Abstract

The utility model belongs to the technical field of motor auxiliary equipment, and in particular relates to a motor belt adjusting device. An adjusting device which drives a sliding bottom plate and translates thereon is arranged on one side of a fixed bottom plate, and comprises a threaded shaft connected with one end of the fixing bottom plate through a screw, wherein the middle part of the threaded shaft is connected with a locking nut through the screw; a connecting seat movably matched with the threaded shaft is arranged on the sliding bottom plate; one end of the threaded shaft is rotatably connected with the connecting seat; and a fixing hole and a fixing seat are molded on the fixing bottom plate and the sliding bottom plate respectively. The motor belt adjusting device has the advantages as follows: the fixing bottom plate is matched with the sliding bottom plate in a sliding manner, and the threaded shaft is connected with the bottom plate through the screw, so that the adjustment accuracy is high due to that the only requirement is to screw in or screw out of the threaded shaft during the adjusting process. After the adjustment is finished, the locking nut is tightened to be closely attached to the fixing bottom plate. The motor belt adjusting device has the advantages of good stability, easiness and simplicity in operation and low manufacturing cost, and is suitable for the majority of belt-driven motor products.
