Abstract

The invention discloses a connecting mechanism which comprises a driving shaft, a driving part sleeved on the driving shaft as well as a clamping key positioned between the driving shaft and the driving part; a first thread part and a second thread part are formed on the driving shaft; the connecting mechanism further comprises an adjusting part screwed on the first thread part and a locking piece screwed on the second thread part; the driving shaft is axially provided with a mounting groove positioned between the first thread part and the second thread part; the driving part is provided witha clamping groove; the clamping key is wedged and is partially clamped in the mounting groove of the driving shaft and partially clamped in the clamping groove of the driving part; and two ends of the clamping key are respectively supported against the adjusting part and the locking part. The connecting mechanism has the advantage of long service life.

Description

technical field [0001] The invention relates to a connection mechanism, in particular to a key connection mechanism. Background technique [0002] In the key connection mechanism, the key is a mechanical part used to connect the transmission shaft and the components on the transmission shaft, such as gears, couplings, etc., and fix the above-mentioned components in the circumferential direction to achieve torque transmission. [0003] A key connection mechanism includes a transmission shaft, a gear and a flat key. The flat key is roughly in the shape of a rectangular strip. The transmission shaft is provided with a rectangular groove matching the flat key, and the flat key is embedded in the rectangular groove and partially protrudes from the outer surface of the transmission shaft. The center of the gear is provided with a connection hole, and the arm of the hole is provided with an engaging groove matched with the flat key. When the gear is sheathed on the transmission ...
