Gear type coupling inspection and maintenance

Gear type coupling there are as many as hundreds of varieties, but the basic form is two kinds: 1, the internal and external tooth combined with type;2, end face gear combination.Other forms are based on these two kinds of deformation.Combination within the outer tooth clutch transmission torque is bigger, designed to take into account the different needs of users, intentionally designed to be in the shaft end on both sides of the tooth length, so that the user can choose according to need to install the direction.So, there is no rule which end toward where.When installation should pay attention to: 1, if be the original equipment replacement, so often and original in the same direction, if is the new design and manufacture of equipment, then to not have interference with other parts around the premise that the inside and outside the principle of tooth surface the more the more reliable installation.

Gear Type coupling maintenance generally in accordance with the following methods: 1, check the coupling tooth surface meshing, the contact area along the tooth height not less than 50%, along the tooth width is not less than 70%, tooth surface can not have severe pitting corrosion, abrasion and crack.2, coupling gear ring all round beating is greater than 0.03 mm, not face round beating is not greater than 0.02 mm.3, if must remove the gear ring, have to use special tool, do not knock, lest make the shaft bending or damage.When the back pack, gear ring should be heated to 200 ℃ or so and then loaded on the shaft.Outside of the ring gear and shaft are generally 0.01 ~ 0.03 mm.4, back in indirect tube or other components should be in accordance with the original tags and data fitting.5, with a torque wrench to tighten the bolts evenly.
