It is a pleasure to share some practical experience with old machine clock maintenance. The following are intended to help you solve the problem safely and effectively:。
Checklist before maintenance
Before doing so, remove the following simple malfunctions and avoid unnecessary dismantling:
Power: check if the hair is full or the hammer is down。
Placing problems: ensure that the clock is hung/stabilized and vertical. Check if the bell turret touches the shell, glass or hammer。
Pointer question: see if the clockwise and the pin overlap or scrambling。
Stopping function: confirms whether the stopstick is at a “silent” or night stop。
Operation status: check if the clock is swinging normally and evenly. If it is small, the core may be dirty or lack oil。
Let's get to work
Safety first: unlocking the engine is the most important step; otherwise, when disassembled, a strong article may cause damage to the gears。
Fixed cores: the cores are attached to the pliers, or are held by hand。
Operating key: one clockwise screws the key, the other pulls out the thorn-proof claw (chip), and then turns the key half-way slowly against the clockwise。
Repeated operation: repeatedly, "twirling the thorn claws, rounding the counterclockwise, half-turning the thorn claws," until it feels completely loose。
Note: do not force the twisting of the key to avoid damage to the hairbox。
Tools and protection
Basic tools: small screwdrivers, pliers, twigs, soft brushes, balloon blowers。
Consumption materials: specialized bell oil (non-ordinary oil), precision instrument cleaners or high alcohol。
Protective: it is recommended that protective glasses be worn and that soft cloths or cardboard boxes be placed to prevent the loss of the spare parts。
Before they are removed, the whole and part of the core of the machine is taken from multiple angles, especially in the state of rods. For complex timing agencies, it is recommended that a sketch be drawn to record the location of each component, which is essential in reloading。
Core principles of cleaning and lubricants
When the clock is not maintained for many years, there are problems of slowness, pause, noise, etc., which usually means that there is a need for thorough cleaning and refuelling. Comprehensive maintenance is generally recommended every 5-6 years。
Cleaning method
Light cleaning: a soft brush and balloon can be used to clean up dust for the cores of the stains and then drop a small amount of bell oil on visible axes and friction points。
Heavy cleaning: for oil contamination and visible rust cores, all parts shall be removed. Brush it with kerosene or a special washing agent and then wash it with water and dry it completely. Note that gold plating or silver plating requires careful handling to avoid corrosion。
Lubrication point
Oil: specialized bell oil must be used and its viscosity appropriate for the low-speed, small-powered features of the clock。
Location: all points of friction, such as axle and axle holes, fork and fork, gears, etc., are dripped and overdosed to prevent the adsorption of dust to form oil sludge。
Common troubleshooting and repair
It's a little bit of a swing
Reason: obsolete or oil-deficient cores, bells rubbing on alien objects, inappropriate forklift position。
Dealing with: exclusion of placements and frictions. If this is not effective, try to adjust the length of the fork to increase the swing. If the problem remains, oil cleaning needs to be considered。
You can't go too fast
Adjustment method: the majority of mechanical clocks are slow and slow through the control of the bolts below the clock. Clockwise screws out the nut tweaks the centre of gravity up tweak the clock short tweak and walk fast。
The counterclockwise screws into the nut twirling down the center of gravity twirling the clock swing longer twirling slowly。
N. B.: usually, a round of reconciliations is about one minute per day. If the reconciliation is still not allowed, the core may be badly worn and require specialized maintenance。
Times or music functions are abnormal
Timeless/non-symphony: check if the pole is silent, whether the night stop is open, whether the packaging has not been removed and whether the reed is jammed。
An error in timing: this is usually due to the fact that the pointer was removed and wrongly loaded. The correct method is to allow the clock to walk normally, to listen to the hour at the whole point (e. G. Three clicks at three points), and then to dial the clock to the corresponding number。
Times/musical error: an attempt can be made to dial the clockwise for 12 hours to correct the switch point for the round-the-clock paper。
For the cores of the axle, which are too long to be worn, experienced players try to “crowd it”: point the edges of the worn axle at the edge of the worn axle with a pointy steel plating, tap the platinum, make the copper plywood slightly plastic, and “squeal” the worn ax. This method is more risky and may damage the plywood and is not recommended to be tried by beginners。
• important alerts and taboos: complex structures: bells with complex functions, such as spin flowers and live dolls, are very sophisticated, and unprofessionals are not allowed to break down easily。
Swifts are "hearts": spinal fractures or deformations are taboos. Very high levels of specialized technology and equipment are required for the repair or replacement of circuits, which should be handled directly by experienced teachers。
Aging parts are not hard to repair: for parts that are severely rusted or deformed, forced repair is often not possible. It would be more prudent to remove pieces from the same old bell or to reproduce them by professional masters as they are。
Values require caution: there is a high risk of self-maintenance for antique bells of antiquities or family heritage value. It is recommended to seek assessment and rehabilitation from professional institutions or experienced architects。
