How to troubleshoot microscope coarse adjustment
Microscope Rough adjustment of the main fault is automatic decline or lift the tension is not automatic decline refers to the lens barrel, mirror arm or carrier table resting in a position, without adjustment, in the microscope itself under the action of the weight of the phenomenon, automatically and slowly fall down. The reason is that the mirror tube, mirror arm, the carrier itself is greater than the gravity of the static friction caused by the table. The solution is to increase the static friction, so that it is greater than the gravity of the mirror tube or mirror arm itself.
For the microscope oblique cylinder and most of the binocular microscope coarse adjustment mechanism, when the mirror arm automatically slides down, can be used with two hands respectively to hold to the coarse adjustment of the handwheel on the inside of the stop pulley, both hands according to the clockwise direction of the tightening force, you can stop the slide. If there is no effect, you should find a professional repair.
Microscope The barrel of the microscope automatically slide, often mistakenly thought to be gear and rack with the too loose caused by. So in the rack under the shims. In this way, although the microscope tube slide can be temporarily stopped, but it makes the gear and rack in the abnormal bite state. As a result of the movement, the gear and rack are deformed. Especially when the pad is not flat, the deformation of the rack is more powerful, the result is part of the bite is tight, part of the bite is loose. Therefore, this method should not be used.
Microscope Rough adjustment mechanism due to long time out of repair, lubricant dry, lift will produce uncomfortable feeling, and even can hear the friction sound of the machine parts. At this point, the mechanism can be removed and cleaned, reassembled after greasing.
