Detailed ways

Example 1

Please refer to Fig. 1-Fig. 2, the present application provides a kind of roller crusher, comprises support frame 1, driving motor 2, drive roller 3 and driven roller 4, and drive motor 2 is installed on one side of support frame 1 through motor seat On the upper side, the driving roller 3 is rotatably mounted on the inner side of the support frame 1 through bearings, and the driven roller 4 is opposite to the driving roller 3 . The driving gear 9 is meshed with the driven gear 10, the output end of the driving motor 2 is connected with the driving gear 9 and the driving roller 3 through the driving shaft 11, and the driving gear 9 is connected with the driving shaft 11 by a key connection. The driven gear 10 is connected to the driven roller 4 through a first multi-link coupling 12 . The maximum adjustment distance of the first multi-link coupling 12 is 180 mm. The driving motor 2 is preferably set as a permanent magnet motor, which is more energy-saving and power-saving than other types of motors.

It should be noted that: the drive shaft 11 itself can be connected as a whole, or can be divided into three short shafts, respectively short shaft one 11a, short shaft two 11b, short shaft three 11c, short shaft one 11a and short shaft two 11b Connected by common shaft coupling 21, short shaft one 11a is used as the drive shaft of drive motor 2 itself, short shaft two 11b is used to be connected with driving gear 9, and short shaft three 11c is used as the roller shaft of driving roller 3, like this, can make The overall loadable moment is higher.

The inner side of the support frame 1 is slidably provided with two vertical boards-5 placed oppositely, and a slideway 15 is provided below the two vertical boards-5, and the cross-sectional shape of the slideway 15 is identical to that of the vertical board-5. During concrete setting, slideway 15 can be set to rectangle, dovetail groove shape, trapezoid etc. A bearing seat 17 and a bearing seat 2 18 are arranged between the two vertical plates one 5 . The first bearing 16 is arranged in the first bearing seat 17, and the second bearing 19 is arranged in the second bearing seat 18. The first bearing 16 is used for installing the driven roller 4 , and the second bearing 19 is used for installing the driving roller 3 . The slideway 15 is used to adjust the initial gap between the driving roller 3 and the driven roller 4 . Bearing seat one 17 is used to adjust the movement gap between the driving roller 3 and the driven roller 4 during the crushing process.

Referring to Fig. 1 and Fig. 2, bearing seat 1 17 is connected with an adjustment mechanism, and the adjustment mechanism includes a fixed plate 201, an adjustment screw 202, a limit screw 204 and a vertical plate 2 203, and the vertical plate 1 5 on the right side and the vertical plate 2 203 Elastic pieces 205 are provided therebetween.
