Detailed Description

Fig. 3 is local schematic diagram on the left of the final drive roller, fig. 4 is local schematic diagram on the right of the final drive roller, the utility model discloses a device convenient to dismantle embedded bearing, the device include and open at least one breach 14, 14 ' to the side of recess 13, 13 ' bearing 62, 62 ' of bearing 61 bearing, and with the

same piece

10, 10 ' or 12, 12 ' of breach shape size, the piece is used for filling up the breach, and wherein breach and piece closely cooperate in order to prevent dust, and the breach is used for reserving the impetus position of demolising the bearing.

In one embodiment, the notch and the block have threads at corresponding positions to facilitate fixing the block at the notch by a screw, preferably a countersunk screw 11, 11'.

In one embodiment, the notch is square.

In one embodiment, the notch is trapezoidal.

The utility model relates to a device of embedded bearing is effectively demolishd fast under the prerequisite that does not influence YJ17 type cigarette machine feed slivering machine and send a flat belt structure main drive roller bearing dustproof effect. The bearing is time-consuming and labor-consuming when being disassembled in the past, and even the edge of the main driving roller is damaged to different degrees. In order to rapidly and effectively remove the bearing, the two square blocks are symmetrically cut at the mounting position of the main transmission roller bearing, the position of an acting point for removing the bearing is reserved, and the two square blocks are mounted back after the bearing is mounted, so that the operation and the dustproof effect of the bearing are not influenced.
