Abstract
The invention discloses a thin oil lubricating device capable of reducing oil leakage, which relates to the field of thin oil lubricating and sealing and comprises an operating equipment facility, a rotating shaft and a bearing, wherein the rotating shaft is rotatably arranged in the operating equipment facility through the bearing, a bearing baffle cover fixed at the end part of the operating equipment facility is sleeved on the rotating shaft, the operating equipment facility, an air inlet pipe and the bearing baffle cover are combined to form a sealed lubricating oil inner cavity, one end of the operating equipment facility is fixedly communicated with an air outlet pipe, the other end of the operating equipment facility is fixedly communicated with the air inlet pipe, the other end of the air inlet pipe is fixedly connected with an air outlet end of an air inlet control valve, and the air inlet end of the air inlet control valve is connected with. The invention has simple structure and low manufacturing cost, forms micro negative pressure in the sealed lubricating oil cavity through the exhaust fan and the air inlet regulating valve, prevents oil which is about to leak outwards from flowing out under the action of the negative pressure, and can reduce the temperature generated by operating equipment through air in the oil cavity.
Description
Technical Field
The invention relates to the field of thin oil lubrication sealing, in particular to a thin oil lubrication device capable of reducing oil leakage.
Background
In a production plant enterprise, operation equipment is indispensable, the operation equipment can not use lubricating oil, oil leakage phenomenon often occurs in operation, particularly, equipment lubricated by thin oil, such as operation equipment facilities, a speed reducer and the like, in the later period, oil seal aging abrasion is worn and abraded, the oil seal contact rotating part is worn and abraded, even if the oil seal is replaced, the oil leakage phenomenon can also occur, the equipment is easy to lack oil, and accidents occur.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a device for thin oil lubrication, which can reduce oil leakage.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a can reduce device for thin oil lubrication of oil leak, includes operation equipment facility, rotation axis, bearing, the rotation axis passes through the bearing and rotates to be installed in operation equipment facility, and the cover is equipped with the bearing that is fixed in operation equipment facility tip on the rotation axis and keeps off the lid, and operation equipment facility, air-supply line and bearing keep off the lid combination and form sealed lubricating oil inner chamber, the fixed and intercommunication of one end of operation equipment facility has a tuber pipe, and the fixed and intercommunication of the other end of operation equipment facility has the air-supply line, and the other end fixedly connected with air inlet control valve of air-supply line gives vent to anger the end, and air inlet control valve inlet end is connected with the air-supply line, and the other end fixed mounting of air-supply line has air cleaner, and the fixed and intercommunication of the other.
Preferably, the air outlet direction of the exhaust fan is consistent with the direction from the air outlet pipe to the air outlet pipe.
The invention has simple structure and low manufacturing cost, forms micro negative pressure in the sealed lubricating oil cavity through the exhaust fan and the air inlet regulating valve, prevents oil which is about to leak outwards from flowing out under the action of the negative pressure, and can reduce the temperature generated by operating equipment through air in the oil cavity.
