CJ Series Hubs, Cast Iron, A And B Style Metric Bores
Flexible couplings are designed for linking two rotating shafts which are not properly aligned, for transmitting rotational power (torque) from one shaft to another. Flexible couplings comprise two hubs and a spider, with each hub being attached to a shaft while the spider flexes between the hubs for accommodating the misalignment between shafts. Shaft misalignments are radial, parallel or angular, and cause complications while transferring rotational power from one shaft to the other, in the form of loads, vibrations, stresses and other forces which change as per the type of misalignment.
Lovejoy coupling hubs are ideal for internal gas combustion engine and electrical motor applications. These Lovejoy CJ coupling hubs feature a curved jaw profile that helps in concentrating torque to the central region of the spider's limbs, thereby improving the efficiency of the elastomeric material. The three piece design of Lovejoy CJ coupling hubs makes them compatible with both radially and axially misaligned spiders.
These Lovejoy CJ coupling hubs are made of cast iron to ensure high compression strength and resisting corrosion on exposed surfaces. These Lovejoy CJ coupling hubs do not require any lubrication and prevent metal to metal contact for reduced friction. Lovejoy CJ coupling hubs, when assembled to form CJ Series couplings, deliver torque ranging from 67 to 247800 inch-lb.

SS Type Hubs With Rough Stock Bore
Lovejoy SS type jaw coupling hubs are designed for power transmission and accommodating shaft misalignment for gearboxes, electric pumps, motors, blowers and compressors. They transfer shocks and misalignments to the central part of the coupling assembly for wear minimisation on the shaft assembly. These hubs have no metal to metal contact to eliminate the need for maintenance and provide resistance to dirt, sand, oil, moisture and grease. They are made of stainless steel for fail safe operation even upon elastomer failure. Variants are available in bore diameters of 1/4 & 5/8 inches on Raptor Supplies.

Jaw Coupling Hubs

Jaw couplings are a type of flexible couplings designed to link two rotating shafts that are not properly aligned for transferring the rotational power or torque from one shaft to another. The jaw couplings are suitable for diverse industrial applications due to their versatile & robust construction and good speed capability, chemical resistance & dampening capability. Jaw couplings are easy to install, as they consist of only two jaw coupling hubs and a spider. These jaw coupling hubs are attached to the shafts and the spider flexes between the hubs for accommodating the misalignment & shocks. Shaft misalignments are mostly radial, parallel or angular and cause complications to transferring rotational power from one shaft to the other in the form of loads, vibrations, stresses and other forces, which change as per the type of misalignment.
The jaw coupling hubs are popular due to their fail-safe design that ensures interlocking of the coupling & continued operation (up to a certain extent) even after the elastomeric spider fails, wears out or gets loosened. Unlike gear, grid or chain couplings, jaw coupling hubs are also maintenance-free as they do not require periodic application of grease or additional maintenance (provided that the spider remains intact). These jaw coupling hubs are made of cast iron, powder metal, sintered iron, sintered carbon steel, steel or zinc alloy to ensure high compression strength and durability. They are also offered in aluminium or stainless steel construction for lightweight and resistance to corrosion in food & pharmaceutical environments.
Lovejoy jaw coupling hubs are available in two broad types: straight jaw coupling hubs and curved jaw coupling hubs. Straight jaw hubs are made from a diverse range of materials and feature straight jaws for adjusting to various styles of spiders. They are used with open centre spiders, snap wrap spiders with retainer rings; closed centre spiders having Nitrile Butadiene (Buna N), urethane, Hytrel or bronze construction. Curved jaw coupling hubs (Lovejoy CJ Series) on the other hand, feature a curved jaw profile that concentrates the torque to the central region of the spider's limbs, thereby improving the efficiency of the elastomer material and reduces rotational backlash. They are mostly used with open centre elastomeric spiders to accommodate shafts having little separation.
Choose from a wide range of these jaw coupling hubs, available in both unbored and bored variants on Raptor Supplies. The bored variants are offered in bore sizes ranging from 1/8 to 4 inches.

Uses

Jaw coupling hubs are ideal for linking two shafts when used in conjunction with elastomeric inserts or spiders to form couplings. These jaw coupling hubs are used in a wide range of motion control (servo) applications, such as conveyors, escalators, motor vehicles, forestry, agricultural & mining equipment in robotics, automobile, aeronautics and space industries.

Features

Jaw coupling hubs in conjunction with spiders form jaw couplings and are used to transmit rotational power from one shaft to another.
They are equipped with an optional bore or a hole at the centre of the hub for ease of mounting on the shafts. Users can identify the bore size or bore diameter of a hub for selecting a correct sized jaw coupling hub for their use.
These hub bores may also have keyway slots to fit a key and prevent slipping of the hub on the rotating shaft. Keyway size indicates the height and width of the keyway slot to fit in the right sized key.
The jaw coupling hubs have an effective length through the bore to help them slide-fit on the shaft & the optional key.
These hubs handle the torque from the driving shaft and pass it onto a driven shaft while handling shocks, vibrations & angular misalignment. Torque refers to the applied force causing rotational motion. In imperial units, torque is expressed as inch-pounds (in.-lbs.) whereas, in metrics, it is expressed as Newton-meters (Nm).
They have diverse types of designs, constructions and bore tolerances for handling a wide range of rotational speeds (maximum speed).
These jaw coupling hubs feature fail-safe mechanism for continuing the operation up to a certain time, in case the shock-absorbing spider inserts wear down or fail to interlock.
They provide highly reliable service without any metal to metal contact to prevent regular wear & tear.
These jaw coupling hubs are resistant to oil, dirt, moisture & grease for ensuring long term operation.

Working Mechanism

A jaw coupling is made of three parts: two metallic hubs (jaw coupling hub) and an elastomer insert / element or spider. The spider has many lobes to fit the jaws of hubs alternatively for a tight press fit. Once the machinery starts running & the driving shaft starts rotating, the hub jaws attached to the driving shaft push towards the driven hub jaws and thereby towards the stationary shaft.
The jaws being locked together leads to torque transfer and rotation of the stationary shaft. The jaw coupling torque is then transmitted through the elastomer / spider lobes compressed between the hub jaws. These elastomeric spider legs act as coupling absorbers and help in cushioning the force between the driving & driven jaws. They absorb the vibration and shock from torque transfer and consequently protect the surrounding components from getting damaged.

Standards and Approvals

Lovejoy jaw coupling hubs meet the ANSI/AGMA 9002-B04 or 9112-A04 and ISO 9001:2008 industry standards for superior performance of the hubs.
