Novel clamping roller for heavy rail tilter

The utility model discloses a novel clamping roller for a heavy rail tilter, which comprises a roller shaft and a roller body. The roller body comprises a roller inner barrel and a roller outer barrel; the insides of both ends of the roller inner barrel are rotationally arranged on the roller shaft by bearings; a closed lubricating oil cavity is formed between the roller inner barrel and the roller shaft; convex shoulders are formed outside both ends of the roller inner barrel; the roller outer barrel is fixedly arranged outside the convex shoulders; a radiating cavity is formed between the roller outer barrel and the roller inner barrel; a plurality of grooves are axially formed on the surfaces, which are in contact with the roller outer barrel, of the convex shoulders; the grooves are communicated with the radiating cavity. According to the utility model, the radiating effect of the clamping roller can be improved, the clamping roller works at a suitable temperature, loss of lubricating grease is reduced and the bearings are guaranteed to be well lubricated, so that the clamping roller is guaranteed to freely rotate, cost of spare parts is reduced and production efficiency is improved.
