Technical field
The utility model is related to hydraulic cylinder technical field, especially a kind of dual lubricating arrangement of servo hydraulic cylinder.
Background technology
Hydraulic jack is that hydraulic energy is changed into mechanical energy, straight reciprocating motion is done or the hydraulic pressure of oscillating motion performs member
Part, its simple in construction, reliable operation, is realized with it during reciprocating motion, can remove deceleration device from, and without drive gap,
Stable movement, therefore be used widely in various mechanical hydraulic systems.Servo hydraulic cylinder requires low speed without creeping phenomenon,
Frictional resistance between piston rod and cylinder head, piston rod and cylinder body is very small.Lubricating system traditional at present utilizes transmission
Bronze powder guidance tape does support rubbing surface, but still can not meet the use requirement of servo hydraulic cylinder.
Utility model content
The technical problems to be solved in the utility model is：Overcome deficiency in the prior art there is provided one kind is simple in construction, watch
Take the dual lubricating arrangement of hydraulic cylinder.
The utility model solves the technical scheme that its technical problem used：A kind of servo hydraulic cylinder is filled with dual lubrication
Put, including cylinder body, cylinder head is installed in cylinder body one end, cylinder body and cylinder head are built-in with piston rod, piston rod outer surface include with cylinder head
On the first contact surface that wall is engaged and the second contact surface being engaged with inboard wall of cylinder block, the first contact surface and the second contact surface
Provided with lubricant coating；Oil pressure chamber and oil circuit are provided with the cylinder head, oil circuit one end is communicated with oil pressure chamber, the oil circuit other end and
Cylinder head inner chamber is connected.
Further, described lubricant coating includes hard chromium layers of the plating in piston rod surface, is coated with outside hard chromium layers poly-
Tetrafluoroethene layer.
The beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design, easy to operate, oil pressure chamber
Interior to be filled with lubricating oil, lubricating oil enters the gap between cylinder head and piston rod by oil circuit, improves the profit of cylinder head and piston rod
Slip energy；In the first contact surface of piston rod outer wall and the second contact surface spraying lubricant coating, hard chromium layers improve piston rod outer wall
