In the design of the gear, it is determined that the transmission gear adopts a straight tooth or a helical gear, and the closed design or the open design is adopted. Due to the complicated manual calculation, the chart data is troublesome and the hand calculation design is one-off. The comprehensive comparison of the design schemes cannot be performed quantitatively and on the selection of each parameter, so the design result is often not optimal. All parameters can be provided quickly and accurately according to the designer's intent.
Using this program, you can completely separate from the design manual, input the original data according to the conditions specified in the design task book, and provide the data and materials related to the input in the form of Chinese characters to realize the man-machine dialogue, so that each parameter is generated by the program.
When gears are designed, there are many curved and straight lines, and the processing of the line drawings directly affects the design accuracy of the gears. The program adopts a straight line approximation curve, and its processing, Messo is simple, the memory occupancy is small, the calculation time is short, and the calculation precision is sufficiently high. In the case of cast iron, normalization, quenching and tempering, carburizing and quenching, and nitriding. There are five graphs for the bending contact allowable stress, the material created in each heat treatment case.
The allowable stress is a wireframe. The processing of this complicated large figure is: the stress line frame program is used to take the value to simplify it into a line; the heat treatment condition and the material type are double subscript variables, and the double subscript is used to The five figures are superimposed on one piece. Thus, the ten graphs are replaced by two sets of double subscript arrays, and the wireframe is only replaced by straight lines. The program is short, the calculation efficiency is high, the input code is simple, the retrieval data is convenient and rapid, and the accuracy is not reduced (the calculated allowable stress) The value is lower than the median and median results of the conventional design, but it can also be determined according to the requirements to take the median value below).
Online UV Ink inkjet printer Mainly for labels of various materials, variable information such as Chinese characters, letters, numbers, one-dimensional bar codes, two-dimensional bar codes, etc. can be sprayed on the label and roll film. The printed content has a bright and shiny appearance, which improves the value of the label. When producing standard labels, the speed is 90 meters per minute, UV ink inkjet coder can be installed on various packaging lines, printing lines, rewinders, and slitting machines.
Aiming at the printing material, customized a UV super black and fast-resistant ink that is very suitable for printing on the surface of the card, which further improves the performance of the product. This UV environmentally friendly ink can be printed on cards with dirty surfaces or small scratches. It can be wiped with solvents such as alcohol and propanol. At the same time, it can be cured with less UV energy, reducing energy consumption.
