Lead screw mounting structure and mounting method thereof

Abstract

The invention discloses a lead screw mounting structure and a mounting method thereof. The lead screw mounting structure comprises a lead screw and a bearing. The upper portion of the lead screw is inserted into and fixed to the center of the bearing, a load is arranged on the lower portion of the lead screw, the external diameter of the part, inserted into the center of the bearing, of the upper portion of the lead screw is smaller than the external diameter of the lower portion of the lead screw, and one or more stepped grooves are formed in the part, inserted into the center of the bearing, of the upper portion of the lead screw. The lead screw mounting structure further comprises a split type lead screw shoulder ring and a bearing fixing part, the split type lead screw shoulder ring is arranged on the upper portion, inserted into the center of the bearing, of the lead screw in a sleeving mode, and the bearing fixing part is mounted outside the split type lead screw shoulder ring. According to the lead screw mounting structure and the mounting method thereof, a lead screw retaining ring is divided into two half symmetrical parts, a plurality of stepped grooves can be selected according to the size of the load, the reliability is greatly improved compared with the mode that the lead screw is fixed through a nut, the lead screw shoulder ring is in a split type design, the external diameters of materials needed by lead screws of the same specification are small, the lead screw can be machined conveniently, materials are saved, and using is more flexible.

Description

Technical field [0001] The invention mainly relates to a screw mounting structure and a mounting method thereof. Background technique [0002] Screw drive is an ideal product that converts rotary motion into linear motion, or converts linear motion into rotary motion. At present, in order to reduce the complexity of screw processing, reduce the outer diameter of the screw material, and save material, usually the screw is fixed to the bearing by processing the thread on the screw, and the screw is fastened with two nuts. On the bearing, this structure has unreliability, poor safety and small load during use. When the screw is rotating at high speed, the nut will slowly loosen during long-term use, and the nut will rotate. Once the above situation occurs, the wire The rod will fall down under the drive of the load, and accelerate the wear of the thread, which will eventually fall off directly, causing serious accidents and great losses. The above structure is more obvious under t...
