Description

Technical Field

[0001] This utility model relates to the field of speed reducer manufacturing technology, and in particular to a press-fitting fixture for producing bimetallic worm gears for speed reducers. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine, matching speeds and transmitting torque between the prime mover and the driven machine or actuator. It has extremely wide applications in modern machinery. The worm gear in a speed reducer is generally made of either all-copper alloy or all-steel. However, all-steel worm gears have poor meshing performance, while all-copper alloy worm gears have disadvantages such as high manufacturing and maintenance costs.

[0003] To address this, our company has designed a bimetallic worm gear for a speed reducer. The inner ring metal casting is made of copper-based material, and the outer ring metal casting is made of steel-based material. The inner and outer ring metal castings are snapped together and rotated to lock, and are fixedly connected using radially arranged fasteners.

[0004] In the existing technology, there is a lack of press-fitting tooling to meet the requirements for the production and assembly of the bimetallic worm gear of the aforementioned reducer. It is not possible to quickly press the inner ring metal casting into the outer ring metal casting and to make the radial fastening holes of the two interlock and connect through rotation. Summary of the Invention
