Problems solved by technology

These devices have their own shortcomings in application; liquid viscosity technology has large starting current, rapid oil temperature rise, difficult maintenance and high cost
When the frequency conversion technology is used in high-power applications, the higher the power of the electronic components, the more expensive the cost, and the higher the power, the greater the heat. In use, the automatic governor controlled by electro-hydraulic has complex structure, high cost and limited adaptability to power.

Abstract

The invention provides an elastic-resistance mechanical braking device which comprises a casing, a ratchet gear, a ratchet ring, a planet transmission system and a controlling device. The planet transmission system is assembled in the casing, the ratchet gear is assembled on a planet inner gear ring of the planet transmission system, a ratchet combined ring is wrapped on a gear edge of the ratchet gear and connected with the controlling device, and lubricating oil is filled in a cavity of the casing. The elastic-resistance mechanical braking device has the advantage that the mechanical braking device can generate linear resistance to a running locomotive and can realize stepless speed adjusting, soft starting, soft parking, overload protecting and multipoint driving power balancing.

Description

technical field [0001] The invention relates to the technical field of equipment braking, in particular to an elastic resistance mechanical braking device. Background technique [0002] Since the invention of the machine, human beings have been researching the brake device as a key point. The friction resistance brake device is the most primitive, but it is still the most widely used brake device. Its advantages lie in its simple structure, economy, and convenient operation and maintenance. . The disadvantage is that when friction generates heat, the power is too large, and the braking time is too long, the friction lining will be ablated and become invalid during the braking process. Then people developed a wide variety of soft start devices, such as hydraulic couplings, hydraulic torque converters, computer-controlled automatic speed control devices, variable pressure soft starters, variable frequency soft starters, liquid variable resistance soft starters, hydraulic soft...
