1. Diaphragm coupling diaphragm form: continuous multilateral ring, circular ring, separated connecting rod, spoke, formed diaphragm, wave diaphragm.
2. Characteristics of continuous polygonal ring and circular ring of elastic diaphragm coupling: Each diaphragm coupling is composed of several equal thickness diaphragms. The outer edge of each diaphragm is arc-shaped with good elasticity and simple shape. The processing is convenient, but its elasticity is poor. In addition, the elasticity with fewer edges is better than the elasticity with more edges. However, if the number of edges is too small, the stability is also reduced. When one-way operation is reduced, only half of the rings bear the transmission torque. 3. Diaphragm coupling separating link-shaped features: Each diaphragm consists of a single thin rod to form a polygon, the shape of the rod is simple, and the manufacturing is convenient, but the precise pitch is required, and its working performance is basically the same as that of the continuous polygonal ring. , but low strength and speed, suitable for occasions where the diaphragm coupling size is limited.
4. Characteristics of spokes of diaphragm coupling: Each diaphragm coupling consists of several pieces, and the screw holes on the outer edge and the inner edge of the diaphragm coupling are respectively connected with the main driven half diaphragm coupling. Twisting, the forming hole in the diaphragm is to increase the elasticity, because the elasticity needs the difference between the inner and outer diameter should not be too small, generally in order to transmit small and medium power is appropriate.
5. Characteristics of formed diaphragm coupling diaphragm: Each diaphragm coupling consists of a single diaphragm, and the thickness of the diaphragm decreases from the inner diameter outward to the hyperbolic law, so as to maintain the equal strength condition and its material utilization. High, overall good, especially suitable for high-speed transmission, but the high precision of diaphragm manufacturing.
6, the characteristics of the waveform diaphragm: diaphragm in the axial section waveform, high elasticity, good compensation performance. The thickness of the diaphragm is of equal thickness and unequal thickness.
No lubrication and routine maintenance required
The state of the diaphragm coupling can be detected without disassembling; in addition, during the operation of the equipment, the diaphragm can be inspected with a strobe light, and the torsional rigidity is high, and zero rotation is achieved;
If the alignment is accurate, the diaphragm coupling will not be damaged for a lifetime and its life will be infinitely long;
Diaphragm couplings have no wear parts, but are used in various harsh working conditions.
If the offset error is within a limited range, the diaphragm coupling will have the same long life as the device;
The technology and performance of DC Axial Fans have fully reached a mature stage,
and new technologies are constantly emerging. The size of the fan is from 8mm to 280mm, the voltage is 5V, 12V, 24V, 48V, 110V, 220V, 380V, with a square, round, olive shape, etc.The
working principle of the DC fan is realized according to the energy conversion, that is,
electric energy, electromagnetic energy, mechanical energy and kinetic energy. Its circuit principle is generally divided into various forms, the use of different circuits, the performance of the fan will be different.
In simple terms, by changing the input to the brushless motor stator coil of the alternating current wave frequency and waveform, the formation of a geometric axis to the motor winding coil in magnetic field around the magnetic field of permanent magnet on the rotor rotation, the motor will turn up, the quantity, performance and magnet motor magnetic flux the motor input voltage strength, size and other factors, it has a great relationship with the control performance of the brushless motor, because the input DC current to the electronic governor, into 3 alternating current, also need to receive a control signal from the remote control receiver, control motor speed, in order to meet the need to use model. In general, the structure of the brushless motor is quite simple, really decided its performance or brushless electronic governor, electronic governor to a good overall control a single-chip control program design, circuit design, complex processing process, so the price is much higher than the brush motor.
