Aluminum cam & grooved hose coupling, camlock coupling

1. Advantages of Keyed Shaft Coupling
-Overload conditions cause the grid element to shear, like a mechanical fuse
-Grid can be changed "in place," saving time
-Low maintenance
-Quick operation
-Allows for parallel / angular misalignment and permits end float
-Torsional flexibility
-Interchangeable part by part with Falk*
-Horizontal H covers, vertical V covers, and spacer styles
-High transmission efficiency and safe starting, transmission efficiency can reach to 99.47%
when torque is being transferred
-Vibration reduction can reach to 36% on average
-Grid coupling life is longer than other non-metal elastic part couplings.

2. Application of Keyed Shaft Coupling
A coupling is a device used to connect two shafts together at their ends for the purpose of
transmitting power.
The primary purpose of couplings is to join two pieces of rotating equipment while permitting
some degree of misalignment or end movement or both. We mainly make grid couplings.

4. Details of Keyed Shaft Coupling

 *Work Principle

 The steel tapered grid coupling is similar in nature to a steel gear coupling, except the connecting sleeve 

is replaced by a flexible chrome-vanadium alloy leaf spring grid. The steel hubs are cut with profiled slots, 

allowing the grid to engage circumferentially.

The grid "springs" deflect under torque, distributing the peak torque load over a large angle of rotation. 

The inherent property of torsional softness allows the coupling to absorb shock loads.

Light Load

The grid contacts near the outer edges of the hub teeth. A long span between the points of contact

remains free to flex under load.

Normal Load

As the load increases, the distance between the contact points on the hub teeth is shortened, 

but a free span still remains to cushion the load. 

Heavy Load

The coupling is flexible within its rated capacity. Under extreme overloads, the grid bears fully on 

the hub teeth and transmits full load directly.

 Light load, less contact.

 Heavy load, more contact.  

 Based on actual changeable work load, grid will deform in corresponding degree to fit shaft and 

 damp shock and vibration, protect the host device.

*Long service life

Tapered grids, made of high quality spring steel, undergo strictly heat treatment to perform its 

best strength and resilience. It greatly outlasts other non-metallic elastic element coupling. 

Allow for large installation misalignment. The coupling can work normally under the condition of 

co-existed parallel, angular and axial misalignment.

 *Professional design,various types

 Type G hydraulic grid coupling can provide various types of design for customer’s choice. 

There are 4 types available: basic type, split type, basic type with sensor, split type with sensor.

*High safety level

Temporary overloads can withstand 2 times the rated torque, which makes the device safe and reliable.

 *Low installation requirements

 Allow for large installation misalignment. The coupling can work normally 

 under the condition of co-existed parallel, angular and axial misalignment.

 *Low operating cost

No need for specialized periodic maintenance when under normal use, as long as fill sufficient amount of 

 grease during installation and replenish grease after long time working. As grease can reduce the 

 transmission noise.

 *Allowable Misalignment

 Maximum life and minimum maintenance for the coupling and connected machinery will result 

 If couplings are accurately aligned. Coupling life expectancy between initial alignment and 

 maximum operating limits is a function of load, speed and lubrication, so misalignment must be 

 within its maximum operating limits at installation and operation.
