GREWIS Co. offers the largest assortment of hot - processed disc springs in Europa.
- Grewis Co. is producing disc springs from input material of thickness 2 mm - 35 mm and of diameter 40 mm - 700 mm.
- Toleration of disc springs adheres to standart ČSN 026063 and DIN 2093 (PDF; 320 kB)
- Disc springs with atypical dimensions can be produced according to the requirement of the customer as well as apart from both above stated norm.
- Disc springs are defined especially for big load with minimal deflection
Disc springs features
- Special features of Disc Springs (hereinafter DS)
- Great limiting force under low space necessity.
- Better utilization of the space towards another spring types in dependency with demand of limiting force achievement.
- Designation of spring possible loading forces by means of chosen way of linking into sets.
- The axial medial load with guiding pivot application, or with application of guiding cylinder.
- High stability under persistent and variable pressure as well.
- The heat treatment (hardening and tempering) in electric ovens prominently diminishes the risk of material decarburization.
- The springs side area and hole area are conical and they are supplied with the shot peening surface. According to the customer´s requirement may be also the zinc surface coating. Consecutively follows the protect coating.
Way of load and life expectation
- The static load - the DS are systematically stressed with permanent, constant stress without occurrence of break.
- The dynamic force the loading force is applied at BW within the given force interval.
- The variable load the DS are stressed with permanent or variable force according to the requirement applied.
DS utilization in set
- Single unit
- Sets with uniform seating (units laid one on the another)
- Sets with opposed seating (units laid one against another)
- Seats with combined seating (uniformly laid unids seated one against another)
Disc springs utilization:
- Metallurgy - mining and production engineering
- Power industry - pendant kettles for electric power stations
- Agriculture - cultivator sets,fertilizers and crushing machines
- Industrial processing - production of machines and of sets for tool, s fixing, safety valves, fittings, turbines
- Hydraulic engineering - spring brakes of motor vehicles
- General engineering - delimitation of compresion machine sets and devices
