Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a high-reliability bearing ring includes a ring body 1, a channel 2 is formed on an inner peripheral wall of the ring body 1, a plurality of oil injection holes 3 are formed at a top of the ring body 1, oil injection pieces 4 are connected to the inner portions of the oil injection holes 3 in a threaded manner, the ring body 1 and the oil injection pieces 4 are made of GCr15 steel, the number of the oil injection pieces 4 is four, the four oil injection pieces 4 are symmetrically distributed in a cross manner with a central axis of the ring body 1 as a center, the oil injection pieces 4 include a top cover 41 and a threaded pipe 42 disposed at a bottom of the top cover 41, a limit ring 7 for abutting against an inner top wall of the ring body 1 is disposed at an edge of one end of the threaded pipe 42 away from the top cover 41, an oil injection port 43 communicated with the interior of the threaded pipe 42 is formed on a pipe wall of the threaded pipe 42 in a length direction, a caulking groove 5 for embedding the top cover 41 is formed on the top wall of the ring body 1 corresponding to the oil injection hole 3, the caulking groove 5 is communicated with the oil filling hole 3, and cross grooves 6 matched with a screwdriver are formed in the top surface of the top cover 41.

Because the top of the ferrule body 1 is provided with a plurality of oil injection holes 3, and the oil injection piece 4 is connected with the inner threads of the oil injection holes 3, when oil needs to be filled into the bearing, the oil filling piece 4 can be screwed outwards, the threaded pipe 42 is screwed out of the oil filling hole 3 continuously until the oil filling opening 43 is exposed out of the oil filling hole 3, lubricating oil can be injected through the oil injection port 43 at this time, so that the lubricating oil flows into the threaded pipe 42 through the oil injection port 43 and flows into the bearing to complete oil injection under the action of gravity, the operation is convenient and simple, after the oil injection is completed, the oil injection piece 4 can be screwed inwards, so that the threaded pipe 42 is screwed into the oil injection hole 3 again until the oil injection port 43 is hidden in the oil injection hole 3 again, the oil filling port 43 is closed by the oil filling hole 3 so that the lubricating oil inside the bearing cannot be thrown out through the oil filling port 43, thereby greatly reducing the waste of the lubricating oil.

Because the caulking groove 5 has all been seted up to corresponding oil filler point 3 position on the roof of lasso body 1, and caulking groove 5 communicates with oil filler point 3 each other, then finish and when reseing oiling piece 4, top cap 41 can imbed inside caulking groove 5 thereupon, it is spacing to top cap 41 through caulking groove 5, can avoid the mistake to touch and lead to oiling piece 4 to be twisted, can keep the level and smooth of 1 top surface of lasso body again, thereby the result of use of bearing ring has been guaranteed, and because cross recess 6 has all been seted up on the top surface of top cap 41, then when need twist oiling piece 4 soon, can insert cross recess 6 and the application of force with the screwdriver, cross recess 6 sets up to providing the point of application of force for the operation of twisting oiling piece 4, thereby it is more light laborsaving to make when twisting oiling piece 4.

Because the limiting ring 7 is arranged at the edge of the end, far away from the top cover 41, of the threaded pipe 42, when the threaded pipe 42 is screwed to the limit, the limiting ring 7 can be abutted against the inner top wall of the ferrule body 1 to limit, so that the oil injection piece 4 is prevented from being completely screwed out of the oil injection hole 3 to cause loss, and the using effect of the oil injection piece 4 is ensured.

Because the quantity of oiling 4 is four, and four oiling 4 use the axis of lasso body 1 to be the cross symmetric distribution as the center, then four oiling 4 homoenergetic pour into lubricating oil into to can carry out evenly lubricated to the bearing, effectively guarantee lubricated effect.

Because the ferrule body 1 and the oil injection piece 4 are both made of GCr15 steel, the GCr15 steel has high hardness, high wear resistance and high heat resistance, the strength of the ferrule body 1 and the oil injection piece 4 is effectively ensured, and the bearing ferrule has high reliability.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
