DIN.AL Flexible Couplings
The couplings lamellar DIN.AL. series "GEL" are usually used for coupling tachogenerators, encoders, contactors, motors, measuring instruments and all those applications where it is necessary to transmit a rotary motion with constant velocity in the four quadrants absolute torsional rigidity even when the coupling of trees does not appear perfectly aligned. Designed in compliance with the directives DIN 740 joints, especially for their construction, can absorb angular misalignment, axial and radial stresses on the trees without causing connected. For design details and materials used can be used within a temperature range from -30°C + 200°C.
The realization of our joints glued series "GEL" is made with quality materials. For bodies and the hubs are using a non-magnetic alloy treatment with galvanic corrosion. The ring junction, very important part of the joint because they must ensure both the transmission of torque that the elasticity of the system are made from a special bronze alloy. The union of the rings on the hubs and the body is guaranteed by special rivets. The grains for locking joints on the trees are made of stainless steel E-42 to ensure that no part of the joint itself can be attacked by corrosion.
The extreme compactness of the joints for easy installation even if performed in critical positions. The locking hubs on the shafts of the machines to be connected is normally done with two grain steel DIN 916 seats to 90° on each hub in the version marked by the letters G, can also be combined with a version tab and set screws DIN 916 UNI 6604-69: version marked by the letters CG. In the series GEL 500 S lock the hubs to the trees is entrusted to a special patented self-locking system. The hub bores are made with ISO tolerance H7. You should perform, for a correct assembly, processing of trees to be connected in ISO tolerance j6. To make the most of the elastic joints must be checked before mounting, alignment of the shafts of the machines to be connected in order to eliminate possible errors and radial angle. After installation check that there are abnormal pressures on the rings junction due to an error Cutting too high. The maximum errors angular, radial and axial are shown in the table of technical data. It is essential to keep in mind that these values are not used simultaneously.
The joints of the series and UNIMATIC UNIQUADRA are made of forged steel. The two hubs are anchored to the plate pack, real zzato harmonic steel with high strength bolts. Its simple structure and compact construction make it a viable alternative to traditional joints in torsional rigidity.
Series - UNIMATIC and UNIQUADRA
The joints of the series and UNIMATIC UNIQUADRA are made of forged steel. The two hubs are anchored to the plate pack, real ployed spring steel with high strength bolts. Its simple structure and compact construction make it a viable alternative to traditional joints in torsional rigidity. Virtually maintenance-free lubrication and allow a substantial reduction in operating costs and downtime.
The torque is transmitted evenly without transmitting vibration, the complete absence of backlash can come to an absolute precision. Dynamically balanced due to their type of construction joints can be supplied on request in the following versions:
- Processing of the hole of the ship's design.
- Preparation of the hub bore for the insertion of clamping.
- Hub available with taper bushes Series standards.
- Coupled with torque limiter. In collaboration with MWM Srl Milan.
All our joints are supplied with epoxy paint treatment. A request may be made other surface treatments.
Series - Multimatic-multiquadric
Keeping almost intact the technical characteristics of the series-UNIMATIC UNIQUADRA Multimatic-multiquadric series allows the user to correct misalignments additional. The creation of a multi-reed allows the inclusion of this particular joint in special applications.
Series - SPECIALMATIC
To better meet the changing needs of design, the series SPECIALMATIC, it is proposed to intervene where the scope of the programs require significant distances. This series allows you to provide, on request, spacers and extensions up to six meters in length. The joints of the series are available with SPECIALMATIC balance and personalized treatments.
