Five principles of disassembly and assembly of helical gear reducer

The helical gear reducer is the principle that the electromotive force induced in the electric drive line is transformed into a DC electromotive force when it is drawn out from the brush end by the commutator and the commutation effect of the brush. What is the principle of its makeup? ? Let's take a brief look at it below. (1) For motors equipped with rolling bearings, the outer bearing cover should be removed first, then the fastening screws of the end cover should be loosened, and the joint between the end cover and the base shell should be marked, and the removed fastening The screws of the end cover are set in the two screw holes specially set on the end cover of the motor, and the end cover is pushed out; (2) First remove the external wiring and mark it, then loosen the foot screws and classify the motor and transmission machinery; (3) To disassemble the helical gear reducer with brush, the brush should be taken out from the brush holder, and the position of the neutral line of the brush should be marked; (4) When pulling out the rotor, care must be taken not to touch the sub-coils. If the weight of the rotor is not heavy, it can be pulled out by hand; if it is heavy, it should be lifted out with lifting equipment; (5) To disassemble the pulley or coupling on the shaft of the helical gear reducer, sometimes it is necessary to add some kerosene to the gap between the motor shaft of the pulley to make it penetrate and lubricate for easy disassembly. We should understand the five disassembly and assembly principles of the helical gear reducer, so that it will be more convenient when disassembling and assembling it, and I believe it will be more beneficial to our use.
