Description

Technical Field

[0001] The utility model belongs to the technical field of wheel set maintenance, and more specifically, particularly relates to a locomotive wheel set positioning device. Background Art

[0002] When inspecting locomotive wheels, it is generally necessary to position the locomotive wheels and then perform a dynamic balance test. This is done by placing the wheels on a dynamic balancing test machine, centering the wheels, and using the drive system of the dynamic balancing test machine to drive the wheels to rotate, thereby achieving a dynamic balance test of the wheels.

[0003] The existing application number is: CN202123405124.2. The utility model belongs to the technical field of dynamic balancing test of moving wheel pairs, and in particular, it is a gearbox sway suppression device for dynamic balancing test of moving wheel pairs. Aiming at the problem that the sway suppression mechanism of the gearbox sway suppression device for dynamic balancing test of moving wheel pairs in the prior art is not convenient for disassembly and adjustment, and it is difficult to meet the needs of different usage conditions, the following scheme is proposed, which includes a base, a moving wheel pair, a gearbox and a sway suppression mechanism. Brackets are fixedly installed on both sides of the top of the base, and the moving wheel pair is arranged above the two brackets. The sway suppression mechanism includes a bottom plate, a rack and a gear. The gearbox is arranged above the bottom plate, and a fixing frame is fixedly installed on the top of the bottom plate. The utility model fixes the sway suppression mechanism in the gearbox sway suppression device for dynamic balancing test of moving wheel pairs through the cooperation of the clamping rod and the positioning rod, and is convenient for moving, adjusting and disassembling it, which is convenient for use.

[0004] Based on the above, during the existing dynamic balancing test on wheelsets, since many wheelsets being repaired have rust attached to their surfaces, the rust on the wheelset surfaces can easily fall off onto the bracket of the dynamic balancing machine when the wheelset rotates.
