Get more torque without sacrificing
space
Right-angle gearheads offer machine designers a compact and lightweight solution for gaining extra torque from servomotors without sacrificing space.
ZF Industrial's new WT range of right-angle gearheads offer machine designers a compact and lightweight solution for gaining extra torque from servomotors without sacrificing space The single-piece housing offers maximum rigidity and high-efficiency operation in applications where drive systems turn through 90deg

Hysteresis brakes and clutches replace servos
The ability of ZF's unique hysteresis brakes and clutches to perform precise tension control operations on larger systems has been enhanced with the introduction of new high power brakes.
Gearboxes speed machining centre assembly
The key to fast deliveries on AB Marwin machining centres is ZF's two speed gearboxes, which are an essential component in this approach.
The compact design of ZF's WT series gearboxes benefits from a single-piece, cast aluminium housing, enabling integration into systems where space and weight are a consideration.
A cast housing creates a more rigid structure, which allows greater torque output from a smaller unit and contributes to operational efficiency levels of 96%.
The compact design and high torque output of the WT gearheads is further improved by the use of novel hypoid teeth which permit high ratios in a bevel gear system.

ZF appoints Home Counties distributor
ZF Industrial's unique range of hysteresis tension control products is now being supplied through DJ Automation, over an area centred on Bedfordshire.
Hysteresis clutch and brake range is available
The appointment of Newton Tesla (Electric Drives) as ZF Industrial's distributor for the north of England ensures that the ZF hysteresis range is available from specialist suppliers in the UK.
Parameter optimised for greater strength, the hypoid gears keep inertia output torque to a minimum, ensuring maximum torque transmission from the gearhead (up to 1,440Nm) and levels of backlash that can be as low as 2.0 arc-minutes.
A major feature of the WT design is that torque transmission from the units is wear and clearance-free.
This is the result of the effectiveness of the force locking shaft/hub connection between the WT gearhead and its attached servomotor.
In addition, torsional rigidity is excellent as a result of transverse loads being handled effectively by the gearheads' high quality taper-roller bearings.
The precision in manufacture, component selection and assembly which ZF exercises in the production of the WT gearheads ensures a long nominal service life, typically in excess of 30,000 hours.
The provision of lifetime grease lubrication means that operation is essentially maintenance-free during this life span.
This is true even in adverse environments where an enclosed design, with IP64 ingress protection, guarantees reliable performance.
Maximum convenience and installation cost savings are provided to the machine builder by the ability of the WT gearheads to be integrated easily on any machine.
The flexible design gives the user the choice of a number of solid and hollow shaft output options.
The task of integration is also simplified by the gearheads ability to be mounted in any orientation, this the result of using grease lubrication rather than oil.
WT series gearheads are offered with a choice of 8 integer ratios (in the range 3:1 to 15:1), and comprehensively cover the mechanical power and torque ranges required in most industrial motion control applications.
The many design and operational advantages provided by the gearheads mean that they are ideally suited to precision motion tasks in packaging, materials handling, semiconductor manufacturing, food processing, paper and pulp manufacturing, metal forming, medical diagnostics, printing, textiles, robotics, optical positioning, and many more.
The WT gearheads are backed-up by the resources of one of the most respected manufacturers of driveline technology in the world.
