Locomotive traction motor axle suspension bush machining device

Abstract

The invention discloses a locomotive traction motor axle suspension bush machining device, relates to devices for finish machining of an inner circle surface of an axle suspension bush of a locomotive traction motor, and mainly aims at solving the problems that due to the fact that an existing axle suspension bush is in the structure of two semi-circles, the existing axle suspension bush has certain deformation in a natural state after being machined so that the working performance of the existing axle suspension bush is affected, and the hidden danger of adhesion of the existing axle suspension bush and serious shaft locking in a running process can be caused. According to the locomotive traction motor axle suspension bush machining device, an upper tire body and a lower tire body form an inner cavity which is matched with the axle suspension bush in shape, one connecting edge of the upper tire body and one connecting edge of the lower tire body are connected through a hinge pin, the other connecting edge of the upper tire body and the other connecting edge of the lower tire body are fixedly connected through a bolt. Due to the fact that the closed space formed by the upper tire body and the lower tire body is in a hollow cylindrical shape and completely simulates an installing surface of the axle suspension bush of the locomotive traction motor, the axle suspension bush to be machined is installed in the inner circle surface formed by the upper tire body and the lower tire body in the machining process, and therefore the operation reliability of the axle suspension bush is improved, and the accidents of the adhesion of the axle suspension bush and the shaft locking in the running process are eradicated. The locomotive traction motor axle suspension bush machining device is simple to install, convenient to machine and capable of guaranteeing machining quality.

Description

technical field [0001] The invention relates to a bearing bush processing device of a traction motor of a locomotive, which is mainly used for finishing the inner circular surface of a Babbitt alloy of a traction motor of a locomotive traction motor. Background technique [0002] Usually, the suspension of the locomotive motor shaft and the car body is connected by rolling bearings or sliding bearings. The sliding bearing connection has the characteristics of high bearing capacity, good shock resistance, stable and reliable operation, low noise, and long life. It is widely used in locomotive motor drive system. Because the bearing capacity of the bearing pad of the locomotive motor is large, the working environment is harsh, and the lubrication is poor during the start-up process, the contact accuracy between the Babbitt alloy layer of the bearing pad and the locomotive wheel axle is extremely critical. The shape and working accuracy of the inner surface directly affect the...

AI Technical Summary

Problems solved by technology

Because the bearing capacity of the bearing pad of the locomotive motor is large, the working environment is harsh, and the lubrication is poor during the start-up process, the contact accuracy between the Babbitt alloy layer of the bearing pad and the locomotive wheel axle is extremely critical, and the matching accuracy between the outer circle of the bearing pad and the box is critical The shape and working accuracy of the inner surface directly affect the bearing pad. At the same time, the bearing pad has two semicircular structures, and there is a certain deformation in the natural state after processing. These factors directly affect the working performance of the babbitt alloy inner surface of the bearing pad. The result is Severe driving hazards caused by tile sticking and shaft locking
