft 1 is lower, fan 3 still can High Rotation Speed, the wind of fan 3 outlets is to the housing of intermediate bearing 2, by reducing the temperature of surface of shell, reduce the temperature of bearing shell, thereby intermediate bearing 2 can be worked.
