How to attach by using rubber bushes
• Rubber bushes can be used only in the case of one direction operation.
• Material of rubber bushes : Black natural rubber
• Hardness : IRHD 75
• Because rubber may deteriorate by ambient environment, be carefully.
(High temperatures more than 50 ?, Direct rays of the sun and Dispersion of oil etc.)
• In the case when a deterioration of rubber bush is found at daily check, change it for new one.
However rubber bushes are consumables, they do not become objects of the compensation.
How to attach with spring washers
• The spring washers that our supply are equivalent to DIN 2093 standardized.
• Use the volts that have more than 10.9 for JIS strength class.
• Attach the spring washers without gap in the part of attachment ( "A" in fig.13 ).
If there is gap in the part of attachment, it is afraid that the torque arm is damaged.
• Check spring washers that are smashed. If the spring washers are attached with tightening of nuts such that they are
smashed, they are afraid that spring washers have no function for shock absorbing ,and that BUDDYBOX and the
machine of the customer are suffered too much force. In the case of using double nuts, be careful to tighten them
without smashing of spring washers.
• For the wear reduction of the spring washers, apply any lubricant such as grease to faces of contacting each spring
washers.
• Make always the bolts looseness prevention such as using adhesive for looseness or U-nuts.
• In the case that gap is arise on the part of attachment by initial sag of spring washers, adjust to turn gap to zero-gap
with secondary tightening of the nuts.
Then be careful not to smash the spring washers.
