Rolling wheel connecting shaft

Abstract

The invention discloses a rolling wheel connecting shaft. The whole length of the connecting shaft ranges from 45.1 mm to 45.3 mm, a cylindrical shaft is arranged at one end, a 45-degree chamber being0.65 mm to 0.75 mm is arranged at the end of the cylindrical shaft, the diameter of the cylindrical shaft ranges from 9.65 mm to 9.67 mm, the surface roughness is 1.6, the other end of the connectingshaft is a ball, the diameter of the ball ranges from 8.2 mm to 8.3 mm, the surface roughness is 3.2, a transition body is arranged between the cylindrical shaft and the ball and is in a cone shape,an arc chamber with the radius being 2.5 mm is arranged at the connecting position, the surface roughness is 3.2, and a center hole with the diameter being 1.95 mm to 2.05 mm is formed in the top of the ball; the rolling wheel connecting shaft is made of 20CrMo and is subject to carburizing and quenching treatment, the surface is hard, and is resistant to wear, the interior is tough, due to the structure, the performance and safety of products are improved, the service life is prolonged, use is convenient, operation is convenient, stability is good, reliability is high, machining is easy, costis low, yield is high, dual effects of detaching and connecting positioning and clamping are obviously improved, utilization value of the industry is achieved, production and machining are convenient, and batched production and popularization are easy.

Description

Technical field: [0001] The invention relates to the field of coupling shafts, in particular to a roller coupling shaft. Background technique: [0002] The roller coupling shaft is an important part commonly used in motorcycle parts, auto parts, ships, and industrial sewing machine parts. The roller coupling shaft has high requirements for force and friction, large deformation, high strength and precision of parts, and low process complexity. Higher, at present, the traditional cutting process is generally used to make the coupling shaft, which is wasteful and labor-intensive, and the product is easy to wear or break. [0003] For this reason, a new structure of automobile motor transmission coupling shaft is needed, which can not only meet the current advanced precision cold forging manufacturing, but also has better strength and precision. Invention content: [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a roll...
