What is one of the important parts of motor?
Motor shaft (equipment shaft) is one of the important parts of the motor. It serves as a link between the mechanical and electrical energy conversion between the motor and the equipment, supporting the rotating parts, transmitting torque and determining the relative position between the rotating parts and the stator.
How to reduce the design cost and time of motor shaft?
Motor is one of the most widely used equipment in various departments of national economy. Motor shaft performance has a great influence on motor performance, and it is the key component of motor. The structure of the motor shaft is mainly composed of several (6 ~ 8) ribs welded together to form the main shaft. The silicon and the coil around the ribs use the magnetic field to generate current to work. In the work of the motor, the combination of the rib and the shaft is affected by the electromagnetic force due to the periodic action of the motor shaft, and there is a large stress concentration. In addition, the conventional design and general process defects of the shaft will produce fatigue cracks, which will eventually lead to the fracture failure of the parts. Therefore, the success of motor design depends on the motor shaft to a certain extent. Design. In the past design, according to the performance requirements of the motor and the prototype design experience of the motor shaft, the performance of the motor shaft can be obtained after the test; When the motor shaft performance does not meet the design requirements, it is necessary to adjust the motor shaft to adjust the corresponding structural parameters, and then retest.
Requirements and inspection of chromium plating thickness for precision slender shaft
In the production of precision long and thin shafts, the surface needs to be chrome plated, and the thickness of the chrome plating layer has become a concern of many people in the industry. Generally speaking, how much thickness can meet the requirements? How to check after production? The following is to explore these issues.
Heat treatment of fan shaft
The main advantage of heat treatment is to eliminate the casting stress, lower the surface hardness of the fan shaft forgings, and improve the machining function; Adjust and improve the overheat and coarse structure formed in the process of casting, the asymmetry of chemical composition and metallographic structure in the low vertical fan shaft forging, refine the grain, and improve the comprehensive function of the product.
The axis you don't know
Rotating shaft is an important part, which plays a key role in the whole. Rotating shaft and accessories play an important role in the whole set of product materials. It will directly affect the comprehensive quality of products, and have a great impact on the normal use and service life of products. The key to the service life of rotating shaft is the maintenance of moving parts. It can be wiped with brightener to increase brightness. Hinge, hanging wheel, caster and other moving parts may reduce performance due to dust adhesion during long-term movement. One or two drops of lubricating oil every half a year can keep it smooth
What harm will the shaft be if it is worn
The main parts between products must be applied to the rotating shaft. The shaft used to bear both bending moment and torque is called the rotating shaft. And if it is worn, what kind of harm will it bring?
You ignore the axis and the secrets
Rotating shaft is a part that is often ignored. Now let's briefly introduce some of its secrets.
What is the use of spindle core and how to select it?
Fixed mandrel, different structure, different stress, gear with different. The installation method is also different. General two kinds of fit: sliding fit and interference fit. Sliding fit: such as sliding gear, align the shaft with the position and angle and push it in gently. Interference fit: when the interference is small, the heavy hammer can be used to knock the shaft end to drive the shaft. Before knocking, cover the shaft end with other objects to avoid damaging the shaft end.
How to choose and purchase eccentric shaft gear reduction motor with low cost?
The manufacturer purchased the eccentric shaft gear reducer motor of the juicer motor to achieve the effect of fine grinding, low decibel and high power. In the selection of motor, the high-precision transmission system effect of eccentric shaft gearbox is the most important. How to further understand the process of eccentric shaft gear motor, buy a low-cost and high-quality juice machine reducer motor?
What materials should be selected for motor shaft head wear maintenance
The motor is mainly composed of stator, rotor, bearing, frame, end cover, fan, etc.
A part of the magnetic circuit of a stator motor on which a stator winding is placed. The stator winding is the circuit part of the motor, which generates the rotating magnetic field by the current.
