When manufacturing, first by pressing equipment, the endoporus of steel plate and outer ring being cut, forming power wheel body, and form positioning groove at the inwall of endoporus; Then when power wheel body rotates, carry out feeding processing by bevel tool, form annular and split groove; Then fixed cover is inserted in endoporus, because fixed cover has the structure of boss, fixed cover one end is connected with power wheel is spacing, and close contact, the registration mast correspondence on fixed cover is inserted in corresponding positioning groove; Pass through special riveting press equipment again by registration mast riveting laterally, fix with power wheel, form outer riveting pressure point; Finally bearing and fixed cover are fixed, just completed.In power wheel production part, it is one-body molded that die cutting techniques is passed through in endoporus and outer ring, and undertaken splitting slot machining by cutter, and compared with the foundry technique of general power wheel, production efficiency increases substantially, and ensure that the right alignment of endoporus and outer ring simultaneously; Positioning groove and registration mast, structure is simple, compares, decrease the installation of registration mast, enhance productivity with general axis with the positive stop key structure of axle sleeve; The riveting fixed sturcture of fixed cover and power wheel, compares with the bolt fastening structure of bearing carrier ring with general power wheel, avoids the installation of bolt, and achieve the mechanization riveting of fixed cover and power wheel, production efficiency increases substantially, and reduces costs.
As preferably, one end of described bearing is connected with fixed cover is spacing, and the other end and the fixed cover of bearing are fixed by riveting, forms multiple interior riveting pressure point.The same with the fixed form of fixed cover and power wheel, the riveting fixed form of bearing and fixed cover, achieve the mechanization riveting of bearing and fixed cover, production efficiency improves further, reduces costs further.
As preferably, the quantity of described interior riveting pressure point is 2-8.The quantity of riveting pressure point is more, is fixedly connected with more reliable.
As preferably, to set angle that described annular splits groove dual-side be the scope of R, R is: 45 °≤R≤55 °.Prove through test, R is in this angular range, and it is both easy to process that annular splits groove, has again good intensity.
As preferably, described R=50 °.
As preferably, the quantity of described registration mast is 2-8 root.The quantity of registration mast is more, and the right alignment of fixed cover and power wheel is better, connects more reliable.
Owing to taking above-mentioned technical scheme, a kind of wire rope pulley that the utility model provides has such beneficial effect: by the combined innovation of power wheel, fixed cover and bearing and connection structure thereof, there is provided a kind of structure simple, cost is low, production efficiency is high, right alignment good be connected failure-free wire rope pulley.
