Characteristics and Classification of Micro Shaft
micro shaftRelatively small, with high accuracy. Some are also called precision shafts, small shafts, shaft cores, rotor shafts, pins, rivets, guide rods, etc. The main materials are various materials of carbon steel, stainless steel, copper, aluminum, etc. The surface treatment mainly includes galvanizing, nickel, blackening, carburizing and so on. Some industries also require salt spray testing to prevent rusting for days and nights. The main processing procedures are punching, grinding, surface treatment, turning, sorting, packaging, etc. The main processing equipment includes grinders, lathes, tool cars, heat treatment and barrel casting.
micro shaftThe shaft includes a cylindrical shaft body, characterized in that the axial ends of the shaft body are respectively provided with an assembling portion and a positioning portion. The outer wall of the shaft body is provided with an oil supply assembly. The oil supply assembly includes a row of fine oil holes. A fine oil passage is provided inside the main body, the fine oil passage is opened to both end faces of the shaft body, and the fine oil passage is connected with the shaft body. A positioning hole is provided on the end face, and a threaded hole is provided on a side wall of the positioning portion in the radial direction. The utility model is to lubricate the surface of the shaft through a fine oil channel and a fine oil hole to ensure that the surface of the shaft is always covered by lubricating oil, improve the lubrication effect of the micro shaft, and perform positioning. The hole and the screw hole of the positioning member facilitate positioning and assembly by an assembler.
Accordingmicro shaftThe load conditions can be divided:1.The rotating shaft is subjected to both bending moment and torque during rotation. Work is the most common shaft in machinery, such as the shaft in various reducers.2.The spindle is used to support the rotating parts so that they only bear bending moments and do not transmit torque. Some spindles rotate, such as the axle of a railroad car, while some spindles do not rotate, such as the axle supporting the pulley.3.The drive shaft is mainly used to transmit torque without bearing bending moment, such as the long light shaft and the car drive shaft in the crane moving mechanism. The shaft material is mainly carbon steel or alloy steel, but also includes ductile iron or alloy cast iron. The working capacity of the shaft usually depends on the strength and stiffness, but also on the vibration stability at high speed.
