Abstract
Official abstract text for this publication.
A screw nut on which a pulley is mounted is capable of promoting reductions in the size and weight thereof. The screw nut includes: an outer ring; and a nut rotatably assembled to the outer ring via a first rolling element. The nut includes: a nut body having a screw groove in an inner surface thereof; and a recirculation component provided at an end portion of the nut body in an axial direction, the recirculation component having a turn-around path for recirculating a second rolling element rolling along a screw groove. A pulley to be mounted on the nut is fitted on an outer surface of the nut body, and is brought into contact with an end surface of the nut in the axial direction. The pulley is mounted on the end surface of the nut with a fastening member.
First claim
Opening claim text (preview).
The invention claimed is: 1. A screw nut comprising: an outer ring; and a nut rotatably assembled to the outer ring via a first rolling element, the nut including a nut body having a screw groove in an inner surface thereof, a recirculation component provided at an end portion of the nut body in an axial direction, the recirculation component having a turn-around path for recirculating a second rolling element rolling along the screw groove, and a metal component mounted on an end surface of the nut body in the axial direction, the metal component including a metal lid member covering the recirculation component housed in a recess in the end surface of the nut body in the axial direction and being in contact with an end surface of the nut body in the axial direction, wherein an outer diameter surface of the nut body is configured to receive a pulley mounted thereon, the pulley being brought into contact with an end surface of the metal component and being mounted on the end surface of the metal component with a fastening member screwed in the nut body. 2. The screw nut according to claim 1 , wherein an outside diameter of the lid member is smaller than an outside diameter of the nut body.
