The reducer box and the lid are generally cast from HT-15-33 or HT20-40 gray cast iron. Can also be welded steel plate, there are still castings box, while the lid is welded. Some reducer manufacturers can not reach the target technology, the casting, welding out of the reducer box, the lid can not meet the user's requirements. Resulting in reducer cooling performance, short service life, many problems and so on. Therefore, the order reducer, it is recommended to find like Shanghai Lian Heng Precision Machinery Co., Ltd. This specialized production reducer manufacturers.
Reducer design gear box and cover, the requirements to meet the strength, steel under the premise, but also consider its compact, easy casting, light weight and the use of such requirements. Because the reducer box and the lid is the most stress-reducing components in the structure.
What is the difference between casting and welding? Casting gearbox good rigidity, easy to get beautiful appearance, suitable for mass production, especially with gray cast iron gear box is also easy to cut, but the cast gear box heavier. Welding deceleration gear box light, save material, short production cycle. But demanding welding techniques are only suitable for single-piece production. Reducer box can be made of straight walls and curved walls and other shapes. The former structure is simple, but the weight is larger, while the latter structure is more complex, but lighter weight.
