Abstract
The invention discloses an escalator drive sprocket and a manufacture method thereof. The escalator drive sprocket comprises a wheel spoke and a tooth ring, the tooth ring sleeves the outer side of the wheel spoke, and the wheel spoke is connected and fixed with the tooth ring through intermittent welding. Compared with the drive sprocket in the prior art which is obtained through casting or cutting, and in which the wheel spoke and the tooth ring are connected into one body, the escalator drive sprocket provided by the invention is advantaged in that the wheel spoke and the tooth ring can be made of steel materials in different kinds, and are separately manufactured through an existing relatively-mature technology. According to invention, shrinkage cavity and sand hole defects, of a casting type drive sprocket, caused by integral body casting can be prevented, defects of large machining amount, high cost and the like, of a cutting type drive sprocket, caused by integral body cutting can be prevented, and therefore the escalator drive sprocket is high in product molding ratio, low in cost and low in machining amount.
Description
Technical field
The present invention relates to escalator spare and accessory parts technical field, especially relate to a kind of drive chain of escalator wheel and manufacture method thereof.
Background technology
The existing sprocket wheel being applied to escalator field has cast type drive sprocket and plate cutting formula drive sprocket, makes a concrete analysis of respectively below to these two kinds of drive sprockets:
Referring to Fig. 1,2, Fig. 1 is drive sprocket blank 10 schematic diagram be made into by casting method by base material, and Fig. 2 is drive sprocket 20 finished product drive sprocket blank 10 being removed the formation of a small amount of material by cutting processing mode.After casting forms drive sprocket blank 10, only need the sub-fraction removing sprocket tooth part material and centre of sprocket can form spoke 21, gear ring 22 and pin-and-hole 23.So, processing capacity is few, and drive sprocket material removing rate is low.Therefore cost is comparatively cheap, and drive sprocket 20 weight is little.But because this kind of drive sprocket 20 is processed by blank 10, so easily there is the foundry defect such as shrinkage cavity, sand holes, especially for relatively large drive sprocket, shrinkage cavity, sand holes defect are more difficult to control.And if these shrinkage cavities, sand holes occur in the teeth portion of sprocket wheel or the higher position of other stress, then the as easy as rolling off a log drive sprocket 20 that causes is scrapped, and makes the reject rate of drive sprocket 20 higher.
Be the plate iron schematic diagram preparing to carry out cutting manufacture drive sprocket referring again to Fig. 3,4, Fig. 3, plate iron 30 cuts to manufacture the schematic diagram after forming drive sprocket 40 finished product by Fig. 4.By cutting plate iron 30, form spoke 41, gear ring 42 and pin-and-hole 43, manufacture and obtain drive sprocket 40, the yield rate obtaining drive sprocket 40 is higher.But because this drive sprocket 40 directly adopts plate iron 30 to be processed by cutting mode, plate iron 30 own wt is large, and cause processing capacity very big, material removing rate is high, and manufacturing cost is higher., although drive sprocket 40 internal defect greatly reduces relatively, but still there is the unsound defect of plate iron 30 interior tissue in the drive sprocket 20 that the drive sprocket 40 that plate iron 30 cutting obtains is formed relative to casting.
Summary of the invention
Based on this, the invention reside in the defect overcoming prior art, a kind of drive chain of escalator wheel and the manufacture method thereof that can avoid the internal defect such as shrinkage cavity, sand holes are provided.
Its technical scheme is as follows: a kind of drive chain of escalator wheel, comprising: spoke; And gear ring, described gear ring is set in outside described spoke, and fixing by being intermittently welded to connect between described spoke and described gear ring.
