Wearing of Bearings on Conveyor Belt:
The bearings on the conveyor belt gets worn out over time under dynamic loads leading to reduced transmission efficiency.
Solution: Mount the bearings using LOCTITE 641 Retaining Compound
Electric motors and generators are the prime drivers of all machinery. Any failure in these can lead to costly downtime. Proactive maintenance can minimize the risk of such unscheduled breakdowns and increase the service life of the motor driven equipment.
Housing and End Plates
Challenge 1: Loosening of End Plates
Vibration and shock loads can lead to loosening of the through bolts that keep the end Plates bolted to the housing. This can lead to misalignment and can cause damage to the motor.
Solution: Secure end cover through bolts with LOCTITE 222 Threadlocker
Challenge 2: Loosening of Assembly Screws and Cover Screws
The threaded assemblies can work themselves loose under dynamic loads. This can lead to excessive vibration in the machine and can damage the housing and frame.
Solution: Lock assembly and cover screws with LOCTITE 243 Threadlocker
Challenge 3: Ingression of Moisture and Foreign Particles
The interface between the end plates and housing allow foreign particles to enter the motor housing which can significantly reduce the motor performance.
Solution: Seal the end plate and housing interface with LOCTITE 518 Flange Sealant
Shaft Mountings
Challenge 1: Loosening of Bearing or Commutator
Electric motors pick up the required rotational speed with a jerk. This repeated jerk can lead to loosening of the shaft mounted component like bearing and commutator. Loosening of cylindrical fittings can reduce transmitted torque and damage the components.
Solution: Mount cylindrical components with LOCTITE 641 Retaining Compound
Challenge 2: Fretting Corrosion on Bearing
The air gap trapped between the bearing and shaft allows corrosion to build up and seize the bearing on the shaft. In such cases, the bearing will have to be replaced with a new one, resulting in downtime and scrap cost.
Solution: Fit bearings on shaft with LOCTITE 641 Bearing Retainer
Mounting Bolt
Challenge: Misalignment Due to Loose Mounting Bolts
Motor mounting bolts keep the motor frame in place and maintain alignment with the driven equipment. However, the mounting motor bolts can loose clamp loads under vibrational shocks and cause misalignment which can damage the rotational components.
Solution: Fasten mounting bolts with LOCTITE 277 Threadlockers
Most industrial centrifugal pumps carry a significant capital equipment value. It is important to extend their service lives and ensure that they run efficiently. Proactive maintenance can reduce the risk of breakdowns and increase pump reliability and longevity.
Bearing Frame & Housing
Challenge 1: Oil Leaks from Threaded Assemblies
The gaps between threads of drain plugs, oiler nipples, fittings etc. can lead to oil leaks due to constant pressure changes within the bearing housing. Not only do these leaks increase costs but also lead to the seizure of fittings and safety hazards.
Solution: Seal threaded assemblies with LOCTITE 567 Thread Sealant
Challenge 2: Bearing Spinout, Corrosion and Component Damage
Bearings are prone to spinning either on their shafts or within their housings, resulting in damage to these parts regardless of whether they have been pressed, shrunk or slip fitted in place. The gap that exists between a bearing and shaft is an area where rust can form and cause damage to the parts.
Solution: Fit and seal bearings with LOCTITE 641 Bearing Retainer
Frame Adapter
Challenge 1: Gasket Failure between Bearing Frame and Frame Adapter
Leaks from the frame connection can mean money lost in oil consumption and potential safety hazards. This happens because pre-cut gaskets cannot tackle the gap between flange surfaces. Flange imperfections are potential leak paths that pre-cut gaskets cannot seal and they relax over time to make the gaps large enough for leaks to happen.
Solution: Seal flanges with LOCTITE 518 Flange Sealant
Challenge 2: Fastener Loosening and Corrosion to Frame Adapter Mounting Bolts
Bolts are always under strain caused by torque, vibration, shock, thermal expansion and contraction. The gaps between the engaging nuts and bolts allow these external factors to challenge the clamp load.
