Disc spring
Disc spring (for bearing) (Material: Spring steel)
KN

Disc springs, also known as disc springs (disc springs), can achieve the required load value through different stacking combinations, greatly reducing the compression space required by the coil spring, which is very suitable for small installation spaces and high loads. Heavy machinery or equipment, which is one of the products that are currently used in a large number of mechanical components.

Product Features
1. It has the ability to obtain a large load in a small space and a small amount of compression
2. Through the change of the combination, the spring characteristics can be changed
3. Wide range of applications, multiple functions and high efficiency
4. Long service life
5. Strong buffering ability

Guide way
When the disc springs are overlapped, they need to be guided to prevent lateral sliding.
The guiding method includes inner diameter guiding and outer diameter guiding, and the guiding mode can be arbitrarily selected according to the design conditions.
In general, more inner diameter guides are used, and the stability is good.

Scope of application
1. Power transmission components, such as clutches, brake systems, disk drive shafts, etc.
2. Components of electrical system transmission switchgear
3. Cutting center machine, drilling machine, control valve, ball valve, etc.
4. Studs, screw elastic washers such as pipeline conveying systems, pipeline supports and punches
5. Components of heavy machinery such as lifts, cranes, and stackers
6. Components of automated machinery, such as knitting machines, printing machines, etc.
7. Large electric motors, gasoline turbines, diesel engines, pumps and other components
8. Punch die, bearing preload, oil seal
9. Components of seats for aircraft, locomotives, bicycles, etc.
