Summary : Lanphan analyzed the possible failures of mechanical fairground rides, also put forward the handling methods and prevention measures for your reference.

In recent years, large-scale mechanical rides developed in a rapid speed, especially in all kinds of amusement parks, more and more mechanical rides are seen everywhere. Affected by various factors, large mechanical fairground rides may come across operational failures. Thus, Lanphan analyzed the possible failures of mechanical fairground rides, also put forward the handling methods and prevention measures for your reference.

Operational Failure
Cause
Handling Method
Mechanical fairground rides chain shake.
Chain become loose, overload, one or more chain link not flexible.
Install chain tensioning gear, reduce loading or adjust center to center spacing. 
Mechanical fairground rides chain plate tired.
Overload, it may generate tiny crack, even has fracture. 
Reduce load or change a higher carrying capacity chain.
Mechanical rides sprocket abrasion.
If both sides of sprocket has obvious abrasion, that may caused by transmission alignment failure.
If fairground rides was abrased seriously, please change a new sprocket wheel or install sprocket wheel in opposite way to make light abrased side face to chain.
Hinge pin abrasion of the fairground rides.
Lack of lubrication.
Please frequently check if there are grinding material in lubricating oil, or change lubrication way.
Chain and chain wheel doesn’t match well.
Chain hinge abrasion, pitch extension.
Change a new chain.
Scraping belt side grinding.
Transmission alignment failure.
Check alignment of axle and sprocket wheel. Otherwise, it may caused by overloading.
Pin roll agglutination of fairground rides.
Lack of oil supply.
Check the installation condition of axle and sprocket wheel.
Abnormal chain tension of mechanical rides.
Improper droop distance.
Adjust the droop distance.
Fairground rides chain running noise is too loud.
Possible causes: improper chain tightness, lack of lubrication, abrasion or oversize chain pitch.
Adjust center to center spacing and tensioning gear, and lubricate well.
Unparallel of front and back shaft.
Improper installation of front and back shaft. 
Adjust installation, keep their depth of parallelism within 1/300.
