Description

Replaceable roller Technical Field The utility model relates to the technical field of rollers, in particular to a replaceable roller. Background The roller is an important consumption component for determining the efficiency of rolling mill and the quality of rolled material, and is an important part on rolling mill of steel mill, and the rolling mill steel is rolled by the pressure generated when a pair or a group of rollers roll, and is mainly affected by dynamic and static load, abrasion and temperature change during rolling. In the utility model of CN 213256273U, a replaceable roller is proposed, and the prior art and the above patent are studied to find that the existing roller needs to replace the whole roller after the hard abrasion and damage of the outer surface, and the use and maintenance costs are high. The utility model thus proposes a replaceable roll. Disclosure of Invention Technical problem to be solved The utility model aims to overcome the defects of the prior art and provides a replaceable roller. Technical proposal The replaceable roller comprises a roller body, a roller jacket is arranged outside the roller body, a mounting groove is formed in the roller body, connecting threads are formed in the mounting groove, a limit retaining ring is connected in the mounting groove in a threaded mode, a pin hole communicated with the mounting groove is formed in one side of the mounting groove, a limit pin shaft is inserted in the pin hole, a spring is connected to one side of the limit pin shaft, one end of the spring, far away from the limit pin shaft, is fixed in the pin hole, an annular limit groove is formed in the roller jacket, one end of the limit pin shaft is adaptively inserted in the annular limit groove, the pin hole and the limit pin shaft are arranged, the mounting groove and the limit retaining ring are in threaded connection, the roller jacket is sleeved on the roller body during mounting, the limit retaining ring is rotated to limit the position of the roller jacket on the roller body, the roller jacket is firmly mounted on the roller body, the roller jacket can be detached and replaced after the surface of the roller jacket is replaced, the roller jacket is convenient to use, and the cost of the roller jacket can be replaced conveniently. Preferably, one side of the limiting snap ring is fixedly connected with a buckle plate, and a second connecting thread is arranged in the limiting snap ring.
