The characteristics and structure of gear coupling

Gear coupling is used to connect the low speed shaft of the spindle and the reducer. This kind of lifting fittings coupling can transfer the peak torque, and can compensate the small error between the two axes, but can not ease the impact. The structure of gear coupling for lifting fittings
Gear coupling

1, 2. Outer gear sleeve 3,4. Inner ring 5,6. End cap 7,8. Seal ring 9. The connecting bolt installs the outer gear sleeve 1 and 2 on the two shaft ends respectively, and is fixed on the respective shaft by keys. The outer gear meshes with the inner ring 3 and 4 respectively. The flange of the inner ring is connected with bolts. In order to reduce the influence of the two axis axis tilt and radial displacement error, the outer teeth made of spherical shape, can be automatically adjusted, so that the load on the teeth distributed more evenly, but also reduce the burden of bearing. In this way, the torque of the low speed shaft of the reducer is transmitted to the main shaft through the outer gear sleeve, inner gear ring, connecting bolt, inner gear ring and outer gear sleeve. The coupling needs to be injected with a large viscosity and flow of lubricating grease to lubricate the teeth of the gear ring. There is a sealing device to prevent oil leakage. Press the sealing ring with end caps 5 and 6 respectively. There are oil holes 9 on the inner ring to supplement grease, and tighten the oil plug when used up.
