However, there are few companies that produce this type of reducer in China, and they cannot meet the market demand. Shanghai Ji Long Heavy Industry Machinery Co., Ltd. develops a flat surface secondary enveloping hourglass worm reducer for TOP type paper cutters, which conforms to the trend of market development.
The core technology of the flat secondary enveloping hourglass worm reducer for TOP type paper cutters developed by Shanghai Union Vertical Heavy Industry Machinery Co., Ltd .:
According to the differential geometry and the meshing principle of toroidal worm, the equations of instantaneous contact line equation, undercutting limit curve and non-working area discriminating curve were deduced. Based on this, the parameters of toroidal worm deputy were optimized to avoid the tooth. Face interference and tip tops increase the area of â€‹â€‹the contact area and increase the load carrying capacity. In order to prevent the impact and vibration of the meshing worm, the worm's inlet and outlet were reversed.
The innovations of the planar double enveloping toroidal worm reducer for TOP type paper cutters developed by Shanghai Union Vertical Heavy Industries Co., Ltd .:
1. The worm parameters are optimized and designed, with large contact area and high efficiency.
2. The box body is made of ductile iron, which greatly improves the steel rigidity and shock resistance of the box and meets the requirements of large cutting force and intermittent work of the cutting machine.
3, the overall structure of compact, exquisite appearance and reasonable;
4, according to customer needs using spline shaft input, solid shaft output, flange mounting structure;
5, has a long life and other characteristics, is an energy saving and environmental protection products.
The phased results achieved by the Plane Double Enveloping Hourglass Worm Reducer for the TOP Type Paper Cutter developed by Shanghai Union Vertical Heavy Industry Machinery Co., Ltd :
1, the formation of TOP100,125,140 four models more than ten kinds of speed ratio reducer;
2. The products formed have entered sales and have been successfully applied to the equipments of Wenzhou Daishi Printing Machinery Co., Ltd., Zhejiang Shenda Printing Machinery Co., Ltd., etc., satisfying the needs of customers, gaining praise from customers, and having user reports;
3. One invention patent: A four-linkage toroidal worm CNC lathe grinding machine and its processing method, patent number .0, has entered the stage of substantive examination.
