Abstract

The invention relates to a buffer brake comprising a torsion spring, a shifting fork, a friction pair inner plate, a friction pair outer plate, a disc spring, a retaining ring and a bearing. The mechanism is rigidly connected with input and output ends of a transmission chain during normal transmission, the buffering energy absorbing is realized through the torsion spring during inertia overshoot by stalling at the input end and high-inertia load, the friction pair slides to consume energy, and the shock damage to the transmission chain by the inertia kinetic energy is prevented, and finally the transmission chain restores to the stalling angle under the function of the initial torque of the torsion spring. The buffer brake realizes the buffering, energy-consuming and resetting functions of the high-inertia transmission chain and has the characteristics of simple structure and reliable work.

Description

technical field [0001] The invention belongs to the technical field of inertia, and in particular relates to a buffer brake for preventing large inertia impact. technical background [0002] Brakes are usually divided into two types, friction and non-friction, and are a device used to slow down or stop a mechanism or machine. The general damper has a single function and only realizes the function of energy consumption braking. For the load with large inertia, since the transmission chain has a large inertial kinetic energy, it should also have functions such as buffering and reset while braking it, so as to ensure that the gears, motors and other components at the front end of the transmission chain are free from impact. And make the final stop angle (zero position) not offset. [0003] To achieve the above functions, ordinary dampers must be used in conjunction with other buffer mechanisms, which will lead to complex structures, large transmission chains, and increased di...
