Abstract
The utility model provides a tension roller for a semi-feeding reaping machine threshing chain, belongs to the technical field of agricultural machinery, and particularly relates to a tension roller for a reaping machine threshing chain, which includes a cylindrical roller, wherein a cylindrical through hole is arranged at the center of the roller; and a bearing is fixedly arranged in the through hole. The utility model adopts one roller, and the bearing is arranged in the roller, so that the operation is flexible and the dissipation is small when the roller is contacted with a shaft; and the two rollers of the prior art are designed to be one roller, thereby enlarging the contact area with the chain, reducing the abrasion, prolonging the service life of the roller and achieving more stable operation.
Description
Technical field
The utility model belongs to the farm machinery technical field, is specifically related to the tension roller that a kind of harvester threshing chain is used.
Background technique
Existing half-feeding harvester threshing chain tension roller is generally two narrower rollers, directly is enclosed within on the axle, because and do not have bearing between the axle, it is dumb to cause tension roller to rotate, and long-time running damages easily; And the surface of contact of roller and chain is little, and is big to the wearing and tearing of chain, the working life of also having reduced roller and chain simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of tension roller of long service life.
The utility model comprises a cylindrical roller, and the center of described roller is provided with cylindrical hole, and described through hole internal fixation is provided with bearing.
The utility model is single roller, and bearing is set in roller, and is coupling when touching, and goes slick, and loss is little; And it is original two roller design are become one, increased the area of contact with chain, reduced wearing and tearing, improved the working life of roller, and more steady during work.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, half-feeding harvester threshing chain tension roller comprises a cylindrical roller 1, and the center of roller 1 is provided with cylindrical hole, and the through hole internal fixation is provided with bearing 2.
Claims (1)
1. half-feeding harvester threshing chain tension roller, it is characterized in that: comprise a cylindrical roller, the center of described roller is provided with cylindrical hole, and described through hole internal fixation is provided with bearing.
