Golf trollies' sheared pins problem
solved
A leading manufacturer of luxury golf trolleys, turned to an alternative supplier to solve an engineering design problem when axle pins holding the wheels in place were shearing.
Stewart Golf, a leading manufacturer of luxury golf trolleys, turned to Spirol Industries to solve an engineering design problem when axle pins holding the wheels in place were shearing The pins had been supplied through a distributor and when Spirol Industries was asked to examine them, the form of the coil was not precise and the colour appeared slightly different than expected

Compression limiters made for moulding in
Compression limiters for moulded in applications are used to preserve a threaded joint's integrity when fastening plastics-to-plastics assemblies, or plastics-to-metal assemblies.
Plastics threaded joint integrity maintained
Solid knurled compression limiters preserve the integrity of a plastics threaded joint when a metal bolt is inserted, preventing creep, loosening and eventual failure of the joint.
Stewart Golf was using the CLDP pin as a stop pin to prevent the movement of a plastic wheel centre, with the rubber attached to outside rim, from moving about on the bottom axle of the trolley.
It was in this application that premature shearing was being experienced.
The pin was shear and hardness tested and conformed to all expected levels.
However, Spirol found that two issues were found to be affecting the performance of the pin.
Firstly, the plastic wheel centre had a curved hole which the pin lay flat against.
Secondly, the hole in the shaft which the pin was being pushed into was counter bored.
This decreased the amount of material around the length of the pin and therefore the amount of radial tension the pin could achieve was reduced.
Spirol advised Stewart Golf to omit both of these counter bores in their next prototype.
The result has been a further 20KN strength on the pin and it now performs as expected.
Stewart Golf is now dealing directly with Spirol Industries and the advantages for them are clear: full the engineering support and application advice, a fully traceable product and a range of standard range off the shelf pins.
