2 Mount Selection Why consider a Mounting System? Mounting systems support a machine or component within a machine, and are intended to reduce the adverse effects of vibration/shock/noise that is mechanically transmitted from something that is creating vibration, shock loads or noise to something that could adversely be affected. igure 1 shows this graphically. M1 is vibrating due to unbalance or some oscillating motion igure 1 M2 would be adversely affected if connected directly to M1 Mounts K1 provide a resilient connection that permits relative motion. What an You xpect rom Mounting System? reater sales appeal for your product or better performance for your in-plant machine: a. helping it run smoothly and quietly b. extending its reliable service life c. improving its accuracy d. reducing its maintenance requirements e. lowering its cost by accommodating misalignment and reducing stress f. replacing operator fatigue with comfort Kgs Lbs N ow to Select the Mounting System that will Satisfy Your Requirements. irst, identify your requirements: a. Weight to be supported at each mounting point. xample: 16 kgs. (35lbs) [157N] total assume 4 mounting points therefore 4 kgs/mount (8.75 lbs / mount) [39.2N / mount] and centre of gravity at geometric centre. b. Vibration frequency of the disturbing machine. f this information is not readily available, here are some suggestions; 1. Vibration is frequently caused by inbalance of rotating members. machine with an 1800 rpm motor will most likely be vibrating at 1800 cpm or 30 z (cps) 2. Selection of mounts for engines should be based upon lowest operating speed. 3. mounting system that isolates the lowest frequency vibration also isolates all higher frequencies. c. etermine isolation efficiency required. f this is not given and you have no basis for arriving at a value, start with 75% isolation efficiency. This would mean 25% of the disturbing vibration force or amplitude would be transmitted (T) to the isolated unit. This Value is reasonable and generally acceptable. Second, alculate required Natural requency: d. alculate required natural frequency and static deflection for mounts for fd = 30z and T = 0.25 Third, determine required static deflection or spring rate: e. Static deflection (ds) for this natural frequency is calculated with the formula ds = / fn is a constant (9.80/ fn is a constant) /(13.42) = 1.4mm (9.80/(13.42) = in.) f. Mount data sheets sometimes list spring rate rather than static deflection. Required spring rate (K) can be calculated as follows; K = load (kgs)/ static deflection. or [= load (N) / static deflection.] or (=load (lbs) / static deflection) = 4 kg/ 1.4 mm [= 39.2 N / 1.4mm] (= 8.75 lbs / in) = 2.85 kg/mm [= 28 N/mm] (= 160 lbs/in) ourth, Select mounts: g. Select style of mount desired. h. Select mount that has load capacity equal to or greater than calculated value. ifth, determine isolation efficiency: i. Mounts are not always available with the right combination of load capacity and static deflection or spring rate. Overloading mounts is not recommended. Underloaded mounts will produce less static deflection and not isolate as well. igure 2 will help you determine the isolation efficiency you can expect. irst, calculate actual static deflection (das) for mount based on actual load compared to rated capacity. das = ds x (actual load/rated capacity) Refer to igure 2, the isolation efficiency can be determined by tracing vertically along the static deflection axis to the disturbing frequency (30 z) horizontal line. The percent reduction in vibration is shown by the diagonal line (75%). solation fficiency: igure 2 fd - isturbing re igure 2 can also be used to arrive at the required static deflection by starting with the disturbing frequency. ind the point where the disturbing frequency and desired percent reduction in vibration line intersect. The vertical line passing through this point is the required static deflection to produce the desired vibration isolation efficiency of the disturbing frequency. 1 etermine fd (disturbing frequency) 2. ecide on required fd solation fficiency isolation efficiency 3. Vertical line from point of intersection is required - ds (static deflection) and fn (natural frequency) Ks (Spring Rate) = supported load required static deflection Static eflection Natural requency Vibration ontrol 41

20 Washers Washers washers provide an interlocking system of metal parts which act to prevent damage from overload or excessive shock impact. Load eflection haracteristics 1. ach mounting has definite load rating. orrect loading is essential to allow movement in free shear between snubbing washers. 2. Rated deflection is a predetermined value in mounting design. When a mount is supporting to its rated load, the resulting deflection positions the mount midway of the zone of free shear action. 3. Zone of free shear action is the distance through which mounting may oscillate without restriction in free shear between snubbing washers. 4. curve illustrates rapid increase in spring rate of mounting which occurs when upper snubbing washer contacts rubber under overload or shock. ncrease in spring rate limits deflection and arrests excessive movements. 5. Rebound curve illustrates increase in spring rate when the bottom snubbing washer contacts rubber under overload or shock. This increase in spring rate restricts movement in the same manner but in the opposite direction as described for the snubbing curve above. 6. ree deflection curve defines action which takes place when a shock load is imposed on a non-snubbing mounting. eflections under shock in both directions would be very large and in proportion to load imposed. 4 urve Washer Washer Washer 1 Rated Load LO 6 ree eflection urve (without snubbing) Rated eflection LTON 5 Rebound urve 3 Zone of ree Shear ction Washer Washer Washer Washers Ø Part No. O () () Thickness () Used With mm mm mm nglish Metric Mount Series (T = Tail Washer, = ead Washer) J /8.

Operation up to 7000 rpm is permitted with reduced misalignment. or speeds above 4000 rpm, shielding is required and/or balancing of assembly may be required. ynaflex LR Type ouplings Ø Ø Ø 66.0 typ Part No. Torque Rating Static Torsional Rate Lbs-in N-m lbs-in/ rad N-m/ rad LR LR LR LR Permissible Misalignments xial Rate Radial Rate Part No. ngular xial Parallel lbs/in N/mm lbs/in N/mm deg in mm in mm LR / / LR / / LR / / LR / / Part No. No of inserts ia ole ia oupling O oupling Len Len mm mm mm mm mm mm LR LR LR LR Vibration ontrol 61

23 ouplings ynaflex L Type ouplings The ynaflex coupling line has been developed to overcome numerous torsional problems associated with vehicle and industrial driveline systems. These couplings increase equipment life by protecting against torsional vibration, shock and misalignment. These couplings are fitted as original equipment to many brands of vehicles such as ase, aterpillar, uclid itachi, ngersoll Rand, Komatsu and Terex. eatures and enefits: apacity of 75 to 1000hp at 2000rpm Torsional Vibration isolation and protects against torsional shock loads.
