The utility model discloses can provide the static pressure and provide force -feed lubrication for the shafting when the lubrication of low -speed state dynamic pressure not establish, solve the lubricated low -speed that the exists problem that rubs of current dynamic pressure.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to the marine water lubricating bearings of a kind of band pressurize device in short-term.
Background technology
Water-lubricated slide bearing is as the new technology occurred in recent years, and compared with traditional lubricating oil, the specific heat of water is big, and the cooling performance for friction heating is better than oil, and water lubricating is pollution-free simultaneously, is not endangered by environment. Therefore water-lubricated slide bearing is able to fast development and application in field, naval vessel. Current marine water lubricating bearings is based on dynamic pressure bearing, and when oar axle runs, bearing soaks in seawater, is lubricated by the water film formed between axle journal and bearing materials. When ship propeller axle and tail bearing friction pair are under the operating modes such as low speed, heavy duty, startup, shutdown; between axle and bearing, lubricating water film may be destroyed; hydrodynamic force film can not be fully formed; part bearing zone is in boundary lubrication condition and extremely unstable; cause and sticky-slip model occurs between axle journal and bearing; produce abnormal vibrations and noise, accelerate bearing wear simultaneously.
At present the solution means of the problems referred to above are mainly contained two kinds of technological approaches: water lubricating bearing material, bearing structure, axle and the alignment case between bearing surface situation, axle and bearing, water temperature, water quality characteristic etc. reduce scope and the probability that abnormal friction occurs to the first by optimizing; Its two be introduce static pressure module, composition dynamic and static pressure composite bearing, combine static pressure bearing and the feature of dynamic pressure bearing, during low speed, utilize static pressure module to realize mechanical lubrication, utilize during high speed dynamic pressure performance realize lubrication.
In actual use, the propeller bearing of boats and ships is mainly in startup and stopping process, low speed friction phenomenon can be produced, normal operation rotating speed generally all can away from low speed friction district, therefore a kind of method that can give full play to by water lubricating it is badly in need of in startup and stop phase, but low speed friction generation rotating speed can only suitably be reduced by the first method to a certain extent above-mentioned, can not fundamentally solve the problem of low speed lubrication. Although the 2nd kind of method can fundamentally solve the problem of low speed lubrication, but need to consume a large amount of energy, and voltage supply module is in intermittence, non-steady voltage supply state, boats and ships acoustical behavior and comfortable property, by producing bigger vibration and noise, are brought disadvantageous effect by self.
In sum, still lack a kind of startup at screwshaft at present and can effectively solve low speed friction problem with stop phase, do not consume again the marine water lubricating bearings of additional energy source simultaneously, bring disadvantageous effect to ship vibration noise abatement and the security of axle system, need breakthrough badly.
Summary of the invention
The utility model is for the problems referred to above, the marine water lubricating bearings of a kind of band pressurize device in short-term is proposed, it is replace traditional pressure shared module with energy storage, when lower-speed state water-lubricated dynamic is lower, for bearing provides static pressure, and at high speeds, from water film, energy is absorbed when dynamic pressure is higher, when this external axle is subject to shock load, energy storage is also by absorbing transient impact, it is achieved buffering effect.
Realize the technical solution of the utility model as follows:
A marine water lubricating bearings for band pressurize device in short-term, primarily of dynamic pressure water lubricated bearing, energy storage and multiple current regulator composition; Having multiple water chamber on the bearing shell of described dynamic pressure water lubricated bearing, each Shui Qiang center is provided with prosopyle, and each prosopyle connects energy storage by the current regulator corresponding with it.
Further, on the bearing shell of the utility model dynamic pressure water lubricated bearing, circumferentially etc. spacing offers N number of water chamber, and described N is even number, and is more than or equal to 4.
Before axle system operates, should be that energy storage is sufficient in advance enough supports the pressure that axle system is in good lubrication state. In axle system start and stop process, pressure is delivered in water chamber via prosopyle by energy storage, it is achieved mechanical lubrication effect, solves the low speed friction problem that dynamic pressure water lubricated bearing exists.
Under axle system normal operation, dynamic pressure water film pressure is very high, then this pressure can be energy storage accumulation of energy via prosopyle, and energy storage also can effectively absorb the energy that axle system transient impact produces simultaneously, reduces vibration to the transmission provided, reaches the effect of buffering absorbing.
Useful effect
The utility model compares to existing technology and has following technical superiority: one, can when lower-speed state hydrodynamic lubrication is not set up, it is provided that static pressure provides mechanical lubrication for axle system, solves the low speed friction problem that existing hydrodynamic lubrication exists. Two, do not need additional energy source, abnormal vibrations and noise also can not occur, be specially adapted to the naval vessel bearing that noise and energy requirements is high. Three, system is simple, and maintenance, repair are convenient.

Embodiment
Novel it is described in detail below in conjunction with accompanying drawing is practical further.
As shown in Figure 2, the marine water lubricating bearings of a kind of band of the utility model pressurize device in short-term, primarily of dynamic pressure water lubricated bearing, energy storage and 4 current regulators compositions; On the bearing shell of described dynamic pressure water lubricated bearing, circumferentially etc. spacing offers 4 water chambeies, and the bearing shell inwall not offering water cavity segment forms Sealing Surface, as shown in Figure 1. Prosopyle is offered at each Shui Qiang center, and each prosopyle is connected with energy storage by current regulator corresponding to it. Energy storage is filled with in advance and is enough to support the pressure that axle system is in good lubrication state. When axle system starts, power water lubricating film is not yet set up, the pressure that energy storage pressure is greater than in water film, then energy storage-current regulator-bearing water chamber just constitutes static pressure bearing three elements, water in energy storage water chamber is namely by hydrostatic pressure, there is provided mechanical lubrication to axle system, allow axle also keep well lubrication under lower-speed state; When axle system is in normal operation time, dynamic pressure film is formed, dynamic pressure water film pressure is greater than energy storage pressure, then this pressure can be energy storage accumulation of energy, energy storage also can effectively absorb the energy that axle system transient impact produces simultaneously, reduce vibration to the transmission provided, reach the effect of buffering absorbing; When, in axle system stopping process, energy storage-current regulator-bearing water chamber plays again Static compression performance, for axle system provides good lubrication. In a word, with the use of the water lubricated bearing that practicality is novel proposed, it is possible to the effectively bearing lubrication problem under the startup of solution ship propeller axle, running and all operating modes of stopping, additionally not consuming any energy simultaneously, do not produce additional vibratory and noise, have a extensive future.
In sum, these are only the better embodiment of the present invention, it is not intended to limit protection scope of the present invention. Within the spirit and principles in the present invention all, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
