A drum gear coupling

Abstract

The invention discloses a drum-shaped gear coupling, the key points of the technical scheme include two inner gears, two outer gear sleeves and two end covers, and the two inner gears are connected by fasteners. Connection, the end cover and the external gear sleeve are connected by end bolts, the external gear sleeve is located inside the inner ring gear and engaged with each other, the external gear sleeve includes a shaft sleeve ring, and is sleeved on the outside of the shaft sleeve ring The inner side of the outer drum gear ring is connected with a plurality of inner protrusions in the circumferential direction, and the outer middle part of the sleeve ring is connected with a plurality of outer protrusions and inner protrusions that snap into the gaps between adjacent inner protrusions in the circumferential direction. The end is fixedly sleeved with a positioning ring, and the outer end is detachably sleeved with a dismounting ring. The positioning ring and the dismounting ring are respectively attached to the opposite sides of the outer drum tooth ring. Wavy rubber pad. When the tooth surface of the outer drum gear ring is severely worn, the end cover is removed first, and then the disassembly ring is removed, and the outer drum gear ring can be removed and replaced separately, so as to reduce the cost.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a drum gear type shaft coupling. Background technique [0002] Couplings, also known as couplings, are used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. Gears, pulleys, etc. The coupling is composed of two halves, which are keyed and fastened at the two shaft ends, and then the two halves are connected in some way. The drum gear coupling is a rigid-flexible coupling and has the ability to compensate for axial deviations such as radial, axial and angular. It has the advantages of large size, high transmission efficiency, low noise and long maintenance period. [0003] The Chinese patent with the publication number of CN205956236U discloses a drum-shaped gear coupling, which includes two left and right inner and outer gear sets that mesh with each other. and the left end cover, the left outer gear sleeve a...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned drum-shaped gear coupling is prone to severe tooth surface wear and broken teeth after long-term work, which makes it unable to use normally

However, when the coupling fails, it generally needs to be replaced in a complete set, and the cost is relatively high, which needs to be improved.
