Assembly system of integrated gearbox

Abstract

The invention provides an assembly system of an integrated gearbox, which comprises a box body overturning device and a swinging device, wherein the box body overturning device comprises a support; a first bearing pedestal and a second bearing pedestal are horizontally and oppositely arranged on the support; a driving shaft and a driven shaft are respectively arranged on the first bearing pedestal; executive parts used for clamping the box body and driving the box body to overturn are respectively and fixedly arranged at the end parts of the driving shaft and the driven shaft; the swinging device comprises an upper clamping plate and a lower clamping plate which are used for clamping a gear ring, and an adjusting and supporting device which is used for vertically positioning the upper andthe lower clamping plates and driving the upper and the lower clamping plates to move in opposite directions; and a hanging bracket used for being connected with an overhead traveling crane is also fixedly arranged at the top of the adjusting and supporting device. By adopting the assembly system of the integrated gearbox, which is provided by the invention, the gear ring can be accurately positioned while being mounted in the box body, so the assembly quality and the assembly efficiency are improved; and meanwhile, by adopting the box body overturning device, the assembly operation is also facilitated, the labor burdens of workers are lightened, and the assembly efficiency of the integrated gearbox is improved.

Description

technical field [0001] The invention relates to railway vehicle parts assembly technology, in particular to an integrated gearbox assembly system. Background technique [0002] The structure of the split locomotive gearbox includes an upper box and a lower box. The assembly process is relatively convenient. After the motor, gear and gear shaft are assembled, the upper box and the lower box can be boxed. The gear and the box The positional relationship between the bodies is then determined. However, in order to improve the rigidity of the load-bearing gearbox, the gearbox in the prior art adopts an integrated box structure. The assembly of the gearbox with this structure requires that the gear be installed first, and then the gear shaft pass through the box. The hole on the body used to match the gear shaft and the hole on the gear, that is, it is necessary to ensure that after the gear is installed in the gearbox, the center axis of the gear and the center axis of the insta...

Problems solved by technology

First, the leveling process of the three tops 5 used to support the box is cumbersome and takes a long time; second, because the ring gear 12 is adjusted in the direction X to ensure that the ring gear The positioning of 12 along the direction X, and the positioning in the direction perpendicular to the direction X in the plane where the ring gear 12 is located, is realized by pushing the ring gear 12 to move along this direction by manpower, that is, the gear can only be guaranteed by the worker's operating experience. The positioning of the ring 12 in the direction perpendicular to the direction X in the plane where the ring gear 12 is located cannot guarantee the positioning accuracy of the ring gear 12 in this direction, thus causing the central axis of the ring gear 12 to deviate from the installation axis used to install the gear shaft 2 The central axis of the hole makes the subsequent installation of the tooth core 11, the labyrinth ring 4, and the bearing 23 very difficult. It is necessary to repeatedly move the position of the ring gear 12, which greatly increases the labor intensity of the workers and also affects the assembly quality and efficiency; the third , since the box body is placed horizontally with the bottom facing one side, that is, the side that needs to be installed with the transport protection plate faces down, so that workers can only look up at the assembly transport protection plate, which is very unfavorable for operation, low efficiency and high labor intensity

In short, the integrated gearbox assembly scheme adopted in the prior art not only has low efficiency and high labor intensity, but also cannot guarantee the accuracy and quality of assembly
