China OEM Customized Giclz Type Crane Gear Coupling, Drum Gear Shaft Coupling, Gear Coupling for Crane gear coupling
Product Description
Hot Selling Stainlenss Steel Drum Gear Coupling Flexible Giclz Type Shaft Axle Couplings
Description:
A gear coupling is a mechanical device for transmitting torque between 2 shafts that are not collinear. It consists of a flexible joint fixed to each shaft. The 2 joints are connected by a third shaft, called the spindle.
Each joint consists of a 1:1 gear ratio internal/external gear pair. The tooth flanks and outer diameter of the external gear are crowned to allow for angular displacement between the 2 gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are called gears because of the relatively large size of the teeth.
Gear couplings and universal joints are used in similar applications. Gear couplings have higher torque densities than universal joints designed to fit a given space while universal joints induce lower vibrations. The limit on torque density in universal joints is due to the limited cross sections of the cross and yoke. The gear teeth in a gear coupling have high backlash to allow for angular misalignment. The excess backlash can contribute to vibration.
Gear couplings are generally limited to angular misalignments, i.e., the angle of the spindle relative to the axes of the connected shafts, of 4-5°. Universal joints are capable of higher misalignments.

Accommodating Misalignment and Reducing Vibrations in Flexible Gear Couplings
Flexible gear couplings use an elastomeric flexible element, often made of high-quality rubber, to connect the two gear hubs. This design allows the coupling to accommodate misalignment between the connected shafts and reduce vibrations during operation.
1. Misalignment Accommodation: The flexible nature of the elastomeric element allows it to bend and flex as the shafts move out of alignment. Flexible gear couplings can accommodate three main types of misalignment:
- Angular Misalignment: Occurs when the shafts are not parallel and are at an angle to each other.
- Parallel Misalignment: Occurs when the shafts are not in a straight line but are parallel to each other.
- Axial Misalignment: Occurs when the shafts are displaced along their axis.
The ability to handle these types of misalignment is crucial in various industrial applications where machinery may experience movement, thermal expansion, or other dynamic forces.
2. Vibration Reduction: The elastomeric material in the flexible gear coupling acts as a damping mechanism. It absorbs and dissipates vibrations and shocks generated during operation. This damping effect helps in reducing noise levels and protects the connected equipment from damage caused by excessive vibrations.
Overall, the combination of misalignment accommodation and vibration reduction in flexible gear couplings contributes to improved system reliability, reduced maintenance requirements, and extended machinery life.

The flexible gear teeth act as shock absorbers, dampening these vibrations and preventing them from propagating throughout the system. This helps reduce noise, wear, and stress on the machinery components, contributing to smoother and quieter operation.
- Load Distribution: The flexibility of the gear teeth allows the coupling to distribute the transmitted load evenly across the entire tooth surface. This even load distribution reduces wear and fatigue on the gear teeth, increasing the coupling’s overall lifespan and reliability.
- Overload Protection: In case of sudden shock loads or overloads, the flexible gear teeth can absorb part of the impact, protecting the connected equipment from damage. This feature is especially important in applications with variable loads or potential shock events.
- Torsional Flexibility: The gear teeth’s flexibility enables the coupling to handle torsional movements, ensuring that torque is smoothly transferred between the shafts even if they are not perfectly aligned. This feature helps maintain constant velocity transmission, critical in precision systems.
Overall, the flexibility of gear teeth in flexible gear couplings allows these couplings to adapt to changing conditions, provide protection against unexpected forces, and improve the performance and reliability of mechanical power transmission systems.

How Does a Gear Coupling Protect Connected Equipment from Shock Loads and Vibrations?
Gear couplings are designed to provide excellent protection to connected equipment from shock loads and vibrations, making them ideal for use in demanding and heavy-duty applications. The design and features of gear couplings that contribute to this protection include:
- Flexible and Rigid Elements: Gear couplings consist of two hubs with external gears that mesh together. Between these two hubs, there is a center sleeve with internal gear teeth. The center sleeve acts as a flexible element, while the outer hubs act as rigid elements. This combination allows the gear coupling to transmit torque while absorbing and dampening shock loads and vibrations.
- Misalignment Compensation: Gear couplings can accommodate angular, parallel, and axial misalignment between shafts. When the connected equipment experiences misalignment due to dynamic forces or shock loads, the gear coupling can flex and adjust to these changes, preventing excessive stress on the shafts and equipment.
- High Torsional Stiffness: Gear couplings offer high torsional stiffness, meaning they have minimal angular deflection under load. This stiffness helps maintain precise alignment and reduces the likelihood of damage to the connected equipment caused by misalignment-induced vibrations.
- Load Distribution: The toothed gear design of gear couplings ensures a large surface area of contact between the gears. This spreads the torque evenly across the gear teeth, resulting in a uniform distribution of load and reducing the concentration of stress on specific areas.
- Damping Characteristics: The flexible center sleeve in the gear coupling acts as a damping element that absorbs and dissipates vibrations, further protecting the connected equipment from harmful oscillations.
- High-Speed Balancing: Gear couplings are precisely balanced during manufacturing to minimize vibrations and ensure smooth operation even at high speeds. Proper balancing helps prevent resonances and reduces the impact of shock loads on the connected equipment.
By effectively absorbing and dampening shock loads and vibrations, gear couplings extend the life of the connected equipment and surrounding components, reduce maintenance requirements, and contribute to a more reliable and efficient mechanical system. However, it is essential to select the appropriate size and type of gear coupling based on the specific application and operating conditions to ensure optimal protection and performance.
