PRODUCTS:

Trapezoidal screw jacks.

This line includes three sizes and its peculiarity is that some components made of a polymer with high mechanical characteristics.

Having a structure quite similar to full metal, Aleph screw jacks have the same load handling functions and maintain the same IRREVERSIBILITY features. The particular molding system of the gears and the peculiarity of polyarylamide adopted permit to operate even without lubrication.


Aleph
screw jacks can work singularly or in groups connected by means of joints, shafts and bevel gearboxes. It ‘also possible a direct motorization with flange.

In addition to the trapezoidal screw jack, Unimec also produces jacks for ball spindles. For the realization of its products, Unimec uses materials that allow high performance, thereby creating stainless steel screw jacks and a polymer jacks (Aleph).

Base models:

TP

For threaded spindles with axial shift
The input shaft is converted into rotary motion of the threaded spindle axial rectilinear displacement by means of the worm wheel.
The THREADED ROD MUST HAVE A CONTRAST POINT

TPR-1

TPR

Rotating threaded spindle with nut
By the rotational movement of the input shaft through the worm wheel, integral with the threaded rod, you have the rotation of the rod itself.
With external support nut (lead nut), integral with the load, there is movement.
The NUT MUST ALWAYS HAVE A ROTATIONAL CONTRAST

Jacks with trapezoidal screw in polymer – ALEPH.

This line includes three sizes and its peculiarity is that some components made of a polymer with high mechanical characteristics.
Having a structure quite similar to full metal, Aleph screw jacks have the same load handling functions and maintain the same IRREVERSIBILITY features. The particular molding system of the gears and the peculiarity of polyarylamide adopted permit to operate even without lubrication.
Aleph screw jacks can work singularly or in groups connected by means of joints, shafts and bevel gearboxes. It ‘also possible a direct motorization with flange.

Jacks rod with recirculating ball.

By experience in the construction of trapezoidal screw jacks are born jacks for ball spindles, proposed in the K series. The K series screw jacks are suitable for high services and very quick and precise positioning.

As compared to trapezoidal screw jacks, the K series presents a transmission REVERSIBILITY: it is therefore advisable to provide for brakes, blockings or contrast torques in order to prevent reverse motion. It can be driven by different motors: ac motors, dc and brushless.
The special hollow shaft mounting allows to assemble any Spindle Ball on the market, making the K series really UNIVERSAL.

Complete machining of the external surfaces and the special care in the assembly to make installation easier and allow the application of supports, flanges, pins and any other components that the project may require.

The use of special sealing systems allow the operation of the internal gear in a bath of lubricant, so to ensure a long lasting life.

Bevel gearboxes.

The range consists of nine sizes, tenths of mounting schemes, a range of serial ratios up to 1/12 and a design capacity of no equal, make UNIMEC a reliable partner in the field of motion transmission.

 

The cubic shape of bevel gearboxes is practical and allows a universal installation on each machine. The bevel gearboxes are also very versatile with regard to the shafts choice and the possibility of direct connection to any type of motor, IEC or brushless. High efficiency and low noise are the logical consequence of bevel gears spiral teeth Gleason®; the use of this kind of geometry and suitable thermal treatments place the bevel gearboxes steel UNIMEC at the top of this mechanical sector.

UNIMEC produces a large variety of bevel gearboxes, suitable for all needs of the project, including:
keyed hollow shaft, shrink disc or splined, with male shaft and / or with reinforced hubs and more.

Stainless steel screw jacks and bevel gearboxes.

The new market requirements and hygiene standards of the food industry and applications in oxidizing environments, require an increasing use of stainless materials.

Always UNIMEC was able to provide its customers with its stainless steel products. However the realization of such components required long processing times.

Regarding the products and sizes of more turnover, UNIMEC is now able to propose a complete series: the X series. The advantages of this choice are several: first a reduction of the delivery times as the components are available from stock, second the working process by moulding components allow to obtain quite interesting costs.

Speed modulation gearboxes.

The operation principle of UNIMEC’S speed modulation gearboxes is the same as the planetary gearboxes, the only difference being the external ring gear, is not connected to the body, but is contrasted by an adjustment worm screw.

Rotating this device, and as a consequence rotating the planetary system too, it is possible to modify the transmission output revolution speed.

Machines made of various working stations, with conveyor belts and feeding lines (typical of the paper, packaging and press sectors, etc.) find their ideal solution in the speed modulation gears, in order to synchronize the various delivery phases.

Speed modulation gearboxes can also be used as non-stop speed modulators. It is therefore possible, in case for example of coiling lines, to modify the speed of one or more stations in order to obtain constant pulls.

Other typical applications for speed modulation gearboxes are the press machines, the sheet working machines, the paper and packaging machines, where the control for waste reduction and for the machines setting requires high handling precisions.
3 versions, 5 models and 85 construction forms, mean a wide range of application for a designer. In addition to standard models, UNIMEC is able to provide special custom designed speed modulation gearboxes suited to the requirements of specific machines.

Lamellar and R + W couplings

To complete its range of production, UNIMEC is capable of providing high torsional rigidity lamellar couplings or those produced by R + W.

 

The lamellar couplings offer an absolute torsional rigidity in both rotation directions, and a transmission capacity of high torques. Others plus are the resistance to corrosion, vibration absorption, the use in all conditions of temperature and a practically unlimited period without any kind of maintenance.

 

The R + W couplings instead offer greater dynamism and versatility and can be provided  with the transmission extensions.

Lubricants and accessories kit
