Abstract

The invention relates to the technical field of gear boxes, in particular to a gear box and a rail transit car. The gear box comprises a gear box body and a warning device arrange on the gear box body; the warning device comprises a compound sensor, a control component and an alert component; the compound component and the alert component are respectively connected with the control component in an electrical mode. The compound sensor is used for detecting vibration value, shock value and temperature value of the gear box. According to the gear box, through detecting of the compound sensor, judging of the control component and reminding of the alert component, variation amplitude, variation rule and trend of detecting physical quantity are realized, so that the data information support bias are provided for the fault diagnosis, thereby realizing the alerting function of the gear box; users can be reminded whether or not the gear box is in an effective working state; therefore, the fault frequency of the gear box in the real working state is reduced, the loss of the fault is decreased, the fault harm is relieved, the drive safety is guaranteed, and the potential risk is eliminated.

Description

technical field [0001] The invention relates to the technical field of gear boxes, in particular to a gear box and a rail transit vehicle. Background technique [0002] At present, the rail transit gearboxes used in China, such as high-speed rail, subway, urban rail vehicle gearboxes, etc., are one of the key components of rail transit vehicles. The gearbox is composed of gears, boxes, bearings and lubricating mechanisms. It is the power transmission device of rail transit vehicles and is responsible for transmitting the power of the motor to the train to enable it to run at high speed. As one of the core components of an EMU, the gearbox is one of the most important transmission links in the EMU transmission system, which is related to the driving safety of rail transit vehicles and the safety of passengers' lives and property. [0003] However, during operation, the working conditions of rail transit gearboxes are very harsh. Not only are they heavily loaded, but they are...
