Abstract
The invention discloses a bearing end cap seal device. The bearing end cap seal device comprises an oil slinger A, an oil slinger B and an outer end cap, wherein the outer end cap is fixedly arranged on a bearing end cap, a seal inner cavity is formed between the outer end cap and the bearing end cap, the oil slinger A and the oil slinger B are perpendicularly arranged, a seal ring is mounted between the oil slinger A and the oil slinger B, the oil slinger A, the oil slinger B and the seal ring are arranged on a main shaft in a sleeving manenr, and the oil slinger A, the oil slinger B and the seal ring are all arranged in the seal inner cavity. The structure is novel, and the design is reasonable. A great seal effect is realized through arranging the oil slinger A and the oil slinger B and arranging the seal ring between the oil slinger A and the oil slinger B, so that not only is the oil leaking possibility reduced, but also the work environment of the unit is improved. The manufacture is simple, the cost is relatively low, leaked oil is conveniently guided into the seal inner cavity through an oil outlet arranged, and the service life is prolonged.
Description
Technical field
The invention belongs to bearing component technical field, be specifically related to a kind of bearing end cap seal device.
Background technique
Along with the development of science and technology, various machinery equipment obtains a large amount of utilizations, a large amount of mechanical structure finds application, the bearing one that has been exactly the most frequently used, bearing is component conventional in mechanical rotation, in order to prevent lubricant oil spill with bearing in the middle of enter the wearing and tearing that dust causes bearing, frequent meeting arranges bearing (ball) cover at bearing end, horizontal unit sliding bearing lubricating great majority adopt thin oil lubricant, lubricant oil is lubricating bearings under the drive of food tray, therefore required lubricant oil is many, oil level is higher, end cap gas leak of the oil leakage is hard nut to crack, particularly high rotating speed bearing, conventional structure adopts maze-type structure and hair felt ring seal, the gap length of labyrinth seal and main shaft can affect sealing effect, gap is little, good sealing effect, but easily damage oil sealing, the large easily leakage of oil in gap, unit bearing be in operation leakage of oil or oil gas phenomenon comparatively serious, unit base plate oil stain is obvious.The sealing of felt circle was lost efficacy because being full of oil in use for some time.
Summary of the invention
For problems of the prior art, the object of the invention is to design provides a kind of bearing end cap seal device.
Described a kind of bearing end cap seal device, comprise disc A, disc B and outer end cap, described outer end cap arranges and is fixedly installed on bearing (ball) cover, it is characterized in that the closed cavity formed between described outer end cap and bearing (ball) cover, disc A and disc B are vertical setting, be provided with seal ring between described disc A and disc B, described disc A, disc B and seal ring are all enclosed within main shaft, and described disc A, disc B and seal ring are all arranged in closed cavity.
Described a kind of bearing end cap seal device, together with is characterized in that described disc A is bolted with disc B.
Described a kind of bearing end cap seal device, is characterized in that the bottom of described outer end cap has oil drainage hole.
Novel structure of the present invention, reasonable in design, by the seal ring arranging disc A and disc B and be arranged between the two, realize good sealing effect, namely the probability decreasing leakage of oil which in turn improves the working environment of unit, and manufacturing simple, cost is lower, by the oil drainage hole arranged, be convenient to oil spill to lead back closed cavity, add working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, a kind of bearing end cap seal device of the present invention, comprise disc A1, disc B2 and outer end cap, outer end cap 3 arranges and is fixedly installed on bearing (ball) cover 4, the closed cavity formed between outer end cap 3 and bearing (ball) cover 4, disc A1 and disc B2 are vertical setting, are provided with seal ring 5 between disc A1 and disc B2, disc A1, disc B2 and seal ring 5 are all enclosed within main shaft 6, and disc A1, disc B2 and seal ring 5 are all arranged in closed cavity.Disc A1 and disc B2 is linked together by bolt 7.The bottom of outer end cap 3 has oil drainage hole 8.
Be specially, disc A1 and disc B2 is two points of half, namely disc is divided into two along a certain diameter, and then trap is on main shaft 6, and point demifacet of disc A1, disc B2 is orthogonal, namely disc carry out point half along diameter orthogonal, make two discs overcome centrifugal force when rotating along with main shaft 6 and can not depart from.By installing seal ring between disc A1 and disc B2, disc can be rotated with main shaft 6, and make in the middle of two discs oil-proof, disc has the effect of reverse oil pump, effectively can prevent leakage of oil, but also by described oil drainage hole 8, leakage of oil can be led back closed cavity, strengthen sealing usefulness.
Claims (3)
1. a bearing end cap seal device, comprise disc A, disc B and outer end cap, described outer end cap arranges and is fixedly installed on bearing (ball) cover, it is characterized in that the closed cavity formed between described outer end cap and bearing (ball) cover, disc A and disc B are vertical setting, be provided with seal ring between described disc A and disc B, described disc A, disc B and seal ring are all enclosed within main shaft, and described disc A, disc B and seal ring are all arranged in closed cavity.
2. as right and a kind of bearing end cap seal device requiring as described in 1, together with it is characterized in that described disc A is bolted with disc B.
