Description
Technical field
The utility model relates to marine mechanical equipment, particularly relates to the bearing assembly device of a kind of boats and ships in order to keep motion rotating shaft on boats and ships can keep accurate High Rotation Speed.
Background technique
Along with the pay attention to day by day that country is equipped extra large work field, and China is in order to realize the dream of ocean power, and shipping industry obtains great development.In recent years, national leadership also repeatedly indicates the significance and strategic importance of revitalizing China's shipbuilding industry in the speech of various occasion.
Bearing assembly is for providing support and revolute pair to rotating shaft.This just requires to have good quality of fit between bearing assembly and rotating shaft, enables bearing assembly can also allow rotating shaft very good rotation when supporting revolving shaft.Certainly, it also needs to have suitable gap simultaneously, in order to overcome the friction between rotating shaft and bearing.But due to boats and ships be navigate by water in waterborne, particularly some oceangoing ships travel on boundless sea.Marine changes of weather multiterminal, when particularly running into some extreme weathers, can allow boats and ships are abnormal to jolt at sea.This just has higher requirement to the quality of fit of the motion parts of boats and ships, the vibration between each motion rotating shaft and bearing assembly on boats and ships can be caused to be far longer than on non-ship domain with the vibration between rotating shaft and bearing because these jolt.And these vibrations can increase the friction and wear between rotating shaft and bearing assembly, the time has grown the working life that then can affect these movement parts.
The schematic diagram of existing boats and ships bearing assembly device is as shown in Figure 1: this bearing assembly forms primarily of the cover plate 06 of the bearing inner sleeve 02 be sleeved in rotating shaft 01, the bearing 03 be sleeved on bearing inner sleeve 02, the bearing outside 04 be sleeved on bearing 03, bearing support 05 and bearing support 05.Cover plate 06 is bolted on bearing support 05, and whole bearing 03, bearing outside 04 and bearing inner sleeve 02 are arranged in bearing support 05, and rotating shaft 01 is with bearing 03 high speed rotating.
There is following shortcoming in above-mentioned bearing assembly device:
As shown in Figure 1: (1), owing to there is axial clearance and radial clearance between bearing outside 04 and bearing support 05, in the process of rotating shaft 01 High Rotation Speed, it is larger that the existence in gap can allow rotating shaft 01 beat, can not high speed rotating accurately.If it is very little that this axial clearance and radial clearance are done by we, startup can be caused so again insensitive; Simultaneously because the friction between bearing and bearing support increases, heating is very fast, causes axis of rotation to have some setbacks.And along with the increase of time, the continuous aggravation of friction, also can allow this gap increasing.
(2) this bearing assembly is unfavorable for that the installation between rotating shaft and bearing assembly coordinates, and particularly rotating shaft longitudinal register is not accurate, precisely can not determine longitudinal mounting point of rotating shaft 01.
How to develop the bearing assembly that a kind of ship equipment uses, running up of rotating shaft can be realized, can friction be reduced again; The longitudinal mounting point of rotating shaft can be made accurate, easy for installation simultaneously; Then become the R & D design focus of apparel bearing class.
Model utility content
In order to solve the problems of the prior art, the purpose of this utility model be to provide a kind of surface friction drag little, start sensitive, power consumption is little, can support that rotating shaft is precisely rotated at a high speed, and the longitudinal mounting point of rotating shaft is accurate, and boats and ships bearing assembly device easy for installation.
For achieving the above object, the utility model is by the following technical solutions: a kind of boats and ships bearing assembly device comprises the bearing inner sleeve, bearing, bearing outside and the oil trap that are sleeved in rotating shaft that set gradually from inside to outside, the two end part of oil trap are respectively arranged with upper cover plate and lower cover plate, longitudinal damping device is provided with, bearing and be provided with radial damping device between upper cover plate and lower cover plate between described bearing outside and oil trap inwall; Described lower cover plate has radial taper circular hole, and the aperture of this taper circular hole reduces from outside to inside gradually, in this taper circular hole, straight pin, steel ball and spring are installed; Spring and steel ball are encapsulated in taper circular hole by straight pin; Under the action of the spring, steel ball can go out lower cover plate by partial denudation; Rotating shaft radially has a circle circular groove; After rotating shaft and bearing assembly install, steel ball can snap in the circular groove of rotating shaft under the action of the spring.
Adopt above structure, by the longitudinal damping device arranged between bearing outside and the inwall of oil trap, make when boats and ships jolt on the water surface time, even if rotating shaft is running up, also strong vibration can not occur between bearing outside and oil trap, can not there is circular runout in rotating shaft.Meanwhile, longitudinal damping device, can reducing friction resistance, makes rotating shaft also sensitiveer when initial start.When rotating shaft and bearing assembly are when installing, steel ball can snap in the circular groove of rotating shaft under the action of the spring, and the sound of card card can occur when snapping at steel ball in the circular groove in rotating shaft, and the feel of now installation personnel also can be different; Thus just can pick out longitudinal mounting point of rotating shaft easily, be conducive to the installation of rotating shaft.
Preferred version is, described longitudinal damping device is longitudinal damping shell fragment.Adopt longitudinal damping shell fragment, make the structure of this damping device simple, easy for installation.
Further preferred version, described radial damping device is also radial damping shell fragment.
Further preferred version, conveniently installs, and the inwall of described oil trap is provided with step.
The radial taper circular hole that described lower cover plate is offered is two.
In sum, boats and ships bearing assembly device of the present utility model, while ensure that rotating shaft can precisely be rotated at a high speed, also further reduces the frictional force between each moving element.Meanwhile, longitudinal mounting point accurate, makes motion more steadily reliable, the working life of bearing assembly device of the present utility model be substantially prolongs, reduce the operation and maintenance cost of enterprise, enhance the competitive ability of enterprise.
