There are many kinds of materials in the shaft. The design is mainly based on the requirements of the shaft strength, stiffness, wear resistance and other heat treatment methods to achieve these requirements, taking into account the manufacturing process to be selected, and strive to be economical and reasonable.
Common materials for the shaft are 35, 45, 50 high-quality carbon steel, the most commonly used is 45 steel. For smaller or less loaded axles, common carbon steels such as A3 and A5 can also be used. For larger forces, shaft size and weight restrictions, as well as some special requirements of the shaft, the alloy steel can be used.
Ductile iron and some high-strength cast iron, cast because of good performance, easy to cast into complex shapes, and good damping properties, stress concentration sensitivity is low, the impact of fulcrum displacement is small, it is often used to create complex shape of the shaft.
In particular, the rare earth-magnesium ductile iron developed in our country has the advantages of good impact toughness, reduced wear, vibration absorption and less sensitivity to stress concentration. It has been used to make important shaft parts on automobiles, tractors and machine tools.
Depending on the working conditions, the shaft may be subjected to overall or surface treatment before or after processing as well as surface strengthening treatment such as shot peening and chemical treatment such as carburizing, nitriding, nitriding, etc. to enhance its strength Especially fatigue strength) and wear, corrosion resistance and other properties.
At normal operating temperatures, the modulus of elasticity of alloyed steel is similar to that of carbon steel, so alloy steel is not suitable for increasing the rigidity of the shaft.
Shaft generally by the rolling of steel or forgings by cutting manufacturing. Shaft diameter smaller can be made with round bars; For important, large diameter or step diameter larger shaft, using forging billet. To save metal and improve workmanship, large diameter shafts can also be made hollow, with welded or forged flanges.
For the shape of the complex axis (such as camshaft, crankshaft) can be cast. Depending on the job requirements, the spool axis plays the role of support reel, gear, and ratchet. So choose 45 steel (quenched) as the mandrel material. 45 steel (quenched and tempered) performance parameters (3-4).
Design of Mine Hoist Winch Frequency Control System
Winch Factory shall always provide winches with cutting-edge technology. The winch with wireless remote control is one of a smart winch. Right here in this post, the company would like to introduce the technology we have employed in our winch wireless remote control.

At present, mine hoist winch control system commonly uses winding motor rotor resistor string way to speed control, the system has the following disadvantages:
A lot of power consumption in the slip resistance, resulting in a serious waste of energy, while the installation of resistors needs to take up a lot of space.
The control system is complex, resulting in a high failure rate of the system. The contractor, resistor, and brush of the wound motor are easily damaged and the maintenance workload is heavy, which directly affects the production efficiency.
Low-speed and creeping stages need to rely on brake pads friction roller speed control, especially in the load changes, it is difficult to achieve constant deceleration control, resulting in speed control is not continuous, the speed control performance is poor.
Start-up and shift shock current, resulting in a large mechanical shock, resulting in the greatly reduced service life of the motor, and extremely prone to “off the road” phenomenon.
The degree of automation is not high, increasing the cost of mining, affecting the yield.
Low voltage and low speed start torque are small, with poor load capacity, cannot achieve constant torque boost.
The use of variable frequency speed control system can be very good to overcome the above shortcomings, this paper to the scenery brand elevator inverter, for example, details of the frequency control system used in mine hoist system solutions.
The Advantages of Frequency Control System
In the range of ± 20% of the fluctuation of the power grid, the constant torque will not increase because of the fluctuation of the power grid.
Realize the motor soft-start, start torque, with load capacity.
The motor can achieve stepless speed regulation, plus, deceleration process is very smooth, small current impact, greatly reducing the mechanical impact strength.
The use of chip unified control and PLC external circuit interface combination, the speed control system with high reliability while using PLC’s powerful control capabilities to achieve flexible control.The use of chip unified control and PLC external circuit interface combination, the speed control system with high reliability while using PLC’s powerful control capabilities to achieve flexible control.
In addition to over-voltage, under-voltage, overload, overheating, short-circuit protection itself, but also has a chain of external protection control, including the brake signal and positive and reverse signal chain, inverter fault signal and System safety loop chain, the machine equipped with automatic deceleration procedures.
