Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides the following technical solutions: a logarithmic roller device comprises a logarithmic roller body 1, the logarithmic roller body 1 comprises a first cylinder 2 and a second cylinder 3, one side of the first cylinder 2 facing the second cylinder 3 is provided with an embedded groove 10, one side of the second cylinder 3 facing the first cylinder 2 is fixed with an embedded block 8 matched with the embedded groove 10, the axial direction of the logarithmic roller body 1 is provided with the positioning slot 9, the positioning inserting strip 4 is inserted in the positioning slot 9, specifically, the logarithmic roller body 1 formed by the two parts can be partially replaced without being discarded integrally, thereby saving resources, secondly, when the first cylinder 2 and the second cylinder 3 are butted, the embedded block 8 can be embedded into the embedded groove 10, the butting precision of the first cylinder 2 and the second cylinder 3 can be effectively increased, then the positioning inserting strip 4 is driven into the positioning slot 9, and the first cylinder 2 and the second cylinder 3 can be stably fixed.

Further, both ends of the logarithmic roller body 1 are provided with grooves 6, oil storage tanks 7 are arranged in the positioning insertion strips 4, two ends of the oil storage tanks 7 penetrate out from the upper end and the lower end of the side wall of the positioning insertion strips 4, when lubricating oil is replenished to the bearing, part of the lubricating oil can flow into the oil storage tanks 7 from two ports of the oil storage tanks 7 to be stored, when the subsequent bearing is used, along with the rotation of the logarithmic roller body 1, the lubricating oil in the oil storage tanks 7 can be thrown out from the two ports, continuous lubrication can be carried out, oil replenishing can be carried out at intervals, frequent lubricating oil replenishing is not needed, and time and labor are saved.
