Problems solved by technology

[0003] But the existing steel ball type safety coupling needs to be disassembled to add grease after using for a period of time, so it is very inconvenient. At the same time, when adjusting the circumferential force, the device must be disassembled and the adjusting nut adjusted, so it is not easy to use convenient

Abstract

The invention relates to a steel ball type force limiting safety coupling, and belongs to the technical field of couplings. The steel ball type force limiting safety coupling comprises a shell, a first flange, a second flange, a centering sleeve, a guide sleeve, a Belleville spring, a steel ball, a steel bead and a guide rod, and further comprises a first oil injecting hole, a second oil injecting hole and an adjusting disc, wherein an adjusting nut is in threaded transmission connection with the adjusting disc through a thread; the adjusting disc extends out of the shell; and the adjusting disc is positioned through a movable positioning device. The steel ball type force limiting safety coupling can guarantee the sealing effect, and can reduce the deformation and damage of a sealing ring in the assembly process. The steel ball type force limiting safety coupling is convenient to inject oil and adjust the circumferential force.

Description

technical field [0001] The invention relates to a steel ball type force-limiting safety coupling, which belongs to the technical field of couplings. Background technique [0002] The SE30 safety device is an important component of the steel ball safety coupling. When the coupling transmits torque overload, it will automatically disengage, and it will be restored manually and then run again. Chinese patent ZL201220692317.2 discloses a steel ball type force-limiting safety coupling, such as figure 1 As shown, the transmission torque of the safety device is the preloaded elastic force of the disc spring, and the pressure is applied to the centering sleeve through the spring pressure plate→steel ball→guide rod→steel ball to connect the first flange to the second flange and transmit the circumferential force . When the circumferential force applied externally to the first flange and the second flange exceeds the safety device. When the circumferential force is set, the steel b...
