I haven't seen such a beautiful worm and worm coupling in ten years. Do you like it?aven't seen such a beautiful worm and worm coupling in ten years. Do you like it?
Worm gear and worm reducer is a kind of power transmission mechanism.
Expand text… By using the speed converter of gears, the number of rotations of motor (motor) is reduced to the desired number of rotations, and a mechanism with larger torque is obtained. At present, the reducer is widely used in the transmission mechanism of power and motion.
Its traces can be seen in the transmission system of all kinds of machinery, from ships, automobiles, locomotives, heavy machinery for construction, processing machines and automatic production equipment used in machinery industry, to household appliances, clocks and watches commonly used in daily life, etc. Its application can be seen from the transmission of large power, to the transmission of small loads and accurate angle. In industrial application, the reducer has the function of reducing speed and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.

Why is the decelerator an industrial beauty?
From high-speed power devices such as motors, internal combustion engines, to the working end of power devices, a process of reducing speed and increasing torque is needed.
Expand text… Reducer is the power transmission mechanism to realize this process. There are many kinds of gear reducers. They are very low-key in everyday life, but they are actually everywhere. They basically use gears. Many times they are called gearboxes, gearboxes or gearboxes.
Bloodhound SSC is driven by EJ200, a jet engine of the European Typhoon fighter, and a solid-liquid hybrid rocket engine. Even if it travels faster than the speed of sound, the wheel speed of Bloodhound SSC must not be equal to the speed of the engine, so it needs a decelerator. Of course, such a powerful land rocket needs a decelerator that can not be bought in the market. It is specially customized by engineers from the shell to the gear.
Common Faults and Detailed Solutions of Six Major Motors
In the process of using the motor, it is more or less possible to cause faults due to various problems, such as overload operation of the motor during operation,
Expand text… resulting in fever or faulty wiring of the motor, etc.
1. When the timing is switched on, the motor can not start, but there is buzz.

Possible reasons:

(1) The power supply is not fully connected to single-phase start;

(2) Motor overload;

(3) being stuck by towed machinery;

(4) The winding motor rotor circuit is open and broken;

(5) The stator internal head position is wrong, or there is a break or short circuit.

Processing methods:

(1) Check the contacts of the power supply wire, motor lead-out wire, fuse and switch, find out the position of circuit break and eliminate it;

(2) No-load or half-load starting after unloading;

(3) Check the dragged machinery and troubleshoot it;

(4) Check the connection of brushes, sliding rings and starting resistors.

(5) Re-judge the beginning and end of the three-phase, and check whether the three-phase winding has a canned wire and short circuit.
2. It is difficult to start the motor. When the rated load is added, the speed is low.

Possible reasons:

(1) The power supply voltage is low;

(2) The original angle connection was misconnected into star connection;

(3) The end of cage bars of squirrel cage rotor is unsoldered, loosened or broken.

Processing methods:

(1) Increase the voltage;

(2) Check the connection method of nameplate and correct the connection mode of stator winding;

(3) Examination and symptomatic treatment.
