Troubleshooting the rough adjustment section of the microscope
Olympus microscope rough adjustment of the main fault is automatic decline or lifting when the tightness is not the same. The so-called automatic decline refers to the mirror tube, mirror arm or carrier stationary in a certain position, without adjustment, under the action of its own weight automatically and slowly down the phenomenon. The reason is that the weight of the mirror tube, mirror arm, carrier itself is greater than the static friction caused. The solution is to increase the static friction, so that the barrel or arm of the mirror itself gravity.
Olympus microscope for the mirror tube and most of the binocular microscope coarse adjustment structure, when the mirror arm automatically slides down, the hand can be used to hold the coarse adjustment of the handwheel on the inside of the stop pulley, both hands according to the clockwise direction of the force to tighten, you can stop the slide. If it does not work, you should find a professional to repair.
Mirror tube automatically slide, often give people the illusion that the gear and rack with too loose caused. So add shims under the rack. In this way, although the slide of the mirror tube can be temporarily stopped, but even if the gear and rack in the abnormal bite state, the results of the movement, making the gear and rack are deformed, especially when the pad is not flat, the deformation of the rack is even more powerful, the result is part of the bite of the tight, part of the bite of the loose, therefore, this method should not be used.
In addition, due to the rough adjustment structure for a long time in disrepair, lubricant dry, lift will produce uncomfortable feeling, even can hear the friction sound of the machine parts, then, can be inserted into the mechanism to clean, on the grease and then reassembled.
