The Principle and Structure Of Film Spring of Agricultural Clutch

The film spring in the agricultural clutch is a common spring device, which is used to provide pressure and elasticity between the clutch pressure plate and the flywheel to ensure good contact of the friction plates and reliable power transmission. The following is a detailed explanation of the principle and structure of the agricultural clutch film spring:

Principle:

The principle of the film spring is based on elastic deformation, which has restoring force and elastic rebound ability. When the film spring is compressed or deformed by an external force, it will store energy, and release the energy when the external force disappears or decreases, returning to its original state. This elastic characteristic allows the film spring to provide the pressure and elasticity to maintain tight contact between the clutch pressure plate and the flywheel.

Structure:

Agricultural clutch disc springs typically consist of a series of interconnected metal plates forming a ring or arc. These metal sheets are usually elastic and flexible so as to elastically deform when subjected to external forces. The structure of the film spring can have different designs, but common structures include the following.

Monolithic film spring: Consisting of a sheet of metal bent into an arc, similar to a bent leaf spring.

Multi-sheet film spring: composed of multiple metal sheets superimposed and connected to each other to form a ring or stacked structure. Each metal sheet has a certain thickness and width, so that the whole spring device has greater elasticity and bearing capacity.

In agricultural clutches, the disc spring is usually located between the clutch pressure plate and the release mechanism. They apply force through the release mechanism, which transmits pressure to the clutch pressure plate, maintaining tight contact between the clutch pressure plate and the flywheel. The design and material selection of the film spring needs to take into account the required compression and spring characteristics to meet the requirements of a specific clutch system.

In general, the film spring in the agricultural clutch uses the principle of elastic deformation to provide pressure and elasticity between the clutch pressure plate and the flywheel by storing and releasing energy, so as to achieve reliable power transmission and operation control.
