Abstract

The invention discloses a self-lubrication sealing structure for a gear box. The self-lubrication sealing structure for the gear box is used on a rail transit line maintaining operation vehicle. The self-lubrication sealing structure for the gear box comprises a box body, a first bearing pedestal, a second bearing pedestal, a sealing ring, a sealing cover, a sliding sleeve, a framework oil seal, a first supporting bearing, a second supporting bearing and a gear shaft. The portions, above the first bearing pedestal and the second bearing pedestal, of the two inner side walls of the box body are provided with a first oil collecting groove and a second oil collecting groove respectively. The bottom of the first bearing pedestal and the bottom of the second bearing pedestal are fixedly connected with a first oil pool and a second oil pool respectively, and a non-contact type labyrinth sealing structure formed by combining two axial gap seals, an axial gap sealing annular groove and a radial oil swing flange, and an oil collecting lubrication structure are formed. The self-lubrication sealing structure for the gear box is compact in arrangement, simple in structure and capable of meeting the requirements of high-speed and low-speed operating conditions of the rail transit line maintaining operation vehicle at the same time.

Description

technical field [0001] The invention relates to a gear transmission device on a rail transit line maintenance vehicle, in particular to a lubricating and sealing structure of a traveling gear box. Background technique [0002] Rail transit line maintenance vehicles have two working states, one is the high-speed running state (100km / h), which is used to drive the train to the place to be operated, and the other is the low-constant speed operating state (0-10km / h). h), for line maintenance operations. Gearboxes (especially electric transmission gearboxes), as their driving components, need to meet the requirements of good lubrication and reliable sealing under high and low speed conditions at the same time. Due to space constraints, gearboxes are installed with built-in or external forced lubrication systems. The structure has not been realized for a long time, so it is urgent to study a simple structure of the gearbox self-lubricating sealing structure to meet its functional...
