Abstract
The utility model relates to a bearing currying head, including currying head body, currying head body is a T type structure, be provided with internal diameter guide face, currying locating surface and sealed face on the currying head body, locating surface and sealed face be provided with a plurality of notes fat holes, notes fat hole site in bearing inner race between terminal surface and the holder section. After having adopted above -mentioned structure, bearing the currying in -process can be more accurate flow the grease between outer ring raceway and kingpin, form the lubricant film. The effective content of grease in the bearing is installed and use can be guaranteed to this kind of currying effect, makes the bearing have fine lubricated state, has ensured the life of bearing.
Description
Technical field
This utility model relates to technical field of bearing processing, especially relates to a kind of needle bearing grease-adding head.
Background technology
In prior art, needle roller bearing without inner ring is in stuffing, owing to there is no clear and definite regulation, traditional method only notes the degree of accuracy controlling stuffing amount, and ignore the position of oil addition, therefore general grease-adding head only with bearing in the middle part of opposite position is carved with grease injection hole, therefore substantial amounts of oils and fats is attached on bearing needle endoporus, retainer inwall, a small amount of from entering raceway between needle roller and fenestra, as shown in Figure 3.The oils and fats of this kind of form can be engaged axle in installation process and take out of in a large number so that the actually used amount of oils and fats reduces and cause the waste of oils and fats, and oils and fats only exists and is rolled into and could form effective tempered oil film between needle roller and play lubrication.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel grease-adding head, solves to cause Problems existing in stuffing, makes oils and fats be formed and forms effective lubricating function between raceway and needle roller, reduces the waste of oils and fats.
The technical scheme in the invention for solving the technical problem is: a kind of needle bearing grease-adding head, including grease-adding head body, described grease-adding head body is a T-type structure, described grease-adding head body is provided with internal diameter guide surface, stuffing locating surface and sealing surface, described locating surface and sealing surface are provided with multiple greasing hole, described greasing hole is between bearing outer ring inner face and retainer section so that oils and fats can accurately flow between raceway and needle roller.
In one preferred embodiment of this utility model, described internal diameter guide surface inserts in bearing inner race, and described stuffing locating surface is fitted with needle roller end face.
In one preferred embodiment of this utility model, described sealing surface seals laminating with bearing outer ring outer face.
In one preferred embodiment of this utility model, described grease-adding head body also offers a notch cuttype oil groove, and described notch cuttype oil groove and greasing hole are criss-cross construction.
This utility model provides the benefit that: after have employed said structure grease-adding head, decreases the loss of oils and fats.The rational stuffing mode of needle bearing, it is ensured that the content of oils and fats in bearing use, eliminates the defect covered with oils and fats on bearing bore diameter, it is ensured that the lubricating reliability energy of bearing, improves the service life of bearing.Eliminate tradition stuffing and can only be added in the bad phenomenon between bearing bore diameter and retainer inwall.
Accompanying drawing explanation
Fig. 1 is grease-adding head internal structure schematic diagram of the present utility model；
The oils and fats that Fig. 2 is in this utility model stuffing flows to schematic diagram；
Fig. 3 is that in traditional grease-adding head stuffing, oils and fats flows to schematic diagram；
In accompanying drawing, the labelling of each parts is as follows: 1, grease-adding head body；10, notch cuttype oil groove；11, internal diameter guide surface；12, stuffing locating surface；13, sealing surface；14, stuffing hole；2, bearing；3, retainer.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining.
Refer to shown in Fig. 1 and Fig. 2, needle bearing grease-adding head, it is characterized in that: include grease-adding head body 1, described grease-adding head body 1 is a T-type structure, described grease-adding head body 1 is provided with internal diameter guide surface 11, stuffing locating surface 12 and sealing surface 13, described locating surface 12 and sealing surface 13 are provided with multiple greasing hole 14, and described greasing hole 14 is between bearing outer ring inner face and retainer section, and oils and fats flows into bearing from stuffing hole 14 under the effect of the pressure.
Furtherly, described internal diameter guide surface 11 inserts in bearing inner race, and described stuffing locating surface 12 is fitted with needle roller end face；Described sealing surface 13 seals laminating with bearing outer ring outer face；Described grease-adding head body also offers a notch cuttype oil groove 10, and described notch cuttype oil groove and greasing hole 14 are in criss-cross construction.
When grease-adding head that this utility model is arranged on grease-adder is descending, internal diameter guide surface 11 enters centering in bearing, stuffing locating surface 12 is after grease-adding head is axially positioned by benchmark according to needle roller end face, greasing hole 14 can be positioned at the gap between bearing 2 outer ring inner face and retainer 3 section accurately, oils and fats is made to can be good at flowing between bearing outer ring ball track and needle roller from notch cuttype oil groove 10 by greasing hole 14, seal face 13 prevents oils and fats excessive under stress, can effectively to bearing lubrication by this kind of method stuffing, reduce the waste of oils and fats, improve the greasy property of bearing.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
