Embodiment Construction

[0035] Fig. 1 is an exploded view of the ball screw reflux device of the present invention; wherein the nut 1 of the ball rod fits on the screw 2, and the relative movement is generated by rolling the balls 3 therebetween, and the inner diameter of the nut 1 has a ball groove 1e for matching The screw 2 makes the ball 23 roll in the return channel.

[0036] The ball screw backflow device of the present invention utilizes at least one backflow device 4, including two backflow passages 4a assembled in the radial hole 1c in the center of the nut 1. After the backflow device 4 is inserted into the radial hole 1c, the backflow passage 4a is aligned with the return flow hole 1a of the nut 1 , and the threaded groove 4b is aligned with the threaded groove 1b of the nut 1 , so that a bolt (not shown) can pass therethrough to fix the return device 4 and the nut 1 . The end plugs 5 with a single return channel are inserted on both ends of the nut 1. The two end plugs 5 cooperate with a ...

Abstract

The invention relates to a ball bearing reflux device, which utilizes at least one reflux device with two reflux channels mounted at the center of a screw cap, wherein two ends of the screw cap are respectively arranged with a plug with one-way reflux channel to divide a ball groove of the screw cap into at least two independent ball circulate rings, therefore, the cap can process multiple ball circulations without increasing length and the pre-pressure of cap can be adjusted by bias pre-press method.

Description

technical field [0001] The invention relates to a ball screw return device. Background technique [0002] Most traditional ball screws use a return tube or return cap as the return device of the ball screw. Using these traditional return devices can make the ball screw designed with double nuts or offsets. The preload increases the rigidity of the ball screw. The end deflector type return device is a relatively new design (such as USP5492036), which uses end plugs arranged at both ends of the nut of the ball screw, and cooperates with the return flow hole ( return hole), so that the balls in the ball screw can circulate between the ball groove of the nut, the end plug and the return flow hole. However, in the above-mentioned end-plug type return device, since all the balls move in the same ball circulation loop, it is not suitable to design the preload in an offset manner to improve the rigidity of the ball screw.
