Reverse clutch, also known as overrunning clutch, is a mechanical component that can transmit torque in one direction, allowing movement in one direction and preventing movement in another direction under specific conditions. The main function of the reverse clutch is to prevent components from reversing or reversing in mechanical equipment when there is no power source, especially in material conveying equipment such as belt conveyors and bucket elevators, which play a crucial role. The types of reverse clutch include belt reverse, roller reverse, and irregular block reverse, each with its unique working principle and application scenarios.
The belt type backstop mainly consists of three parts: a limiter, a brake band, and a stopper. In normal working condition, the brake belt is stored in the limiter. When the drum reverses, the brake belt is brought between the nylon conveyor belt and the rubber coated drum, and the reverse rotation of the transmission drum and the strong wear-resistant rubber belt is stopped by frictional force. This type of backstop has a simple structure and is suitable for low-power belt conveyors, but its disadvantage is that when stopping, it needs to be reversed for a section first. The larger the diameter of the drum, the longer the reversal distance will be. Therefore, high-power and high-capacity mobile conveyors are not suitable for use.
Roller backstop is a roller overrunning clutch consisting of an inner ring, an outer ring, rollers, and springs. During normal operation, the inner ring rotates counterclockwise and the rollers do not work. When the inner ring rotates clockwise, the rollers move towards the small end of the wedge-shaped space under the action of the spring force. Due to the friction between the rollers and the inner and outer rings, the inner ring cannot move and acts as a reverse stop. When the outer ring is not fixed, it can be used as a speed limiting overrunning clutch.
The irregular block backstop is a special form of irregular block clutch applied to backstop, consisting of a backstop body and a backstop arm. When the rotational speed of the inner ring is greater than that of the outer ring, the irregular block hardly generates frictional force; When the speed of the outer ring is greater than that of the inner ring, the irregular block gradually squeezes the inner and outer rings under the action of friction, making the speed of the inner and outer rings close and achieving the function of surpassing the clutch. When the outer ring remains stationary and the inner ring reverses, the irregular block takes effect, achieving a reverse stop effect.
The design and application of reverse clutch cover a wide range of industrial fields, including packaging machinery, printing machinery, food machinery, medical machinery, textile machinery, various machine tools and reducers, etc. They can withstand axial and radial loads, have one-way self-locking function, and are easy to reverse release. They are suitable for various mechanical transmissions within the limit speed and nominal torque range. The correct selection and use of reverse clutch are of great significance for ensuring the safety of mechanical equipment and improving production efficiency
