The role of the motor shaft

The motor shaft is based on the larger output torque of the motor. If it is a small motor, it is not necessary to manufacture key type and keyway type motors. The motor shaft is typically made of carbon steel. Only suitable for selecting motor shaft processing plants to find quality assurance, 35# and 45# can be. General use 45# steel. Both of these materials belong to medium carbon steel, and their strength, stiffness and toughness can meet the working requirements of the motor shaft. The motor shaft has high speed and low torque, and is made of 45# steel without other heat treatment

Introduction to the protection of the lead screw

Introduction to the protection of the screw: The ball screw is an ideal product that converts rotary motion into linear motion, or converts linear motion into rotary motion. Ball screw is a commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or to convert torque into axial repetitive force, with high precision and reversibility. Because the friction resistance of the ball screw is small, it is widely used in various industrial equipment and precision instruments.

Guide rod: Basic knowledge of anode guide rod

The anode guide rod is a new model that can easily replace the steel column. At the same time, when the weld between the steel column and the steel claw seat is cracked, it can be repaired or re-welded. The material of the explosive solder bump is saved, and at the same time, the heating degree of the explosive solder bump during the soldering process is relatively small. Due to the long use time, transportation and open storage, all anode guide rods have different degrees of bending and corrosion. Explosive weld nugget cracking, steel claw cracking, claw rotting, and dropping can still occur on some anode guides. Defects such as claws. If these anode wires are not repaired, they cannot be used for electrolysis.

Common faults of rotating shaft

Shaft wear is a common equipment problem in shaft use, which is mainly caused by the metal characteristics of the shaft: although the metal hardness is high, it has poor resistance (it cannot be restored after deformation), poor impact resistance, poor fatigue resistance, and easy to cause adhesive wear, Abrasive wear, fatigue wear and fretting wear. The wear of most shafts is not easy to detect, only when the machine temperature is high, the runout range is large, abnormal noise, etc., Will not be noticed. However, when people found out, most of the drive shaft had worn out, causing the machine to stop.

Why does the screw rod have grinding cracks after intermediate frequency quenching?

At present, large screw usually use medium frequency induction hardening. In production, it often happens that the hardened (tempered) screw is screwed into the thread and checked by magnetic inspection. The axial direction is often found to appear on the arc of the thread raceway. In the process of thread grinding, the naked eye can even find cracks or mesh cracks, resulting in the screw being scrapped. This not only causes direct economic losses to the enterprise, but also brings greater pressure to the production of the enterprise due to various factors that cause the problem.
