Description

Technical Field

[0001] The present application relates to the field of bearings, and in particular to a one-piece sliding sleeve for a release bearing. Background Art

[0002] Split bearings are bearings that have their inner and outer rings separated for easier installation and maintenance. Split bearings have a one-piece sleeve structure where the inner and outer rings of the bearing are connected to a sleeve, which is used to maintain the relative position and angle of the inner and outer rings. This structure makes the bearing more stable and able to withstand greater loads and speeds.

[0003] However, since the interior of the bearing is closed, the grease needs to be injected through the lubrication holes or seals on the outside of the bearing and distributed and lubricated through the internal space of the bearing. In the existing one-piece sleeve structure, because the inner and outer rings are connected together, it is difficult for the grease to fully lubricate the entire internal space. Especially at high-speed rotation, the lubricating effect of the grease may be affected, resulting in increased friction and aggravated wear.

[0004] To this end, the present application proposes a one-piece sliding sleeve for a release bearing to solve the above technical problems. Utility Model Content

[0028] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0029] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a one-piece sliding sleeve for a separation bearing comprises a bearing body 1, wherein the bearing body 1 comprises a bearing outer ring 101 and a bearing inner ring 102, wherein a one-piece sliding sleeve 2 is arranged between the bearing outer ring 101 and the bearing inner ring 102, wherein the one-piece sliding sleeve 2 comprises a metal cylinder 201 and a sealing cover 202, wherein a plurality of interlocking grooves 3 for installing rollers are symmetrically provided on the inner and outer sides of the metal cylinder 201, and a plurality of oil storage chambers 5 are provided in the middle part of the one-piece sliding sleeve 2, wherein each of the oil storage chambers 5 is located between the interlocking grooves 3 symmetrically provided on the inner and outer sides of the metal cylinder 201, and lubricating oil holes 4 communicating with the interior of the oil storage chamber 5 are provided on the upper and lower sides of the inner sides of the interlocking grooves 3.

[0031] In the specific implementation, in this embodiment, the embedding grooves 3 are provided in plurality and are symmetrically distributed on the inner and outer sides of the metal cylinder 201 , and the embedding grooves 3 on the inner and outer sides of the metal cylinder 201 are of the same number and correspond one to one.

[0032] Cooperate with Figure 4 As shown, two horizontal oil squeezing pipes 6 are installed in the oil storage chamber 5, and the two ends of the oil squeezing pipes 6 are respectively connected with the lubricating oil holes 4 at the corresponding positions, and the two ends of the oil squeezing pipes 6 are installed with oil plugging sponge blocks 7 for plugging the lubricating oil holes 4. A movable plate 8 is arranged in the middle of the oil storage chamber 5, and a counterweight 9 is fixed in the middle of the movable plate 8. Specifically, a spring 10 is installed on one side of the middle of the movable plate 8, and the spring 10 is fixed to the middle of the inner wall of the oil storage chamber 5. The spring 10 elastically abuts the movable plate 8 toward the inner side of the metal cylinder 201, and the counterweight 9 is fixed to the side of the movable plate 8 away from the spring 10.

[0033] The two ends of the movable plate 8 extend into the middle of the two oil squeezing tubes 6 respectively, and are used to squeeze the oil blocking sponge block 7. Specifically, the middle of the two oil squeezing tubes 6 on the opposite sides are both provided with openings, and the ends of the movable plate 8 extend into the oil squeezing tubes 6 through the openings in the middle of the oil squeezing tubes 6, so that the two ends of the movable plate 8 squeeze the oil blocking sponge block 7 toward the inner side of the metal cylinder 201 under the elastic force of the spring 10.

[0034] To sum up, during the rotation of the one-piece sliding sleeve 2, the movable plate 8 will be subjected to centrifugal force to squeeze the oil blocking sponge block 7 toward the outside of the metal cylinder 201, so that the lubricating oil in the group of oil blocking sponge blocks 7 can be squeezed into the interlocking groove 3 on the outside of the metal cylinder 201 for lubrication. When the rotation force of the one-piece sliding sleeve 2 is insufficient or does not move, the spring 10 will drive the movable plate 8 to pressurize the oil blocking sponge block 7 toward the inside of the metal cylinder 201, so that the lubricating oil in the group of oil blocking sponge blocks 7 can be squeezed into the interlocking groove 3 on the inside of the metal cylinder 201 for lubrication, thereby facilitating comprehensive lubrication of the rollers and achieving good lubrication effect.

[0035] In addition, if Figure 3 As shown, an annular groove is provided at the top of the metal cylinder 201, and the annular groove is connected with the top ends of the multiple oil storage chambers 5 by providing through holes, so as to facilitate the injection of oil into the multiple oil storage chambers 5 through the annular groove, and a sealing cover 202 is embedded and fixed in the annular groove, and an embedding hole 11 is provided on the upper end surface of the sealing cover 202, and a fastening bolt 12 is arranged in the embedding hole 11, and the fastening bolt 12 is plugged and fixed to the bottom of the annular groove at the top of the metal cylinder 201, so that the fastening bolt 12 can be received in the embedding hole 11, thereby ensuring that the surface of the sealing cover 202 is level.

[0036] Working principle: The release bearing uses a one-piece sliding sleeve. When in use, the one-piece sliding sleeve 2 is rotating, and the movable plate 8 is subjected to centrifugal force to squeeze the oil blocking sponge block 7 toward the outside of the metal cylinder 201, so that the lubricating oil in the group of oil blocking sponge blocks 7 is squeezed into the interlocking groove 3 on the outside of the metal cylinder 201 for lubrication. When the one-piece sliding sleeve 2 is not rotating with sufficient force or does not move, the spring 10 will drive the movable plate 8 to pressurize the oil blocking sponge block 7 toward the inside of the metal cylinder 201, so that the lubricating oil in the group of oil blocking sponge blocks 7 is squeezed into the interlocking groove 3 on the inside of the metal cylinder 201 for lubrication, thereby facilitating comprehensive lubrication of the rollers with good lubrication effect.

[0037] At the same time, since an annular groove is provided at the top of the metal cylinder 201, the lubricating oil can be easily poured into all the oil storage chambers 5 by injecting oil into the annular groove at the top of the metal cylinder 201, and is sealed by the sealing cover 202, so that the lubricating oil can be easily replenished.

[0038] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
