Backlash free bellows flexible couplings are available with either a set screw or clamp fixing as standard from Ondrives Ltd of England.
There are two types available to purchase - choose from either a stainless or bronze bellows, hubs are either aluminium or stainless steel. They have a high torsional stiffness and response with complete absorption of eccentricity, angularity and end play by spring action of bellows configuration. Uniform rotational speed, even under misalignment, is acheivable with these couplings. They also have identical clockwise and anti-clockwise rotational characteristics as well as being maintenance free and oil and chemically resistant.
e-cad drawings are available from our website, www.ondrives.com to ensure you are happy with the products before purchasing from our secure online ordering system.

DELTEX - shaft couplings are marked by small dimensions and
weights, as well as having low mass moment of inertia at high torque
transmission. The running properties and durability expectations
of the couplings have been obtained by precise surface finishing of all sides of the coupling. The shock loads produced by irregularly working power machines will be optimally dampened and absorbed. DELTEX – shaft couplings transfer the torque formsafe, are rotation elastic and safe against break through. DELTEX - couplings adjust axial, radial and angle changes. All steel parts are corrosion protected.
Function:
DELTEX - shaft couplings consist of two facing hubs, made of steel or aluminium, between which an elastic spider is mounted.
The elastic and form constant torque is transferred by this spider.
The elastic spiders made of special polyurethane are available in
various hardnesses according to application as well with rounded
teeth sides (DELTEX-S) or with straight teeth sides for torque transfer
free of play (DELTEX-GSS).

Lovejoy's S-Flex coupling design is simple, ensuring ease of assembly and reliable performance. No special tools are needed for installation or removal. S–Flex couplings can be used in a wide variety of applications.
Its design is comprised of three parts. Two flanges with internal teeth engage an elastomeric flexible sleeve with external teeth. Each flange is attached to the respective shaft of the driver and driven and torque is transmitted across the flanges through the sleeve. Misalignment and torsional shock loads are absorbed by shear deflection in the sleeve.
In all designs, pre-molded teeth along the diameter of the sleeve engage with teeth of the coupling flanges. No clamps or screws are needed to connect the flanges with the flexible sleeve which securely lock together under torque for smooth transmission of power. All three sleeve materials are highly elastic which permits the S–Flex coupling to protect connected equipment from harmful shock loading, vibration, and shaft misalignment.
The S–Flex coupling from Lovejoy offers combinations of flanges and
sleeves which can be assembled to suit your specific application. Thirteen
sizes are available with torque capabilities that range from 60 in-lb to
72,480 in-lb.

Lovejoy offers a variety of designs and models in its gear coupling family. From standard, off-the-shelf stock to new, high speed, special designs, Lovejoy can satisfy your gear coupling needs. The original Continuous Sleeve, or “C” coupling, offers a lightweight, compact, and simple design without compromising torque carrying capacity. The Flanged Sleeve, or “F” coupling, is available in exposed or shrouded bolt styles in which the number of bolts, size of bolts, and bolt circle are identical with industry standards. The nylon sleeve gear couplings, Nyflex and Mite, are compact, lightweight couplings that use a nylon sleeve and two sintered iron hubs. Lubrication is not required with the nylon sleeve. Lovejoy also has an All Metal Labyrinth Seal coupling and an Alloy Steel coupling. The All Metal Labyrinth Seal coupling is a flanged sleeve style, but uses no elastomeric seals. The Alloy Steel coupling is made from AISI 4140 steel.

Extensive developments of CNC technology has meant ever more dynamic and complex related driving elements are now required, and it is for this reason that Rino Industries Ltd of Chesterfield have a range of metal bellows couplings to accommodate this.
They have considerably proven their worth when used at highly controlled dynamic drives. They are used wherever two rotating opposite shafts are to be connected frictionally and backlash free. The most important characteristic of these types of couplings is that they can be mounted very easily and fixing of the hubs is affected only by simply tightening the fastening screws. This is why the couplings can also be easily mounted to inaccessible locations.
Contrary to the AK series, the AKD and AKN couplings can be supplied with adjusting spring grooves, and clamping is designed in a way as to guarantee that the torque transfer without adjusting spring grooves is absolutely backlash free, even with high speeds. Any misalignment of the shafts is therefore compensated and acoustic noise of the motor or the drive is reduced by acoustic damping.
They are highly suitable for use at numerically controlled machinery and equipment, packaging machinery and transporting equipment. Both types of couplings are within a torque range of 18-500Nm and within a shaft diameter range of 10-60mm. The couplings are also easily made to customer’s specifications.
