Abstract

The utility model discloses a cooling structure for a rolling bearing. The cooling structure is characterized by comprising cold air production equipment (1), an air inlet pipe (2), a bearing, a bearing pedestal inner cavity (3) and an air outlet pipe (4), wherein the air inlet pipe (2) is used for communicating an air inlet of the cold air production equipment (1) with the bearing pedestal inner cavity (3); the bearing pedestal inner cavity (3) is communicated with the atmosphere by the air outlet pipe (4). According to the cooling structure for the rolling bearing, the cold air production equipment is used for directly cooling the rolling bearing; foreign matters are prevented from being carried into the bearing pedestal inner cavity and the bearing is prevented from being damaged; the service life of the bearing is prolonged and a cooling effect of the rolling bearing is greatly improved.

Description

A kind of cooling structure of rolling bearing

Technical field

The utility model relates to a kind of cooling structure of rolling bearing.

Background technique

The existing type of cooling to rolling bearing mainly contains two kinds, a kind of is oil cooling, another kind is air-cooled, the latter is mainly the heat by air band bearing running mobile around bearing support, cooling to carry out, it has utilized the convection coefficient of motion air than high this feature of the convection coefficient of still air, but, in practice, moving air, because usually carrying many fouls or impurity secretly, should not be directly inputted to the inside of bearing support, otherwise very easily causes rolling bearing to damage, shorten working life, and this cooling effect is also bad.

Model utility content

For above-mentioned deficiency, the utility model provides a kind of cooling effect better, and can prevent that foreign matter from entering the rolling bearing cooling structure of bearing support inner chamber.

The utility model is to realize by such technological scheme: a kind of rolling bearing cooling structure, comprise cold wind making equipment, air intake pipe, bearing and bearing support inner chamber and air outlet tube, wherein, air intake pipe is communicated with the exhaust outlet of cold wind making equipment with bearing support inner chamber, air outlet tube is communicated with bearing support inner chamber with atmosphere.

Further, described cold wind making equipment is cold air jet machine.

Further, described cold air jet machine comprises drying system, refrigeration system and control system.

Owing to having adopted said structure, the beneficial effects of the utility model are as follows: adopt cold wind making equipment rolling bearing to be carried out directly cooling, avoided foreign matter to be brought into bearing support inner chamber, prevent that bearing is damaged, improve the working life of bearing, and greatly improved the cooling effect of rolling bearing.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of this case cooling structure.

Embodiment

In order to be more expressly understood the purpose of this utility model, technological scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection domain of the present utility model is not limited in following examples.

As shown in Figure 1, a rolling bearing cooling structure, comprises cold wind making equipment 1, air intake pipe 2, bearing and bearing support inner chamber 3 and air outlet tube 4, wherein, air intake pipe 2 is communicated with the exhaust outlet of cold wind making equipment 1 with bearing support inner chamber 3, air outlet tube 4 is communicated with bearing support inner chamber 3 with atmosphere; Described cold wind making equipment 1 adopts cold air jet machine; Described cold air jet machine comprises drying system, refrigeration system and control system.

During work, the pressurized air of normal temperature is sent in cold wind making equipment 1, be sent in cold air jet machine, and enter refrigeration system after the absorption of drying system, thereby generate full-drying type cold wind, the temperature of this cold wind can reach subzero 40 to 60 degree, the air-flow that these cold wind form directly enters into bearing support inner chamber 3 through air intake pipe 2, to carry out cooling to rolling bearing, after heat in cold airflow absorption axes bearing inner chamber 3, by air outlet tube 4, discharged, thereby greatly reduce the temperature of rolling bearing, effectively avoid foreign matter to enter into bearing support inner chamber 3, mentioned the cooling effect of rolling bearing, simple in structure, use reliable.
