GH4090 disc spring
Classification:
- Product Description
-
The disc spring is a conical disc and can be used alone or in series or parallel. Undertake dynamic load along the upper or lower edge. When compressed, it deforms until it flattens. It can be used as a live load in the form of stored energy, automatically converted to the additional compression load required for sealing when necessary, supplementing the continuous requirements of gaskets and packing, maintaining the rated load, and reducing unnecessary downtime and leakage losses.
Din disc springs follow din2092 design standards and din2093 manufacturing standards. Can provide 3 ≤de ≤ 1000mm,t ≤ 80mm DIN standard size products and special size and material products. Please consult us immediately! Advantages Disc springs have a history of more than 60 years.
Compared with other springs, it has a series of unparalleled advantages
Elasticity Design System for Nickel-based Superalloys and Intermetallics
Small space, small displacement
According to the size relationship, the characteristic curve can be designed as a straight line, an asymptote or a regression line.
Single disc spring or combination spring can be added according to the characteristic requirements
If the size is right, it can maintain a long service life even under dynamic load
Under normal load, as long as it does not exceed 75% of the total displacement and stress limit, there will be no fatigue phenomenon and good rebound performance can be maintained
When properly combined, greater damping can be obtained to absorb vibration and release energy
Single disc springs can be combined to reduce inventory
Due to the ring shape, the force transmission is absolutely concentric
Inner and outer diameter tolerance: outer diameter fitting tolerance H12, inner diameter fitting tolerance H12, concentricity: 2 × it11 when de ≤ 50mm, 2 × it12 when de>50mm. Take the disc spring with outer diameter de = 40mm, inner diameter Di = 20.4mm, and thickness t = 1.5 as an example. The mark is as follows: disc spring 40x 20.4x 1.5 Note 1. When multiple pieces are used in parallel, the load change caused by friction is shown in the following figure: 2. Multiple pieces in series.
The best arrangement is to use a small number of microcontrollers, and the larger the diameter of the series, the better.
Due to friction, the displacement instability increases with the increase of the number of plates in series.
If the total length exceeds 2, use a flat washer.
Friction is mainly caused by the following four factors
As long as there is displacement in the internal friction, there is inevitably friction
Friction between disc spring and end face
Friction between disc spring and shaft center
When connected in parallel, the friction between the disc springs is 1. The hardness of the disc spring in contact with the shaft and the end face is 55HRC (at least 8 μm deep). 2 When used under dynamic load, high-pressure grease containing MoS2 must be used.
