Abstract
The invention relates to a milling cutter shaft including a milling shaft, a plurality of rows of middle gear milling assemblies are arranged at the middle section of the milling shaft in a surrounding manner; a plurality of left gear milling assemblies and a plurality of right gear milling assemblies are arranged on the left section and the right section of the outer circumferential face of the milling shaft correspondingly. The multiple left gear milling assemblies and the multiple right gear milling assemblies are arranged in a reverse spiral line shape from the middle section of the milling shaft to the two ends of the milling shaft, the multiple side gear milling assemblies are arranged on the left side and the right side of the outer circumferential face of the milling shaft in an annular manner, all-directional non-blind-area arrangement is achieved, and the milling effect and the milling efficiency are greatly improved. Besides, the left tool apron and the right tool apron areinstalled by adopting welding templates with special specifications to be matched with cushion blocks and positioning pins through a special process method, so that accurate installation can be realized, the installation position deviation between the tool aprons is reduced, and the milling effect is improved.
Description
technical field [0001] The invention relates to a milling cutter shaft and a production method thereof, belonging to the technical field of engineering machinery. Background technique [0002] Milling machine is one of the main types of asphalt pavement maintenance construction machinery and one of the main equipment for asphalt concrete road maintenance construction. It is mainly used for excavation and renovation of asphalt concrete surfaces such as highways, urban roads, airports, and freight yards. Among them, the milling device is the working device of the milling machine. The asphalt concrete surface layer of the old pavement is excavated through the milling device, and then the discarded asphalt material after milling is recycled. The foamed asphalt cold recycling technology is used to recycle Asphalt pavement materials and cement-stabilized base materials are recycled to give full play to the "surplus value" of old asphalt mixtures, promote the recycling of old pavem...
