One of the problems in rolling a large-mass helical gear is how to return the hob conveniently and efficiently in the middle for the next cutting, and there is no misalignment or disorder. By rolling the large-mass helical gear with the micro-tooth error method, the machine tool operation method can be simplified almost as if the ordinary helical gear is being machined, and the above-mentioned helical gear can be satisfactorily solved.
The square nut is one of the welding nuts. The welding method is believed to be known to all. It is to use high temperature to melt some metal and weld it between the two products to play a fastening role. The fastening effect of this connection will be very good and will not be easy to loosen. It can also be used with bolts. Square nuts are mainly used in electric power engineering, road traffic, home building materials and other industries.
