Product Description
Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.
Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc
Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.
How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

How to use the coupling safely
The coupling is an intermediate connecting part of each motion mechanism, which directly impacts the regular operation of each motion mechanism. Therefore, attention must be paid to:
1. The coupling is not allowed to have more than the specified axis deflection and radial displacement so as not to affect its transmission performance.
2. The bolts of the LINS coupling shall not be loose or damaged.
3. Gear coupling and cross slide coupling shall be lubricated regularly, and lubricating grease shall be added every 2-3 months to avoid severe wear of gear teeth and serious consequences.
4. The tooth width contact length of gear coupling shall not be less than 70%; Its axial displacement shall not be more significant than 5mm
5. The coupling is not allowed to have cracks. If there are cracks, it needs to be replaced (they can be knocked with a small hammer and judged according to the sound).
6. The keys of LINS coupling shall be closely matched and shall not be loosened.
7. The tooth thickness of the gear coupling is worn. When the lifting mechanism exceeds 15% of the original tooth thickness, the operating mechanism exceeds 25%, and the broken tooth is also scrapped.
8. If the elastic ring of the pin coupling and the sealing ring of the gear coupling is damaged or aged, they should be replaced in time.

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.

A coupling can interchange and replacement of lovejoy coupling is a device used to connect 2 shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join 2 pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost.
Coupling is a jaw type coupling that works for a variety of light duty to heavy duty motors used in electric power transmission.
This is 1 of our safest types of products. The reason being that these couplings work even when the elastomer fails and there is no metal to metal contact.
