The utility model discloses a rod-toothed coal crusher. The coal crusher comprises a base, a shell, a motor, a water pump and a water pipe, wherein the shell is fixedly welded on the base; the motor is fastened on the top of the shell; a driving wheel is fixed on the output shaft of the motor; a coal inlet is communica...
Conventionally, the step motor moves the mechanism or at one second intervals: play needed between the gear teeth makes the continual stop-and-start somewhat noisy. To quieten the action, rubber(covered)gears are used. A form more economical to mfr. is here provided, in which the gear driven by the step motor pinion is...
The device allows vibration frequency to be varied, and comprises a body anchored at one point, with a constant width slot in it in which a peg can be slid. The peg has a cylindrical section with peripheral teeth, meshing with a rack formed along one side of the slot, while it is frictional contact with the other side,...
