Description
Technical Field
The utility model provides a grease collecting bottle with independently take out fat collection fat function especially relates to an automatic take out fat device for in the bearing lubrication, belongs to mechanical lubrication technical field.
Background
In the mechanical field, basically all large mechanical equipment cannot be separated from a bearing, and the bearing can not be lubricated in a rotating mode. Since there is a gap between the rotating shaft and the housing, there is no solid contact, and thermal expansion is allowed, grease in the bearing cavity needs to be sealed to prevent leakage of grease in the bearing cavity. The labyrinth seal is a device which is provided with a plurality of annular seal teeth arranged in sequence around a rotating shaft, a series of cut-off gaps and expansion cavities are formed between the teeth, and the purpose of leakage resistance is achieved by the throttling effect generated when the sealed medium passes through the gaps of the zigzag labyrinth. The labyrinth seal is suitable for high temperature, high pressure and high rotation speed, so that the seal form is widely used for sealing shaft ends and stages of steam turbines, gas turbines, compressors and blowers. However, the grease in the bearing cavity affects the lubrication performance and poses a safety hazard to the bearing due to deterioration and incorporation of abrasive dust during use, and the grease in the seal cavity needs to be renewed periodically or aperiodically.
The bearing seat which is generally small and convenient to update manually can be updated manually when a bearing is replaced or the bearing is shut down, and the large bearing seat mainly adopts a method of automatically supplementing lubricating grease or manually supplementing lubricating grease to extrude waste lubricating grease in a bearing cavity out of the bearing cavity and discharge the waste lubricating grease through a sealing piece or a grease discharge hole arranged on the bearing seat or a bearing end cover. The method for manually or automatically and forcibly supplementing the lubricating grease to extrude the waste lubricating grease has two problems: firstly, pressure is applied to a sealing element to cause sealing leakage, the environment is polluted and difficult to clean, and hidden dangers are left for the action safety of equipment maintenance personnel; secondly, the bearing cavity is heated due to the fact that lubricating grease is filled in the bearing cavity, so that the bearing is abraded in an accelerated manner, and the lubricating grease is deteriorated and loses efficacy in advance; in addition, the grease pumping mechanism adopting electric power as power also exists in the market at present, but the mechanism has the defects of complex installation, higher cost, poor use effect and the like, so the grease pumping mechanism has no popularization value. Most importantly, in some special working occasions, such as a pitch bearing of a wind generating set, grease in a bearing cavity is replaced once in a period, and the period is longer and is usually 12 months, so that when the grease pumping device is used, the grease pumping speed is required to be noticed, and the waste grease at the bottom in the bearing cavity can be pumped out in the period, and the grease retention required by normal work in the bearing cavity can be kept, so that extremely high requirements are provided for the design and the use of a grease pumping mechanism.
