The bearing housing 100 is fixed to the bearing housing bracket 200 in a snap-fit manner. All the rubber rollers rotate synchronously, in order to ensure that the rubber rollers rotate stably, after the bearing block 100 is arranged on the bearing block bracket 200, the phenomenon of autorotation of the bearing block 100 cannot occur, otherwise, the synchronous rotation of the cell culture bottle can be influenced, and the quality of cultured cells is further influenced. Other parts of the cell culture bottle rotating machine are not described in detail in the application, but the solution provided by the application cannot be considered to be realized.
The bearing seat 100 is a cylindrical structure, a through hole 120 is formed in the middle of the cylinder, a bearing mounting hole 130 connected with the through hole 120 is formed at one end of the cylinder, and a shaft end mounting hole 140 connected with the through hole 120 is formed at the other end of the cylinder. Wherein, the inner diameter of the bearing mounting hole 130 is larger than the inner diameter of the through hole 120, and the inner diameter of the through hole 120 is larger than the inner diameter of the shaft end mounting hole 140. That is, the sectional shape of the inside of the housing 100 is stepped, and according to this structure, the bearing can be conveniently installed in the housing 100, and the housing 100 can also be conveniently assembled at both ends of the rubber roller.
