Abstract

The invention relates to a bearing plate and a heat treatment technology thereof, and belongs to the technical field of urban light rail traffic. The bearing plate is installed on a straddle-type urban light rail traffic PC beam support. The bearing plate comprises a bearing plate body, and the surface of the bearing plate body is subjected to nitriding heat treatment to form an anti-corrosion andanti-wear layer. The anti-corrosion and anti-wear layer performance of the bearing plate can be improved, the service life of the bearing plate can be prolonged, the factors for endangering driving safety are avoided, and the train driving safety is improved.

Description

technical field [0001] The disclosure relates to the technical field of urban light rail transportation, in particular to a pressure bearing plate and a heat treatment process thereof. Background technique [0002] With the continuous development of urban light rail transportation, higher requirements are put forward for the components of urban light rail transportation. The bearing plate is an important part of the PC beam support. The pressure bearing plate is set under the PC beam support and the roller hinge shaft, and bears the full weight of the PC beam, tractor and carriage, and passengers; when the PC beam shrinks and elongates due to thermal expansion and contraction, and when the train starts and brakes, it will Hinge shaft and roller shaft produce rolling friction and sliding friction. [0003] The pressure bearing plate generally works in a harsh environment, the force is a linear load, it is easy to corrode and wear, the service life is shortened, and there are...
