Embodiment Construction

[0017] When implementing it:

[0018] Such as Figure 1-3 As shown, a driving sprocket includes a sprocket 2 and a hub 1, and the sprocket 2 and the hub 1 are fixed by a fixing member 3. The sprocket 2 is composed of several toothed units 4, and each Each tooth-shaped unit 4 is divided into left curve 14 and right curve 11, and described left curve 14 and right curve 11 are mirror-symmetrical with respect to central axis, and described left curve 14 is formed by edge line 8, circular arc A9, connecting line 13 and circle The arcs B10 are connected in sequence, the center of the arc A9 is inside the left curve 14, the center of the arc B10 is outside the left curve 14, the edge line 8 and the connecting line 13 are straight lines, and the left An arc C12 is connected between the arc B10 on the curve 14 and the arc B10 on the right curve 11 , and the center of the arc C12 is located inside the tooth-shaped unit 4 . The present invention adopts the most advanced three-arc-two-s...

Abstract

The invention discloses a drive sprocket which comprises a chain wheel and a hub. The chain wheel and the hub are fixed through a fixing piece, the chain wheel is formed by a plurality of tooth-shaped units, each tooth-shaped unit is divided into a left curve and a right curve, and each left curve and the corresponding right curve are in mirror symmetry with respect to a center shaft; each left curve is formed by sequentially connecting an edge line, an arc A, a connecting line and an arc B, the circle center of each arc A is located on the inner side of the corresponding left curve, the circle center of each arc B is located on the outer side of the corresponding left curve, and the edge lines and the connecting lines are straight lines; and an arc C is connected between the arc B on each left curve and an arc B on the corresponding right curve, and the circle center of each arc C is located on the inner side of the corresponding tooth-shaped unit. The drive sprocket has the beneficial effects that it is guaranteed that chain joints can stably and freely enter and exit from meshing, impact and contact stress of the chain joints during meshing are reduced, the service life is greatly prolonged, and the high strength and abrasive resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a driving sprocket. Background technique [0002] The drive sprocket is used to drive the chain to move the material. In the prior art, the drive sprocket cannot enter and exit meshing accurately, smoothly and freely, and has a short service life, and does not have sufficient strength and wear resistance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a drive sprocket with high strength and wear resistance, which ensures that the chain enters and exits meshing smoothly and freely with energy saving, reduces the impact and contact stress of the chain links during meshing, greatly prolongs the service life . [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a driving sprocket, including a sprocket and a hub, the sprocket and the hub...
