摘要： The present invention refers to a method for manufacturing a track link for a running gear of a tracked vehicle, comprising the following method steps:
P1) providing a forging blank of steel,
P2) hot forging the forging blank to produce a track link blank and hot trimming of the track link blank to form at least a wheel tread part of the track link blank,
P3) quenching the track link blank to a temperature T1,
P4) low temperature tempering the track link blank at a temperature of approximately 200 °C,
P5) finish machining the tempered track link blank to produce the final shape of the track link. In order to invention to provide a track link production method which allows the cost efficient and lean production of track links, wherein the track link material has high hardness, high tensile strength and high toughness in combination with each other, it is suggested that the steel of the forging blank has the following composition (in % by weight):
0,25 - 0,33 % Carbon (C),
0.75 - 1.05 % Manganese (Mn),
0.15 - 0.35 % Silicon (Si),
0.75 - 0.85 % Molybdenum (Mo),
0.65 - 0.95 % Chromium (Cr),
0.65 - 0.95 % Nickel (Ni),
0.02 - 0.05 % Niobium (Nb),
optionally up to a maximum of 0.015 % Phosporus (P),
optionally up to a maximum of 0.005 % Sulphur (S),
optionally up to a maximum of 0.2 % Copper (Cu),
optionally up to a maximum of 0.005 % Calcium (Ca),
the balance being iron and unavoidable impurities.-

摘要： The invention pertains to a device for monitoring the lubrication condition of the bearing of a track roller (1) of a running gear of a tracked vehicle by means of temperature monitoring, wherein the track roller (1) has at least one bearing journal (2), wherein the track roller (1) is mounted in a frame (3) of the tracked vehicle via the bearing journal (2), wherein a sensor arrangement (4) is arranged in the region of the bearing journal (2), wherein the sensor arrangement (4) is set up to transmit temperature data measured by the sensor arrangement (4) wirelessly to a further processing device (5). In order to provide a device with which both existing tracked vehicles can be retrofitted and new vehicles can be equipped in a simple and cost-effective manner, the invention suggests the sensor arrangement (4) is arranged on a fastening screw (6), wherein the fastening screw (6) is screwed into a threaded bore (7) provided in the bearing journal (2), wherein the track roller (1) is fastened to an element (8) of the frame (3) by means of the fastening screw (6), wherein the sensor arrangement (4) comprises a temperature sensor (9), with which instantaneous temperature data can be measured, wherein the sensor arrangement (4) comprises an RFID transponder (10) with which the temperature data can be acquired, wherein a reader (11) is provided at a distance from the RFID transponder (10) suitable for reading out the acquired temperature data, and wherein the reader (11) is configured for transmitting the temperature data to the further processing device (5) for further processing.