Solution: Lock and seal bolts with LOCTITE 243 Threadlocker
Pump Casing
Challenge: Corrosion and Seizure of Pump Casing Bolts
The severe pump environments of constant temperature, pressure and humidity changes cause the pump casing bolts to corrode and seize. Seized casing bolts make pump maintenance difficult and create additional labor associated with drilling and tapping the bolt hole.
Solution: Seal and Protect Bolts with LOCTITE 243 Threadlocker
Challenge: Leaks between the Stuffing Box and Casing
The use of cut gaskets has inherent problems. Neither does it occupy all flange irregularities, nor does it maintain elasticity. This leads to creation of leak paths that corrode and damage the flange surfaces.
Solution: Seal flanges with LOCTITE 518 Flange Sealants
Coupling
Challenge: Misalignment and Damage Due to Coupling Loosening
Couplings are held in place by a key and a set screw. If the set screw loosens, the coupling can begin to slide along the shaft and disengage, or it can begin to wallow out the keyway.
Solution 1: Lock set screws in place
with
LOCTITE 222 Threadlocker (for >
¼")
Solution 2: Lock set screws in place
with
LOCTITE 243 Threadlocker (for >
¼")
Pump Base Mounting
Challenge: Misalignment Due to Loose Mounting Bolts
Vibration and possible impact shock can work to loosen the mounting bolts. Loose bolts result in a loss of clamp load, which allows the pump to lose its level and aligned configuration.
Solutions: Maintain alignment by securing mounting bolt with LOCTITE 263 Threadlocker
Industrial gearboxes play an important role in processing and manufacturing facilities. Reliable operation over a long service life, with minimum maintenance, is a key requirement. Proactive maintenance can minimize expensive downtime, enhance reliability and dramatically cut costs.
Housing
Challenge: Damage and Corrosion in Housing due to Bearing Spin
Bearing outer races are prone to spinning within their housings, resulting in damage to the housing. This damage is regardless of whether or not they have been pressed or shrink fitted in place. Once the clearance increases, the air gap leads to fretting corrosion, causing damage to the parts.
Solution: Fit bearing in housing with LOCTITE 641 Retaining Compound
Housing and Cover Assembly
Challenge 1: Gasket Failure Between Upper and Lower Housing of a Split Gearbox
Oil leakage from failed gasket between upper and lower housings of split case gearbox can increase risk of gearbox running low on oil and increase overall oil consumption, safety hazards and clean-up costs.
Solution: Seal flanges with LOCTITE 518 Gasketing Compound
Challenge 2: Loosening and Corrosion of Housing and Cover Fasteners
Cover fasteners can loosen when exposed to torque, vibration, thermal expansion and shock loads. Once the fasteners become loose, the preload on the gasket is lost and the gasket fails. Additionally, cover fasteners can corrode and seize making gearbox maintenance difficult and hence create additional labour associated with drilling and tapping of the fastener hole.
Solution: Secure cover fasteners with LOCTITE 243 Threadlocker
Lubrication and Cooling System
Challenge: Leakages from Threaded Fittings
Pressure and temperature changes within the gearbox can lead to leaks from threaded fittings such as oil drain plug, oil inlet, housing ventilation, oil pump, oil filter, oil gauge, coolant pump, pressure and temperature control unit and all pipe work.
Solution: Seal threaded assemblies with LOCTITE 567 Thread Sealant
Shaft Mounted Components
Challenge 1: Spun Bearings on Shaft
Bearings are prone to spinning on the shaft due to dynamic load on the assembly which produces axial loads higher than the original calculations. This bearing spin leads to damage on both shaft and bearing which may necessitate component replacement, causing unplanned downtime and scrap costs.
Solution 1: Fit bearings on shaft
with
LOCTITE 641 Retaining Compound (gap <
0.15mm)
Solution 2: Fit bearings on shaft
with
LOCTITE 660 Retaining Compound (gap <
