Abstract

Usage: in the field of mechanical engineering technology and can be used for machining holes or other surfaces of gears in turning and grinding operations when centered on the lateral surfaces of the teeth. SUMMARY OF THE INVENTION: The centering elements 1 located in the tooth cavities of the machined wheel 2 are mounted on axles 3 and are contacted with cup springs 4 and 5, which provide elastic longitudinal displacements of the centering elements 1. Axes 3 are connected to a drive providing simultaneous coordinated rotation of the centering elements 1, which in the initial state occupy a middle position between the disk springs 4 and 5. During the rotation of the centering elements, they self-install along the cavities of the gear about the wheel due to the compression of one of the cup springs 4 and 5. With further rotation of the centering elements, the part 2 is wedged to the clutch along its base end. 1 ill. 5 (L C

Description

The invention relates to the technology of mechanical engineering, is intended for mounting and securing the gears when aligning along the side surfaces of the crown slaughter, 5

An object of the invention is to improve centering accuracy.

The drawing shows a part of a front view of the device. With a cutaway assembly for installing centering elements.

The conical rollers 1, by which the machined gears 2 are centered, are mounted on the axles 3. The axes are connected to a common drive and provide coordinated simultaneous rotation of the conical rollers, which are in contact with the disk springs 4 and 5, providing their longitudinal longitudinal elastic movements on axis x 3,

The device operates as follows. In the initial state, the conical rollers 1 occupy an average (nominal) position on the axes 3 between the Belleville springs 4 and 5. The conical surfaces of the rollers 1 have the greatest distance from the center of the device. The presence of a gap between the conical surfaces of the rollers 1 and the side surfaces of the tooth cavities of the gear being machined 2 allows the device to be installed with radial errors and pitch deviations of the teeth of the crown. By engaging the drive through axles 3, the concurrent simultaneous rotation is transmitted to the conical rollers 1.

In the process of rotation of the conical rollers 1 due to their eccentric arrangement on the axes 3 gradually

the radius of the surfaces aligning the gear wheel 2 increases. After the conical surfaces of the rollers 1 come in contact with the side surfaces of the tooth depressions of the wheel 2, the self-alignment of the rollers 1 in the depressions occurs in accordance with the actual step deviation of each of the teeth. Compensation of tooth pitch deviations of the wheel 2 is carried out by longitudinal displacements of the tapered rollers 1 on the axles 3 relative to the nominal position and compression of one of the disk springs 4 and 5.

With further rotation of the bevel rollers, the final gear spalls; 2 and its fixing on the base end. - The detachment of the machined gear wheel 2 is carried out by reversing the rotation of the bevel rollers 1. After the bevel rollers 1 are disengaged from the teeth of the wheel 2, they are returned to the nominal position on the axles 3 by means of cup springs 4 and 5.
