Difference between single-support and double-support transmission shaft frame
Thread Content
What is the difference between single-frame and double-frame mixing equipment? What are the advantages and disadvantages? Could some expert please help answer this!
1. In terms of price, double-pivot racks are more expensive than single-pivot ones; however, they are also more stable. 2. For racks of the same size, double-pivot racks offer better earthquake resistance compared to single-pivot racks. Taking a cantilever shaft as an example, in a double-support frame, the diameter of the cantilever shaft is equal to the diameter between the two bearings, with no difference. There is a difference in the shaft diameter at each single pivot point. The ratio of the critical speed of the mixing shaft in a double-pivot frame to its critical speed is relatively small. 3. Specifically, the choice between a single pivot and a double pivot is based on a comprehensive consideration of factors such as stability and cost-effectiveness
To be more specific: 1. The motor or reducer has a support point that, upon calculation, can bear the load of the agitator shaft. 2. A bottom bearing is provided, which can also serve as a support pivot. 3. The shaft seal unit is equipped with a bearing that can function as a pivot. If one of the above conditions is met, a single-pivot frame can be selected.
A single-support frame is suitable for applications with low power transmission and low axial loads, while a double-support frame is the opposite.
