Abstract

The invention belongs to the technical field of gear production and machining, particularly relates to a shot peening strengthening device capable of improving stress distribution on the surface of a gear. Aiming at the problems that existing shot peening strengthening equipment is complex in structure, shots are not uniformly ejected on the gear, workpiece taking and feeding operations are complex, and stains on the surface of the gear cannot be removed, the following scheme is provided, the shot peening strengthening device comprises a box body, a blade disc is rotationally connected to the inner wall of the box body, a power assembly for driving the blade disc to rotate intermittently is arranged on the box body, and three fan-shaped cavities are evenly formed in the blade disc. The shot peening strengthening device is simple in structure, the gear to be strengthened rotates at a constant speed while a shot peening machine works to eject shots, the shots are sprayed to the surface of a to-be-strengthened gear more uniformly and circularly, the strengthening work efficiency is improved through the circulating design, and through an arranged annular hairbrush, surface stain removal can be carried out on the to-be-strengthened gear, and the strengthening effect of device is improved.

Description

technical field [0001] The invention relates to the technical field of gear production and processing, in particular to a shot peening device capable of improving the stress distribution on the gear surface. Background technique [0002] Shot peening, also known as shot peening, is one of the effective methods to reduce fatigue and improve life of parts. Shot peening is to spray high-speed projectile flow onto the surface of parts to make the surface of parts plastically deform and form a strengthening layer with a certain thickness. High residual stress is formed in the strengthening layer. Due to the existence of compressive stress on the surface of the part, part of the stress can be offset when the part is under load, thereby improving the fatigue strength of the part. In order to improve the stress distribution on the surface of the gear during the production and processing of the gear, it is necessary to The gears are shot peened. [0003] The existing shot peening eq...
