Abstract

The utility model discloses a bearing oiling device which comprises a bearing end cover. An oil filler hole is formed in the bearing end cover, a soft plug body is arranged at the position of an inlet of the oil filler hole, and an oil absorption body is arranged in the oil filler hole and abuts against the position of the gap formed between a bearing seal ring and a bearing outer ring. The bearing oiling device is simple in structure, easy to manufacture and convenient to maintain. Due to the fact that lubrication media are filled through an injector, filling quantity is accurate, lubrication media cannot leak out of the oil filler inlet, and cleaness of the lubrication media can be guaranteed. The soft plug body can automatically seal the oil filler inlet after the injector is pulled out, and dust and sundries can be prevented from entering the oil filler inlet. The oil absorption body can fully absorb filled lubrication oil, and the lubrication oil is prevented from leaking out from the side surface of a bearing and polluting internal environment of equipment, the lubrication media can be provided for the bearing at any time, the oil absorption body is equivalent to a small-size oil depot, and a lubrication effect is good. A counter bore at inlet end of the oil filler hole is beneficial to inserting and positioning of the soft plug body which can be prevented from dropping into a deep position of the oil filler hole. A hollow bolt can prevent the soft plug body from coming off the oil filler hole.

Description

A kind of bearing oiling device

Technical field

The utility model relates to a kind of bearing oiling device.

Background technique

Bearing is a kind of very important component in contemporary machinery, and its major function is the supported mechanical solid of rotation, and reduces the mechanical load friction factor of equipment in transmission process, can be divided into rolling bearing and sliding bearing by the friction mode.The life-span of bearing becomes the key factor in restriction machinery life-span, for improving bearing life, must give its good lubricating.At present the lubricating system of bearing has two kinds of grease lubrication and oil lubrications.Lubricating grease is because mobility is little, can remain in bearing inside, and after a certain amount of lubricating grease of filling, bearing can well operation within a period of time, but lubricating grease viscosity is large, makes the bearing running resistance large, is unsuitable for the High Rotation Speed operating mode.And lubricant oil is due to good fluidity, easily reveals from pouring orifice and bearing portion during oiling, pollutes for machinery inside, sometimes also needs to design complicated oil supply system.

Further, notice of authorization number discloses a kind of bearing oiling device for megawatt level wind generating set in the patent of CN 201688113U, its technological scheme that adopts is: a kind of bearing oiling device for megawatt level wind generating set, it is characterized in that: described device includes bearing seat, oiling joint and oil filler pipe, described bearing seat center has oil guide slot, described oiling joint is drawn together as in this oil guide slot, described oiling joint center has an oil hole, and described oil filler pipe is spun on the oiling joint.But in this patent, there is the drawback that oil filling process lubricant oil is easily revealed equally in disclosed oiling device, and simultaneously, the bad grasp of oil filling amount in this patent exists to add few problem of adding.

The model utility content

For the problems referred to above that prior art exists, it is a kind of simple in structure that the utility model provides, and in filling process, lubricant oil is difficult for overflowing pollution workpiece on every side, the more accurate bearing oiling device of oil filling amount.

To achieve these goals, the utility model adopts following technological scheme: a kind of bearing oiling device, comprise bearing (ball) cover, described bearing (ball) cover is provided with oil hole, the ingress of described oil hole is provided with soft cock body, be provided with oily absorber in described oil hole, described oily absorber is posted by the gap location that forms between bearing sealed ring and bearing outer ring.

Further, described soft cock body is the oil resistant rubber plug.

Further, described oily absorber is wool felt.

Further, described oil hole entry end is provided with flat counterbore, and described soft cock body is located at the counterbore place.

Further, described oil hole is located at described bearing (ball) cover top.

Compared to existing technology, the utility model beneficial effect is as follows:

(1) simple in structure, to process easyly, cost is lower, and is easy to maintenance, is fit to scale and uses.

(2) by the injector charging-up lubricant oil, adding amount is accurate, not only saves lubricant oil, and can effectively prevent overflowing and polluting of lubricant oil in filling process.

(3) soft cock body can be after extracting injector self-closed, effectively prevent entering of dust and foreign material.

(4) oily absorber can fully absorb the lubricant oil of filling, prevents lubricant oil from bearing side leakage and contaminated equipment internal environment, and at any time for bearing provides lubricant oil, is equivalent to one small-sized " oil depot ", and lubrication effect is better.

(5) counterbore of oil hole entry end helps insertion and the location of soft cock body, can prevent that it from falling into the oil hole depths, and when hollow stud can prevent from extracting injector out, soft cock body is taken out of.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, 2, a kind of bearing oiling device, this device comprises bearing (ball) cover 2, bearing 1 both sides in bearing (ball) cover 2 are arranged with bearing sealed ring 6, be provided with oil hole 5 on bearing (ball) cover 2, be provided with soft cock body 3 in oil hole 5 ingress, in the present embodiment, soft cock body 3 adopts the oil resistant rubber plugs, (outlet end) is furnished with oily absorber 4 in oil hole 5, in the present embodiment, oily absorber 4 is wool felt, and the clearance plane that forms between wool felt and bearing sealed ring and bearing outer ring contacts.

Oil hole 5 preferred arrangement are for being located at bearing (ball) cover 2 tops, the condition that needs to satisfy is: the height of oil hole entrance is higher than the height of oil hole outlet, so be provided be beneficial to the lubricant oil that injects in oil hole along with Action of Gravity Field flows to oily absorber place, and then allow oily absorbent body lubricant oil.

Soft cock body 3 can also adopt soft stopper etc. except the oil resistant rubber plug, soft cock body 3 act as sealed oiling hole entrance and syringe needle can insert the operation of annotating.

Oil absorber 4 can also have other substitution material except being wool felt, as long as this material is loose, and porous, lipophile is good, and softness is wear-resisting, and is nonflammable, gets final product without dust.

For convenient soft cock body 3 is installed, described oil hole 5 ingress are provided with flat counterbore, and described soft cock body is located at counterbore inside, adds hollow stud and compresses.In the present embodiment, this oiling aperture is a counterbore with the oil hole coaxial arrangement, and this counter bore hole diameters is greater than the oil hole diameter.After being provided with this counterbore, soft cock body can be fixed in the counterbore place, can not fall into the oil hole depths because of External Force Acting and stop up oil hole, and hollow stud can prevent that also soft cock body from going out to come off from the oiling aperture simultaneously.
