A enormous total of technological bearing facts and course of action is available by most bearing companies. If you are like me, you simply just do not have the time, endurance, or interest, in wading by way of all of this info, with cost effectiveness getting unsupported by the frequent will need to outsource bearing routine maintenance, but yet do have an fascination in operating cost reduction for your tree stump grinder. Substitute bearings cost above £100 each, and depict a massive part of overall machine servicing expenditures. This information is meant for these who want to lessen cost by rising bearing service lifetime. Bearing failure or untimely bearing use on stump grinders is largely thanks to insufficient upkeep of cleanse lubricant. I use a pneumatic grease dispenser pushed by an air compressor at each and every times close of stump grinding, with a grease top rated up, out in the discipline, making use of a typical hand-held grease pump. I use a terrific offer of grease but it is far cheaper than replacement bearings. When I re-grease bearings, I extensively purge out the contaminated grease, until finally cleanse grease exudes from the bearing. A superior melting point EP-2 grease is critical. I want a molybdenum disulphide (moly) enriched EP-2 intricate grease for the reason that it is a large-obligation grease. So, to sum up this paragraph, there are a few ideas of maximizing bearing existence insofar as lubricants are involved:
- choose the proper grease
- apply the right grease properly e.g in the proper quantity
- re-grease commonly
A 2nd typical rationale for premature bearing wear on stump grinders is inadequate or incorrect bearing adjustment ( for all those machines with an adjustable bearing wear takeup) Now, I know how uncomfortable accessing bearings for adjustment, can be on stump grinders. I made up some specialised resources out of allen keys, owing to their tricky, higher high quality steel written content, as a do the job all around to the uncomfortable obtain dilemma I have on my grinder. I merely ground absent excess materials with a bench grinder to condition an allen vital into a ideal-angled punch. If you are comfortable undertaking this, be sure to be absolutely sure to frequently cool the allen critical in drinking water. Do not allow it turn blue in colour. I arrive from an engineering history, and acknowledge that many who might read through this, do not. Numerous may come to feel this to be somewhat out of their depth. This is why I am making this effort and hard work to stay clear of technicalities as substantially as feasible with emphasis on minimum salient factors. I am not conversant with bearing entry configurations on all brands of stump grinders, but I are unable to over emphasis how, with a little bit of initiative and willpower, the importance to prevail over a bearing access challenge is. It will save you income.
The detection and assessment of untimely bearing failure is by its character a technological topic involving specialised devices e.g. warmth sensors, vibration sensors, infrared sensors, oil and ultrasound examination tools. All of this equipment generates a terrific deal of information, is extremely high-priced, and fully impractical out in the discipline. A non technical tree stump grinder who is dependent on the continuous procedure of his stump grinding machine will conveniently be set off by this predicament. The least difficult, most useful and non technological way to about observe bearing efficiency is to relaxation your hand on the pillow block bearing soon after managing it for a acceptable duration of time, say at minimum 1 hour. If you should remove your hand for the reason that the bearing is as well very hot, this suggests a worn bearing. Adjustment to consider up excessive engage in within just the bearing be made in accordance with manufacturers guidance. If the seem of a bearing “knock or rumble” is also heard, this usually indicates it is excessively worn and demands substitution. For individuals who my be interested, there are 4 levels of bearing failure which I will touch on, as it does get included and is not in retaining with this scope and its objective.:
- Stage 1. Vibration evaluation detects the earliest signal of bearing failure. Signal information appears in the ultrasonic frequency selection band all around 250 to 350 Kilo Hz.. At this stage there is about 10-20 % remaining bearing lifetime.
- Phase 2. Bearing failure begins to “ring” at its purely natural frequency (500 – 2000 Hz) At this stage there is 5 to 10% bearing everyday living remaining.
- Phase 3. bearing failure harmonics are clear with defects in the interior and outer races. Temperature increase is now obvious with 1 to 5% bearing daily life still left
- Phase 4. Superior vibration is apparent with random ultrasonic sounds greatly greater, temperature raises speedily. A person hour to 1 p.c remaining lifestyle.
It is unfortunate for all stump grinder operators, that by the time a bearing knocks, rumbles, or significantly heats up, it is shortly on its way to failure. There is no functional way for the ordinary operator / operator to precisely decide the size of serviceable time remaining in a stump grinders bearing though out in the field.
From this viewpoint, I am building an try to check out to obtain some useable facts out in the industry, which may perhaps demonstrate to be a functional and affordable way to watch bearing serviceability. I will be putting in thermocouples (warmth sensors) to the bearings. If a operating regular temperature gradient can be set up, it could prove beneficial to all those stump grinders who are anxious with maximizing their devices bearing lifestyle, by basically changing up their bearings, when its temperature rise suggests time to do so. This will require some work on the section of all those intrigued. They much too will need to have to match thermocouples to their bearings to monitor temperature as the only cost-successful, and practical way to know when to change up their bearings.
This exertion will be absolutely negated if a rigorous and ample re-greasing system is not maintained. What would be the issue of typical, timely, bearing changes, if the bearings consistently ran in a mattress of contaminated grease. I believe the reader will concur, is a full waste of time and effort.
