Abstract
The utility model discloses a bearing housing with a dustproof protector, which consists of a housing, a cover and a sealing gasket. A vent pipe with a movable joint is connected to the cover and is connected with a pressure air supply pipeline through a switch. The bearing housing with the dustproof protector is connected with the pressure air supply pipeline, pressure in the bearing housing is higher than that outside the bearing housing, air leaks outwards, external dust cannot enter the bearing housing, environment polluted by the external dust is eliminated in the bearing housing, and accordingly the service life of a bearing is prolonged. In addition, the pipelines, the switch and the like of the bearing housing are materials low in cost, and continuous production of the bearing housing is guaranteed, while the bearing high in price is prevented from being damaged.
Description
Technical field
The utility model relates to a kind of bearing box.
Background technique
The bearing of long-term operation under the bigger working environment of dust because the bearing box imprecision is often invaded by dust, causes bearing to quicken to damage, and change bearing and need shut down, and not only the bearing price is often very high, also causes the whole production link to pause and delays production.The bearing of the lift of chemical enterprise for example, lowest price is also wanted 1.8 ten thousand yuan, causes serious economy loss to enterprise.
Summary of the invention
The purpose of the utility model provides a kind of bearing box with anti-dust protecting device, and because of the gas of band pressure is arranged in its box, extraneous dust is difficult to get into, and has reduced disorderly closedown and economic loss.Its technological scheme is following: the bearing box of band anti-dust protecting device, form by box body, lid and sealing gasket.On lid, be connected to the breathing pipe of band union, breathing pipe is pressed gas supply line through the switch connecting band.
The bearing box connecting band of band anti-dust protecting device is pressed gas supply line, makes the box internal pressure greater than outside the box, and gas is to external leakage, and extraneous dust can not get in the box, has guaranteed that the box inner bearing does not have the environment of outside contamination, has prolonged bearing working life.With material at a low price such as pipeline, switch, guaranteed that continuous production and high price bearing are without prejudice.
Description of drawings
Fig. 1 is the structural representation of the bearing box of band anti-dust protecting device.
Embodiment
Be further described below in conjunction with accompanying drawing.The bearing box of the band anti-dust protecting device shown in the accompanying drawing 1 is made up of box body 1, lid 2 and sealing gasket.On lid, be connected to the breathing pipe 4 of band union 3, breathing pipe is pressed gas supply line 6 through switch 5 connecting bands.After connecting switch, the bearing box internal pressure is higher than the outside, and dust advances less than in the box, has guaranteed the proper functioning of bearing.
Claims (1)
1. the bearing box of band anti-dust protecting device is made up of box body, lid and sealing gasket, it is characterized in that: on lid (2), be connected to the breathing pipe (4) of band union (3), breathing pipe is pressed gas supply line (6) through switch (5) connecting band.
