APPRATUS FOR AUTOMATICALLY FEEDING LUBRICATION OIL IN UNIVERSAL JOINT

摘要

The present invention relates to a lubricating oil supply apparatus of a universal joint, which is able to: automatically supply lubricating oil to the inside of a cross kit by being easily mounted on the cross kit of the universal joint; recycle the lubricating oil; and easily check the residual quantity of the supplied lubricating oil with the naked eye. The lubricating oil supply apparatus of a universal joint includes the cross kit of a cross (+) shape which freely rotates at a predetermined angle by being inserted between two yokes. The lubricating oil supply apparatus of a universal joint comprises: a housing of a cylindrical shape which is combined to be able to be attached to and detached from the outer surface of the cross kit by including a connection unit of having an inlet connected with a lubricating oil path inside the cross kit and being combined with the outer surface of the cross kit and a storage chamber of being connected with the inlet of the connection unit and storing lubricating oil; a pressure plate which is installed to be able to slide in the storage chamber of the housing and pressurizes the lubricating oil in the storage chamber toward the inlet; and an elastic member which applies elasticity to the pressure plate toward the inlet of the housing.
