Description

Technical Field

[0001] The utility model relates to the technical field of internal gear sleeve positioning, in particular to an internal gear sleeve positioning device of a drum gear type coupling. Background Art

[0002] The drum gear coupling is composed of an internal gear sleeve with the same number of teeth and a flange half coupling with external teeth. After the internal gear sleeve of the drum gear coupling is formed, it is necessary to drill holes evenly on its connecting surface so that the two internal gear sleeves can be locked by bolts. When drilling the internal gear sleeve of the coupling, a positioning device is required to fix it.

[0003] A Chinese patent with publication number CN216298189U discloses a positioning fixture for an internal gear sleeve of a drum gear coupling, including a fixing ring, a protective shell, a clamping spring, a clamping piece, a gear fixing piece, a spring frame and a limit spring. The utility model belongs to the technical field of positioning fixtures, specifically a positioning fixture for an internal gear sleeve of a drum gear coupling, which effectively solves the defects of most traditional positioning fixtures for internal gear sleeves of drum gear couplings on the market, such as simple functions and crude structures.
