ABSTRACT

Box is an important component of reducer. It is the base of transmission parts and

should have enough strength and hardness. Welding treatment of equipment base is the

trend of equipment manufacturing industry. The original heavy and complicated casng

structure is changed into welding structure, which has the characteriscs of simple structure,

convenient manufacture, convenient maintenance and structural transformaon.

This design takes the casng gearbox box as an example to explore the welding

transformaon of the welding reducer. According to the drawings of the casng one-stage

deployable cylindrical gear reducer, it completes the manufacturing process of the welding

one-stage deployable cylindrical gear reducer. Welding instead of casng is a kind of process

method to replace casng blank with welding components, which can e$ecvely avoid

defects such as porosity, sand inclusion and shrinkage porosity of casng blank. Especially for

the box parts with complex structure, uneven wall thickness and poor casng process, this

process provides a be&er choice for the producon organizaon in terms of blank quality and

producon cycle.

KeyWord: Reducer box, welded box, box welding process
