Abstract: A circulating element for ball screw includes a first surface defining a circulating passage that extends from one lateral side of the first surface to the other lateral side of the first surface and has a coupling mouth located on each of the two opposite ends thereof, and a second surface defining a coupling groove between the two coupling mouths of the circulating passage and two guide blocks respectively protruding out of the coupling mouths of the circulating passage. Thus, the circulating element has the advantages of low processing cost, ease of installation, high alignment accuracy, and excellent running smoothness.

Abstract: A transmission mechanism with monitoring function includes a shaft, a moving part, a circulating device, a plurality of rollers and a monitoring module. The shaft has a roller groove. The moving part is movably disposed on the shaft. The moving part has a roller slot corresponding to the roller groove. The roller slot has an effective thread section and an ineffective thread section. The effective thread section and the roller groove together form a load path. The circulating device is disposed on the moving part. The circulating device has a return channel communicated with the load path. The return channel and the load path together form a circulating path. The plurality of rollers are disposed in the circulating path. The monitoring module includes a gathering body and a sensor. The sensor is for detecting a metal content of the lubricant in the gathering channel.

Abstract: A ball screw with maintenance device includes a screw shaft including a helical rolling groove; a nut having an outer circumferential surface in which at least two mounting holes is formed; two recirculation elements, which are mounted to the nut and each having a through hole having an open end set in a spacing distance from the rolling groove; a fixing cover mounted to the outer circumferential surface of the nut and includes a concentration trough formed therein. The through hole has an end communicating with the concentration trough. The concentration trough is connectable to a suction tube or an oil/grease supply tube. The suction tube can remove contamination from the interior of the nut through the through hole, and the part that has been cleaned up with the suction tube can be replenished with fresh oil/grease with the oil/great supply tube to achieve complete maintenance of the ball screw.
