Embodiment Construction

[0015] There is a double pitch on the meshing line of the chain plates, and three teeth are distributed on each chain plate. The outer tooth profiles of the first and third tooth profiles are straight lines, and the edge center distance is f 1 It is 0.96~0.98 times of the side-to-center distance f of the standard tooth-shaped chain link plate, the inner tooth profile is a convex curve, the amount of protrusion δ=0.01f ~0.03f, the second tooth profile is a straight tooth The formula for calculating the parameters of the chain plate is as follows: Pitch P 1 =2Pcos(180° / Z), the middle tooth profile angle α 1 =2β, tooth profile angle α 2 =2φ+2β, chain plate meshing circle diameter d=p / sin(180° / Z), chain plate tooth tip circle diameter d 1 =d-2h 1 , Where β is the corresponding sprocket tooth groove angle β=30°-(180° / Z), φ is the corresponding sprocket index angle φ=360° / Z, P is the pitch of the standard toothed chain, Z is the corresponding The number of teeth of the sprocket, f is t...

Abstract

The invention relates to a double-pitch time-sharing meshed tooth-shape chain board, belonging to the field of mechanical design and manufacture and chain driving. The chain board has double pitch on a meshing line, three teeth are distributed on each piece of the chain board, the outer tooth profile lines of the first and the third tooth profiles are straight lines, the apothem f1 of the chain board is 0.96-0.98 times than the apothem f of the standard tooth-shape chain board, the inner tooth profile line is a convex curve with a protrusion delta equal to 0.01f-0.03f, and the tooth profile line of the second tooth is a straight line tooth profile. The invention has the following advantages: when transporting and driving the same load, the chain board has stable tooth mesh-in and mesh-out, small shock and vibration and noise, less material consumption, high motion precision and good reliability, thus the chain board is particularly suitable for the transportation of the parts in an automobile assembly.

Description

Technical field [0001] The invention belongs to the field of mechanical design and manufacture and chain transmission, and is suitable for smooth conveying on various conveying lines. Background technique [0002] Toothed chain is a kind of important mechanical basic part which is widely used. Due to the characteristics of low noise, high reliability and high movement precision, toothed chains have been widely used in automotive engine timing systems, oil pump systems, transmission systems, steam turbines, aircraft, and machine tools in recent years, especially in various automated production lines. It has played an irreplaceable role with its unique advantages. Its transmission form is better than toothed belt transmission, gear transmission and roller chain transmission. The traditional standard toothed chain is that each chain plate has a single pitch double tooth profile. The outer line of the chain plate is a linear tooth profile, and the inner side is a straight line or a...
