The utility model relates to a rack and pinion transmission closed loop detection mechanism, including encoder, shaft coupling, ring flange and gear shaft, said encoder is vertical to be passed the ring flange middle part and links to each other with the shaft coupling, and the vertical gear shaft that is connected with of shaft coupling lower extreme, gear shaft lower extreme are hugged closely and be connected with the gear, it has the spring groove to open between said gear shaft and the gear, and the circumference spring is installed to this spring inslot, gear shaft and gear between still open the locating hole of useful locating pin location. The utility model discloses external one the bidentate wheel spring of taking automatic compensation tooth clearance function crack structure that disappears, then be connected with absolute encoder with the shaft coupling, this structure is small and exquisite, the precision for a long time reliably just greatly reduced the lathe cost, stroke cost advantage long more is obvious more.
