Khodiyar Spring Industries, located in Ahmedabad, is one of the best Belleville washer manufacturers in India. We make high-quality spring products and offer competitive pricing. For identification of the best industrial springs consider the specifications of the product and ensure it must comply with the DIN standards. Product quality matters when buying machine parts.
Belleville washer is an industrial spring that’s used to obtain different deflection and load results.
A Belleville washer, also known as conical-disc spring, Belleville spring, conical spring washer, or cupped spring washer, can produce high loads in a tiny area and has a high spring rate. These washers can be stacked together in the same orientation, alternating orientation, or used as a single spring.
Belleville washers are made from the best quality stainless steel and are also available in other materials. Their configuration varies and can be classified into different groups based on the thickness of the material, the inner and outer diameter of these springs.
Based on the thickness of the material Belleville washer are classified into 3 groups -
Less than 1.25 mm thick.
The washer thickness between 1.25 mm to 6 mm.
Thickness over 6mm to 14 mm.
Belleville spring washers exert uniform and constant pressure. Belleville washers do well in situations of thermal expansion/contraction, compression set, or in conditions where the wear of parts causes tension losses.
The stacking of Belleville washers can be done in many ways and each stacking option gives different results-
Single washer.
Parallel combination.
Series combination.
The mix of series-parallel combination.
These different combinations give different results. A single Belleville washer has a specific load for any given deflection.
Two washers stacked in a parallel combination will yield double the load in the same deflection. Three washers will yield triple the load, and four washers will yield four times load for the same deflection.
In a series combination, the results will differ from those obtained by a parallel combination.
Two washers in series will yield double the deflection for the same load as a single one used. Three washers will yield triple deflection, and four washers will show four times the deflection for the same amount of load.
Various combinations of series and parallel stacking will give a variety of combined results for the stack in the form of load vs deflection.
For increased load and same deflection, stack the washers in a parallel combination.
For increased deflection and same load, stack the washers in a series combination.
The stacking of Belleville washers can be done in many ways and each stacking option gives different results-
It easily supports large loads.
It has a long service life under a dynamic load
These washers are used to provide diminishing and maintain high tension in bolted applications.
Belleville washers solve the issues of vibration, thermal expansion, bolt creep problems, relaxation.
As mentioned above, the Belleville washers can be used in various combinations when you plan to stack multiple discs to obtain the desired results. To understand the correct fit Belleville washer for your needs, get our consultation.
