The parallel shaft reducer has long been the preferred choice for high-torque applications. Also known as an in-line gear reducer, this type of Falk gear reducer has input and output shafts that are parallel to each other and usually features a helical or double-worm gear design. The efficiency of the parallel shaft reducer makes it one of the most flexible, compact and power-dense designs in industrial power transmission equipment, which is why it’s so well suited for applications requiring a lot of torque.
Common Applications for Parallel Shaft Reducers
The parallel shaft gearbox reducer is most commonly used for conveyor systems – especially within the mining industry – where low speeds and heavy torque are desirable. The parallel Falk gear reducer is also found in bucket elevators, crushers and even some mixers. In addition to being used for transporting metals, the parallel shaft reducer also plays a role within the lumber, textile and rubber industries.
Benefits of a Parallel Shaft Reducer
While the parallel shaft reducer once held exclusive dominion over high-torque applications, it now faces heavy competition from the concentric drive, whose design advancements have enabled it to handle higher torques at a lower cost than the parallel shaft drive. However, the parallel shaft gearbox reducer still has some advantages over the concentric drive – namely that it allows for in-place repair, without the need to drain lubrication or remove other elements. Its life can sometimes be prolonged merely by flipping the gear train so it operates on a different flank.
When selecting a Falk gear reducer for any application, it’s important to consider not only cost and capabilities but also usability features and ease of repair or replacement. Because of its versatility, the parallel shaft reducer is still a competitive drive for many applications.
