Abstract

The invention discloses a crank set driving device capable of being assembled. The crank set driving device comprises a plurality of cranks. The cranks are respectively provided with a connecting shaft. The connecting shafts are sleeved with one ends of connecting legs, and the connecting legs can rotate around the connecting shafts. Every two cranks are connected through a connecting rod, and the two ends of each connecting rod are connected with the connecting legs of the cranks corresponding to the connecting rod respectively. According to the crank set driving device, through matching of the connecting legs and the connecting rods, the multiple cranks are connected together to form a crank set driving system; because the connecting shafts are sleeved with the connecting legs, the whole device is convenient to assemble when used, and all the components are connected in a detachable mode. The crank set driving device is low in cost, simple in structure, convenient to machine and manufacture, easy and convenient to lubricate and extremely high in practical value, meets requirements of light load occasions and does not have special requirements for work environment.

Description

technical field [0001] The invention belongs to the field of light industrial machinery, and in particular relates to a crank group drive device which can be assembled. Background technique [0002] At present, the output value of pharmaceutical packaging machinery, tobacco machinery and printing machinery industries is large, and the import and export volume is also large, but the weight of independent intellectual property rights in these products is very low. According to the working principles of these working machines, there are many parallel shafts that need to rotate synchronously, so the crank group driving device that can be assembled has a very broad application prospect. However, in these light industrial machinery, if gears and other transmission forms are used to drive multiple parallel shafts synchronously, there are many disadvantages: [0003] 1. The combination of multiple gears requires a large space, and its supporting and lubricating devices are also com...
