Cardan joints & shafts applications
Cardan shaft applications
The combination of experience, in process industries for steel and paper mills, in delivering power from stationary engines, electric motors and turbines, and meeting the demands of the rail industry.
Cardan joints & shafts
1.Small series – for low speed applications with torque capacity up to 2500 Nm
2.Medium series – for general engineering, torque capacity from 2,000 to 45,000 Nm
3.Heavy duty series – from 40,000 to 580,000 Nm. Shafts with greater capacities on demand.
4.Service parts
All levels of repair are available – re-balance existing shaft, replace UJ, complete overhaul, and new replacement.
Today, Timothy holding provides total support, parts and service for all types of shafts.
Drive shaft for rolling mills
Drive shaft/cardan shaft/propeller shaft
A drive shaft, driveshaft, driving shaft, propeller shaft (prop shaft), or Cardan shaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them.
Drive shafts are carriers of torque: they are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, whilst avoiding too much additional weight as that would in turn increase their inertia.
To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or moreuniversal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint.
Mechanical engineering cardan shaft
Mechanical engineering cardan shaft
A shaft with a universal joint at its end to accommodate a varying shaft angle.
Inmotor vehicles, a Cardan shaft is used to connect the motor and transmission(at an angle of up to 5°), the transmission and transfer case (at an angle ofup to 5°), and the transmission or transfer case and the rear-axle drive (at anangle of up to 15°), as well as in steering gear or winch drive.
ACardan shaft consists of a propeller shaft with two (less frequently one)Cardans. If the propeller shaft is connecting mechanisms between which theangle and distance vary (for example, the transmission and rear-axle drive of amotor vehicle), overhang balance is provided in the form of a slip splinedjoint, which makes possible a change in the length of the shaft within setlimits. Depending on the angle between the propeller shafts in a Cardan shaft,rigid or flexible semi-Cardan joints, full Cardans of unequal angular velocity,or Cardans of equal angular velocity may be used. Full Cardans, which have twojaws, needle bearings, a spider, mounts for the spider journals, and atightening mechanism, are the most commonly used type. The efficiency of asingle Cardan is 0.985–0.99.
Drive shaft coupling / cardan shaft coupling
- http://www.timothyholding.com/
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. 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.
The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.

Universal Coupling Maintenance
Coupling Maintenance
Coupling maintenance is generally a simple matter, requiring a regularly scheduled inspection of each coupling. It consists of:
- Performing visual inspections, checking for signs of wear or fatigue, and cleaning couplings regularly.
- Checking and changing lubricant regularly if the coupling is lubricated. This maintenance is required annually for most couplings and more frequently for couplings in adverse environments or in demanding operating conditions.
- Documenting the maintenance performed on each coupling, along with the date.
Even with proper maintenance, however, couplings can fail. Underlying reasons for failure, other than maintenance, include:
- Improper installation
- Poor coupling selection
- Operation beyond design capabilities.
The only way to improve coupling life is to understand what caused the failure and to correct it prior to installing a new coupling. Some external signs that indicate potential coupling failure include:
- Abnormal noise, such as screeching, squealing or chattering
- Excessive vibration or wobble
- Failed seals indicated by lubricant leakage or contamination.
