Abstract
A coupling device for equipment implements is described, which coupling device does not impair the lubricity of bearing sections when the equipment is in service, does not cause seizure during rotation of bearings, does not need frequent feeding of grease to the bearing sections from outside, and provides good noise absorbability. The coupling device has such a structure that a metal based contact material 7 capable of storing a lubricating oil and/or lubricant is interposed between an implement bushing 1 made from steel and implement pin 4 of an implement for construction equipment.
Claims25
An implement coupling device which is composed of an implement bushing made from steel and an implement pin which are for use in an implement for construction equipment,
- wherein a metal based contact material having a structure capable of storing a lubricating oil and/or lubricant is interposed in a gap defined by the implement bushing and the implement pin.
An implement coupling device which is composed of an implement bushing made from steel and an implement pin which are for use in an implement for construction equipment,
- wherein a metal based contact material having a structure capable of storing a lubricating oil and/or lubricant is integral with the outer circumference of the implement pin.
