Description

Oil collection bottle with self-liposuction and grease collection functions

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.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides an overall structure for anti beat type multi-lip sealing device in axis of rotation is shown as figure 1, and figure 1 is the state structure picture when the accumulator rotates to the top along with the bearing, and bottle 3 is in the state of invering this moment. The oil collecting bottle is arranged on the grease discharging channel 2 of the bearing seat 1 and synchronously rotates along with the bearing seat, the oil collecting bottle at least comprises a connector and a bottle body 3, the connector is in a step shape and consists of a large head 4 and a small head 5 which are of hollow structures, and the structure of the connector is shown in figure 2. Wherein the small head 5 is fixed in the grease discharging channel, the upper part of the small head is hollow, the lower part of the small head is provided with threads and is fixed in the grease discharging channel through the threads, the big head penetrates through the bottle cap 6 and is positioned in the bottle body, the bottle cap is fixed on the bearing seat through extrusion, and the bottle body is fixed with the bottle cap through threaded connection. A sealing gasket 11 is arranged between the big head and the bottle cap and used for sealing a gap between the big head and the bottle cap so as to prevent grease entering the bottle body from leaking from the bottle opening.

Be provided with the slider in the bottle, the slider comprises connecting rod 7 on upper portion and balancing weight 8 of lower part, and wherein the connecting rod is located the inside passage of connector and can follow inside passage reciprocating slide under the action of gravity of balancing weight, and the top of connecting rod is provided with scrapes alicyclic 9, scrapes the connecting rod diameter of fat ring below and reduces, and the inside passage of adapter between form and store up fat chamber 10, scrape the fat that the alicyclic will store up the fat intracavity when the connecting rod slides outwards and scrape to the bottle in. Two guide rods 13 are installed at the bottom of the big head, a limiting block 14 is arranged at the bottom of each guide rod, two guide holes are formed in the balancing weight corresponding to the guide rods, the guide rods penetrate through the guide holes, and the balancing weight slides along the guide rods. The part of the upper part of the limiting block contacting with the balancing weight and the part of the lower part of the big head contacting with the balancing weight are both provided with a damping element 15. In this embodiment, the damping element is a spring, which is used to reduce the loss caused by the impact of the weight.

An exhaust pipe 12 communicated with the outside is arranged in the bottle body, and the exhaust pipe is used for exhausting gas in the bottle body when grease enters the bottle body. The bottle is characterized in that a guide cylinder 16 is further arranged in the bottle body, the guide cylinder is fixed in the bottle body, the top of the guide cylinder is hermetically connected with the bottle opening of the bottle body, the bottom of the guide cylinder is suspended, and the large head, the sliding block and the guide rod are all located inside the guide cylinder. Under the flow guide effect of the flow guide cylinder, grease in the bottle body flows outside the flow guide cylinder, and in order to prevent the grease entering the bottle body from flowing back to the bearing cavity when the bottle body is inverted.

The utility model provides a working principle of collection oil bottle as follows: when the oil collecting bottle rotates to the bottommost part along with the bearing during operation, the grease in the bearing cavity is located above the grease discharging channel at the moment, the waste grease in the grease is deposited on the bottom layer due to high density, so that the viscous waste grease is gathered in the grease discharging channel and the inner channel of the connector, and the sliding block and the grease scraping ring slide to the bottom of the bottle body at the moment. With the bearing rotating continuously, when the oil collecting bottle rotates to the topmost part along with the bearing (as shown in fig. 1), the sliding block and the grease scraping ring slide to the topmost part of the bottle body, the grease scraping ring ejects out the waste grease in the internal channel, however, because the upper part of the small head is hollow, a small part of grease still passes through the hollow part and enters the grease storage cavity below the grease scraping ring. The bearing continues to rotate, and in the process that the oil collecting bottle rotates to the bottommost part along with the bearing, the sliding block and the grease scraping ring slide downwards, so that a small part of grease in the grease storage cavity is scraped and conveyed into the bottle body. Through tests, the single grease scraping amount is only in milligram level, so that the grease retaining amount required for normal work in the bearing cavity can be maintained.
