Self-help obstacle-crossing type overload protector

Abstract

The invention discloses a self-help obstacle-crossing type overload protector. The self-help obstacle-crossing type overload protector mainly comprises a driving shaft part, a planet gear part, and adriven shaft part, and the driving shaft part comprises a driving shaft, a driving shaft spring, a big spline-tooth driving shaft gear, a driving shaft snap ring, a driving spline shaft, a driving spline shaft spring, a small spline-gear driving spline shaft gear, a flat key, a driving spline shaft end cap, and a driving spline shaft end cap bolt. The overload protector has two stages of driving;the first stage of driving is that a load is directly driven by a motor; when the small spline-gear driving spline shaft gear slips at the first stage of driving, under the condition that the output power of the motor does not change, the overload protector automatically gets into the second stage of driving, and an obstacle is crossed by increasing torque. The self-help obstacle-crossing type overload protector can realize self-help obstacle crossing, protecting the motor from being burnt out due to stalling, moreover, overload protection torque can be adjusted, the labor intensity of workerscan be reduced, and the efficiency of production can be improved.

Description

technical field [0001] The invention relates to an overload protection device, in particular to a self-help obstacle-surmounting overload protection device. Background technique [0002] With the continuous development of the machinery industry, the occasions that the mechanical system is oriented to are becoming more and more complex. For some occasions with instantaneous large loads, such as crushers, etc., it is often necessary to install overload protection devices to avoid damage to power components such as motors or other key components, which can improve the service life of the mechanical system and reduce the maintenance cost of the mechanical system. . The current overload protection devices mainly include friction type and meshing type. However, although these two types of overload protection devices can protect the source moving parts and key components such as motors from damage, they cannot self-override when encountering an overload. Obstacles still require m...

The current overload protection devices mainly include friction type and meshing type. However, although these two types of overload protection devices can protect the source moving parts and key components such as motors from damage, they cannot self-override when encountering an overload. Obstacles, manual participation is still required, resulting in low production efficiency and increased labor intensity of workers
