Jiaozuo brake

The electric hydraulic brake adopts advanced AC braking technology, which is directly powered by 3-phase 380V power supply. Without rectifier device, it has a wide range of braking torque adjustment, and can achieve two-stage speed regulation. It has the advantages of fast braking and reliable braking, and is suitable for spindle transmission and auxiliary transmission in various machines that require fast stop, accurate positioning, reciprocating operation, and prevent sliding. Such as lifting machinery, transportation machinery, packaging machinery, food machinery, printing machinery, woodworking machinery, deceleration machinery, metallurgical machinery, forging machinery, construction machinery, etc.

Electric hydraulic brakes typically brake in worm gear transmission, where the worm is the active component and the worm gear is the passive component.

(1) Features of Worm drive

A single stage transmission can achieve a large transmission ratio, with a compact structure, stable transmission, and no noise, but low transmission efficiency.

(2) Judgment of Turbine Steering in Worm drive

In Worm drive, the relationship between the worm and the turbine steering depends on the relative position between them, the rotation direction of the worm and its rotation direction.

The left or right hand rule is used to determine the direction of the turbine relative to the worm, the right hand rule is used when the gear shift worm is right-handed (the worm is also divided into left and right rotation and the judgment method is the same as that of the helical gear direction), and the left hand rule is used when the worm is left-handed. Bend the four fingers to point to the rotation direction of the worm (the straight arrow indicates the Circular motion direction of the visible side of the worm), and the opposite direction of the thumb is the movement direction of the worm relative to the worm. The performance of the materials and components used in the brake should comply with relevant standards and regulations, undergo factory inspection, and be able to pass corresponding tests on the product.

The magnetic material of the brake should be low-carbon high-quality carbon steel with good magnetic conductivity, electrical pure iron, and other magnetic materials with magnetic conductivity not lower than the above materials.

The soft magnetic magnetic powder used in the brake should undergo stability treatment, and its physical and magnetic properties should comply with the provisions of relevant specialized technical conditions and standards.

The insulation level of the excitation coil shall not be lower than level E.

The outlet wire of the brake adopts high-temperature resistant, high-strength, and well insulated wires.

The brake power supply device must be reliable.

Electric hydraulic brakes generally have some symptoms before the brake malfunctions, such as shaking of the steering wheel during braking or a fine scream during braking. This all reflects a problem with the brake system, and it is time to replace or repair the brake discs or pads. Because the brake disc is damaged, it will cause uneven force on the brake disc during braking, causing the steering wheel to shake. A very thin and sharp metal friction sound is emitted, indicating that the electric hydraulic brake pads have been worn very thin and need to be replaced in a timely manner

Spiral transmission uses a pair of screws and nuts to achieve transmission requirements, mainly used to convert rotary motion into linear motion, while transmitting motion and power.

Classification of screw drives for electric hydraulic brakes:

1) Transmission screw: Mainly used to transmit power, requiring a smaller torque to generate a larger axial thrust to overcome working resistance. Such as the spiral of various lifting or pressure devices. This type of transmission screw mainly bears a large axial force, usually abbreviated as work, with short working time and low working speed each time.

2) Conduction spiral: Mainly used for transmitting motion, sometimes also subjected to significant axial loads. For example, the screw of the machine tool feed mechanism. The conductive spiral mainly operates continuously for a long time and has a high working speed, therefore requiring high transmission accuracy.

3) Adjusting the screw: to adjust and fix the relative position of the parts. Spiral of fine adjustment mechanisms in machine tools, instruments, and testing devices. The adjustment screw does not rotate frequently and is usually adjusted under no load.

The characteristics of spiral transmission include high transmission accuracy, stable operation without noise, easy self-locking, and the ability to transmit large amounts of power.
