Automatic lubrication and waste grease collection system for bearing

Abstract

The invention relates to an automatic lubrication and waste grease collection system for a bearing. The automatic lubrication and waste grease collection system comprises a lubricant pump, an electromagnetic valve I, an electromagnetic valve II, a waste grease collecting device and an electronic control device. The waste grease collecting device comprises grease suction units, a waste grease collecting pressure grease-way, a waste grease collecting grease-way and a waste grease collecting container. The grease suction units can suck and discharge waste grease inside the bearing through pressure of the waste grease collecting pressure grease-way and spring restoration. The electronic control device is used for controlling the electromagnetic valve I and the electromagnetic valve II to be on and off. According to the automatic lubrication and waste grease collection system, due to the design of the waste grease collecting pressure grease-way, good automatic lubrication of the bearing can be guaranteed; and meanwhile, waste grease discharged from the bearing can be automatically collected in time as required, and therefore the system is convenient to use and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of lubrication, in particular to a bearing automatic lubrication and waste grease collection system. technical background [0002] In the wind power generation and construction machinery industries, large bearings or slewing supports are widely used. In order to improve the service life of the bearings, regular quantitative lubrication of the bearings is required. At present, manual grease injection is mainly used, but it is difficult to achieve precise quantitative lubrication. Too much will cause waste and environmental pollution, and too little will not meet the purpose of lubrication, causing serious wear and tear on the equipment and affecting the service life of the equipment.

Problems solved by technology

[0002] In the wind power generation and construction machinery industries, large bearings or slewing supports are widely used. In order to improve the service life of the bearings, regular quantitative lubrication of the bearings is required. At present, manual grease injection is mainly used, but it is difficult to achieve precise quantitative lubrication. Too much will cause waste and environmental pollution, too little can not meet the purpose of lubrication, make the equipment wear seriously, and affect the service life of the equipment

[0003] In terms of waste grease collection, at present, oil collection bottles are usually installed directly in each grease discharge hole to collect waste grease. It is easy to cause leakage, but large-scale bearings or slewing supports often have relatively large diameters, and the number of grease discharge holes is very large, and it is difficult to take out the oil collection bottle in some positions for replacement; It is difficult to collect the waste fat by the passive collection method of the bottle
