The main parts of the grinding core part of the motorized winching mill are: grinding core, movable support bracket, bushing, bearing sleeve, bearing cover, splicing cap, shaft end cover, shaft sleeve and supporting shaft, etc.
The outer diameter of the grinding core is large at both ends and small in the middle, and the taper is connected by an arc, which is connected with the output shaft of the reducer through a flat key.
The movable support bracket is composed of left and right half brackets, bracket seats, U-rings, buckles and pins. The left and right half brackets are inserted into the bracket seat slots and positioned with pins. Its function is to open the left and right half brackets when not working, so as to facilitate the loading and unloading of the wire rope. Rely on it to bear the load and unload when working.
The 211 ball bearing is installed in the bearing sleeve, cover it with the bearing cover, and cover the bearing cover with the splicing cap. The bearing is supported on the journal of the output shaft, the inner part is installed on the shaft sleeve to contact the grinding core, the outer part is equipped with a bushing, and the shaft end cover is used to locate it on the shaft.
Its working principle is: under the action of the load and the person pulling the tail rope, the wire rope is close to the grinding center and generates friction. Since both ends of the grinding core are tapered, the wire rope enters the rope along the incoming rope end on the one hand when rotating, and slides down the taper on the other hand, and exits the rope at the end of the rope when rotating and sliding (the wire rope goes out as much as the wire rope enters on the grinding core. how many ropes to ensure smooth operation of the motorized winch). The tensile force of the load acting on the grinding core is transmitted to the output shaft, and the output shaft transmits the force to the bushing (unloading sliding bearing) and 211 ball bearing, and then discharges the force to the ground through the bearing sleeve, movable support bracket, and U-shaped ring pile.
