Oldham coupling for use in fuel high pressure pump for fuel injection system of internal combustion engine, has disk with oil supply channel in form of holes and grooves, where grooves extend from surface to another surface of disk
Oldham coupling for use in fuel high pressure pump for fuel injection system of internal combustion engine, has disk with oil supply channel in form of holes and grooves, where grooves extend from surface to another surface of disk
The coupling has a claw hub connected with a shaft i.e. cam shaft, in a torque-proof manner, and a cross-type disk (4) inserted into the claw hub. The disk is coupled with a claw device of another shaft i.e. engine drive shaft, in a torque-transmitting manner. The disk has a lubricating oil supply channel (5) in the form of holes (6) and grooves, where the grooves extend from a front surface to another front surface of the disk. The holes and/or grooves are arranged at equal distance to each other in an area of claws (11) of the disk, where the claws are connected with claws of the claw hub.
