Spindle nuts with plastic trapezoidal thread

Construction:machined; 1 turn - right-handed, splitted on one side2 flanges for bellows connector in dry runsthread constructed according to DIN 103quality: 7e according to DIN 103

Materials:

Thread:

The load values apply to an ambient temperature of 20°C and an operating period of 100% in dry runs.When lubricating with oil or grease or when reducing the operating period, the load can considerably increase,especially in the upper screw speed range. In such cases please ask for the permissible axial loads at ourapplication development department. The values ascertained have been determined with spindles made fromthe following material:Spindle material: Ck15 (1.1141);hardness:150HB; surface roughness: Rz 6,3µm; quality: 7e according to DIN 103

Applications of stress:

The spindle nuts are available in three types of material.An appropriate material has to be chosen depending onthe load exerted on the spindle nut.

The spindle nuts have 6 volume boreholes of a diameter of6 mm for screws M5.We achieve a regular power distribution by means of areinforcement with a 2mm thick stainless sheet steel flange.The diameters and lengths of the nut must show a clearanceof 0.1mm towards the connecting parts when installed, inorder to ensure a maximum load without hindering a thermalexpansion.

Trapezoidal spindle nut for presses ZX-100K

Objective:

Spindle drive for a corpus press of the wood-processing industry

Two trapezoidal spindle nuts are inserted outside the jector bar of the press.They run on trapezoidal spindles made from the material 9SnPb36 and transferthe total compression power to the blank, that is to be pressed.

Cyclic traction / compression stressTraction: up to 224,8 lbf / spindle nutCompression: up to 4496,18 lbf / spindle nutScrew speed: 233 rpmRunning time: 80 %

A metric thread M59x1,5 outside the plastic spindle nut is important for its attachment.By means of this thread the nut is screwed into a steel casing and sticked together with it.

Freedom from maintenance, only single lubrication on installation.Lifespan of 6 years, reduction of costs.

A spindle nut made from ZEDEX 100K with an acme thread TR40x12 and a length of 3,346 inis employed here.

Since 1995 the spindle nut has been employed and since then no problems have arisen whilst in use.

Replacement of expensive bronze nuts.Maintenance-free operation with one initial lubrication.

Threaded nuts for positioning table

Threaded nuts for positioning table ZX-100K

Fa = 67,44 Ibfn = 790 rpm

The threaded nut shows a process way of 0,984 in on its pole.The threaded pole is ground and cured (60HRC) and is driven by a stepper motor.

By means of a thin-wall zone, where the nut does not show a thread, the nut can easily bepre-stressed, so that an accurate positioning of 0,000039 in can be achieved.

Dry run free from stick-slip, high-precision positioning.High damping as the drive is effected by a stepper motor.

A threaded nut M8x0,5 made from ZEDEX 100K is now employed, which has considerably beenshortened compared to the previously employed PTFE-nut.

In contrast to a ball circulation spindle, the combination trapezium threaded spindle / ZX-100K-nutshows an outstanding damping. Highest accuracy can be achieved. Thanks to the pre-stressing of thenut, the downtime can be reduced to 0. The material PTFE has been replaced with ZX-100K here.

The threaded nuts are adapted to the positioning table.They must be extremely easy-processing in order to obtain an efficiency as big as possible.Counter-rotating material here is a spindle made from cut St50.

Thread M6x1,25Length = 0,393 inStroke = 0,984 inFa = +/- 67,44 lbfn = 300 rpmRunning time = 10 %Lubricated with LM47.

The coefficient of friction must be below 0,03 in order to achieve a total efficiency of more than 75 %.

A nut without an intentional pitch fault, which is not pre-stressed and lubricated, enables the easy run.

An expensive brass nut is replaced with a nut made from ZX-100K.Higher efficiency, longer lifespan and price reduction are achieved.

Karl Deinhammer - Ott-

Freedom from maintenanceReduction of costs

The spindle nut is responsible for the vertical adjustment of the work-table.The housing consists of a milled steel pipe.The spindle material is made from automatic machine steel with a surface roughness of Ra=0,8µm

The permanent axial load is 224 lbf with a spindle speed of n = 23 rpm.An axial load of 450 lbf (total 674 lbf) has an effect in addition on the spindle nutfor the duration of 120sec. every 180sec.After this exposure time the cycle starts from its original position.The ambient temperature variates between -55°C and +40°C.

A spindle nut made from ZX-100K with an acme thread TR28x3 is employed here.The nut is 0,9055 in long. The nut works in dry run and is therefore maintenance-free.

This application has passed practical tests under excessive strain and with a switch-on duration of 100 %.These practical tests have revealed that the nut, in view of the required lifespan, neither shows wear norplastic deformation in spite of this strain. The nut has been employed since 1996.
