How do I choose a Belleville washing machine?
How do I choose a Belleville washing machine?
You must prepare the joint properly (as with any connection), but the key is selecting the proper design and size of Belleville washer for the fasteners and conditions of your application. Selecting the right Belleville washer You have to deal with three parameters here: torque, diameter, and finish.
How many times can you use a Belleville washer?
Depending on the application, multiple Belleville washers can be used to create greater resistance against heavy loads. Rather than using a single Belleville washer, you can use two or three Belleville washers.
What material are Belleville washers made of?
DIN Belleville Disc Washers are made with 51CrV4 spring steel (AISI 6150) and finished with a phosphate and oil surface for general protection from corrosion.
Where is Belleville spring used?
Belleville springs are compact and are capable of large compressive forces but their deflections are limited. Examples of their use include gun recoil mechanisms, pipe flanges, small machine tools and applications where differential expansion could cause relaxation of a bolt (Fig. 15.30).
How do I choose a disk spring?
For static, or dynamic applications, select a disc spring that at 75% of its total available deflection offers the maximum force and/or deflection required. Between 75% deflected and the ‘flattened’ position, the actual force/stress characteristics become considerably greater than those calculated.
Do you torque Belleville washers?
b) When using Belleville spring washers, bolts should be tightened until a sudden increase in torque is felt. This indicates the Belleville spring is flattened and no torque wrench is required. discusses connecting Aluminum to Copper; however, Belleville springs can be used with all conductors and terminal lugs.
How are Belleville washers used?
Belleville washers are typically used in conditions of high current loading or cycling. They are used to absorb vibration and can maintain preload in bolted joints, indicating correct preload based on the gap between adjacent washers. They can also help with “bolt creep” or stress relaxation between a bolt and washer.
Can you stack spring washers?
Stacking. Multiple Belleville washers may be stacked to modify the spring constant (or spring rate) or the amount of deflection. Mixing and matching directions allow a specific spring constant and deflection capacity to be designed.
What are the applications of spiral spring?
Spiral spring is widely used in mechanisms, such as mechanical watch movements and clocks where the spiral spring is used for timekeeping.
Which way do arc washers face?
- The arc washer curved side should fit flush with the curve of the bar.
- Rounded side should be facing bolt head so that the opposite curved inside of washer fits the rounded metal frame perfectly.Hopefully this answers your question more clearly.
Why is it called a Belleville washer?
The Belleville spring is named after its founder, Julian F. Belleville, around the mid 19th century. They were designed to take on really heavy loads, with the steel that is used to make them. Belleville designed the washer to be a spring as well.
