Embodiment Construction

[0009] Such as figure 1 As shown, a suspension ring 1 is fixed on the suspension beam 2, and the suspension ring 1 is used to connect the driving, and a reinforcing rib 3 is fixed on the suspension beam 2 to improve the rigidity of the suspension beam 2, and suspension rods are respectively connected at both ends of the suspension beam 2 5. The boom 5 passes through the through hole on the suspension beam 2, and is connected to the suspension beam 2 with the nut 4. The through hole on the suspension beam 2 is larger than the diameter of the suspension rod 5, so that the suspension rod 5 can move up and down and swing left and right. The lower end of the boom 5 is connected with a ring 7, and the rings 7 on the two booms 5 are symmetrically fixed on the inner sides of the two booms 5, and a backing plate 6 is fixed between the ring 7 and the boom 5 for adjusting the two booms. The position between the rings 7; when in use, align the ring 7 on the boom 5 with the shaft holding b...

Abstract

The invention relates to a special device for measuring the bearing clearance of a locomotive axle suspension bearing box, and provides a device for measuring the bearing clearance of a locomotive axle suspension bearing box, for mainly solving the problems of non-uniform loading forces, measured value deviations or complicated operation and low operation efficiency by use of a conventional measuring device. The technical scheme provided by the invention is as follows: a suspension ring is fixed on a suspension beam; the two ends of the suspension beam are each connected with a suspension rod; the upper end of each suspension rod is connected with a right suspension beam through a nut, and the lower end is connected with a ring. In use, the suspension beam is positioned and placed on a jack, the ring is aligned with a hole of the axle suspension bearing box, a pin is inserted, the nut is adjusted to be in place, the jack is rotated to enable relative displacement to be generated between an axle and the axle suspension bearing box, and the displacement amount is the bearing clearance. The device for measuring the bearing clearance of the locomotive axle suspension bearing box has the advantages of simple structure, convenience use, improved efficiency and shortened operation time.

Description

technical field [0001] The invention relates to a special device for measuring the clearance of a locomotive axle shaft holding box bearing. Background technique [0002] In order to ensure the safe operation of the locomotive at high speed, the axle box bearing must have an axial clearance of 0.15-0.25MM. In order to effectively control the bearing clearance, the clearance value must be accurately measured during the assembly process. There are two main types of bearing clearance measuring devices: vertical measuring devices and horizontal measuring devices. The vertical measuring device has a simple structure and is easy to use. A jack is used to push the shaft-holding box sideways, and the moving amount is the measured value. The disadvantage is the side force, the measured value is biased. The horizontal measuring device places the workpiece on the tooling, presses the axle holding box with bolts, and pushes the axle with a screw mechanism, and the moving amount is th...
