Description

TECHNICAL FIELD

[0001] The utility model relates to automatic oiling device technical field, specifically, a stroke adjustable gear automatic oiling device. BACKGROUND

[0002] In the working instrument that relies on gear to realize mechanical transmission, in order to reduce the wear generated in the working process, usually before assembling gear, it is necessary to smear lubricating grease to the gear meshing part.
