Translation of "Heat wheel" in German

The method embodying the invention is characterized by the fact that, after the solution heat treatment, the wheel disk is cooled faster in a center area than at the edges.

To this end, after shaping and solution heat treatment, the wheel 1 is sprayed with cooling water from nozzles 2, 3 and 4 to cool the wheel, from approximately 550° C. to room temperature.

After the solution heat treatment, the wheel is removed and placed in a calibration fixture which in the present invention comprises two dies located on a common arbor.

Arranged along the heat wheel (52) are radiant heaters (57) and fans (58) for temperature treatment of the preforms (1).

This is intended to prevent a rise in the bearing temperature which has taken place in the past also being extrapolated according to a braking process because the input of heat into the wheel bearing is reduced by the braking operation.

However, if according to case c) the vehicle speed was increased within the past time interval, it is to be expected that the input of heat into the wheel bearing increases further, with the result that a factor is set to be greater than the predefined value in order to be able to allow for this influence.

This is intended to prevent a rise in the wheel set bearing temperature which has taken place in the past from also being extrapolated after a braking process because the input of heat into the wheel set bearing 1 is reduced by the braking operation.

The conduction of heat from the housing 4 of the wheel set bearings 1 with the thermal capacity C 2 to the wheel set bearings 1 (C 1) is symbolized by the resistance R 12, and the conduction of heat to a wheel set bearing cover 6 with the thermal capacity C 3 is symbolized by the resistance R 23 .

According to one embodiment of the invention, at least two of the heat-conducting paths have different thermal conduction properties, and so the heat from the wheel bearing is conducted to the corresponding temperature-measuring elements at different rates.

In order to transmit heat from the wheel bearing to the outer side of the wheel cover, at least one heat-conducting element is preferably disposed between the wheel bearing and the wheel cover, which heat-conducting element is preferably formed of metal.

The conduction of heat from the wheel set bearing housing 4 of the wheel set bearings 1 with the thermal capacitance C 2 to the wheel set bearings 1 (C 1) is symbolized by the resistance R 12, and the conduction of heat to a wheel set bearing cover 6 with the thermal capacitance C 3 is symbolized by the resistance R 23 .

The calculation model is based on the ideal that the input of heat at the wheel set bearing by conduction of heat is transmitted to the measurement point by conduction of heat and transfer of heat and, furthermore, influenced by external factors such as, for example, the cooling of the components of the wheel set by the dynamic wind owing to the speed of the rail vehicle or the heating of the components by a high ambient temperature.

Container 11, fluid 12 and the formation of cover 13 or of the second container element 9 are matched to one another such that when a predetermined critical temperature loading is exceeded, which, for example, may be a sign of impending breakdown of the wheel bearing 3, the heat from the wheel bearing 3 is transferred via the axle end 4 onto the container 11 in which the fluid 12 expands such that the cover 13 is irreversibly bulged outwardly and that with further temperature rise due to continued driving operation after breaking of the rated yield point 14, the fluid 12 escapes from the container 11 .

Starting at a preform inlet (54), the preforms (1) are transported by transfer wheels (55, 56) into the area of the heat wheel (52).

Then the heat is extracted from the exhaust air by means of a copper heat exchanger wheel so it can be used to heat the supply air during the cold part of the year.

Several heating elements 310 are arranged at the heating wheel 307 .

Heat resistant wheels are also made to special customer orders.

For example, you can find heat-resistant wheels for mobile oven racks in bakeries.

For example, the heating wheel 101 can be a STIR oven.

Further new extras for the R-Class include a remote-controlled auxiliary heater and an electric steering wheel heating system.

The heated preforms are transferred from the heating wheel 101 to the blow molding wheel 102 via a transfer element 105 .

The heating wheel 101 comprises several heating elements in the form of heating chambers 103 for heating the preforms.

DE 31 30 129 A1 describes this problem and suggests, as the solution, a heating wheel which rotates between heating boxes fixedly arranged on the outer circumference with a close pitch for the parisons or the retaining mandrels receiving said parisons, from which wheel they are transferred by a transfer wheel to a blow wheel on which the blow molds are arranged in a pitch adapted to the size of said molds.
