Novel ball screw

Abstract

The invention discloses a novel ball screw, and belongs to the field of ball screws. The novel ball screw comprises a screw body, a ball rail is arranged on the surface of the screw body, a screw nut is slidably mounted on the surface of the screw body, mounting grooves are equidistantly formed in the inner wall of the screw nut, balls are fixedly mounted on the inner walls of the mounting grooves, the balls are slidably connected with the ball rail, through holes are formed in the inner walls of the mounting grooves, partition plates are fixedly mounted on the inner walls of the through holes, and lantern rings are fixedly mounted on the inner walls of the through holes. Through arrangement of first threaded holes, fastening bolts, first backing rings and other structures, connecting pieces can be fixedly connected; under the action of second fastening bolts, limiting holes and other structures, the long-time fastening effect of the fastening bolts is guaranteed; and through the arrangement of oil injection holes and the through holes, a certain amount of oil can be stored in the through holes, and connecting rods can be pulled to drive sealing plugs to be separated from the partition plates, so that the oil accurately drops to lubricate components such as the balls and the ball rail, and the problem of friction stagnation is solved.

Description

technical field [0001] The invention relates to the field of ball screws, more specifically, to a novel ball screw. Background technique [0002] Ball screw is an ideal device for converting rotary motion into linear motion or converting linear motion into rotary motion. Due to its small frictional resistance, ball screw is widely used in various industrial equipment and precision instruments. [0003] However, most ball screws also have certain defects. The connection stability between the screw nut and the connecting piece is not good, and the long-term fastening performance of the fastening bolt is weak, and the long-term frictional rotation of the ball and the ball track, There will be a sense of friction and stagnation, and there is no good lubrication mechanism. Contents of the invention [0004] Aiming at the problems existing in the prior art, the object of the present invention is to provide a new type of ball screw, which can be fixedly connected to the connecti...
