Abstract
The utility model discloses a belt tension device which comprises a frame body which is composed of two fixed plates, wherein the middle part of the frame body is provided with a fixed shaft, the tail end of the frame body is fixedly provided with a rotating shaft sleeve on which a tension wresting spring is arranged and the front end of the frame body is provided with a tension wheel. The tension wheel comprises a wheel shaft, wherein both ends of which are arranged on the frame body and a shaft bearing arranged on the wheel shaft. A tension wheel body is arranged on the shaft bearing. An installing groove of an outer ring of the shaft bearing is arranged on the tension wheel body. A block ring is arranged between the fixed plates of the frame body and an inner ring of the shaft bearing. The installation of the shaft bearing with the structure is simple. The wheel shaft does not need a shaft shoulder, which is convenient to process the wheel shaft. The contact area of the rotating shaft sleeve fixedly arranged at the tail end of the frame body and a rotating shaft is larger, and the service life of the utility model is extended.
