Description

A kind of plug-in type cooling structure of sliding bearing

Technical field

The utility model relates to the sliding bearing technical field, the concrete cooling structure that relates to a kind of sliding bearing, and this cooling structure can effectively reduce the operating temperature of sliding bearing.

Background technique

Sliding bearing mechanically is widely used various as basic component, present sliding bearing, and following several type of cooling is generally arranged: natural cooling, forced air cooling, water cooling, pressure lubrication oil cooling but wait.Air-cooled, water-cooled, pressure lubrication oil cooling but need to provide extrinsic motive, and after extrinsic motive broke down, bearing can not normally use, and complex structure, and fault is many, the operation expense height.Natural cooling efficient is not high, generally in order to improve heat dissipation potential, radiating fin is set structurally, makes the exterior appearance degree of sliding bearing be affected.

From three kinds of modes (radiation, convection current, conduction) of heat transmission, wherein transmission of heat is the fastest.Heat-pipe technology utilizes the Rapid Thermal hereditary property of heat-conduction principle and refrigerant, and the phase transformation by heat pipe self internal working medium is delivered to the heat of thermal objects outside the thermal source rapidly.Heat-pipe technology is widely used in industries such as aerospace, military project the earliest, after be introduced into the radiator manufacturing.Heat pipe has high thermal conductivity, and its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.Heat pipe has the density of heat flow rate variability, heat pipe can independently change the heating area of evaporator section or cooling section, promptly with less heating area input heat, and with bigger film-cooled heat quantity of heat given up, the heat transfer area input heat that perhaps heat pipe can be bigger, and with less film-cooled heat quantity of heat given up.Heat pipe also has thermostatic characteristics, and the each several part thermal resistance of general heat pipe does not become with the variation that adds heat basically, and therefore when the heating quantitative change, the temperature of heat pipe each several part also changes thereupon.

The model utility content

Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of plug-in type cooling structure of sliding bearing is provided.Being about to the direct-insert form of heat pipe is connected on the sliding bearing, the evaporator section of heat pipe inserts the hot-zone of sliding bearing, the condensating section of heat pipe stretches out outside the sliding bearing, and the liquid vapour conversion realization heat sinking function by heat-transfer working medium in heat pipe guarantees that the sliding bearing operating temperature is within the scope of permission.

In order to address the above problem the technical solution of the utility model is such:

A kind of plug-in type cooling structure of sliding bearing is characterized in that, comprises a tubular heat pipe, and described heat pipe connects sliding bearing in the mode of inserting; Heat pipe is divided into three sections of condensating sections, adiabatic section, evaporator section, and evaporator section inserts sliding bearing, and condensating section exposes in the sliding bearing outside.

Described heat pipe inserts link by one and connects sliding bearing.

Beneficial effect, the utility model reasonably are applied to sliding bearing with the plug-in type heat-pipe radiator, have improved the heat dissipation potential of sliding bearing self, can avoid or reduce by external impetus dispelling the heat, and reduce operating cost, economize on resources.Externally power system hinders in the time of can not normally moving for some reason, for sliding bearing provides suitable protection, has reduced the sliding bearing cooling system to powered attendant-controlled wheelchairs dependence.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is an inside heat pipe structural representation described in the utility model.

Fig. 2 is the structural representation that heat pipe described in the utility model inserts seat formula sliding bearing.

Fig. 3 is the structural representation that heat pipe described in the utility model inserts the end cover type sliding bearing.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1

Heat pipe is made up of the liquid refrigerant of shell, imbibition core and transferring heat energy, and inside heat pipe is pumped into negative pressure state, charges into suitable liquid, and this boiling point of liquid is low, easily volatilization.Tube wall is provided with the imbibition core, and the imbibition core is made of the capillary porous material, and tube core can be opened axial slot.Heat pipe is divided into three sections vertically, i.e. condensating section 11, adiabatic section 12 and evaporator section 13.For the protection heat pipe is not damaged, condensating section is outer can be provided with protective housing.

The material of heat pipe package can be: copper, aluminium, steel and various alloys etc.Pipe can be a standard circular, also can be special-shaped, as ellipse, square, rectangle, pancake, bellows etc.The evaporator section of heat pipe, condensating section can be helical bucklings such as straight line shape or circular, back-shaped, triangle, quadrilateral, polygonal, can be that light pipe also can be the band fin tube, can increase the area of contact of evaporator section and thermal source like this, increase the condensating section heat diffusion area, be convenient to heat and transmit fast.Condensating section is higher than evaporator section, and condensating section makes progress, or the spiral rising, or the straight line rising, or the curve rising, is convenient to be back to evaporator section behind the vapor condensation, realizes circulating.

With the evaporator section 13 of heat pipe, insert the hot-zone of sliding bearing as required.Heat pipe can insert the bearing hot-zone from the different azimuth of bearing, as the place ahead, rear, left side side, right side side, top, below etc.The hot-zone comprises oil sump, bearing shell matrix, bearing support, bearing support wall, bearing support gusset etc.Outside the condensating section 11 projecting shaft bearings.The heat of bearing hot-zone passes to working medium by evaporator section 13 tube walls, imbibition core, working medium vaporization, heat transferred steam at this moment.Steam flows to condensating section 11 and emits heat and condense into liquid under small pressure reduction, liquid flows back to evaporator section 13 along inner wall of tube shell again.So circulation reduces the operating temperature of sliding bearing.Thereby improved the operating conditions of bearing, reduced bearing cooling system powered attendant-controlled wheelchairs dependence.

The actual model of heat pipe and the quantity used is determined according to the calculated data of sliding bearing and the parameter of heat pipe.

Heat pipe described in the utility model can use separately, also can cooperate other types of cooling to use jointly.

Referring to Fig. 2, shown in the figure is seat formula sliding bearing, and wherein the evaporator section of heat pipe 1 passes in the oil sump 5 of bearing support 3 insertion bearings, and the pasta 4 of oil sump 5 floods the evaporator section of heat pipe 1, and heat pipe 1 also inserts link 2 coupling shaft bearings 3 by one.

Referring to Fig. 3, shown in the figure is the end cover type sliding bearing, and wherein the evaporator section of heat pipe 1 passes in the oil sump 5 of bearing support 3 insertion bearings, and the pasta 4 of oil sump 5 floods the evaporator section of heat pipe 1.Certain heat pipe described in the utility model can also be set in the sliding bearing of other kind in the mode of inserting, and plays the effect of cooling equally.
