Detailed description of the invention
As shown in Figures 1 to 9, the present embodiment provides a kind of engineering machinery pin shaft connection structure, and bearing pin 1 uses heat treatment
Technique and (or) electroplating technology process to increase the bulk strength of bearing pin 1.One end of bearing pin 1 is fixing connects fixing baffle ring 11, from
One end of bearing pin 1 arises from the shaft core position of bearing pin 1 and offers central blind hole 12, and in central blind hole 12, assembly connection has lubricator cup
13, the side surface of bearing pin 1 offers three lubrication holes 14 connected with central blind hole 12, from lubricator cup 13 charging-up lubricant oil
Fat, lubricant grease enters into the outer surface of bearing pin 1 through central blind hole 12, lubrication hole 14, lubricating pin shaft 1 and the first connector 6,
Two connector the 7, the 3rd connector 8 and the contact surfaces of the 4th connector 9, to improve the service life of pin shaft connection structure.Bearing pin 1
The other end offer screwed hole 15 in the shaft core position of bearing pin 1, bolt 3, through movable baffle ring 2 assembly connection screwed hole 15, makes pin
Axle 1 is not susceptible to axial float, and will not damage the fixed structures such as bolt 3, and reliability is higher.In order to prevent colliding with of bolt 3
