Description

Technical Field

[0001] This utility model relates to the field of crushing machinery and equipment, and in particular to a roller ring locking device for a double roller mill. Background Technology

[0002] The working principle of a double-roll mill is that a motor drives the main shaft to rotate, and the main shaft drives the rollers to rotate via a key and hub, thereby crushing the stone material that enters the crushing chamber between the rollers. Traditional double-roll mills have complex roller fastening devices that are inconvenient to assemble and disassemble. Summary of the Invention

[0003] To solve the above problems, this utility model provides a roller ring locking device for a double roller mill.

[0004] The technical solution adopted in this utility model is as follows: the roller ring locking device of the roller mill includes a hub, a roller ring, a flat key, and a main shaft; the hub has two symmetrically arranged flanges; the hub has a keyway in its inner hole; the roller ring is a hollow structure, and the roller ring has grooves and groove slopes on both sides, and a flange inlet is opened at the hole position on each side of the roller ring; the main shaft has a shoulder; a keyway is opened on each side of the shoulder of the main shaft; there are two hubs and two flat keys; the two hubs are respectively fixed to the main shaft by the flat keys; the flanges enter the grooves formed by the groove slopes through the flange inlets, and the flanges are locked in the grooves; the roller ring is locked on the hub by rotating the hub through a certain angle.

[0005] The beneficial effects of this invention are as follows: Using the aforementioned roller ring locking device for the double-roll mill, simply insert the hub flange into the predetermined position through the flange inlet, and then rotate it a certain angle to lock the hub flange and the roller ring groove. During operation, the hub rotates in the same direction as the locking roller ring, while the roller ring resistance is in the opposite direction, preventing the hub and roller ring from becoming loose during operation. When replacing the roller rings, simply reverse the left and right roller rings and bring them close together to loosen them for easy replacement. Attached Figure Description

[0014] The roller ring locking device of the roller mill includes a hub 1, a roller ring 2, a flat key 3, and a main shaft 4. The hub 1 has two symmetrically arranged flanges 5. The hub 1 has a keyway in its inner hole. The roller ring 2 is a hollow structure, with grooves 6 and groove slopes 8 on both sides. Each side hole of the roller ring 2 has a flange inlet 7. The main shaft 4 has a shoulder. Each side of the shoulder of the main shaft 4 has a keyway. There are two hubs 1 and two flat keys 3. The two hubs 1 are fixed to the main shaft 4 by the flat keys 3. The flanges 5 enter the grooves 6 formed by the groove slopes 8 through the flange inlets 7, and the flanges 5 are locked in the grooves 6. The roller ring 2 is locked to the hub 1 by rotating the hub 1 by a certain angle.

[0015] When using the roller ring locking device of the roller mill, the rotation direction of the hub 1 is the same as the rotation direction of the locking roller ring 2, so that the hub 1 is locked on the roller ring 2 and will not come loose; when it is necessary to replace the roller ring 2, the two roller rings 2 are reversed and brought close to each other, so that the two roller rings 2 can be loosened for replacement.

[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
