Abstract

A grease applicator is described which applies grease in the form of rings on assembly parts, resulting in controlled uniform distribution of a grease layer. In Figs. 1 and 2, grease applicator 10 consists of a body 11 containing cavities 12 and 13 which are connected through orifice 14. Cavity 13 contains a closely fitted plug 15 which contains a bore 16 into which assembly parts 17 are inserted. Plug 15 also contains annulus 18 which is open to bore 16 and is connected to cavity 13 through eight symmetrically placed access holes 20. Cavity 13 is filled with grease by grease-filled syringe 21 which is fitted into cavity 12. In operation, part 17 is inserted into bore 16 against O-ring 122 which shields the end of part 17 during the application of grease.

Grease Applicator

A grease applicator is described which applies grease in the form of rings on assembly parts, resulting in controlled uniform distribution of a grease layer. In Figs. 1 and 2, grease applicator 10 consists of a body 11 containing cavities 12 and 13 which are connected through orifice 14. Cavity 13 contains a closely fitted plug 15 which contains a bore 16 into which assembly parts 17 are inserted. Plug 15 also contains annulus 18 which is open to bore 16 and is connected to cavity 13 through eight symmetrically placed access holes 20. Cavity 13 is filled with grease by grease-filled syringe 21 which is fitted into cavity
12. In operation, part 17 is inserted into bore 16 against O-ring 122 which shields the end of part 17 during the application of grease. An air pressure pulse is applied to syringe 21, forcing a controlled amount of grease from annulus 18 onto part 17 in the form of an evenly distributed ring. O-rings 22 and 23 prevent grease from escaping the pressurized chamber. The grease applicator can be used with manual insertion and removal of parts, but the device is readily adaptable to a robot-controlled part insertion and removal. In the above configuration the amount of grease released is controlled by the duration and force of the air pressure pulse. Another configuration for the control of the amount of grease is illustrated in Fig. 3. Cylinder 24 contains grease-filled cavity 25, spring-loaded plunger 26 and air inlet 27. Plunger...
