Roller ring axial aligning positioning adjusting mechanism of double-roller crusher

Abstract

The invention discloses a roller ring axial aligning positioning adjusting mechanism of a double-roller crusher. The roller ring axial aligning positioning adjusting mechanism comprises a roller ring, a roller shaft, a hub and a tensioning ring. A hub shaft is axially disposed on the roller shaft. the roller ring is disposed on the hub through the tensioning ring. A gap is reserved between tensioning ring and the hub. A tensioning positioning ring is added between the roller ring and the tensioning ring. The tensioning positioning ring is provided with a positioning plane A and a positioning plane B. The positioning plane A is butted against at a radial side edge of the roller ring. The positioning plane B is butted against at a radial side edge of the hub. Axial matching faces of tensioning positioning ring and the roller ring are cylindrical. Axial matching faces of the tensioning positioning ring and the tensioning ring are conical. By the roller ring axial aligning positioning adjusting mechanism, the roller ring of the double-roller crusher can be automatically aligned and positioned during assembling, labor intensity of operators is relieved greatly, time for part replacement halting is reduced, and equipment utilization rate is increased.

Description

[0001] technical field [0002] The invention relates to the technical field of double-roll crushers, and more specifically relates to a roller rim axial alignment and positioning adjustment mechanism of a double-roll crusher. [0003] Background technique [0004] A double roll crusher is a machine in which two rollers on the same horizontal plane rotate toward each other so that materials are crushed between the two rollers. (As recorded in ZL201220324206.6 authorized by the applicant earlier) There is a gap S reserved between the two rolls of the double roll crusher, one of which is fixed, and the other roll is installed on a movable bearing seat ( That is, on the movable frame, the movable frame can move back and forth on the rack. Usually, a spring force is applied to the movable frame, that is, the movable roller body, so that the material can be effectively crushed and the crusher can be effectively protected when falling into large pieces of material or hard object...

Problems solved by technology

Therefore, during the assembly process of the roller ring 4, the axial position on the roller shaft 5 is constantly moving left and right, and it is necessary to check whether the axial position is correct during the assembly, and it is often inconvenient for the user to check these in the on-site assembly. Therefore, it is often found that the axial position of the roller ring is incorrect when the double roller body is assembled, and rework is required, which wastes a lot of manpower and time.
