The cooling unit of speed changer
Technical field
The present invention relates to speed changer, refer more particularly to the cooling unit of speed changer.
Background technique
Simple in structure, cheap chain type drawing machine is steel pipe's production enterprise the most conventional the most basic manufacturing mechanism in the steel pipe manufacturing.Along with the development of society and science and technology, improving product quality and production efficiency and reducing manufacture cost is numerous enterprises common concern and the problem that faces.Traditional drawing machine is equipped with the steel pipe's production demand that dull speed reducer can not satisfy nowadays develop rapidly, so, steel pipe's production producer passes through equipment transformation in various degree mostly, increase gear arrangement, make the chain type drawing machine can satisfy different product and different technologies requirement needs, improved simultaneously working efficiency.Yet, although the speed changer that increases newly speed freely can be changed to greatest extent,, because the mechanical part load that runs at full speed in the speed changer is large, the metal friction increases, Lubricating Oil Temperature constantly raise in the heat of generation made in the speed changer.And too high too early oxidized, the reduced viscosity of lubricant oil that makes easily of oil temperature causes oil film to be difficult for forming; Unsettled hydro carbons and colloid substance increase gradually simultaneously, cause carbon residue amount raising lubricant oil inefficacy in the lubricant oil, have seriously influenced thus the normal operation of speed changer.
Summary of the invention
Technical problem to be solved by this invention is: thus provide a kind of temperature that reduces lubricant oil to reduce the cooling unit of the speed changer of carbon residue amount in the lubricant oil.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the cooling unit of speed changer, comprise: housing, circulation fuel tank, cooling water tank and supplying tube and output tube, the upper and lower part of housing is provided with respectively delivery outlet and inlet opening, one end of output tube is connected with delivery outlet, the other end of output tube is connected with the top of circulation fuel tank, one end of supplying tube is connected with the inlet opening, the other end of supplying tube is connected with the bottom of circulation fuel tank, and described supplying tube and output tube pass from cooling water tank;
Described cooling box has two, described supplying tube and output tube pass from corresponding cooling water tank respectively, and water intake, the water outlet of two cooling water tanks are connected by connecting tube respectively, wherein, be provided with into head piece on the connecting tube, be provided with refluxing opening on another root connecting tube;
Described water intake and water outlet are separately positioned on the two ends of the upper and lower side of cooling box.
Further technical problem to be solved by this invention is: but the cooling unit of the speed changer of mechanical admixture in a kind of filtering lubricant oil, metal filings is provided.
In order to solve above-mentioned further technical problem, the technical solution used in the present invention is: described input pipeline is provided with filter screen at the end near the circulation fuel tank.
The invention has the beneficial effects as follows: the present invention is by supplying tube and output tube, so that the housing of speed changer becomes a connecting vessels with the recycle oil box-shaped, according to the principle of connecting vessels, lubricant oil is ceaselessly done to circulate and be need not to increase power source, energy free consumption; And, be provided with cooling water tank in the outside of supplying tube and output tube, so that lubricant oil is cooled, greatly reduce the temperature of lubricant oil when flowing through supplying tube and output tube, reduced the carbon residue amount in the lubricant oil; In addition, owing to be provided with filter screen at an end of the close circulation fuel tank of input pipeline, but the mechanical admixture in the filtering lubricant oil, metal filings has prolonged working life of speed changer.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, the cooling unit of speed changer of the present invention, comprise: housing 1, circulation fuel tank 2, cooling water tank 7 and 8 and supplying tube 3 and output tube 4, the upper and lower part of housing 1 is provided with respectively delivery outlet and inlet opening, one end of output tube 4 is connected with the delivery outlet on the top of housing 1, the other end of output tube 4 is positioned at the open-mouth of circulation fuel tank 2, one end of supplying tube 3 is connected with the inlet opening of the bottom of housing 1, the other end of supplying tube 3 is connected with the bottom of circulation fuel tank 2, and described supplying tube 3 and output tube 4 pass from cooling water tank 7 and 8 respectively; Described supplying tube 3 is provided with filter screen (belonging to conventional techniques, not shown in FIG.) at the end near circulation fuel tank 2; Cooling water tank 7 water intakes, water outlet lay respectively at the two ends of the upper and lower side of cooling water tank 7, cooling water tank 8 water intakes, water outlet lay respectively at the two ends of the upper and lower side of cooling water tank 8, cooling water tank 7 and 8 water intake, water outlet are connected by connecting tube 5 and 6 respectively, that is: cooling water tank 7 and 8 water intake are connected by connecting tube 5, cooling water tank 7 and 8 water outlet are connected by connecting tube 6, be provided with on the connecting tube 5 into head piece 51, be provided with refluxing opening 61 on the connecting tube 6.
During actual the use, enter head piece 51 and link to each other with water pipe, refluxing opening 61 links to each other with return pipe.According to the principle of connecting vessels, the housing 1 of speed changer keeps level with the pasta of circulation fuel tank 2.When the parts such as gear in the speed changer ran up, the high temperature grease that splashes entered output tube 4, through flowing into circulation fuel tank 2 after cooling water tank 7 coolings; Lubricant oil in the circulation fuel tank 2, because the principle of connecting vessels, by entering supplying tube 3 after the filter screen filtration, through flowing back in the speed changer after cooling water tank 8 coolings.Cooling water is entering cooling water tank 7 or at 8 o'clock, is subject to the shunting action of lubricant oil oil pipe, forms and refluxes, thereby the lubricant oil in supplying tube 3 and the output tube 4 has been played good cooling action.
