Abstract
Disclosed herein is a leadscrew ball recirculation block with oil storing means wherein an cavity in the ball recirculation block which being not effectively used for circulating balls is utilized for storing lubrication oil. An oil exuding hole is provided to communicate with the oil stored cavity and a turning passage for balls so as to lubricate the moving balls. In order to prevent the lubrication oil remained at a standstill in a certain region in the cavity by its own gravity from failing to lubricate the balls, there is provided an oil containing element with a plurality of oil absorbing and distribution branches to lubricate the balls just passing by the turning passage. Furthermore, the ball recirculation block is formed of two pieces of plastic members bonded by supersonic wave bonding technique so as to achieve reduction of manufacturing cost and ensure perfect oil sealing effect of the ball recirculation block. With the result of such a construction, the usable lifetime of the ball recirculation block is prolonged and repeated replenishing of new oil is evaded. (FIG.,)
