Embodiment 1

[0023] This embodiment discloses a process for bevel gear finishing by centrifugal abrasive flow tumbling and finishing. Realize the smoothing of the bevel gear tooth surface, and realize the step-by-step processing from rough finishing to fine finishing to reduce the effect of surface roughness. During processing, the barrel such as figure 1 As shown, it rotates around its axis in the direction of the V barrel, and the bevel gear rotates around its axis in the direction of the arrow in the figure. The velocity V direction in the figure is the instantaneous velocity direction of the particles in the abrasive flow at their position in the barrel. The tooth surface is cut and finished through the relative movement between the abrasive and the tooth surface. At the same time, the rotational movement of the bevel gear around its axis ensures the uniformity of the tooth surface processing of all gear teeth.

Embodiment 2

[0027] This embodiment discloses a process for machining bevel gears by centrifugal abrasive flow tumbling and finishing. The inventive concept of processing bevel gears is the same as that of Embodiment 1. During rough finishing and finishing finishing, the ratio of the total amount of abrasive added to the volume of the barrel is 0.6, the ratio a of the tooling spindle speed to the barrel speed is 0, and the processing time is 20 minutes.

Embodiment 3

[0029] This embodiment discloses a process for machining bevel gears by centrifugal abrasive flow tumbling and finishing. The inventive concept of processing bevel gears is the same as that of Embodiment 1. During rough finishing and finishing finishing, the ratio of the total amount of abrasive added to the volume of the barrel is 0.65, and the ratio a of the tooling spindle speed to the barrel speed is -0.5, where the tooling spindle speed is set at 10-20r / min, and the processing time is 30min.

Abstract

The invention discloses a process for finishing a bevel gear through centrifugal abrasive flow barreling. The process comprises the steps of tooth groove parameter determination, bevel gear installation scheme determination, coarse finishing process parameter determination and implementation, fine finishing process parameter determination and implementation, roughness testing and tooth profile detection. According to finishing of the bevel gear in the invention, after a gear grinding technology is finished or after the gear grinding technology is finished and a fine shot blasting technology is conducted, finishing of the tooth surface of the bevel gear is achieved through abrasive flow machining, so surface appearance distribution of the bevel gear is optimized, and then the effect of reducing the roughness of the tooth surface is achieved; during machining of the bevel gear, a material barrel rotates to drive an abrasive to form an abrasive flow field rotating around the center of the material barrel, and abrasive particles in the abrasive flow and a to-be-machined surface form relative motion so as to cut the to-be-machined surface; and as the material barrel rotates, a tool main shaft keeps still, so the tooth face of the tooth groove keeps parallel to the speed direction of the abrasive flow, and therefore, processing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the related technical field of finishing processing, in particular to a process for centrifugal grinding and finishing processing of bevel gears by centrifugal abrasive flow rolling. Background technique [0002] The surface quality of the gear has a great influence on the wear resistance, fatigue resistance, corrosion resistance and contact stiffness of the gear parts, as well as the service life and reliability. With the development of machinery manufacturing industry and the needs of industrial production, the requirements for the surface quality of gear parts are gradually increasing. At present, the surface quality of gears is mainly improved by means of grinding, and it is necessary to process different grinding wheel shapes for different surfaces. There are problems such as high processing costs and complicated technical means, especially for gear parts with complex surface shapes. It is difficult to meet the needs of l...
